Site Contaminated With Pesticides To Be Cleaned Up

Wednesday, November 21st, 2007

(Beyond Pesticides, November 21, 2007) The US Environmental Protection Agency unveiled its final plan to clean up a former fertilizer and insecticide plant that leaked numerous pesticides from its storage facility in Arvin, California. Among the chemicals released were dinoseb, ethylene dibromide, as well as other fumigants that have since contaminated the soil and potentially the groundwater. Brown and Bryant, the company that manufactured and stored the chemical, was shut down 18 years ago. Since then residents have feared that the chemicals leaked would eventually get to the drinking water. The EPA confirmed that people who accidentally ingest or come into direct contact with contaminated groundwater or soil may be at risk. The plan for the site is three-fold. The first component is to relocate the nearest water well to another location yet to be determined. The second component is to design and implement a system of large water arbor wells to pump and treat contamination in the shallow groundwater that is contained below the site. The third component is to develop a monitored “natural attenuation” plan. This is the natural decomposition process of contaminants in the middle aquifer. Residents were hoping that the plan would also include the removal […]

EPA Expected To Allow Toxic Fumigant for Agriculture

Friday, September 28th, 2007

(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 […]

California Proposes New Fumigant Regulations

Monday, May 21st, 2007

(Beyond Pesticides, May 21, 2007) On Friday, May 18, the California Department of Pesticide Regulation (DPR) proposed rules to sharply reduce fumigant air emissions that contribute to smog. Acting under a federal court order, DPR will begin allocating fumigant use in areas with poor air quality. The proposed rules make California the first state to dictate how and where several widely used fumigants can be applied on fields statewide, said Glenn Brank, spokesman for the state Department of Pesticide Regulation. The directive, which the agency has the authority to set, centers on fumigants – gases fruit and vegetable growers use to kill pests in the soil before planting. The chemicals have long been blamed for being part of the state’s air pollution problem because they cause smog-forming gases when they evaporate from fields. The rules also would eliminate some fumigation methods that permit high emissions of volatile organic compounds (VOCs) into the air. While farm chemicals comprise only about 2 percent of California’s overall VOC emissions, pesticides are among the top ten VOC sources in the San Joaquin Valley and Ventura air attainment areas. The Southeast Desert area also fails to meet pesticide VOC goals. The Department predicts its plan […]

New Study Strengthens Link Between Pesticide Exposure and Lymphoma

Thursday, May 10th, 2007

(Beyond Pesticides, May 10, 2007) The risk of non-Hodgkin’s lymphoma is significantly increased with substantial exposure to pesticides, regardless of asthma or atopy history, according to findings from a study published in the May issue of the International Journal of Cancer. This study further strengthens the link between exposure to pesticides and cancer and specifically to lymphoma. “Occupational exposure to pesticides and a personal history of atopy have been widely examined as risk factors for non-Hodgkin’s lymphoma (NHL), a neoplasm arising from cells of the immune system,” writes Claire M. Vajdic, Ph.D., of the University of New South Wales, Australia, and colleagues. “These studies have typically found that exposure to pesticides increases risk of NHL, while asthma, or atopy more generally, has been inconsistently protective.” In an Australian population-based, case-control study, the researchers examined the interaction between occupational pesticide exposure and atopy on the risk of NHL. Included in the study were 694 incident cases and 694 randomly selected controls that were matched to cases by age, sex, and state of residence. Participants completed telephone-administered job-specific questionnaires. Experts used the information collected to determine occupational pesticide exposure. History of atopy (including asthma, hay fever, eczema, and food allergy) was self-reported. […]

Amvac Corporation Charts Risky Business Model

Friday, April 27th, 2007

(Beyond Pesticides, April 27, 2007) Health risk, environmental risk and investment risk all have one thing in common — they are all part of Amvac Chemical Corporation’s business practices. According to a Los Angeles Times investigation earlier this month, this socially irresponsible business model has led Amvac to double-digit revenue growth and a toxic legacy. The Amvac homepage reads, “The Company’s chief strategy is to acquire niche product lines from multi-billion dollar companies that divest mature products to focus on newly discovered molecules. The Company’s products include insecticides, fungicides, herbicides, soil fumigants, defoliants, molluscides and growth regulators.” In actuality, Amvac buys the rights to older, high risk pesticides from larger companies. Many of these pesticides, which are some of the most toxic on the market, are likely to be banned or restricted due to safety concerns. Amvac hires scientists and lawyers to keep these dangerous chemicals on the market as long as possible. The company also often skirts regulatory issues by exporting products to countries with weaker regulatory systems. “There’s something here rather unique, which is a company that basically goes intentionally after chemicals that are in trouble because of health and safety concerns,” said Steve Schatzow, a former director […]

Agricultural Pesticides May Be Risk Factor for Gestational Diabetes

Monday, March 26th, 2007

(Beyond Pesticides, March 26, 2007) A new study finds exposure of pregnant women to agricultural pesticides during the first trimester may increase the risk of gestational diabetes. The over twofold increase in risk is associated with some of the most commonly used agricultural pesticides. The study, published in the March issue of Diabetes Care, used a study group comprised of wives of licensed pesticide applicators. Self-reported pesticide-related activities during the first trimester of the most recent pregnancy were analyzed for 11,273 women. Of this group, 506 women reported having gestational diabetes. Agricultural pesticide exposure during pregnancy, such as mixing or applying pesticides or repairing pesticide application equipment, resulted in an odds ratio of 2.2 [95% CI 1.5-3.3] for reporting gestational diabetes — in other words, the women were 2.2 times more likely to develop the disease. No association was found between residential pesticide exposure during pregnancy and gestational diabetes, but it should be noted that the study group is not necessarily representative of urban/suburban populations. The increased risk of developing gestational diabetes was associated with the frequent use of 2,4,5-T, 2,4,5-TP, atrazine, butylate, diazinon, phorate and carbofuran. The data for this study was collected through the Agricultural Health Study (AHS), […]

California Pesticide Regulation Budget To Increase

Wednesday, January 17th, 2007

The California Department of Pesticide Regulation (DPR) will be able to step up pesticide regulation this year due to a significant increase in its 2007 budget, resulting in the largest availability of funding in fifteen years and more resources to direct to enforcement and education of pesticide laws. DPR’s 2007 budget grew by $3 million, thanks to a law passed last year allowing the collection of fees from wholesale pesticide sales. DPR’s $69 million budget is fully funded by fees imposed on pesticide sellers and similar funds, rather than the state’s general fund. Until last year’s law included large-scale commercial sellers like Wal-Mart, Costco, and Home Depot, revenues were mostly derived from agricultural sellers. This is DPR’s largest budget since it’s inception in 1991, and is comparable to the inflation-adjusted budget from 2001, before California’s severe budget cuts. Among other specific uses for the new funds will be the hiring of six new enforcement officials, and a four percent increase in enforcement funds to county agricultural commissioners. Grants will be renewed for the first time since 2003, potentially helping growers find alternatives to methyl bromide, an internationally phased-out fumigant of which the United States is annually granted usage by members […]
