(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: ”¢Has the EPA investigated the impacts of the class of pesticides on honey bees and other pollinators? ”¢What 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? ”¢What 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 22, 2012) The Oregon Court of Appeals has ordered a temporary halt to the state’s plan to allow genetically engineered (GE) canola to be planted in parts of the Willamette Valley, Oregon. The order is in effect until the court rules on a lawsuit filed by opponents of GE canola planting who say it threatens the state’s $32 million specialty seed industry. The lawsuit and court order are in response to new rules, not subject to required public comment, that would allow for the planting of GE canola in areas previously deemed off-limits. The lawsuit seeking to enjoin the Oregon Department of Agriculture (ODA) from opening to GE canola planting previously protected zones was filed last week in the Oregon Court of Appeals. ODA removed a 2009 rule that banned the planting of all canola on more than 3 million acres in Oregon’s Willamette Valley to protect specialty vegetable seed producers who feared contamination by the plant, which cross-pollinates easily. ODA said it would require GE canola and specialty seed producers to report where and what they intend to grow on 1.7 million acres in the restricted zone, all without a public comment period or hearing. GE […]

(Beyond Pesticides, August 17, 2012) Part of an increasing trend, health care and cosmetics giant Johnson and Johnson has announced that it will soon begin phasing out a number of potentially dangerous chemicals from its personal care brands, including the antibacterial triclosan. Beyond Pesticides and other groups, which have petitioned the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) to remove triclosan from a vast array of consumer products, have urged companies like Johnson and Johnson to take action on the pesticide in the face of inadequate regulation to protect human health and the environment. Along with other chemicals such as formaldehyde and 1,4 dioxane, the company cites consumer concern over the safety of triclosan as among its reasons for the alteration in its products. While the company downplayed any need for concern over the safety of triclosan, it also hinted that it was uncomfortable with growing body of science linking triclosan to a number of health concerns. The phase out is scheduled to be complete by the end of 2015. On a website the company developed specifically regarding the chemical phase out, it stated, in part, “In recent years, some questions have been raised […]

(Beyond Pesticides, August 16, 2012) The antibacterial chemical triclosan, found in popular personal care products such as Colgate ® Total toothpaste and Dial ® Liquid Hand Soap, hinders muscle contractions at a cellular level, slows swimming in fish, and reduces muscular strength in mice, according to scientists at the University of California (UC) Davis, and the University of Colorado. UC Davis’s press release explains that the chemical’s effects are so striking that the study “provides strong evidence that triclosan could have effects on animal and human health at current levels of exposure.” The study, “Triclosan impairs excitation—contraction coupling and Ca2+ dynamics in striated muscle,” published in the Proceedings of the National Academy of Sciences, enlarges a growing body of work linking triclosan to human and environmental health issues. In “test tube” experiments, triclosan impairs the ability of isolated heart muscle cells and skeletal muscle fibers to contract. Specifically, researchers evaluated the effects of triclosan on molecular channels in muscle cells that control the flow of calcium ions, creating muscle contractions. Normally, electrical stimulation (“excitation”) of isolated muscle fibers under experimental conditions evokes a muscle contraction, a phenomenon known as “excitation-contraction coupling” (ECC), the fundamental basis of any muscle movement, including […]

(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 14, 2012) Officials have recently discovered that the Northhampton School district in Massachusetts has been applying an herbicide on the school grounds that is not listed on any of the schools’ integrated pest management (IPM) plans. The herbicide Lesco (active ingredient glyphosate) has been applied up to five times a year at a single school, but typically areas were treated once a year at each school. When questioned, Northampton’s director of custodial services, Michael Diemand, said that since the product, Lesco Prosecutor, can be bought by anyone at stores, it did not need to be on the plans; however this is not what the law states. Under a 2000 state Act Protecting Children and Families from Harmful Pesticides, schools and child care centers are required to submit plans detailing the pest problem that exists at their facilities, the pesticides that they plan to apply, and who will apply the pesticides — even if they are not planning to use pesticides at the current time. The law also requires them to notify parents and employees at least two days before any pesticides are applied at these facilities. Pesticide use is prohibited when children present. Outdoor, pesticides that are […]

(Beyond Pesticides, August 13, 2012) Until last Friday, Willamette Valley’s organic farmers and seed producers were protected from the planting and cross-pollination of their crops by GE canola. However, new rules, fast-tracked without public comment by the Oregon Department of Agriculture (ODA) (announced August 3rd and effective only a week later), now allow for the planting of GE canola in areas previously deemed off-limits. ODA Director Katy Coba states in the department’s press release, “Since canola has been deregulated by USDA, ODA does not differentiate between conventional and GM canola or treat them differently.” Given that 93% of U.S planted canola crops are genetically modified, this move represents a large threat to the integrity of Oregon’s internationally recognized organic seed industry. The new rules are temporary for 180 days, but ODA plans to propose and implement permanent rules before the temporary ones expire. The department will begin accepting public input once the permanent rules are proposed, but by then the canola will already be in the ground. ODA’s decision is a dramatic shift from its previous policy on canola planting in the valley. The previous regulation, ORS 603-052-0880(2) stated, “Production of rapeseed for oil or seed is incompatible with production […]

(Beyond Pesticides, August 10, 2012) A new study is the first to find a difference between how boys and girls respond to prenatal exposure to the insecticide chlorpyrifos. Researchers at the Columbia Center for Children’s Environmental Health (CCCEH) at the Mailman School of Public Health found that, at age 7, boys had greater difficulty with working memory, a key component of IQ, than girls with similar exposures. On the plus side, having nurturing parents improved working memory, especially in boys, although it did not lessen the negative cognitive effects of exposure to the chemical. Results are published online in the journal Neurotoxicology and Teratology. In 2011, research led by Virginia Rauh, ScD, Co-Deputy Director of CCCEH, established a connection between prenatal exposure to chlorpyrifos and deficits in working memory and IQ at age 7. Earlier this year, a follow-up study showed evidence in MRI scans that even low to moderate levels of exposure during pregnancy may lead to long-term, potentially irreversible changes in the brain. The latest study, led by Megan Horton, PhD, explored the impact of sex differences and the home environment on these health outcomes. Dr. Horton and colleagues looked at a subset of 335 mother-child pairs enrolled […]

(Beyond Pesticides, August 8, 2012) Residents of a large condominium in New Jersey have won their fight against the use of pesticides on the complex’s lawn. The homeowner’s association agreed with residents’ pleas to alter its treatment of lawns, instituting an integrated pest management (IPM) policy to avoid using toxic pesticides.In June, several residents at the Society Hill complex in Bernardsville, New Jersey, went public in challenging their homeowners’ association’s decision to use pesticides for lawn care, saying the chemicals have left their children with skin rashes, have sickened, and even killed family dogs. They took their pleas to the Environmental Commission, the Township Committee, The Bernardsville News and even New Jersey 101.5 FM radio. Officials from the Environmental Commission said they could only encourage, not force, private homeowner associations to use organic lawn treatments. Last week, the residents won their battle when the association decided to enact a new pesticide policy. The policy applies integrated pest management (IPM) that avoids pesticides when possible. The association plans to put IPM in all future maintenance contracts so as to maintain consistency. IPM, as defined by Beyond Pesticides, is a program of prevention, monitoring, and control that offers the opportunity to eliminate […]

(Beyond Pesticides, August 7, 2012) Like it or not, Monsanto’s genetically modified sweet corn will soon be arriving on grocery store shelves of the world’s largest retailer, Wal-Mart Stores, Inc., and will not be labeled as such. Despite an onslaught of consumer pressure, the company confirmed late last week with the Chicago Tribune that it has no objection to selling the new crop of Monsanto’s genetically modified (GE) sweet corn. Other retailers, including the grocery chains Safeway and Kroger, have not responded on the issue, however Whole Foods, Trader Joes and General Mills have all vowed to not carry or use the GE sweet corn. As the country’s largest grocery retailer, Wal-Mart sells $129 billion worth of food a year, giving it unmatched power in shaping the food supply chain. The GE sweet corn is the first consumer product developed by Monsanto that will go straight from the farm to the consumer’s plate, rather than first being processed into animal feed, sugars, oils, fibers and other ingredients found in a wide variety of conventional food. It is engineered to be resistant to Monsanto’s Roundup herbicide, the active ingredient of which is glyphosate. The product is also designed to produce a […]

(Beyond Pesticides, August 3, 2012) Pesticide manufactures don’t want you to know what’s in your food. According to filings released Tuesday through the office of California’s Secretary of State, chemical company lobby groups have so far spent $750,000 in efforts to block the passage of California’s Prop 37, which would require mandatory labeling on genetically engineered (GE) foods. Opponents of the proposition raised over one million dollars this year for the “Coalition Against the Deceptive Food Labeling Scheme.” Members of this coalition include the ”˜big 6’ chemical companies Monsanto, Bayer, Syngenta, Dow, DuPont, and BASF, which have spent $375,000 alone through their exclusive lobbying group Council for Biotechnology Information. Overlapping ”˜big 6’ membership, the Grocery Manufacturer’s Association (GMA), which also includes the corporations Pepsico Inc., The Coca-Cola Company, and Kelloggs, recently stated in a speech at the American Soybean Association that defeating the California initiative is “the single highest-priority of the GMA this year,” according to a story in The Huffington Post. GMA has also spent $375,000 this year lobbying against Prop 37. “The Big Six chemical & seed companies are working diligently to monopolize the food system at the expense of consumers, farmers and smaller seed companies,” said Philip […]

(Beyond Pesticides, August 1, 2012) New research is adding to the evidence that some pesticides and industrial chemicals may increase women’s risk of uterine and ovarian diseases, such as endometriosis. The research supports the decades old theory that hormone-mimicking chemicals impact human reproductive systems. Scientists have long suspected a link between estrogen-mimicking pollutants and gynecological diseases. According to Environmental Health News, research investigating a link between hormone-disrupting chemicals in the environment and gynecological diseases has had mixed results. But a new study, “Persistent Lipophilic Environmental Chemicals and Endometriosis: The ENDO Study,” from researchers at the National Institutes of Health and others, found that two groups of women in the Salt Lake City and San Francisco areas — one group with pelvic pain and the other with no symptoms — were more likely to be diagnosed with endometriosis if they had high blood levels of the estrogen-like pesticide hexachlorocyclohexane (HCH) than women with low levels. HCH, a persistent organic pollutant (POP), and a byproduct of the production of the insecticide lindane (head lice treatments), has been banned as a crop pesticide in the United States but it persists in the environment and remains in some food supplies. Endometriosis is a female […]

(Beyond Pesticides, July 31, 2012) Last week, Richmond, California’s City Council unanimously approved a pesticide reform ordinance targeting the use of toxic chemical pesticides within city boundaries. Barring a public health emergency or immediate threat to city property, the regulation bans city departments from using any pesticide considered a known carcinogen (Toxicity Category I and II) by the U.S Environmental Protection Agency. It also prohibits city workers and contractors from applying pesticide products which contain highly toxic organophosphate and carbamate class chemicals. Moreover, with the implementation of the new ordinance, picnic areas, playgrounds, and riparian areas will be considered “no-spray” zones. In other public areas, the legislation puts a strong emphasis on non-chemical methods of pest prevention and control. It would allow the use of least-toxic pesticides only as a last resort, with the intention to significantly reduce or eliminate the use of and exposure to pesticides. The legislation also requires all city departments involved in pest management to submit an implementation plan and undergo training and education programs on least-toxic pest control. According to Roger Roberts of the Contra Costa Times, when the City Council first considered the ordinance in June, some were skeptical of the proposal. They felt […]

(Beyond Pesticides, July 26, 2012) The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) announced this week that it is formally deregulating a line of sugar beets genetically engineered (GE) to resist applications of the herbicide glyphosate. Developed by chemical and seed giant Monsanto Co., the new sugar beets, referred to as “Roundup Ready” (RR), were found by APHIS to not present a risk of becoming a plant pest risk and that they will and are not likely to cause a significant environmental impact. Environmental and public interest advocates, however, point to the fact that the proliferation of glyphosate-tolerant crops has already led to increased pesticide resistance among weeds, and increased pesticide use. The planting of engineered sugar beets brings with it the risk of genetic drift and cross contamination of pollen into non-GE and organic fields growing sugar beets or other related crops, such as table beets, spinach, swiss chard, and quinoa. APHIS originally deregulated RR sugar beets in 2005. A coalition of environmental groups and organic seed companies, led by the Center for Food Safety, challenged the USDA approval in 2008. It argued that GE sugar beets would contaminate organic and non-GE farmers of […]

(Beyond Pesticides, July 25, 2012) A Texas border study has found that air samples in the homes of pregnant Hispanic women contain multiple household pesticides that could harm fetuses and young children. The first study of its kind conducted by the School of Medicine at The University of Texas Health Science Center San Antonio, finds traces of both household and agricultural pesticides that have been linked to disorders such as autism and attention deficit hyperactivity disorder. The researchers sampled air in 25 households, finding at least five pesticides in 60 percent of the dwellings. Nine other pesticides were identified in less than one-third of the homes. All the women were in the third trimester of pregnancy, when the fetal brain undergoes a growth spurt. Numerous studies have reported birth defects and developmental problems when fetuses and infants are exposed to pesticides, especially exposures that adversely affect mental and motor development during infancy and childhood. This new report is in the summer issue of the Texas Public Health Journal sent to members this week. The study found 92 percent of air samples contained o-phenylphenol, which is used as a fungicide, germicide and household disinfectant, while 80 percent of samples contained chlorpyrifos, […]

(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 17th, 2012) On July 8, The New York Times ran an article indicting the organic food industry and the U.S. Department of Agriculgture (USDA) for their involvement in advancing a number of standards, practices, and decisions allowed under the organic label. The Times piece, “Has ”˜Organic’ Been Oversized?,” written by Stephanie Strom and featuring organic food industry critic and chief executive officer of Eden Foods, Michael Potter, concentrated on the outsized role large corporations have assumed economically through organic market share, and politically through the decisions of the National Organic Standards Board (NOSB). While the article reinforces organic advocates’ ongoing call for public vigilance, there is general agreement that organic offers consumers the safest place to spend their food dollars, the best protection for the environment and those who farm, and the highest degree of public input into the standard setting process. Beyond Pesticides’ Executive Director Jay Feldman, current NOSB member holding an environmentalist seat, wrote a response published in the Times article. Mr. Feldman said, “The article noted the involvement of big agriculture and food companies in establishing organic standards, as well as in several controversial decisions. But that discussion only diverts public attention from the […]

(Beyond Pesticides, July 10, 2012) In a victory for human health and organic farmers, the District Court in Delta, Colorado granted a permanent injunction last week to prohibit a farmer from fogging for moquitoes within 150 feet of his neighbor’s property or allowing the pesticides to drift, considering this to be a form of trespass. The victory is important for organic growers and others who are frequently under threat of pesticide drift from neighboring properties. Judge Charles Greenacre determined that an application of the insecticide, Fyfanon, a form of malathion, had drifted, and thus trespassed, onto the neighboring organic farm of Rosemary Bilchak and her husband, Gordon MacAlpine. In granting the permanent injunction, Judge Greenacre decided that: “Plaintiffs have an interest, shared by the public in general, in not having their property invaded by third persons or things. Plaintiffs also have a specific interest in not having pesticides invade their property because such invasions will delay or negate their efforts to have their property certified for the production of organic crops.” Last year, the Minnesota Court of Appeals ruled that pesticides drifting from one farm to another may constitute trespass, and courts in other states have ruled in favor of […]

(Beyond Pesticides, July 9, 2012) Health officials in Connecticut are telling residents who drink from private wells to test their water for the banned pesticides chlordane and dieldrin, after a study from the town of Stamford, CT found at least one of the toxic chemicals in 195 out of 628 wells tested. Over half of the wells that tested positive for one of the pesticides were found to contain concentrations at levels above what the U.S Environmental Protection Agency (EPA) considers acceptable. Both of these chemicals, discussed at length in Rachael Carson’s seminal book Silent Spring, were widely used throughout the country before their ban in the late 1980s. Since then, these chemicals have revealed themselves to be pervasive in our environment. In 2007, Beyond Pesticides wrote on the discovery of chlordane on the grounds of a New Jersey middle school at levels above EPA limits. In 2009, the U.S Housing and Urban Development (HUD) and EPA conducted a survey that found chlordane in 64% of U.S households sampled. In 2010, we reported on the occurrence of these two historic-use chemicals in what are considered “pristine” National Parks. Unfortunately, if the water contamination residents are finding turns out to be […]

(Beyond Pesticides, July 6, 2012) The agribusiness conglomerate DuPont has received more than 30,000 damage claims arising from its sale of a pesticide that resulted in death and injury to hundreds of thousands of evergreen trees, particularly Norway spruce and white pine. DuPont marketed the pesticide, sold under the trade name Imprelis, based on a conditional registration that the U.S. Environmental Protection Agency (EPA) granted in 2010. Soon after Imprelis became commercially available the next spring, EPA began receiving widespread reports of tree death and injury from landscapers and residential users who had applied the pesticide according to its label conditions. EPA issued an immediate stop sale order for Imprelis on August 11, 2011 after DuPont submitted reports of more than 7,000 reports of tree damage. The New York Times reports that DuPont has set aside $225 million for claims that have already been submitted, and that the payout could ultimately reach $575 million. These figures do not include costs related to a class-action lawsuit filed by thousands of homeowners, landscapers and others, consolidated in federal court in Philadelphia. Some claimants are frustrated by the pace of the claims process and communications from the company. “We’re hearing nothing,” said Janet […]
