EarthTalk: Cloud Computing's Substantial Footprint

EarthTalkCloudComputing

Dear EarthTalk
: Why is Greenpeace upset with some leading tech companies for so-called “dirty cloud computing?” Can you explain?
-- Jeremy Wilkins, Waco, TX

Leading tech companies like Google, Apple and Microsoft are now offering unprecedented amounts of data storage and access to “apps” on huge Internet-connected servers, saving consumers and businesses the hassle of installing and running programs and storing information on their own local computers.

This emerging trend, dubbed “cloud computing,” means that these providers have had to scale up their power consumption considerably, as they are increasingly responsible for providing more and more of the computing horsepower required by the world’s two billion Internet users. No doubt, sharing such resources on centralized servers is more efficient than every individual and business running their own versions separately. In fact, the research firm Verdantix estimates that companies off-loading data and services to cloud servers could save $12 billion off their energy bills and reduce greenhouse gas emissions by 85 million metric tons within the next decade. But for the greenhouse gas savings to be realized, the companies offering cloud computing services need to make the right energy choices.

Greenpeace has been tracking sustainability among tech companies for over a decade, and recently released a report, “How Green is Your Cloud?” assessing the green footprint of the move to cloud computing. According to the analysis, some of the major players (Google, Facebook and Yahoo) have gone to great lengths to ensure that significant amounts of the power they need come from clean, green sources like wind and solar. But Greenpeace chastises others (Apple, Amazon and Microsoft) for relying on so-called “dirtier” sources of power, such as coal and nuclear, to run their huge data centers.

“When people around the world share their music or photos on the cloud, they want to know that the cloud is powered by clean, safe energy,” says Gary Cook, a Senior Policy Analyst with Greenpeace. “Yet highly innovative and profitable companies like Apple, Amazon and Microsoft are building data centers powered by coal and acting like their customers won’t know or won't care. They’re wrong.”

Greenpeace’s report evaluates 14 major tech firms and the electricity supply chains in use across more than 80 different data centers that power cloud-based services. Some of the largest data centers are in buildings so big they are visible from space and use as much power as 250,000 European homes. If the cloud were its own country, says Greenpeace, it would rank 5th in the world in electricity consumption.

“
Companies like Google, Yahoo and Facebook are beginning to lead the sector down a clean energy pathway through innovations in energy efficiency, prioritizing renewable energy access when siting their data centers, and demanding better energy options from utilities and government decision-makers,” reports Greenpeace. But unfortunately the majority of the industry is not marching in step. As such, Greenpeace is calling on all tech companies with cloud services to develop siting policies based on access to clean energy sources, invest in or directly purchase renewable energy, be transparent about their energy usage, share innovative solutions so the sector as a whole can improve, and demand that governments and utilities increase the percentage of clean, green power available on the grid.

EarthTalk: A Kid's Life--Marketing Messages and Sales Pitches

EarthTalkKidsCommercialMessages

Dear EarthTalk
: Are all the commercial messages kids are bombarded with today having any noticeable negative effects? And if so what can a concerned parent like me do to limit my own kids’ exposure to so much advertising and marketing? -- Jason Baldino, Somerset, NJ

No doubt, marketers are hard at work targeting our children with their messages and creating young demand for their products.
Companies in the U.S. today spend some $17 billion yearly advertising to children, a 150-fold increase from just a few decades ago. Some cash-strapped school districts have even started selling ads on and sometimes in their school buses as a way to bolster sagging education budgets. To be an American kid today is to be bombarded with marketing messages and sales pitches. It’s no wonder that, given the amount of advertising and marketing they endure, young people in our society are experiencing record levels of obesity and problems with credit card debt.

According to the non-profit Center for a New American Dream (CNAD), a leading proponent for more ecologically sustainable and community-oriented lifestyles in the United States, this incessant marketing is turning our children “into little consumers, alienating them from nature, getting them used to unhealthy diets filled with junk foods, and making them want ever more stuff.” The group points to several disturbing studies, such as one that showed how U.S. children could recognize more Pokemon characters than common wildlife species, while another found that the average American kid is exposed to more than 25,000 television ads spanning some 10,700 minutes over the course of just one year.

The result of all this aggressive marketing to kids is not just excessive materialism and obesity, but also a host of other problems including depression, anxiety, low self-esteem, eating disorders, increased violence, and family stress. “Economically, societally and ecologically,” CNAD reports, “this is unsustainable and not the best path for children.”

Against this backdrop of media and marketing saturation, what can be done to help steer our kids in a more healthy direction? Given that shielding American kids from these messages would be nearly impossible, the next best thing is teaching them how to parse through the different come-ons and solicitations they are exposed to these days at nearly every turn. CNAD’s free, downloadable 32-page booklet “Tips for Parenting in a Commercial Culture” offers loads of useful information on how to limit kids’ exposure to commercial influences that come via the television, computer or mail slot, and replacing those lost hours with new opportunities for more beneficial activities. Examples abound: playing board or card games, going on a walk or hike, riding bikes, and much more. The booklet also elaborates on how to limit or rid commercial influences in schools and other places where kids spend time away from home.

Another great resource for parents and teachers looking to reduce commercial influences on kids is the Campaign for a Commercial-Free Childhood, a coalition of more than two dozen other groups started by consumer advocate and author Susan Linn. The coalition advocates for the adoption of government policies that limit corporate marketers’ access to kids and works to mobilize parents, educators and health care providers to stop the commercial exploitation of children. Teachers love the coalition’s free downloadable Guide to Commercial-Free Book Fairs while concerned parents can download the Guide to Commercial-Free Holidays in order to help themselves and their kids resist the hype.

EarthTalk: Safe Alternatives to Artificial Food Colorings and Dyes

EarthTalkFoodColoring
Dear EarthTalk
: Ever since the red dye #2 scare in the 1970s I’ve been wary of using food colorings or buying food that appears to contain them. Are there natural and healthy food colorings? -- Nancy McFarlane, Methuen, MA

Many of us are still wary of food dyes because of reports about links between red dye #2 and cancer in the 1970s. While red dye #2 was subsequently banned from products sold in the United States, many health-conscious consumers continue to avoid foods with other artificial colors or dyes—even though the U.S. Food and Drug Administration (FDA) still considers them safe for human consumption.

But a 2010 analysis of past research on links between food dyes and health by the Center for Science in the Public Interest (CSPI) found compelling evidence that ingestion of artificial dyes can contribute to hyperactivity, restlessness and attention problems in some children—particularly those with ADHD. “What’s more, the studies suggested that removing dyes from those children’s diet was a quarter to half as effective in reducing those symptoms as giving the kids Ritalin or other stimulants,” reports Nancy Cordes, CBS News’ Consumer Safety Correspondent. “In other words, certain kids with ADHD might not need drugs if the artificial dyes were removed from their diets.” Several commonly used artificial food dyes are suspected carcinogens as well.

While it might be impossible to prevent your children from eating anything with artificial dye, you can do your part by shopping at Whole Foods or Trader Joe’s—both chains have banned products that use artificial dyes and carry all-natural food coloring for home cooking and baking projects.

One brand to look for is India Tree, which makes a line of food coloring derived from vegetable colorants. The company’s “Nature’s Colors
Natural Decorating Colors” contain no corn syrup or synthetic dyes, and are highly recommended for coloring icing in rich jewel tones or soft pastels.

Another company specializing in natural (as well as organic) food colors is Nature’s Flavors, whose products are widely used commercially in ice cream, baked goods, frosting, dairy products, syrups, sauces, beverages and even hair colors. The company recently began to sell their products to consumers, as well, through retail stores.
They use a variety of plant materials, including beets, turmeric root, annatto seeds, purple carrot, purple cabbage, gardenia flowers, hibiscus flowers and grape skin. “Our natural food colors are made from plants and contain powerful antioxidants, which help the body repair itself from the effects of oxidation,” claims Nature’s Flavors. “Using natural or organic food colors may actually help the brain and slow down the effects of aging.”

Another leading maker of all-natural food coloring is Chefmaster, whose products can be found at Whole Foods and other natural and high end food retailers, as well as on amazon.com and elsewhere online.

CSPI would like
the FDA to ban eight of the most common artificial dyes, or at least affix a warning label to products that contain them: “Warning: The artificial coloring in this food causes hyperactivity and behavioral problems in some children.” In the meantime, concerned eaters should stick with products, stores and restaurants that use natural ingredients.

EarthTalk: A Look At the Dramatic Rise In U.S. Asthma Cases

EarthTalkAsthma
Dear EarthTalk
: Is it true that asthma rates in the U.S. have doubled in the last three decades? What's behind this troubling trend and what can we do to reverse it? -- Patrick, via e-mail

Asthma is on the rise across the U.S., doubling since the 1980s. According to the Environmental Defense Fund (EDF), most people who develop asthma likely have a genetic predisposition but also probably experienced “critical environmental exposures during the first years of life.” Asthma rates are highest in urban areas where auto and industrial emissions make for difficult breathing. But air quality in U.S. cities has improved in the last few decades, leaving researchers puzzled as to what’s behind the trend.

One theory is that better hygiene in developed countries means that Westerners have less exposure to bacteria, viruses and parasites, altering our immune response with the result being increased risk for allergic diseases like asthma. Indeed, Western asthma rates are 50 times higher than in rural Africa. While this “hygiene hypothesis” may be part of the story, researchers believe that there are also other factors.

Some studies have shown a correlation between asthma and obesity, though a direct link is hard to prove. Other research has shown that psychological stress can trigger asthma attacks in those already predisposed.
Dr. Harold Nelson, professor of medicine at the National Jewish Health in Denver, explained in a 2009 New York Times blog post that increased acetaminophen (i.e. Tylenol) use in young children, exposure to household cleaning sprays, and lack of Vitamin D also likely contribute to rising asthma rates. But how?

P
ediatricians recommend against giving young children aspirin today, given the increased risk of Reye’s syndrome, so many parents now use acetaminophen to relieve pain and reduce fever. But acetaminophen lowers levels of the antioxidant glutathione, resulting in an increased asthma risk. A 2008 study found that use of acetaminophen in the first year of life was associated with a 46 percent increase in the prevalence of asthma symptoms among a study group of 200,000 six- and seven-year-olds.

In regard to household cleaners, frequent inhaling of the spray mist from glass cleaners and air fresheners among other products irritates the lungs and increases the risk of developing asthma. A 2007 study found that European adults who used spray cleaners four days a week faced double the risk of developing asthma symptoms, while weekly use of cleaners increased the risk by 50 percent.

The link between Vitamin D deficiency and asthma comes from several studies on the topic over the last decade showing that low levels of Vitamin D in pregnant mothers result in more asthma in offspring. Those who spend lots of time indoors are particularly vulnerable to Vitamin D deficiency, as exposure to sunlight increases the body’s ability to produce the important nutrient.

Dr. Nelson says that people can take steps to lower their exposure to these “new” asthma risk factors. For one, forego spray cleaners and air fresheners for liquids and pump sprays that don’t produce a fine mist. Pregnant women might consider Vitamin D supplements. And parents should discuss pain relievers with their doctor and consider alternating different types so kids don’t get overexposed to any particular one.

EarthTalk: Should You Take Echinacea For Your Cold?

EarthTalkEchinacea
Dear EarthTalk
: What’s the story with Echinacea? Many herb teas contain it, and many people swear by it as a cold remedy. But I’ve also seen headlines saying that the herb has no medicinal value whatsoever. Can you set the record straight? -- Arlene Hixson, Portland, ME

Echinacea, also known as purple coneflower, has gained popularity in recent years as a nutritional supplement that proponents believe is helpful in staving off the common cold and shortening its duration. But given the variation between dosages and formulations—such herbs are not regulated as medical drugs by the U.S Food and Drug Administration (FDA) and so makers have little incentive to standardize—it’s hard to get definitive answers as to Echinacea's effectiveness.

Historically, Native Americans relied on the root of Echinacea to numb toothache pain and treat dyspepsia as well as snake, insect and spider bites. While some modern day folks rely on Echinacea just based on this anecdotal evidence, scientific studies have verified that the herb can be effective. To wit, a 2008 University of Connecticut review of 14 different clinical trials of Echinacea use found that taking the supplement reduced the chances of getting a cold by 31 percent, and helped people get over cold and flu symptoms a day and a half earlier than those who didn’t take it.

Researchers initially thought Echinacea’s effectiveness was due to its immune-boosting traits, but they now believe instead that the herb works more as an anti-inflammatory agent. A 2009 University of British Columbia study found that typical commercially available Echinacea preparations are effective in reducing the body’s production of inflammatory proteins in human bronchial cells. In layman’s terms, this means that Echinacea can help lessen the annoying symptoms of common colds, the flu and other respiratory ailments. Furthermore, the study found that Echinacea is just as effective in reducing bronchial inflammation whether it is consumed before or after a viral infection sets in, indicating that taking moderate doses on a regular basis during cold season can help prevent some bronchial irritation if and when cold symptoms begin.

Interestingly, though, a 2010 study of 719 participants in Wisconsin focusing on illness duration and severity found that the duration of the common cold could be shortened by taking a pill of some sort, whether Echinacea or a placebo with no active ingredients. But this study merely underscored the importance of psychological factors in fighting illness and did not say that Echinacea isn’t effective.

Given the lack of FDA oversight of herbs, different formulations may contain vastly different amounts of Echinacea. A 2004 evaluation of 19 different Echinacea brands by the non-profit Consumers Union and published in Consumer Reports found that the amount of Echinacea actually present in supplements varied considerably from brand to brand—and even in some cases from bottle to bottle of the same brand. The magazine recommended a few brands as “best picks,” including Spring Valley, Origin and Sundown, all which featured high concentrations of Echinacea and reliable dosage amounts from pill to pill.

Before taking the Echinacea plunge, beware that the herb can cause allergic reactions in some people and may interact negatively with some common medications. Researchers warn that anyone with autoimmune disease or a handful of other illnesses should not take Echinacea without first consulting with their doctor.

EarthTalk: Recycled PET Carpeting in Nurseries, Better for the Environment, Safe for Baby?

Babycarpet


Dear EarthTalk
: I have a carpet made out of recycled PET bottles in my baby’s room and I started noticing a lot of the fibers on our clothes and even in my mouth! Is it dangerous for me or my baby to be in contact with and possibly ingest these fibers? -- Ashley Riccaboni, via e-mail

The jury is still out as to whether PET plastics can leach contaminants into our systems, but most reputable consumer advocates seem to think the stuff is relatively benign. That said, it can’t be good to ingest carpet fibers of any kind, and a 2009 study by German scientists found that some PET water bottles contained trace amounts of chemicals that could mimic hormones if ingested. So while there is no documented proof that PET carpet fibers are bad for you, why risk it? Stay safe by keeping them out of your mouths and noses. Also, frequent vacuuming (once a week or more often) should help to contain the problem, and is recommended for general maintenance anyway.

Overall, PET carpet—which is indeed made from recycled soda and water bottles and is sold under the name brands Resistron and Permalon, among others—is a pretty green choice. Buildings in several national parks have used PET carpet in lobbies and other high-traffic areas with minimal need for maintenance and excellent results. PET fibers are naturally stain resistant and do not require the chemical treatments used on most nylon carpets, and they retain color and resist fading from exposure to the sun or harsh cleaning. PET carpet advocates report that because plastic beverage containers are made with top quality resins as required by the U.S. Food & Drug Administration, recycled PET is superior to lower grades of virgin synthetic fibers used in making other brands of polyester carpet yarns.

Also, old PET carpet can live another day when it is “down-cycled” for use in other applications such as car parts, insulation, and even furniture stuffing. PET carpet advocates brag that their products keep plastic soda and water bottles out of the landfill, but who knows how many of those sacrificed bottles could have lived on as more bottles instead of other end of the line products.

GreenAmerica, publisher of the popular yearly-published
National Green Pages, recommends the 100 percent post-consumer recycled PET carpets for sale on Liberty Carpet One’s GreenFloors.com website. Liberty Carpet One claims that every square yard of PET carpeting they sell keeps 40 water or soda bottles out of landfills. The company also reports that its dyeing method is less polluting and requires less energy to produce than other flooring options, and that all of their carpets have been tested and meet indoor air quality standards set by the U.S. Environmental Protection Agency.

Of course, if you’re starting from scratch, good old natural fibers such as wool, sisal, jute and seagrass may be the greenest and healthiest carpet choices out there, especially when paired with pads made from cotton or rag (not petroleum). Other than GreenFloors PET carpeting, GreenAmerica also vouches for natural fiber offerings from the likes of Contempo Floor Coverings and Natural Home. And besides carpeting, there is a whole world of harder flooring choices that meet environmentalists’ strict criteria, from sustainably harvested hard woods to bamboo to cork.

EarthTalk: Can You Recycle Plastic Sandwich Bags and Plastic Wrap?

EarthTalkPlasticWrap


Dear EarthTalk
: Where do you recycle plastic stuff like sandwich bags, Saran wrap and plastic grocery store wrappers? Can they just go in with other plastics in the recycling bin? There never seems to be any information available about this.  -- Renee La-Fountaine, Lake Hughes, CA

The reason you don’t hear much about recycling these types of plastic films is that most municipalities don’t take back items intended to wrap food. One exception may be sandwich bags, which are made from easy-to-recycle polyethylene, as long as any hard (i.e. “Ziploc”) components are removed and they are rinsed free of any food debris or stains.

For that matter, if you are going to the trouble to wash them, you may as well dry and reuse them at home a few times before relegating them to the recycling bin. There are even small countertop racks available for hanging plastic bags to dry before reusing them.

Clinging plastic like Saran wrap is problematic for recyclers because the resin that it contains (to give it wrapping power) cannot be re-extracted without massive amounts of energy—more than it takes to make it new from scratch. And given that it’s usually soiled with some kind of food, used plastic wrap should always just go right into the trash.

Other non-recyclable plastic films include dark-colored plastic bags, bags with handles or drawstrings, and anything else designed to be wrapped around food. Since you can’t even rinse or recycle these kinds of plastics, it’s better to avoid them altogether and invest in some reusable containers to store leftovers.

Another option is to use plastic grocery store shopping bags (though they are increasingly being phased out) to wrap your food leftovers in. Many municipalities and most stores that provide such bags accept them for recycling, so once you’re done with them they can be recycled or returned to the store, after which they can be melted down and incorporated into weather- and rot-resistant window and door frames, decking (such as Trex), palettes, pipes and other long-lasting hard goods. Like with sandwich and other bags you intend to recycle, make sure plastic grocery bags are clean before you turn them in for recycling.

If you are a Ziploc bag or plastic wrap fanatic but want to do the right thing by the environment, look for plastic food storage film or bags made from biodegradable polymers. Some popular brand names to keep an eye out for at Whole Foods and elsewhere are Eco Wrap, EcoFlex and BioBag. These plastics—some of which are made from agricultural scraps left over from corn crops—can go right in with yard waste or other compostables and will break down over time accordingly just like cardboard or food scraps. With time major brands will undoubtedly be offering similar products.

But even though there may in fact be “greener” plastic out there, reducing our reliance on disposable bags altogether should be the ultimate goal. Luckily many grocery chains are hip to greening their own operations and image, and are giving away or selling for a nominal amount reusable canvas shopping bags so customers don't have to choose between wasting plastic and paper at the checkout line.

EarthTalk: Spray Sunscreen Convenience Over Safety

EarthTalkSunscreen

Dear EarthTalk: Isn’t spray sunscreen a health and environmental nightmare when it seems that more of the sunscreen ends up going up my nose than on the kid at the beach next to me? -- Lillian Robertson, Methuen, MA


Spray cans of sunscreen may no longer contain chlorofluorocarbons (also known as CFCs, which were phased out in the 1990s for causing holes in the stratospheric ozone layer), but many contain other chemicals that are no good for our health or the environment. Researchers have found that the chemicals and/or minerals in the vast majority of commercially available sunscreens—even the rub-in creamy or oily varieties—can cause health problems just from ordinary use; inhaling them only magnifies the risks.

And just what are the risks? According to the non-profit Environmental Working Group (EWG), there are two major types of sunscreens available in the U.S. “Chemical” sunscreens, the more common kind, penetrate the skin and may disrupt the body’s endocrine system, as their active ingredients (e.g., octylmethylcinnamate, oxybenzone, avobenzone, benzophone, mexoryl, PABA or PARSOL 1789) mimic the body’s natural hormones and as such can essentially confuse the body’s systems. Quite a risk to take, considering that the chemical varieties don’t even work for very long once applied.

Meanwhile, “mineral” sunscreens are considered somewhat safer, as their active ingredients are natural elements such as zinc or titanium. But “micronized” or “nano-scale” particles of these minerals can get below the skin surface and cause allergic reactions and other problems for some people. EWG recommends sticking with “mineral” sunscreens whenever possible but, more important, taking other precautions to avoid prolonged sun exposure altogether. “At EWG we use sunscreens, but we look for shade, wear protective clothing, and avoid the noontime sun before we smear on the cream,” the group reports.

As for spray varieties, EWG recommends avoiding them entirely: “These ingredients are not meant to be inhaled into the lungs.” With so little known about the effects of sunscreen chemicals on the body when rubbed into the skin, we may never know how much worse the effects may be when they are inhaled. But suffice it to say: When your neighbor at the beach is spraying down Junior, it’s in your best interest to turn away and cover your nose and mouth.

The root of the problem, according to EWG, is failure on the part of the U.S. Food and Drug Administration (FDA), despite repeated requests from public health and consumer advocates, to implement sunscreen safety standards, some of which were proposed by government scientists more than three decades ago.

EWG only considers a small percentage of the sunscreens on the market—none of which come packaged in spray cans—safe for human use. Some of the top rated varieties come from manufacturers including All Terrain, Aubrey Organics, Badger, Blue Lizard, California Baby, La Roche-Posay, Purple Prairie Botanicals, thinksport, and UV Natural. None of the mainstream drug store variety brands appear on EWG’s recommended list. The full list is available on the sunscreens section of EWG’s Skin Deep website. With summer now upon us, stock up on good sunscreen before it’s too late.

EarthTalk: What's Green About Legal Weed?

EarthTalkMarijuana


Dear EarthTalk
: I heard someone say that legalizing pot—as Californians considered doing last year—would benefit the environment. How would that be? -
- William T., Portland, OR

It is well known that legalizing pot could have great economic benefits in California and elsewhere by allowing the government to tax it (like it now does on liquor and cigarettes), by ending expensive and ongoing operations to eradicate it, and by keeping millions of otherwise innocent and non-violent marijuana offenders out of already overburdened federal and state prisons. But what you might not know is that legalizing pot could also pay environmental dividends as well.

Nikki Gloudeman, a senior fellow at Mother Jones magazine, reports on the change.org website that the current system of growing pot—surreptitious growers illegally colonizing remote forest lands and moving pesticides, waste and irrigation tubes into otherwise pristine ecosystems—is nothing short of a toxic scourge. Legalizing pot, she says, would clean things up substantially, as the growing would both eliminate the strain on public lands and meet higher standards for the use and disposal of toxic substances.

Legalization would also reduce the environmental impacts of smuggling across the U.S./Mexico border, says Gloudeman: “Cartels routinely use generators, diesel storage tanks and animal poison to preserve their cache, when the border area is surrounded by more than 4 million acres of sensitive federal wilderness.”

Also, legalizing pot would move its production out into the open, literally, meaning that growers would no longer need to rack up huge energy costs to keep their illegal indoor growing operations lit up by artificial light. This means that the energy consumption and carbon footprint of marijuana growers would go way down, as the light the plants need for photosynthesis could be provided more naturally by the sun.

Yet another green benefit of legalizing marijuana would be an end to the destructive eradication efforts employed by law enforcement at bust sites, where the crop and the land they are rooted in are sometimes subjected to harsh chemical herbicides for expedited removal.

The legalization of pot in the U.S. would also likely open the door to the legal production of hemp, a variety of the same Cannabis plant that contains much lower amounts of the psychoactive drug, THC. Proponents say hemp could meet an increasingly larger percentage of our domestic fiber and fuel needs. Cannabis, the plant from which marijuana and hemp is derived, grows quickly without the need for excessive amounts of fertilizer or pesticide (it’s a “weed” after all) and absorbs carbon dioxide like any plant engaged in photosynthesis. The fiber and fuel derived from hemp would be carbon neutral and as such wouldn’t contribute to global warming—and in fact could help mitigate rising temperatures by replacing chemical-intensive crops like cotton and imported fossil fuels like oil and gas.

Of course, one might argue that the best thing for the environment would be to stop growing cannabis altogether. “But let’s be real: That’s never going to happen,” says Gloudeman. “In light of that, the next best bet is to make it legal.”

EarthTalk: Safe Options For Kids' Tattoos

EarthTalkTemporaryTattoos

Dear EarthTalk
: My daughter loves those press-on tattoos, and they’re frequently given out at birthday parties and other events. But I’ve noticed the labels say they’re only for ages three and up. Are they safe? If not, are there alternatives?
                                                -- Debra Jones, Lansing, MI

For the most part, so-called temporary tattoos are safe for kids and grown-ups alike, even if they do contain a long list of scary sounding ingredients including resins, polymers, varnishes and dyes. But if they are sold legitimately in the U.S., their ingredients have been approved by the U.S. Food and Drug Administration (FSA) as cosmetics, meaning the agency has found them to be safe for “direct dermal contact.” The FDA has received reports of minor skin irritation including redness and swelling, but such cases have been deemed “child specific” and were not widespread enough to warrant general warnings to the public.

Those who are concerned anyway but still want a temporary tattoo might consider an airbrush tattoo—they are sprayed on over a stencil using FDA-approved cosmetic inks. The rub on these in the past was that they didn’t last very long, but new varieties are reported to last two weeks, and can be easily removed prior to that with isopropyl alcohol, just like their “press-on” cousins.

Another alternative way to go is henna-based tattoos, which typically do not contain any additives whatsoever. Henna is a flowering plant used since the days of our earliest civilizations to dye skin, fingernails, hair, leather, and wool—and it makes for a relatively natural—although monotone—temporary tattoo.

But the FDA warns consumers to steer clear of any temporary tattoos labeled as “black henna” or “pre-mixed henna,” as these have been known to contain potentially harmful adulterants including silver nitrate, carmine, pyrogallol, disperse orange dye and chromium. Researchers have linked such ingredients to a range of health problems including allergic reactions, chronic inflammatory reactions, and late-onset allergic reactions to related clothing and hairdressing dyes. Neither black henna nor pre-mixed henna are approved for cosmetic use by the FDA and should be avoided even if they are for sale in a reputable store.

Something else to watch out for are the micro-injection machines used by some professional temporary tattoo artists such as might be hired for a corporate event or a festival  While getting a microinjection-based temporary tattoo may not hurt, it does puncture the skin. The United Kingdom’s Health and Safety Executive recently issued a warning that improperly cleaned machines could facilitate the spread of infectious diseases including HIV and hepatitis. As a result, several types of micro-injection machines with internal parts that could carry contamination from one customer to another have been banned there. Such machines aren’t as popular in the U.S., but if you aren’t sure, it’s best to avoid it. The more familiar press-on temporary tattoos are a safer bet regardless.

Just in case you’re worried that the FDA isn’t checking, the agency has in the recent past issued import blocks on temporary tattoos that do not comply with federal labeling regulations; buyers beware that the ones you get should clearly list their ingredients on the packaging per FDA requirements.
