(Beyond Pesticides, September 25, 2012) According to a report from New York City’s Department of Health, Roundup, Monsanto’s most popular and widely used product is also the most frequently applied herbicide in the city. This has occurred in violation of the spirit and intent of the 2005-passed the Pesticide Useage Law (Local Law 37), which put New York City on track to eliminate dependency on hazardous pesticides, and submit a city integrated pest management (IPM) plan to the mayor every January. The report, Pesticide Use by New York City Agencies in 2011, indicates that over 500 gallons of Roundup in various formulations was applied to city ground in the year 2011. While the city is required to report on the total amount and number of herbicide applications, according to an article from Mother Jones, information on the location of these applications is harder to come by. “Parks also declined my request for a sample of the warning sign or safety protocols that it posts around areas where Roundup is sprayed, though signs from previous years noted that Roundup applications, at sites like Central Park’s Turtle Pond and Metropolitan Museum grounds, were done at 4 a.m. Parks didn’t answer my question […]

(Beyond Pesticides, September 24, 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 devoted a $499,778 grant towards developing low-cost water decontamination facilities serving less than 10,000 people. Though conventional water treatment facilities remove many contaminants including suspended solids, bacteria, algae, viruses, fungi, and some chemical pollutants they do not remove many pesticide or antibiotic contaminants. Led by Professor Christopher Bellona, PhD of Clarkson University Civil and Environmental Engineering Departments, research into new water treatment technologies will aim at eliminating these antibiotics and pesticides from potable water. There are currently 88 drinking water contaminants and indicators regulated under the National Primary Drinking Water Regulations which are legally enforceable for public water systems. EPA determines whether a contaminant should be regulated based on peer-reviewed science-based research, with a focus on the health impacts due to exposure. They then propose an enforceable standard in the form of a Maximum Contaminant Level (MCL), taking into account the risks of exposure and availability of technologies to remediate the contaminant. EPA has not established drinking water standards for all the pesticides found in water. Of […]

(Beyond Pesticides, September 21, 2012) A new French study reports that rats fed a diet of Roundup-tolerant genetically modified (GM) corn had an increased risk of developing tumors, suffering organ damage and dying prematurely. The study is the first animal feeding trial studying the lifetime effects of exposure to Roundup tolerant GM corn and has prompted the European Food Safety Authority to look into the study’s results. However, it is also being criticized by some other scientists who said the methodology was flawed and that other research had not found similar problems. The study, “Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize,” which is being published in the peer-reviewed journal Food and Chemical Toxicology, was led by Gilles-Eric SĂ©ralini, PhD, at the University of Caen in France. The study followed 200 rats for two years, the life-span of the rat, but far longer than the typical 90-day feeding studies used in regulatory assessments and subsequent approval of GM crops. The rats were fed different amounts of NK603 corn developed by Monsanto to be resistant to the herbicide Roundup. In some cases, the corn had been sprayed in the field with Roundup. Other rats were given […]

(Beyond Pesticides, September 20, 2012) Raising questions about the adequacy of pesticide regulation, historically and ongoing, Consumer Reports published a new study yesterday that finds “worrisome” levels of inorganic arsenic in rice products. Arsenic is a known human carcinogen. This new report follows its earlier one that finds high levels of arsenic in apple and grape juice. The report finds elevated arsenic levels across organic and conventional products, raising serious questions about widespread environmental and soil contamination from past and continuing arsenical pesticide use. Although organic arsenic occurs naturally in the environment, it is synthetic inorganic arsenic that poses the biggest health hazards to humans and animals. So, humans are exposed to two kinds of the carcinogen in air, water, soil, and food sources. But unlike organic arsenic, which is found naturally in the environment, inorganic arsenic is present in our food as a result of pesticide application and animal feed. Arsenic is added to chicken feed as a supplement to control intestinal parasites and promote growth. It is consequently transferred into the meat of the animals and turns up in chicken manure. Arsenic is also widely used in the treatment of utility poles and in the arsenical herbicide MSMA […]

(Beyond Pesticides, September 19, 2012) The environmental news magazine Earth Focus has launched a new video through Link TV that examines the threat of colony collapse disorder (CCD), and the roll that our regulatory systems and industry plays in the loss of honey bees. The video, Killing Bees: Are Government and Industry Responsible?, features interviews by Beyond Pesticides’ Executive Director Jay Feldman, beekeepers Tom Theobald and David Hackenberg, as well as other experts. Honey bees, the essential pollinators of many of our major crops have been dying of in massive numbers since 2006. This threatens the US agricultural system and the one in twelve American jobs that depends on it. There is growing evidence that a new class of pesticides -nerve toxicants called neonicotinoids- used on most U.S. crops, including almost all corn, may be toxic to bees. The U.S. Environmental Protection Agency allowed neonicotinoids on the market without adequate tests to determine their toxicity to bees. Environmentalists want neonicotinoids banned until needed safety tests are done. While the U.S. government is slow to act and neonicotinoid sales reap billions for the chemical industry, bees continue to die. The video is available to stream or download on Link TV’s website, […]

(Beyond Pesticides, September 18, 2012) Take Action! On September 25, EPA will close its public comment period for the petition requesting the agency to suspend the bee-killing pesticide clothianidin. The U.S Environmental Protection Agency (EPA) has failed to recognize that pollinators face unique hazards from clothianidin, a neonicotinoid pesticide which is linked to disruptions in bee mobility, navigation, and feeding behavior. So far thousands of concerned beekeepers, gardeners, hobbyists and folks like you have told EPA to suspend clothianidin and protect pollinators now! Without your support, clothianidin’s effects on honey bees will continue to put beekeepers, rural economies, and our food system at risk. With one in three bites of food reliant on honey bee pollination, it’s imperative that we act now! Tell EPA to suspend the use of the bee-killer clothianidin and protect pollinators. See sample comments here. If you are having trouble submitting to the docket, click here. Background Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations around the world beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year—but some are losing many […]

(Beyond Pesticides, September 17, 2012) Citizens in rural Oregon are concerned for their health after discovering that several major timber companies —Weyerhaeuser, Roseburg Resources, Stimson Lumber, Seneca Jones and others— have been spraying millions of pounds of herbicides on their private forestland since the 1970s. The pesticides were aerially sprayed after the area had been clear-cut of Douglas fir. This process of clear-cutting and aerial spraying for lumber production is ubiquitous on private forest land in Oregon’s $13 billion timber industry. In practice, pesticides are sprayed twice a year, usually in the fall and spring, and the spraying can last for several hours. It is unclear how many residents have been affected by the spraying, though a rough estimate based on U.S. Census data shows about 100,000 residents live near these privately owned forests. Many of these herbicides are turning up in very concerning places. Over the past year, forty one residents, including several children, have submitted their urine to be tested for pesticides, and every sample has tested positive for the chemicals 2,4-D, and atrazine. The presence of atrazine is particularly concerning because it is very mobile in the environment, and should be able to pass through the body […]

(Beyond Pesticides, September 14, 2012) The State of Massachusetts has been unable to produce the records backing up its claim that the biggest aerial spraying of pesticides in Commonwealth history this July significantly reduced mosquito-borne disease risks, according to Public Employees for Environmental Responsibility (PEER). Further, the state has no proof aerial spraying is an effective safeguard against Eastern Equine Encephalitis (EEE). In a July 31 press release, the Massachusetts Department of Public Health (DPH) announced that “aerial spraying the weekend of July 20-22 reduced the mosquito population by approximately 60 percent within the 21-community spray zone in Southeastern Massachusetts.” DPH Commissioner John Auerbach was quoted as crediting aerial spraying for causing “a significant reduction in the volume of mosquitoes.” Immediately following that release, New England PEER Director Kyla Bennett submitted a public records request for the materials supporting these claims. More than a month later, DPH has still been unable to produce any records on which it based its press release. The matter is on appeal before the Secretary of State, the last administrative hurdle PEER needs to jump over in order to sue DPH to force the production of records. PEER points out that agencies conducting aerial spraying […]

(Beyond Pesticides, September 13, 2012) Are you concerned about industry’s attacks on organic? Do you want to make sure that organic meets your expectations for safety and environmental protection? Do you care about the health of those who grow and harvest the food you eat? Do you want to keep hazardous synthetic substances out of organic food production and processing? Do you want to ensure that all ingredients, including “inert ingredients,” are reviewed? And that your concerns are heard by regulators through an open process with maximum public input? If so, then take a few minutes to let the National Organic Standards Board (NOSB) and USDA know what you think. Let it be your voice rather than your silence that influences the future of organic as it grows. Submit your comments by September 24, 2012. Keep Hazardous Synthetics Out of Organic Your voice is needed to ensure that the NOSB keeps out of organics synthetics that do not meet the core principles and values of organic because they are: (i) hazardous to the environment or people, (ii) incompatible with organic principles and systems, and (iii) not essential and therefore not needed to produce organic food. These core principles apply across […]

(Beyond Pesticides, September 12, 2012) Expectant mothers exposed to the pesticide additive piperonyl butoxide (PBO), widely used in synthetic prethroid insecticides and those ending in “thrin” (popular in mosquito spray programs), during pregnancy pass to their children a heightened risk of noninfectious cough at ages 5 and 6, according to researchers at the Columbia Center for Children’s Environmental Health (CCCEH). These findings support the premise that children’s respiratory system is susceptible to damage from toxic exposures during the prenatal period. Researchers outfitted 224 expectant mothers with air monitors during their third trimester of pregnancy and measured the levels of PBO and permethrin in the air around them. Then, once the children were 5 and 6, the same two chemicals were measured from air samples collected inside their home. Results showed that children exposed to PBO in the womb were at increased odds of reporting cough unrelated to cold or flu. Researchers found no correlation between prenatal or childhood exposure to permethrin, however they pointed out that this may be because PBO is easier to measure in air samples than permethrin. Coauthor of the study, “Prenatal exposure to pesticide ingredient piperonyl butoxide and childhood cough in an urban cohort,” Dr. Rachel […]

(Beyond Pesticides, September 11, 2012) Lawn company giant, Scotts Miracle-Gro Co., pleaded guilty to numerous charges of misleading consumers with unapproved labels and falsifying insecticide registrations, including using toxic chemicals in wild bird food. Scotts was ordered to pay $12.5 million in criminal fines, the largest penalty ever set under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Scotts admitted to using Storcide II and Actellic 5E to prevent insects from damaging the bird food in storage, even though it knew both chemicals were toxic to birds, fish, and other wildlife. In 2008, Scotts Miracle-Gro ceased sales of the tainted birdseed but not before 70 million units of the pesticide-tainted food was sold. The sentence imposed in federal court in Columbus, Ohio, includes a $4 million criminal fine, the Justice Department said. Separately, the company agreed to pay more than $6 million in civil penalties to the U.S. Environmental Protection Agency (EPA) and contribute $500,000 to organizations to protect bird habitats and restore and protect 300 acres of land to prevent runoff of pesticides into waterways —valued at $2 million. EPA has identified more than 100 products produced or sold by Scotts Miracle-Gro that violated the federal pesticide laws over […]

(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 7, 2012) Yesterday, Beyond Pesticides joined with the Center for Food Safety and the Sierra Club, along with beekeepers from around the country, to file a 60-Day Notice letter with the Environmental Protection Agency (EPA) announcing the intent to jointly sue the agency for Endangered Species Act (ESA) violations. The potential lawsuit highlights EPA’s continuing failure to ensure, through consultation with the U.S. Fish and Wildlife Service, that its numerous product approvals for the neonicotinoid insecticides clothianidin and thiamethoxam are not likely to jeopardize any federally-listed threatened or endangered species. “EPA has failed to uphold the clear standards of the Endangered Species Act,” said Peter Jenkins, attorney at the Center for Food Safety. “By continuing to ignore the growing number of reports and studies demonstrating the risks of neonicotinoids to honey bees and a large number of already threatened and endangered species, the EPA is exposing these already compromised populations to potentially irreversible harm.” The Notice of Intent to Sue follows a legal petition previously filed by several environmental organizations and more than two dozen beekeepers requesting that EPA immediately suspend use of the chemical clothianidin that poses fatal harm to pollinators. While refusing to issue an […]

(Beyond Pesticides, September 6, 2012) A review of the scientific literature on the health benefits of organic food versus its chemical-intensive counterpart by Stanford University researchers finds that there is a lack of strong evidence that organic foods contain more nutrients than conventional foods; however, the study finds that consumption of organic foods reduces exposure to pesticide residues and antibiotic-resistant bacteria. The review sparked headlines nationwide questioning the value of purchasing expensive organic food, despite its findings that consumers are exposed to higher levels of pesticides from conventionally grown food. In reaching its conclusions, the study authors chose to discount pesticide hazards by citing the lack of clinical findings and ignoring epidemiologic data on the effects of pesticide exposure. The review, in looking exclusively at the limited clinical data on the benefits of organic food and the hazards of pesticide residues on food, ignored data on the broader benefits of organic practices that protect farmers and farmerworkers, air and water quality, wildlife and biodiversity. The review, Are Organic Foods Safer or Healthier Than Conventional Alternatives?: A Systematic Review, was published in Annals of Internal Medicine. Researchers looked at 240 studies from around the world comparing nutritional value and levels of […]

(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, September 4, 2012) After considering comments from growers and other stakeholders, including over 2,000 emails generated from Beyond Pesticides’ supporters on the recent proposal to reverse a decision to end the use of the organophosphate insecticide azinphos-methyl (AZM), the U.S. Environmental Protection Agency (EPA) has once again come to the conclusion that the chemical presents health risks to workers and can cause negative ecological impacts, while effective alternatives to this insecticide are available to growers. The agency has decided to maintain the initial September 30, 2012 date for cancellation of the remaining uses of AZM, on apples, blueberries, sweet and tart cherries, parsley, and pears. Though this represents a victory for farmworkers and health and environmental advocates, EPA has decided to allow growers to use only existing stocks of AZM in their possession for another year, through September 30, 2013, citing unusually bad weather conditions throughout 2012. All the required mitigation measures now reflected on AZM labeling will remain in effect during this use. Distribution or sale of AZM after September 30, 2012 remains prohibited. Due to industry pressure, the agency initially announced that it was conducting a new risk-benefit analysis (analysis of the impacts of cancellation) and […]

(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 29, 2012) Months after a highly publicized report concluded farming is responsible for underground water contamination in Central Valley, California, the state is poised to approve new groundwater rules to monitor underground water and control discharges of contaminants, such as fertilizers and pesticides. The new regulations, which may involve drilling monitoring wells and testing water, is receiving fierce opposition from industry and farmers who object to paying for monitoring. The new rules that are scheduled for approval early next year will affect about 3,000 farms in Fresno, Tulare, Kings and Kern counties, covering more than 1.6 million acres of farmland. More than 400 farmers and agriculture industry leaders packed an informational meeting held by the Central Valley Regional Water Quality Control Board last week to air their concerns over a plan to protect the region’s groundwater from contamination. The seven-member board heard a day-long presentation by staff members on a draft of the rules to monitor groundwater and control discharges of contaminants such as fertilizers and pesticides. For farmers, that could involve drilling monitoring wells, testing water, hiring consultants and completing paperwork. Staff for the Central Valley Regional Quality Control Board last month based cost estimates on […]

(Beyond Pesticides, August 28, 2012) New research reveals that bats may be at greater risk from pesticide exposure than previously suspected. When foraging at dusk, bats can be exposed to agricultural chemicals by eating insects recently sprayed with pesticides. A study from the University of Koblenz-Landau in Germany reveals that bats, due to their long life span and tendency to only have one offspring at a time, are particularly sensitive to reproductive effects from pesticides. The study, “Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard,” published in Environmental Toxicology and Chemistry, details the health effects of bats foraging on insects in an apple orchard after it was sprayed with the insecticides fenoxycarb and chlorpyrifos. After field applications of the pesticides, scientists measured the remaining chemical residues on flies, moths and spiders for two weeks. The highest residues were recorded on leaf dwelling insects and spiders, while lower contamination was found for flying insects. Based on this data scientists calculated exposure scenarios for different bat species, each with different feeding habits, and found that those which fed off insects from the leaves of fruit trees to be most affected. Researchers indicated that current […]

(Beyond Pesticides, August 27, 2012) A report published recently in the journal Weed Science has found that a population of the common weed waterhemp in Nebraska is resistant to the herbicide 2,4-D. The news comes as the U.S. Department of Agriculture (USDA) considers approving several new crops that have been genetically engineered (GE) for resistance to the herbicide. The report presents the latest in a long line of evidence that crops engineered for herbicide resistance are only pushing the problems of weed management further down the road. Researchers from the University of Nebraska found that half of the waterhemp samples they collected from a Nebraska field, after having been treated regularly for 10 years with 2,4-D,were no longer susceptible to applications of the herbicide. The experiments performed are described by Reuters: “After 10 years of treatment with 2,4-D, waterhemp was no longer effectively controlled in a Nebraska native-grass seed production field, the report said. The highest doses of 2,4-D that were used in an on-site field study were insufficient to control 50 percent of the waterhemp population. Researchers gathered waterhemp seeds from this field and performed greenhouse testing against a susceptible waterhemp variety. Twenty-eight days after treatment with the herbicide, […]

(Beyond Pesticides, August 24, 2012) U.S. Representative Edward Markey, (D-MA) has sent a letter to the U.S. Environmental Protection Agency (EPA) urging it to investigate a possible link between the use of common pesticides and reductions in honey bee populations. The letter comes as EPA is accepting public comments on a legal petition filed by beekeepers and environmental groups seeking to suspend the use of the neonicotinoid pesticide clothianidin, which has been linked to serious pollinator health concerns. In his letter to the EPA, Rep. Markey asks the agency to respond to questions, including: ӢHas the EPA investigated the impacts of the class of pesticides on honey bees and other pollinators? ӢWhat steps has EPA taken, and what more can the agency do, to limit or restrict the use of these pesticides and reduce the impact on bee populations? ӢWhat steps is the EPA taking to ensure there is sufficient scientific evidence to make informed decisions about the impacts of neonicotinoids on bees and other pollinators? Bee pollination contributes an estimated $15 billion to the agricultural economy. Yet, recent research has found that certain members of a group of related pesticides, known as neonicotinoids, may be jeopardizing bee populations and […]

(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 […]
