Tell Bath and Body Works to ‘Spread Love and Not Toxics’

(Beyond Pesticides, July 20, 2011) With flavors like “tangelo orange twist,” and “sugar lemon fizz,” popular body care chain, Bath and Body Works, has marketed an entire line of antibacterial body care products to teens and young adults. Unfortunately, these products contain the toxic hormone disruptor and water contaminant, triclosan, which could be hazardous to teenagers whose bodies are still developing. Join Beyond Pesticides, Center for Environmental Health, and The Campaign for Safe Cosmetics in asking Bath and Body Works to stop selling triclosan products that claim to “Spread Love, Not Germs.” The Bath and Body Works antibacterial line, which includes products with names like “Tangelo Orange Twist” and “Sugar Lemon Fizz,” is marketed to teenagers using the slogan “spread love, not germs.” Although not listed on their website, this antibacterial line and others sold by the company contain triclosan as their main germ fighting ingredient. Beyond Pesticides in 2004 began voicing concern about the dangers of triclosan and in 2009 and 2010, submitted petitions to the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA), calling for the removal of triclosan from consumer products. Since then many major companies are quietly and quickly removing triclosan […]

Bill Reintroduced to Regulate Chemicals in Cosmetic Products

(Beyond Pesticides, June 29, 2011) The Safe Cosmetics Act of 2011 was reintroduced last week in the House of Representatives aiming to grant the U.S. Food and Drug Administration (FDA) authority to regulate personal care products, including cosmetics, to ensure they are free of harmful ingredients before they hit the shelves. Cosmetics currently go unregulated and can contain harmful ingredients like triclosan, heavy metals, formaldehyde and others which expose consumers to numerous health threats. The cosmetic and personal care product industry is self-regulated. But the Safe Cosmetics Act of 2011 will, according to U.S. Representative Ed Markey, a lead sponsor on the bill, “close a gaping hole in the federal law that allows potentially toxic chemicals to remain in the cosmetics products consumers use every day. Reps. Jan Schakowsky of Illinois, Ed Markey of Massachusetts and Tammy Baldwin of Wisconsin offered the “Safe Cosmetics Act of 2011,” which would require companies to put all of a product’s ingredients on its label. It would also require the Department of Health and Human Services to conduct random annual tests of products for harmful substances and would force FDA to produce a list of ingredients that are prohibited from being used in cosmetics.

Groups Sue FDA to Restrict Antibiotics in Livestock Feed

(Beyond Pesticides, May 27, 2011) A coalition of environmental and public health groups filed a lawsuit yesterday against the federal Food and Drug Administration (FDA) to require the agency to enforce strict standards regarding the routine use of antibiotics in livestock feed. The suit, filed by the Natural Resources Defense Council, the Center for Science in the Public Interest, Food Animal Concerns Trust, Public Citizen, and the Union of Concerned Scientists, calls on FDA to implement regulations based on its own findings that the routine use of low doses of antibiotics in animal feed presents increased risk for the development of resistant bacteria. The non-therapeutic use of antibiotic drugs in animal feed presents a serious risk to public health due to the potential for bacteria to develop resistance to the drugs as a result of repeated low dose exposure. The rise of drug-resistant infections in humans has been linked to the overuse of antibiotics in animal feed since the early 1970s, but FDA has failed to meet its legal responsibility to address the mounting health threat posed by the practice, according to the groups’ suit. The coalition’s suit would also force the agency to respond to citizen petitions filed by […]

EPA Urged To Ban Toxic Antibacterial Chemical Linked to Hormone Disruption and Widespread Water Contamination, as Comment Period Closes

(Beyond Pesticides, April 13, 2010) In response to a petition submitted to the U.S. Environmental Protection Agency (EPA) calling for a ban on the non-medical uses of triclosan, Beyond Pesticides is again urging the agency to halt the use of the antibacterial triclosan in consumer products. Citing recent scientific evidence detailing hormone disruption, impaired fetal development, water and crop contamination, the petitioners state that given the emerging science and the violation of numerous environmental statues by triclosan’s use constitutes placing a ban on the chemical. In comments submitted in support of the petition, Beyond Pesticides state that such a dangerous chemical has no place on the consumer marketplace. “The nonmedical uses of triclosan are frivolous and dangerous, creating serious long-term health problems and environmental hazards associated with its continued use. EPA has a responsibility to ban consumer triclosan use in a marketplace where safer alternatives are available to manage bacteria” said Jay Feldman, executive director of Beyond Pesticides. Triclosan’s impact on the consumer market has been aided by a false public perception that antibacterial products are best to protect and safeguard against potential harmful bacteria. However, research into triclosan’s health and environmental impacts shows triclosan does more harm than good, […]

Study Documents Triclosan’s Failure To Kill Bacteria in Hospital Settings

(Beyond Pesticides, March 9, 2011) A recent study reports that the underlying cause of a fatal outbreak of P. aeruginosa in a hospital came from the contamination of triclosan soap dispensers, which acted as a continuous source of the bacterium. The contaminated triclosan soap infected the hands of health care workers and then patients, since triclosan is shown to have no effect on P. aeruginosa -a bacterium frequently associated with hospital-acquired infections. Authors of the study recommend alcohol-based sanitizers where appropriate, instead of triclosan soaps. The study, “Molecular Epidemiology of a Pseudomonas aeruginosa Hospital Outbreak Driven by a contaminated Disinfectant-Soap Dispenser,” published online in PLoS One, investigates a fatal epidemic of P. aeruginosa that occurred in a hematology unit in Italy. The researchers found that patients became indirectly infected (e.g., during central venous catheter handling through contaminated items) and the triclosan soap dispenser acted as a common continuous source of P. aeruginosa infection. Since P. aeruginosa is intrinsically not susceptible to triclosan, the use of triclosan-based disinfectant formulations should be avoided in those health care settings hosting patients at high risk of P. aeruginosa infection, the authors conclude. Immunocompromised patients, especially chemotherapy patients, are especially at risk. Soap dispensers in […]

Antibacterial Soap Suspected of Making Patients Sick

(Beyond Pesticides, February 22, 2011) After witnessing a patient’s condition improve upon discontinuing the use of antibacterial products containing the active ingredient triclosan, Gerard Guillory, M.D. of Denver, Colorado believes that several of his patients are experiencing health problems caused by daily exposure to the chemical. Dr. Guillory told local ABC 7 News: Denver Channel that he was treating his patient, Mary Lou Simanovich, for hyperthyroidism and asked her about antibacterial soap, which she had been using for years. After Ms. Simanovich stopped using soaps containing triclosan, both she and Dr. Guillory noticed improvements in her condition and overall health. “I feel better now. That’s all I can say and I think there’s an association,” said Ms. Simanovich to the Denver Channel. Antibacterial agents like triclosan, found in many antibacterial products, are linked to a host of adverse health and environmental effects including hormone disruption, possible impaired fetal development, and water and food contamination. Triclosan is an endocrine disruptor and has been shown to affect male and female reproductive hormones and is also shown to alter thyroid function. “My suspicion is that if it’s damaging the thyroid, it’s probably damaging other organs in the body,” said Dr. Guillory to the […]

Another Company Pulls Triclosan from Products; Public Comment Period Extended

(Beyond Pesticides, February 3, 2011) Following numerous developments on the antibacterial pesticide triclosan in consumer products over the last year, including several published studies highlighting the serious adverse effects of exposure, the submission of a federal petition calling for the ban of the chemical, and increased consumer awareness, experts are urging companies to take precautions and remove the ingredient from their products. Newest on the list of companies to remove triclosan is GlaxoSmithKline, which has removed the chemical from its Aquafresh and Sensodyne toothpastes, as well as its Corsodyl mouthwash. Recently Colgate-Palmolive, makers of Colgate Total and Softsoap antibacterial hand soaps, has removed triclosan from most of its products, excluding its Total brand toothpaste, a line that the company claims fights gingivitis. However, as Elizabeth Salter Green, director of ChemTrust, a UK-based health and environmental organization, says in Cosmetics Design: “If one eats the right foods and maintains correct dental hygiene, then triclosan, or other antibacterial agents are not needed.” Antibacterial Soap: Public Health Survey In response to a recent survey on antibacterial soap by the chemical industry, Beyond Pesticides has released its own survey questions about the health and environmental issues surrounding antibacterial cleansers and asks that you share […]

Multiple Chemicals, Including Triclosan, Found in Pregnant Women

(Beyond Pesticides, January, 19, 2011) A new study finds for the first time that the bodies of virtually all U.S. pregnant women, and possibly their unborn children, carry multiple chemicals, including some used in common products such as non-stick cookware, processed foods and personal care products. Median levels of the controversial chemical triclosan are found to be higher in pregnant women compared with nonpregnant women. This new data highlights the urgency needed to remove toxic chemicals like triclosan from consumer products. While the Centers for Disease Control (CDC) has published previous reports on chemical levels in the general population, this is the first study to look at a broad range of chemicals specifically in pregnant women. Entitled, “Environmental Chemicals in Pregnant Women in the US: NHANES 2003-2004,” the study analyzed biomonitoring data from the National Health and Nutritional Examination Survey (NHANES) to characterize both individual and multiple chemical exposures in U.S. pregnant women. Researchers analyzed the data for 163 chemicals and detected about three-quarters of them at varying levels in some or all of the women. They found almost all — 99 to 100 percent — of the pregnant women carry polychlorinated biphenyls (PCBs), organochlorine pesticides, perfluorinated compounds, phenols such […]

Under Growing Market Pressure, Company Pulls Triclosan from Products

(Beyond Pesticides, January 10, 2011) Since the submission of a federal petition last year calling for the ban of the antibacterial pesticide triclosan from consumer products, along with numerous published studies highlighting the serious adverse effects resulting from exposure, as well as increased consumer awareness, major companies are succumbing to public pressure to remove this chemical from their products. Recently Colgate-Palmolive, makers of Colgate Total and Softsoap antibacterial hand soaps, has removed triclosan from most of its products. Numerous developments last year, including the petition to ban triclosan submitted by Beyond Pesticides and Food and Water Watch along with over 80 environmental and public health groups, citing triclosan’s violation of numerous federal statues, as well as the increasing scientific data on triclosan’s hormone disrupting effects and long-term environmental contamination, have placed triclosan under media and congressional scrutiny. Companies are now quietly moving to remove triclosan from their products ahead of potential regulatory action and increasing consumer and retailer rejection. Colgate-Palmolive is reformulating its popular soap products to exclude triclosan. The orange-colored ”˜Ultra-Palmolive Antibacterial,’ the antibacterial dish-cleaning liquid will no longer contatin triclosan as its active ingredient and will no longer make the claim of being a “hand soap,” but will […]

EPA Cited for Ineffective Regulation of Antimicrobials

(Beyond Pesticides, January 7, 2011) The Office of the Inspector General (OIG) for the U.S. Environmental Protection Agency (EPA) has released a report criticizing the agency’s lack of regulation concerning antimicrobial products. Citing a number of failures, the report finds that the EPA’s Antimicrobial Testing Program (ATP) has been largely inadequate in testing products to ensure safety and efficacy, and has failed to remove products that did not meet program standards. This report is especially of concern because some antimicrobials, such as triclosan, are known to cause dangerous public health and environmental hazards. Triclosan is one of the most prevalent antibacterial compounds found in products ranging from soaps and toothpastes to fabrics and toys. Studies have increasingly linked triclosan (and its chemical cousin triclocarban), to a range of adverse health and environmental effects, from skin irritation, allergy susceptibility, bacterial, endocrine disruption and compounded antibiotic resistant, tainted water, and dioxin contamination to destruction of fragile aquatic ecosystems. Through ATP, antimicrobial products including hospital disinfectants and tuberculocides are meant to be tested to ensure that they meet health standards and that the claims on the product labels are accurate. However, OIG has found that “EPA’s implementation of the ATP has not delivered […]

EPA Publishes Petition to Ban Triclosan, Opens Public Comment

(Beyond Pesticides, December 10, 2010) Announcing a 60-day public comment period, the U.S. Environmental Protection Agency (EPA) yesterday published in the Federal Register a petition filed by 82 public health and environmental groups, led by Beyond Pesticides and Food and Water Watch, to ban the controversial antimicrobial/antibacterial pesticide triclosan, found in products from clothing to soaps, for non-medical use. The Federal Register notice (Petition for a Ban on Triclosan, 75 FR 76461, December 8, 2010) invites the public to comment until February 7, 2011 on the need to ban triclosan under numerous federal statutes. The petition, filed on January 14, 2010, identifies pervasive and widespread use of triclosan and a failure of EPA to: (i) address the impacts posed by triclosan’s degradation products on human health and the environment, (ii) conduct separate assessment for triclosan residues in contaminated drinking water and food, and (iii) evaluate concerns related to antibacterial resistance and endocrine disruption. The petition cites violations of numerous environmental statutes, including laws on pesticide registration, the Clean Water Act, Safe Drinking Water Act, and Endangered Species Act. It also documents that triclosan is no more effective than regular soap and water in removing germs and therefore creates an unnecessary […]

Triclosan Linked to Increased Risk of Allergies, BPA Linked to Immune Problems

(Beyond Pesticides, November 30, 2010) Young people who are overexposed to antibacterial soaps containing triclosan may suffer more allergies, and exposure to higher levels of Bisphenol A among adults may negatively influence the immune system, a new University of Michigan School of Public Health study finds. Triclosan is a chemical compound widely used in products such as antibacterial soaps, toothpaste, pens, diaper bags and medical devices. Bisphenol A (BPA) is found in many plastics and, for example, as a protective lining in food cans. Both of these chemicals are in a class of environmental toxicants called endocrine-disrupting compounds (EDCs), which are believed to negatively impact human health by mimicking or affecting hormones. Using data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES), U-M researchers compared urinary BPA and triclosan with cytomegalovirus (CMV) antibody levels and diagnosis of allergies or hay fever in a sample of U.S. adults and children over age 6. Allergy and hay fever diagnosis and CMV antibodies were used as two separate markers of immune alterations. The study, “The Impact of Bisphenol A and Triclosan on Immune Parameters in the US Population, NHANES 2003-2006,” was published online November 30, 2010 in the journal Environmental Health […]

Congresswoman Urges FDA to Ban Triclosan

(Beyond Pesticides, November 19, 2010) House Rules Committee Chairwoman Louise M. Slaughter and two colleagues asked the U.S. Food and Drug Administration (FDA) to ban triclosan due to the hazards that this chemical poses, including antibiotic resistance and potentially leading to higher health care costs, citing both Beyond Pesticides and Food and Water Watch along with other environmental groups. Rep. Slaughter, joined by Reps. Raul Grijalva and Betty McCollum, delivered the letter Tuesday, November 16, urging FDA to take immediate steps to stop the unnecessary exposure to this chemical in the U.S. Rep. Slaughter concludes that “triclosan is clearly a threat to our health.” Among the reasons for her conclusion, she lists: ”¢ The presence of triclosan in the human body and its impact on our “body burden;” ”¢ Bacterial resistance to antibiotic medications and antibacterial cleaners; ”¢ The potential for endocrine disruption as a result of triclosan bioaccumulation in the body; ”¢ Wastewater contamination; ”¢ The threat of destroying ecological balance, and; ”¢ The fact that triclosan is no more effective than soap and water. The scientific literature has extensivelly linked the non-medical uses of triclosan to many health and environmental hazards. Triclosan is an endocrine disruptor and has […]

Triclosan in Waterways Harmful to Important Microorganisms

(Beyond Pesticides, November 15, 2010) A new study suggests the widespread use of the antimicrobial triclosan may be inhibiting the aquatic bacteria and algae needed for a healthy ecosystem. Triclosan is an antibacterial compound found in a wide variety of household products including soaps, cosmetics, toothpaste, flooring, textiles, and even children’s toys. According to the study entitled “Triclosan persistence through wastewater treatment plants and its potential toxic effects on river biofilms,” when triclosan finds its way into rivers and streams it can inhibit photosynthesis in algae and kill bacteria. The study examined a group of algae known as diatoms. Through photosynthesis, diatoms produce food as well as oxygen needed for other organisms. Diatoms produce an estimated 80 percent of the oxygen in our atmosphere making them essential to life on earth. When introduced to the market in 1972, triclosan was confined to hospital and health care settings. Aided by the false public perception that antibacterial products are best to protect and safeguard against potential harmful bacteria, triclosan has since exploded in the marketplace in hundreds of consumer products ranging from antibacterial soaps, deodorants, toothpastes, cosmetics, fabrics, toys, and other household and personal care products. Due to the prevalence of this […]

Triclosan Exposure Raises Pregnancy Concerns

(Beyond Pesticides, November 10, 2010) A University of Florida, Gainesville study reports that the antibacterial pesticide triclosan, found in toothpaste, soaps, toys and clothing, interferes with estrogen metabolism in women and can disrupt a vital enzyme during pregnancy. These recent findings raise concerns about triclosan’s possible effects on fetal growth and development. This study is just one of an emerging body of science which supports triclosan as an endocrine disruptor and should be eliminated from consumer products. The study, which was published in the November print issue of the journal Environment International, examines the effect of triclosan on a placental enzyme, called estrogen sulfotransferase. Triclosan is known to inhibit sulfonation of phenolic xenobiotics and is structurally related to other known inhibitors of estrogen sulfotransferase, such as polychlorobiphenylols (PCBs). During pregnancy, the placenta is an important source of estrogen, which is needed for normal fetal development and successful parturition (childbirth), and estrogen sulfotransferase is thought to play an important role in regulation of estrogen availability. Estrogen is a key hormone during pregnancy and controls the way a baby develops many key organs like the brain. Triclosan was found to be a very potent inhibitor of both estradiol and estrone sulfonation. The […]

Antibacterial Soap Hit with Class Action Suit for False Anti-Germ Claims

(Beyond Pesticides, September 29, 2010) A class action complaint claims Dial Corp. defrauds consumers about its Dial Complete soap by falsely claiming that it ‘kills 99.99% of germs,’ when in fact the product provides no benefit over washing with regular soap and water. The suit states that Dial Corp.’s claims are deceptive and misleading, designed solely to cause consumers to buy the product. Dial Complete contains triclosan, a registered pesticide, which is linked to numerous adverse effects including hormone disruption and water contamination. The suit wants Dial Corp. enjoined from continuing its deceptive advertising, disgorgement and damages for consumer fraud and deceptive business practices. The plaintiff, David Walls, in his suit states there are no reliable studies that show Dial Complete lives up to these claims. His complaint states: “Through its extensive and comprehensive nationwide marketing campaign, defendant claims that Dial Complete ‘kills 99.99% of germs’, is the ‘#1 Doctor Recommended’ brand of antibacterial liquid hand wash and ‘kills more germs than any other liquid hand soap’, when in actuality, it does not, a fact which Dial knew and purposely misrepresented and failed to disclose to consumers. To this day, Dial has taken no meaningful steps to clear up consumer […]

Send Your Comments to EPA as Scientists Examine the Fate of Silver Nanoparticle Waste

(Beyond Pesticides, September 24, 2010) Researchers from Virginia Tech discovered, for the first time, a way to detect nanosilver particles in the environment, finding that the particles leaching from consumer products can transform into silver sulfide in sewer sludge. Despite their widespread use, scientists still know very little about how nanomaterials move from consumer manufactured products into the environment and what impact they might have. These findings provide new information about the life cycle of silver nanoparticles, which are used in a number of consumer products as antimicrobial agents, including cosmetics, sunscreens, sporting goods, clothing, electronics, baby and infant products, food, and food packaging. Previous studies have shown that the particles, which are between one and 100 nanometers in size and smaller than many viruses, can enter the environment through wastewater, where they can accumulate in biosolids at wastewater treatment plants. These biosolids, also known as sewage sludge, are often sold to consumers as fertilizer, despite the fact that they can contain toxic contaminants, including another antibacterial, triclosan, which was recently found to persist in the environment. Nanosized particles can be released from impregnated materials via washing or or as a result of sweating, posing unknown adverse effects to humans […]

Triclosan Persists at Low-Levels in the Environment for Long Periods of Time

(Beyond Pesticides, September 23, 2010) A study by U.S. Department of Agriculture (USDA) scientists and cooperators provides new details about how fertilizing soils with biosolids also introduces triclosan, an antibacterial agent in soaps and other cleaning supplies, into the environment. Results show that triclosan in biosolids is only slowly degraded and persists at low levels in the environment for long periods of time. Biosolids are illegal for use in organic agriculture. For this study, entitled “Fate of triclosan in agricultural soils after biosolid applications” and published in Chemosphere, Agricultural Research Service (ARS), chemist Clifford Rice, of the ARS Environmental Management and Byproduct Utilization Laboratory in Beltsville, Md., and his partners determined that triclosan levels in Class B biosolids from a Mid-Atlantic wastewater treatment plant averaged around 15.5 milligrams per kilogram. They collected surface soil samples from 26 farms in northern Virginia, mostly from pastures. Some fields had never been amended with biosolids and others had been amended with one to four applications of biosolids within the previous 9 months to 13 years. Most of the biosolid amendments came from the wastewater treatment plant in the study. Generally, conventional chemical-intensive farmers add “Class B” biosolids, also known as treated wastewater solids, […]

Nanosilver Particles Can Stop Sperm Cells from Growing

(Beyond Pesticides, September 3, 2010) New research shows that silver nanomaterials, which are used in a number of consumer products as antimicrobial agents, can interrupt important cell signaling within male reproductive sperm cells, causing them to stop growing. In previous studies, scientists reported how smaller-sized silver nanoparticles — in the 10 – 25 nanometer range — decrease the growth of male stem cells when they are exposed at concentrations greater than 10 micrograms per milliliter (μg/ml). This new study, on the other hand, is the first to identify how the silver nanoparticles stop the sperm stem cells from growing, with the biggest effects from the smallest-sized nanoparticles tested. Like many other studies on the effects of nanotechnology, this study raises important questions about the potential hazards to human health due to the prolific use of silver nanoparticles in the market. Researchers tested the effects of different sizes, concentrations and coatings of silver nanoparticles on cell growth of mouse sperm cells. They compared silver nanoparticles coated with either hydrocarbons — at 15 nm, 25 nm and 80 nm diameters — or sugars — at 10 nm, 25 – 30 nm and 80 nm diameter. Exposure to the smaller sized particles led […]

Antimicrobial Nanoparticles in Soil Can Harm Plants

(Beyond Pesticides, August 13, 2010) A new study finds that silver nanoparticles, which are used in consumer products and in hospitals for their antimicrobial properties, can harm plant life when it enters into the natural environment. Where silver nanoparticles are present in the soil, plant species are reduced by 22 percent, with an additional 20 percent reduction of microbial biomass, as compared to those plants without the presence of nanoparticles. Researchers applied biosolids with silver nanoparticles into the soil of plants growing in intermediate sized rubber tubs, using a concentration within the range that the U.S. Environmental Protection Agency (EPA) has reported finding in biosolids from a recent survey. “There have been a lot of lab studies looking at silver nanoparticles showing that they are highly toxic to bacteria, fungi, other microorganisms,” explained Ben Colman, PhD to Scientific American. Dr. Coleman is a postdoctoral researcher at Duke University who led the study. “Most of these studies have been conducted in very simple lab settings, [with] one species of bacteria””often the “lab rat” of the bacteria world, E [scherichia]. coli ””[in] a test tube with very simple media and nanoparticles. So we wanted to move beyond this because it’s really hard […]

Toxic Contaminants Found in City’s Free ‘Organic Biosolids Compost’

(Beyond Pesticides, August 11, 2010) Independent tests of sewage sludge-derived compost from the Synagro CVC plant -distributed free to gardeners since 2007 by the San Francisco Public Utilities Commission (PUC) in their “organic biosolids compost” giveaway program — have found appreciable concentrations of contaminants with endocrine-disruptive properties. These contaminants include polybrominated diphenyl ether (PBDE) flame retardants, nonylphenol detergent breakdown products, and the antibacterial agent triclosan. The independent tests were conducted for the Food Rights Network by Robert C. Hale, PhD of the Virginia Institute of Marine Sciences. The antibacterial triclosan, an endocrine disruptor, was also found in the sewage sludge compost, at an average of 1,312 ng/g (or ppb). Last week, the Centers for Disease Control updated their National Report on Human Exposure to Environmental Chemicals and noted that triclosan levels in people increased by over 41% between just the years 2004 and 2006. Also last week, a scientific paper showed that triclosan from sewage sludge can be taken up by soybean plants and translocated into the beans themselves, then consumed by people and animals. PBDEs are persistent and bioaccumulate in the environment and elevated levels have been found in California citizens. The average total of the PBDE congeners tested […]

New Data Shows Increased Triclosan Exposure

(Beyond Pesticides, August 9, 2010) Two separate findings that showcase increased exposure and potential for exposure in humans to the toxic chemical triclosan add to the mounting evidence that the non-medical use of this chemical should be banned. Newly released data from the Centers for Disease Control and Prevention (CDC) finds that levels of triclosan in humans have increased by 50% since 2004. Moreover, a study by the University of Toledo shows that triclosan and triclocarbon, a similar compound, can enter the food chain through use of contaminated water or fertilizer on agricultural crops. CDC’s updated National Report on Human Exposure to Environmental Chemicals finds that the 50% increase in levels of triclosan is across all demographics in the U.S. population. Data was collected on the concentration of triclosan in urine. Affluent people and those over the age of 20 have the highest concentrations of triclosan in their urine. The study released by the University of Toledo, “Uptake of Pharmaceutical and Personal Care Products by Soybean Plants from Soils Applied with Biosolids and Irrigated with Contaminated Water,” examines the potential for crops to take up contaminants such as triclosan from water or fertilizer. Conventional crops are often fertilized with sewage […]
