(Beyond Pesticides, December 6, 2013) In a new study exploring gene-environment interactions, researchers find that individuals with a genetic mutation linked to Parkinson’s disease are more likely to develop the neurodegenerative disease if they are exposed to pesticides. The study, Isogenic Human iPSC Parkinson’s Model Shows Nitrosative Stress-Induced Dysfunction in MEF 2-PGC1α Transcription, identifies the molecule that protects neurons from pesticides, ties genetic mutation to pesticide exposure, and demonstrates that low dose exposure can cause Parkinson’s disease. The study, conducted by researchers at the Massachusetts Institute of Technology and the Sanford-Burnham Medical Research Institute in La Jolla, CA, supports previous epidemiological and animal studies that demonstrate the link between pesticide exposure and neurological damage, using human stem cells as a model. “For the first time, we have used human stem cells derived from Parkinson’s disease patients to show that a genetic mutation combined with exposure to pesticides creates a ‘double hit’ scenario, producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death,” says lead author Stuart Lipton, M.D., Ph.D., professor and director at the Sanford-Burnham’s Medical Research Institute. Using skin cells from Parkinson’s patient who already possess the genetic mutation linked to the disease, researchers transformed […]

(Beyond Pesticides, December 4, 2013) The U.S. Department of Justice filed a motion in federal court asking a judge to dismiss a lawsuit alleging that the U.S. Environmental Protection Agency (EPA) has failed to uphold environmental justice protections under civil rights law. EPA previously found that Latino schools in California disproportionately suffer from exposure to pesticides due to spraying near their schools, but has yet to adequately remedy these risks, prompting parents to file a civil rights complaint. The schools are near crop fields where toxic fumigants are routinely sprayed and drift off agricultural fields to the nearby community. More than a decade after Latino parents first filed a civil rights complaint with EPA detailing the dangerous levels of pesticides at Latino public schools throughout California, parents on Aug. 23, 2013 filed a lawsuit against EPA to force the agency to protect the civil rights of hundreds of Latino children. The parent say that  ongoing pesticide monitoring set up by the California Department of Pesticide Regulation (CDPR) has not protected children from excessive exposure to pesticides.  The case argues that the Latino community did not receive due process and that EPA’s agreement with CDPR does not prevent schools from pesticide […]

(Beyond Pesticides, December 3, 2013) On Sunday, December 1, 2013 the European Union (EU) took critical steps to protect pollinators from the hazards associated with the use of neonicotinoid pesticides. Despite attempts by agrichemical corporations, including Bayer, and Syngenta,  to delay or reverse the decision, the two-year, continent-wide ban on bee-harming pesticides has gone into effect. However, what’s happening on the other side of the Atlantic is part of a larger story that raises serious concerns for the future of our food. In the United States, the Environmental Protection Agency (EPA), under the direction of Administrator Gina McCarthy, has put forth inadequate label changes that do not protect pollinators. With the support of  over 60 organizations, Beyond Pesticides has helped launch a coalition-based  national advertising campaign to raise awareness of pollinator declines and urge EPA to stop stalling by enacting substantive restrictions on the use of bee-harming pesticides. Go to save-bees.org to lend your support to these efforts. Neonicotinoids, a relatively new class of pesticides, are often used as a seed coating on agricultural crops. Studies have found that honey bees are exposed to high concentrations of neonicotioid pesticides through the dust that is kicked up when coated […]

(Beyond Pesticides, December 2, 2013) Today, Beyond Pesticides, Center for Food Safety and Pesticide Action Network, supported by Ceres Trust and joined by more than 60 other organizations, launched a national media campaign to bring attention to the severity of pollinator declines due in part to the use of bee-harming pesticides. The campaign launch was timed to coincide with the beginning of the European Union’s two-year moratorium on three of the most potent neonicotinoids, which began yesterday. See the ad here. For action item related to this campaign, go to www.save-bees.org. For more on Beyond Pesticides’ BEE Protective campaign, go to www.BEEprotective.org. As part of the national media campaign, full page ads were released in seven newspapers today, including the New York Times, citing the urgency and impact of bee declines and encouraging the public to call on EPA to take action. “We hope this national media campaign will spur public action to combat this major threat to the environment and to our food system. We must protect bees and other pollinators from these harmful pesticides that EPA has so far failed to safeguard them from,” said Larissa Walker, policy and campaign coordinator for Center for Food Safety. Never before […]

(Beyond Pesticides, November 25, 2013) With nearly all the votes counted for Washington State’s Initiative 522, results show the measure defeated by a razor thin margin. After somber reports on Election Day had the measure trailing by 11%, supporters of I-522 urged patience as ballots continued to stream in (Washington runs an all-mail voting system). The race tightened up significantly, but ultimately succumbed to a 49%Y-51%N margin. Despite the results, Washington State’s initiative made incredible progress at raising awareness of the adverse health and environmental impacts associated with genetically engineered (GE) agriculture. A number of factors also worked against the Yes campaign during the final weeks leading up to Election Day, including an enormous influx of money from agrichemical companies and food manufacturers, which financed an advertising blitz claiming the initiative would raise the cost of food. The placement of the measure on an “off-year” election also drove down voter turnout. Yeson522 co-chair Trudy Bialic explains, “There was lower than expected voter turnout this year. Despite being outspent 3-to-1, we are projecting winning 49% of the vote. We are disappointed with the results, but the polling is clear that Washingtonians support labeling and believe they have a right to know. […]

(Beyond Pesticides, November 25, 2013) The Oregon Department of Agriculture (ODA) has restricted two pesticide products linked to massive bee die offs experienced in Oregon earlier this year. Both pesticides are neonicotinoid chemicals that are extremely harmful to bees. Though these restrictions are an important step in protecting bee health, the new rules will still not limit all of the uses of these chemicals that can harm pollinators. ODA placed restrictions on dinotefuran and imidacloprid, banning their use  on linden trees, basswood and other trees of the Tilia genus. Pesticide products that contain these active ingredients are now required to have Oregon-specific labels. This is only the second time in the past ten years that ODA has regulated pesticides more strictly than federal standards. These new restriction comes after ODA adopted a temporary rule in June that limited the use of 18 pesticide products that contained diontefuran. That rule was set to expire next month. States and local jurisdictions  have authority under the nation’s pesticide registration law, the  Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), to adopt more stringent pesticide use restrictions than the federal government. However, after the U.S.  Congress rejected proposals to preempt local authority and the Supreme […]

(Beyond Pesticides, November 22, 2013) The U.S. Environmental Protection Agency (EPA) Assistant Administrator of the Office of Chemical Safety and Pollution Prevention, James Jones, testified before the House Subcommittee on Environment and the Economy last week. The subject of Jones’ testimony: EPA’s informal observations on the proposed Chemical Safety Improvement Act (CSIA). Introduced this past April, the CSIA seeks to reform the severely outdated and ineffective Toxics Substances Control Act (TSCA), the nation’s primary chemical safety law. Adopted in 1976, TSCA established an inventory and notification framework to monitor and assess the commercial production and importation of chemicals. Excluding large swaths of chemicals (such as pesticides and drugs) and placing the burden on EPA to demonstrate unreasonable risks to health or the environment, TSCA has done little to protect the public from or enable EPA to restrict the uses of the more than 84,000 chemicals in the marketplace today. As one 2009 Government Accountability Office (GAO) report noted, “Since 1976, EPA has issued regulations to control only five existing chemicals.” Assistant Administrator Jones’s testimony was quick to point out TSCA’s many flaws, including the grandfathering in of 60,000+ chemicals without any kind of testing and EPA’s inability to require testing […]

(Beyond Pesticides, November 21, 2013) Scientists in France and at the University of Calgary say that nitrogen fertilizer applied to crops lingers in the soil and for decades leaches toward groundwater —much longer than previously thought. The study was led by researcher Mathieu Sebilo, Ph.D. at the UniversitĂ© Pierre et Marie Currie in Paris, France, and by Bernhard Mayer, Ph.D. in the U of C’s Department of Geoscience, and included several research organizations in France. The study, Long-term fate of nitrate fertilizer in agricultural soils, was published in the Proceeding of the National Academy of Sciences in the U.S. in October. The study shows that the loss of synthetic nitrogen (N) fertilizer in groundwater occurs at low rates over many decades, which means it could take years to reduce nitrate contamination in groundwater, including in aquifers that supply drinking water. The researchers recommend that as a result of the “legacies of past applications of synthetic fertilizers in agricultural systems,” mitigation or restoration measures must take into account this delay. In fact, the scientists found that three decades after application of isotopically labeled fertilizer N to agricultural soils in 1982 12—15% of the fertilizer-derived N is still residing in the soil […]

(Beyond Pesticides, November 20, 2013) Illinois public health officials say that more than 200 Illinois schools and day care centers have failed to comply with the most basic of the state’s pest management regulations, and for the first time could face fines if they do not comply. According to the Illinois Department of Public Health (IDPH), the state’s IPM regulations, including the requirements for reporting how pests are managed, are designed to protect children in day care centers and schools from unnecessary applications of pesticides. Last Friday, the Illinois Department of Public Health announced that it is ramping up its efforts to educate day care centers and schools about the rules aimed at reducing and managing pests in light of widespread non-compliance with pest management regulations in public schools and day care centers. State law requires public schools and licensed day care centers to file an Integrated Pest Management (IPM) form with the department to document how school officials plan to implement IPM. The state’s Structural Pest Control Act (Act), [225 ILCS 235] requires public schools and licensed day care centers to, when economically feasible, develop and implement an IPM program and resubmit their plans every 5 years. Additionally, all […]

(Beyond Pesticides, November 18, 2013) Kauai made history in Hawaii and worldwide on Saturday when it enacted a law to force public disclosure of  large scale production of  experimental genetically engineered organisms and pesticide use.  Using the  authority vested in local political subdivisions by the state’s constitution, the law seeks to “to establish provisions to inform the public, and protect the public from any direct, indirect, or cumulative negative impacts on the health and the natural environment of the people and place of the County of Kaua”˜i, by governing the use of pesticides and genetically modified organisms.” The Council, with an outpouring of community support, voted 5-2 to override the Mayor’s veto of Bill 2491,  introduced by Council  Member Gary Hooser. The bill  was originally passed by the Council on October 16, 2013 by a 6-1 vote. According to the Honolulu Star Advertiser newspaper, a Syngerta attorney said, “There will definitely be a lawsuit.” The newspaper cites Syngenta, DuPont Pioneer, Dow AgroSciences, BASF, and Kauai Coffee, the largest coffee grower in the state, as being affected by the legislation. In addition to the public disclosure provisions that take effect in nine months, the law requires an  Environmental and Public Health […]

(Beyond Pesticides, November 15, 2013) Recommended measures to reduce Lake Erie’s phosphorous, a fertilizer ingredient that feeds algae and steals aquatic oxygen, was released Wednesday by the Lake Erie Task Force II. The collaboration of officials, scientists, and interest groups identified agriculture as the primary contributor to phosphorous loading in Lake Erie, recommending that the nutrient runoff into northwestern Ohio tributaries and to the lake be cut by 40 percent. Fertilizer runoff not only causes unsightly and odiferous algal blooms, it can also severely harm aquatic wildlife. Once algae dies off, aerobic bacteria consume the dead algae resulting in dangerously low oxygen “dead zones.” Lake Erie is particularly prone to algal blooms in part because it is the southern-most, shallowest and warmest of the Great Lakes, but also because surrounded by prime agricultural land. The task force’s report contains 20 recommendations for reducing phosphorous inputs into Lake Erie, including continued nutrient monitoring, developing dedicated funds for research, updating the phosphorous index farmers use to guide their fertilizer applications, promoting management practices that support living roots year round, and avoiding fertilizer application on frozen ground or before rainy weather. Unfortunately, the task force is recommending strictly voluntary measures and many environmental […]

(Beyond Pesticides, November 13, 2013) As the world sheds tears from reading the reports of human suffering and looks on in horror at the pictures of devastation caused by Typhoon Haiyan, the debate of whether increased occurrences of super-storms like Haiyan are just over the horizon because of man-made climate change have also taken up residence in the headlines. Coupled by coverage of the 19th session of the Conference of the Parties to the U.N. Framework Convention on Climate Change and the leak of a draft summary of the Intergovernmental Panel on Climate Change’s latest report on the impacts of global warming, the world is clearly paying attention. As the wide array of demonstrated effects and impacts of climate change are discussed on the world stage and world leaders attempt, once again, to create a meaningful plan to mitigate risks and even potentially avoid some of the most extreme threats, an important and even more deadly consequence of climate change lurks in the background: increased toxic chemical exposure. In a collection of studies and scientific reviews released earlier this year in Environmental Toxicology and Chemistry, scientists investigated a wide range of global climate change issues and toxicological impacts on the […]

(Beyond Pesticides, November 12, 2013) On November 6 BASF, a German agrochemical company, took legal action in the General Court of the European Union (EU) to challenge the EU Commission’s decision to restrict seed treatment uses of the insecticide fipronil. BASF joins chemical companies Bayer and Syngenta in challenging the EU’s decision to restrict the use of certain pesticides that are harmful to pollinators. The EU Commission’s decision to restrict the use of fipronil in July came after the Commission’s landmark decision announcing a two-year continent-wide ban  on the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam. The pesticides have been linked to the decline in bee populations.  Twenty-three European Union Member States supported the fipronil restriction, two Member States voted against, and three Member States abstained during the standing committee vote. BASF argued that its  legal action against the EU is based on a disproportionate application of the precautionary principle. However, overwhelming scientific evidence supports the position that fipronil is highly toxic to bees. Fipronil, a phenyl pyrazole broad-spectrum insecticide, was first introduced in the U.S. in 1996 for commercial turf and indoor pest control and is highly toxic to bees. A recent investigation reveals that fipronil is responsible for the […]

(Beyond Pesticides, November 8, 2013) In a new study on ecosystems in the Midwest, scientists suggest that once-fertile landscapes dominated by tall grass prairies and supported by microbial biodiversity have been destroyed due to decades of agricultural production. The study, Reconstructing the Microbial Diversity and Function of Pre-Agricultural Tall Grass Prairie Soils in the United States, published in the journal Science, demonstrates the crucial role soil microbial diversity plays in ecosystem stability and health. Although soil microbes are inherently important for the breakdown of organic matter, the cycling of nutrients, as well as plant productivity, previous research has narrowly focused on the role of nitrogen fixing root fungi, rather than broader aspects of soil microbial diversity. Thus, this new study represents one of the first to delve into the importance of soil microorganisms in ecosystem restoration projects. By comparing soil samples from 31 uncultivated prairie sites, such as cemeteries and national parks, lead author Noah Fierer, PhD., at University of Colorado at Boulder and colleagues were able to identify microbes that likely inhabited the prairies prior to agricultural production. The study found that small changes to the abundance of Verrucomicrobia ””until now a poorly researched soil bacterium”” were the primary […]

(Beyond Pesticides, November 7, 2013) A study released this week established a strong connection between endometriosis and exposure to two dangerous pesticides: lindane and mirex. While the results are not surprising given past connections between these pesticides and their endocrine-disrupting effects, this new study, Organochlorine Pesticides and Risk of Endometriosis: Findings from a Population-Based Case-Control Study, is one of the first to examine the association between organochlorine pesticides (OCPs) and endometriosis, one of the most common gynecological diseases, in women in the general population. The study’s authors, Kristen Upson, Ph.D. et al,  explained to Environmental Health Perspectives, “Our study suggests that exposure from extensive past use of environmentally persistent OCPs in the United States, or present use in other countries may impact the health of the current generation of reproductive-age women with regard to a hormonally-mediated disease.” In conducting the study, researchers selected a group of women with surgically-confirmed cases of endometriosis from the greater Pacific Northwest area. This group of women was then divided into four groups, based on the level of pesticide in each woman’s blood. Women in the second-highest exposure group for beta-hexacyclochlorohexane (beta-HCH), a byproduct of lindane, had a 70 percent greater risk of endometriosis than […]

(Beyond Pesticides, November 6, 2013) A federal district court approved a settlement Monday requiring the U.S. Fish and Wildlife Service to better protect California red-legged frogs from seven common pesticides known to be highly toxic to amphibians. The settlement gives the agency two years to prepare “biological opinions” under the Endangered Species Act (ESA) to analyze pesticide use in and near the frog’s aquatic and upland habitats.  A 2006 legal settlement secured by the Center for Biological Diversity (CBD) required the U.S. Environmental Protection Agency (EPA) to assess pesticide impacts on red-legged frogs and to then formally consult with the Fish and Wildlife Service (FWS) under the ESA. The EPA’s assessments found that widespread use of pesticides is likely harming red-legged frogs and the court ordered temporary pesticide use restrictions that remain in effect today. EPA determined that 64 other pesticides are “likely to adversely affect” or “may affect” red-legged frogs. Despite the EPA’s findings, however, FWS and EPA failed to complete the required consultation, resulting in the litigation by CBD that culminated in Monday’s settlement. The court order gives FWS two years to complete biological opinions for seven pesticides: glyphosate, malathion, simazine, pendimethalin, permethrin, methomyl and myclobutanil. This […]

(Beyond Pesticides, November 4, 2013)  The hard-fought victory of Kauai residents to protect their homes, children, and natural environment from the chemical and agricultural industry’s excessive and secretive applications of pesticides was threatened last week.  Bill 2491,  passed earlier this month  and crafted to  rein in the ecosystem-threatening development of genetically  engineered crops  with their excessive reliance on pesticides, has been vetoed by Kauai’s Mayor Bernard Carvalho. The bill established much-needed disclosure, notice, and reporting mandates for commercial-scale pesticide applications, required pesticide application buffer zones for schools, hospitals, residences, public spaces, waterways, and parks, and mandated that the County perform and Environmental and Public Health Impacts Study (EPHIS). (See previous Daily News coverage for a more expanded history and discussion of the evolution of the bill.) A critical component of the bill is the inclusion of a penalties provision. Acting as a strong industry- incentive to comply with the bill’s mandates and protective measures, the penalties provision permitted civil fines of between $10,000 and $25,000 per day per violation and potential misdemeanor criminal sanctions. Mayor Carvalho defended his veto decision by saying that the bill ran afoul of a number of laws, including the Right to Farm Act, according […]

(Beyond Pesticides, November 1, 2013) Insecticides commonly used in homes and schools are associated with behavioral problems in children, according to a recent study by Canadian researchers. The study investigates exposure to pyrethroid pesticides, used in more than 3,500 products, including flea and tick controls, cockroach sprays, and head lice controls. The study, Urinary metabolites of organophosphates and pyrethroid pesticides and behavioral problems in Canadian children, published in the journal Environmental Health Perspectives, raises serious concerns about the impact of pyrethroids, which are increasingly used as a replacement for organophosphates. This study uses data from the Canadian Health Measures Survey (2007-2009), a nationally representative survey, so researchers are able to apply these findings to the entire population of Canadian children. In a previous study among U.S. children, researchers at the National Health and Nutrition Examination Survey (NHANES) examined the metabolites of pyrethroids in children below the age of six. Similarly, they found pyrethroid insecticides in more than 70 percent of the samples, concluding that children had significantly higher metabolite concentrations than those of adolescents. Together these studies demonstrate that exposure is widespread, with real impacts to human health. In the recent study, researchers analyzed organophosphate and pyrethroid metabolites in the […]

(Beyond Pesticides, October 31, 2013) Bats get a bad rap on Halloween with their image synonymous with blood-sucking vampires; however, the real scary thing about bats is that they are disappearing due to a myriad of threats, including pesticides, habitat destruction, and the horrible white-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus (Geomyces) destructans. Researchers are reporting an even bleaker picture, finding very little evidence of what might stop the disease from spreading further and persisting indefinitely in bat caves. The new study, from researchers at the Illinois Natural History Survey at the University of Illinois, found that the fungus can make a meal out of just about any carbon source likely to be found in caves, said graduate student Daniel Raudabaugh, who led the research under the direction of survey mycologist Andrew Miller, Ph.D. The study, Nutritional Capability of and Substrate Suitability for Pseudogymnoascus destructans, the Causal Agent of Bat White-Nose Syndrome is published in PLOS One. “It can basically live on any complex carbon source, which encompasses insects, undigested insect parts in guano, wood, dead fungi and cave fish,” Mr. Raudabaugh said. “We looked at all the different nitrogen sources and found that basically it can […]

(Beyond Pesticides, October 30, 2013) Once again, a bipartisan group of U.S. Senators is urging Farm Bill conference committee members to accept a provision that would eliminate what they call a redundant permitting requirement for pesticide users. H.R. 935: Reducing Regulatory Burdens Act of 2013 is similar to a previous piece of legislation that was passed in the U.S.  House of Representatives  in 2011 to eliminate the requirement that pesticide applicators obtain Clean Water Act (CWA) permits (known as National Pollutant Discharge Elimination  System (NPDES) permit)  for applications where pesticides could be discharged into water. A  bipartisan group of  Senators hope to use the Farm Bill to eliminate permitting requirement, continuing to believe the myth that permits burden farmers and applicators. The Senate and House are now in a conference committee to work out the details of a new Farm Bill to reauthorize the current law. A dozen Senators, led by Sen. Kay Hagan, D-N.C., have asked House and Senate negotiators to do away with the CWA regulation of pesticide discharges as they consider a compromise Farm Bill. Legislation eliminating the CWA permitting requirement last year passed the House, but the move to strip the U.S. Environmental Protection Agency (EPA) […]

(Beyond Pesticides, October 29, 2013) Early-life exposure to the herbicide atrazine makes frogs more susceptible to death from chytrid (Batrachochytrium dendrobatidis), a fungal disease implicated in amphibian declines across the globe. The research, Early-life exposure to a herbicide has enduring effects on pathogen-induced mortality, published in the Proceedings of the Royal Society B and led by University of South Florida (USF) biologist Jason Rohr, Ph.D, provides critical information for scientists hoping to stem the global demise of amphibian populations. “Understanding how stressors cause enduring health effects is important because these stressors might then be avoided or mitigated during formative developmental stages to prevent lasting increases in disease susceptibility,” Dr. Rohr explains. Researchers exposed tadpoles to atrazine at levels found in the environment for a period of  six days during the animal’s development, in combination with exposure to chytrid fungus (linked to worldwide amphibian decline), resulted in increased mortality 46 days later. According to the study, “[E]arly-life exposure to atrazine altered growth and development, which resulted in exposure to chytrid at more susceptible developmental stages and sizes, and reduced tolerance of infection, elevating mortality risk at an equivalent fungal burden to frogs unexposed to atrazine. Moreover, there was no evidence of […]

(Beyond Pesticides, October 28, 2013) Scientists at Washington State University (WSU), in a laboratory study,  determined that exposure to the insecticide DDT ””banned in the U.S. since 1972, but still used today in developing countries for malaria abatement programs””impacts multiple generations, ultimately contributing to obesity three generations down the line. The study, published in the journal BMC Medicine, provides the scientific community with new information on multi-generational impacts of pesticide exposure. Lead researcher Michael Skinner, PhD., professor of biological sciences at WSU, and colleagues exposed pregnant rats to DDT to determine the long-term impacts to health across generations. The study, Ancestral dichlorodiphenyltrichloroethane (DDT) exposure promotes epigenetic transgenerational inheritance of obesity, finds that the first generation of rats’ offspring developed severe health problems, ranging from kidney disease, prostate disease, and ovary disease, to tumor development. Interestingly, by the third generation more than half of the rats have increased levels of weight gain and fat storage. In other words, the great grandchildren of the exposed rats are much more likely to be obese. “Therefore, your ancestors’ environmental exposures may influence your disease development even though you have never had a direct exposure,” the study finds. Previous studies have demonstrated that exposure to […]

(Beyond Pesticides, October 25, 2013) A report released by a Johns Hopkins University panel reached two disturbing conclusions this week: (1) the United States population is continuing to face unnecessary public health risks because of the use of antibiotics in livestock production, and (2) the Food and Drug Administration (FDA) and other agencies are not likely to take meaningful action to address this risk. The report, Industrial Food Animal Production in America: Examining the Impact of the Pew Commission’s Priority Recommendations, follows five years after the Pew Commission on Industrial Farm Animal Production (PCIFAP) released its previous investigative report and recommendation to, among other actions, phase out and then ban nontherapeutic (or subtherapeutic) uses of antibiotics in industrial food animal production. The consequences of not following through on this recommendation would place the public at risk of increased pools of antibiotic-resistant superbugs. These superbugs threaten at least 2 million people each year and at least 23,000 people die each year as a direct result of these infections.  Many more people die from other conditions that were complicated by an antibiotic-resistant infection. Despite some congressional response  following the release of the 2008 Pew Commission report and a federal court order requiring […]
