(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 16, 2008) Some of America’s most pristine natural places are contaminated with toxic pesticides from illegal marijuana growing operations. Recent busts in the 1800 square mile Sequoia National Park revealed the use of imported and banned herbicides and insecticides in intensive growing sites. Rat poisons, or rodenticides, were also scattered around to kill small animals who might be tempted to nibble a plant. CNN reports that “millions of dollars are spent every year to find and uproot marijuana-growing operations on state and federal lands, but federal officials say no money is budgeted to clean up the environmental mess left behind after helicopters carry off the plants,” and this environmental mess is severe. The extent of marijuana growing on federal lands is unknown, but seven hundred grow sites were discovered in California in 2007-2008. Many of these operations are run by Mexican marijuana growing cartels and the chemicals used are illegally imported from Mexico. It is estimated that 1.5 lbs of fertilizers and pesticides is used for every 11.5 plants. For the five million plants uprooted in California in 2007, this amounts to over 650,000 lbs of fertilizers and pesticides. Agent Patrick Foy of the California Department of […]

(Beyond Pesticides, October 14, 2008) Exposure to glyphosate or MCPA can more than double one’s risk of developing non-Hodgkin lymphoma (NHL), according to a new epidemiological study published in the October issue of the International Journal of Cancer. The case-control study finds a 2.02 odds ratio (OR) for exposure (two times the chance of contracting the illness) to glyphosate, a 2.81 OR for exposure to MCPA, and a 1.72 OR for exposure to herbicides. According to EPA, glyphosate is the most commonly used pesticide in the U.S. with 103 to 113 million pounds used annually. MCPA is a phenoxyacetic acid pesticide, a family of pesticides that has previously been linked to cancer and includes 2,4-D and mecoprop (MCPP). NHL is a cancer of the immune system. There are several different types of NHL, which are differentiated by the type of immune cell that is cancerous, the characteristics of the cancerous cell, and different genetic mutations of the cancerous cells. Treatment for NHL varies depending on NHL type, patient age, and other existing medical conditions. The incidence of NHL has been increasing over the past several decades. The link between pesticides and cancer has long been a concern. While agriculture has […]

(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, August 8, 2008) University of California Davis Cancer Center physicians recently released results of research showing that Vietnam War veterans exposed to Agent Orange have greatly increased risks of prostate cancer and even greater risks of getting the most aggressive form of the disease as compared to those who were not exposed. The findings, which appear online now and will be published in the September 15 issue of the journal Cancer, are the first to reliably link the herbicide with this form of cancer by studying a large population of men in their 60s and the prostate-specific antigen (PSA) test to screen for the disease. “While others have linked Agent Orange to cancers such as soft-tissue sarcomas, Hodgkin’s disease and non-Hodgkin’s lymphoma, there is limited evidence so far associating it with prostate cancer,” said Karim Chamie, lead author of the study and resident physician with the UC Davis Department of Urology and the VA Northern California Health Care System. “Here we report on the largest study to date of Vietnam War veterans exposed to Agent Orange and the incidence of prostate cancer.” Chamie also said that, unlike previous studies that were either too small or conducted on men […]

(Beyond Pesticides, June 2, 2008) Residential properties in Saginaw, Michigan contain unacceptably high levels of dioxin contamination, according to U.S. Environmental Protection Agency (EPA) Region 5. Soil from the Riverside Boulevard area, a neighborhood along the Lower Tittabawassee River and downstream from the Dow Chemical Company’s manufacturing plant, was recently sampled and analyzed by EPA and evaluated in collaboration with Michigan Department of Environmental Quality (MDEQ) and the Michigan Department of Community Health. Past waste disposal practices, fugitive emissions and incineration at the plant have resulted in on- and off-site contamination of nearby waterways. Dow’s manufacturing of chlorine-based products and other chemicals results in dioxins, as well as furans, chlorobenzenes and heavy metals, as byproducts. According to the Chicago Tribune, soil samples “from one yard was 23 times higher than what the EPA considers reasonable safe.” Former administrator for EPA’s Region 5, Mary Gade, had been aggressively pushing Dow to properly cleanup the area, until she was forced out, states the Chicago Tribune. Dow’s previous dioxin cleanup of the 300 residences included cleaning inside the homes and laying wood chips over the contaminated soil around the homes, which is believed to be ineffective in protecting people and wildlife from dioxin […]

(Beyond Pesticides, May 5, 2008) A new study indicates that some pesticides applied to golf courses in the Precambrian Shield of central Ontario may have an impact on aquatic organisms in adjacent watersheds. The study is published in the April issue of Environmental Toxicology and Chemistry. Golf courses affect the environment by altering the habitat through the release of nutrients and pesticides. The Precambrian Shield region of central Ontario, Canada, a major recreational area, is especially susceptible to the impacts of golf courses as a result of the geology and hydrology of the region. The Shield area is characterized by many lakes, rivers, and streams. Golf courses in this area typically place turf on top of a sand base which allows chemicals used on the courses to migrate into surrounding bodies of water. The study set out to determine (1) whether organic substances that are toxic to early life stages of fish are transported from golf courses in the Precambrian Shield and (2) whether toxic compounds occur in watersheds of golf courses at times that coincide with the application of pesticides to golf courses and other conditions conducive to surface runoff. To do so, two golf courses in the Muskoka […]

(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 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, 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 […]

November 13, 2007) Autism is on the rise, both in prevalence and incidence, and there is growing evidence that environmental insults, such as pesticides, are linked to this developmental disability. According to the latest study, published in the October issue of Environmental Health Perspectives, children born to mothers living near fields where pesticides are applied are more likely to develop autism spectrum disorders (ASDs). The authors of “Maternal Residence Near Agricultural Pesticide Applications and Autism Spectrum Disorders among Children in the California Central Valley” compared maternal pesticide exposure for 465 children with ASDs and 6,975 children without ASDs living in the same area. The research reveals that mothers who lived within 500 meters of fields sprayed with organochlorine pesticides, specifically endosulfan and dicofol, during their first trimester of pregnancy had a six times higher chance of having children with autism compared to mothers who did not live near the fields. Mark Horton, M.D., director of the California Department of Health, said the findings are exploratory and indicate that more research of the relationship between organochlorines and ASDs is needed. (See Daily News Blog posting from July 31, 2007 for further reactions from health care officials and more details about this […]

(Beyond Pesticides, August 16, 2007) The Environmental Protection Agency’s (EPA) recent decision not to go through with a Special Review of 2,4-D’s carcinogenic properties is being touted by industry as the final word that the toxic chemical “has been found to have no human carcinogenic effects,” despite significant evidence to the contrary. The Special Review has been cancelled after an industry task force poured millions of dollars into industry funded research and a public relations campaign. The pesticide 2,4-D, or 2,4-Dichlorophenoxyacetic acid, was first slated by EPA for Special Review in 1986. A few years later in a unique move, several large pesticides companies with a common interest in keeping 2,4-D on the market formed the Industry Task Force II on 2,4-D Research Data. Since then, the task force reports it has funded nearly $30 million in new research on the chemical. Industry funded research is often biased and influential in the regulatory process. The results are reported to EPA, which provides a large portion of the data the agency relies on in order to make decisions under an inadequate risk assessment review process. The task force is currently comprised of the major pesticide producers Dow AgroSciences (U.S.), Nufarm Ltd. […]

(Beyond Pesticides, August 14, 2007) In an August 8, 2007 Federal Register Notice (72 FR 44510-44511), the Environmental Protection Agency (EPA) announced its decision to not initiate a Special Review for the commonly used herbicide 2,4-D, as well as the related herbicides 2,4-DB and 2,4-DP (dichlorprop). Despite evidence to the contrary, according to the FR notice, “Based on extensive scientific review of many epidemiology and animal studies, EPA find that the weight of the evidence does not support a conclusion that 2,4-D, 2,4-DB and 2,4-DP are likely human carcinogens.” Although a mounting body of evidence links 2,4-D to various cancers, particularly non-Hodgkin’s lymphoma, EPA has been reluctant to classify it as a carcinogen in the face of industry pressure. EPA lists the herbicide in class D for carcinogenicity. Chemicals in this class are considered to have inadequate evidence for carcinogenicity, or not enough data is available. However, the link between 2,4-D and non-Hodgkin’s lymphoma has been demonstrated in the United States, Italy, Canada, Denmark, and Sweden. A 1986 National Cancer Institute (NCI) study found that farmers in Kansas exposed to 2,4-D for 20 or more days per year had a six-fold higher risk of developing non-Hodgkin’s lymphoma than non-farmers. The […]

(Beyond Pesticides, August 13, 2007) Greenland sharks, which inhabit some of the least populated regions on Earth in seemingly pristine Arctic waters, contain high amounts of human-manufactured industrial waste in their bodies, including toxic pesticide byproducts. The findings are available online in Marine Pollution Bulletin (in press), entitled “Dioxins and PCBs in Greenland shark (Somniosus microcephalus) from the North-East Atlantic.” According to the team of researchers at Stockholm University, the highest measured concentration found is for the world’s most toxic dioxin, TCDD, a compound found in the herbicide Agent Orange, which the U.S. military used during the Vietnam War. The herbicide was used for other applications from 1961 to 1971. The study also names another set of discontinued chemicals, polychlorinated biphenyls, or PCBs, as the main source of the contaminants found in the Greenland sharks. PCBs were banned in the 1970s, which illustrates how persistent such compounds are in the environment and how long-living, top predator species may carry them for decades. Project leader Dr. Åke Bergman, Ph.D., an environmental chemist at Stockholm University, told Discovery News that he and his team decided to focus on Greenland sharks since their normal lifespan may exceed 100 years, based on an annual […]

(Beyond Pesticides, July 20, 2007) Dow Chemical Company has reached agreement with the Environmental Protection Agency (EPA) to begin cleanup of dioxin contamination downstream of its Midland, Michigan facility immediately. The teratogenic (i.e. ability to cause developmental malformations) and mutagenic compounds are not only byproducts of manufacturing processes but are contained in one of Dow’s most used herbicides. Last November, Dow identified dioxin hot spots along the Tittabawassee River, but corrective action “has taken too long” according to an EPA press release. “EPA has documented that dioxin contamination in soil poses risks to human health and the environment.” Dioxins are a family of chemicals that have been linked to cancer, weakened immune systems and reproductive problems. Terry Miller, a member of Lone Tree Council, an environmental group, told the Saginaw News that EPA’s decision confirmed his suspicions that Dow was “dragging their feet” in the cleanup efforts. “There’s been a lot of print suggesting the state has been too hard on the company when it appeared that Dow was being too slow,” he said. “The federal government would seem to support that contention.” Michelle Hurd-Riddick, a spokeswoman for the Lone Tree Council, was quoted by the Saginaw News saying that […]

(Beyond Pesticides, June 14, 2007) State legislators in Massachusetts are working on a bill that would phase out the use of 10 toxic chemicals, create a system to study toxics and find safer alternatives. Many state, health, labor and environmental officials have long supported this bill, which attempts to remove many toxic components from products used in everyday materials. Chemicals like those used in pesticides, wood and those found in children’s products, are especially targeted in the Safer Alternatives Bill (H. 783 / S. 558). Organophosphates, a toxic class of pesticides developed circa World War II, have been targeted in the phase out. Commonly used against mosquitoes, organophosphates like malathion (Fyfanon), naled (Dibrom) and chlorpyrifos (Mosquitomist) have been shown to be dangerous, especially to vulnerable populations, and affect the central nervous, cardiovascular and respiratory systems. The other chemicals slated for phase out have all been linked to environmental and health concerns as well and include perchloroethylene, dioxins and furans, hexavalent chromium, polybrominated diphenyl ethers, di (2-ethylhexyl)phthalate (DEHP), 2,4-dichlorophenoxyacetic acid (2,4-D), trichloroethylene, formaldehyde and lead. If passed by the Legislature, the State Department of Environmental Protection will be charged with the task of setting timelines to phase out the chemicals after […]

(Beyond Pesticides, April 18, 2007) Two members of Oregon’s Congress have sponsored bills that, if passed, would provide schools with a no-spray buffer zone during the academic year. Among other requirements, the bills would establish separate buffers around schools for aerial spraying, backpack pesticide applications, and additional buffers around roads servicing schools during commuting hours. Senate Bill 20 (SB 20) and House Bill 2978 are sponsored by State Senator Vicki Walker, D-Eugene, and Representative Paul Holvey, D-Eugene, respectively. SB 20, the stronger of the two bills, is currently the focus of media and organizers on both sides. It is currently being reviewed by the Environmental and Natural Resources Committee, which will determine whether it should be introduced to the entire Senate. The two bills come after a Merck Foundation-funded study by Oregon Toxics Alliance and Forestland Dwellers to map pesticide applications near schools in Lane County. The study found some schools were near areas treated with aerial applications and a logging area sprayed adjacent to athletic fields. The Oregon Department of Agriculture has reported drift incidents at schools causing illness and at least one school closure (as has happened in other states). The proposed buffer zones, according to Lisa Arkin, […]

(Beyond Pesticides, March 8, 2007) It’s almost spring and soon those little yellow pesticide caution signs, signaling a pesticide application, will be popping up everywhere. Many people do not know the meaning of these pesticide warning flags. They indicate that poisonous chemicals have been applied to the turf and that everyone, especially children, should STAY OFF THE GRASS. Even a 24-hour waiting period has been shown to be inadequate, as many pesticides can persist on turf and in the soil for months, not days, after an application. Additionally, pesticides get tracked into indoor environments and persist in carpet and in household dust. Be aware of the facts about pesticides. Many people think that the pesticides wear off, and that people and pets are not being exposed. However, the Centers for Disease Control and Prevention (CDC) found multiple pesticide residues, including the herbicide 2,4-D (weed and feed products), in the bodies of children ages 6-11 at significantly higher levels than all other age categories. Herbicides such as 2,4-D and mecoprop, chemicals tied to respiratory ailments, are found in 15 percent of children tested, ages 3 to 7, whose parents had recently applied the lawn chemicals. A 2002 peer-reviewed study found children […]

(Beyond Pesticides, March 6, 2007) In a victory for Alaska’s environmental community, the state’s Department of Environmental Conservation (DEC) has denied the Alaska Railroad Corporation’s (ARRC) application to spray herbicides, citing water quality concerns. The decision effectively maintains a record of over 20 years of non-chemical vegetation management of Alaska’s railways. ARRC submitted the application to spray herbicides last year to DEC. According to DEC’s documents, the proposed treatment area included approximately 500 miles of track and 100 miles of rail yard. The spray mixture proposed would have been comprised of three pesticide products: Razor Pro (active ingredient glyphosate*), Solution Water Soluble (dimethylamine salt of 2,4-D*), and Oust Extra (sulfometuron methyl and metsulfuron methyl). The mixture would have also contained the drift retardant Alenza (proprietary polyvinyl polymer). ARRC claims on its website it has “tried to control vegetation along its track with non-chemical methods including mechanical brush-cutting, manual labor, steam and burning since 1983. Despite these efforts, the volume and location of vegetation along the track has resulted in stiff fines from the Federal Railroad Administration, the railroad’s federal regulatory agency.” Over one thousand written comments were filed with DEC, and oral testimony was given during the public participation process […]

(Beyond Pesticides, March 2, 2007) The United States Department of Agriculture’s (USDA) Pesticide Data Program (PDP) recently released its latest annual summary detailing pesticide residues in the U.S. food supply. The data, from 2005, reveals approximately two-thirds of sampled foods contained one or more pesticides at detectable levels. For the 2005 report, PDP sampled fresh and processed fruit and vegetables, soybeans, wheat, milk, heavy cream, pork, bottled water and drinking water. A total of 14,749 samples were tested for various insecticides, herbicides, fungicides and growth regulators. Twelve states reported data to comprise the report: California, Colorado, Florida, Maryland, Michigan, Minnesota, Montana, New York, Ohio, Texas, Washington and Wisconsin. Excluding drinking water, 84 percent of samples originated within the United States. Foods most likely to be consumed by infants and children are analyzed to provide data that is used in the implementation of the Food Quality Protection Act. The data is used in this context to assess dietary exposure to pesticide residues by the Environmental Protection Agency (EPA). Overall results show that, excluding drinking water samples, 36 percent of samples had more than one detectable pesticide, 30 percent had one detectable pesticide, and 34 percent did not have detectable levels of […]

(Beyond Pesticides, March 1, 2007) In 24 states throughout the country, beekeepers have been shocked to find that bees have been inexplicably disappearing at an alarming rate, according to an article in the New York Times last week. This loss of honeybees threatens not only beekeeper livelihoods but also the production of numerous crops, including California almonds, one of the nation’s most profitable crops. Although the reasons for the honeybee disappearances are unknown, pesticides may be one of the culprits. “I have never seen anything like it,” David Bradshaw, a California beekeeper, said. “Box after box after box are just empty. There’s nobody home.” Last month he discovered that half of his 100 million bees were missing. Beekeepers have fought regional bee crises before, but this is the first national affliction. Bees are flying off in search of pollen and nectar and simply never returning to their colonies. And nobody knows why. Researchers say the bees are presumably dying in the fields, perhaps becoming exhausted or simply disoriented and eventually falling victim to the cold. As researchers scramble to find answers to the syndrome they have decided to call “colony collapse disorder,” growers are becoming openly nervous about the capability […]
