(Beyond Pesticides, April 11, 2008) The United States House of Representatives’ Committee on Oversight and Government Reform released a report last month on the Food and Drug Administration (FDA) failures that lead to the E.coli outbreak in spinach, which peaked in September 2006. When E.coli was discovered in package spinach, critics of organic agriculture and parts of the media were quick to target organic spinach as the source (starting something of a debunking “war”). NBC’s Today Show erroneously blamed organic agriculture (to which Beyond Pesticides responded here). However, the Congressional report lists a variety of failures on the part of FDA to ensure safe handling and packaging of spinach, citing a limited number of inspections and failure to enforce adequate sanitation and processing practices. The major faults found by the committee range from frequency and thorughness of inspections, to lack of enforcement, including: Packaged fresh spinach facilities were inspected only once every 2.4 years, less than half of FDA’s stated goals. FDA observed objectionable conditions during 47% of the packaged fresh spinach inspections [60% of which pertained to facility sanitation]. Despite observing objectionable conditions in packaged fresh spinach facilities, FDA took no meaningful enforcement action. FDA overlooked repeated violations. FDA […]

(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 8, 2008) A team of University of Michigan scientists discover interactions between genes and organophosphate exposure cause some forms of motor neuron disease (MND). The study, which appears in the March issue of the American Journal of Human Genetics, shows the mutations in one key gene (neuropathy target esterase, or NTE) that causes a previously unknown type of inherited MND. The scientists also find the mutations caused changes in a protein already known to be involved when people develop neurologic disorders as a result of exposure to toxic organophosphate chemicals commonly used in solvents and insecticides and also as “nerve gas” agents. Motor neuron disease is a rare, devastating illness in which nerve cells that carry brain signals to muscles gradually deteriorate. One form of it is Lou Gehrig’s disease or ALS (amyotrophic lateral sclerosis). For most MND patients, the cause is unknown. Figuring out why these people develop the disease, which causes muscles to weaken, atrophy and cease to function, is an important step in developing therapies to treat or prevent motor neuron disease. Motor neuron disease affects five per 100,000 people. “Our findings support the possibility that toxic organophosphates contribute to motor neuron disease in […]

(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 (ĂŽÂĽg), and the average indoor exposure from naphthalene at less than 1ppb. While airing did reduce […]

(Beyond Pesticides, April 1, 2008) On March 27, many distinguished environmental health and justice advocates in addition to political leaders gathered in Los Angeles, CA to express their gratitude & praised the efforts of the Los Angeles Unified School District, (2nd largest in the nation) for working cooperatively for a decade with California Safe Schools (CSS), a children’s environmental health organization in creating the most protective pesticide policy for schools in the country. California Safe Schools (CSS) was formed by Robina Suwol in 1998, following an incident with her then 6-year-old son Nicholas, a student at Sherman Oaks Elementary School. Unaware students were present, a school gardener in a hazardous materials suit sprayed the herbicide Princep, creating a cloud of pesticide mist students were forced to walk through in order to reach their classrooms. Later, Nicholas, whose asthma had previously been under control, experienced a life-threatening asthma attack. Ms. Suwol’s initial research on a web site sponsored by Cornell University revealed that a single exposure to Princep could be very dangerous to children, and may cause tremors, convulsions & paralysis, among other symptoms. Further investigation revealed that many chemical pesticides commonly used in schools carry significant risks to growing children […]

(Beyond Pesticides, March 31, 2008) Researchers studying related individuals who share environmental and genetic backgrounds find an association between pesticide use and Parkinson’s disease. The strongest links were between the disorder and use of herbicides and insecticides, such as organochlorines and organophosphates. The study, “Pesticide exposure and risk of Parkinson’s disease: a family-based case-control study,” was published March 28 online in the journal BMC Neurology. The research team from Duke University Medical Center and the University of Miami Miller School of Medicine Morris K. Udall Parkinson Disease Research Center of Excellence recruited 319 patients and over 200 relatives. They used telephone interviews to obtain histories of pesticide exposure, living or working on a farm, and well-water drinking. No association was found between Parkinson’s disease and well-water drinking or living or working on a farm, which are two commonly used proxies for pesticide exposures. Parkinson’s disease is a common neurological disorder affecting about 1 million people in the U.S. The disorder typically develops in later life resulting in symptoms such as tremors and muscle rigidity. Although variations in several genes have been identified that contribute to the disease, these rare genetic defects account for a small proportion of the overall prevalence […]

(Beyond Pesticides, March 28, 2008) Three years ago, Carlos Candelario was born without arms or legs and with spinal and lung deformities, birth defects caused by his mother’s exposure to multiple pesticides while working in Ag-Mart Produce fields during her pregnancy. His parents, Francisca Herrera and Abraham Candelario, sued the company in 2006, and last week’s settlement will provide for Carlos for the rest of his life, pending a judge’s approval. “I am as gratified about this case as any I’ve ever handled,” said attorney Andrew Yaffa. “This child has tremendous needs and needed somebody willing to speak on his behalf. Every medical need will be taken care of as a result of this settlement.” Ag-Mart has a history of state pesticide violations and use of extremely toxic pesticides (although in 2005, the company did agree to discontinue use of chemicals linked to reproductive risks, excepting methyl bromide, which is still in use). The company grows “UglyRipe” heirloom tomatoes and Santa Sweets grape tomatoes in a chemical-intensive operation. Ms. Herrera and Mr. Candelario worked alongside other migrant workers in North Carolina and Florida fields at the time of Ms. Herrera’s exposure. Both Florida and North Carolina have published reports on […]

(Beyond Pesticides, March 25, 2008) According to a new study, Simplifying the Pesticide Risk Equation: The Organic Option, converting the nation’s eight million acres of produce farms to organic would reduce pesticide dietary risks significantly. The report provides the first-ever quantitative estimate of the degree to which pesticide risks from food can be eliminated through adoption of organic farming methods says report author Charles Benbrook, Ph.D., the Organic Center’s chief scientist. Less than three percent of the nation’s cropland produces fruits and vegetables. Yet, according to the report, these crops account for most of the pesticide risks from dietary exposure in domestically produced foods. If converting domestic cropland of organic is coupled with consumers choosing only imported produce that is certified organic, dietary pesticide exposure is reduced by 97 percent.Other findings in the report include: An analysis of the significantly greater pesticide risks linked to consumption of imported conventionally-grown fruits and vegetables, as compared to domestically-grown produce. Rankings of dietary risk levels in select conventionally-grown fruits and vegetables, arranged to help guide consumers seeking to minimize pesticide risks. Suggestions on how to meet dietary guidelines for fruit and vegetable intake in the winter, while also reducing pesticide exposures. An overview […]

(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. […]
