(Beyond Pesticides, July 10, 2009) The Center for Biological Diversity notified the U.S. Environmental Protection Agency (EPA) earlier this week of its intent to file suit against the agency for failing to consider impacts to the polar bear and its Arctic habitat from toxic contamination resulting from pesticide use in the U.S. Pesticides registered by EPA for use in the U.S. are known to be transported to the Arctic via various atmospheric, oceanic, and biotic pathways. Such pesticides are biomagnified with each step higher in the food web, reaching some of their greatest concentrations in polar bears, the apex predators of the Arctic. A body of literature demonstrates the far-reaching effects of commonly used pesticides that are suspected endocrine disruptors and persistent organic pollutants, such as atrazine, 2,4-D, lindane, endosulfan, and permethrin, on global ecosystems. These pesticides, among others, and related contaminants have been linked to suppressed immune function, endocrine disruption, abnormalities in reproductive organs, hermaphroditism, and increased cub mortality in polar bears. Human subsistence hunters in the Arctic, who share the top spot on the food web with the polar bear, also face increased risks from exposure to these contaminants. “The poisoning of the Arctic is a silent crisis […]

(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, July 2, 2009) The EPA has just finished up with a round of public hearings on a proposed plan to cap a part of the Palos Verdes Superfund Site. This 17 square mile area of ocean floor off the Southern coast of California is home to one of the largest deposits of DDT in the U.S. Despite the fact that this chemical has been banned in the U.S. for almost four decades, there is an approximate 110 tons of DDT in the sediment of the Palos Verdes Shelf. Concentrations of DDT and PCBs in fish continue to pose a threat to human health and the natural environment including the discovery of highly contaminated fish. In addition, a surge of additional problems with the lingering effects of DDT have risen in recent years, particularly with its buildup in our waterways. It has currently been identified as a threat to the Columbia River, as well as to the arctic. It has also been linked to a plethora of health concerns, including breast cancer, diabetes, non Hodgkin lymphoma, and autism. Most of the contamination of the Palos Verdes Shelf is attributed to The Montrose Chemical Corporation of California. At one time […]

(Beyond Pesticides, July 1, 2009) Researchers have found that one of the so-called “inert” ingredients in the popular herbicide product Roundup can kill human cells, particularly embryonic, placental and umbilical cord cells. Over 4,000 inert ingredients are approved for use in the U.S. and can be mixed with pesticide “active” ingredients; however these chemicals are not disclosed to consumers or users on pesticide product labels due to EPA’s intepretation (many would say incorrect interpretation) of federal pesticide law. Many inerts are classified as highly toxic, while others have not been adequately studied. About 100 million pounds of Roundup are applied to U.S. farms and lawns every year and until now, most health studies have focused on the safety of glyphosate the active ingredient in Roundup, rather than the mixture of “inert” ingredients found in the herbicidal product. In this new study, “Glyphosate Formulations Induce Apoptosis and Necrosis in Human Umbilical, Embryonic, and Placental Cells,” researchers found that Roundup’s inert ingredients amplified the toxic effect on human cells””even at concentrations much more diluted than those used on farms and lawns, and which correspond to low levels of residues in food or feed. One specific inert ingredient, polyethoxylated tallowamine, or POEA, was […]

(Beyond Pesticides, June 29, 2009) Last week the United States Court of Appeals for the Ninth Circuit re-affirmed its previous decision upholding a nationwide ban on the planting of genetically-engineered (GE) Roundup Ready alfalfa pending a full Environmental Impact Statement (EIS). The Court determined that the planting of genetically modified alfalfa can result in potentially irreversible harm to organic and conventional varieties of crops, damage to the environment, and economic harm to farmers. Although the suit was brought against the United States Department of Agriculture (USDA), Monsanto Company and Forage Genetics entered into the suit as Defendant-Intervenors. In September 2008 the Ninth Circuit affirmed the lower court’s ruling, but the Intervenors continued to press the appeal alone, requesting the appellate court to rehear the case. Last weeks decision denied that request and re-affirmed the earlier decision in full. “This ruling affirms a major victory for consumers, ranchers, organic farmers, and most conventional farmers across the country,” said Andrew Kimbrell, Executive Director of the Center for Food Safety. “Roundup Ready Alfalfa represents a very real threat to farmers’ livelihoods and the environment; the court rightly dismissed Monsanto’s claims that their bottom line should come before the rights of the public and […]

(Beyond Pesticides, June 25, 2009) Although it is known that infants are more susceptible than adults to the toxic effects of pesticides, this increased vulnerability may extend much longer into childhood than expected, according to a new study by researchers at the University of California, Berkeley. Among newborns, levels of paraoxonase 1 (PON1), an enzyme critical to the detoxification of organophosphate pesticides, average one-third or less than those of the babies’ mothers. It was thought that PON1 enzyme activity in children approached adult levels by age two, but instead, the UC Berkeley researchers found that the enzyme level remained low in some individuals through age seven. Based upon the findings, reported in the journal Environmental Health Perspectives, the study authors recommend that the U.S. Environmental Protection Agency (EPA) re-evaluate the current standards for acceptable levels of pesticide exposure. “Current EPA standards of exposure for some pesticides assume children are three to five times more susceptible than adults, and for other pesticides the standards assume no difference,” said Nina Holland, Ph.D., UC Berkeley adjunct professor of environmental health sciences and senior author of the paper. “Our study is the first to show quantitatively that young children may be more susceptible to […]

(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 […]

(Beyond Pesticides, June 22, 2009) In April 2009, the U.S. Environmental Protection Agency (EPA) announced that it is intensifying its evaluation of spot-on pesticide products for flea and tick control for pets due to recent increases in the number of reported incidents. Adverse reactions reported range from mild effects such as skin irritation to more serious effects such as seizures and, in some cases, the death of pets. Incidents with flea and tick products can involve the use of spot-on treatments, sprays, collars and shampoos. However, the majority of the incidents reported to EPA are related to flea and tick treatments with EPA-registered spot-on products. Spot-on products are generally sold in tubes or vials and are applied to one or more localized areas on the body of the pet, such as in between the shoulders or in a stripe along the back. This advisory pertains only to EPA-registered spot-on flea and tick products; these products have an EPA registration number on the label. EPA now is evaluating all available data on the pesticides, including reports of adverse reactions, clarity of product use directions and label warnings, product ingredients, market share, and pre-market safety data submitted to the Agency. EPA says […]

(Beyond Pesticides, June 19, 2009) Farmworker unions, support groups, and worker advocacy organizations today asked Environmental Protection Agency (EPA) Administrator Lisa P. Jackson to stop the pesticide poisoning of farmworker communities and uphold the Obama administration’s commitment to environmental justice. Citing a long EPA history of “inhumane neglect of toxic pesticide effects on farmworker community health,” the groups asked the Administrator to amend a recent May 2009 decision that allows the continued use of hazardous soil fumigant pesticides. The chemicals when used in chemically treated crop production, such as tomatoes, carrots, strawberries and nuts, escape into the environment and drift into communities where the families and children of farmworkers live and play. The letter, signed by 28 groups from across the country, says that the new fumigants policy “continues an outdated EPA approach to pesticide regulation that adopts unrealistic and unenforceable standards as risk mitigation measures, in an age of safer, greener approaches to agricultural pest management.” EPA announced its decision May 27, 2009 to allow continued use of toxic soil fumigants with modified safety measures, falling far short of safety advocate efforts to adopt more stringent use restrictions and chemical bans. The rule was first proposed in July 2008, […]

(Beyond Pesticides, June 18, 2009) Do you ever wonder about pesticides on your food or in your drinking water, and in particular, which of those pesticides are most hazardous? On June 17, 2009, Pesticide Action Network North America (PANNA) launched its What’s On My Food database, which makes the results of government tests for pesticide residues in food available online in a searchable, easy-to-use format. The database shows what pesticides are found on each food, in what amount, and — for the first time — links those residues to the health effects associated with exposure to each of the chemicals. “This kind of public visibility around pesticides is particularly needed in the U.S., since regulators base their decisions on toxicology studies that are almost all done by industry,” explains Brian Hill, PhD, senior PANNA scientist and the primary developer of the database. “Nearly 900 million pounds of pesticides [excluding wood preservatives, chlorine and specialty biocide pesticides] are used in the U.S. every year, yet regulations depend on studies that are not peer-reviewed and are kept hidden behind the veil of ”˜confidential business information.’” Dr. Hill notes that the 900 million figure is long overdue for updating, as the most recent […]

(Beyond Pesticides, June 17, 2009) A new study finds that toxic pesticides, including those already banned, persist in homes. The study’s results indicate that most floors in occupied homes in the U.S. have measurable levels of insecticides that serve as sources of exposure to home dwellers. These persistent residues continue to expose people, especially vulnerable children, to the health risks associated with these chemicals. Published in Environmental Science and Technology, the study, entitled “American Healthy Homes Survey: A National Study of Residential Pesticides Measured from Floor Wipes,” was conducted as a collaboration between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Housing and Urban Development. Five hundred randomly selected homes were sampled using alcohol wipes to collect dust from hard surface floors, mostly kitchen floor surfaces. The swipes were analyzed for 24 currently and previously use residential insecticides in the organochlorine, organophosphate, pyrethroid and phenylpyrazole classes, and the insecticide synergist piperonyl butoxide. Researchers found that currently used pyrethroid pesticides were, not surprisingly, at the highest levels with varied concentrations. Fipronil and permethrin, both currently used, were found in 40 percent and 89 percent of homes respectively. However, the researchers found that long discontinued pesticides like DDT and […]

(Beyond Pesticides, June 16, 2009) A study involving 678 individuals who apply pesticides, culled from a U.S. Agricultural Health Study of over 50,000 farmers, recently found that exposure to certain pesticides doubles one’s risk of developing an abnormal blood condition called MGUS (monoclonal gammopathy of undetermined significance) compared with individuals in the general population. The disorder, characterized by an abnormal level of a plasma protein, requires lifelong monitoring as it is a pre-cancerous condition that can lead to multiple myeloma, a painful cancer of the plasma cells in the bone marrow. The study will appear in the June 18 issue of Blood, the official journal of the American Society of Hematology. “Our study is the first to show an association between pesticide exposure and an excess prevalence of MGUS,” said lead author Ola Landgren, M.D., Ph.D., of the National Cancer Institute (NCI), which is part of the National Institutes of Health, U.S. Department of Health and Human Services. “This finding is particularly important given that we recently found in a large prospective cancer screening study that virtually all multiple myeloma patients experienced a MGUS state prior to developing myeloma.” “As several million Americans use pesticides, it’s important that the risks […]

(Beyond Pesticides, June 4, 2009) Five onion growers in the state of Oregon have been issued civil penalties totaling $180,000 by the Oregon Department of Agriculture (ODA) for using pesticide products not approved for onions. According to the department, the violations resulted from gross negligence and willful misconduct by the pesticide users, who were fined the maximum penalty. The penalties reflect the new broader authority to impose higher penalties for pesticide violations. The sanctions levied in this case are as a result of the use of the new authority granted to the ODA by the 2007 Legislature in fining Oregon growers $10,000 per violation. The department must determine a violation was willful and negligent to issue the $10,000 maximum fine. The previous maximum fine in Oregon was $1,000 for a first violation and $2,000 for a repeat violation. The Oregon growers were fined the maximum in 18 infractions. ODA tested 86 samples of soil, weeds, onion foliage and bulbs from 60 fields in uncovering 18 positive tests. The investigations were initiated based on a tip. The pesticides, bentazon (trade name Basagran) and carbofuran (trade name Furadan), were illegally used on 18 fields during the 2008 growing season, and were found […]

(Beyond Pesticides, May 29, 2008) The Environmental Protection Agency (EPA) announced May 27, 2009 modified safety measures for soil fumigant pesticides, falling short of safety advocate efforts to adopt more stringent use restrictions and chemical bans. The new regulations follow a July 10, 2008 proposed rule, which resulted from three years of deliberation. Safety advocates said last July that while substantially better than the past, the proposed regulation fell short in protecting people, workers and the environment and from that perspective this weeks regulation is a disappointment. Advocates believe that the country can do better to phase out uses of highly hazardous chemicals that have devastating impact on exposed workers and communities in which they are used, and advance green technologies and organic practices. Fumigants, which are among the most toxic chemicals used in agriculture, are gases or liquids that are injected or dripped into the soil to sterilize a field before planting. Even with plastic tarps on the soil, fumigants escape from the soil and drift through the air into schools, homes, parks and playgrounds. Strawberries, tomatoes, peppers, carrots and potatoes are some of the major crops for which fumigant use is high. The agency says these measures will […]

(Beyond Pesticides, May 28, 2009) Two commonly used herbicides, pendimethalin and EPTC, show a statistically significant exposure-response association with pancreatic cancer. The new study, “Agricultural Pesticide Use And Pancreatic Cancer Risk In The Agricultural Health Study Cohort,” published earlier this month in the International Journal of Cancer, is a case-control study of pesticide applicators and their spouses in Iowa and North Carolina. After controlling for age, smoking and diabetes, the study finds a three-fold increased risk with lifetime pendimethalin use and a two-and-a-half-fold increased risk with lifetime use of EPTC when compared to those that never used the chemicals. Among the 24 pesticides examined, having ever used one of five pesticides (trifluralin, chlorimuron-ethyl, pendimethalin, EPTC or heptachlor) shows at least a 40 percent excess risk of pancreatic cancer. According to the U.S. EPA’s pesticide sales and usage statistics, pendimethalin is the third most commonly used home and garden (and other non-agricultural use) herbicide and the 7th most commonly used herbicide in agriculture, totaling 21-30 million pounds applied annually in the U.S. Pendimethalin is listed by the U.S. EPA as a Group C – Possible Human Carcinogen and is a suspected endocrine disruptor. Pendimethalin has been found to cause central nervous […]

(Beyond Pesticides, May 27, 2009) A recent, extensive study which investigated a variety of different chemicals, including organochlorine pesticides, in animal tissues reveals that marine mammals harbor high concentrations of hazardous chemicals in their brains. The results lay the groundwork for understanding how environmental contaminants influence the central nervous system of marine mammals. The study entitled “Organohalogen contaminants and metabolites in cerebrospinal fluid and cerebellum gray matter in short-beaked common dolphins and Atlantic white-sided dolphins from the western North Atlantic” is the first of its kind to find toxic chemicals in the brains of marine mammals. The study identified several contaminants including organochlorine pesticides like DDT, polychlorinated biphenyls (PCBs) and flame retardants in the cerebrospinal fluid and cerebellum gray matter of several species of marine mammals including the short-beaked common dolphins, Atlantic white-sided dolphins and the gray seal. PCBs were found in alarmingly high concentrations. Researchers found parts per million concentrations of PCBs in the cerebrospinal fluid of a gray seal. “We found parts per million concentrations of hydroxylated PCBs in the cerebrospinal fluid of a gray seal. That is so worrisome for me. You rarely find parts per million levels of anything in the brain,” remarked researcher, Eric Montie, […]

(Beyond Pesticides, May 26, 2009) On May 19, 2009, the American Academy of Environmental Medicine (AAEM) released a position paper on genetically engineered (GE) foods stating that, “Genetically engineered foods pose a serious health risk,” and calling for a moratorium on GE foods. Citing several animal studies, the AAEM concludes “there is more than a casual association between genetically engineered foods and adverse health effects” and that “GE foods pose a serious health risk in the areas of toxicology, allergy and immune function, reproductive health, and metabolic, physiologic and genetic health.” The AAEM’s position paper on genetically engineered foods can be found on its website. “Multiple animal studies have shown that GE foods cause damage to various organ systems in the body,” said Amy Dean, M.D., public relations chair and board member of AAEM. “With this mounting evidence, it is imperative to have a moratorium on GE foods for the safety of our patients’ and the public’s health.” The AAEM calls for: — A moratorium on GE food, implementation of immediate long term safety testing and labeling of GE food. — Physicians to educate their patients, the medical community and the public to avoid GE foods. — Physicians to consider […]

(Beyond Pesticides, May 20, 2009) USDA’s National Agricultural Statistics Service (NASS) will reinstate its annual pesticide reporting survey for the 2009 fruit crop. This decision is a partial reversal of a Bush Administration decision last Spring to cut the entire data collection program that was met with widespread criticism from environmental and agricultural groups, exporters. Funding to reinstate the full program in 2010, which is included in President Obama’s proposed budget, is currently before Congress. The National Agricultural Statistics Service has tracked chemical usage in agriculture since 1990. The program conducts surveys on pesticide usage on agricultural commodities, with surveys for fruits and vegetables conducted on alternating cycles. The fruit chemical use surveys are conducted in the odd numbered years. Apples, cherries, citrus, figs and peaches are just some of the fruits monitored. In May 2008, USDA abruptly halted NASS citing an $8 million program shortfall. Environmental groups wanted the survey reinstated because it contains valuable information about which pesticides are used in sensitive watersheds and which affected public and environmental health. The information was also widely used by universities and food industry researchers to help farmers monitor and reduce the amount of pesticides they use. A coalition of 44 […]

(Beyond Pesticides, May 19, 2009) Nearly six months after federal scientists began issuing restrictions to protect salmon and steelhead in the Pacific Northwest and California, the U.S. Environmental Protection Agency (EPA) has yet to take even the first step toward implementing these protections. This delay follows almost a decade of legal wrangling in which a coalition of environmental and fishing groups, led by the non-profit public interest law firm Earthjustice, won a court order. Tell EPA to stop its foot-dragging and protect salmon and steelhead from toxic pesticides. The six pesticides that scientists have reviewed so far are some of the most dangerous chemicals used today. All six””chlorpyrifos, diazinon, malathion, carbaryl, carbofuran, and methomyl””are neurotoxic and pose serious risks to both humans and wildlife. While many of these pesticides have been phased out for residential use, they continue to expose wildlife and farmworkers through their use in agriculture. Thirty-one more chemicals will undergo review by scientists at the National Marine Fisheries Service (NMFS) in the next three years. The new restrictions require EPA to prohibit application of the six pesticides in or near salmon and steelhead habitat. They also require EPA to prohibit application when the weather may cause the […]

(Beyond Pesticides, May 13, 2009) Last week, nine new hazardous chemicals were added to the list of chemicals to be banned under the 2001 Stockholm Convention on Persistent Organic Pollutants. Lindane, a pesticide commonly used in head lice treatments in the U.S. and whose use has already been banned in many countries, was added to the list for phase out. The U.S. Congress has never ratified the Stockhom Convention because of controversy associated with ratification legislation that would weaken federal pesticide law rather than adhere to more protective international standards. Meanwhile, environmental and public health groups in the U.S. have been urging U.S. officials to ban lindane due to its toxic and bioaccumulative effects. More than 160 governments (including those countries that have ratified the Stockholm Converntion) agreed last Saturday to include the nine pesticides and industrial chemicals to the list of 12 other persistent organic pollutants (POPS) in order to strengthen a global effort to eradicate some of the most toxic chemicals known to humankind. The nine chemicals are: ”¢ alpha hexachlorocyclohexane – produced as an unintended byproduct of lindane; ”¢ beta hexachlorocyclohexane -produced as an unintended byproduct of lindane; ”¢ hexabromodiphenyl ether and heptabromodiphenyl ether- used in flame […]

(Beyond Pesticides, May 12, 2009) The Environmental Protection Agency has revoked regulations that permit residues of the pesticide carbofuran in food. This follows a voluntary withdrawl of 22 uses by the chemical’s manufacturer FMC Corporation in Sepember 2008. Carbofuran is a toxic insecticide that does not meet current U.S. food safety standards. EPA’s action will eliminate residues of carbofuran in food, including all imports, in a move to protect people, especially children, from dietary hazards. The action will also force the removal this pesticide from the market. The final carbofuran tolerance rule becomes effective December 31, 2009, a time frame that EPA says growers need to use up existing stocks and transition to alternatives. Phase out periods of known hazards (without notice to the public at point of sale) have long been criticized by adocates who argue that recalls be adopted in similar fashion to other consumer products that are pulled off the market at the time a danger is defined. EPA is proceeding to cancel the remaining carbofuran registrations, or licenses, which will address risks to pesticide applicators and birds in treated fields. In 2006, EPA identified significant dietary, ecological and worker risks from the use of carbofuran and […]

(Beyond Pesticides, May 8, 2009) The United Nations Environment Programme (UNEP) and the World Health Organization (WHO), in partnership with the Global Environment Facility, have announced a renewed international effort to combat malaria with an incremental reduction of reliance on the synthetic pesticide DDT. As recently as two years ago, WHO was criticized for promoting DDT as the answer for malaria control in Africa, leading activists to call for increased use of alternatives. DDT has been recognized as a significant human and environmental health risk, including increased risk of breast cancer a wealth of other health concerns, and have built up in waterways and, in particular, the arctic. Now, ten projects, all part of the global program “Demonstrating and Scaling-up of sustainable Alternatives to DDT in Vector Management,” involving some 40 countries in Africa, the Eastern Mediterranean and Central Asia, are set to test non-chemical methods ranging from eliminating potential mosquito breeding sites and securing homes with mesh screens to deploying mosquito-repellent trees and fish that eat mosquito larvae. The new projects follow a successful demonstration of alternatives to DDT in Mexico and Central America. There, pesticide-free techniques and management regimes have helped cut cases of malaria by over 60 […]

(Beyond Pesticides, May 6, 2009) The U.S. Environmental Protection Agency (EPA), in consultation with the U.S. Fish and Wildlife Service (USFWS), is imposing use restrictions for the insecticide methoxyfenozide on cranberries in Wisconsin because of its potential effect on the Karner Blue butterfly. The Karner Blue butterfly is a federally listed endangered species. It remains to be seen whether, short of a ban, the complex and difficult to enforce restrictions on use and application methods will adequately protect the endangered species. The limitations for methoxyfenozide are contained in a series of county-specific Endangered Species Protection Bulletins (Bulletins) as part of EPA’s Endangered Species Protection Program (ESPP). EPA entered into consultation with USFWS after determining that use of methoxyfenozide on cranberries in Wisconsin may affect the listed Karner Blue butterfly. USFWS recommended a number of use limitations that, when implemented, should result in use that is not likely to adversely affect the Karner Blue butterfly, according to the bulletin. Limitations include not applying the pesticide within the designated pesticide use limitation area, ground applications- only which must be made using a drift retardant and nozzles, and when the wind speed is between 2-10 mph. These limitations are effective within specific areas […]
