California Community Members Contaminated With Pesticides

(Beyond Pesticides, May 17, 2007) Initial results of a pilot program conducted in a Central Valley farming community in California finds that residents have significant levels of the organophosphate chlorpyrifos in their bodies during the spraying season. The levels topped what the U.S. Environmental Protection Agency (EPA) considers acceptable for pregnant and nursing women. Over 91% of the people tested had above average levels of breakdown products of the insecticide chlorpyrifos in their urine, and all but one had chlorpyrifos concentrations above EPA’s recommended threshold of 1.5 parts per billion. The study is an outcome of the collaboration between Pesticide Action Network, Californians for Pesticide Reform, the nonprofit environmental research firm Commonweal, and the community group El Quinto Sol de America. The groups tested the urine of 12 adults in various locations throughout the town of Lindsay during peak spraying season last summer. The results are paired with air monitoring data, also done by the group, that show for three years running chlorpyrifos has not only been detected in the air in town and near schools, but also exceeded EPA’s acceptable level for short-term exposure. The results for the first time shed light on a problem residents suspected but could […]

Following the GE Crop Debate

(Beyond Pesticides, May 1, 2007) More than a month after ordering a temporary halt to sales of genetically engineered (GE) alfalfa seeds, federal district court judge Charles Breyer is considering making the ban permanent, at least until the U. S. Department of Agriculture (USDA) completes a full Environmental Impact Statement (EIS) that confirms the seeds’ safety. (See Daily News of March 14 for Judge Breyer’s reasoning for siding against Monsanto’s team of lawyers, who were arguing that an EIS is unnecessary.) On why he was reluctant to reauthorize the planting of the GE crop, Breyer said, “It is not the court’s function to do an environmental impact study. That hasn’t been done, and I don’t know if the court ought to do it. The government ought to do it, and that is what I held.” Arguments by industry lawyers emphasized their belief that there is very little likelihood of damage being done by the GE alfalfa. Monsanto, which developed the seeds marketed as “Roundup Ready,” argued that there is an “extremely low risk” of conventional crops being contaminated, providing “appropriate stewardship measures” are taken. Monsanto Lawyer Janice Schneider even said, “There are some significant environmental and beneficial effects in Roundup […]

Amvac Corporation Charts Risky Business Model

(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 […]

On Africa Malaria Day, Groups Say No to DDT and Advocate Safe Methods

(Beyond Pesticides, April 25, 2007) Public health and environmental activists call on the world community today to respect life, protect children, stop hazardous pesticide use, including DDT, and adopt what they call “sustainable programs that attack poverty and the conditions that give rise to insect-borne diseases such as malaria.” Africa Malaria Day is commemorated on April 25, a day set aside by African governments committed to rolling back malaria and meeting the United Nations malaria-related Millennium Development Goals. Last September, the World Health Organization came under heavy criticism from public health and environmental groups when it announced its new policy to promote the use of DDT for malaria control in developing countries. Environmental and public health advocates warn that good intentions are in this case misguided. According to the Washington, DC-based non-profit organization Beyond Pesticides, advocating a reliance on pesticides, especially DDT, as a silver bullet solution for malaria protection is extremely dangerous. When the underlying causes of pest problems are not adequately addressed, then a sustained dependence on toxic pesticides like DDT causes greater long-term problems than those that are being addressed in the short-term. “The WHO is misleading the world on DDT, which is a known cancer causing […]

Studies Strengthen Link Between Pesticides and Parkinson’s

(Beyond Pesticides, April 24, 2007) Three recent studies were presented earlier this month at the Parkinson’s Disease Environmental Research meeting in California strengthening the theory that pesticides increase risk of the disease. The studies clarify how pesticide exposure can lead to the development of Parkinson’s. Two pesticides named in the studies are paraquat and dieldrin, both of which have been linked to Parkinson’s in the past. The three new studies, however, combine information from human and animal studies to show how exposure can lead to onset of the disease. As William Langston, M.D., founder of the Parkinson’s Institute, told Reuters, “All of these pieces really look like they are coming together now.” The first study examined a cohort of 80,000 licensed private pesticide applicators and spouses. Researchers found farm workers exposed to paraquat had twice the expected risk of Parkinson’s. The second and third studies address a protein called alpha-synuclein. The second study shows the protein builds up in rodents exposed to paraquat. The third study connects this protein to Parkinson’s by finding that the protein kills the dopamine-producing brain cells affected by the disease. One common difficulty in tracking pesticide-induced diseases is the amount of time that passes between […]

Groups Reject Flawed Nanotechnology Risk Assessment Framework

(Beyond Pesticides, April 13, 2007) A broad coalition of public interest, non-profit and labor groups, including Beyond Pesticides, have issued a letter calling the international nanotechnology community to join them in rejecting a voluntary risk assessment framework. The framework, developed under the leadership of industry in conjunction with the Environmental Defense Fund, is billed as flawed and as a public relations campaign. Nanotechnology, or nanotech, describes the design, production, and application of engineered nano-sized materials from known chemicals such as silver, carbon, iron, or titanium. A nanometer is one billionth of a meter, or around one ten-thousandth the diameter of a human hair. Concern over nanotech products comes from the fact that despite nano-sized chemicals have different properties compared with their bulk-sized counterparts, they are not being adequately regulated and may potentially pose health and environmental risks that are not being properly assessed. The letter states: We, the undersigned, submit this open letter to the international nanotechnology community at large. We are a coalition of public interest, non-profit and labor organizations that actively work on nanotechnology issues, including workplace safety, consumer health, environmental welfare, and broader societal impacts. DuPont Chemical Company (DuPont) and Environmental Defense (ED) jointly have proposed a […]

Companies Face Shareholder Resolutions on Chemical Risks in Products

(Beyond Pesticides, April 5, 2007) In the wake of costly litigation, product sales bans, and reputation damage arising from asbestos, pesticides and other toxic materials in cosmetics and toys, and Teflon-related chemicals, U.S. investors are becoming increasingly wary of toxic chemical risks in products, in supply chains, and in their own portfolios. The number of shareholder resolutions dealing with toxic product risks jumped from three in 2004-2005 to 17 in 2006-2007, including 13 resolutions introduced for the 2007 proxy season at such leading U.S. corporations as Dow and DuPont, according to a press release. In response, the Investor Environmental Health Network (IEHN), which represents 20 investment organizations with $22 billion in assets under management, yesterday released the 52-page “Fiduciary Guide to Toxic Chemical Risk.” The guide for institutional investors examines the financial dimensions of toxic chemical risk, including how to quantify such risk, the theory behind the danger posed by toxic chemicals to the wealth of shareholders, and a comprehensive set of action steps that can be taken by investors to translate the long-term threats and opportunities associated with toxic chemical issues into prudent portfolio stewardship. The IEHN primer for institutional investors concludes: “Researchers are increasingly detecting scores of these […]

Suffolk County Passes Controversial Mosquito Plan, Officials Resign

(Beyond Pesticides, April 2, 2007) The Suffolk County Legislature approved a controversial mosquito control plan, 13-3, despite major objections from other county agencies, environmentalists, and members of Suffolk’s Council on Environmental Quality (CEQ). The eleven-member CEQ advises lawmakers on the environmental impact of proposed county projects and while their recommendations are non-binding, the Legislature has generally followed the group’s advice. Several members of CEQ resigned after the bill’s passage. CEQ objects to the planned use of methoprene, an insecticide that interferes with larval growth. Objections were also raised over the county’s mosquito-control strategy of “ditching,” or altering wetlands to make artificial ponds where mosquito-eating fish thrive, a method they claim is unproven and harmful to the environment. Those objections, which CEQ passed in a split vote earlier this year, were ignored in the final approved plan. Members of CEQ also suggest that in the absence of pathogens like West Nile virus, the threshold for troublesome yet basically harmless mosquitoes should be raised. Prior to the controversial vote by the County Legislature, towns within Suffolk County also opposed the methods. The East Hampton Town Board and town trustees passed resolutions urging the county to abstain from using methoprene. Southampton’s trustees urged […]

New Pesticides Added to Toxic Trade List

(Beyond Pesticides, March 30, 2007) A committee of experts advising the United Nations Environment Programme and the Food and Agriculture Organization (FAO) has recommended adding endosulfan and tributyl tin compounds (TBT) to a list of substances that are considered so harmful they can only be traded in special circumstances. On March 27, 2007, the United Nations said that the toxic chemicals would only be allowed to be exported to countries that have explicitly chosen to permit them, a measure aimed at protecting humans and the environment in developing countries. Endosulfan, a chemical sprayed onto food crops and cotton, and TBT, used in “antifouling paint” for ships’ hulls, are already banned in many countries. However, they may be traded freely in countries lacking tight environmental regulations. According to David Santillo who works at the research center for Greenpeace at Britain’s Exeter University, “It’s great that these two have been added to the list so countries have the choice whether to import them or not.” Endosulfan has been linked with testicular cancer, prostate cancer, breast cancer, and defects in male sex organs. According to a recent study conducted in Costa Rica’s mountain forests, findings show that surprisingly high concentrations of pesticides are […]

Scientist Examines Global Warming’s Impact on Pollen Allergies

(Beyond Pesticides, March 29, 2007) While it seems to allergy-sufferers that symptoms get worse year after year, most figure it’s all in our heads. However, research by Lewis Ziska, Ph.D., a plant physiologist with the USDA Agricultural Research Service’s Crop Systems and Global Change Lab and speaker at the upcoming National Pesticide Forum, shows that common pollen allergens – including the troublesome ragweed pollen – may be getting worse as a result of global climate change. The conventional response to unwanted plants is increased pesticide use, which raises concerns among environmental and public health advocates. According to Dr. Ziska’s research, elevated levels of carbon dioxide (CO2), the top greenhouse gas, and warmer temperatures appear to increase ragweed pollen production. Dr. Ziska’s research uses sealed growth chamber systems to simulate current levels of CO2 (370 parts per million by volume, ppmv) and that projected for the mid-21st century (600 ppmv). The ragweed increased pollen productivity by 131 and 3200% respectively, compared to ragweed grown at pre-industrial CO2 levels (280 ppmv). A recent two-year real-world observational study of ragweed also found that urbanization-induced increases in CO2 and temperature were associated with increased ragweed growth, pollen production and pollen allergenicity, suggesting a probable […]

Industry Group Forms To Generate “Inerts” Data for EPA

(Beyond Pesticides, March 15, 2007) In a press release last week, industry group CropLife America (CLA) announced the formation of its Joint Inerts Task Force (JITF), along with another industry leader, the Chemical Producers and Distributors Association (CPDA). JITF’s creation comes in response to the Environmental Protection Agency’s (EPA) announcement that certain pesticide “inert” ingredients will be subject to regulatory action. EPA’s final rule, published in the Federal Register (71 FR 45415), states, “EPA is revoking 130 inert ingredient tolerance exemptions because insufficient data are available to the agency to make the safety determination required by FFDCA [Federal Food, Drug, and Cosmetic Act] section 408(c)(2).” The rule is slated to go into full effect August 9, 2008. JITF is designed to respond to data gaps that might result in the revocation of some or all of those 130 inert ingredients. JITF currently consists of 29 companies, not necessarily all of which are members of CLA or CPDA, but all of which must prove that they are registrants or inert ingredient suppliers. Information on JITF’s work available to interested parties outside of these qualifications is extremely limited. As Ray McAllister, CLA regulatory and policy leader said in a recent press release, […]

NRDC Sues EPA for Failing To Ban Two Highly Toxic Pesticides

(Beyond Pesticides, March 5, 2007) The Environmental Protection Agency (EPA) has failed to protect the public from exposure to two highly toxic pesticides, dichlorvos (DDVP) and carbaryl. The chemicals are found in common household products that have been demonstrated in laboratory studies to cause severe neurological and developmental harm, according to a lawsuit filed February 28, 2007, by the Natural Resources Defense Council (NRDC). The action charges that EPA has missed its congressionally mandated deadline to finalize a comprehensive reevaluation of carbaryl, failed for 20 years to finish an expedited review of DDVP, and failed to respond to a petition calling for a ban on the chemicals. “EPA is needlessly jeopardizing the health of our children,” said Jennifer Sass, Ph.D., an NRDC senior scientist. “The agency should ban DDVP and carbaryl. There are safer alternatives on the market today, and we urge consumers to avoid any products that use either of these two pesticides.” DDVP*, currently used in pest strips, aerosol sprays and pet collars, is one of a class of the most dangerous pesticides on the market, called organophosphates, which derive from World War II-era nerve agents. Studies have shown DDVP causes cancer in laboratory animals. California lists DDVP […]

USDA Finds Pesticide Residues in Majority of Foods

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

Honeybees Vanish, Threatening Crops and Livelihoods

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

Fracking Biocides Pose Danger to West

(Beyond Pesticides, February 20, 2007) With little oversight from the federal government, a myriad of chemicals are being injected underground in the name of energy exploration in the West. Among these chemicals, biocides are considered to pose a serious threat to environmental and public health. Hydraulic fracturing, known as “fracking” or “frac’ing” for short, is the process approximately 90 percent of oil and gas wells in the U.S. undergo to facilitate extraction. Biocides are used to kill microorganisms that can interfere with other fluids and methods used to stimulate extraction, and to prevent corrosion to pipes. Thousands of wells are popping up over Wyoming, Montana, Colorado, and New Mexico, many of which are located on private property, and some directly adjacent to homes. Many property owners do not own adequate mineral rights to what lies under their land and are rendered powerless to stop energy exploration. With minimal federal oversight, wells, roads and pipelines are established rapidly in these areas bringing heavy traffic, noisy equipment, and air, soil and water pollution. In 2005, the oil and gas industry was granted an exemption from the Safe Drinking Water Act, allowing the injection of toxic fluids directly into groundwater without oversight by […]

Federal Judge Rules USDA Violated Law Regarding GE Seeds

(Beyond Pesticides, February 15, 2007) On February 13, a U.S. District judge ruled that the United States Department of Agriculture (USDA) violated federal environmental law by failing to conduct an environmental impact statement (EIS) on genetically engineered (GE) alfalfa seeds before deregulating them in 2005. Ruling on a lawsuit brought by environmental and farming groups, including Beyond Pesticides, Sierra Club and Center for Food Safety, Judge Charles R. Breyer found that USDA did not adequately defend its decision to forgo an EIS, while validating a number of the plaintiffs’ arguments. Alfalfa is the U.S.’s fourth-largest crop, and third most valuable. GE alfalfa seeds, primarily marketed by Monsanto as Roundup Ready, are engineered with a gene that causes them to be resistant to glyphosate. Among the plaintiffs’ concerns are contamination and cross-pollination between GE and natural crops, which can occur at a distance of up to two miles. Judge Beyer wrote, “Such gene transmission is especially likely in this context given the geographic concentration of alfalfa seed production.” He continued, “For those farmers who choose to grow non-genetically engineered alfalfa, the possibility that their crops will be infected with the engineered gene is tantamount to the elimination of all alfalfa; they […]

Action Alert: Inventor of Toxic Herbicide To Be Honored

(Beyond Pesticides, February 12, 2007) John E. Franz, Ph.D., inventor of the toxic herbicide Roundup (active ingredient is glyphosate), is to be inducted in the National Inventors Hall of Fame, along with inventors of the MRI, the automotive airbag, vaccines, and various medicines. The honor is being awarded under the false claim that glyphosate is nontoxic. The 2007 class of inductees was announced at an event Thursday, February 8, on Capitol Hill, and the induction ceremony will take place on May 5 in Ohio. The statement released by the National Inventors Hall of Fame says of Dr. Franz: “In 1970, while working at Monsanto, Franz discovered the glyphosate class of herbicides, later marketed under the brand name Roundup ®. Glyphosate herbicides eliminate more than 125 kinds of weeds and are nontoxic to animals.” In fact, Roundup has been found to be harmful to animals and may pose a threat to humans as well. Glyphosate, the active ingredient in Roundup, is the number one most commonly used pesticide in U.S. agriculture, and the second most commonly used in non-agricultural settings in the U.S. According to a Beyond Pesticides literature review (GATEWAY), glyphosate is linked to cancer, reproductive effects, neurotoxicity, kidney/liver damage, […]

Katrina Results in Increased Arsenic Levels

(Beyond Pesticides, February 9, 2007) The effects of Hurricane Katrina are still being felt in the Gulf Coast, a year and a half after it hit. Research shows one of the secondary effects of Katrina is increased arsenic levels, largely due to debris treated with the wood preservative chromated copper arsenate (CCA). The debris, mostly originating from damaged and destroyed residential buildings, total 72 million cubic meters, of which 16% has been estimated to be wood, and all of which must be added to landfills. The resulting risk to groundwater is an estimated 1,740 metric tons of arsenic, much of which has been deposited into unlined landfills. The source of this arsenic is primarily from chemically treated lumber, as chromated copper arsenate (CCA) was once commonly used to pressure-treat wood. The Environmental Protection Agency (EPA) has since banned the use of CCA in residential projects, but many older structures still contain the treated wood. A study, released online in the January 2007 issue of Environmental Science & Technology, led by Helena Solo-Gabriele, Ph.D., of the University of Miami and Brajesh Dubey, Ph.D., of the University of Florida, surveyed debris in New Orleans. Out of 225 pieces of lumber tested in […]

Study Sheds Light on Pesticides’ Link to Parkinson’s Disease

(Beyond Pesticides, February 8, 2007) Investigators at St. Jude Children’s Research Hospital have shed new light on the suspected role of pesticides in the development of Parkinson’s disease (PD). The study, “GST expression mediates dopaminergic neuron sensitivity in experimental parkinsonism” appearing in the Proceedings of the National Academy of Sciences (January 31, 2007), illustrates the mechanism of nerve cell damage by pesticide exposure. The enzyme that prevents damage to the substantia nigra, the part of the brain where nerve cell damage associated with PD occurs, is called GST pi (“pie”). This enzyme stands like a sentry at the crossroads of several biochemical pathways, any one of which can lead to PD. GST pi protects the nerve cell from death caused by either environmental toxics, such as pesticides, or a self-destruction process called apoptosis (cell suicide), triggered by certain stressful conditions in the cell. If GST pi levels are reduced or this enzyme is overwhelmed by toxics, these nerves are at increased risk of death, according to studies in mouse models. GST pi is one of a family of similar enzymes that eliminate free radicals generated by pesticides and other chemicals. Two members of this family are present in the brain, […]

Lawsuit Filed To Speed Phase-Out of Deadly Pesticides

(Beyond Pesticides, February 6, 2007) Conservation groups have challenged a government plan that would allow six more years use of a deadly pesticide it admits needs to be banned. The groups, represented by Earthjustice, have reopened a lawsuit in federal district court aiming at speeding up the removal of azinphos-methyl, commonly called AZM or guthion. The legal actions also takes aim at getting rid of two other deadly pesticides, phosmet and chlorpyrifos. All three pesticides were developed from World War I-era nerve toxins. AZM is used primarily to kill insects on orchard crops such as apples, cherries, pears, peaches, and nectarines. The highest uses occur in Washington, Oregon, California, Michigan, Georgia, New York, New Jersey, and Pennsylvania. Chlorpyrifos is used widely on corn and orchard crops. Use of phosmet on orchard crops and blueberries poses particularly serious risks to workers. In November 2006, EPA decided that AZM poses unreasonable adverse effects and must be banned but allowed its continued use on fruit crops for six more years — until 2012 — and on nut crops for three more years — until 2009. “With safer alternatives already in widespread use, EPA has betrayed the trust of the men, women, and children […]

LA County Fish Remain Highly Contaminated with DDT

(Beyond Pesticides, February 1, 2007) Thirty-five years after the banning of DDT, extremely high concentrations of the pesticide are being found in fish caught in California’s Los Angeles county waters. According to a newly released federal survey by the National Oceanic and Atmospheric Administration (NOAA) and Environmental Protection Agency (EPA), the fish caught in the area contain the world’s highest-known DDT concentrations. The survey was conducted in order to update health advisories on which fish are unsafe to eat and to help EPA decide whether to attempt a costly operation to reduce continued contamination from a deposit of DDT on the ocean floor. The findings contradict the belief held by some scientists that DDT on the ocean floor has been breaking down into less-toxic compounds and would soon disappear from marine life. The contamination, most severe in the middle of San Redondo Bay, stems from a 100-ton deposit of DDT released by the Montrose Chemical Co. beginning in the late 1940s, which still covers several square miles of the ocean floor. The pesticide manufacturer had a plant near Torrance, California, from 1947 to 1971, releasing about 2,000 tons of DDT into county sewers that subsequently emptied into the ocean. The […]

New Jersey Rejects Toxic Sprays for Gypsy Moths

(Beyond Pesticides, January 31, 2007) On January 29, the New Jersey Department of Environmental Protection (DEP) concluded a month-long review of the Department of Agriculture’s (NJDA) petition to waive the state’s ban on aerial-spraying of broad-spectrum pesticides. The state will uphold the ban, effectively blocking widespread use of the chemical Dimilin. The ban affects towns seeking to reduce rising gypsy moth populations. Roughly 125,000 acres of trees suffered defoliation in the state as a result of gypsy moths, one of the worst years in recent memory. Gypsy moths have been in New Jersey since the 1920s, and their destruction peaking in 1981, with 800,000 acres defoliated. Dimilin is a restricted-use pesticide (available only to certified applicators) that has been unavailable for broadcast use for decades. For the past 20 years, in lieu of aerial spraying of Dimilin — also known as diflubenzuron — the pesticide specified in NJDA’s request, New Jersey towns have used bacillus thuringiensis (Bt) , a bacterial agent. With gypsy moth populations expected to be higher in 2007 than in recent years, NJDA argued that Bt would be insufficient to protect hardwood trees across the state. In a letter to NJDA, Marcedius T. Jameson, DEP’s administrator for […]
