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

(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, October 10, 2008) A study published in the American Journal of Epidemiology [Vol. 167, No. 8] finds women who have used herbicides are twice as likely to have meningioma, a specific kind of brain tumor. The study, “Occupational exposure to pesticides and risk of adult brain tumors,” was conducted by the National Cancer Institute. The authors examined the risk of two types of brain cancer, glioma and meningioma, associated with occupational exposure to insecticides and herbicides in a hospital-based, case-control study of brain cancer. Cases were 462 glioma and 195 meningioma patients diagnosed between 1994 and 1998 in three U.S. hospitals. Controls were 765 patients admitted to the same hospitals for nonmalignant conditions. Occupational histories were collected during personal interviews. Exposure to pesticides was estimated by use of a questionnaire, combined with pesticide measurement data abstracted from published sources. The researchers found no overall link between brain cancer and on-the-job exposure to pesticides or herbicides. However, looking closer at the data, the researchers noticed that women who reported using herbicides had a more than doubled risk for meningioma compared with women who never used herbicides, and there were significant trends of increasing risk with increasing years of herbicide […]

(Beyond Pesticides, October 9, 2008) The Center for Food Safety challenged today U.S. Department of Agriculture’s (USDA) new proposed regulations for the oversight of growing genetically engineered (GE) crops, some of which contain insecticides and many of which are herbicide tolerant. It is the Center’s view that while stricter regulation of growing and field testing GE crops is needed, the USDA proposal fails to fully protect the public’s safety or the environment. The Center contends that these proposed regulations may set in motion a process that would put many GE crops completely beyond the bounds of regulation, and outside the safety net designed to protect the American public. Among the many concerns about genetically engineered foods is the impact they may have on insect and weed resistance to pesticides. Crops engineered to contain the soil bacterium Bacillus thuringiensis (Bt) threaten the long-term efficacy of Bt, which is an approved insecticide in organic farming. Crops engineered to be herbicide tolerant, such as Roundup Ready soy, contribute to the increased use of toxic herbicides, leading to resistance. “The USDA has missed a golden opportunity to improve its oversight of genetically engineered crops,” said Bill Freese, Science Policy Analyst for the Center for […]

(Beyond Pesticides, October 8, 2008) In May, the U.S. Department of Agriculture (USDA) abruptly halted its program that tracks pesticide usage in fruits, vegetables and field crops, only to have the U.S. Senate in July put the program back in the 2009 Senate budget bill. USDA cited the $8 million program expense as the reaon for the reports’ demise, however the move left scientists, public advocates and even industry groups surprised and concerned about carrying out their work without this information. The Agricultural Chemical Usage Reports, launched in 1990 and administered by the National Agricultural Statistics Service (NASS), issues pesticide usage data on crops, having been initiated in response to public concerns over the contamination of apples by the pesticide Alar.The information was also widely used by universities and food industry researchers to help farmers monitor and reduce the amount of pesticides they use. “We looked at the budget and said, “We can’t do everything we have been doing, and what are we going to get rid of?” said Mark Miller of NASS. However, a coalition of public interest groups which included Beyond Pesticides, NRDC, the Center for Food Safety, and the Union of Concerned Scientists argued that the Agricultural […]

(Beyond Pesticides, October 7, 2008) After months of grassroots pressure by the Genetic Engineering Policy Project, Center for Food Safety and others, Governor Schwarzenegger signed AB 541, The Food and Farm Protection Act, on September 27, 2008. Under this law, farmers that are unknowingly contaminated by genetically engineered (GE) crops in California are now protected from liability. Monsanto, which has aggressively litigated to protect its seed patents, must now use a protocol to investigate farmers and sample their crops under legal standards that require notification. “We’re pleased to see that this bill will give farmers new protections from legal implications related to GE crops,” said Rebecca Spector, West Coast Director for Center for Food Safety. “While it is a compromise, it’s still an important step in the right direction.” AB 541 protects California farmers who have not been able to prevent the inevitable – the drift of GE pollen or seed onto their land and the subsequent contamination of non-GE crops. Farmers with crops that become contaminated by patented seeds or pollen have been the target of lawsuits brought by biotech patent holders, most notably Monsanto. Further, if their contaminated crops cause harm to other farmers, the environment or consumers, […]

(Beyond Pesticides, October 6, 2008) University of Pittsburgh researchers have found that the commonly used insecticide malathion can decimate tadpole populations by altering their food chain. The study, published in the October 1 edition of Ecological Applications, finds that gradual amounts of malathion that were too small to directly kill developing leopard frog tadpoles instead sparked a biological chain of events that deprived them of their primary food source. As a result, nearly half the tadpoles in the experiment did not reach maturity and would have died in nature. The results build on a nine-year effort to investigate whether there is a link between pesticides and the global decline in amphibians, which are considered an environmental indicator species because of their sensitivity to pollutants. According to the researchers, their deaths may foreshadow the poisoning of other less environmentally-sensitivespecies, including humans. According to the U.S. Environmental Protection Agency (EPA), malathion is the most commonly used insecticide in U.S. agriculture and the third most commonly used insecticide in the U.S. home and garden sector. It has been detected in the wetlands where frogs and other amphibians live. The researchers created simulated ponds from 300-gallon outdoor tanks containing wood frog and leopard frog […]

(Beyond Pesticides, October 3, 2008) Activists and individuals concerned about misleading claims on pesticide labeling scored a victory on Wednesday when the Environmental Protection Agency (EPA) withdrew its draft notice on label statements regarding cause marketing and third-party endorsements. After a two-year process of EPA proposals and public comment periods, the agency has determined that such label statements do nothing to promote “consumer understanding” of the risks and applications of pesticide products, and will not be encouraging further submissions. In its notice, EPA writes, “The Agency agrees that cause marketing claims and third-party endorsements as outlined in the draft PR Notice generally would not contribute meaningfully to improving protection of human health and the environment. The addition of such statements is not likely to enhance users’ ability to understand the labeling required to inform the user about how to use the product safely and effectively. In fact, the addition of such statements could interfere with that goal. In addition, EPA recognizes that its resources are limited and should be targeted towards activities that will enhance the level of protection of human health and environment from pesticides.” In 2006, The Clorox Company submitted an application to EPA to add cause marketing […]

(Beyond Pesticides, October 2, 2008) Beyond Pesticides and the other members of the National Organic Coalition (NOC) recently sent a letter outlining their concerns over the development of “sustainable” agriculture labeling standards, which are currently under discussion and entering the first phase of draft standards-setting, overseen by the Leonardo Academy under the American National Standards Institute (ANSI) guidelines. The coalition, along with many other organic farming advocates, say they cannot support a “sustainable” label because of what appears the inevitability that it will be “less than organic,” thus reversing progress organic agriculture has made in recent decades and “effectively driving markets to lower standards” that do not protect human health and the environment. After a long fought battle by organic advocates to maintain organic integrity under a national standard, organic agriculture has emerged not only as the most stringent standard for ensuring environmental and human health, it has also gained widespread consumer acceptance in the market place. The NOC letter states: “With a sustainable standard, whether intentional or unintentional, consumers will undoubtedly be led to believe that, in supporting the standard, they are contributing to improved practices. In fact, they are slowing the growth of standards [organic] that are critical […]

(Beyond Pesticides, October 1, 2008) Last week, a jury awarded $1 million in compensation to an organic farm in Santa Cruz, California, whose herbs were contaminated by pesticides. The jury found that organophosphate pesticides, used on vegetables on neighboring farms, drifted onto the organic farm, leaving the herbs in violation of organic standards. The organic farm, Jacobs Farm Del Cabo, filed a lawsuit against the pesticide application company Western Farm Service, Inc. in May 2007. The suit sought an order to stop Western Farm Service from spraying pesticides that contaminate crops at Wilder Ranch State Park, where Jacobs Farm leases 120 acres. Compensation for losses, in the sum of $1 million, which resulted from pesticide contamination, was also sought. The court ruled that pesticide applications by Western Farm Service resulted in trespass of the pesticides onto Jacobs Farm and were legally determined to be a nuisance depriving Jacobs Farm of the right to use and enjoy the land, caused by negligence on the part of Western Farm Services. The jury found that Jacobs Farm was damaged in the sum of $1 million and Judge Robert Atack ordered judgment in that amount against Western Farm Service. The organophosphates, chlorpyrifos, diazinon, and […]

(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 […]
