(Beyond Pesticides, October 9, 2015) Last week, the Environmental Protection Agency (EPA) released preliminary human health and ecological risk assessments for seven organophosphate pesticides (OPs) and announced the public open comment period for those chemicals. These risk assessments come as a result of the required periodic registration review, as required by  the Federal Insecticide, Fungicides, and Rodenticide Act. In general, OPs are highly toxic and many have been voluntarily removed from the market, considerably restricted, or denied reregistration. Unfortunately, EPA continues to rely on risk mitigation for individual OPs instead of phasing them out altogether. Seven OPs  —dimethoate, dictrotophos, chloyrophos-methyl, tribufos, terbufos, profenofors, and ethoprop—are among the first wave of chemicals whose preliminary risk assessments have been completed under the registration review program. Each of these was found by EPA to inhibit the enzyme acetylcholine esterase (AchE), which ultimately leads to neurotoxic  central nervous system effects. This information is not new, however. In 2012, University College London found long-term low-level exposure to OPs produces lasting damage to neurological and cognitive functions. In 2013, at least 25 children died after eating school lunches contaminated by OPs. One OP in particular, chlorpyrifos, chlorpyrifos (Dursban), is currently under petition for the same […]

(Beyond Pesticides, September 8, 2010) The U.S. Environmental Protection Agency (EPA) has received a new Biological Opinion from the National Marine Fisheries Service (NMFS) with a finding that the application of products containing any of 12 organophosphate (OP) pesticides are likely to jeopardize federally listed threatened or endangered Pacific salmon and steelhead and their designated critical habitat. The 12 OPs addressed in this Biological Opinion, issued under the Endangered Species Act, are azinphos-methyl, bensulide, dimethoate, disulfoton, ethoprop, fenamiphos, methamidophos, methidathion, methyl parathion, naled, phorate, and phosmet. This opinion concludes that EPA’s registration of pesticides containing bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet are each likely to jeopardize the continued existence of one or more of the 28 endangered and threatened Pacific salmonids and are each likely to destroy or adversely modify designated critical habitat for one or more of the 28 threatened and endangered salmonids. NMFS reached this conclusion because predicted concentrations of these seven pesticides in salmonid habitats, particularly in floodplain habitats, are likely to cause adverse effects to at least one listed Pacific salmonids including significant reductions in growth or survival. EPA’s registration of bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet is also likely to result […]

(Beyond Pesticides, September 10, 2008) Following the report released by the National Marine Fisheries Service that identified 37 pesticides that pose risks to salmon and steelhead, Oregon state officials are moving ahead to set new safety benchmarks for seven pesticides of priority concern. A team from the Oregon Water Quality Pesticide Management Program identified seven priority hazardous pesticides: azinphos-methyl, chlorpyrifos, dacthal, diazinon, endosulfan, simazine and ethoprop, based on water-quality monitoring in five Oregon watersheds, including the Pudding River near Salem, as well as the Clackamas, Yamhill, Hood and Walla Walla watersheds. Three pesticides, azinphos-methyl, diazinon and chlorpyrifos have been detected at concentrations that exceed federal aquatic criteria in the Clackamas River Basin (See report here). Chlorpyrifos was detected at maximum levels more than twice the federal standard. The National Marine Fisheries Service report on the ecological damage associated with pesticide use reveals “overwhelming evidence” to suggest that 37 pesticides, including these seven, increase the chance of extinction for protected salmon and steelhead. The state is now turning to its own team of experts to set stringent benchmarks based on existing research on these chemicals of concern. Generally the U.S. Environmental Protection Agency (EPA) is charged with developing water quality standards […]

(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 […]
