(Beyond Pesticides, November 6, 2007) Reclaiming Our Healthy Future: Political change to protect the next generation, the 26th National Pesticide Forum, will be held March 14-16, 2008 at the University of California, Berkeley. The conference is convened by Beyond Pesticides, Californians for Pesticide Reform (CPR) and Pesticide Action Network North America (PANNA). Session topics include: Children’s health, Farmworker justice, Fair and healthy food, the DDT resurgence, and much more. Check the website for the weekly updates. In addition, veteran stage actress Kaiulani Lee will perform A Sense of Wonder, her one-woman play based on the life and works of Rachel Carson. The play, which is made up of mostly Carson’s own words from letters, journal entries, speeches, not only focuses on Silent Spring, but on aspects of her private life not often examined. Ms. Lee explains, “She [Carson] was very poor…She had nothing. And she changed the course of history.” Registration is $65 for members, $75 for non-members, $175 for business registrants, and $35 for students. Forum registration includes receptions, breakfast and lunch on Saturday and breakfast on Sunday, plus all plenaries, keynotes, workshops and the stage performance of A Sense of Wonder. All food will be organic. Online registration, […]

(Beyond Pesticides, October 18, 2007) Antibacterial soaps show no health benefits over plain soaps and, in fact, may render some common antibiotics less effective, says University of Michigan public health professor Allison Aiello, Ph.D. The study, “Consumer Antibacterial Soaps: Effective or Just Risky?” appears in the August edition of Clinical Infectious Diseases. In the first known comprehensive analysis of whether antibacterial soaps containing triclosan work better than plain soaps, Dr. Aiello of the University of Michigan School of Public Health and her team found that washing hands with an antibacterial soap was no more effective in preventing infectious illness than plain soap. Moreover, antibacterial soaps at formulations sold to the public do not remove any more bacteria from the hands during washing than plain soaps. Because of the way triclosan, the main active ingredient in many antibacterial soaps, reacts in the cells, it may cause some bacteria to become resistant to commonly used drugs such as amoxicillin, the researchers say. These changes have not been detected at the population level, but e-coli bacteria bugs adapted in lab experiments showed resistance when exposed to as much as 0.1 percent weight/volume triclosan soap. “What we are saying is that these e-coli could […]

(Beyond Pesticides, October 18, 2007) In a scholarly review written by Theo Colborn, Ph.D. and Lynn Carroll, Ph.D., the authors point to the multigenerational effects of some pesticides that they say demand improved regulation to protect human and environmental health. The review, “Pesticides, Sexual Development, Reproduction, and Fertility: Current Perspective and Future Direction,” appears in the international journal Human and Ecological Risk Assessment (13:5, 1078 — 1110), September, 2007. The study points out a major deficiency in the U.S. Environmental Protection Agency’s regulation of pesticides under current health reviews and risk assessments. The authors call EPA’s pesticide registration system “outmoded” and one that has “almost completely missed the low-dose and endocrine system-mediated effects of pesticides.” The study reviews both epidemiological and laboratory data. In the abstract, the authors state the following: Improvements in chemical analytical technology and non-invasive sampling protocols have made it easier to detect pesticides and their metabolites at very low concentrations in human tissues. Monitoring has revealed that pesticides penetrate both maternal and paternal reproductive tissues and organs, thus providing a pathway for initiating harm to their offspring starting before fertilization throughout gestation and lactation. This article explores the literature that addresses the parental pathway of exposure […]

(Beyond Pesticides, October 16, 2007) Corn, genetically engineered (GE) to tolerate the pesticide Bacillus thuringiensis (Bt), has been found to harm non-target aquatic insects and disrupt the connected food web. A new study by researchers at Indiana University, funded by the National Science Foundation and published in Proceedings of the National Academies of Sciences, suggests that the crop, which has been licensed for use since 1996, poses an unforseen risk to aquatic ecosystems. According to the study, roughly 35 percent of American corn acreage is Bt corn. Pollen and other parts of the plants are travelling much farther than the fields in which they are planted, carrying Bt toxins through watersheds and being consumed by close relatives of the corn’s targeted pests. Caddisflies experience high mortality and stunted growth as a result of exposure. As researcher Todd V. Royer observed, they “are a food resource for higher organisms like amphibians and fish. And, if our goal is to have healthy, functioning ecosystems, we need to protect all the parts. Water resources are something we depend on greatly.” This effect went unnoticed for ten years because the Environmental Protection Agency (EPA), in its registration trials, tested Bt on a crustacean, rather […]

(Beyond Pesticides, October, 10 2007) One of the largest chemical companies in the world, BASF Corporation, announced in a press release October 9, 2007 that it will get serious in its campaign against the use of illegal pesticides. The sale and distribution of unregistered or counterfeit pesticidal products is clearly prohibited under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), resulting in harm to public health and the environment. Several companies have recently been fined by the EPA for selling and distributing unregistered or mislabeled pesticide products (See Daily News Blogs: “EPA Fines Clorox Over Export Labels” and “Target Settles with EPA on Labeling Violations”). BASF sees the problem as adversely affecting its bottom line. BASF Agricultural Products spends over 300 million euros in research and development, especially in the field of crop protection, to develop and launch new products. As a result, the company is on a state of alert to prevent activities which deliberately infringe its existing patents or which are illegal, including product counterfeiting and the sale and distribution of unregistered pesticides. The agricultural products division of BASF said that its worldwide fight against illegal pesticides would involve taking legal action for patent infringement, illegal imports of […]

(Beyond Pesticides, October 9, 2007) Two state agencies and the U.S. EPA are close to completing an investigation of the poisoning of over 100 farmworkers in Nevada two weeks ago. Chloropicrin, an agricultural fumigant, drifted to a worker-occupied field, sending 121 laborers to Saint Lyon Medical Center (SLMC) for treatment on the morning of September 26. Upon arrival, the workers were showing symptoms including difficulty breathing, nausea, watery eyes and sore throat. SLMC Administrator Joan Hall said that only 12 of the 121 people required emergency room care, and most returned to work the same afternoon. Normally, chloropicrin’s off-gas dissipates, but because of a weather inversion the fumigant stayed lower to the ground and drifted more than a half-mile away from its application area to the worker-occupied field. Speaking on behalf of local farming operation Peri & Sons Farms, media contact Tim Cummings said both the Nevada Department of Agriculture and Occupational Safety and Health Administration have concluded their portion of the report, with the remaining piece due from the EPA. Peri & Sons owns both fields, which are located just over a half-mile apart, far enough apart from each other for such applications, according to state regulations and the […]

(Beyond Pesticides, October 4, 2007) On September 28, 2007, the Environmental Protection Agency (EPA) delayed approval of the pesticide methyl iodide, a highly toxic replacement chemical for the ozone-depleting methyl bromide (also called iodomethane), after more than 50 prominent scientists objected that the chemical was too dangerous. The decision surprised environmentalists who assumed the pesticide would most likely be registered despite opposition. According to EPA, it now “will address recent questions prompted by the pending registration of iodomethane.” On September 24, 2007, scientists across the country — including six Nobel prize winners, alarmed by the prospect of registering methyl iodide as a pesticide, issued a letter to EPA Administrator Stephen Johnson urging the Agency not to sanction the broad use of methyl iodide now or at any time. “The gratifying thing is that EPA has been responsive to people who are really concerned about this,” Robert Bergman, a University of California at Berkeley professor who organized the scientists’ letter, told the Associated Press. The letter criticized EPA’s scientific analysis, calling for an independent scientific review of the agency’s assessment. Methyl iodide and methyl bromide are injected into the soil at rates of 100-400 pounds per acre to kill soil-borne pests. […]

(Beyond Pesticides, October 1, 2007) For the second time in ten years, state officials have poured aquatic insecticide and piscicide rotenone into California’s Lake Davis in an effort to control an invasive species of fish, northern pike. Despite the first failure of rotenone to eradicate the pike in 1997, Fish and Game officials felt they had no alternative but to resort to the toxic chemical once more. The invasive pike were first introduced, illegally, into Lake Davis in 1994. Since then, the population has reached uncontrollable proportions, out-competing local trout. The small town of Portola, which uses Lake Davis as its drinking water supply, is largely supported by fishing and tourism, which are boosted by its reputation for producing extremely large trout. Local businesses fear the consequences of the pikes’ destruction of the attraction. Despite its economic concerns, the town did not universally support the first application of rotenone in 1997. Four residents, including the mayor pro tem, were arrested in a mass protest of the application as Fish and Game put thousands of gallons of the chemical in the lake. Within a year, pike reappeared. Ten years and many failed attempted alternatives later, the pike population thrives. Fish and […]

(Beyond Pesticides, September 28, 2007) EPA is due to make a decision on methyl iodide, a highly reactive and carcinogenic chemical, for use in crop production as a soil fumigant. Scientists across the country are alarmed by the prospect of registering methyl iodide as a pesticide, and fifty-four chemists and physicians from across the country issued a letter to EPA Administrator Stephen Johnson Monday urging the Agency not to sanction the broad use of methyl iodide now or at any time.“[W]e are concerned that pregnant women and the fetus, children, the elderly, farm workers, and other people living near application sites would be at serious risk if methyl iodide is permitted for use in agriculture,” said the group in the letter. In the chemical community methyl iodide is a well-known cancer hazard due to its ability to mutate DNA, and the scientists are fearful that methyl iodide’s high volatility and water solubility will expose many people to harm if the chemical is used in agriculture. Methyl iodide and methyl bromide are injected into the soil at rates of 100-400 pounds per acre to kill soil-borne pests. Because of the high application rates and gaseous nature of these chemicals, they drift […]

(Beyond Pesticides, September 20, 20087) A citizens group sued the county and the state of California September 14, 2007 for not allowing adequate public input before using toxic sprays on the Eel River to eradicate invasive weeds. Eureka-based Californians for Alternatives to Toxics (CATs) sued the Humboldt County Agricultural Commissioner (County) and the California Department of Parks and Recreation (DPR) for their decision to use herbicides to kill purple loosestrife plants for as many as 10 years without first consulting with the public. The suit, filed in Humboldt County Superior Court, also faults the agencies for failing to consider safer and more effective methods such as biological weed control programs, already used successfully throughout the country.“The decision to spray was made behind closed doors with the many people who care deeply about the Eel River locked out,” said Patty Clary, speaking for CATs. “State law requires that the public be involved in important environmental decisions and that alternatives be seriously considered – these requirements were not met.” The agencies’ decision to spray the herbicide imazapyr from boats on 200 riverbank sites along 25 miles of the Eel was first sprung on the public on July 10 at an invitation-only meeting […]

(Beyond Pesticides, September 19, 2007) In Vietnam, attempts continue to be made to protect villages from the ongoing threat of Agent Orange, used by American forces to deforest the jungle canopy in the Vietnam War over 30 years ago, according to the New York Times. Reforestation and fencing are being carried out to prevent local animals and residents from being exposed to soil contaminated with 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD), a potent dioxin contaminant of Agent Orange. Phung Tuu Boi, forester and director of the Center for Assistance in Nature Conservation and Community Development in Hanoi, is attempting to reforest thousands of hectares in central Vietnam. However, his main concern is the dioxin that taints the soil and the local residents most at risk since they live off the land. “The local people are poor and uneducated, and they don’t understand. Children come here to play and they collect insects and other things to eat,” said Mr. Boi. TCDD is the most dangerous form of dioxin and the levels found in soil samples from Central Vietnam are more than 200 times the “acceptable” level set by the US EPA. Efforts to educate the residents about the dangers of dioxin are difficult since most […]

(Beyond Pesticides, September 18, 2007) On September 16, 2007, researchers from the National Institute of Environmental Health Sciences presented findings to the European Respiratory Society Annual Congress in Stockholm showing that exposure to several commonly used pesticides increases the risk of asthma in farmers. Pesticide exposure is a “potential risk factor for asthma and respiratory symptoms among farmers,” lead author Dr. Jane A. Hoppin told Reuters Health. “Because grains and animals are more common exposures in agricultural settings, pesticides may be overlooked. Better education and training of farmers and pesticide handlers may help to reduce asthma risk.”The study consisted of 19,704 farmers, 441 of which had asthma. Farmers who have experienced high pesticide exposure were twice as likely to have asthma. Sixteen of the pesticides studied were associated with asthma. Coumaphos, EPTC, lindane, parathion, heptachlor, 2,4,5-TP, DDT, malathion, and phorate had the strongest effect. “This is the first study with sufficient power to evaluate individual pesticides and adult asthma among individuals who routinely apply pesticides,” Dr. Hoppin said. Asthma is a serious chronic disorder of the lungs characterized by recurrent attacks of bronchial constriction, which cause breathlessness, wheezing, and coughing. Asthma is a dangerous, and in some cases life-threatening disease. […]

(Beyond Pesticides, September 17, 2007) Mediterranean fruit flies were discovered last week in Dixon, California, and federal, state, and county agencies rushed to respond with traps, biopesticide treatment, and sterile mates to prevent the insect from infesting local agriculture. A total of eight Medflies have been found so far, and the three-pronged attack started with an effort to monitor the presence of the Medfly. California Department of Food and Agriculture (CDFA) employees have placed 1,700 fruit fly-targeted detection traps in an 81-square-mile grid. Next, residents within 200 meters of the original finding had their yards treated with the organic compound Naturalyte, the active ingredient of which is spinosad, a naturally occurring extract from bacteria. The pesticide, made by Dow, is approved for use on organic crops, yet the vast majority of its ingredients (so-called “inerts”) are not disclosed. As another biological control, more than 3 million sterile male flies were released last Friday in a 12-square-mile area around Dixon. The sterile males will be deployed on a weekly basis to mate with wild females, helping to eradicate the Medfly population. This is the first Medfly case in Solano County, according to county agriculture officials. Agriculture Commissioner Jerry Howard said that […]

(Beyond Pesticides, September 14, 2007) Data collected by the Environmental Protection Agency (EPA) between 2003 and 2006 has found atrazine to exist in Midwest drinking water supplies at high levels. The federal monitoring data, obtained by the National Resources Defense Council (NRDC), shows increased atrazine levels in 94 of 136 water systems tested in Indiana, Ohio, Iowa, Kentucky, Minnesota, and Nebraska. Atrazine, which has been linked to cancer in numerous studies, is a common agricultural herbicide that could see increased use as demand for corn rises due to ethanol production. In 2003, EPA called it “the most heavily used herbicide in the United States.” According to NRDC’s report, EPA’s study found that nearly all 40 monitored watersheds showed levels of atrazine at levels that harm aquatic animals and habitat. Atrazine’s effect on amphibians has been well documented, and similarly serious health effects have been found in larger mammals. Chronically contaminated drinking water puts humans at the risk of exposure to similar long-term health effects. In agricultural areas of the midwest, the risk is especially high. “Kentucky’s waterways are particularly vulnerable to contamination,” said a Western Kentucky University report. “Networks of sinkholes and underground streams allow water and contaminants to flow […]

(Beyond Pesticides, September 12, 2007) Tributyltin (TBT), a cheap, but highly toxic barnacle and algae killer once used on nearly all of the world’s 30,000 commercial ships, will soon be banned once a treaty prohibiting its use is signed by the U.S. The ban on TBT, deemed by the U.S. Environmental Protection Agency (EPA) as the most toxic chemical ever deliberately released into the world’s waters, is endorsed by U.S. and European cruise lines, freighter and container fleets, as well as shipyard and marina operators. The U.S. is expected to sign the treaty in the coming months. The treaty is overseen by the U.N. International Maritime Organization and was completed in October 2001. However, Washington has yet to endorse the treaty. By 2008, neither the ships of ratifying countries nor foreign vessels that enter their waters will be allowed to have TBT on their hulls without a sealant. Ships found in violation will be put on an international blacklist and barred by other ratifying countries. Along with forbidding the use of TBT on the hulls of marine vessels, the treaty also sets up a system for future testing and curbs on other hull biocides worldwide. Researchers have linked TBT to […]

(Beyond Pesticides, September 4, 2007) Scientists identified an important biochemical piece in the passage of malaria from mosquitoes to humans. If this link in the chain can be broken at its source””the mosquito””then the spread of malaria could be stopped without the use of harmful pesticides or costly drugs. “Mosquito Heparan Sulfate and Its Potential Role in Malaria Infection and Transmission,” published in the August 31 issue of the Journal of Biological Chemistry, contains the findings of the interdisciplinary team led by researchers from Rensselaer Polytechnic Institute. The research group found that humans and the mosquitoes that carry the malaria parasite Plasmodium share the same complex carbohydrate, heparan sulfate. In both humans and mosquitoes, heparan sulfate is a receptor for the Plasmodium, binding to the parasite and giving it quick and easy transport through the body. Robert J. Linhardt, Ph.D., professor of Biocatalysis and Metabolic Engineering at Rensselaer, led the team. “The discovery allows us to think differently about preventing the disease. If we can stop heparan sulfate from binding to the parasite in mosquitoes, we will not just be treating the disease, we will be stopping its spread completely,” Dr. Linhardt said. Malaria parasites are specific to their host, […]

(Beyond Pesticides, August 24, 2007) The Wisconsin Natural Resources Defense Board recently passed stricter limits on allowable groundwater levels of alachlor-ESA, the breakdown product of the herbicide alachlor, cutting in half the standard to 20 parts per billion (ppb). The reduction from the previous standard of 40 ppb was prompted by the state Department of Natural Resources (DNR), which has tried to pass a similar measure in recent years, only to be blocked by the Republican-controlled Senate. Officials hope that a Democratic majority will ensure adoption of the new standard. The board voted 7-0 in favor of lowering the allowable groundwater level of alachlor-ESA, after DNR cited studies showing the chemical causes blood problems in rats. Department of Agriculture, Trade & Consumer Protection (DATCP) tests in 2001 showed alachlor-ESA in 28 percent of private wells tested, in spite of its declining use (on less than a quarter of the state’s 100,000 acres of corn). A similar proposal was rejected by the board in 2005, when DNR refused to agree to the Joint Committee for Review of Administrative Rules’ request to allow Monsanto, manufacturer of alachlor, to fund a separate study in addition to the state’s data. Monsanto, as expected, issued […]

(Beyond Pesticides, August 20, 2007) Environmental groups launched a public campaign last Wednesday to urge state officials to stop applying toxic herbicides for vegetation control along state roadways. Members of the Massachusetts Coalition for Pesticide Reduction maintain that herbicides, which the state resumed using in 2003, are harmful to people and the environment. Sylvia Broude, community organizer for Toxics Action Center, said toxic chemicals such as the ones the Highway Department uses can harm more than just the intended target. The chemicals can run off highways, pollute drinking water and eventually lead to health problems in humans, ranging from eye problems and learning disabilities to some forms of cancer, she said. The group is asking the state to use organic herbicides or manual means, such as weed whackers or lawnmowers, which the state used exclusively in the early 2000s. But state officials say affected areas are in small, controlled environments. The Highway Department says that it removes unwanted bushes and weeds manually or mechanically on the vast majority of the 48,200 acres it maintains but needs the herbicides for about 188 acres, less than half of 1 percent of the total. Spokesman John Lamontagne said removing weeds mechanically in some […]

(Beyond Pesticides, August 17, 2007) The widespread presence of pesticides and other agricultural runoff has been confirmed in the world’s largest coral reef system. Degradation of the system threatens not only a natural treasure but also the region’s economy. Australia’s Great Barrier Reef is the subject of a recent report by the Great Barrier Reef Marine Park Authority. Entitled the “Annual Marine Monitoring Report 2006,” the study confirms extensive contamination in eight of the ten major tributaries into the marine park, much of which is fertilizer and pesticide runoff from the area’s farmland. Local environmental groups are calling for government protection of the reef from these pollutants, and tourism interests worry that damage to the reef will reduce the number of visitors to Australia. According to World Wildlife Foundation-Australia program leader Nick Heath, “Reducing pollution load is possible and will help us save the Reef, as well as the 60,000 tourism jobs based around the Reef.” According to the report, “Water quality in the Great Barrier Reef is principally affected by land-based activities in its adjacent catchments, including vegetation modification, grazing, agriculture, urban development, industrial development and aquaculture. Nutrients, sediments and pesticides are the pollutants of most concern for the […]

(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 10, 2007) As the face of agriculture in America changes with rising prevalence of herbicide-tolerant crops, farmers in Mississippi and Arkansas are also facing challenges caused by increased herbicide resistance. A recent press release by the Delta Research and Extension Center (DREC) blames glyphosate-resistant weeds for increased costs in Mississippi, while a leading British researcher will work with the University of Arkansas Cooperative Extension Service to determine the impact that the same weeds will have on farming in Arkansas. According to DREC’s release, a “concern for agricultural production in the Mississippi Delta is the increase of weeds resistant to the herbicide glyphosate . . . DREC rice weed scientist Jason Bond said that both glyphosate-resistant horseweed and volunteer Roundup Ready soybeans have become problem weeds for Mississippi rice production.” Research associate Tom Eubank also said, “Glyphosate-resistant horseweed, ryegrass and pigweed are concerns in Mississippi Delta soybeans.” Meanwhile, Arkansas farmers are noticing a similar trend: the increased use of glyphosate on Monsanto’s “Roundup Ready” crops is leading them to map the future of herbicide-resistant weeds and consider alternative weed management programs. According to the High Plains/Midwest Agricultural Journal, “researchers believe that if pigweed, or Plamer amaranth, can’t be […]

(Beyond Pesticides, August 7, 2007) In a study that examines the influence of age of exposure on the magnitude of the association between DDT and breast cancer risk finds that women who were exposed to DDT before the age of 14 are five times more likely to develop breast cancer later in life. In contrast, the study finds exposure after adolescence does not increase risk. The data used in the study targets the age of a woman in 1945 as an indicator for the youngest possible age for a woman to be exposed to DDT, since DDT was first introduced to the U.S. for mosquito control in 1945. The researchers, from the Center for Research on Women’s and Children’s Health, Public Health Institute at Berkeley, California and the Mount Sinai School of Medicine, analyzed blood that had been collected from women between 1959 and 1967 – years during which the use of DDT was at its highest. “DDT and breast cancer in young women: New data on the significance of age at exposure,” published last week in the online edition of the journal Environmental Health Perspectives, is “the first study specifically designed, a priori, to consider whether age at exposure […]
