(Beyond Pesticides, April 29, 2013) Dow AgroSciences, one of the nation’s largest pesticide makers, along with various food companies, have persuaded several members of Congress to endorse a bill that directs the Environmental Protection Agency (EPA) to reverse a proposed phase out of sulfuryl fluoride, a highly toxic food fumigant and potent greenhouse gas. If passed, the bill would make the U.S. one of only two western nations to allow sulfuryl fluoride on food, increase the number of American children ingesting unsafe levels of fluoride, and create a food poisoning risk for consumers who  purchase food that contains permissible levels of the fumigant. The  Pest Free Food Supply Act, H.R. 1496, sponsored by Rep. Tom Graves (R-GA) and 14 others, seeks to prevent the proposed  phase out  of sulfuryl fluoride from taking effect. The phase out, which EPA proposed in January 2011, was prompted by a  joint petition from the Fluoride Action Network (FAN), Environmental Working Group (EWG) and Beyond Pesticides. In seeking to prevent the phase out from taking effect, the bill’s sponsors have adopted Dow’s widely discredited talking points on the safety and necessity of sulfuryl fluoride fumigation. The public should know: ”¢ Of the few western nations […]

(Beyond Pesticides, April 9, 2013) Last Wednesday, close to a hundred people attended a public hearing at the Riverhead campus of Suffolk County Community College, sponsored by the Department of Environmental Conservation (DEC), to comment on the draft of the Long Island Pesticide Pollution Prevention Strategy. The strategy, which was released in January, is dramatically different than a draft plan DEC had released in 2011. The draft plan had initially received praise from environmental organizations for its “zero tolerance policy”   to ensure certain chemicals did not end up in Long Island’s drinking water. However, the revamped strategy fails to offer any meaningful protective measures or strong pesticide regulations. This is concerning, given trace amounts of metalaxyl, imidacloprid and atrazine have been repeatedly detected in test wells, along with 117 other pesticides detected in Long Island drinking water. State officials argued that pesticide levels in Long Island’s drinking water are far below federal standards. However, the pesticides that have been found in the drinking water have been linked to several health and environmental problems. Because of these health and environmental risks the Citizens Campaign for the Environment, a grassroots organization working in Long Island, has called for DEC to ban […]

(Beyond Pesticides, March 4, 2013) Two studies released on February 28th in the journal Science detail the dramatic decline of wild pollinators and their effectiveness in producing seeds and fruit on crops in comparison to domesticated honey bees. The study conducted on the effectiveness of wild pollinators, which was led by Lucas A. Garibaldi Sc.D. of Universidad Nacional de Río Negro in Argentina, collected data at 600 test fields on all continents except Antarctica for 41 crop systems. These studies come on the heels of a possible suspension of neonicotinoid insecticides, which have been linked to Colony Collapse Disorder (CCD), by states in the European Union. In the United States action currently looks less likely, as the U.S. Environmental Protection Agency (EPA) has moved to register sulfoxaflor, which the agency has classified as “very highly toxic to bees.” These studies note that even though large active colonies of honey bees are useful for pollination, they cannot fully replace the contributions of diverse, wild insects in plant pollinations. Dr. Garbaldi’s study calls for, among other policy recommendations, “consideration of pollinator safety as it relates to pesticide application.” The first of these two studies, led by Laura A. Burkle Ph.D., was titled […]

(Beyond Pesticides, March 1, 2013) In a literature review published in Toxicology last week, researchers found that environmental and occupational pesticide exposure was strongly associated with declines in sperm count. Researchers Sheena Martenies, BS, and Melissa Perry, ScD., MHS., determined that of the 17 studies evaluated, 15 of them reported significant associations between pesticides and semen quality. The researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. Researchers targeted studies on DDT, HCH, and abamectin, grouping pyrethroids and organophosphates by class. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies””only two indicated any changes to sperm shape. These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health. In addition to the U.S. findings,  studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50% between 1940 and 1990, no small amount. These results might not be surprising as […]

(Beyond Pesticides, February 27, 2013) Last week a U.S. Court of Appeals found that pesticide restrictions to protect endangered salmon and steelhead proposed by the National Marine Fisheries Service (NMFS) in its Biological Opinion (BiOp) were “arbitrary and capricious,” supporting Dow AgroSciences LLC and other pesticide makers’ claims that the restrictions were based on “unsupported assumptions and conclusions.” The BiOp concluded that the pesticides chlorpyrifos, malathion and diazinon, three of the most highly toxic pesticides still in use, pose risks to salmon, steelhead and their habitat. In collaboration with NMFS, the U.S. Environmental Protection Agency (EPA) is tasked with implementation of any recommended pesticide restrictions to satisfy the mandate under Section 7 of the Endangered Species Act (ESA). However, to date, EPA has not taken any actions to implement any of the proposed measures to protect endangered salmon and steelhead, in part due to challenges from industry. Dow AgroScience LLC, Makhteshim Agan of North America, Inc., and Cheminova, Inc. USA first filed a suit in 2009 (Dow Agrosciences v. National Marine Fisheries ), challenging the NMFS’ 2008 BiOp to restrict  chlorpyrifos, malathion and diazinon as being based on numerous unsupported assumptions and conclusions, and faulty analyses. The U.S. District Court […]

(Beyond Pesticides, February 21, 2013) On February 6, the U.S. Environmental Protection Agency (EPA) released its preliminary volatilization assessment for the registration review of chlorpyrifos, finding that vapor phase chlorpyrifos may be emitted from treated fields at levels resulting in exposure to children and others who live, work, attend school, or otherwise spend time nearby.  In some circumstances, these bystanders may be exposed to chlorpyrifos and/or the transformation product chlorpyrifos-oxon at concentrations that could cause adverse effects. Citing uncertainties, the agency is requesting comments by March 8, 2013 on the potential risks to children and other bystanders from volatilization of chlorpyrifos from treated crops. EPA’s preliminary volatilization assessment is also in response to a petition filed by the Natural Resources Defense Council (NRDC) and the Pesticide Action Network North America (PAN) in 2007, which requested that the agency revoke all tolerances and cancel all registrations for chlorpyrifos. In a letter to NRDC and to PAN dated January 25, 2013, updating these groups on EPA’s response to their September 12, 2007 joint petition regarding chlorpyrifos, EPA stated that, “This assessment represents a significant advancement in the evaluation of pesticide risks, as it will be the first probabilistic assessment of the risks […]

(Beyond Pesticides, January 15, 2013)  Research published in the journal Environmental Monitoring and Assessment calls into question the value of environmental monitoring, such as water sampling,  on a  fixed date schedule (i.e., once per month), finding that this approach underestimates actual risks. These findings could have a significant impact on how we assess the safety of both endangered species and drinking water supplies. Researchers explain that, although insecticides are applied less often than herbicides and fungicides, they are usually applied in very large amounts when used in response to acute insect infestations. Scientists found that monitoring for insecticides at pre-set intervals, even weekly or daily, did not detect the occurrence of peak concentrations for these chemicals. Co-author of the study, Ralf Shulz, PhD, explains, “Accordingly, by way of example, on the basis of weekly monitoring of a typical agricultural stream none of the total of six insecticide concentration peaks per year described by model calculations is found. Daily sampling detects only two of the six peaks. Only event-related sampling enables the detection of all these peaks.” Authors of the study point to the need for events-related sampling, both to ensure more accurate detections are taken and to reduce costs. Events-related […]

(Beyond Pesticides, November 21, 2012) The National Organic Coalition (NOC) yesterday sharply condemned recommendations contained in the final report of the Advisory Committee on Biotechnology and 21st Century Agriculture (AC21), a group appointed by the U.S. Department of Agriculture (USDA) to address transgenic contamination of organic and non-genetically engineered (GE) crops. Of particular concern in the report is the recommendation that organic and non-GE conventional farmers pay for crop insurance or self-insure themselves against unwanted GE contamination. NOC strongly asserts that this proposal allows USDA and the agricultural biotechnology industry to abdicate responsibility for preventing GE contamination, while making the victim of GE pollution pay for damages resulting from transgenic contamination. “The AC21 report takes responsibility for GE contamination prevention out of the hands of USDA and the biotech industry where it belongs and puts it squarely on the backs of organic and non-GE farmers,” said Andrew Kimbrell, executive director at Center for Food Safety and a NOC member. “This ill-conceived solution of penalizing the victim is fundamentally unjust and fails to address the root cause of the problem – transgenic contamination.” In August 2011, USDA convened AC21 and charged it with identifying compensation mechanisms to address GE contamination. The […]

(Beyond Pesticides, November 1, 2012) Conservation groups and fisherman have filed lawsuits against U.S. Environmental Protection Agency (EPA) demanding that pesticide restrictions be implemented around salmon streams. Regulatory buffers surrounding streams and watersheds have not been fully implemented by EPA, though it is required to by law. The National Marine Fisheries Service (NMFS), which promotes sustainable fisheries, recovery of protected species, and the health of coastal marine habitats, commented that common pesticides should not be sprayed within 500 to 1000 feet of waterways. Its comments focused on the impacts of chlorpyrifos, diazinon and malathion, which jeopardize the health of federally protected salmon species. Despite this and other evidence that supports the need for buffer zones, EPA has withheld action until the 4th U.S. Circuit Court of Appeals resolves the case. EPA is mandated by law to protect dwindling species like salmon under the Endangered Species Act. Salmon, in particular, are a good indicator of how well we are taking care of both the marine and terrestrial ecosystems, because they live in streams, lakes, rivers, estuaries, and open ocean. They are also extremely sensitive to changes in water quality and upstream changes to the river flow, turbidity, and temperature. It goes […]

(Beyond Pesticides, September 10, 2012) Traces of pesticides in drinking water were found in eleven rural elementary schools in Oregon, according to a U.S. Department of Agriculture (USDA) study released on August 30. The study shows a disturbing variety of pesticides that when combined could have dramatic impacts on the health of the children that consume this water on a daily basis. The study found traces of several different types of pesticides in the drinking water of Dixie and Fairplay, the elementary schools that service Corvallis, Oregon. Some of the pesticides that were found in the Dixie school water include atrazine, bromacil, diuron, imidacloprid, metolachlor, norflurazon, and simazine. In the nine other schools that were found to have pesticides in their drinking water, seven different pesticides were found in the water at Applegate Elementary in Eugene, and multiple pesticides were also found in the drinking water of Ontario’s Pioneer and Cairo elementary. Children face unique hazards from pesticide exposure. They take in more pesticides relative to their body weight than adults in the food they eat and air they breathe. Their developing organ systems often make them more sensitive to toxic exposure. The body of evidence in scientific literature shows […]

(Beyond Pesticides, September 5, 2012) A California court has removed aerial spraying from a controversial statewide plan to control the light brown apple moth. However, the court let stand the rest of the large-scale plan implemented by the California Department of Food and Agriculture (CDFA), limiting its duration and requiring a review of the environmental effects if the state proposes to continue the Light Brown Apple Moth (LBAM) Program beyond 2017. While the state cannot use aerial spraying methods, the plan approved by the court permits the use of pesticides to control the moth. In a ruling released last week, Sacramento Superior Court Judge Lloyd Connelly referred to “the experimental nature of the LBAM Program,” observing, “There is no evidence that the Department has been able to identify with any certainty the effectiveness of particular strategies in containing, controlling, suppressing or eradicating LBAM.” The Judge also ruled that, without additional evaluation under California environmental laws, CDFA’s approval of the environmental document would “foreclose the Department from reinstating the aerial releases to the LBAM Plan.” The court rejected a broader claim by a coalition of health and environmental organizations, which challenged CDFA’s failure to disclose or accurately describe all the harms […]

(Beyond Pesticides, August 30, 2012) The U.S. Environmental Protection Agency (EPA) announced on August 17 that it is seeking comments on a proposal developed jointly with the U.S. Department of Agriculture (USDA), the National Marine Fisheries Service (NMFS), and the U.S. Fish and Wildlife Service (FWS) to enhance opportunities for stakeholder input during pesticide registration reviews and endangered species consultations. The proposal specifically emphasizes coordination across federal agencies and expanding USDA’s role, as well as pesticide users to provide current pesticide use information to EPA’s ecological risk assessments. The proposal describes EPA’s plan to reach out to potentially affected pesticide users to discuss the technical and economic feasibility of draft Reasonable and Prudent Alternatives (RPAs) intended to avoid jeopardy to threatened and/or endangered species. It also describes the process by which public comments received on RPAs will be summarized and organized by EPA and provided to the Services, which will prepare a document to be included in the administrative record of the consultation explaining how comments were considered, and if appropriate, how the final biological opinion was modified to address the comments. The Services will provide the document to EPA, and both the Services and EPA will make the document […]

(Beyond Pesticides, August 23, 2012) Two commonly used nanoparticles have a significant impact on the growth and yield of food crops, according to a team of scientists led by University of California Santa Barbara’s Bren School of Environmental Science and Management. The study’s conclusions echo similar research findings that show human and environmental risks from nanoparticles are not fully understood, and conclude that a precautionary approach should be used until their fate and toxicity is better understood. The nanoparticles tested in the PNAS study, “Soybean susceptibility to manufactured nanomaterials with evidence for food quality and soil fertility interruption,” include zinc oxide, found in everyday products such as sunscreen, lotions, and cosmetics, and cerium oxide, used in diesel fuels to increase fuel combustion. Zinc oxide nanoparticles enter agricultural fields through the application of biosolid (sewage sludge) fertilizers, which are composed of dried microbes previously used to process wastewater in treatment plants. Researchers discovered that soybean plants grown in soil containing zinc oxide particles bioaccumulate zinc, taking up the metal and distributing it throughout edible plant tissue. This caused a decrease in the food quality of the soybeans, and researchers indicate that it is uncertain whether the zinc that accumulates in the […]

(Beyond Pesticides, August 15, 2012) After decades of denying Vietnamese requests for assistance in a cleanup, the United States launched its first major effort to address environmental contamination brought on by its use of Agent Orange in the Vietnam War, this according to the New York Times. Agent Orange is a toxic herbicide which contains dioxin —a known carcinogen- used by the U.S. military to defoliate Vietnamese forests, which left a legacy of cancer, birth defects, and environmental contamination, with an estimated 3 million Vietnamese people exposed.

(Beyond Pesticides, August 6, 2012) The Minnesota Supreme Court reversed a ruling that gave organic farmers clear redress and decided that pesticide drift from one farm to another is not trespass, but instead must, in litigation, be found to be negligence or a nuisance. The ruling, while still giving farmers a legal channel to sue on pesticide drift, creates a higher standard for organic farmers to seek relief if their crops are damaged by pesticide drift. The ruling overturns a decision last summer by the state Court of Appeals that said pesticide drifting from its intended farm onto an adjacent organic farm could be considered a trespassing violation. In reversing a 2011 appeals court ruling, the Supreme Court said Minnesota does not recognize trespassing by “particulate matter.” The high court said the earlier appeals court ruling that found otherwise went “beyond our precedent.” The case is that of organic farmers Oluf and Debra Johnson, who sued the Paynesville Farmers Union Cooperative Oil Company in 2009. The Johnsons alleged that the co-op repeatedly sprayed pesticides that drifted onto their fields, preventing them from selling their crops as organic. The Johnsons transitioned their farm to organic in the 1990s to take advantage […]

(Beyond Pesticides, July 23, 2012) The U.S. Environmental Protection Agency’s (EPA) announcement last week of new agricultural risk mitigation measures for the neurotoxic insecticide chlorpyrifos continues to ignore farmworker health and that of their families, as well as the viability of organic farming systems in providing not only safer food, but safer working environments for farmworkers. The new measures, while a step in the right direction to protect vulnerable populations, do not go far enough to address the unreasonable risks associated with the chemical’s widespread continued use. The national pesticide law, the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), requires protection against “unreasonable adverse effects to man or the environment.” In its latest decision, EPA seeks to reduce exposure to “acceptable” risk levels. In this case, the agency is seeking to reduce exposure of bystanders to spray applications. The measures include reductions in aerial application rates of the insecticide and the establishment of mandatory buffers around sensitive sites where bystanders including children are known to suffer exposure. The new mitigation practices include reducing the maximum amount of chlorpyrifos that can be applied per acre using spray applications from 6 pounds/acre to 2 pounds/acre. The new measures also include no-spray buffer […]

(Beyond Pesticides, July 18, 2012) Just as the U.S. Environmental Protection Agency (EPA) opened the federal docket for the registration review of nanosilver, Rice University researchers settled a long-standing controversy over the mechanism by which silver nanoparticles, the most widely used nanomaterial in the world, kill bacteria. The researchers found that the silver ions, rather than the silver particles, have antimicrobial effects on bacteria. However, their work comes with a warning; low doses of nanosilver can make bacteria stronger and more resistant. Silver nanoparticles are used just about everywhere, including in cosmetics, socks, food containers, detergents, sprays and a wide range of other products to stop the spread of germs. Researchers have debated the mechanisms by which nanosilver particles exert toxicity to bacteria and other organisms. They have long known that silver ions, which flow from nanoparticles when oxidized, are deadly to bacteria. In the study, “Negligible Particle-Specific Antibacterial Activity of Silver Nanoparticles,” published in NanoLetters, the researchers explain that the nanoparticles are practically benign in the presence of microbes. But when in soluble ionic form, that is, when activated via oxidation, nanosilver becomes toxic to bacteria. The research team decided to test nanoparticle toxicity in an anaerobic environment —with […]

(Beyond Pesticides, July 5, 2012) After a 2006 cancellation of uses due to unreasonable risks to farmworker health and the environment, and a 6-year phase out scheduled to conclude this September, the U.S. Environmental Protection Agency (EPA) is conducting a risk-benefit analysis to make a determination whether to keep in place or amend the cancellation order for the organophosphate azinphos-methyl (AZM), citing new information on the economic costs of using alternatives. In 2001, EPA found that insecticides azinphos-methyl (AZM) posed unacceptable risks to farmworkers and announced that 28 crop uses were being canceled, seven crop uses were to be phased-out over four years, and eight crop uses were to be allowed to continue under a “time-limited” registration for another four years. Farmworker advocates challenged that decision in federal court citing that EPA failed to take into account the costs of poisoning workers, exposing children, and polluting rivers and streams. A settlement agreement effectively stayed the legal challenge pending EPA’s reconsideration of the “time limited” uses of AZM. In November 2006, EPA decided that AZM poses unreasonable adverse effects and issued a final decision to cancel AZM, but allowed continued use on some fruit crops (apples, cherries, pears) for six more […]

(Beyond Pesticides, May 14, 2012) The U.S. Environmental Protection Agency (EPA) is accepting public comment on several complex regulatory issues related to the agency’s commitment to phase out the toxic fumigant sulfuryl fluoride. At one time EPA had supported sulfuryl fluoride as a replacement for a second fumigant, methyl bromide, which the United States is obligated under international treaty to eliminate due to its contribution to ozone depletion. However, EPA reversed that support once further research and a refined risk assessment established that aggregate exposure to sulfuryl fluoride does not adequately protect the health of certain population subgroups. Although EPA decided unequivocally in 2011 to phase out all food-related uses for sulfuryl fluoride, the current public comment opportunity revisits key elements of that decision and could open the door for an unwarranted and unnecessary extension of this toxic fumigant’s allowance. Initially registered in 1959 to kill termites and other wood-boring pests, sulfuryl fluoride gained attention as a potential alternative to methyl bromide as a broad spectrum insect fumigant in post-harvest commodity storage and food processing facilities. The need for such alternatives became more pressing as the U.S., a signatory of the Montreal Protocol, gradually reduced the amount of methyl bromide […]

(Beyond Pesticides, April 26, 2012) Beyond Pesticides joins over 30 co-sponsors for the 10th annual National Healthy Schools Day in urging Federal and State governments to step up to improve the environmental health of schools nationwide. Though a growing number of states are beginning to address risks to children in schools, more work must be done to protect children, faculty and staff from unnecessary exposure to harmful chemicals, toxic pesticides and allergens. According to the Healthy Schools Network, the organization that coordinates National Healthy Schools Day, more than two thirds of the nearly 100,000 public school buildings in the country have at least one dire infrastructure problem, however these schools are virtually unregulated by any agency for indoor environmental health and safety standards. Research shows direct links between a school’s poor indoor environment and higher rates of asthma and other respiratory ailments. Other studies show that improving indoor air quality has measurable impacts on student and teacher health and productivity. Children are especially vulnerable to negative effects of toxic pesticide and chemical exposure as they take in more toxins relative to their body weight than adults and have developing organ systems that are less able to detox. In a statement […]

(Beyond Pesticides, April 18, 2012) In the face of widespread pesticide contamination of U.S. waterways and the lack of drinking water standards for hundreds of pesticides, the U.S. Environmental Protection Agency (EPA) has announced new health and environmental benchmarks for acute pesticide effects, postponing action on chronic effects to an unspecified future date. While a step forward in identifying hazards associated with pesticide use and exposure, benchmarks have been notoriously limited in fully assessing risks because of ongoing deficiencies in analyzing the complexities associated with chemical exposure, specifically a failure to evaluate the effects of chemical mixtures, synergistic effects, and health effects associated with consistent low-dose exposure. EPA notes in a newly released April 2012 factsheet, “Human Health Benchmarks for Pesticides,” that, “EPA has developed a table of human health benchmarks for approximately 350 pesticides that are currently registered for use on food crops. The benchmarks are for pesticides for which the agency has not previously issued a drinking water health advisory or set an enforceable federal drinking water standard. These benchmarks for pesticides will enable states, water systems and the public to better determine whether the detection of a pesticide in drinking water or source waters for drinking water […]

(Beyond Pesticides, April 5, 2012) Newly published research has documented that widely used herbicides can adversely impact non-target invertebrate organisms and that endangered species face acute risk from such impacts. Researchers found that adult numbers of the Behr’s metalmark butterfly dropped by one-fourth to more than one-third when its larvae were exposed to herbicides applied in the vicinity of the butterfly’s preferred food source, the naked stem buckwheat plant. The results are especially disturbing because the Behr’s metalmark was being studied as a surrogate for the Lange’s metalmark butterfly, which shares the same habitat and feeding preference and whose population has shrunk from 2,300 in 1999 to less than 100 today. As a federally protected endangered species, the Lange’s metalmark could not be included in the experiment. Researchers concluded that inert ingredients in the herbicide formulations or indirect effects on food plant quality may be causing the increased butterfly mortality. The research was conducted at the 55 acre Antioch Dunes National Wildlife Refuge in Contra Costa County, CA, which is the only known habitat for the Lange’s metalmark. Refuge managers noticed that the naked stem buckwheat, which is native to the refuge and supports both species of butterflies, was being […]

(Beyond Pesticides, March 21, 2012) A half-century after California officials discovered that large amounts of the pesticide DDT had been discharged into a San Francisco Bay canal, the chemical is still poisoning fish and posing a threat to human health despite numerous cleanup attempts. After years of limited success with clean-up, the U.S. Environmental Protection Agency (EPA) has launched a three-year plan to pinpoint the cause of continuously high DDT levels and engage the surrounding community in cleanup and education efforts. The former plant and the adjacent canal, called the Lauritzen Channel, an inlet of the greater San Francisco bay, is one of the most polluted places in the nation. DDT levels have not decreased in the channel even after numerous dredging and other mitigation measures. In fact concentrations have increased. By 2011, DDT concentrations exceeded 1994 levels and some fish have DDT levels in their tissues hundreds of times higher than their counterparts in the rest of the San Francisco Bay. EPA said earlier this month it is launching a three-year plan to help unravel the mystery of why cleanup attempts are failing, and will work with the city to increase awareness among anglers who rely on bay fish […]
