(Beyond Pesticides, April 28, 2009) On April 23, 2009, the Natural Resources Defense Council (NRDC) filed a lawsuit, NRDC v. Albertsons, Inc. et al, in California against major pet product retailers and manufacturers for illegally selling pet products containing a known cancer-causing chemical called propoxur without proper warning labels. In new scientific analysis also released the same day, NRDC found high levels of propoxur and tetrachlorvinphos (TCVP), another carcinogenic neurotoxin common in household pet products, on pet fur after use of ordinary flea collars. NRDC is also petitioning the Environmental Protection Agency (EPA), calling for the removal of these chemicals from pet products. “Just because a product is sold in stores does not mean it is safe,” said Gina Solomon, MD, NRDC senior scientist and physician. “Under California law, consumers have a right to know if a flea control product exposes them to health risks before they buy it.” NRDC filed its lawsuit in California Superior Court in Alameda County against 16 retailers and manufacturers including Petsmart, PetCo, and Petstore.com, for failing to comply with California’s Safe Drinking Water and Toxic Enforcement Act, known as Proposition 65, which prohibits businesses from knowingly exposing consumers without proper warning to any chemical […]

(Beyond Pesticides, April 24, 2009) The California Department of Pesticide Regulation this week finalized looser pesticide rules that will allow more emissions from soil fumigant pesticides. Environmental activists are alarmed that this new ruling will only serve to slow efforts to clean the smoggy air in California’s Central Valley. This regulatory action revises the total pesticide emission benchmarks in the Sacramento Metro, San Joaquin Valley, South Coast, Southeast Desert, and Ventura areas. The ruling is a victory for chemical-intensive farmers, who fear that stricter limits would force some growers to stop using pesticides. Pesticides, especially soil fumigants, which are injected into soil to kill pests by releasing toxic gases, contribute to about 6% of the smog problem in the Valley, according to state figures. According to the state’s Department of Pesticides Regulation, the looser limit will still “meet our obligation to reduce pesticide emissions, but do so in a way that avoids placing an unreasonable or disproportionate burden on fumigant pesticide users.” For the San Joaquin Valley for example, the rule sets the emissions limit at 18.1 tons per day, 2.1 tons higher than what activists wanted. The regulations cover the prime growing season of May 1 though October 31 […]

(Beyond Pesticides, April 22, 2009) The California Department of Pesticide Regulation (DPR) released its “Top Pesticide Blunders” report to remind the public to avoid illness and injury by using household cleaning and gardening products that pose the least risk to their health and the environment. The blunders also include situations in which users of toxic products fail to comply with product labels. “Disinfectants, mold and mildew cleaners, weed killers and pool chemicals are just a few of the many over-the-counter pesticide products available for home use,” DPR Director Mary-Ann Warmerdam said. “As people begin their spring cleaning and gardening, they should select products that best target the problem and then follow the label instructions carefully to prevent accidents.” Beyond Pesticides adds that people should consider non-chemical approaches that manage unwanted insects and plants with prevention-oriented practices. Ms. Warmerdam suggests the following precautions to prevent pesticide exposure in and around the home: *Select products that pose the least risk to your health and the environment — do you really need a pesticide for the task? *Never put pesticides in food or drink containers. Keep pesticides in their original containers so they are not mistaken for food or drink. *Store pesticides properly […]

(Beyond Pesticides, April 17, 2009) Thirteen years after the Food Quality Protection Act (FQPA) ordered EPA to develop a screening process for endocrine disrupting chemicals, the Environmental Protection Agency (EPA) has released a final list of chemicals to be included in Tier 1 testing for endocrine disrupting effects of pesticides in use. While the list has been reduced from the 73 chemicals announced two years ago, trials will begin this summer to determine human risk from some of the chemicals to which we are most commonly exposed. “Endocrine disruptors can cause lifelong health problems, especially for children,” stated EPA Administrator Lisa Jackson. “Gathering this information will help us work with communities and industry to protect Americans from harmful exposure.” EPA’s recent announcement of these chemicals can be found on EPA’s Endocrine Disruptor Screening Program (EDSP) page. According to EPA, “The Agency deleted 6 chemicals from the draft list of 73 based upon recent information showing that the chemicals are no longer expected to be found in 3 exposure pathways.” To be included on the initial list, EPA established that chemicals need to be found in three of EPA’s four exposure pathways: food, drinking water, residential use, and occupational exposure. Azinphos-methyl […]

(Beyond Pesticides, April 16, 2009) The U.S. Environmental Protection Agency (EPA) convened the first ever National Bed Bug Summit (April 14-15, 2009) to solicit recommendations from scientists, state and local officials, pest control operators and the general public on how to tackle the resurgence of the blood sucking insects. Bed bugs have rebounded in significant numbers for the first time since World War II, partly due to increased global travel and their increasing resistance to commonly used pesticides. Bed bug outbreaks have tripled since 2005, according to a survey of 800 pest control firms across the country, infesting apartment buildings, college dormitories, hospital wings, homeless shelters and top-rated hotels. Bedbugs outbreaks have been reported in at least 27 states, including Honolulu, San Francisco, Cincinnati, Chicago, Houston and Miami. In 2006, a Chicago woman sued a New York hotel for $20 million after suffering more than 500 bed bug bites. Persistent outbreaks are normally concentrated in low-income neighborhoods, where people cannot afford to replace or professionally clean bedding and soft furnishing. Both New York and San Francisco have passed city legislation to help control the spread of the bugs. In San Francisco, the legislation centers on landlord and tenant rights while […]

(Beyond Pesticides, April 15, 2009) Stating that it represents a danger to the environment, Germany’s Federal Minister for Nourishment, Agriculture and Consumer Protection, Ilse Aigner, announced an immediate ban on Monsanto’s MON810 genetically engineered (GE) maize yesterday. Claiming the decision is based on science and is an individual case, not a broad banning of all GE crops, Ms. Aigner stated, “Genetic engineering must include a complete guarantee of the security for person, animal, plant and environment.” Environmentalists, scientists and farmers opposed to GE crops have argued that the corn, which confers resistance to pests, could pollute other crops and pose a threat to the environment and human health. The debate over the use of GE crops in Europe has been ongoing for at least a decade. MON810 maize, brand name YieldGard, is the only GE crop currently cultivated in the European Union (EU). Under EU laws, countries are allowed to ban individual GE crops for environmental and health reasons. Currently, Hungary, France, Austria, Greece and Luxembourg ban MON810 maize. In March, EU environment ministers overwhelmingly rejected a European Commission proposal to force Austria and Hungary to lift their bans on the controversial cultivation of varieties of genetically modified (GM) corn.

G(Beyond Pesticides, April 14, 2009) Groups are seeking an end to a failed U.S.-supported herbicide spray program that between 2000 and 2008 cost U.S. taxpayers more than half a billion dollars to apply the toxic herbicide glyphosate on approximately three million acres of land in Colombia””the world’s second most biodiverse country. The herbicide spraying, targeted at coca — the raw ingredient used to make cocaine, is toxic to people and wildlife, wreaks havoc on native ecosystems and has proven to be an ineffective tactic in the “War on Drugs.” Beyond Pesticides encourages you to join with EarthJustice and send a letter to the Obama Administration asking the government to stop supporting this destructive policy. Colombia is the only country in the world that allows this kind of herbicide spraying””known as fumigation””as an anti-drug practice. Yet the spraying has been a complete failure. According to U.S. government studies, the area subject to coca cultivation has actually increased by 23 percent since the U.S.-backed fumigation began in earnest, and Colombia remains the leading supplier of cocaine for U.S. markets. Coca farmers simply spread out and relocate the crops, moving deeper into the forest and clearing new areas. The environmental impacts have been […]

(Beyond Pesticides, April 10, 2009) In the U.S., lindane is a pesticide approved for use in children’s lice shampoo, but not on pets or plants. In much of the rest of the world, including Mexico, all uses of lindane have been banned for years. Parents, health professionals, and Arctic communities — whose food and breast milk are contaminated with a chemical they do not use — are urging US officials to close this loophole. Government delegates will gather in Geneva early next month to decide whether lindane will be added to a list of chemicals targeted for a global phase out under the international Stockholm Convention. In a letter to Secretary of State Hillary Clinton and Acting Commissioner of the Food and Drug Administration Joshua Sharfstein, a coalition of groups are calling on the agency leaders to support listing of lindane under the international treaty without exemption for lotions and shampoos (“pharmaceutical uses”). The letter also urges FDA to “take definitive action in ending pharmaceutical use of lindane domestically, as has already been accomplished in California.” “These lindane shampoos and lotions have already been banned in California and in many countries around the world,” says Kristin Schafer, Associate Director for […]

(Beyond Pesticides, April 8, 2009) The Northwest Coalition for Alternatives to Pesticides (NCAP) and Beyond Pesticides are asking that you take action to help secure everyone’s right to know about “secret” hazardous ingredients found in commonly used farm and household pesticide products. Please e-mail Environmental Protection Agency (EPA) administrator Lisa Jackson at [email protected], no later than May 1, urging EPA to respond to NCAP’s petition and mandate that pesticide manufacturers list hazardous “inert” ingredients on pesticide labels. “Inert” refers to ingredients in a pesticide formulation that have been added to the active ingredient to serve a variety of functions, such as acting as solvents, surfactants, or preservatives. However, the common misconception is that “inert” ingredients are physically, chemically, or biologically inactive substances. EPA allows pesticide manufacturers to put harmful chemicals into pesticide products without telling the public — chemicals linked with cancer, genetic damage, and reduced fertility, despite admitting the policy is misleading. EPA has stated that “many consumers have a misleading impression of the term ”˜inert ingredient,’ believing it to mean water or other harmless ingredients.” A December 2006 commentary in the National Institute of Environmental Health Sciences’ journal Environmental Health Perspectives calls for improvements in pesticide regulation and […]

(Beyond Pesticides, April 2, 2009) Last summer, when a pesticide tank exploded at a Bayer chemical plant in West Virginia, comparisons between the site’s potential risk and the 1984 Bhopal disaster, in which an explosion and leak at the Bayer site’s sister plant killed thousands, were drawn. The investigation into the West Virginia incident is ongoing, but recent reports show that Bayer is using every means to prevent full disclosure of the potential for a similar disaster to occur in the United States. Like Union Carbide’s Bhopal plant, Bayer stores stockpiles of the highly toxic chemical methyl isocyanate (MIC) in Institute, West Virginia. The U.S. plant has the capacity to store more than twice the amount of MIC that was leaked in Bhopal. The Chemical Safety and Hazard Investigation Board, a nonregulatory agency, is conducting an investigation into the cause of last year’s explosion, emergency response coordination, and future prevention measures. However, Bayer has invoked the 2002 federal Maritime Transportation Security Act because its campus is attached to a dock on the Kanawha River, claiming the Act exempts it from sharing “sensitive security information” due to potential terrorism. The board has already canceled one public meeting on the investigation, the […]

(Beyond Pesticides, April 1, 2009) A study published in the April 2009 issue of the medical journal Acta Paediatrica reports that the highest rates of birth defects for U.S. babies arise when conception occurs during the spring and summer months, when pesticide use increases and high concentrations of pesticides are found in surface waters. The study entitled, “Agrichemicals in surface water and birth defects in the United States” is the first study to link increased seasonal concentration of pesticides in surface water with the peak in birth defects in infants conceived in the same months. Researchers analyzed all 30.1 million births in the U.S. between 1996 and 2002. A strong association between higher rates of birth defects among women whose last menstrual period was in April, May, June or July and elevated levels of nitrates, atrazine and other pesticides in surface water during those same months was found. The correlation between the month of last menstrual period and higher rates of birth defects is statistically significant for half of the 22 categories of birth defects reported in the Centers for Disease Control database from 1996 to 2002, including spina bifida, cleft lip, clubfoot and Down’s syndrome. “Elevated concentrations of pesticides […]

(Beyond Pesticides, March 25, 2009) Canadian researchers have discovered a new class of fungicides that can bolster a plant’s natural defenses against fungal attack. Unlike conventional fungicides, researchers say these new anti fungal agents, called paldoxins and based on natural plant chemicals, may prove to be safer, more selective and less likely to fall victim to pests becoming resistant. In a report presented at the 237th National Meeting of the American Chemical Society on March 23 in Salt Lake City, Utah, researchers at the University of Saskatchewan, Canada, describe their development of six synthetic versions of the new anti-fungal agent, which works to block fungal enzymes that overwhelm plants’ natural defenses. Plant chemicals, called phytoalexins, are responsible for the defense mechanism exhibited by many plants to kill disease-causing fungi. However, many fungi release enzymes that detoxify, or destroy the phytoalexin, leaving the plant vulnerable to the fungi’s attack. The researchers took advantage of this counterattack strategy by developing anti-fungal agents to block the fungi’s destruction of phytoalexins. Paldoxins are short for phytoalexin detoxification inhibitors. Lead researcher, Soledade Pedras, PhD, and her colleagues discovered these agents after screening broccoli, cauliflower, mustard greens and other plants in the so-called “crucifer family” of […]

(Beyond Pesticides, March 19, 2009) Researchers investigating the long-term immune effects of dioxin have found that exposure to dioxin during development or while nursing diminishes the capacity to fight infection later in life. The study, published in Toxicological Sciences, reported that mouse pups born to pregnant mice that were exposed to a small amount of dioxins had fewer white blood cells that normally kill the flu virus and more of a different kind that increases lung inflammation. The study entitled, “The aryl hydrocarbon receptor affects distinct tissue compartments during ontogeny of the immune system,” aimed to identify the critical windows of exposure where fetuses are most sensitive to dioxin’s harmful effects. Pregnant mice were given a dose of 1,000 ppt dioxin either during pregnancy, lactation, or throughout pregnancy and lactation. After dosing, mothers and pups were kept dioxin-free. Researchers then infected mothers and pups with a non-lethal dose of the influenza virus. Researchers found that the number of specialized white blood cells – referred to as CD8+ T-cells that specifically recognize and kill the flu virus, were significantly reduced in the pups but not their mothers. The most severe reduction in these white blood cells was seen when dioxin was […]

(Beyond Pesticides, March 16, 2009) Exposure to a mixture of the fungicide maneb and the herbicide paraquat significantly increases the risk of developing Parkinson’s disease, according to a new University of California, Berkeley study, “Parkinson’s Disease and Residential Exposure to Maneb and Paraquat from Agricultural Applications in the Central Valley of California.” Published in the American Journal of Epidemiology, the study findings show that exposure to both pesticides within 500 meters of an individual’s home increases the risk of developing Parkinson’s by 75 percent. For individuals 60 years of age or younger at the time of diagnosis, there is a more than four-fold increase in risk of the disease when exposed to a combination of maneb and paraquat and a more than doubling of risk when exposed to either maneb or paraquat alone. The Berkeley researchers used geographic information systems that analyzed data from California Pesticide Use Reports and land-use maps to calculate historical residential exposure to agricultural exposure to the two pesticides. From 1998 to 2007, the researchers enrolled 368 incident Parkinson’s disease cases and 341 population controls from California’s Central Valley and developed potential exposure estimates incurred between 1974 and 1999. Also published this month by some of […]

(Beyond Pesticides, March 13, 2009) National Women’s History Month (March 2009) features a new film honoring Rachel Carson, the woman who launched the modern environmental movement. The film, A Sense of Wonder, will be screened nationwide to celebrate today’s women leaders who are saving the planet. Beyond Pesticides believes that the film, which is available on DVD, is a great tool for community organizers. March activities include three major city celebrations and film premieres: Washington, DC: Wednesday, March 18, 7:00pm at the National Portrait Gallery. Co-sponsored by the Environmental Film Festival. (8th & F Streets NW, Washington, D.C., 20001) Los Angeles: Thursday, March 19, 7:30pm at the Laemmle Music Hall Theater.

Al […]

(Beyond Pesticides, March 5, 2009) A new study published in the March 2009 issue of Environmental Health Perspectives finds that pesticide combinations cause more harm to endangered salmon than ndividual pesticide exposure. This means that single-pesticide risk assessments required by the Environmental Protection Agency (EPA) inadequately assess hazards. Mixtures of organophosphate and carbamate pesticides are commonly detected in freshwater habitats that support threatened and endangered species of Pacific salmon. According to the researchers from the National Oceanic and Atmospheric Administration (NOAA) Fisheries and Washington State University, these pesticides inhibit the activity of acetylcholinesterase (AChE) and thus have potential to interfere with behaviors that may be essential for salmon survival. The researchers measured brain AChE inhibition in juvenile coho salmon exposed to sublethal concentrations of the organophosphates diazinon, malathion, and chlorpyrifos, as well as the carbamates carbaryl and carbofuran. The pesticides were tested individually and in combination. They plotted AChE levels on a curve to determine whether the toxicologic responses to binary mixtures were additive, antagonistic (lesser than additive) effect, or synergistic (greater than additive). The authors observed addition and synergism, with a greater degree of synergism at higher exposure concentrations. Several combinations of organophosphates were lethal at concentrations that were […]

(Beyond Pesticides, March 4, 2009) The Ontario government is set to announce sweeping new regulations that will prohibit the use of 85 chemical substances, found in roughly 250 lawn and garden products, from use on neighborhood lawns. Once approved, products containing these chemicals would be barred from sale and use for cosmetic purposes. On November 7, 2008, the Ontario government released a proposed new regulation containing the specifics of the Cosmetic Pesticides Ban Act, passed last June. Then, Ontario joined Quebec in restricting the sale and cosmetic use of pesticides but environmental and public health advocates said then that the new law preempted local by-laws and actually weakens protections in some municipalities with stronger local protections. There are over 55 municipalities in Canada where the residential use, but not sale, of pesticides is banned. The prohibition of these 85 substances is the latest step in this Act. The proposal contains: ”¢ List of pesticides (ingredients in pesticide products) to be banned for cosmetic use ”¢ List of pesticide products to be banned for sale ”¢ List of domestic pesticide products to be restricted for sale. Restricted sale products include those with cosmetic and non-cosmetic uses (i.e., a product that’s allowed […]

(Beyond Pesticides, March 3, 2009) National radio commentator, writer and author Jim Hightower will be speaking at the 27th National Pesticide Forum, Bridge to an Organic Future: Opportunities for health and the environment, April 3-4, 2009 in Carrboro, NC. Twice elected Texas Agriculture Commissioner, Mr. Hightower believes that the true political spectrum is not right to left but top to bottom, and he has become a leading national voice for the 80 percent of the public who no longer find themselves within shouting distance of the Washington and Wall Street powers at the top. His talk at the Forum is called, “Putting ‘Progress’ Back In Progressive: The route to social justice, fair food and a sustainable environment.” In his latest book, Swim Against The Current: Even A Dead Fish Can Go With The Flow, America’s most irascible and hilarious curmudgeon turns a kind and benevolent eye toward brave, hardy, and hardworking souls around the country who have found ways to break free from corporate tentacles; redefine success in business, politics, and life in general; and blaze new pathways toward a richer and happier way of life, from the farmers’ cooperative that said “NO!” to Wal-Mart and thrived to the economists […]

(Beyond Pesticides, March 2, 2009) Pesticide exposure and genetic variability in the dopamine transporter (DAT), a protein that plays a central role in dopaminergic neurotransmission of the brain, interact to significantly increase the risk factor for Parkinson’s disease, according to a new study by University of California, Los Angeles (UCLA) researchers. The population based case-control study, “Dopamine Transporter Genetic Variants and Pesticides in Parkinson’s Disease,” builds on the existing body of evidence of animal data and epidemiological studies that link exposure to pesticides, including gene-pesticide interactions, to Parkinson’s disease. The UCLA researchers, looking at incident Parkinson’s disease cases in three rural counties in Central California, find DAT increases the risk of Parkinson’s when individuals have occupational or residential exposure to pesticides. This is the first epidemiologic study of Parkinson’s disease that relies on pesticide data that is from a record-based source versus recall-based data relying on individuals’ memory. The second most common neurodegenerative disease affecting more than one million people in the U.S., Parkinson’s disease occurs when nerve cells in the substantia nigra region of the brain are damaged or destroyed and can no longer produce dopamine, a nerve-signaling molecule that helps control muscle movement. The new UCLA study is […]

(Beyond Pesticides, February 25, 2009) After three years of legal battle, the North Carolina Pesticide Board on February 19, 2009 fined Florida-based Ag-Mart Produce Inc. a substantially lower fine of $3,000 than the originally proposed $185,000, after deciding that it can only prove six of about 200 worker safety accusations that had been levied against the company. This comes less than a month after the unprecedented ruling against Ag-Mart in New Jersey, where the company was ordered to pay penalties of more than $931,000 for misusing pesticides and jeopardizing the health and safety of workers in its New Jersey farm fields and packing houses. The Florida-based company, described as one of the biggest pesticide offenders, has been accused of routinely exposing hundreds of workers to toxic chemicals. Investigators in North Carolina, Florida and New Jersey, the three states where the international company grows its tomatoes, scrutinized the company’s records and charged it with ignoring laws intended to keep workers safe from toxic pesticide residue. The investigators alleged workers were sent into the fields too soon after dangerous chemicals had been sprayed. The case started three years ago when some workers gave birth to babies with severe birth defects. One mother […]

(Beyond Pesticides, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, February 23, 2009) Permethrin and lindane metabolites are found in children who use lice shampoos containing the insecticides, according to researchers affiliated with the Centers for Disease Control and Prevention. The study, “Pesticide exposure resulting from treatment of lice infestations in school-aged children in Georgia,” published in the February issue of the journal Environment International, is the first to measure children’s exposure to chemical lice treatments. The researchers collected baseline urine samples from 78 enrolled children between the ages of six to ten years of age. About one-third of those children were diagnosed with head lice and subsequently treated with at least one over-the-counter permethrin lice treatment, a prescription lindane treatment, or both. Within seven days of the insecticide application, urine samples were again collected. The permethrin exposed children had significantly higher urinary pryrethoid metabolite levels in their post-exposure urine samples. Lindane metabolites were also elevated in urine samples after treatment. Interestingly, the study states, “Exposed participants appeared to have higher pre-exposure metabolite levels — likely from multiple treatments before enrollment — than unexposed participants.” Pentachlorophenol, a metabolite of lindane, was significantly higher in the urine of those children who used a lice treatment regardless of whether it […]
