(Beyond Pesticides, March 19, 2009) Researchers investigating the long-term immune effects of dioxin have found that exposure to dioxin during development or while nursing diminishes the capacity to fight infection later in life. The study, published in Toxicological Sciences, reported that mouse pups born to pregnant mice that were exposed to a small amount of dioxins had fewer white blood cells that normally kill the flu virus and more of a different kind that increases lung inflammation. The study entitled, “The aryl hydrocarbon receptor affects distinct tissue compartments during ontogeny of the immune system,” aimed to identify the critical windows of exposure where fetuses are most sensitive to dioxin’s harmful effects. Pregnant mice were given a dose of 1,000 ppt dioxin either during pregnancy, lactation, or throughout pregnancy and lactation. After dosing, mothers and pups were kept dioxin-free. Researchers then infected mothers and pups with a non-lethal dose of the influenza virus. Researchers found that the number of specialized white blood cells – referred to as CD8+ T-cells that specifically recognize and kill the flu virus, were significantly reduced in the pups but not their mothers. The most severe reduction in these white blood cells was seen when dioxin was […]

(Beyond Pesticides, March 16, 2009) Exposure to a mixture of the fungicide maneb and the herbicide paraquat significantly increases the risk of developing Parkinson’s disease, according to a new University of California, Berkeley study, “Parkinson’s Disease and Residential Exposure to Maneb and Paraquat from Agricultural Applications in the Central Valley of California.” Published in the American Journal of Epidemiology, the study findings show that exposure to both pesticides within 500 meters of an individual’s home increases the risk of developing Parkinson’s by 75 percent. For individuals 60 years of age or younger at the time of diagnosis, there is a more than four-fold increase in risk of the disease when exposed to a combination of maneb and paraquat and a more than doubling of risk when exposed to either maneb or paraquat alone. The Berkeley researchers used geographic information systems that analyzed data from California Pesticide Use Reports and land-use maps to calculate historical residential exposure to agricultural exposure to the two pesticides. From 1998 to 2007, the researchers enrolled 368 incident Parkinson’s disease cases and 341 population controls from California’s Central Valley and developed potential exposure estimates incurred between 1974 and 1999. Also published this month by some of […]

(Beyond Pesticides, March 13, 2009) National Women’s History Month (March 2009) features a new film honoring Rachel Carson, the woman who launched the modern environmental movement. The film, A Sense of Wonder, will be screened nationwide to celebrate today’s women leaders who are saving the planet. Beyond Pesticides believes that the film, which is available on DVD, is a great tool for community organizers. March activities include three major city celebrations and film premieres: Washington, DC: Wednesday, March 18, 7:00pm at the National Portrait Gallery. Co-sponsored by the Environmental Film Festival. (8th & F Streets NW, Washington, D.C., 20001) Los Angeles: Thursday, March 19, 7:30pm at the Laemmle Music Hall Theater.

Al […]

(Beyond Pesticides, March 5, 2009) A new study published in the March 2009 issue of Environmental Health Perspectives finds that pesticide combinations cause more harm to endangered salmon than ndividual pesticide exposure. This means that single-pesticide risk assessments required by the Environmental Protection Agency (EPA) inadequately assess hazards. Mixtures of organophosphate and carbamate pesticides are commonly detected in freshwater habitats that support threatened and endangered species of Pacific salmon. According to the researchers from the National Oceanic and Atmospheric Administration (NOAA) Fisheries and Washington State University, these pesticides inhibit the activity of acetylcholinesterase (AChE) and thus have potential to interfere with behaviors that may be essential for salmon survival. The researchers measured brain AChE inhibition in juvenile coho salmon exposed to sublethal concentrations of the organophosphates diazinon, malathion, and chlorpyrifos, as well as the carbamates carbaryl and carbofuran. The pesticides were tested individually and in combination. They plotted AChE levels on a curve to determine whether the toxicologic responses to binary mixtures were additive, antagonistic (lesser than additive) effect, or synergistic (greater than additive). The authors observed addition and synergism, with a greater degree of synergism at higher exposure concentrations. Several combinations of organophosphates were lethal at concentrations that were […]

(Beyond Pesticides, March 4, 2009) The Ontario government is set to announce sweeping new regulations that will prohibit the use of 85 chemical substances, found in roughly 250 lawn and garden products, from use on neighborhood lawns. Once approved, products containing these chemicals would be barred from sale and use for cosmetic purposes. On November 7, 2008, the Ontario government released a proposed new regulation containing the specifics of the Cosmetic Pesticides Ban Act, passed last June. Then, Ontario joined Quebec in restricting the sale and cosmetic use of pesticides but environmental and public health advocates said then that the new law preempted local by-laws and actually weakens protections in some municipalities with stronger local protections. There are over 55 municipalities in Canada where the residential use, but not sale, of pesticides is banned. The prohibition of these 85 substances is the latest step in this Act. The proposal contains: ”¢ List of pesticides (ingredients in pesticide products) to be banned for cosmetic use ”¢ List of pesticide products to be banned for sale ”¢ List of domestic pesticide products to be restricted for sale. Restricted sale products include those with cosmetic and non-cosmetic uses (i.e., a product that’s allowed […]

(Beyond Pesticides, March 3, 2009) National radio commentator, writer and author Jim Hightower will be speaking at the 27th National Pesticide Forum, Bridge to an Organic Future: Opportunities for health and the environment, April 3-4, 2009 in Carrboro, NC. Twice elected Texas Agriculture Commissioner, Mr. Hightower believes that the true political spectrum is not right to left but top to bottom, and he has become a leading national voice for the 80 percent of the public who no longer find themselves within shouting distance of the Washington and Wall Street powers at the top. His talk at the Forum is called, “Putting ‘Progress’ Back In Progressive: The route to social justice, fair food and a sustainable environment.” In his latest book, Swim Against The Current: Even A Dead Fish Can Go With The Flow, America’s most irascible and hilarious curmudgeon turns a kind and benevolent eye toward brave, hardy, and hardworking souls around the country who have found ways to break free from corporate tentacles; redefine success in business, politics, and life in general; and blaze new pathways toward a richer and happier way of life, from the farmers’ cooperative that said “NO!” to Wal-Mart and thrived to the economists […]

(Beyond Pesticides, March 2, 2009) Pesticide exposure and genetic variability in the dopamine transporter (DAT), a protein that plays a central role in dopaminergic neurotransmission of the brain, interact to significantly increase the risk factor for Parkinson’s disease, according to a new study by University of California, Los Angeles (UCLA) researchers. The population based case-control study, “Dopamine Transporter Genetic Variants and Pesticides in Parkinson’s Disease,” builds on the existing body of evidence of animal data and epidemiological studies that link exposure to pesticides, including gene-pesticide interactions, to Parkinson’s disease. The UCLA researchers, looking at incident Parkinson’s disease cases in three rural counties in Central California, find DAT increases the risk of Parkinson’s when individuals have occupational or residential exposure to pesticides. This is the first epidemiologic study of Parkinson’s disease that relies on pesticide data that is from a record-based source versus recall-based data relying on individuals’ memory. The second most common neurodegenerative disease affecting more than one million people in the U.S., Parkinson’s disease occurs when nerve cells in the substantia nigra region of the brain are damaged or destroyed and can no longer produce dopamine, a nerve-signaling molecule that helps control muscle movement. The new UCLA study is […]

(Beyond Pesticides, February 25, 2009) After three years of legal battle, the North Carolina Pesticide Board on February 19, 2009 fined Florida-based Ag-Mart Produce Inc. a substantially lower fine of $3,000 than the originally proposed $185,000, after deciding that it can only prove six of about 200 worker safety accusations that had been levied against the company. This comes less than a month after the unprecedented ruling against Ag-Mart in New Jersey, where the company was ordered to pay penalties of more than $931,000 for misusing pesticides and jeopardizing the health and safety of workers in its New Jersey farm fields and packing houses. The Florida-based company, described as one of the biggest pesticide offenders, has been accused of routinely exposing hundreds of workers to toxic chemicals. Investigators in North Carolina, Florida and New Jersey, the three states where the international company grows its tomatoes, scrutinized the company’s records and charged it with ignoring laws intended to keep workers safe from toxic pesticide residue. The investigators alleged workers were sent into the fields too soon after dangerous chemicals had been sprayed. The case started three years ago when some workers gave birth to babies with severe birth defects. One mother […]

(Beyond Pesticides, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, February 23, 2009) Permethrin and lindane metabolites are found in children who use lice shampoos containing the insecticides, according to researchers affiliated with the Centers for Disease Control and Prevention. The study, “Pesticide exposure resulting from treatment of lice infestations in school-aged children in Georgia,” published in the February issue of the journal Environment International, is the first to measure children’s exposure to chemical lice treatments. The researchers collected baseline urine samples from 78 enrolled children between the ages of six to ten years of age. About one-third of those children were diagnosed with head lice and subsequently treated with at least one over-the-counter permethrin lice treatment, a prescription lindane treatment, or both. Within seven days of the insecticide application, urine samples were again collected. The permethrin exposed children had significantly higher urinary pryrethoid metabolite levels in their post-exposure urine samples. Lindane metabolites were also elevated in urine samples after treatment. Interestingly, the study states, “Exposed participants appeared to have higher pre-exposure metabolite levels — likely from multiple treatments before enrollment — than unexposed participants.” Pentachlorophenol, a metabolite of lindane, was significantly higher in the urine of those children who used a lice treatment regardless of whether it […]

(Beyond Pesticides, February 19, 2009) The Endocrine Exchange (TEDX) has released a new database on the prenatal origins of endocrine disruption, called Critical Windows of Development. It compares human development in the womb with laboratory research showing where and when low-dose exposures to chemicals have effects. The timeline currently charts three chemicals: dioxin, bisphenol A (BPA), and phthalates. TEDX plans to expand the database to include PCBs, PBDEs, DDT, and other endocrine-disrupting pesticides. Examples of conclusions from the prenatal exposure research include: BPA affects development of the male and female reproductive systems, increases susceptibility to breast cancer and alters behavior in adult animals; Phthalates decrease sperm production and increase body weight; and, dioxin affects male reproduction and the immune system. Before a baby is born it is exposed to a myriad of endocrine disrupting chemicals (EDCs). EDCs interfere with the delicate system of vital hormones, glands and organs that control how a baby develops and functions throughout life. EDCs such as BPA, dioxin and phthalates can penetrate the womb and cause adverse effects at extremely low exposure levels. These chemicals are found in water bottles, food cans, dental resins, cleaning products, cosmetics, fragrances, packaging and construction material, cars, planes, recreational […]

(Beyond Pesticides, February 18, 2009) The Environmental Protection Agency (EPA) is accepting through February 23, 2009 public comments on a petition to cancel all registrations for the herbicide 2,4-D and to revoke all of its tolerances. The petition was filed by the Natural Resources Defense Council (NRDC) in November and published by EPA on December 24, 2008. As the most commonly used “home and garden” chemical, millions of U.S. households especially vulnerable children and pets, are exposed to this toxic chemical. Beyond Pesticides fully supports the cancellation of this dangerous pesticide which has been associated with a host of adverse human impacts, such as non-Hodgkin’s lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. The highly toxic chemical can be replaced by cost-competitive and effective management practices widely used in organic agriculture and lawn care. As long as 2,4-D remains on the market, the public will continue to be exposed to, and suffer the effects of this chemical whose health impacts have long been ignored by EPA. Public health and environmental advocates believe it is time that EPA put science and the health of the public and the environment first and ban […]

(Beyond Pesticides, February 17, 2009) A U.S. District Court Judge has denied a request for remediation in resolving an on-going lawsuit between the victims of the worst industrial disaster in human history in Bhopal, India and Union Carbide, the company responsible for the disaster, according to Reuters, after Union Carbide objected to the victims’ request for remediation. Dow Chemical bought Union Carbide in 2001 and with it, its liabilities for the chemical plant disaster involving the production of methyl isocyanate (MIC), used as an intermediate in the production of the insecticide carbaryl (Sevin). Yet Dow Chemical has refused to clean up the site, provide safe drinking water, compensate the victims, or disclose chemical information to physicians; claiming that the Indian government is responsible for the environmental cleanup. In 1984, Union Carbide was responsible for the 1984 gas leak in Bhopal, India. Forty tons of deadly gas was released. Seven thousand people died in the next few days and 15,000 have died since from illnesses related to the accident. Over 100,000 victims still suffer from illnesses because of this event. In a 1989 settlement, Union Carbide agreed to pay $470 million to victims. However, $330 million still has not been paid […]

(Beyond Pesticides, February 12, 2009) Genetically modified (GM) crops are benefiting biotech food giants instead of the world’s hungry population, which is projected to increase to 1.2 billion by the year 2025 due to the global food crisis, according to a report released yesterday by the Center for Food Safety and Friends of the Earth International. The report, “Who Benefits From GM Crops: Feeding the Biotech Giants Not the World’s Poor,” explains how biotech firms like Monsanto are exploiting the dramatic rise in world grain prices that are responsible for the global food crisis by sharply increasing the prices of GM seeds and chemicals they sell to farmers, even as hundreds of millions go hungry. The findings of the report support a comprehensive United Nations’ assessment of world agriculture in the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD), which in 2008 concluded that GM crops have little potential to alleviate poverty and hunger in the world. IAASTD experts recommended instead low-cost, low-input agroecological farming methods. “U.S. farmers are facing dramatic increases in the price of GM seeds and the chemicals used with them,” said Bill Freese, science policy analyst at the US-based Center for Food Safety […]

(Beyond Pesticides, February 11, 2009) Connecticut lawmakers are taking an interest in the much debated cause of a massive die-off of lobsters that has all but wiped out the state’s 40 million dollar industry, according to the Easton Courier. Fishermen and environmentalists blame the use of the insecticide malathion, a hazardous organophosphate, currently used in community mosquito eradication programs, however the state Department of Environmental Protection (DEP) argues that there is not enough scientific data to lead to the banning of the chemical. The huge die-off of lobsters began in 1999, days after towns in Fairfield County, Westchester County and Long Island, as well as New York City, sprayed malathion to kill mosquitoes carrying the West Nile virus. Also at that time, remnants of hurricane Floyd drenched the state and washed the pesticide into Long Island Sound. The DEP, however, says the storm caused many other factors that led to the mass die-off. However, the lobster population has yet to recover. State lawmakers find DEP’s position on malathion puzzling. Rep. Richard Roy (D-Milford), chair of the House Environment Committee, and Senate Assistant Majority Leader Bob Duff (D-Norwal) are questioning DEP about its efforts to restore the state’s lobster industry while […]

(Beyond Pesticides, February 9, 2009) Baldemar Velásquez, president of the Farm Labor Organizing Committee (FLOC), AFL-CIO, will be speaking at Bridge to an Organic Future, the 27th National Pesticide Forum, April 3-4, 2009 in Carrboro, NC. FLOC, founded by Mr. Velásquez in 1967, is both a social movement and a labor union focusing on migrant workers in the agricultural industry. The FLOC vision emphasizes human rights as the standard and self-determination as the process. The union struggles for full justice for those who have been marginalized and exploited for the benefit of others, and has sought to change the structures of society to enable these people a direct voice in their own conditions. FLOC President Baldemar Velásquez was raised as a migrant farmworker. Since his childhood, he has worked in the fields and orchards of many states from Texas to the Midwest. He suffered the oppression and discrimination of migrant workers, and watched his parents humiliated many times from the injustices they experienced trying to support their family. Finally, after one incident when his father was cheated out of promised wages in front of the family, Baldemar began organizing migrant workers to stand up for their rights. Following the model […]

(Beyond Pesticides, February 9, 2009) The U.S. Environmental Protection Agency (EPA) is currently soliciting comments on Monsanto’s second application to extend its experimental use permit for soybeans genetically engineered (GE) with the soil bacterium Bacillus thuringiensis (Bt). This will be the new administration’s first test on how it handles the issues surrounding GE crops. Among a number of concerns regarding GE crops, crops engineered to contain Bt threaten the long-term efficacy of Bt, which is an approved insecticide in organic farming. Monsanto’s permit on these GE soybeans was first granted by EPA in September 2007 and then extended in April 2008. Under the permit, plantings are permitted through July 31, 2009. Monsanto is requesting to extend the experimental program until December 31, 2010 and amend it by conducting tests with up to 0.466 pounds of Bt Cry1Ac protein in soybeans on 1,362 acres, according to the February 4th Federal Register notice. The testing trials will take place in Arkansas, Illinois, Indiana, Kentucky, Maryland, Missouri, North Carolina, Puerto Rico, South Carolina, and Virginia. Following the review of the application and any comments and data received in response to this solicitation, EPA will decide whether to issue or deny the EUP request, […]

(Beyond Pesticides, February 5, 2009) Former chief environmental correspondent for The New York Times Philip Shabecoff and freelance journalist Alice Shabecoff will be making a rare public talk at Bridge to an Organic Future, the 27th National Pesticide Forum, April 3-4, 2009 in Carrboro, NC. They will be speaking Friday evening at the conference and signing copies of their new book, Poisoned Profits: The toxic assault on our children, during a reception immediately following their presentation. See registration information below. Based on more than five years of investigative research and reporting, Poisoned Profits reveals the cumulative scientific evidence connecting the massive increase in environmental poisons to the epidemic of disability, disease, and dysfunction among our nation ´s children. The authors conclude that the poisoning of the environment is as grave a threat to the future as any problem confronting our nation. Yet even as individual parents and pediatricians struggle to fight illness, one child at a time, the public remains in the dark about the enormity of this crisis. Why? Because, according to the authors, corporations control the system, molding laws to their liking. The book shines a light on the motives and means of corporate-paid lawyers, “product defense” companies, […]

(Beyond Pesticides, February 4, 2009) A new test for triclosan, developed by researchers at the U.S. Department of Agriculture’s Agricultural Research Service (ARS), could help to expedite environmental monitoring of this widely used antibacterial chemical which has been found at high concentrations in rivers and other water resources. Triclosan is linked to a range of health and environmental effects, from skin irritation, bacterial resistance and endocrine disruption, to dioxin contamination and adverse impacts on fragile aquatic ecosystems. The new test called “magnetic particle enzyme immunoassay,” can detect triclosan at a concentration of 20 parts per trillion (ppt)-the equivalent of 1 ounce in 31 million tons. The research team at ARS evaluated the test by using it to detect triclosan and its derivative, methyl-triclosan, in river water, tap water and sewage samples from three municipal plants. They were able to detect triclosan below 20 ppt (the detection limit), indicating very low levels of triclosan in the collected samples. ARS chemist, Weilin L. Shelver, at the ARS Animal Metabolism-Agricultural Chemicals Research Unit in Fargo, N.D., developed the new triclosan test in collaboration with Jennifer Church, Lisa Kamp and Fernando Rubio, a research team at Abraxis, Inc., of Warminster, Pa. Ms. Shelver says […]

(Beyond Pesticides, February 3, 2009) A corporate tomato grower faces an unprecedented penalty of more than $931,000 for misusing pesticides and jeopardizing the health and safety of workers in its New Jersey farm fields and packing houses, New Jersey Department of Environmental Protection (DEP) Acting Commissioner Mark N. Mauriello announced January 30, 2009. In its enforcement action, the DEP cites Ag-Mart Produce Inc., headquartered in Cedarville, Cumberland County, with hundreds of violations that include denying state environmental inspectors access to facilities, losing track of a highly toxic insecticide, failing to properly ventilate areas during pesticide use, failing to post important pesticide-safety information for workers, careless recordkeeping and using forbidden mixtures of pesticides. Ag-Mart Produce widely markets its tomatoes under the brand name “Santa Sweets,” and employs 700 people throughout 17 farm locations in New Jersey. Ag-Mart also owns and operates other produce farms in North Carolina, Florida and Mexico. “Ag-Mart has repeatedly shown a stunning disregard of laws and regulations intended to protect the workers who harvest their tomatoes, the people who consume them and New Jersey’s environment,” Commissioner Mauriello said. “Ag-Mart’s pesticide violations are the most serious DEP inspectors have ever uncovered. We have imposed a record-high penalty not […]

(Beyond Pesticides, January 28, 2009) The U.S. Environmental Protection Agency’s (EPA) national sewage sludge survey identifies high concentrations of toxic contaminants with heavy metals, steroids and pharmaceuticals, including the antibacterials, triclocarban and triclosan. Despite the prevalence of these toxic chemicals in the environment and their potential adverse impacts to human health and the environment, EPA maintains that it is not appropriate to speculate on the significance of the results at this time. Under the Clean Water Act (CWA), Section 405(d) stipulates that EPA must identify and regulate toxic pollutants that may be present in biosolids (sewage sludge) at levels of concern for public health and the environment. The survey, “Targeted National Sewage Sludge Survey” (TNSSS), sampled 74 selected waste water treatment plants in 35 states during 2006 to 2007. The survey, like its three predecessors, is conducted to determine which chemicals are present in sewage sludge and develop national estimates of their concentrations in order to assess whether exposures may be occurring and whether concentrations found may be of concern. The agency conducted analysis of sewage sludge samples for 145 compounds, including four anions (nitrite/nitrate, fluoride, water-extractable phosphorus), 28 metals, four polycyclic aromatic hydrocarbons, two semi-volatiles, 11 flame retardants, 72 […]
