(Beyond Pesticides, July 31, 2009) A group of advocates and experts is warning that pesticide pollution from farm fields and households is contributing to the Chesapeake Bay’s decline, and may well be linked to declines in frogs across the region and intersex fish seen in the Potomac River. In a report released yesterday, the group calls on federal, state and local government to accelerate research into what threats pesticide contamination may pose to the bay, and to step up efforts to reduce such toxic pollution. “The thing that alarms us the most are the endocrine disruptors and the findings that have come out about intersex fish and frogs with reproductive problems,” said Robert SanGeorge, director of the Pesticides and the Chesapeake Bay Watershed Project. Endocrine disruptors are chemicals that mimic the natural hormones in humans or animals and can disrupt their growth and reproduction. The project is a partnership between the Maryland Pesticides Network and the Johns Hopkins Center for a Livable Future. The group’s warning and recommendations are the product of a two-year study, in consultation with scientists, public health experts, government officials, watermen, environmentalists, farmers and pest management industries. The report comes as federal and state governments attempt […]

(Beyond Pesticides, July 30, 2009) A new report from the Institute of Medicine (IOM) and sponsored by the U.S. Department of Veterans Affairs finds suggestive but limited evidence that exposure to Agent Orange and other herbicides used during the Vietnam War is associated with an increased chance of developing ischemic heart disease and Parkinson’s disease in Vietnam veterans. The report is the latest in a congressionally mandated series by IOM that every two years reviews the evidence about the health effects of these herbicides and a type of dioxin – TCDD – that contaminated some of the defoliants. A finding of “limited or suggestive evidence of an association” means that the evidence indicates there could be a link between exposure to a chemical and increased risk for a particular health effect, though conflicting results from studies, problems with how the studies were conducted, or other confounding factors limit the certainty of the evidence. Until now, the cumulative evidence had been inadequate to draw conclusions about whether these two conditions may be associated with veterans’ exposures to herbicides or TCDD. Ischemic heart disease – a condition characterized by reduced blood supply to the heart, which can lead to heart attack and […]

(Beyond Pesticides, July 29, 2009) A new study by researchers at the Lombardi Comprehensive Cancer Center at Georgetown University finds a higher level of common household pesticides in the urine of children with acute lymphoblastic leukemia (ALL), a cancer that develops most commonly between three and seven years of age. The findings are published in the August issue of the journal Therapeutic Drug Monitoring. Researchers, in the study entitled, “Pediatric Acute Lymphoblastic Leukemia and Exposure to Pesticides,” caution that these findings, which do not establish a cause-and-effect relationship, suggest an association between pesticide exposure and development of childhood ALL. “In our study, we compared urine samples from children with ALL and their mothers with healthy children and their moms. We found elevated levels of common household pesticides more often in the mother-child pairs affected by cancer,” says the study’s lead investigator, Offie Soldin, Ph.D., an epidemiologist at Lombardi. Dr. Soldin cautions, “We shouldn’t assume that pesticides caused these cancers, but our findings certainly support the need for more robust research in this area.” Previous studies have found that exposures to certain pesticides increases the risk of developing certain cancers and degenerative diseases. The study was conducted between January 2005 and […]

(Beyond Pesticides, July 28, 2009) A new study by researchers at the National Food Institute, Technical University of Denmark shows that exposure to a mixture of pesticides and other chemicals has a synergistic effect on the development of male sex organs. Synergy occurs when the effect of multiple chemicals is greater than the sum of the individual effects. The study, “Synergistic Disruption of External Male Sex Organ Development by a Mixture of Four Antiandrogens,” was published July 15, 2009 in the online edition of Environmental Health Perspectives. The researchers designed their study to determine the consequences of simultaneous exposure to multiple “antiandrogens.” An antiandrogen, or androgen antagonist, is any of a group of hormone receptor antagonist compounds that are capable of preventing or inhibiting the biologic effects of androgens, male sex hormones, on normally responsive tissues in the body. Disrupting the action of androgens during gestation, certain chemicals present in food, consumer products and the environment can induce irreversible malformations of sex organs among male offspring. The team investigated the effects of mixtures of a widely used plasticizer, di(2-ethylhexyl) phthalate (DEHP), used in medical devices such as IV bags and tubing, beauty products, PVC toys, vinyl shower curtains, car seats, […]

(Beyond Pesticides, July 27, 2009) A mother’s exposure to urban air pollutants known as polycyclic aromatic hydrocarbons (PAHs) can adversely affect a child’s intelligence quotient or IQ, according to the new study “Prenatal Airborne Polycyclic Aromatic Hydrocarbon Exposure and Child IQ at Age 5 Years.” PAHs are widespread in urban environments and throughout the world as they have many sources, several of which are related to pesticides, including creosote used for wood preservation, burning pesticide-laden grass seed fields, and exposure to organochlorine pesticides whether banned, yet ubiquitous DDT or the still used insecticide dicofol. Other sources include synthetic turf fields and the burning of coal, diesel, oil and gas, or other organic substances such as tobacco. PAHs have been known to be bioaccumulative, carcinogenic and disrupt the endocrine system. The new study, funded by the National Institute of Environmental Health Sciences (NIEHS), a branch of the National Institutes of Health, the U.S. Environmental Protection Agency and several private foundations, found that children exposed to high levels of PAHs in New York City had full scale and verbal IQ scores that were 4.31 and 4.67 points lower than those of less exposed children. High PAH levels were defined as above the […]

(Beyond Pesticides, July 24, 2009) Whole Foods Market, a leading natural and organic grocery chain, recently announced a commitment to the Non-GMO Project, a non-profit collaboration of manufacturers, retailers, processors, distributors, farmers, seed breeders and consumers, to use the Non-GMO Project’s Product Verification Program (PVP) in connection with Whole Foods Market’s private label products. The 365 Every Day Value and Whole Foods Market brands will be enrolled in the program, with the first products arriving on shelves this Fall. While Federal law requires organic producers to comply with certain non-genetically engineered (GE) requirements identified in the USDA organic standards, there is no standard for labeling them in non-organic products. The PVP is the first system in the U.S.designed to scientifically test whether a product has met a set of defined standards for the presence of GE organisms (also known as GMOs, or genetically modified organisms). “From the moment GMOs were approved for use in the U.S., we recognized the need for transparency, but there was no definitive standard by which to evaluate or label products,” said Margaret Wittenberg, Whole Foods Market global vice president of quality standards. “We searched high and low for years for a way to do this […]

(Beyond Pesticides, July 23, 2009) A new study published in the August 2009 issue of Environmental Toxicology and Chemistry found that insecticides used in highly populated agricultural areas of California’s Central Valley affect amphibians that breed in the Sierra Nevada Mountains to the east. This study adds to the increasing evidence that pesticides impact areas and wildlife species that are miles from sources of pesticide application. Researchers from the Cooperative Wildlife Research Laboratory, Southern Illinois University and U.S. Geological Survey (USGS) examined the chronic toxicity of two of the insecticides most commonly used in the Central Valley- chlorpyrifos and endosulfan, to larval Pacific treefrogs (Pseudacris regilla) and foothill yellow-legged frogs (Rana boylii), the amphibians with declining populations that live and breed in meadows surrounding the Sierra Nevada. The results are discussed in “Toxicity of Two Insecticides to California, USA, Anurans and Its Relevance to Declining Amphibian Populations.” The study used laboratory testing to examine how the insecticides affected the two frogs at environmentally realistic concentrations. During testing, tadpoles were observed at various stages of development to see how the insecticides affected their growth and health. The researchers found that endosulfan was more toxic than chlorpyrifos to both species, and tadpoles […]

(Beyond Pesticides, July 22, 2009) The Oregon Department of Agriculture (ODA) recently released statistics for statewide pesticide use in 2008, while at the same time announcing the suspension of the reporting system, which has only been collecting data since 2007. The Pesticide Use Reporting System (PURS) was suspended until 2013 by House Bill 2999, due to lack of funding. The $800,000 saved will instead be used to fund two investigator positions. Until its reinstatement, officials will be unable to collect data or pursue enforcement related to missing reports from earlier in 2009. The 2008 PURS report documents agricultural and household pesticide use, which totaled almost 20,000 pounds and 572 different active ingredients. The top five active ingredients, by pounds, were all used in agriculture: metam sodium, glyphosate, 1,3-dichloropropene, sulfuric acid, and aliphatic petroleum hydrocarbons. Agriculture totaled 77 percent of all pesticide use, with urban/general indoor and outdoor uses totaling under four percent. The total used dropped by half from 2007, due in part to improved record keeping and a decline in the use of metam sodium, a popular fumigant in potato production. In households, pesticide use may be shifting away from the most toxic products. “In 2007, everyone was just […]

(Beyond Pesticides, July 21, 2009) Last week, Uncommon Ground, an eco-conscious restaurant in Chicago, opened the first certified organic rooftop farm. Receiving certification through Midwest Organic Services Association (MOSA) in October of 2008, the 250 square foot space includes approximately 640 square feet of soil which is used to grow a variety of high-yield crops. The plants are rotated in containers throughout the season and are served to diners in the restaurant below. The fresh produce featured on the menu includes sweet and hot peppers, eggplant, lettuces, heirloom tomatoes, greens, radishes, beets, okra, spinach, fennel, mustard, edamame, beans, shallots, garlic as well as plenty of herbs to keep diners happy. The farm is stocked by plants raised by local organic farmers Jenny Borchardt and Harvest Moon Farm, and by seeds that were purchased from Seed Savers, Johnny’s and Seeds of Change, as well as those that have been cultivated from successful plants. In 2007, the same year that Beyond Pesticides toured the Chicago City Hall Green Roof at our 25th National Pesticide forum Changing Course in a Changing Climate, Uncommon Ground restaurant owners Helen and Michael Cameron decided to find a second home to expand their business, making it as […]

(Beyond Pesticides, July 20, 2009) Public health and environmental advocates have asked the U.S. Environmental Protection Agency (EPA) to deny a request from Dow AgroSciences for a permit allowing it to release large amounts of sulfuryl fluoride, a toxic pesticide whose global warming effects are thousands of times stronger than carbon dioxide, onto farm fields in four states. Dow AgroSciences proposes using sulfuryl fluoride to sterilize soil in farm fields. The permit would allow the release of 32,435 pounds of sulfuryl fluoride on 65 acres of test plots in Florida, Georgia, Texas, and California. Yet, researchers have found that sulfuryl fluoride stays in the atmosphere at least 30-40 years and perhaps as long as 100 years and is about 4,000 times more efficient than carbon dioxide at trapping heat. Because of the aggregate effects of surfuryl fluoride, Beyond Pesticides jonined Fluroide Action Network and Envirornmental Working Group in petitioning the U.S. Environmental Protection Agency (EPA) to cancel the registration of the chemical due to dangerous levels in food and water. “The hazards of using sulfuryl fluoride in agriculture have not been evaluated,” said Brian Hill, Ph.D., a staff scientist at the Pesticide Action Network. Releasing just 10 percent of the […]

(Beyond Pesticides, July 17, 2009) High levels of pyrethroid pesticides in the Sacramento-San Joaquin River Delta, the number one river system on America’s Most Endangered Rivers List of 2009, has been linked to heavy urbanization in the region. Leading a study to understand the collapse of the delta’s ecosystem, University of California-Berkeley toxicologist Donald Weston, Ph.D. found that these pesticides most likely reached the river from urban storm drains, collecting household pesticide disposal and runoff from lawns of 1.4 million residents in the Sacramento region. Five years ago, a study by Dr. Weston and his colleague Michael J. Lydy, Ph.D of Southern Illinois University in Carbondale found that synthetic phyrethroids were collecting in river and creek sediments at levels that are toxic to bottom dwelling fish. Current research holds that there are enough pyrethroids to kill tiny shrimp, which are said to be the first link in the aquatic food chain. Pyrethroids are synthetic versions of pyrethrin, a natural insecticide found in certain species of chrysanthemum. It initially came on the market as a ”˜safer’ alternative to the heavily regulated and highly toxic organophosphates, such as diazinon and chlorypyrifos. Despite the fact that there are plenty of effective pest control […]

(Beyond Pesticides, July 16, 2009) The U.S. Environmental Protection Agency (EPA) has issued a Final Work Plan (FWP) for the registration review of imidacloprid. A neonicotinoid insecticide, imidacloprid is highly toxic to honeybees on an acute exposure basis, and has been implicated in the recent Colony Collapse Disorder (CCD) that has occurred throughout the U.S. Over 12,000 comments were received by the agency since December 2008, urging the agency to suspend the use of this controversial chemical. Imidacloprid was first registered in the U.S. in 1994 as an insecticide to control a range of pests on crops, structures, indoor and outdoor residential areas, as well as pet products. While the use of imidacloprid has been gaining in popularity, its health and environmental effects have not been adequately studied. EPA, with its registration review program, pursuant to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) section 3(g), must review each registered pesticide every 15 years to determine whether it continues to meet the FIFRA standard for registration. The public docket for imidacloprid was opened in December 2008 and has since received over 12,000 comments, including those submitted by Beyond Pesticides, NRDC, the National Honey Bee Advisory Board (NHBAB) and Sierra Club, […]

On July 14, 2009, Beyond Pesticides and Food and Water Watch submitted an amended petition to the United States Food and Drug Administration (FDA) requiring that the agency ban the use of the controversial pesticide triclosan for non-medical applications on the basis that those uses violate the Federal Food, Drug and Cosmetics Act. Strong scientific evidence suggests that pervasive use of triclosan poses imminent threats to human health and the environment. “Numerous scientific studies and reports clearly indicate that in addition to its human health and environmental dangers, triclosan is not effective for many of its intended benefits and may actually be doing consumers more harm than good,” said Wenonah Hauter, executive director of Food & Water Watch. “Even worse, is that current regulations on triclosan haven’t been updated since 1994 and much of the science used by the FDA to regulate the pesticide dates back to the late 1970s and early 1980s. The agency’s inconsideration of new scientific research on triclosan represents an egregious failure to properly protect the public against this dangerous pesticide.” Regulated by both the FDA and the United States Environmental Protection Agency (EPA), triclosan is commonly found in hand soaps, toothpastes, deodorants, laundry detergents, fabric […]

(Beyond Pesticides, July 14, 2009) With language to exclude farmworkers from coverage, on July 10, 2009, Senator Kay Hagan (D-NC) introduced Senate Amendment 200 to the Affordable Health Choices Act, the health care reform bill being considered in the Senate Committee on Health, Education, Labor and Pensions (HELP). According to the advocacy group Farmworker Justice, her amendment would exclude from the definition of “employees” any “temporary or seasonal agricultural workers ”¦ for the purposes of determining the size of an employer.” Agricultural employers of seasonal farmworkers would not be required to participate in the system because they would be considered to be too small. Seasonal farmworkers would be denied health care coverage. “There can be no good explanation for why Senator Hagan thinks it would be a good idea to exclude seasonal farmworkers from access to affordable health care coverage, other than that she is pandering to agricultural employers and upholding the long tradition of excluding some of America’s lowest paid and hardest working employees from the benefits that other workers receive,” said attorney Kate Woomer-Deters of the North Carolina Justice Center. Farmworkers in the U.S. earn an average of $12,500 to $15,000 per year. They work in some of […]

(Beyond Pesticides, July 13, 2009) With the stroke of a pen, Governor Arnold Schwarzenegger could bow to industry interests and force the California Department of Pesticide Regulation to register a new fumigant pesticide, methyl iodide. Highly toxic, and not approved for use in California, this chemical has been given a comprehensive review by the state’s own Department of Pesticide Regulation (DPR) and found to be one of the riskiest pesticides in existence. Scientists familiar with methyl iodide are asking Mr. Schwarzenegger to let science, rather than political pressure, guide this decision. “Methyl iodide is so toxic that scientists working with it in the laboratory take extreme precautions when handling it, using a ventilation hood, gloves, and special equipment for transferring it so it does not escape to the air,” notes Susan Kegley, Ph.D., a chemist and consulting scientist for Pesticide Action Network North America. “This degree of protection is not possible in an agricultural setting where the pesticide would be applied at rates of 175 pounds per acre in the open air. Buffer zones of 400 feet (a distance most growers would say is unworkable) for a 40-acre fumigation would still result in a dose of methyl iodide to neighbors […]

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

(Beyond Pesticides, July 9, 2009) Recent news that Dean Foods intends to launch a “natural milk” brand has organic consumers and retailers concerned. Horizon, a strictly organic brand up until now, is poised to sell products that are not certified organic. This new product category will offer conscientious consumers what appears to be a cheap alternative to organic, when in fact it is nothing more than a conventional product in a fancy package. Despite recent news that the organics industry as a whole continues to grow in this economy, encouraging consumers to steer away from the certified organic label with misleading product claims purports to devastate the organic movement and organic family farm. “This move by Dean Foods comes at a time when organic dairy farmers around the country are in financial crisis due to a glut of milk,” says Mark A. Kastel, Senior Farm Policy Analyst at The Cornucopia Institute. “Responsible participants in this industry are using their marketing strength to ramp up organic demand. Dean has instead chosen to profiteer at the expense of the hard-working family farmers who have built this industry.” The USDA Organic Label is intended to show consumers that the product adheres to uniform […]

(Beyond Pesticides, July 8, 2009) Pesticide campaigner Georgina Downs’ high court victory last November, when a court ruled that there was “solid evidence” that rural residents had suffered harm from crop spraying with toxic chemicals, was overturned yesterday by the Court of Appeal. Three judges on the Court of Appeal concluded that the government has complied with its obligations under European law and that it followed guidance that gave priority to human health. The agriculture industry hailed the ruling as a victory for “common sense.” Georgina Downs, who lives on the edge of farmland, launched a campaign in 2001 against the Department of the Environment, Food and Rural Affairs (DEFRA), documenting and collected evidence from other rural residents reporting health problems including cancer, Parkinson’s disease and asthma believed to be linked to crop spraying. Last November, Justice Collins said there was “a very strong case for a buffer zone” between spraying and human habitation. He ruled that the government had failed to comply with a European directive to protect people from the possible harmful effects of exposure to toxic chemicals. DEFRA challenged the ruling and yesterday the Court of Appeal overturned Justice Collins’ decision. The three judges on the Court […]

(Beyond Pesticides, July 7, 2009) Utah State University scientists are researching a fungus that eats Mormon crickets (Anabrus simplex) alive by depositing spores inside them that multiply and eventually break through their exoskeletons, according to a July 1, 2009 article in the Herald Journal. While the fungus is already providing an organic method of controlling crickets and grasshoppers in Australia, Africa and South America, exotic species laws prevent people in the U.S. from importing it. Now the USU team is searching near the U.S. border with Mexico, where they believe they will find it. The research team, led by USU insect pathologist Donald Roberts, PhD, is analyzing 10,000 soil samples gathered by the U.S. Department of Agriculture (USDA) in 17 states. After isolating the various fungi, each is grown in the lab and tested individually on Mormon crickets. Because the Mormon cricket is actually a katydid and more closely related to grasshoppers than crickets, it could be used as an organic control on other unwanted grasshopper species. The research team warns that while they believe the fungus will not harm fish or mammals, it could harm non-target insects. They also question its effectiveness during huge swarms and admit the fungus’s […]

(Beyond Pesticides, July 6, 2009) Last week, the U.S. Environmental Protection Agency (EPA) proposed to formally evaluate the harmful effects of 74 pesticides on 11 endangered and threatened species in the San Francisco Bay Area over the next five years, and to impose interim restrictions on use of these pesticides in and adjacent to endangered species habitats. The proposal stems from a settlement agreement with the Center for Biological Diversity, which sued EPA in 2007 for violating the Endangered Species Act by registering and allowing the use of toxic pesticides in Bay Area endangered species habitats without determining whether the chemicals jeopardize those species’ existence. “Tens of millions of pounds of toxic and poisonous chemicals, known to be deadly to endangered species and harmful to human health, including proven carcinogens and endocrine disruptors, are applied in the Bay Area each year, and many of those find their way through runoff or drift into our soil, creeks and rivers, San Francisco Bay, and sensitive wildlife habitats,” said Jeff Miller, conservation advocate with the Center. “The toxic stew of pesticides in the Bay-Delta has played a major role in the collapse of native fish populations, and pesticides are a leading cause of […]

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

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