(Beyond Pesticides, April 23, 2008) Ontario is moving to reduce exposure to toxic chemicals by banning the sale and cosmetic use of pesticides. Legislation to be introduced today would make Ontario’s pesticide rules among the toughest in North America. It would also replace a variety of municipal by-laws in place across the province.Studies by public health experts are showing growing evidence of the potential health risk of pesticides, particularly for children. The ban would likely take effect next spring. It would not affect pesticides used for farming or forestry. Golf courses would still be able to use pesticides, but must meet certain conditions to minimize environmental impacts. Pesticides would still be allowed for control of mosquitoes and other insects determined to represent a health threat. “Our generation is becoming more and more aware of the potential risks in our environment, not only to our health, but to our children’s health. That’s why we’re taking action on behalf of the next generation of Ontarians, and reducing their exposure to chemicals,” said Premier Dalton McGuinty. “Many municipalities have already shown leadership in banning or restricting cosmetic-use pesticides. We’re extending that protection to all families wherever they live,” said Environment Minister John Gerretsen. […]

(Beyond Pesticides, April 15, 2008) Thanks to the organizing efforts of the local Environmental Action Task Force, the town of Greenwich, CT has banned the use of pesticides on all of its athletic fields. The first application of the year, which was set for April 14, 2008, was cancelled after the Board of Selectmen passed a resolution mandating the ban. “It’s very exciting,” Selectman Lin Lavery told Greenwich Time newspaper. “It shows the town’s commitment to being a leader on environmental issues.” According to the newspaper, the Environmental Action Task Force proposed the resolution in response to a state law banning the use of pesticides on all elementary and middle school grounds, that goes into effect next year. But the task force took the mandate a step further, banning pesticides on all town athletic fields and instituting it a year early. It seemed logical to move forward with a ban as quickly as possible once it was determined that these pesticides were toxic and potentially harmful to children, Lavery told Greenwich Time. Pesticides, such as Barricade- containing the active ingredient prodiamine, which is used on town fields, is a possible human carcinogen and suspected endocrine disruptor. Michael Franco, M.D., a […]

(Beyond Pesticides, April 10, 2008) Common frogs that live in suburban areas are more likely than their rural counterparts to develop reproductive abnormalities, according to David Skelly, PhD, professor of ecology at the Yale School of Forestry and Environmental Studies. This phenomenon becomes a serious concern as the frog’s mating season begins, leaving researchers to wonder: will frogs be clear on their role in the annual ritual? Research by Dr. Skelly, soon to be published, focuses on the common green frog, Rana clamitans, within the Connecticut River Valley. A total of 233 frogs were collected from various ponds and landscapes with the river valley and among them 13 percent have abnormalities occurring in their reproductive organs. In urban areas, 18 percent of the collected frogs are intersex, and in suburban areas 21 percent. Frogs collected from agricultural areas have the lowest rate of reproductive problems with just 7 percent classified as intersex. According to Dr. Skelly, the more suburban the land cover, the more likely the abnormalities. “This is the first evidence that I think anyone has provided that agriculture is doing anything but pushing those rates higher,” remarked Dr. Skelly of the intersex phenomena. In an attempt to explain […]

(Beyond Pesticides, April 7, 2008) A coalition of farmworker advocates and environmental groups filed a lawsuit against the Environmental Protection Agency (EPA) to stop the continued use of four deadly organophosphate pesticides. These pesticides were derived from nerve gas developed during World War II. Some of these pesticides have been detected in California’s rural schoolyards and homes, Sequoia National Park, and Monterey Bay. The four organophosphates at issue in the case filed April 4 are methidathion, oxydemeton-methyl, methamidophos, and ethoprop. They are used primarily in California on a wide variety of fruit, vegetable, and nut crops. “These four pesticides put thousands of farmworkers and their families at risk of serious illness every year,” said Patti Goldman, an attorney for Earthjustice, the environmental law firm that represents the coalition. “It is inexcusable for EPA to allow use of pesticides that they know are harming people, especially children.” EPA has documented that children are especially susceptible to poisoning from organophosphates. Exposure can cause dizziness, vomiting, convulsions, numbness in the limbs, loss of intellectual functioning, and death. Some organophosphates also cause hormone disruption, birth defects, and cancer. “Farmworkers, and all people living in and near agricultural regions, especially children, are at great risk […]

(Beyond Pesticides, April 4, 2008) A study called “Long-term persistence of GM oilseed rape in the seedbank,” recently published in the journal Biology Letters, has found a genetically modified (GM) crop to persist in spite of a decade of efforts to remove it from a field. Researchers from Sweden’s Lund University and the Danish Technical University found GM oilseed rape (also known as canola) plants still growing ten years after seeds were planted. According to the study, the result contrasts previous trials: “In general, studies suggest that the majority of seeds disappear from the seedbank within two years.” The oilseed rape volunteer (rogue) plants were discovered by their resistance to the herbicide glufosinate. Researchers wrote, “This finding of volunteers, despite labour intensive control for 10 years [including intensive chemical spraying], supports previous suggestions that voulnteer oilseed rape needs to be carefully managed in order for non-GM crops to be planted after GM crops.” They added, “These results are important in relation to debating and regulating coexistence of GM and non-GM crops.” The study’s findings are consistent with previous research. A larger French study found similar survival of volunteer plants eight years after a GM trial. Swedish researcher Dr. Tina D’Hertefeldt […]

(Beyond Pesticides, April 3, 2008) Wines on sale in the European Union (EU), including wines made by world famous vineyards, contain residues of a number of pesticides, according to a new report by Pesticide Action Network Europe. The organization tested 40 bottles of wine purchased inside the EU from Australia, Austria, Chile, France, Italy, Germany, Portugal and South Africa, six of which were organic wines. Every bottle of conventional wine included in the analysis was found to contain pesticides, with one bottle containing 10 different pesticides. On average each wine sample contained over four pesticides. The analysis revealed 24 different pesticide contaminants, including five classified as being carcinogenic, mutagenic, toxic to the reproductive system or endocrine disrupting. The most widespread pesticide contaminant was pyrimethanil, a possible carcinogen, which was detected in 25 bottles of conventional wine — almost 75% of all conventional samples analyzed. While the majority of wines tested were selected from low cost affordable brands, three of the bottles are world famous Bordeaux wines and more expensive, according to PAN Europe. The discovery of pesticides in samples of wine follows the publication of a report by the French Ministry of Agriculture which identified 15 pesticides as being systematically […]

(Beyond Pesticides, April 2, 2008) A study that analyzed chemical contamination in clothes found that fabrics absorb high concentrations of moth repellents, and retain these concentrations even after prolonged airing. These contaminated fabrics then serve as secondary sources of indoor air pollution once the chemicals are released back into the air. Moth repellents, which contain naphthalene and/or p-dichlorobenzene, as well as camphor, have been recognized as major contributors to indoor air pollution. However, their persistence in the fabrics they are used to protect has been underestimated. The study entitled, “Domestic sampling: Exposure assessment to moth repellent products using ultrasonic extraction and capillary GC-MS,” published in Chemosphere, revealed that once cloths are exposed to moth repellents, whether directly or indirectly, high concentrations of p-dichlorobenzene, naphthalene and camphor are detected even after airing. A regular cotton shirt, for example, placed in a cabinet containing one tablet of moth repellent was found to contain up to 7, 3 and 7.5mg of p-dichlorobenzene, naphthalene and camphor respectively after airing for 1 hour. These concentrations are high when compared with the average exposure to p-dichlorobenzene at about 35 micrograms (μg), and the average indoor exposure from naphthalene at less than 1ppb. While airing did reduce […]

(Beyond Pesticides, March 24, 2008) Scientists at the U.S. Geological Survey (USGS) announced that they have identified ten contaminants, including pesticides, in the Potomac River, which flows through downtown Washington, DC, that could be responsible for the alarming discovery of “intersex fish,” male fish producing eggs. The suspected chemicals include: atrazine, a common herbicide used in agriculture and on lawns that is already linked to sexual abnormalities in frogs; insecticides chlorpyrifos and endosulfan; the herbicide metolachlor; and two chemicals used to add fragrance to perfumes, soaps and other products, tonalide and galaxolide. To collect the samples, USGS scientists suspended a device intended to serve as a facsimile fish in the Potomac River near the Washington, DC’s Blue Plains sewage plant. The device had a plastic-coated tube, which simulated a fish’s permeable skin, and a layer of simulated fat. According to the Washington Post, the tests on this fake fat revealed a range of potentially worrisome pollutants. Most have been found in other streams around the U.S. “The types of things we’re finding are the types of things that are associated with everyday life,” David Alvarez, a U.S. Geological Survey research chemist who analyzed samples from the Potomac told the Washington […]

(Beyond Pesticides, March 20, 2008) A 2000-2005 U.S. Geological Survey (USGS) study, Pesticide Occurrence and Distribution in the Lower Clackamas River Basin, Oregon, 2000-2005, finds a variety of pesticides in river and tributary samples, along with trace-level detections of pesticides in treated drinking-water samples collected from a drinking-water treatment plant that uses the Clackamas River as a raw-water source. While the federal government is quick to point out that detections in drinking water are below existing Environmental Protection Agency (EPA) drinking-water standards and most river samples are below the agency’s aquatic life benchmarks, studies show hazardous endocrine-disrupting and immunosuppressive effects at extremely low levels — far below EPA standards. A total of 63 pesticide compounds were detected in 119 water samples collected during storm and non-storm conditions using low-level detection methods. More pesticides were detected in the tributaries than in the Clackamas River mainstem. One or more of 15 pesticides were detected in nine of 15 samples of drinking water. Environmental and public health advocates are concerned that these results add to a pattern of contamination across the country. USGS data released in 2008, shows widespread pesticide contamination in the Chesapeake Bay watershed, and a 2004 USGS report of nationwide […]

(Beyond Pesticides, March 18, 2008) To kick off National Poison Prevention Week on March 17, the U.S. Environmental Protection Agency (EPA) is urging people to “lock up” their pesticides to protect children —stopping far short of advising the public on non-toxic methods of pest management. According to public health advocates, EPA, as a facilitator and apologist for the unnecessary use of highly toxic pesticides that it registers missed an important opportunity during National Poison Prevention Week to alert families with children about integrated management and organic methods that are effective but not reliant on hazardous methods. “With the wide availability of non-toxic methods and products, there is no reason for people to have poisonous pesticides in their homes and risk their children’s exposure,” said Jay Feldman, executive director of Beyond Pesticides. Despite numerous scientific studies that show children carrying a body burden of pesticides used in homes and elevated rates of childhood cancer in households that use pesticides, given children special vulnerability to pesticides, EPA chose to focus on pesticide poisoning of children associated with accidental ingestion. The agency launched the week with the headline “Play It Safe, Prevent Poisonings, Lock Up Pesticides” and the quote, “The U.S. Environmental Protection […]

(Beyond Pesticides, March 17, 2008) Not everything that goes down the drain can be removed by water treatment plants, which leaves some alarming contaminants in America’s drinking water. A five-month investigation by the Associated Press (AP) finds trace quantities of pharmaceuticals in the drinking water of 41 million Americans. Scientists fear that ingestion of these tiny amounts of drugs may pose health risks to the public, wildlife and aquatic organisms. The AP investigation surveyed the 50 largest cities in the country and a dozen other major water providers, as well as other small providers in each of the 50 states. A wide range of pharmaceuticals, whether administered to humans or to farm animals, are found in the water of 24 major metropolitan areas, and tests done in the watersheds of 35 major water providers shows 28 testing positive for pharmaceuticals. The levels of pharmaceuticals found in the water are at levels measured in the parts per billion or trillion, far below levels of medical use. The federal government has not set safety limits for drugs in drinking water. In fact, fewer than half of the 62 major water providers could say their water was tested. Water treatment plants are not […]

(Beyond Pesticides, March 13, 2008) Exposure to certain chemicals, including pesticides and nerve agents, explains the high rates of illness in Persian Gulf War Veterans, according to a new study published in the Proceedings of the National Academy of Sciences. Veterans from the 1990-91 conflict have a higher rate of chronic, multi-symptom health problems than either non-deployed personnel or those deployed elsewhere. Symptoms routinely reported by these veterans include fatigue, muscle or joint pain, memory problems, trouble sleeping, rash and breathing problems. Due to the findings, the study author, Beatrice Golomb, M.D., Ph.D., associate professor of medicine at the University of California, San Diego School of Medicine, warns of the potential risk to civilians exposed to pesticides.“Health issues among Gulf War veterans have been a concern for nearly two decades. Now, enough studies have been conducted, and results shared, to be able to say with considerable confidence that there is a link between chemical exposure and chronic, multi-symptom health problems,” said Dr. Golomb. “Furthermore, the same chemicals affecting Gulf War veterans may be involved in similar cases of unexplained, multi-symptom health problems in the general population.”The study synthesized evidence regarding a class of chemicals known as acetylcholinesterase inhibitors (AchEs), including […]

(Beyond Pesticides, March 11, 2008) A Decade of Children’s Health Research: Highlights from EPA’s Science to Achieve Results Program, a ten-year Environmental Protection Agency (EPA) study released March 10, 2008, summarizes important research findings found from $127 million invested in research grants on children’s environmental health in response to an executive order issued in 1997. Executive Order 13045, Protection of Children From Environmental Health Risks and Safety Risks, requires federal agencies to place a high priority on assessing risks to children. EPA, through its Science to Achieve Results (STAR) program, issued more than 60 research grants in response to this order, which in turn, produced more than 1000 scientific journal articles. “Understanding potential environmental health risks to children is important to EPA,” said George Gray, assistant administrator of EPA’s Office of Research and Development. “This research will help us assess and address environmental factors that may affect some of the most vulnerable members of our society.” The report summarizes research from the STAR children’s health program over the past 10 years, highlighting scientific findings in epidemiology, exposure science, genetics, community-based participatory research, interventions, statistics and methods. Some of the major findings of this research include: People metabolize pesticides differently based […]

(Beyond Pesticides, March 10, 2008) Head lice affect an estimated 12 million people in the U.S. each year, and are rapidly becoming resistant to over-the-counter and prescription medications. Researchers at the University of Massachusetts Amherst have found that ivermectin, a compound produced by soil-dwelling bacteria, was 100 percent effective in killing head lice resistant to many standard treatments. Results were published in the January 2008 edition of the Journal of Medical Entomology. Although ivermectin is not well-absorbed through the skin, some public health advocates are concerned about its use on humans for lice and scabies. The National Pediculosis Association (NPA), a non profit agency, directs parents, health care professionals and child care providers to safer head lice control options via a standardized prevention approach focusing on routine screening, early detection and thorough combing and manual removal of lice and nits. NPA promotes this as a rational strategy over chasing lice with pesticides that offer more risk than benefit and have a well-documented history of lice resistance and failure.Most products used to treat head lice contain the insecticide pyrethrum, or its synthetic cousin permethrin, as the active ingredient. Over the past two decades, resistance to these chemicals has become a serious […]

(Beyond Pesticides, March 3, 2008) In a five-year study of the Chesapeake Bay, the nation’s largest estuary, the U.S. Geological Survey (USGS) found that, “Synthetic organic pesticides and their degradation products have been widely detected at low levels in the watershed, including emerging contaminants such as pharmaceuticals and hormones.“ The report finds that concentrations of DDT, while still present, have declined since the 1970s when it was phased out. The findings are contained in a report entitled Synthesis of U.S. Geological Survey Science for the Chesapeake Bay Ecosystem and Implications for Environmental Management. The study is a part of the Chesapeake Bay Program (CBP), which is a multi-agency partnership working to restore the Bay ecosystem. According to the report introduction, “In 2005, which represented the mid-point of the Chesapeake 2000 agreement, there was growing concern at all levels of government and by the public that ecological conditions in the Bay and its watershed had not significantly improved. The slow rate of improvement, coupled with the projected human-population increase in the Bay watershed, implied that many desired ecological conditions will not be achieved by 2010. The Government Accountability Office (2005) recommended that the CBP complete efforts for an integrated assessment approach […]

(Beyond Pesticides, February 29, 2008) The National Park Service (NPS) recently released a report documenting airborne pesticides.  The report of the  Western Airborne Contaminants Assessment Project (WACAP), with data collected from 2002 to 2007, found high concentrations of “numerous” airborne contaminants, including current and former use pesticides. Contamination is widespread throughout twenty parks throughout the western United States and Alaska, exceeding consumption levels for humans and wildlife in some areas. According to the report, the contaminants of second and third “highest concern” are “Dieldrin – an acutely toxic insecticide banned from use in the U.S. since 1987 that decreases the effectiveness of the immune system” and “DDT – an insecticide banned in the U.S. since 1972 that reduces reproductive success.” NPS also reported that Dieldrin and DDT levels exceeded the threshold for recreational fishermen in several parks, and Dieldrin levels exceeded that for subsistence fishermen in all but Olympic National Park. Fish-eating birds are also at risk in some parks. While NPS could not establish a correlation between contaminant levels and fish reproductive effects due to small sample size, two parks produced individual “intersex” fish. However, NPS stated, “This condition is commonly associated with exposure to certain contaminants (e.g., dieldrin […]

(Beyond Pesticides, February 28, 2008) Earthworms studied in agricultural fields have been found to contain chemicals from household products (including the widely marketed triclosan, a hazardous antimicrobial) and manure, indicating that such substances are entering the food chain. U.S. Geological Survey (USGS) Scientists and their colleague from Colorado State University at Pueblo published their findings in Environmental Science and Technology. The study results demonstrate that organic chemicals introduced to the environment via land application of biosolids, the solid byproduct of wastewater treatment, and manure as fertilizers are transferred to earthworms. Earthworms continuously ingest soils for nourishment and can accumulate the chemicals present in the soil.The scientists collected soil and earthworms from three agricultural fields””a soybean field fertilized with biosolids, a corn field fertilized with swine manure, and a soybean field that had received no applications of either biosolids or manure for at least 7 years. The chemicals investigated are considered indicators of human and animal waste sources and include a range of active ingredients in common household products such as detergents, antibacterial soaps, fragrances, and pharmaceuticals. All of these chemicals tend to be concentrated in the municipal waste distribution and disposal process and are referred to as anthropogenic waste indicators […]

(Beyond Pesticides, February 26, 2008) The United Farm Workers of America, Beyond Pesticides and others, represented by lawyers from Earthjustice, argued in federal court that the Environmental Protection Agency’s (EPA) decision to allow the use of azinphos-methyl until 2012 was unconscionable. The plaintiffs say EPA did not consider harm to farmworkers and their families, or to rivers, lakes and salmon, and the agency should be forced to reconsider. “There are workers getting sick,” Patti Goldman, a lawyer for Earthjustice, told U.S. District Judge Ricardo S. Martinez. “This isn’t just hypothetical. There are workers being taken out of the field.”The AP reports that Cynthia Morris, a Justice Department lawyer who argued on the agency’s behalf, told the judge that the short-term benefits of allowing growers to keep using AZM for the next several years outweigh the potential harm. She argued that the agency’s decision was reasonable, and failed to meet the “arbitrary and capricious” standard for the judge to undo it.In November 2006, EPA decided that AZM poses unreasonable adverse effects and must be banned but allowed its continued use on fruit crops for six more years — until 2012 — and on nut crops for three more years — until […]

(Beyond Pesticides, February 20, 2008) Pesticides that run off agricultural land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system, according to researcher Nathaniel Scholz, PhD, a zoologist with the National Oceanic and Atmospheric Administration (NOAA) in Seattle. Dr. Scholz, who presented his findings at the symposium entitled From Kitchen Sinks to Ocean Basins: Emerging Chemical Contaminants and Human Health,  which was organized by NOAA and hosted at the American Association for the Advancement of Science (AAAS) Annual Meeting, had previously looked at the effects of individual pesticides. However, to get a more realistic idea of exposure, combinations of several pesticides were used and juvenile salmon exposed to them two at a time. The results surprised Dr. Scholz and his team. The total impact observed from combined pesticides was greater than the sum of the individual pesticides, demonstrating a synergistic effect. Some pesticides that were not deadly when tested in individual trials killed all salmon exposed to combinations. A mixture of the pesticides diazinon and malathion, exhibited the greatest synergistic effect and killed all the salmon exposed to them, even at the lowest concentrations. “It was eye opening,” Dr. […]

(Beyond Pesticides, February 19, 2008) Common household chemicals and widespread pollutants are changing male reproductive health and impacting sexual function, development and cancer rates of today’s generations and possibly their offspring, according to more than 15 years of research by a Colorado State University expert. For example, one study looking at sperm counts globally from 1940, when chemicals first began to be widely produced, to the 1990s, indicates a 1.15 percent per year decline in sperm counts. These declines may be linked to chemical exposure.Rao Veeramachaneni, BVSc, MScVet, PhD, a biomedical sciences professor in the College of Veterinary Medicine and Biomedical Sciences, has found that chemicals including pesticides, common pollutants in ground water, and chemicals in plastics, make-up and nail polish are on a growing list of culprits causing developmental abnormalities such as impaired sperm quality and impotence. Reproductive health can be compromised if males are exposed at various times in life spanning from in utero up to adulthood.Dr. Veeramachaneni’s findings span the globe and are across species lines, from humans to horses, wildlife to frogs. His research, coupled with the collective findings of other experts in the field, indicates a strong link related to pollutants, and incidence of such […]

(Beyond Pesticides, February 14, 2008) Researchers have found what they are calling the first insect resistance in the field to genetically engineered plants that are modified to produce an insecticide called Bacillus thuringiensis, or Bt. The University of Arizona (UA) researchers, who have previously received research support from Monsanto and Cotton, Inc., are supportive of bioengineered crops and dismiss the findings of resistance, given that they are only in cotton and no other crops. The report, “Insect resistance to Bt crops: evidence versus theory,” is due out in the February issue of Nature. Concern about resistance has raised fears in the organic community that Bt, derived from natural soil bacterium, would be rendered ineffective as insect resistance spreads and this natural control collapses over time.In organic systems, composted manures and cover crops replace synthetic fertilizers, innovative weeding strategies are used instead of herbicides, beneficial insects and trap crops control insect pests, and alternatives to toxic defoliants prepare plants for harvest. Bt-resistant populations of the insect bollworm, Helicoverpa zea, were found in more than a dozen crop fields in Mississippi and Arkansas between 2003 and 2006. The bollworm resistance to Bt cotton was discovered when a team of University of Arizona […]

(Beyond Pesticides, February 13, 2008) The publication of a federal study undertaken by the Centers for Disease and Control (CDC) has been blocked for more than seven months because it contains “alarming information” of evidence of elevated infant mortality and cancer rates in the region surrounding the Great Lakes.The report entitled, Public Health Implications of Hazardous Substances in the Twenty-Six U.S. Great Lakes Areas of Concern, was commissioned by the International Joint Commission (IJC), an independent organization that advises the U.S. and Canadian governments on the use and quality of boundary waters between the two countries, and compiled by the CDC’s Agency for Toxic Substances and Disease Registry (ATSDR). The report outlines the “areas of concern” in which more than nine million people in major metropolitan areas as Chicago, Cleveland, Detroit, and Milwaukee, face higher health risks from exposure to dioxin, PCBs, pesticides, lead, mercury, or six other hazardous pollutants.Contributors to the report include senior experts from the Environmental Protection Agency, CDC, universities, as well as federal and state researchers. These experts have been reviewing data since 2004 and have found low birth weights, elevated rates of infant mortality and premature births, and elevated death rates from breast cancer, colon […]

(Beyond Pesticides, February 8, 2008) The Environmental Protection Agency (EPA) is asking for public input on its review of the chemical endosulfan, an antiquated and dangerous insecticide. Now is the time to go on record to protect children, farmworkers and rural communities from this harmful nerve toxin. Used in the U.S. on tomatoes, cotton and other crops, endosulfan harms the hormone system, and low levels of exposure in the womb have been linked to autism, male reproductive harm, and other birth defects. Acute poisoning can cause headaches, nausea, vomiting, convulsions, and in extreme cases, unconsciousness and even death. EPA’s own analysis shows that endosulfan endangers workers who handle it directly and those who work in endosulfan-treated fields. Endosulfan travels great distances, accumulates up the food chain, and poses grave risks to aquatic ecosystems. The European Union and several other countries have already banned endosulfan, and alternatives are available. It’s time the U.S. does its part to protect communities and the environment at home and around the world from this persistent organic pollutant. TAKE ACTION: Let EPA know that continued use of this unnecessary poison is unacceptable. Add your name to the petition today and forward to as many people as […]
