(Beyond Pesticides, May 30, 2008) A recent study has linked the common herbicide atrazine with endocrine disruption in both fish and human cells. Entitled “The Herbicide Atrazine Activates Endocrine Gene Networks via Non-Steroidal NR5A Nuclear Receptors in Fish and Mammalian Cells,” the University of Califonia, San Francisco (UCSF) research examines the reaction of zebrafish to environmentally relevant levels of atrazine, and mirrors the study in human placental cells. The zebrafish, which are particularly sensitive to endocrine disruptors,  are “feminized”  in greater proportion than the unexposed control group. Fish exposed to atrazine for 48 hours at levels found in agricultural runoff produced twice as many female fish as male. “These fish are very sensitive to endocrine disrupting chemicals, so one might think of them as ‘sentinels’ to potential developmental dangers in humans,” said senior author Holly Ingraham, PhD. “These atrazine-sensitive genes are central to normal reproduction and are found in steroid producing tissues. You have to wonder about the long-term effects of exposing the rapidly developing fetus to atrazine or other endocrine disruptors.” In human cell studies, the researchers found that atrazine activates genes involved in hormone signally and steroid synthesis. “Endocrine-related cell types with a capacity for steroid generation appear […]

(Beyond Pesticides, May 29, 2008) A study published in the May issue of Environmental Health Perspectives shows a link between prenatal exposure to the pesticide DDT and poor attention-related skills in early infancy. This study follows in a long line of recent studies associated with the negative health effects of DDT including: diabetes; non-Hodgkin lymphoma; breast cancer; and autism. Despite the fact that DDT was banned in the U.S. in 1972, concentrations of this toxic chemical’s major metabolite, DDE, have remained alarmingly high in many ecosystems, including the waters of Los Angeles County, the arctic, and even U.S. national parks. All studies documenting the health effects of DDT and chemicals in the same family, organochlorines, are particularly important not just for understanding the lingering effects of DDT from days past, but because many countries continue to employ DDT as a method in controlling mosquitoes that transmit malaria, despite its toxicity, weakening efficacy, and availability of safer alternatives. Other organochlorines are still registered for use in the U.S.The study looked at 788 mother-infant pairs who met several criteria, which included living in a town adjacent to a Superfund site in New Bedford, Massachusetts, a location with known organochlorine contamination. Cord blood […]

(Beyond Pesticides, May 28, 2008) Researchers have begun preliminary work to find suitable and safe alternatives to the widely used mosquito repellent DEET. Several possibilities have been identified, which repel mosquitoes for longer periods of time, but their safety for use on humans still needs to be investigated.Researchers, with funding from the Department of Defense, set out to determine what makes insect repellents work, and then to use that information in finding more effective ways to chase away disease-carrying insects. Insect repellents are used to repel biting insects such as mosquitoes and ticks that spread diseases such as encephalitis, Lyme disease, Rocky Mountain spotted fever, malaria and dengue fever. Ulrich R. Bernier, PhD, co-author of this study published online in the Proceedings of the National Academy of Sciences http://www.pnas.org/ and research chemist at the Agriculture Department’s mosquito and fly research unit in Gainesville, Fla., remarked that several of the new chemicals reviewed were “just phenomenal.” Using previous USDA data on hundreds of chemicals collected over 50 years, the researchers rated chemicals from “1” to “5” on ability to repel insects, and then focused on what the most effective ones ”” the 5s ”” had in common. They were able to […]

(Beyond Pesticides, May 27, 2008) A population-based study looking at how genes and environmental factors interact shows that pet shampoos containing insecticides may trigger autism spectrum disorders (ASD), reports New Scientist. The study findings, presented at the International Meeting for Autism Research, show that mothers of children with an ASD are twice as likely to have used an insecticidal pet shampoo during the prenatal and/or postnatal period when compared to mothers of healthy children. The strongest association was during the second trimester of pregnancy. According to the researchers, pet shampoos often contain pyrethrins and previous animal research has found that pyrethrins are designed to target the central nervous system in insects, rodents and other species and can cause death of neurons and compromise the blood-brain barrier in early life.Examining participants in the Childhood Autism Risks from Genetics and the Environment (CHARGE) study, researchers from the University of California, Davis looked at 333 children with ASD and 198 healthy children between the ages of two and five, and their families. In-depth questionnaires and blood and urine samples were collected. Isaac Pessah, Ph.D., a researcher involved in the study and professor in the Department of Molecular Biosciences, College of Veterinary Medicine at […]

(Beyond Pesticides, May 23, 2008) In the midst of dramatically declining bee populations, the German Office for Consumer Protection and Food Safety (BVD) has suspended the approval of eight toxic insecticides believed to be responsible for the fate of these important pollinators. The suspended products include pesticides containing imidacloprid and clothianidin, the majority of which are produced by Bayer Company and have been suspected for years of contributing to declining bee populations.France banned the use of imidacloprid on corn and sunflowers in 1999, and rejected Bayer’s application for clothianidin this year. Despite the call for prohibition of imidacloprid from German apiarists and environmental groups as early as 2004, a crisis in bee populations–a reported 50-60% loss, finally forced the government to take action. The U.S., where these products are still approved for use, has also been experiencing extremely alarming rates of bee colony collapse, while areas away from cropland have thriving bee populations. Imidacloprid and clothianidin are both neonicotinoids, meaning that they target nerve cells in a similar way to nicotine, acting as neurotoxins to sucking insects such as beetles and aphids. Clothianidin was approved for use in the U.S. in 2003 as a seed treatment for corn and canola, […]

(Beyond Pesticides, May 22, 2008) Before the U.S. Department of Agriculture (USDA) yesterday released its scaled-back annual report on 2007 pesticide use in U.S. agriculture, a coalition of 44 environmental, sustainable farming, and health advocacy organizations, including Beyond Pesticides, called on USDA to reverse its plan to eliminate its pesticide reporting program in 2008. Elimination of USDA’s objective data will open the door wide to serious misinformation on pesticide use, charge the groups. USDA claims it lacks funding to continue the program. “Americans are rightly concerned about the adverse impacts of pesticides on human health and the environment,” said Charles Benbrook, PhD, chief scientist at The Organic Center. “Without USDA’s data, our organizations will be severely hampered in our ability to carry out research on the impacts of pesticides and offer informed input on decision-making regarding pesticide use and pest management systems in American agriculture.” Dr. Benbrook, former executive director of the Board on Agriculture of the National Academy of Sciences, has used USDA’s pesticide data extensively in his work for many years. “We strongly oppose this move by USDA to cut the legs off its publicly available database. Denying the public and regulatory agencies this critical information is bad […]

(Beyond Pesticides, May 21, 2008) Top European Union (EU) official, Health Commissioner Androulla Vassiliou, called on European governments to adopt tougher guidelines on pesticides and to ban the use of all potentially dangerous pesticides that can cause cancer, reproductive effects and hormone disruption.The Health Commissioner urged agriculture ministers of member states not to ”˜water down’ recommendations in the two-year-old draft plan to introduce tougher guidelines on the use of pesticides. The plan, which needs approval by EU governments and the European Parliament, aims to tighten rules for authorizing new pesticides that come on to the EU market. It would also include mandatory recordkeeping by farmers, restrict the use of crop-dusters, force pesticide makers to reduce animal testing of their products, and stop the use of pesticides in sensitive areas near nature reserves and parks. “The key aim of the proposal is to protect the health of citizens and the environment, we must not lose sight of this,” Mr. Vassiliou told the ministers. Commissioner Vassiliou also stressed that pesticides that are toxic to reproductive systems, that disrupt hormones and those that cause cancer, should no longer be used to spray crops because of the risks to human and environmental health. Statistics […]

(Beyond Pesticides, May 20, 2008) On May 19, 2008, scientists, Arctic tribal governments and Indigenous groups and environmental health advocates sent letters calling on the Environmental Protection Agency (EPA) to phase out the organochlorine pesticide endosulfan.“It is time to take this dangerous and antiquated pesticide off the market,” says Jennifer Sass, Ph.D., a senior scientist with the Natural Resources Defense Council. “The scientific evidence clearly shows that the continued use of this chemical puts the health of exposed farmworkers, communities and the environment at risk.” Dr. Sass is one of over 55 international scientists, medical doctors, nurses, and other health professionals urging EPA to take action on endosulfan in a letter to Administrator Stephen Johnson. Prominent scientists endorsing the letter include Philip Landrigan, M.D., M.Sc., a pediatrician and Director of the Center for Children’s Health and the Environment at the Mount Sinai School of Medicine and Ronald Herberman, M.D. and Devra Davis, Ph.D., M.P.H., researchers at the University of Pittsburgh Cancer Institute. Used in the U.S. on tomatoes, cotton and other crops, endosulfan harms the hormone system, and low levels of exposure in the womb have been linked to male reproductive harm, other birth defects and possibly autism. Acute poisoning […]

(Beyond Pesticides, May 19, 2008) A 20-year study by the National Oceanic and Atmospheric Administration (NOAA) shows that environmental laws enacted in the 1970s are having a positive effect on reducing overall contaminant levels in coastal waters of the U.S. However, the report points to continuing concerns with elevated levels of metals and organic contaminants found near urban and industrial areas of the coasts. The report, “NOAA National Status and Trends Mussel Watch Program: An Assessment of Two Decades of Contaminant Monitoring in the Nation’s Coastal Zone from 1986-2005,” findings are the result of monitoring efforts that analyze 140 different chemicals in U.S. coastal and estuarine areas, including the Great Lakes.“It’s interesting to note that pesticides, such as DDT, and industrial chemicals, such as PCBs, show significant decreasing trends around the nation, but similar trends were not found for trace metals,” said Gunnar Lauenstein, manager of the NOAA Mussel Watch program. “What is of concern is that there are contaminants that continue to be problematic, including oil-related compounds from motor vehicles and shipping activities.” Significant findings from this report include the following: Decreasing trends nationally of the pesticide DDT are documented with a majority of the sites monitored along the […]

(Beyond Pesticides, May 16, 2008) Pressured by environmental organizations to protect children’s health and water quality in the Great Lakes, the Michigan House of Representatives has approved restrictions on the use of lindane, a toxic organochlorine pesticide used as a prescription drug to treat lice and scabies.  Under the legislation (HB 4569), the use of lindane  would be  prohibited except “under the supervision of a physician in his or her office if the physician considers the use of that product necessary for the treatment of a patient’s lice or scabies.” The Michigan Senate has not yet voted on the bill. Lindane has long been known for its neurotoxic properties, causing seizures, damage to the nervous system, and weakening of the immune system. It is also a probable carcinogen and endocrine disruptor. When used on people, lindane is regulated by the Food and Drug Administration (FDA). Despite the fact that it has been banned in 52 countries and restricted in over 30 more, FDA continues to allow its use in the U.S., albeit with a Public Health Advisory issued in 2003 that states, “Lindane should be used with caution in infants, children, the elderly, patients with skin conditions, and patients with […]

(Beyond Pesticides, May 15, 2008) The Environmental Protection Agency (EPA) has announced a plan to distribute pesticide labels electronically, in lieu of a traditional product labeling with use instructions, raising further safety concerns about consumer product choice and label compliance from public health and environmental advocates. The program, which is currently under development, will be an agenda item at the May 21-22 meeting of the Pesticide Program Dialogue Committee (PPDC) in Arlington, VA. “Benefits from using this system will include faster access to new pesticide uses, quicker implementation of protective measures for public health and the environment, improved compliance with label directions, and lower costs for industry and EPA,” the agency said May 12 in a statement on its pesticides website. The system will rely on users to contact either the pesticide labeling website or a toll-free telephone number to obtain the detailed-use instructions that previously were attached to pesticide containers, EPA said. The program is being discussed by EPA and “stakeholders, generally those that have approached the Agency.” EPA said it would develop a pilot program for the system in 2009. The PPDC, which will be presenting next week, comprises industrial, regulatory, and consumer members who provide feedback to […]

(Beyond Pesticides, May 14, 2008) On May 12, Judge Robert O’Farrell ruled on a lawsuit brought by Helping Our Peninsula’s Environment (HOPE), finding that California’s Agriculture Secretary, A.G. Kawamura, violated the law when the state aerially sprayed untested, ”˜secret’ pesticides on cities, children and wildlife. Judge O’Farrell then ordered the spraying stopped until the California Department of Food and Agriculture (CDFA) completes an Environmental Impact Report (EIR). HOPE attorney Alexander Henson said, “I’m glad that this case will set a precedent requiring government to do the required studies before they spray an unsuspecting populace with untested chemicals.” HOPE Trustee Terrence Zito said,  “Since last August HOPE has been saying that spraying people with secret, untested, unwanted pesticides is immoral and illegal. The courts have now twice confirmed that CDFA acted illegally.” Last month a Santa Cruz County Court ruled that the light brown apple moth (LBAM) was not an immediate threat and delayed aerial spraying of the pesticide, CheckMate (a pheromone-based pesticide with inert ingredients), in order for an EIR to be completed. In his ruling, presiding Judge Paul Burdick said the state did not prove that the invasive light brown apple moth poses an immediate threat to life or […]

(Beyond Pesticides, May 13, 2008) Citing concerns over the impact of pesticides on health and the environment, the Voorhees, NJ Township Committee approved Resolution 126-08, Township of Voorhees Pesticide Reduction Policy, on April 28, 2008 to stop hazardous pesticide use. The New Jersey Township has adopted Integrated Pest Management (IPM) as the pest control policy and strategy to be used in the maintenance of the township’s public properties and buildings, and township parks are pesticide free posted with “Pesticide Free Zone” ladybug signs.The National Center for Environmental Health Strategies, which proposed the resolution, will be working with the township’s pest control contractor on an IPM plan for township buildings to continue to eliminate or significantly reduce the use of hazardous pesticides. The guidance will in part be based on the New Jersey School IPM Law (S. 137, adopted September 26, 2002), which requires that after non-chemical means of pest control have been considered and exhausted and conventional pesticide use is deemed necessary, preference be given to using a pesticide that is classified “low impact.” Low impact pesticides according to the New Jersey School IPM Law include a first category of pesticides or substances that are U.S. EPA exempt from regulation […]

(Beyond Pesticides, May 12, 2008) Town officials in Camden, Maine passed a new policy that eliminates toxic pesticides from being applied to municipal parks and fields thanks to the grassroots efforts spearheaded by Citizens for a Green Camden. According to the Knox County Times Reporter, an advisory committee of citizens and town and school employees that are knowledgeable about organic pest management will oversee the policy’s implementation. The director of Camden’s Parks and Recreation Department, Jeff Kuller, stated that they will now look to mechanical methods and the use of vinegar to manage weeds on several of the town’s athletic fields.The policy states, “All pesticides are toxic to some degree and the widespread use of pesticides is both a major environmental problem and a public health issue. Federal regulation of pesticides is no guarantee of safety. Camden recognizes that the use of pesticides may have profound effects upon indigenous plants, surface water and ground water, as well as unintended effects upon people, birds and other animals in the vicinity of treated areas. Camden recognizes that all citizens, particularly children, have a right to protection from exposure to hazardous chemicals and pesticides.” The policy goes on to state, “Camden supports the […]

(Beyond Pesticides, May 9, 2008) The Center for Food Safety (CFS) yesterday sent letters to the Attorneys General of 49 states urging the top state law enforcement officials to take action against the misleading practice of labeling seafood imports as “organic.” The state-based effort to protect the integrity of organic food labels is a follow-up to the complaints filed by the Center last year with the USDA and Federal Trade Commission (see also Daily News of November 5, 2007). To date, these federal agencies have left the complaints unanswered, while U.S. consumers are increasingly confronted with imported seafood misleadingly labeled as “organic,” despite the fact that there are no U.S. organic seafood standards in place. In the action, the CFS calls upon USDA to prevent consumer deception by enforcing existing organic labeling laws and regulations until new standards are finalized. CFS, which is joined in this effort by Food & Water Watch, has identified the practice of allowing seafood to be labeled as “organic” in absence of regulations as unfair, deceptive and misleading – a violation of the states’ consumer deception and misrepresentation laws. With U.S. sales of organic food dramatically increasing, a number of foreign seafood imports labeled as […]

(Beyond Pesticides, May 8, 2008) New research shows that melting Antarctic glaciers are releasing once frozen stores of persistent organic chemicals, now banned in many parts of the world. Marine biologist, Heidi Geisz, a Ph.D. student at the Virginia Institute of Marine Science studying the fate and effect of organic contaminants in the Antarctic, has found that DDT concentrations in penguins has remained at the same levels as they were 30 years ago, when DDT was widely used. Arctic animals such as whales, seals and birds have had a significant decline in their DDT levels during the past decades, while the more stationary Antarctic penguins have not. The study, “Melting Glaciers: A Probable Source of DDT to the Antarctic Marine Ecosystem,” published in Environmental Science and Technology (DOI: 10.1021/es702919n), identifies the melting snow and ice as the continued source of total DDT in this southern ecosystem. The release of DDT also means that other persistent organic pollutants (POPs), including PCBs and PBDEs — industrial chemicals that have been linked to health problems in humans, are also being released. “DDT is not the only chemical that these birds are ingesting and it is certainly not the worst,” Ms. Geisz says. Ms. […]

(Beyond Pesticides, May 7, 2008) Twenty-five vineyards representing 925 acres or 56 percent of vineyard acreage in the Walla Walla Basin in Washington state, as well as the 110-acre Walla Walla Community College (WWCC), are newly certified “Salmon-Safe” for their land practices that help accelerate salmon’s recovery. The designation means that landowners go above and beyond regulations to adopt significant and specific measures that restore in-stream habitat, conserve water, protect streamside habitat and wetlands on site, reduce erosion and sedimentation, and reduce or eliminate the use of chemical pesticides.Certification is awarded only after comprehensive on-site assessments by independent inspectors based on Salmon-Safe’s rigorous standards. Salmon-Safe is a leading regional eco-label that in 11 years has certified more than 60,000 acres of farm and urban lands in Oregon and Washington, including one-third of Oregon’s vineyard acreage, as well as the headquarters campuses of Nike, Washington State Department of Ecology, and Kettle Foods.“The magnitude of the participation underscores the Walla Walla valley’s leadership in adopting and committing to sustainable practices that benefit people and land, and help salmon spawn and thrive,” said Dan Kent, Salmon-Safe managing director. “The certifications and assessments also mark a major expansion of Salmon-Safe east of the Cascades, […]

(Beyond Pesticides, May 6, 2008) Pregnant veterinarians who have occupational exposures to pesticides, anesthetic gases or radiation may have twice the risk of miscarriage, according to a new study published in the May 2008 issue of the journal Occupational and Environmental Medicine. The study, “Maternal occupational exposures and risk of spontaneous abortion in veterinary practice,” looked at the experiences of 1197 female veterinarians working in clinical practice, who graduated from Australian veterinary schools between 1960 and 2000, responding to a questionnaire-based survey. There was a twofold increase in the risk of miscarriage in women veterinarians who use pesticides at work. The researchers found that there was also a twofold increase for those exposed to anaesthetic gases for more than an hour a week without using equipment to remove the gas from the air, and an 80 percent greater risk of miscarriage in those who performed more than five x-ray examinations per week compared with those who performed five or less. Veterinarians are often unable to leave the room whilst performing an x-ray because they have to hold the animal being x-rayed in order to restrain it. Adeleh Shirangi, Ph.D., author of the research from the Department of Epidemiology and Public […]

(Beyond Pesticides, May 5, 2008) A new study indicates that some pesticides applied to golf courses in the Precambrian Shield of central Ontario may have an impact on aquatic organisms in adjacent watersheds. The study is published in the April issue of Environmental Toxicology and Chemistry. Golf courses affect the environment by altering the habitat through the release of nutrients and pesticides. The Precambrian Shield region of central Ontario, Canada, a major recreational area, is especially susceptible to the impacts of golf courses as a result of the geology and hydrology of the region. The Shield area is characterized by many lakes, rivers, and streams. Golf courses in this area typically place turf on top of a sand base which allows chemicals used on the courses to migrate into surrounding bodies of water. The study set out to determine (1) whether organic substances that are toxic to early life stages of fish are transported from golf courses in the Precambrian Shield and (2) whether toxic compounds occur in watersheds of golf courses at times that coincide with the application of pesticides to golf courses and other conditions conducive to surface runoff. To do so, two golf courses in the Muskoka […]

(Beyond Pesticides, May 2, 2008) The International Center for Technology Assessment (CTA) and a coalition of consumer, health, and environmental groups, including Beyond Pesticides, yesterday filed a legal petition with the Environmental Protection Agency (EPA), demanding the agency use its pesticide regulation authority to stop the sale of  250+ consumer products now using nanosized versions of silver. The legal action is the first challenge to EPA’s failure to regulate nanomaterials. Increasingly, manufacturers are infusing a large and diverse number of consumer products with nanoparticle silver (“nanosilver”) for its enhanced “germ killing” abilities. Nanosilver is now the most common commercialized nanomaterial. CTA found over 260 nanosilver products currently on the market, ranging from household appliances and cleaners to clothing, cutlery, and children’s toys to personal care products and coated electronics. Yet as the legal petition addresses, the release of this unique substance may be highly destructive to natural environments and raises serious human health concerns. Last summer, a coalition of 40 organization called for much more comprehensive evaluation and regulation of nanomaterials, citing these concerns. “These nanosilver products now being illegally sold are pesticides,” said George Kimbrell, CTA nanotech staff attorney. “Nanosilver is leaching into the environment, where it will have […]

(Beyond Pesticides, May 1, 2008) In testimony responsive to a request last year by Senators Barbara Boxer (D-CA) and Hillary Clinton (D-NY), the Government Accountability Office (GAO) told the Senate Committee on Environment and Public Works on April 29 that EPA’s risk review process is plagued by delays, a lack of transparency, and interference from the White House and other agencies. In short, GAO concluded that the agency’s science is politicized, outdated, secret, and threatens the protection of people and the environment from harmful chemical exposures. In its testimony, GAO’s director of Natural Resources and Environment, John Stephenson, urged Congress to suspend EPA plans for reform, which GAO believes would institutionalize bad science, and require the agency to adopt its recommendations. The testimony comes on the heels of an April 10, 2008 EPA decision, effective immediately, to revise its Integrated Risk Information System (IRIS). The program was severely criticized by GAO in a March 2008 report, Chemical Assessments: Low Productivity and New Interagency Review Process Limit the Usefulness and Credibility of EPA’s Integrated Risk Information System (GAO-08-440). While EPA said it would consider the report’s recommendations, GAO said in its testimony this week, Toxic Chemicals: EPA’s New Assessment Process Will […]

(Beyond Pesticides, April 30, 2008) New research shows that socks impregnated with silver nanoparticles to keep them microbe and odor free, release these particles when washed. Once washed down the drain, the silver particles enter the environment where they may pose numerable unknown adverse effects. Researchers from Arizona State University report their findings in a study entitled; “Fate and transport of ionic and nanoparticle silver released from commercially available socks,” published in Environmental Science and Technology. Six commercial brands of nanosilver-treated socks were tested and their nanosilver content measured before and after wash. The socks were soaked in 1- or 24-hour-long wash cycles in distilled water without detergent to limit variables in the tests. One batch was soaked in tap water to simulate a more realistic washing.Using scanning and transmission electron microscopy, the remaining silver was analysed. Under the microscope, nanoparticles were found clumped together in the fabric, while some socks had tiny corkscrew-shaped nanosilver particles that stuck like burrs to the fabric, clinging more tightly than some simpler nanosilver forms. They found that socks had variable leaching rates, which suggests that the sock manufacturing process and how they are impregnated with silver may influence the release of silver. In […]

(Beyond Pesticides, April 29, 2008) In the wake of provincial laws banning lawn chemicals, the Canadian division of Home Depot announced on April 22, 2008 that it will stop selling traditional pesticides in its stores across Canada by the end of 2008 and will increase its selection of environmentally friendly alternatives. Home Depot Canada is the first major home improvement retailer to stop selling pesticides nationwide.The decision coincides with legislation introduced on April 23, which bans the sale and cosmetic use of pesticides on lawns, gardens and parks in the Canadian province of Ontario. Quebec passed a similar ban in 2003. Additionally, there are currently over 55 municipalities in Canada where the residential use, but not sale, of pesticides is banned. Other garden supply and grocery stores have also stopped selling pesticides in Ontario and Quebec, but the Home Depot decision will affect stores nationwide. Environmental and public health activists believe the provincial bans and Home Depot phase-outs demonstrate that the country has reached a tipping point. “I would say that now that we have Quebec and Ontario, there is huge pressure on the other provinces. The next obvious one would be British Columbia.” Gideon Forman, executive director of the […]
