(Beyond Pesticides, March 5, 2009) A new study published in the March 2009 issue of Environmental Health Perspectives finds that pesticide combinations cause more harm to endangered salmon than ndividual pesticide exposure. This means that single-pesticide risk assessments required by the Environmental Protection Agency (EPA) inadequately assess hazards. Mixtures of organophosphate and carbamate pesticides are commonly detected in freshwater habitats that support threatened and endangered species of Pacific salmon. According to the researchers from the National Oceanic and Atmospheric Administration (NOAA) Fisheries and Washington State University, these pesticides inhibit the activity of acetylcholinesterase (AChE) and thus have potential to interfere with behaviors that may be essential for salmon survival. The researchers measured brain AChE inhibition in juvenile coho salmon exposed to sublethal concentrations of the organophosphates diazinon, malathion, and chlorpyrifos, as well as the carbamates carbaryl and carbofuran. The pesticides were tested individually and in combination. They plotted AChE levels on a curve to determine whether the toxicologic responses to binary mixtures were additive, antagonistic (lesser than additive) effect, or synergistic (greater than additive). The authors observed addition and synergism, with a greater degree of synergism at higher exposure concentrations. Several combinations of organophosphates were lethal at concentrations that were […]

(Beyond Pesticides, February 27, 2009) Twenty-six leading corn insect scientists at public research institutions submitted a comment to the Environmental Protection Agency (EPA) which charges that patent-holding companies, including Monsanto, Syngenta, and others, interfere with their genetic engineering (GE) research on crops. The statement says, “Technology/stewardship agreements required for the purchase of genetically modified seed explicitly prohibit research. These agreements inhibit public scientists from pursuing their mandated role on behalf of the public good unless the research is approved by industry. As a result of restricted access, no truly independent research can be legally conducted on many critical questions regarding the technology, its performance, its management implications, IRM, and its interactions with insect biology. Consequently, data flowing to an EPA Scientific Advisory Panel from the public sector is unduly limited.” The names of the 26 scientists were withheld from the public docket “because virtually all of us require cooperation from industry at some level to conduct our research.” The stewardship agreements, which are intended to ensure that farmers honor the companies’ patent rights, do not allow planting GE crops for research. These have been in place for years, but according to the New York Times, scientists have now spoken out […]

(Beyond Pesticides, February 25, 2009) After three years of legal battle, the North Carolina Pesticide Board on February 19, 2009 fined Florida-based Ag-Mart Produce Inc. a substantially lower fine of $3,000 than the originally proposed $185,000, after deciding that it can only prove six of about 200 worker safety accusations that had been levied against the company. This comes less than a month after the unprecedented ruling against Ag-Mart in New Jersey, where the company was ordered to pay penalties of more than $931,000 for misusing pesticides and jeopardizing the health and safety of workers in its New Jersey farm fields and packing houses. The Florida-based company, described as one of the biggest pesticide offenders, has been accused of routinely exposing hundreds of workers to toxic chemicals. Investigators in North Carolina, Florida and New Jersey, the three states where the international company grows its tomatoes, scrutinized the company’s records and charged it with ignoring laws intended to keep workers safe from toxic pesticide residue. The investigators alleged workers were sent into the fields too soon after dangerous chemicals had been sprayed. The case started three years ago when some workers gave birth to babies with severe birth defects. One mother […]

(Beyond Pesticides, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, February 12, 2009) Genetically modified (GM) crops are benefiting biotech food giants instead of the world’s hungry population, which is projected to increase to 1.2 billion by the year 2025 due to the global food crisis, according to a report released yesterday by the Center for Food Safety and Friends of the Earth International. The report, “Who Benefits From GM Crops: Feeding the Biotech Giants Not the World’s Poor,” explains how biotech firms like Monsanto are exploiting the dramatic rise in world grain prices that are responsible for the global food crisis by sharply increasing the prices of GM seeds and chemicals they sell to farmers, even as hundreds of millions go hungry. The findings of the report support a comprehensive United Nations’ assessment of world agriculture in the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD), which in 2008 concluded that GM crops have little potential to alleviate poverty and hunger in the world. IAASTD experts recommended instead low-cost, low-input agroecological farming methods. “U.S. farmers are facing dramatic increases in the price of GM seeds and the chemicals used with them,” said Bill Freese, science policy analyst at the US-based Center for Food Safety […]

(Beyond Pesticides, February 11, 2009) Connecticut lawmakers are taking an interest in the much debated cause of a massive die-off of lobsters that has all but wiped out the state’s 40 million dollar industry, according to the Easton Courier. Fishermen and environmentalists blame the use of the insecticide malathion, a hazardous organophosphate, currently used in community mosquito eradication programs, however the state Department of Environmental Protection (DEP) argues that there is not enough scientific data to lead to the banning of the chemical. The huge die-off of lobsters began in 1999, days after towns in Fairfield County, Westchester County and Long Island, as well as New York City, sprayed malathion to kill mosquitoes carrying the West Nile virus. Also at that time, remnants of hurricane Floyd drenched the state and washed the pesticide into Long Island Sound. The DEP, however, says the storm caused many other factors that led to the mass die-off. However, the lobster population has yet to recover. State lawmakers find DEP’s position on malathion puzzling. Rep. Richard Roy (D-Milford), chair of the House Environment Committee, and Senate Assistant Majority Leader Bob Duff (D-Norwal) are questioning DEP about its efforts to restore the state’s lobster industry while […]

(Beyond Pesticides, February 9, 2009) Baldemar Velásquez, president of the Farm Labor Organizing Committee (FLOC), AFL-CIO, will be speaking at Bridge to an Organic Future, the 27th National Pesticide Forum, April 3-4, 2009 in Carrboro, NC. FLOC, founded by Mr. Velásquez in 1967, is both a social movement and a labor union focusing on migrant workers in the agricultural industry. The FLOC vision emphasizes human rights as the standard and self-determination as the process. The union struggles for full justice for those who have been marginalized and exploited for the benefit of others, and has sought to change the structures of society to enable these people a direct voice in their own conditions. FLOC President Baldemar Velásquez was raised as a migrant farmworker. Since his childhood, he has worked in the fields and orchards of many states from Texas to the Midwest. He suffered the oppression and discrimination of migrant workers, and watched his parents humiliated many times from the injustices they experienced trying to support their family. Finally, after one incident when his father was cheated out of promised wages in front of the family, Baldemar began organizing migrant workers to stand up for their rights. Following the model […]

(Beyond Pesticides, February 9, 2009) The U.S. Environmental Protection Agency (EPA) is currently soliciting comments on Monsanto’s second application to extend its experimental use permit for soybeans genetically engineered (GE) with the soil bacterium Bacillus thuringiensis (Bt). This will be the new administration’s first test on how it handles the issues surrounding GE crops. Among a number of concerns regarding GE crops, crops engineered to contain Bt threaten the long-term efficacy of Bt, which is an approved insecticide in organic farming. Monsanto’s permit on these GE soybeans was first granted by EPA in September 2007 and then extended in April 2008. Under the permit, plantings are permitted through July 31, 2009. Monsanto is requesting to extend the experimental program until December 31, 2010 and amend it by conducting tests with up to 0.466 pounds of Bt Cry1Ac protein in soybeans on 1,362 acres, according to the February 4th Federal Register notice. The testing trials will take place in Arkansas, Illinois, Indiana, Kentucky, Maryland, Missouri, North Carolina, Puerto Rico, South Carolina, and Virginia. Following the review of the application and any comments and data received in response to this solicitation, EPA will decide whether to issue or deny the EUP request, […]

(Beyond Pesticides, January 14, 2009) Two-headed bass found in the Noosa River are at the center of a controversy surrounding pesticide drift from neighboring farms in Queensland, Australia. The pesticides, endosulfan and carbendazim, have been implicated in the contamination of the river, which has yielded thousands of chronically deformed fish. Experts believe that the mutated fish, which survive only 48 hours after hatching, are the victims of pesticide drift from neighboring macadamia nut farms that routinely use endosulfan and the fungicide, carbendazim. Aquatic health expert and vice-president of the Australian College of Veterinarian Scientists’ Aquatic Animal Health Chapter, Matt Landos, PhD, has been investigating the phenomenon and concludes that there were no other probable causes to explain the fish and larval mortality. Dr. Landos documented evidence and completed a report which was sent to the state’s Department of Primary Industries and Fisheries last year. “The timing between the mist spraying and the affected larvae fits hand in glove,” Dr. Landos said. His report also found that chickens, sheep and horses raised at nearby fish hatcheries are also recording abnormally high levels of fetal deaths and birth defects. Gwen Gilson, who runs a Boreen Point fish hatchery, says she has observed […]

(Beyond Pesticides, January 9, 2009) Environmental Toxicology and Chemistry has published a study (Vol. 27(12):2496—2500) entitled “Effects of Malathion on Embryonic Development and Latent Susceptibility to Trematode Parasites in Ranid Tadpoles.” It shows that malathion used as an agricultural insecticide is responsible for interfering with the normal development of pickerel frog embryos, thus leaving them more susceptible to parasite invasion. Malathion is present in natural water sources that have been exposed to urban and agricultural runoff. This organophosphate pesticide can be applied by planes in mosquito control program, and as esult enters water from the air. Although direct lethal and sublethal effects of chemical contaminants have been documented, latent and long-term effects have been less well documented. Therefore, researchers sought to fill this knowledge gap and found, as suspected, that tadpole survival rates decreased and malformations and susceptibility to parasite encystment rates increased as a result of exposure to malathion concentrations mimicking those found in actual water sources. Tadpoles are being exposed to increasing numbers of parasites in waters that are warming as a result of global climate change, and the researchers who performed this study speculate that, as a consequence, those exposed to malathion will have weakened immune systems […]

(Beyond Pesticides, January 8, 2009) Washington State’s model health protection programs are expected to be hit hard by Governor Chris Gregoire’s proposed budget cuts despite the minimal costs of running these essential programs, according to local activists in the state. The governor’s proposed budget will decimate the Washington Department of Health (DOH) Pesticide Program, including the Pesticide Incident Reporting and Tracking (PIRT) program, and the state’s Poison Control Center. Farm workers, children and the uninsured will likely be most affected. The proposed budget imposes almost no cuts to entities supported by the agrochemical industry. According to Carol Dansereau, an attorney with the Farm Worker Pesticide Project, and Liesl Zappler, PIRT Panel’s public member, the proposed cuts will eliminate half of the DOH’s Pesticide Program staff. DOH staff-time goes to pesticide incident interviews, toxicology research, sampling, gathering medical and spray records, analyzing and reviewing data, transmitting data, and writing reports including the PIRT report. DOH also works with growers and applicators to prevent accidental poisonings. The proposed DOH budget cuts also explicitly eliminate the PIRT Panel and its reporting requirements even though the PIRT Panel activities costs’ are minimal. Last year, DOH contributed $13,000 to PIRT; and with cuts instituted this […]

(Beyond Pesticides, December 15, 2008) Striped bass in the San Francisco Estuary are contaminated before birth with a toxic mix of pesticides, industrial chemicals and flame retardants that their mothers acquire from estuary waters and food sources and pass on to their eggs, according to a new study by University of California Davis researchers. Using new analytical techniques, the study, “Maternal Transfer of Xenobiotics and Effects on Larval Striped Bass in the San Francisco Estuary” finds offspring of estuary fish have underdeveloped brains, inadequate energy supplies and dysfunctional livers. They grow slower and are smaller than offspring of hatchery fish raised in clean water. The findings have implications far beyond fish, because the estuary is the water source for two-thirds of the people and most of the farms in California. “This is one of the first studies examining the effects of real-world contaminant mixtures on growth and development in wildlife,” said study lead author David Ostrach, a research scientist at the UC Davis Center for Watershed Sciences. “If the fish living in this water are not healthy and are passing on contaminants to their young, what is happening to the people who use the water, are exposed to the same […]

(Beyond Pesticides, December 8, 2008) A new study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds the pesticide poisoning incidence rate among U.S. agricultural workers is thirty-nine times higher than the incidence rate found in all other industries combined. The study, “Acute Pesticide Poisoning Among Agricultural Workers in the United Sates, 1998-2005,” published in the December issue of the American Journal of Industrial Medicine, is believed to be the first detailed multi-state assessment of acute pesticide poisonings among agricultural workers. From 1998 to 2005, a total of 3,271 cases of acute occupational pesticide-related illness/injury among agricultural workers were identified in ten states. According to EPA, the Worker Protection Standards are designed to reduce the risk of injury or illness to agricultural field workers resulting from exposure to pesticides. Although the WPS was expanded in 1995 and in 2005 EPA developed a new WPS How to Comply (HTC) Manual, the NIOSH findings indicate that agricultural workers continue to have an elevated risk for acute pesticide poisoning. Furthermore, female agricultural workers experienced nearly twice the risk of pesticide poisoning of male agricultural workers. The most common factors that contributed to pesticide exposure included off-target drift, early reentry into […]

(Beyond Pesticides, December 5, 2009) On November 10, 2008, the Austrian government released a report of long term research showing genetically engineered (GE) corn fed to mice significantly reduced their fertility over three to four breeding cycles within one generation. Similar effects were found in mice fed GE corn and bred over four generations. The study, “Biological effects of transgenic maize NK603xMON810 fed in long term reproduction studies in mice,” was sponsored by the Austrian Ministry of Health, Families, and Youth, and led by Dr. Jürgen Zentek, Professor of Veterinary Medicine at the University of Vienna. Three series of experiments were done. The first was a multigeneration feeding trial in which the mice were fed and bred for four successive generations, beginning with the parents that were fed the diets from birth. The second was a multi-cycle breeding trial lasting 20 weeks in which breeding pairs of mice were fed beginning one week prior to co-habitation until the end of experiment, and allowed to go through four breeding cycles in the same generation. The third was a life-term trial involving feeding the mice without breeding from conception (via the pregnant mothers) to their eventual death. The researchers report that it […]

(Beyond Pesticides, December 2, 2008) Tributyltin (also known as TBT), a ubiquitous pollutant that has a potent effect on gene activity, could be promoting obesity, according to an article in the December issue of BioScience, the journal of the American Institute of Biological Sciences. The chemical is used in antifouling paints for boats, as a wood and textile preservative, and as a pesticide on high-value food crops, among many other applications. Tributyltin affects sensitive receptors in the cells of animals, from water fleas to humans, at very low concentrations–a thousand times lower than pollutants that are known to interfere with sexual development of wildlife species. Tributyltin and its relatives are highly toxic to mollusks, causing female snails to develop male sexual characteristics, and it bioaccumulates in fish and shellfish. Recent research has found it in deep-sea squids and octopods, and it has been banned for maritime use by an international treaty. The harmful effects of the chemical on the liver and the nervous and immune systems in mammals are well known, but its powerful effects on the cellular components known as retinoid X receptors (RXRs) in a range of species are a recent discovery. When activated, RXRs can migrate into […]

(Beyond Pesticides, November 26, 2008) On November 10, two Alaskan environmental groups sued the United States Fish and Wildlife Service (FWS) for failing to conduct a proper assessment of the environmental consequences of using herbicides to kill non-native species in Kodiak National Wildlife Refuge and the Alaska Maritime National Wildlife Refuge. The groups, Alaska Survival and Alaska Community Action on Toxics, allege that FWS sprayed hundreds of gallons of herbicide in the Kodiak National Wildlife Refuge and the Alaska Maritime National Wildlife Refuge over the past several years. In the complaint to the U.S. District Court of Alaska, the groups say FWS violated the National Environmental Policy Act (NEPA) by failing to conduct adequate investigations on the environmental impacts of pesticide use and by failing to inform the public of the practice. The lawsuit states, “(Fish and Wildlife) failed to consider the potential harm to aquatic organisms, fish, birds, insects and other non-target species, as well as the potential for adverse effects to humans visiting the area,” and that the “defendants failed to consider the effect of herbicide use on the commercial salmon fishing industry and on subsistence users.” Under NEPA, all federal agencies are required to conduct an Environmental […]

(Beyond Pesticides, November 21, 2008) On November 18, the National Marine Fisheries Service (NMFS) released a biological opinion that sets forth a plan for protecting Pacific salmon and steelhead from three toxic organophosphate pesticides. The decision comes after almost a decade of legal wrangling between salmon advocates and the federal government. In the biological opinion, federal wildlife scientists comprehensively reviewed the science regarding the impacts of pesticides on salmon and ultimately concluded that current uses of the insecticides chlorpyrifos, diazinon, and malathion jeopardize the existence of these imperiled fish. The biological opinion prescribes measures necessary to keep these pesticides out of water and to protect salmon populations in Washington, Oregon, California, and Idaho. The new mitigation measures must be implemented within one year. They include: * Prohibiting aerial applications of the three pesticides within 1,000 feet of salmon waters * Prohibiting ground applications of the three pesticides within 500 feet of salmon waters * Requiring a 20 foot non-crop vegetative buffer around salmon waters and ditches that drain into salmon habitat * Prohibiting applications of the three pesticides when wind speeds are greater than or equal to 10 mph “Keeping these pesticides out of the water is a major step […]

(Beyond Pesticides, November 17, 2008) A toxic soup of the most commonly used pesticides frequently detected in nature can adversely affect the environment and decimate amphibian populations even if the concentration of the individual chemicals are within limits considered safe, according to University of Pittsburgh research published in the online edition of Oecologia. The results of this study build on a nine-year effort to understand potential links between the global decline in amphibians, routine pesticide use, and the possible threat to humans in the future. Amphibians are considered an environmental indicator species because of their unique sensitivity to pollutants. Their demise from pesticide exposure could foreshadow the fate of less sensitive animals, according to study author Dr. Rick Relyea, Ph.D., an associate professor of biological sciences in the University of Pittsburgh’s School of Arts and Sciences. Leopard frogs, in particular, are vulnerable to contamination; once plentiful across North America, their population has declined in recent years as pollution and deforestation has increased. Dr. Relyea exposed gray tree frog and leopard frog tadpoles to small amounts of the ten pesticides that are widely used throughout the world. Dr. Relyea selected five insecticides: carbaryl, chlorpyrifos, diazinon, endosulfan, and malathion; and five herbicides: […]

(Beyond Pesticides, November 6, 2008) Agricultural biotech seed and chemical giant Monsanto will acquire Aly Participacoes Ltda., a Brazilian company involved in breeding sugar cane, and has already begun work to develop genetically engineered (GE) Roundup Ready (herbicide resistant) sugarcane. The deal for $290 million comes at the same time grain giant Archer Daniels Midland (ADM) is set to invest $375 million in a joint venture with a Brazilian firm to produce sugarcane-based ethanol. Amidst numerous other concerns with the widespread adoption of GE crops and the proliferation of crops grown for biofuels around the world is the threat of increased pesticide use. Roundup Ready crops, which are genetically engineered to be resistant to Monsanto’s best selling herbicide Roundup (active ingredient glyphosate https://www.beyondpesticides.org/gateway/pesticide/glyphosate.htm) have been a boon to Monsanto’s profits, but not without environmental costs. Currently grown Roundup Ready crops include soy, corn, canola, cotton, and sugar beets. The crops’ resistance to glyphosate enables the use of the herbicide during the growing season without harming the crop itself. Glyphosate is now the number one herbicide in the United States. This has serious implications for public health and the environment, as glyphosate has been linked to cancer, reproductive effects, kidney and […]

(Beyond Pesticides, October 23, 2008) Researchers in Illinois have developed a genetically modified grape that is resistant to the toxic herbicide 2,4-D. The development is in response to serious losses grape growers in the Midwest have suffered as a result of the surrounding use of 2,4-D on grain crops. While the new variety may mean that Midwest grape growers can continue to grow grapes successfully, it does not address the underlying problem –excessive use of toxic herbicides that are prone to drift thereby contaminating other crops, air and water, and threatening human and environmental health. Herbicide resistant crops were first introduced in 1996 with Roundup Ready soybeans, which were engineered to enable the spraying of Roundup (active ingredient glyphosate) without harming the soybean plants. Since then other Roundup Ready varieties, such as corn, cotton, canola, and sugar beets, have been introduced and are grown in the U.S. and abroad. In a victory for Beyond Pesticides and other environmental groups who see the proliferation of genetically engineered crops as a threat to health, the environment and organic farmers’ livelihoods, a federal court upheld a ban on Roundup Ready alfalfa in September. The widespread adoption of Roundup Ready crops has led to […]

(Beyond Pesticides, October 20, 2008) Organophosphate (OP) pesticides are among a toxic soup of hazardous chemicals found in the bodies of pregnant women, according to an National Institutes of Environmental Health Sciences (NIEHS) led study doi:10.1016/j.envres.2008.07.014 published in the October issue of the journal Environmental Research. The population-based birth cohort study analyzed urine specimens of one hundred pregnant women. The study builds on the existing body of evidence that shows that low-level exposure to chemicals impact human health, especially pregnant women and their children. The research is part of the Generation R Study, which includes 9778 participants in the Netherlands and focuses on growth and physical development, behavioral and cognitive development, childhood diseases and health, and health care for pregnant women and children. The Generation R Study allows the researchers to follow-up with the study participants and “provides an opportunity to efficiently address questions regarding the reproductive and development effects of prenatal exposures.” Besides finding high levels of OP pesticides, the researchers find some suspected endocrine disrupting compounds including bisphenol A (BPA) and phthalates. Animal studies show that these chemicals can affect brain and reproductive development. According to the researchers, exposure to OP pesticides and some phthalates were significantly higher […]

(Beyond Pesticides, October 15, 2008) Researchers have developed a potential new method of making plants significantly more resistant to pests. Scientists from Lancaster University (UK) have conducted early trials whose results have yielded promise to greatly reduce pesticide by first treating seeds with a chemical that is naturally produced by plants. This new method involves dipping seeds in jasmonic acid, a plant derived chemical that provides a natural defense against pests. When threatened by plant-eating insects, plants release jasmonic acid as a chemical signal to warn other parts of the plant to mobilize their pest defenses in order to make the plant difficult to digest. Jasmonic acid has long been used as a repellent for pests like mites, caterpillars and aphids when sprayed onto crops. Jasmonic acid however, also acts as a growth inhibitor and sprayed plants do not grow very well, but scientists at Lancaster University’s Environment Centre have found that plants grown from seeds first dipped in jasmonic acid are also more pest resistant without any loss of growth. The best results were on tomato plants, where attacks by red spider mites were reduced by 80%, aphid attack was reduced by 60% and caterpillar damage was down by […]
