(Beyond Pesticides, September 30, 2008) A group of insect-killing sprays known as neonicotinoids that are widely used in UK farming have now been banned in four other European countries because they are thought to be killing bees. Italy has just joined Germany, Slovenia and France in banning the sprays. This week the Italian government issued an immediate suspension of these sprays after they accepted that they are killing bees. Yesterday, the Britain’s Soil Association (SA) wrote to Hilary Benn, the Secretary of State for the Environment, urging him to ban the sprays in the UK with immediate effect. In the letter, SA Policy Director Peter Melchett wrote, “I fear it is typical of the current extraordinarily lax approach to pesticide regulation in the UK that we look like being one of the last of the major farming countries in the EU to wake up to the threat to our honeybees.” He also stated that the UK’s current pesticide regulation “is too dominated by scientists from one side of the debate about pesticide safety, fails to take adequate account of the public interest as against the interest of the chemical industry and some farmers, and fails adequately to apply the precautionary […]

(Beyond Pesticides, September 29, 2008) A new study by Pesticide Action Network North America (PANNA) confirms that school children in Florida continue to breathe air contaminated by hazardous pesticides. Air monitoring near South Woods Elementary School in Hastings detected four agricultural chemicals in the air, often at levels that pose unacceptable risks to children. The report mirrors the results of a similar study released in April 2007, confirming the existence of an ongoing problem of pesticide contamination that is more extensive than previously documented. The new test results show that in October, November and December 2007 the air in Hastings was contaminated with the pesticides endosulfan, diazinon https://www.beyondpesticides.org/gateway/pesticide/diazinon.htm, trifluralin and chlorothalonil. Of these, two are neurotoxins, two are suspected carcinogens, and three are or will soon be banned in Europe. Endosulfan, the pesticide of greatest concern, was found in 87% of the samples, and, on several days, exceeded levels of concern. The air monitoring was conducted by concerned area residents using a “Drift Catcher” device, a simple air sampling system that sucks air into tubes, where the pesticides are absorbed and captured. The tubes are then sent to a laboratory, where the chemicals can be identified and the concentrations measured. […]

(Beyond Pesticides, September 26, 2008) On September 24, the U.S. Ninth Circuit Court of Appeals dismissed Ivory Coast farmworkers’ claims that they were victims of genocide when pesticide exposure made them sterile. The nearly 700 plaintiffs were exposed to the soil fumigant and nematocide 1,2-Dibromo-3-Chloropropane, or DBCP, while working on Dole Food Company farms in Africa. The original First Amended Complaint was filed on April 6, 2007, and despite the latest setback, the Africans’ attorney, Raphael Metzger, said he would pursue a rehearing. Until 1977, DBCP was widely used in U.S. agriculture, when it was banned for all uses except pineapples. In contrast, DBCP was widely used for fruit production in developing countries in to the 1990s in spite of its U.S. regulatory status. “The manufacturers continued making money on [DBCP] by shipping it to Third World countries where farmworkers were given it to use,” Mr. Metzger said. The suit, Abagninin v. Amvac Chemical Co, was filed under the Alien Torts Statute and contended “that such conduct supports claims under the ATS for genocide and crimes against humanity because the conduct was undertaken with knowledge of DBCP’s effects and pursuant to a State or organizational policy.” The court rejected Abagninin’s […]

(Beyond Pesticides, September 25, 2008) Pesticides used as lice treatments can not only have extremely harmful effects on children, they are also not as effective as non- chemical treatments such as utilizing directed hot air, according to researchers. Back-to-school season often coincides with lice outbreaks, and parents should be aware of the risks involved in using lice “shampoos” that contain pesticides and informed of the viability of non-toxic alternatives. Many of the recent headlines regarding lice in schools include reference to “super lice,” which are difficult to eliminate. These lice have developed resistance to the chemicals commonly used to treat them, such as lindane, malathion and permethrin, and therefore these treatments are increasingly ineffective. Insects frequently develop resistance to pesticides, a fact that emphasizes the importance of strategies both in agriculture and public health that focus on preventing pest outbreaks and dealing with outbreaks in ways that will not lead to resistance. One such method for eliminating head lice that will not lead to resistant strains of lice is the use of hot air, which desiccates the insects and eggs, thus killing them. Researchers testing six methods of hot air application found that hot air outperforms insecticidal shampoos in killing […]

(Beyond Pesticides, September 24, 2008) Pesticides used on peach orchards over 50 years ago have been detected in the groundwater of three North Carolina counties. Tests have detected 117 tainted wells in Montgomery, Richmond and Moore counties in the past year, 77 of those at unsafe levels. Public Health officials are scrambling to deliver safe water to those whose wells have been contaminated. However, the number of contaminated wells is forecasted to increase as more residents opt to have their groundwater tested, as the news of tainted wells continues to spread. Many residents are also wondering how they have been impacted as a result of their exposure to the tainted water. Local officials are also worried over how far and wide the contamination has spread. Contamination levels as high as 55 times the federal safe drinking-water standard have been detected. Households where concentrations are highest have been told not to drink or cook with their well water, and limit showers to 10 minutes. Peach orchards now grow on a modest 1,350 acres in North Carolina, but production in 1941 was 12 times greater. The chemicals now detected in groundwater were first used in the 1950s and include ethylene dibromide (EDB) […]

(Beyond Pesticides, September 23, 2008) According to the Minnesota Department of Agriculture’s 2007 Water Quality Monitoring Report, released in August 2008, the endocrine disrupting herbicide atrazine is detected in pristine lakes in northern Minnesota far from the agricultural fields where it is applied. Metolachlor, acetochlor and dimethenamid are also frequent contaminants, according to the statewide sampling. The report, which uses data collected by a collaborative program between the U.S. Environmental Protection Agency, the Minnesota Department of Agriculture and the Minnesota Pollution Control Agency, analyzed samples from 55 of the state’s lakes. Atrazine was detected in approximately 87% of the 2007 samples, an increase from 2006. The presence of atrazine in such a large percentage of the lakes, many of which are located in non-agricultural areas of northern Minnesota, suggests widespread atmospheric deposition of this chemical (movement through wind and rain). “To some people, it is a bit of a surprise, but the concentrations are low, very low,” Steven Heiskary, a research scientist with the Minnesota Pollution Control Agency (MPCA) told the Star Tribune. Unfortunately, this is not very reassuring, given the fact that many of the developmental impacts linked to atrazine are seen at very low levels, sometimes at just […]

(Beyond Pesticides, September 22, 2008) A study published in the September issue of Environmental Health Perspectives finds that low-dose, short-term exposure to esfenvalerate, a synthetic pyrethroid pesticide, delays the onset of puberty in rats at doses two times lower than U.S. EPA’s stated no observable effect level (NOEL) of 2.0 mg/kg/day. Synthetic pyrethroids are used for everything from lawn care and household insecticides, to mosquito control and agriculture. There are currently 348 pesticide products registered by the U.S. EPA. The researchers conclude: “Although the exact mechanism of action is unknown at this time, we observed the effects at dosage levels below the NOEL established through chronic dietary exposure studies in rats. The U.S. EPA (1998) http://www.epa.gov/fedrgstr/EPA-PEST/1998/April/Day-29/p11372.htm stated that ”˜There is no evidence of additional sensitivity to young rats or rabbits following pre- or postnatal exposure to esfenvalerate.’ The present study shows that immature female rats exposed to 1.0 mg/kg/day are sensitive to this pesticide, as evidenced by their delay in the onset of puberty. Delayed pubertal onset in humans has been associated with low bone mass density (Ho and Kung 2005), and estrogen is necessary for bone mineral acquisition in both girls and boys (Yilmaz et al. 2005). Importantly, a […]

(Beyond Pesticides, September 19, 2008) Adding to the body of epidemiologic evidence linking pesticides to Parkinson’s Disease (PD), a recent study shows a correlation between 100 PD patients and the use of the pesticide rotenone. The study was conducted by physicians and researchers at The University of Texas Health Science Center at Tyler (UTHSCT) and an East Texas Medical Center physician.The study’s lead author is Aman Dhillon, MD, MS, assistant professor of occupational and environmental medicine at UTHSCT. Rotenone is highly toxic to fish and insects, but mildly toxic to warm-blooded animals and humans. It is made from the roots of tropical plants and is used in home gardens and in fisheries management to remove unwanted fish species, said Jeffrey Levin, MD, MSPH, chair of UTHSCT’s Department of Occupational Health Sciences. Dr. Levin is a co-author of the study, published recently in the peer-reviewed Journal of Agromedicine. A total of 184 people participated in the study: 100 had Parkinson’s disease and 84 did not, though they had other neurological disorders. All were patients of George M. Plotkin, MD, Ph.D., a neurologist with a special interest in Parkinson’s disease. Dr. Plotkin, medical director of the ETMC Movement Disorder Center, treats about […]

(Beyond Pesticides, September 18, 2008) New research in the forthcoming issue of Biological Conservation reveals that roadsides maintained “conventionally” with the use of herbicides, non-native fast-growing grasses and frequent mowing support less native bee diversity and abundance than roadsides restored with native plants. Focus on the importance of native bees has increased in light of the recent honeybee crisis. Roadsides restored to native plants could serve as valuable protective corridors of native pollinators, which are threatened by pesticide use and habitat fragmentation. Jennifer Hopwood, PhD, the author of “The contribution of roadside grassland restorations to native bee conservation,” performed the research in Kansas, where a very small amount of unplowed prairie remains. The intensification and spread of agriculture has reduced the availability of suitable nesting sites, particularly for ground-nesting bees, and has limited food sources as a result of reduced floral diversity. Dr. Hopwood found more than twice the bee abundance in roadsides with native plants and increased bee diversity. The restored roadsides have 79 species of bees, whereas the conventionally managed roadsides only have 53. Roadsides in Kansas account for more than 650,000 acres of continuous corridors, which, if restored to native plants, could add significantly to viable bee […]

(Beyond Pesticides, September 17, 2008) A new study has found a link between total chemical contamination in the bodies of pregnant women and the risk of cryptorchidism in their male babies. Mothers whose babies were born with the defect had the highest concentrations of persistent organic pollutants (POPs), mostly organochlorines like PCB and DDE, in their breast milk. The study, entiltled “Cryptorchidism at birth in Nice area (France) is associated with higher prenatal exposure to PCBs and DDE, as assessed by colostrum concentrations,” and published in the journal Human Reproduction, compared prebirth exposure to chemicals, as measured through their mother’s milk, and the risk of undescended testicles or cryptorchidism, during a three-year period. 164 mother/infant pairs were used and within 3-5 days of delivery, the researchers collected samples of colostrums, or “first milk” from the mother. Colostrum is a form of breast milk that is produced late in pregnancy and immediately after birth before the more creamy milk comes in. It is used as a proxy for what was circulating in the mother’s body and in her fetus during pregnancy. The colostrum was analyzed for three different chemical pollutants including seven polychlorinated biphenyls (PCBs), dichloro-diphenyl-trichloro-ethylene (DDE) and dibutyl phthalate (DBP). […]

(Beyond Pesticides, September 16, 2008) Responding to grassroots pressure highlighting the impact of pests and pesticides on public health, the Boston Public Housing Authority (BHA) is promoting integrated pest management (IPM) through its Healthy Pest Free Housing Initiative Project (HPFHI) in the city’s public housing facilities. The program, which was launched after the Committee for Boston Public Housing, a tenant rights group, began looking into the connection between respiratory health, asthma and housing conditions in 1995, is now proving successful. “The project’s goal is to provide intensive in-home and community-based education designed to change individual and community practices regarding pest control and the use of pesticides,” explains John Kane, IPM coordinator and planner for the Boston Housing Authority (BHA). Mr. Kane says that there has been up to a 75 percent reduction in work orders dealing with pests and a huge increase in the quality of life for the residents. Over 1,000 BHA households in eight developments have received in-home and community-based support and education to encourage integrated pest management practices that focus on prevention and use “least toxic” pesticides only as a last resort. BHA hopes to make the project sustainable and expand their efforts into additional developments. “People […]

(Beyond Pesticides, September 15, 2008) One year after the USDA’s new regulation requiring raw almonds be treated with propylene oxide, a toxic fumigant recognized as a carcinogen by the U.S. EPA, went into effect, a group of fifteen American almond growers and wholesale nut handlers filed a lawsuit in the Washington, D.C. federal court on September 9th seeking to repeal the controversial USDA-mandated treatment program for California-grown raw almonds. The almond farmers and handlers contend that their businesses have been seriously damaged and their futures jeopardized by the requirement that raw almonds be treated with propylene oxide or steam-heated before they can be sold to American consumers. Foreign-grown almonds are exempt from treatment. They hope for a favorable decision in time to protect this year’s almond harvest. “The USDA’s raw almond treatment mandate has been economically devastating to many family-scale and organic almond farmers in California,” said Will Fantle, the research director for the Wisconsin-based Cornucopia Institute. Cornucopia has been working with almond farmers and handlers to address the negative impacts of the USDA rule, including the loss of markets to foreign nuts. They also contend that the USDA requirement lacks scientific justification, does not address the unsustainable methods used […]

(Beyond Pesticides, September 12, 2008) Widespread use of nanoscale silver will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, highlighting the need to identify research priorities concerning this emerging technology, according to a new report released this week by the Project on Emerging Nanotechnologies (PEN). However, existing information about the impact of silver on the environment offers a starting point for some assessments of nanosilver, the report argues. The issue of assessing the risks posed by nanoscale silver was highlighted after the Environmental Protection Agency’s (EPA) San Francisco office earlier this year imposed a landmark fine of over $200,000 on a California company selling computer keyboards and mouses coated with nanosilver. EPA issued the fine on the grounds that the products should have been registered under federal pesticide law because of the company’s germ-killing claims. In May, a coalition of groups also petitioned that EPA regulate nano products as pesticides. Similar fines have not been imposed since, but the action is increasing attention on the potential risks posed by nanoscale silver and oversight of nanotechnology as a whole. There currently are more than 200 manufacturer-identified nanosilver products on the market and contained in […]

(Beyond Pesticides, September 11, 2008) The North Carolina Pesticide Board has begun hearing evidence in a case from 2004 over suspected pesticide violations that were investigated after three female Ag-Mart farmworkers gave birth to babies with severe birth defects. In 2006, the family of Carlos Herrera Candelario, who was born without arms or legs, sued Ag-Mart over illegal pesticide exposure resulting in the boy’s birth defects. The case was settled out of court, with Ag-Mart agreeing to pay the medical expenses of the boy for life and provide him with a permanent income, but insisting that the settlement was not an admission of guilt. The current hearing will look at whether Ag-Mart’s farm manager, Jeff Oxley, is indeed guilty of over 200 violations, including forcing workers into the field too soon after dangerous pesticides were applied. The hearing is significant because the company insists that adequate practices are and have been in place to ensure workers are not exposed to pesticides, even though the testimony of Ag-Mart employees runs counter to this claim. This hearing could do a great deal to elucidate the truth about farmworker pesticide exposure, an important issue for the thousands of workers who plant and harvest […]

(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, September 9, 2008) The U.S. Senate is proposing to cut $2 million per year from the Organic Agriculture Research and Extension Initiative (OREI), the U.S. Department of Agriculture’s premier organic research program, and the Bush Administration is threatening to cut a whopping $8 million, according to the Organic Farming Research Foundation. The move comes after months of grassroots pressure recently delivered a much-needed fivefold increase in mandatory OREI funding, from $15 to $78 million over the next five years, in the 2008 Farm Bill. Beyond Pesticides has long supported organic methods as the solution to pesticide pollution, with organic agriculture being the centerpiece of the conversion necessary to protect human health and the environment, including slowing global warming. Data shows that organic agriculture sequesters atmospheric carbon while chemical-intensive practices are a major contributor to carbon loading. In addition, the reduced pressure on global warming associated with organic agriculture occurs through the drastic reduction in fossil fuel usage (approximately 75% less than conventional agriculture) as well as the significant increase in carbon sequestration in the soil (approximately 1000 lbs. of carbon per acre). See Beyond Pesticides’ organic page. Let the Appropriations Committees Congress know that it is essential to […]

(Beyond Pesticides, September 8, 2008) Inorganic arsenic may increase the risk of developing type 2 diabetes, according to a study published in the Journal of the American Medical Association by researchers at the Johns Hopkins Bloomberg School of Public Health. Common sources of inorganic arsenic exposure include dietary exposure, drinking water pollution, and contamination associated with arsenic wood preservatives such as sawdust, smoke, direct contact, and hazardous waste sites. The study found that individuals with diabetes have higher levels of arsenic in the urine compared to individuals without diabetes. Researchers examined randomly selected urine samples taken from 788 U.S. adults 20 years or older that participated in a 2003-2004 National Health and Nutrition Examination Survey. The results were adjusted for diabetes risk factors, including body mass index and for organic arsenic compounds found in seafood. “Our findings suggest that low levels of exposure to inorganic arsenic may play a role in diabetes,” said Ana Navas-Acien, MD, PhD, lead author of the study and assistant professor with the Bloomberg School’s Department of Environmental Health Sciences. “While prospective studies are needed to establish whether this association is causal, these findings add to the existing concerns about the long-term health consequences of low […]

(Beyond Pesticides, September 5, 2008) On the night of August 28, a pesticide waste tank exploded at Bayer’s Institute, West Virginia plant. One worker was killed, another injured, and the blast was heard in Mink Shoals, more than ten miles away. Despite individual accounts of the resulting air pollution, Bayer officials assured the public that no chemicals had escaped the plant. An investigation of Bayer’s safety history and the area’s emergency response reveals a shaky safety record.. The tank involved in the explosion contained waste products from the production of Bayer’s insecticide, thiodicarb, which is banned in the European Union. Included in those were methyl isobutyl ketone (MIBK), hexane, methomyl, and dimethyl disulfide, all of which are acutely toxic to humans. According to chief of homeland security and emergency response for the state Department of Environmental Protection, Mike Dorsey, “The thing that blew up was the least dangerous of the stuff that’s there.” Jeannie Young, who lives near the plant, said that following the blast, “My daughter and I have headaches.” When taking her dogs outside half an hour following the explosion, “They acted really funny. They wanted to come right back in the house.” In spite of a noticeable […]

(Beyond Pesticides, September 4, 2008) On September 2, 2008, the U.S. Court of Appeals for the Ninth Circuit upheld a nationwide ban on the planting of genetically-engineered (GE) Roundup Ready alfalfa pending a full Environmental Impact Statement (EIS). The Court determined that the planting of genetically modified alfalfa can result in potentially irreversible harm to organic and conventional varieties of crops, damage to the environment, and economic harm to farmers. Beyond Pesticides is a co-plaintiff in the lawsuit. Although the suit (Geertson Seed Farms, et al. v. Johanns) was brought against U.S. Department of Agriculture (USDA), Forage Genetics and Monsanto entered into the suit as Defendant-Intervenors. In her opinion, Circuit Judge Mary M. Schroeder held that, “Monsanto and Forage Genetics contend that the District Court disregarded their financial losses, but the district court considered those economic losses and simply concluded that the harm to growers and consumers who wanted non-genetically engineered alfalfa outweighed the financial hardships to Monsanto and Forage Genetics and their growers.” “This ruling affirms a major victory for consumers, ranchers, organic farmers, and most conventional farmers across the country,” said Andrew Kimbrell, executive director of the Center for Food Safety, lead plaintiff and counsel in the lawsuit. […]

(Beyond Pesticides, September 3, 2008) On September 1, new rules that set harmonized maximum reside levels (MRLs) for pesticides went into force in the European Union (EU), despite opposition from environmental groups that claim the new rules expose consumers to unacceptable levels of contamination. This new regulation, Regulation (EC) No 396/2005, is the result of a considerable joint effort by the European Commission, the European Food Safety Authority (EFSA) and the Member States, and aims to revise and simplify standards pertaining to pesticide residues and, according to officials, helps to strengthen food safety across Europe. The new MRLs aim to remove the confusion associated with dealing with 27 lists of national MRLs. Previously, different MRLs could apply to the same pesticide for the same crop in different member states, which led to confusion, especially in cases where food residues exceeding defined MRLs in one member state were acceptable in another. Traders of produce will now be able to do business smoothly as the confusion surrounding various MRLs is eliminated. The regulation covers approximately 1100 pesticides and lists MRLs for about 315 agricultural products. The MRLs also apply to processed products. “The new rules apply the principle that food produced or […]

(Beyond Pesticides, September 2, 2008) In new research findings by a Pennsylvania State University team, honey bees are exposed to a wide variety of pesticides outside of their hives. Add the outside assault to the pesticides already in the waxy structure of the hive, and bee researchers see a problem difficult to evaluate. However, an innovative approach may mitigate at least some beeswax contamination. The researchers presented their analysis of pollen, brood, adult bees and wax samples on August 18 at the 236th national American Chemical Society meeting in Philadelphia. Those results show unprecedented levels of fluvalinate and coumaphos – pesticides used in the hives to combat varroa mites – in all comb and foundation wax samples. They also find lower levels of 70 other pesticides and metabolites of those pesticides in pollen and bees. “Everyone figured that the acaricides (anti-varroa mite chemicals) would be present in the wax because the wax is reprocessed to form the structure of the hives,” says Maryann Frazier, senior extension associate. “It was a bit of a shock to see the levels and the widespread presence of these pesticides.” While the researchers expected the presence of the chemicals available to treat varroa mites in […]
