(Beyond Pesticides, August 17, 2009) The four-day testing period the U.S. Environmental Protection Agency (EPA) commonly uses to determine ”˜safe’ levels of pesticide exposure for humans and animals could fail to account for the long-term effects of toxic chemicals, University of Pittsburgh researchers report in the September edition of Environmental Toxicology and Chemistry. The team found that the highly toxic pesticide endosulfan, a neurotoxin banned in several nations but still used extensively in U.S. agriculture, can exhibit a “lag effect” with the fallout from exposure not surfacing until after direct contact has ended. The findings build on a 10-year effort by Rick Relyea, Ph.D., an associate professor of biological sciences in Pitt’s School of Arts and Sciences, to understand the potential links between the global decline in amphibians, routine pesticide use, and the possible threat to humans in the future. The team exposed nine species of frog and toad tadpoles to endosulfan levels “expected and found in nature” for the EPA’s required four-day period, then moved the tadpoles to clean water for an additional four days, Jones reported. Although endosulfan was ultimately toxic to all species, three species of tadpole showed no significant sensitivity to the chemical until after they […]

(Beyond Pesticides, August 13, 2009) The Alaska Department of Environmental Conservation is currently reviewing a request by the Alaska Railroad for permission to use the herbicide glyphosate along a 90 mile stretch of its track between Seward and Indian. The herbicide is set to be applied on Railroad operating property (rail yards, spurs, sidings, etc) and along the mainline and branch line right-of way for four feet out from both sides of the track in the summer of 2010. Despite the fact that previous requests have been met with opposition, the railroad states that its vegetation problem has gotten too out of hand for “so-called ”˜alternative methods.’” They also state that the Federal Railroad Administration, the railroad’s federal regulatory agency, will impose fines and operational restrictions such as reducing speeds or emergency closures of some sections of track if they aren’t cleared of the overgrown vegetation. Current methods of weed management utilized by the railroad are mechanized rail-based brushcutters, off-rail hydroaxing, wayside manual cutting. The extents to which these methods are used are unknown, however, and the railroad states that these are effective””but only within limited ranges. Beyond Pesticides has an entire factsheet on least toxic control of weeds which […]

(Beyond Pesticides, August 12, 2009) A new study examining the effects of the mosquito repellent DEET on insects, mice and human proteins reports that the chemical interferes with a prominent central nervous system enzyme. This effect is magnified when exposure to DEET is combined with exposure to certain other pesticides. Entitled, “Evidence for inhibition of cholinesterases in insect and mammalian nervous systems by the insect repellent deet,” and published in BioMed Central (BMC) Biology, the study utilized toxicological, biochemical and electrophysiological techniques to show that DEET is not simply a behavior-modifying chemical, but that it also inhibits cholinesterase activity in both insect and mammalian neuronal preparations. The researchers examined DEET’s effects on mosquitoes, cockroach nerves, mouse muscles, and enzymes purified from fruit flies and humans. Applications of DEET slowed or halted the actions of the enzyme acetylcholinesterase. This enzyme is crucial for regulating nerve impulses in both insects and mammals, and once its functions are disrupted, neuromuscular paralysis, leading to death by asphyxiation result. In humans, symptoms include headache, exhaustion and mental confusion together with blurred vision, salivation, chest tightness, and muscle twitching and abdominal cramps. The study also investigated the consequences of DEET interactions with carbamate insecticides on the […]

(Beyond Pesticides, August 11, 2009) Carrboro, NC, the site of Beyond Pesticides’ 27th National Pesticide Forum, is the latest town to join the list of states and communities employing goats for nontoxic weed control. Communities across the nation, from Maryland to Wyoming to California, are discovering that grazing goats is a great option for land that suffers from unwanted plants, low organic matter and soil compaction. Goats eat weeds, add fertilizer and aerate the soil with their hooves, all at the same time. The town of Carrboro hired Goat Patrol, a targeted grazing service based in the Research Triangle region of North Carolina, to control a poison ivy infestation in a town dog park. The company, which currently consists of 16 goats, is owned and operated by Alix Bowman. Ms. Bowman says the inspiration for the business was found knee deep in a patch of English Ivy, which she was struggling to remove to make way for a garden. “If only I had some goats,” she thought. Four months later, the business school graduate returned to her farming roots and started the Goat Patrol. The Carrboro Board of Aldermen adopted an integrated pest management policy to reduce the use of […]

(Beyond Pesticides, August 10, 2009) The multinational chemical company Bayer has stated that it will end distribution of the pesticide endosulfan in 2010, and to replace the toxic pesticide with safer alternatives. The decision follows an innovative action in 16 countries, led by Pants to Poverty, the organic and Fairtrade underwear company, and its coalition of partners including Pesticide Action Network, Fairtrade Alliance Kerala and Zameen Organic. In a letter addressed to Coalition Against Bayer Dangers, Bayer said: “We plan to stop the sale of the substance endosulfan by the end of 2010 in all the countries where it is still legally available.” The letter, signed by Bayer CropScience’s head of investor relations, Judith Nestmann, said endosulfan would be replaced by alternatives “with a significantly better risk profile”. Bayer’s decision comes after years of global campaigning by the PAN Network and its partners and allies against this persistent pesticide, which is linked to autism, birth defects and male reproductive harm, as well as deaths and acute injuries to farmers through direct contact. It is banned in over 60 countries including those in the European Union. In the United States endosulfan is used primarily on cotton in the state of California […]

(Beyond Pesticides, August 5, 2009) In a letter authored by Senator Mark Leno and Assemblymember Bill Monning, and signed by twenty-five state legislators, the signatories called on Governor Schwarzenegger to keep the controversial pesticide methyl iodide out of California’s strawberry fields. “We strongly believe that methyl iodide has no role to play in building a secure, viable and healthy agricultural economy in the 21st Century,” said authors Senator Leno and Assemblymember Monning. On August 19, the Assembly Labor and Employment Committee will meet to explore the approval of methyl iodide and the potential impact on workers. “While I am encouraged at the decision of DPR to pursue the external peer review and public testimony, I still believe it is imperative to devote a special informational hearing by the Assembly Labor and Employment Committee focused on worker health and safety issues related to the potential registration of Methyl Iodide,” said Assemblymember Monning. “We are pleased that this group of legislators is taking the lead to protect public health. The scientific review of methyl iodide is very important in this case because of the sheer number of hazards it poses–cancer, thyroid disease, miscarriages, and neurotoxicity. This highly politicized process needs a reality […]

(Beyond Pesticides, August 4, 2009) In July 2009, the House Rules Committee held a hearing on the Preservation of Antibiotics for Medical Treatment Act (PAMTA – H.R. 1549). The legislation introduced by Congresswoman Louise Slaughter (D-NY), is designed to preserve the effectiveness of antibiotics by phasing out the non-therapeutic use of medically important antibiotics in livestock. The bill does not restrict use of antibiotics to treat sick animals or to treat pets and other animals not used for food. “There is little doubt that antibiotic-resistant diseases are a growing public health menace,” said Rep. Slaughter, a microbiologist with a master’s degree in public health. “From peanut butter to spinach to hot dogs, we all want to make sure the food we feed our families is safe. My legislation will limit the use of antibiotics on our livestock to ensure that we are not inadvertently creating antibiotic- resistant diseases that we can’t fight with modern medicine.” Antibiotics are an indispensable part of modern medicine, protecting all of us from deadly infections. Unfortunately, over the past several years, the widespread practice of using antibiotics to promote livestock growth and compensate for unsanitary, crowded conditions has led to the emergence of antibiotic-resistant strains […]

(Beyond Pesticides, August 3, 2009) Sometimes you have to look a little deeper to find the truth, as is the case with the headlines over the past week regarding organic produce’s nutritional value. Last week the London School of Hygiene & Tropical Medicine (LSHTM) researchers announced the publication of their new study, “Nutritional quality of organic foods: a systematic review,” to be published in the September issue of The American Journal of Clinical Nutrition, which finds “no evidence that organically produced foods are nutritionally superior to conventionally produced foodstuffs.” Organic advocates and consumers say the study and the press announcement fail at providing all the facts and are misleading in guiding people away from all the benefits organic products provide. “Unfortunately, it failed to include contemporary research showing organic strengths, and dismisses areas of organic superiority within its reviewed work, including antioxidant capacity (important for cancer-fighting properties),” states Timothy LaSalle, CEO of the Rodale Institute in the Huffington Post. “The study appears to say absolutely nothing negative about organics, despite valiant attempts by the media to create sensational headlines.” Over 50,000 papers were searched, and a total of 162 relevant articles were identified that were published over a fifty-year period […]

(Beyond Pesticides, July 30, 2009) A new report from the Institute of Medicine (IOM) and sponsored by the U.S. Department of Veterans Affairs finds suggestive but limited evidence that exposure to Agent Orange and other herbicides used during the Vietnam War is associated with an increased chance of developing ischemic heart disease and Parkinson’s disease in Vietnam veterans. The report is the latest in a congressionally mandated series by IOM that every two years reviews the evidence about the health effects of these herbicides and a type of dioxin – TCDD – that contaminated some of the defoliants. A finding of “limited or suggestive evidence of an association” means that the evidence indicates there could be a link between exposure to a chemical and increased risk for a particular health effect, though conflicting results from studies, problems with how the studies were conducted, or other confounding factors limit the certainty of the evidence. Until now, the cumulative evidence had been inadequate to draw conclusions about whether these two conditions may be associated with veterans’ exposures to herbicides or TCDD. Ischemic heart disease – a condition characterized by reduced blood supply to the heart, which can lead to heart attack and […]

(Beyond Pesticides, July 29, 2009) A new study by researchers at the Lombardi Comprehensive Cancer Center at Georgetown University finds a higher level of common household pesticides in the urine of children with acute lymphoblastic leukemia (ALL), a cancer that develops most commonly between three and seven years of age. The findings are published in the August issue of the journal Therapeutic Drug Monitoring. Researchers, in the study entitled, “Pediatric Acute Lymphoblastic Leukemia and Exposure to Pesticides,” caution that these findings, which do not establish a cause-and-effect relationship, suggest an association between pesticide exposure and development of childhood ALL. “In our study, we compared urine samples from children with ALL and their mothers with healthy children and their moms. We found elevated levels of common household pesticides more often in the mother-child pairs affected by cancer,” says the study’s lead investigator, Offie Soldin, Ph.D., an epidemiologist at Lombardi. Dr. Soldin cautions, “We shouldn’t assume that pesticides caused these cancers, but our findings certainly support the need for more robust research in this area.” Previous studies have found that exposures to certain pesticides increases the risk of developing certain cancers and degenerative diseases. The study was conducted between January 2005 and […]

(Beyond Pesticides, July 28, 2009) A new study by researchers at the National Food Institute, Technical University of Denmark shows that exposure to a mixture of pesticides and other chemicals has a synergistic effect on the development of male sex organs. Synergy occurs when the effect of multiple chemicals is greater than the sum of the individual effects. The study, “Synergistic Disruption of External Male Sex Organ Development by a Mixture of Four Antiandrogens,” was published July 15, 2009 in the online edition of Environmental Health Perspectives. The researchers designed their study to determine the consequences of simultaneous exposure to multiple “antiandrogens.” An antiandrogen, or androgen antagonist, is any of a group of hormone receptor antagonist compounds that are capable of preventing or inhibiting the biologic effects of androgens, male sex hormones, on normally responsive tissues in the body. Disrupting the action of androgens during gestation, certain chemicals present in food, consumer products and the environment can induce irreversible malformations of sex organs among male offspring. The team investigated the effects of mixtures of a widely used plasticizer, di(2-ethylhexyl) phthalate (DEHP), used in medical devices such as IV bags and tubing, beauty products, PVC toys, vinyl shower curtains, car seats, […]

(Beyond Pesticides, July 27, 2009) A mother’s exposure to urban air pollutants known as polycyclic aromatic hydrocarbons (PAHs) can adversely affect a child’s intelligence quotient or IQ, according to the new study “Prenatal Airborne Polycyclic Aromatic Hydrocarbon Exposure and Child IQ at Age 5 Years.” PAHs are widespread in urban environments and throughout the world as they have many sources, several of which are related to pesticides, including creosote used for wood preservation, burning pesticide-laden grass seed fields, and exposure to organochlorine pesticides whether banned, yet ubiquitous DDT or the still used insecticide dicofol. Other sources include synthetic turf fields and the burning of coal, diesel, oil and gas, or other organic substances such as tobacco. PAHs have been known to be bioaccumulative, carcinogenic and disrupt the endocrine system. The new study, funded by the National Institute of Environmental Health Sciences (NIEHS), a branch of the National Institutes of Health, the U.S. Environmental Protection Agency and several private foundations, found that children exposed to high levels of PAHs in New York City had full scale and verbal IQ scores that were 4.31 and 4.67 points lower than those of less exposed children. High PAH levels were defined as above the […]

(Beyond Pesticides, July 24, 2009) Whole Foods Market, a leading natural and organic grocery chain, recently announced a commitment to the Non-GMO Project, a non-profit collaboration of manufacturers, retailers, processors, distributors, farmers, seed breeders and consumers, to use the Non-GMO Project’s Product Verification Program (PVP) in connection with Whole Foods Market’s private label products. The 365 Every Day Value and Whole Foods Market brands will be enrolled in the program, with the first products arriving on shelves this Fall. While Federal law requires organic producers to comply with certain non-genetically engineered (GE) requirements identified in the USDA organic standards, there is no standard for labeling them in non-organic products. The PVP is the first system in the U.S.designed to scientifically test whether a product has met a set of defined standards for the presence of GE organisms (also known as GMOs, or genetically modified organisms). “From the moment GMOs were approved for use in the U.S., we recognized the need for transparency, but there was no definitive standard by which to evaluate or label products,” said Margaret Wittenberg, Whole Foods Market global vice president of quality standards. “We searched high and low for years for a way to do this […]

(Beyond Pesticides, July 23, 2009) A new study published in the August 2009 issue of Environmental Toxicology and Chemistry found that insecticides used in highly populated agricultural areas of California’s Central Valley affect amphibians that breed in the Sierra Nevada Mountains to the east. This study adds to the increasing evidence that pesticides impact areas and wildlife species that are miles from sources of pesticide application. Researchers from the Cooperative Wildlife Research Laboratory, Southern Illinois University and U.S. Geological Survey (USGS) examined the chronic toxicity of two of the insecticides most commonly used in the Central Valley- chlorpyrifos and endosulfan, to larval Pacific treefrogs (Pseudacris regilla) and foothill yellow-legged frogs (Rana boylii), the amphibians with declining populations that live and breed in meadows surrounding the Sierra Nevada. The results are discussed in “Toxicity of Two Insecticides to California, USA, Anurans and Its Relevance to Declining Amphibian Populations.” The study used laboratory testing to examine how the insecticides affected the two frogs at environmentally realistic concentrations. During testing, tadpoles were observed at various stages of development to see how the insecticides affected their growth and health. The researchers found that endosulfan was more toxic than chlorpyrifos to both species, and tadpoles […]

(Beyond Pesticides, July 22, 2009) The Oregon Department of Agriculture (ODA) recently released statistics for statewide pesticide use in 2008, while at the same time announcing the suspension of the reporting system, which has only been collecting data since 2007. The Pesticide Use Reporting System (PURS) was suspended until 2013 by House Bill 2999, due to lack of funding. The $800,000 saved will instead be used to fund two investigator positions. Until its reinstatement, officials will be unable to collect data or pursue enforcement related to missing reports from earlier in 2009. The 2008 PURS report documents agricultural and household pesticide use, which totaled almost 20,000 pounds and 572 different active ingredients. The top five active ingredients, by pounds, were all used in agriculture: metam sodium, glyphosate, 1,3-dichloropropene, sulfuric acid, and aliphatic petroleum hydrocarbons. Agriculture totaled 77 percent of all pesticide use, with urban/general indoor and outdoor uses totaling under four percent. The total used dropped by half from 2007, due in part to improved record keeping and a decline in the use of metam sodium, a popular fumigant in potato production. In households, pesticide use may be shifting away from the most toxic products. “In 2007, everyone was just […]

(Beyond Pesticides, July 20, 2009) Public health and environmental advocates have asked the U.S. Environmental Protection Agency (EPA) to deny a request from Dow AgroSciences for a permit allowing it to release large amounts of sulfuryl fluoride, a toxic pesticide whose global warming effects are thousands of times stronger than carbon dioxide, onto farm fields in four states. Dow AgroSciences proposes using sulfuryl fluoride to sterilize soil in farm fields. The permit would allow the release of 32,435 pounds of sulfuryl fluoride on 65 acres of test plots in Florida, Georgia, Texas, and California. Yet, researchers have found that sulfuryl fluoride stays in the atmosphere at least 30-40 years and perhaps as long as 100 years and is about 4,000 times more efficient than carbon dioxide at trapping heat. Because of the aggregate effects of surfuryl fluoride, Beyond Pesticides jonined Fluroide Action Network and Envirornmental Working Group in petitioning the U.S. Environmental Protection Agency (EPA) to cancel the registration of the chemical due to dangerous levels in food and water. “The hazards of using sulfuryl fluoride in agriculture have not been evaluated,” said Brian Hill, Ph.D., a staff scientist at the Pesticide Action Network. Releasing just 10 percent of the […]

(Beyond Pesticides, July 16, 2009) The U.S. Environmental Protection Agency (EPA) has issued a Final Work Plan (FWP) for the registration review of imidacloprid. A neonicotinoid insecticide, imidacloprid is highly toxic to honeybees on an acute exposure basis, and has been implicated in the recent Colony Collapse Disorder (CCD) that has occurred throughout the U.S. Over 12,000 comments were received by the agency since December 2008, urging the agency to suspend the use of this controversial chemical. Imidacloprid was first registered in the U.S. in 1994 as an insecticide to control a range of pests on crops, structures, indoor and outdoor residential areas, as well as pet products. While the use of imidacloprid has been gaining in popularity, its health and environmental effects have not been adequately studied. EPA, with its registration review program, pursuant to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) section 3(g), must review each registered pesticide every 15 years to determine whether it continues to meet the FIFRA standard for registration. The public docket for imidacloprid was opened in December 2008 and has since received over 12,000 comments, including those submitted by Beyond Pesticides, NRDC, the National Honey Bee Advisory Board (NHBAB) and Sierra Club, […]

On July 14, 2009, Beyond Pesticides and Food and Water Watch submitted an amended petition to the United States Food and Drug Administration (FDA) requiring that the agency ban the use of the controversial pesticide triclosan for non-medical applications on the basis that those uses violate the Federal Food, Drug and Cosmetics Act. Strong scientific evidence suggests that pervasive use of triclosan poses imminent threats to human health and the environment. “Numerous scientific studies and reports clearly indicate that in addition to its human health and environmental dangers, triclosan is not effective for many of its intended benefits and may actually be doing consumers more harm than good,” said Wenonah Hauter, executive director of Food & Water Watch. “Even worse, is that current regulations on triclosan haven’t been updated since 1994 and much of the science used by the FDA to regulate the pesticide dates back to the late 1970s and early 1980s. The agency’s inconsideration of new scientific research on triclosan represents an egregious failure to properly protect the public against this dangerous pesticide.” Regulated by both the FDA and the United States Environmental Protection Agency (EPA), triclosan is commonly found in hand soaps, toothpastes, deodorants, laundry detergents, fabric […]

(Beyond Pesticides, July 13, 2009) With the stroke of a pen, Governor Arnold Schwarzenegger could bow to industry interests and force the California Department of Pesticide Regulation to register a new fumigant pesticide, methyl iodide. Highly toxic, and not approved for use in California, this chemical has been given a comprehensive review by the state’s own Department of Pesticide Regulation (DPR) and found to be one of the riskiest pesticides in existence. Scientists familiar with methyl iodide are asking Mr. Schwarzenegger to let science, rather than political pressure, guide this decision. “Methyl iodide is so toxic that scientists working with it in the laboratory take extreme precautions when handling it, using a ventilation hood, gloves, and special equipment for transferring it so it does not escape to the air,” notes Susan Kegley, Ph.D., a chemist and consulting scientist for Pesticide Action Network North America. “This degree of protection is not possible in an agricultural setting where the pesticide would be applied at rates of 175 pounds per acre in the open air. Buffer zones of 400 feet (a distance most growers would say is unworkable) for a 40-acre fumigation would still result in a dose of methyl iodide to neighbors […]

(Beyond Pesticides, July 8, 2009) Pesticide campaigner Georgina Downs’ high court victory last November, when a court ruled that there was “solid evidence” that rural residents had suffered harm from crop spraying with toxic chemicals, was overturned yesterday by the Court of Appeal. Three judges on the Court of Appeal concluded that the government has complied with its obligations under European law and that it followed guidance that gave priority to human health. The agriculture industry hailed the ruling as a victory for “common sense.” Georgina Downs, who lives on the edge of farmland, launched a campaign in 2001 against the Department of the Environment, Food and Rural Affairs (DEFRA), documenting and collected evidence from other rural residents reporting health problems including cancer, Parkinson’s disease and asthma believed to be linked to crop spraying. Last November, Justice Collins said there was “a very strong case for a buffer zone” between spraying and human habitation. He ruled that the government had failed to comply with a European directive to protect people from the possible harmful effects of exposure to toxic chemicals. DEFRA challenged the ruling and yesterday the Court of Appeal overturned Justice Collins’ decision. The three judges on the Court […]

(Beyond Pesticides, July 6, 2009) Last week, the U.S. Environmental Protection Agency (EPA) proposed to formally evaluate the harmful effects of 74 pesticides on 11 endangered and threatened species in the San Francisco Bay Area over the next five years, and to impose interim restrictions on use of these pesticides in and adjacent to endangered species habitats. The proposal stems from a settlement agreement with the Center for Biological Diversity, which sued EPA in 2007 for violating the Endangered Species Act by registering and allowing the use of toxic pesticides in Bay Area endangered species habitats without determining whether the chemicals jeopardize those species’ existence. “Tens of millions of pounds of toxic and poisonous chemicals, known to be deadly to endangered species and harmful to human health, including proven carcinogens and endocrine disruptors, are applied in the Bay Area each year, and many of those find their way through runoff or drift into our soil, creeks and rivers, San Francisco Bay, and sensitive wildlife habitats,” said Jeff Miller, conservation advocate with the Center. “The toxic stew of pesticides in the Bay-Delta has played a major role in the collapse of native fish populations, and pesticides are a leading cause of […]

(Beyond Pesticides, June 30, 2009) How much do we know about the food we buy at our local supermarkets and serve to our families? In Food, Inc., producer-director Robert Kenner and investigative authors Eric Schlosser (Fast Food Nation) and Michael Pollan (The Omnivore’s Dilemma) lift the veil on the U.S. food industry — an industry that has often put profit ahead of consumer health, the livelihoods of American farmers, the safety of workers, and our own environment. The movie reveals how a handful of corporations control our nation’s food supply. Though the companies try to maintain the myth that our food still comes from farms with red barns and white picket fences, our food is actually raised on massive “factory farms” and processed in mega industrial plants. The animals grow fatter faster and are designed to fit the machines that slaughter them. Tomatoes are bred to be shipped without bruising and to stay edible for months. The system is highly productive, and Americans are spending less on food than ever before. But, the film asks, at what cost? Cattle are given feed that their bodies are not biologically designed to digest, resulting in new strains of E. coli bacteria, which […]

(Beyond Pesticides, June 23, 2009) According to a study published in the August-September 2009 issue of the journal Environmental Pollution, the presence of triclosan, a widely-used antibacterial pesticide found in products from countertops to toothpaste, was detected in the in the blood of bottlenose dolphins. The study, “Occurrence of triclosan in plasma of wild Atlantic bottlenose dolphins and in their environment,” was the first to find triclosan in the blood of a marine mammal, suggesting that contamination from sewage systems is widespread. According to a synopsis by Environmental Health News, the study examined dolphins from rivers, an estuary, a harbor and a lagoon in South Carolina and Florida. In this study, wild bottlenose dolphins were live captured from several sites within an estuary in Charleston, SC and in the Indian River Lagoon, FL in 2005. Blood samples taken from 13 animals in each area revealed triclosan in 31 and 23 percent of the animals from the two sites, respectively, at levels ranging from 0.025 to 0.27 parts per billion. These levels are similar to what has been measured in the blood of humans. When introduced to the market in 1972, triclosan was confined to hospital and health care settings. Since […]
