(Beyond Pesticides, June 15, 2015) A community in central Michigan is still dealing with the fallout of a pesticide company that produced DDT nearly half a century ago. St. Louis, MI, a city about one hour north of the state capital Lansing, has long dealt with contamination left behind by the Velsicol Chemical Corporation, which manufactured pesticides in the town until 1963, when it left  and  abandoned loads of DDT in its wake. DDT, known for accumulating in food webs and persisting for decades in soil and river sediment, was banned in the U.S.  in 1972, but problems associated with its prevalent use until that time still plague the community to this day. This situation  has led to a multi-million dollar clean-up effort at taxpayers’ expense  by Environmental Protection Agency (EPA) and the Michigan Department of Environmental Quality (DEQ). EPA took control of the Velsicol plant as a Superfund site in 1982, but decades-long delays in the cleanup of the old chemical factory have left songbirds, and potentially people at risk nearly thirty years later. After years of complaints from residents, researchers  recently reported  that robins and other birds are dropping dead from DDT poisoning. The dead robins and other […]

(Beyond Pesticides June 4, 2015) Another study has found links between a commonly used household pesticide and attention deficit hyperactivity disorder (ADHD) in children and young teens. Researchers at Cincinnati Children’s Hospital Medical Center found an association between pyrethroid pesticide exposure and ADHD, particularly in terms of hyperactivity and impulsivity. These results reinforce the findings of a study led by a research team at Rutgers University earlier this year that found links between the pesticide deltamethrin and ADHD. In 2001, over concerns about adverse health consequences, the U.S.  Environmental Protection Agency banned several commonly used organophosphate (organic compounds containing phosphorus) pesticides from residential use due to the chemicals neurotoxic properties. The ban led to the increased use of pyrethroid pesticides, which are now the most commonly used pesticides for residential pest control and public health purposes. Pyrethroids, like deltamethrin, are commonly used in the home,  office buildings,  and on vegetable crops, gardens, lawns and golf courses. This shift to predominantly using pyrethroids is troubling, as they have oft been promoted as a safer choice than banned organophosphates, despite the fact that they pose many real threats to human health. Many recent studies show significant concern with this class of chemicals, […]

(Beyond Pesticides, May 21, 2015) The California Department of Pesticide Regulation (CDPR) published its Annual Pesticide Use Report last week, which finds that overall pesticide use for agricultural purposes has increased by 3.7 percent between 2012 and 2013. Pesticide use increased by 6.4 million pounds in 2013, the most recent data available, making for a grand total of 178 million pounds of pesticides used annually in California’s agricultural industry. The study also revealed several insights on trends in pesticide use, the most troubling of which is the increased use of organophosphates, and more specifically, the insecticide chlorpyrifos. This raises concerns that, absent aggressive efforts by CDPR to ban chlorpyrifos’ use in food production, industry reliance on the pesticide may continue to  increase. Chlorpyrifos was banned by the Environmental Protection Agency (EPA) for nearly all residential uses in 2000, but since then has remained widely available for agricultural use. Efforts to limit the agricultural use of chlorpyrifos in the state of California have been in the works since the fall of 2014, and a regulation Designating Chlorpyrifos as a Restricted Material was recently adopted by California’s DPR.  The new regulation classifies as  ”˜restrictive use’  all pesticide products containing the organophosphate  insecticide […]

(Beyond Pesticides, May 13, 2015) In a letter sent this week, two Montgomery County Councilmembers are requesting that hospitals in the county assume a leading role in increasing awareness of the health concerns regarding pesticides by voluntarily agreeing to eliminate their use on hospital grounds. The letter states that this step  would help to reduce pesticide exposure for some of the county’s most vulnerable residents, and would increase awareness in the  community of pesticides’  potential harmful effects. Currently, Montgomery County is considering a bill that would limit the non-essential pesticide use on county property. On Monday, Council President George Leventhal, who chairs the Council’s Health and Human Services Committee, and Councilmember Roger Berliner, who chairs the Council’s Transportation, Infrastructure, Energy and Environment Committee, wrote to the leaders of the five organizations that operate hospitals in Montgomery County and asked them to voluntarily stop using pesticides on the grounds of their respective facilities. The text of the letter can be found here. In Monday’s press releases from the their’ offices,  Councilmembers Leventhal and Berliner said, “We are writing today to ask that hospitals in our County assume a leading role in increasing awareness of the health concerns regarding pesticides by voluntarily […]

(Beyond Pesticides, April 1, 2015) According to a new study from Harvard University researchers, eating fruit and vegetables containing pesticide residues adversely affect men’s fertility, leading to fewer and poorer quality sperm. The study, published online in the journal,  Human Reproduction, adds to a growing body of research that finds pesticide exposures give rise to impaired reproductive function, including reduced sperm counts, sperm quality and reduced fertility in exposed men. The results of this study also underscore the importance of an organic diet in reducing pesticide exposures. The study, “Fruit and vegetable intake and their pesticide residues in relation to semen quality among men from a fertility clinic,” believed to be the first to  look into the consumption of fruits and vegetables with high levels of pesticide residue in relation to semen quality, and conducted by researchers at Harvard University’s TH Chan School of Public Health, found that men who ate the greatest amount of fruit and vegetables with high levels of pesticide residue had a 49% lower sperm count and a 32% fewer normally formed sperm than those who consumed the least. Jorge Chavarro, MD, assistant professor of nutrition and epidemiology and co-author of the study, said, “We found […]

(Beyond Pesticides, March 13, 2015) Exposure to endocrine (hormone) disrupting chemicals (EDC) results in approximately € 150 billion ($162 billion) in health care costs in the European Union each year, according to panels of scientists tasked by the EU Commission to study their impact. “The shocking thing is that the major component of that cost is related to the loss of brain function in the next generation,” Philippe Grandjean, M.D. of Harvard University, one of the report’s authors, told the Guardian. EDCs, contained in common household products such as detergents, disinfectants, furniture, plastics, and pesticides, interfere with the body’s hormone system either by mimicking naturally produced hormones, blocking hormone receptors in cells, or effecting the transport, synthesis, metabolism or excretion of hormones. These impacts can result in devastating effects on one’s health, including behavioral and learning disorders, such as Attention Deficit Hyperactivity Disorder (ADHD), birth defects, obesity, early puberty, infertility, cardiovascular disease, and childhood and adult cancers. Nearly 100 percent of people have detectable amounts of EDCs in their bodies, according to the introductory guide to EDCs published by the Endocrine Society and IPEN. “Our brains need particular hormones to develop normally —the thyroid hormone and sex hormones like testosterone […]

(Beyond Pesticides, February 5, 2015) A brewing  battle in the European Union (EU) over removing from the market  Endocrine Disrupting Chemicals (EDC)s has  heated up. An investigative report in  The Guardian  reveals that a European Union (EU) scientific paper, prepared to assist in the development of new mandatory EDC risk assessment standards, was never made public. According to the report, EU Commission sources say the release of the paper was quashed as a result of chemical industry pressure and political influence. At the core of the debate lies two EU regulations, one concerning biocidal products (EU 528/2012) and the second on “plant pest protectants” (EU 1107/2009). Both of these regulations required the EU Commission to produce draft measures concerning specific scientific criteria for the determination of endocrine disrupting properties by December 14, 2013. Under the regulations, chemicals within the biocidal and plant pest protectant categories that are  categorized as having endocrine disrupting properties that may cause adverse effects in humans would be prohibited from use in the market place. As noted in the purpose and subject matter of the biocidal regulations, “The purpose of [the] Regulation is to improve the functioning of the internal market through the harmonization of the […]

(Beyond Pesticides, January 30, 2015) Extensive exposure to common chemicals may be linked to an earlier start of menopause, according to a new study out of Washington University School of Medicine in St. Louis. Researchers of the study found that women whose bodies have high levels of these chemicals, including three pesticides, experience menopause two to four years earlier than women with lower levels of the chemicals. The pesticides found to have a significant correlation with an early start in menopause were p,p’-DDE (a metabolite of DDT), β-hexachlorocyclohexane (a byproduct of the production of lindane), and mirex. All three pesticides are organochlorine insecticides or their breakdown products that have been banned for use  in the U.S., but continue to persist in the environment and in the food chain. The study, Persistent Organic Pollutants and Early Menopause in U.S. Women, published this week in the journal PLoS ONE, investigates the link between levels in blood and urine of 111 endocrine-disrupting chemicals (EDCs), or chemicals that interfere with the body’s hormonal activity, and focused on known reproductive toxicants or persistent environmental contaminants. The findings suggest a significant association between 15 chemicals —nine polychlorinated biphenyls (PCBs, which are industrial products), three pesticides, two […]

(Beyond Pesticides, January 7, 2015) On Monday, the U.S. Environmental Protection Agency (EPA) released a revised human health assessment for the insecticide, chlorpyrifos, which finds risks to workers who mix, load and apply chlorpyrifos, and that the chemical has the potential to pose risks to drinking water in small watersheds. The assessment also notes that EPA will retain the 10X (10-fold) safety factor to protect children from all routes of exposures. EPA’s latest finding confirms long-standing scientific data that  has documented chlorpyrifos’ toxicity to humans and environmental contamination. However, despite these findings, EPA proposes to place additional restrictions on chlorpyrifos’ use, instead of a widespread ban. This latest assessment updates the June 2011 preliminary human health risk assessment, which was widely criticized by environmental and farmworker groups. EPA is releasing this assessment based on new information received since 2011, including public comments. The assessment is, in part, in response to a petition submitted by Natural Resources Defense Council (NRDC) and Pesticide Action Network (PAN) in 2007, which called on the agency to ban all uses of the insecticide. In 2000, EPA orchestrated a voluntary cancellation with the manufacturer Dow AgroSciences of  most residential uses of chlorpyrifos to limit children’s exposure, […]

(Beyond Pesticides, August 21, 2014) In case there wasn’t enough news about the hazards of the ubiquitous antibacterial chemical triclosan in the past week, another study published Tuesday finds additional risks associated with exposure to the pesticide. The study, Health Care Worker Exposures to the Antibacterial Agent Triclosan, led by researchers at University of California San Francisco (UCSF) finds that washing hands with antibacterial soap exposes hospital workers to significant and potentially unsafe levels of triclosan. In the study, published in the August issue of the Journal of Occupational and Environmental Medicine, researchers analyze urine samples from two groups of 38 doctors and nurses at two hospitals, identified as Hospital 1 and Hospital 2. Hospital 1 used an antibacterial soap containing 0.3 percent triclosan, while Hospital 2 used plain soap and water. Workers at Hospital 1 had significantly higher levels of triclosan in their urine than workers at Hospital 2. “Antimicrobial soaps can carry unknown risks, and triclosan is of particular concern,” said co-investigator Paul Blanc, MD, a professor of medicine at UCSF who holds the Endowed Chair in Occupational and Environmental Medicine. “Our study shows that people absorb this chemical at work and at home, depending on the products […]

(Beyond Pesticides, August 19, 2014) Newly released documents from the U.S. Food and Drug Administration (FDA) reveals that regulators expressed concerns over the safety of triclosan in Colgate Total toothpaste during the product’s registration in the mid-1990s. This information was provided to the public by FDA after a Freedom of Information Act request by the Natural Resources Defense Council (NRDC), and was posted on the agency’s website after inquiries from Bloomberg News. In addition to health effects previously identified by Beyond Pesticides, these documents raise concerns about the use of triclosan as an anti-gingivitis agent in toothpaste; a use which is not currently under scrutiny as FDA conducts its long-awaited health review of the chemical. Although FDA is requiring manufacturers of triclosan-containing soaps to prove that their products are not hazardous to humans and more effective than regular soap and water, triclosan formulated in toothpaste was not subject to a similar requirement as FDA had indicated that the chemical is effective as an anti-gingivitis agent. Colgate Total is the only brand of toothpaste on the market that still contains triclosan; GlaxoSmithKline, producer of Aquafresh and Sensodyne, removed triclosan from its toothpaste in 2009. And a focus on safer products seems […]

(Beyond Pesticides, August 8, 2014) Despite the continued documentation of weed resistance all over the United States, as well as the world, another line of herbicide-tolerant crops developed by Monsanto is currently in the pipeline awaiting likely approval by U.S. regulators. The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) released a draft environmental impact statement (EIS) on Tuesday, which, according to regulators, will pave the way for the approval of new  genetically modified cotton and soybean plants tolerant to a mixture of the herbicides glyphosate and dicamba. Monsanto’s new soybean and cotton crops were developed to withstand their new herbicide formulation, called Roundup Xtend, which combines the pesticides dicamba and glyphosate. The “Roundup Ready Xtend crop system” was developed to curb the proliferation of millions of acres of weeds that have grown resistant to Monsanto’s glyphosate-based Roundup, which has been used on the company’s biotech corn, soybeans, and cotton. Weed resistance due to cropping systems dependent on herbicides has been documented for years, making APHIS’ conclusions in the EIS all the more alarming. A report that Beyond Pesticides published 12 years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide […]

(Beyond Pesticides, August 7, 2014) Residents of St. Louis, Michigan aren’t used to seeing large excavators and dump trucks haul piles of dirt from their front yards or entire blocks of big, neighborhood trees felled. What they are used to seeing are dead birds ””sometimes even spontaneous, mid-flight deaths of the birds”” and because of a toxic series of events, disasters, and delays spanning decades, the two sights are inextricably connected. As one St. Louis resident described to the Detroit Free Press, dozens of dead robins and blackbirds had been collected from her backyard in the 18 years she has lived there, with the most recent just a couple weeks ago. This experience and other similar stories from the area prompted researchers at Michigan State University (MSU) to start figuratively and literally digging. Matt Zwiernik, Ph.D., an environmental toxicologist at MSU, and volunteers collected 29 dead birds, including 22 robins, last year from a nine-block residential area in St. Louis. The scientific sampling was only a small portion of the dead birds they could have collected, Dr. Zwiernik explained to reporters at the Detroit Free Press, as time, distance, logistics, and access to property sometimes limited collection efforts. Nevertheless, it […]

(Beyond Pesticides, July 21, 2014) According to figures released by the British Government last week, over 60% of the county’s bread supply is tainted with pesticide residues. This is a shocking increase from numbers recorded in 2001, which found 28% of bread to be tainted. According to the Department for Environment, Food and Rural Affairs (Defra) Expert Committee on Pesticides Residues in Food (PRIF), 2,951 bread samples were tested. According to a Pesticide Action Network UK report, a majority of the reoccurring pesticides were glyphosate and chlormequat. Glyphosate is an herbicide that can lead to non-Hodgkin’s Lymphoma, genetic damage, cancer, reproductive issues, liver damage, and endocrine disruption as well environmental damage such as water contamination and harmful effects to amphibians. Unfortunately, very little research has been done on what the effects can be on humans. Chlormequat, the second most-commonly found pesticide in British bread, is a plant growth regulator. A study conducted by the UN’s Food and Agriculture Organization (FAO) linked Chlormequat to developmental toxicity in animals. Very little research has been performed assessing the public health impact of this pesticide. In the U.S., it is only allowed for use on ornamental plants. Pan UK spokesman Nick Mole said, “The […]

(Beyond Pesticides, July 16, 2014) The Canadian Environmental Law Association (CELA) and Clean Production Action (CPA) released a comprehensive assessment of the hazards posed by triclosan and its chemical cousin triclocarbon Thursday, calling on the Canadian Government to create a comprehensive phase-out plan for these harmful antibacterial chemicals. The report, which finds that the chemicals are accumulating in the waters of the Great Lakes, also suggests that the U.S. and all provinces and states bordering the Great Lakes should prohibit use of the chemicals. The two antibacterial chemicals are commonly used in consumer products ranging from liquid soaps and toothpaste to kitchen cutting boards, and have come under increased scrutiny amidst human health concerns and lack of efficacy. The Canadian Medical Association (CMA) has been calling for a ban on the household use of triclosan since 2009, and in 2012, the Canadian government declared triclosan as toxic to the environment. In the U.S., Beyond Pesticides has petitioned the Food and Drug Administration (FDA) and its counterpart, the U.S. Environmental Protection Agency (EPA) (which regulates non-cosmetic products with triclosan) for years to immediately ban triclosan from consumer products, citing endocrine disruption, and other human health concerns. Last December,  FDA announced  it […]

(Beyond Pesticides, July 15, 2014) More nutritional antioxidants, far fewer toxic pesticides; those are the results of a comprehensive meta-analysis on organic foods published yesterday in the British Journal of Nutrition.  Led by Carlo Leifort, Ph.D, at England’s Newcastle University, the analysis is a scientific rebuttal to a previous Stanford University review published in 2012, which found that there was little difference between the nutritional content of organic food over conventionally grown produce. Both studies found there to be fewer pesticides in organic products. While Stanford University’s review only looked at 200 studies, Dr. Leifert and his team of researchers expanded the scope of their meta-analysis to 343 studies, and also employed more robust analytic tools by analyzing the standardized mean differences of the data from the various studies. It shows very clearly how you grow your food has an impact,” said Dr. Leifert to The New York Times. “If you buy organic fruits and vegetables, you can be sure you have, on average, a higher amount of antioxidants at the same calorie level.” Antioxidants, compounds such as phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanin, have been linked to lower risks of cancer and other diseases. For many, news […]

(Beyond Pesticides, July 2, 2014) According to a new study, few obstetricians offer their pregnant  patients advice on how to avoid environmental toxins that might harm their babies, even though doctors recognize that exposure to chemicals like pesticides, bisphenol-A (BPA), and metals can affect  a pregnancy. The study recommends that the medical community improve medical education and training, develop recommendations for prevention and less toxic alternatives, as well as lend support to policy change. The first of its kind study of prenatal counselling, published in the journal  PLOS ONE, Counseling Patients on Preventing Prenatal Environmental Exposures – A Mixed-Methods Study of Obstetricians, found that U.S. obstetricians and gynaecologists feel they lack the medical education and training, and evidence-based guidelines and tools for communicating potential environmental risks to patients. Exposure to environmental toxins, the researchers from the University of California, San Francisco (UCSF) found, is rarely discussed with pregnant patients, even though a national survey shows that 80 percent of physicians agree they should play a part in reducing patients’ exposure to toxins. But, of the 2,500 respondents, only one in five routinely asked  their  patients about these exposures, and just one in 15 said they received training on the harmful […]

(Beyond Pesticides, June 24, 2014) Research from the University of California, Davis CHARGE (Childhood Autism Risks from Genetics and the Environment) study finds that pregnant women who lived within a mile of agricultural fields treated with insecticides are more likely to have their child develop autism. The results of the CHARGE study, published in Environmental Health Perspectives, strengthens calls from public health and environmental groups urging regulators take a precautionary approach to agricultural chemicals and institute increased protections for those who live, work, or go to school near pesticide-treated fields. The CHARGE study looked at pregnant women’s addresses to determine their location relative to fields treated with pesticides. For women who lived less than one mile from crops sprayed with organophosphate insecticides during their pregnancy, researchers found the likelihood of their child being diagnosed with autism increased 60%. Women in the second trimester living near fields treated with chlorpyrifos, a widely used organophosphate insecticide banned for household use in 2001, are 3.3 times more likely to have their children diagnosed with autism. In response to a legal petition, the U.S. Environmental Protection Agency (EPA) in 2012 instituted risk mitigation measures for chlorpyrifos, including reduced application rates and no-spray buffer zones […]

(Beyond Pesticides, June 9, 2014) Triclosan, the antibacterial pesticide found in numerous hand soaps, toothpastes, and other cosmetics, has had a ubiquitous presence on the consumer market for over 30 years. But due to public pressure led by Beyond Pesticides, our allies, and concerned supporters, many manufacturers have been washing their hands of triclosan. Now after years of inaction, the U.S. Food and Drug Administration (FDA) is going to require data to support triclosan’s claims of being “safe and effective.” The time is now to let the agency know that triclosan is NOT safe or effective for human and environmental health. Raise your voice with a unique public comment to FDA! Use the sample letter below for guidance. Rising Evidence Against Safety Beyond Pesticides has generated extensive documentation  of the potential human and environmental health effects of triclosan and its cousin triclocarban. Studies show that triclosan can interfere with thyroid and estrogen hormones, and may promote the progression of cancer cells. This is alarming given that the CDC has found that 75% of the U.S. population contain triclosan in their bodies, even in breast milk, and at levels that are rising. Triclosan is an endocrine disruptor and has been shown […]

(Beyond Pesticides, June 5, 2014) Environmental advocacy groups filed an Administration Objection and a court appeal last week in order to challenge the Environmental Protection Agency’s (EPA) refusal to quickly correct errors in pesticide registrations and immediately implement measures to protect children from exposure to dangerous pesticides that drift from fields during and after application. EPA’s continued refusal to protect children’s health from pesticide drift is being criticized by numerous environmental, health, and farmworker advocacy groups. The groups, which include  United Farmworkers, Pineros y Campesinos Unidos del Noroeste, Pesticide Action Network of North America, Sea Mar Community Health Centers, California Rural Legal Assistance Foundation, Physicians for Social Responsibility, and Farm Labor Organizing Committee, originally filed a petition back in 2009 titled “Pesticides in the Air””Kids at Risk: Petition to EPA to Protect Children from Pesticide Drift (2009).” The petition asked that the agency properly comply with an existing law that requires EPA to protect children’s health from exposure to pesticides that drift from fields and orchards. After a more than four-year wait and a court appeal, EPA finally provided a response last March. These groups object to EPA’s recent response to their 2009 petition on the basis of two issues, […]

(Beyond Pesticides, March 21, 2014) Banned pesticides and flame retardants may be the cause of higher autistic behaviors for children who were exposed in utero, according to new research published last week in the journal Environmental Health Perspectives. Previous research has demonstrated that organochlorine chemicals are linked to learning problems, such as attention-deficit hyperactivity disorder (ADHD), especially in boys. This research is one of the first studies to evaluate their contribution to autistic behaviors. According to the study, Gestational Exposure to Endocrine-Disrupting Chemicals and Reciprocal Social, Repetitive, and Stereotypic Behaviors in 4- and 5-Year Old Children, children who were exposed to higher levels of brominated flame retardant PBDE-28 and trans-nonachlor, a component of the banned pesticide chlordane, scored higher in terms of autistic behavioral patterns as ranked by their mothers. In the study, researchers conducted a case-cohort study recruiting 175 pregnant women from seven prenatal clinics within the greater Cincinnati, Ohio region who provided urine and blood samples during pregnancy to measure the concentration of endocrine disrupting chemicals. On average, pregnant women had 44 suspected hormone disrupting chemicals. Five years later, when children had turned four or five, mothers were asked to rank their children’s behavior based on a series […]

(Beyond Pesticides, March 13, 2014) Part deux of a 2012 study finding that sperm counts in French men had decreased 30% over the past 16 years came to a second startling conclusion in a 2014 analysis: the cause for those dramatic decreases may be pesticides. 2012 Sperm-Count Study Published in the scientific journal Human Reproduction, the landmark 2012 study showed an alarming 30 percent decrease in sperm counts across France between 1989 and 2005. Because the data for the 2012 study were drawn from Fivnat ””a French assisted reproduction technology database”” researches made sure to limit analysis to 26,600 sperm samples from otherwise virile 35-year-old men whose partners’ fallopian tubes were either blocked or missing. This control was added to ensure that the each couple’s infertility was due to these latter problems and not a problem with the man’s sperm. Broken down, the 2012 studies identified a 1.9 percent continued annual dip in sperm concentration and also found that there was a significant 33.4% decrease in the percentage of normally formed sperm over the entire 16-year period. At the time of release, the 2012 study’s authors wrote: “To our knowledge, it is the first study concluding a severe and general […]

(Beyond Pesticides, December 20, 2013) The European Food Safety Authority (EFSA) announced on Tuesday that pesticides linked to honey bee deaths worldwide may also damage human nervous systems ””in particular the brain, and recommended that the European Commission lower the guidance levels of acceptable exposure until more research is conducted. This new determination heightens the call to ban the use of these toxic chemicals in the U.S., following the lead of the European Union (EU). EFSA found that two commonly used chemicals “may adversely affect the development of neurons and brain structure associated with functions such as learning and memory” particularly of children. The recommendation focuses on two chemicals ””acetamiprid and imidacloprid”” in a relatively new class of insecticide called neonicotinoids. Three chemicals in this class were recently placed under a two-year ban in the European Union (EU) for uses on flowering crops known to attract honey bees. The move stems from a recent review of research on rats which found, “Neonicotinoids may adversely affect human health, especially the developing brain.” Researchers who exposed newborn rats to one of these chemicals ””imidacloprid”” found they suffered brain shrinkage, fewer nerve signals controlling movement, and weight loss. Another study on rats found […]
