(Beyond Pesticides, October 30, 2009) A recent study shows that women who use insecticides are at elevated risk for autoimmune diseases such as rheumatoid arthritis and lupus. The results of the yet unpublished study were presented on October 17, 2009 at the American College of Rheumatology annual meeting in Philadelphia, PA. The study, which looked at more than 75,000 women, shows that those who spray insecticides at least six times per year have almost two and a half times the risk of developing lupus and rheumatoid arthritis versus those who do not use insecticides. The risk doubles if insecticides were used in the home for 20 years or more. Hiring a gardener or commercial company to apply insecticides also resulted in a doubling of risk, but only if they were used long-term, says Christine G. Parks, PhD, an epidemiologist with the National Institute of Environmental Health Sciences in Research Triangle Park, N.C., one of the lead researchers who analyzed data from the Women’s Health Initiative (WHI) Observational Study. “Our new results provide support for the idea that environmental factors may increase susceptibility or trigger the development of autoimmune diseases in some individuals,” said Dr. Parks. While the study does not […]

(Beyond Pesticides, October 29, 2009) Concerns from the Florida Department of Environmental Protection (DEP) about groundwater contamination in a golf course have temporarily halted the use of an herbicide by the Tampa Sports Authority. Recent soil and groundwater testing in Tampa has revealed higher than acceptable levels of arsenic that may be attributed to the use of the arsenical herbicide monosodium methanearsonate (MSMA) on the golf course, Rogers Park. According to the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Health and Human Services, chronic exposure to organic arsenic, such as MSMA, is known to cause cancer and has been linked to heart disease, diabetes and declines in brain functions. It is also been identified as a potential leacher and is toxic to birds, fish, aquatic organisms and bees. EPA’s Reregulation Eligibility Decision (RED) states that most uses of this product as well as other arsenical herbicides, disodium methanearsonate (DSMA) and hydroxydimethylarsine oxide (cacodylic acid, or sodium salt) are banned except for use on cotton, and will be phased out by the end of 2013, in two phases. In the meantime, many new restrictions apply in an attempt to protect water resources. For instance, MSMA use on golf […]

(Beyond Pesticides, October 28, 2009) Transcripts released last week from an external peer review panel convened in September to evaluate California’s Department of Pesticide Regulation’s (DPR) risk assessment of the fumigant methyl iodide show that the panel’s leading scientists have serious concerns about this chemical. Methyl iodide is currently being considered for use on California’s crops, especially strawberries. The scientific panel held a public workshop, entitled “Methyl Iodide External Peer Review Panel Workshop,” on September 24-25, 2009 in Sacramento, CA as part of an additional, external peer review for methyl iodide. Previously planned public and scientific review processes were subject to cancellation or postponement by the Governor’s office. Led by John Froines, Ph.D., director of the Center for Occupational and Environmental Health at the University of California, Los Angles, the panel consisted of eight experts in various scientific fields. The scientists expressed concern over inadequate buffer zones, ground water contamination and drinking water exposures, body burden, neuro-degeneration, reproductive toxicity and carcinogenicity that are associated with methyl iodide use and exposures. Panel members also challenged EPA’s assessment and found EPA’s scientific conclusions on methyl iodide to be lacking. The transcripts and other workshop presentations are available here. These concerns underscore previous […]

(Beyond Pesticides, October 27, 2009) U.S. District Judge Paul Huck (Miami) has said a multimillion dollar judgment against U.S. food giant Dole and the Dow Chemical Company cannot be enforced because, “[T]he judgment was rendered under a system which does not provide impartial tribunal or procedures compatible with the requirements of due process of law, and the rendering court did not have jurisdiction over Defendants.” A trial court in Chinandega, Nicaragua, had awarded the money in 2005 to 150 Nicaraguan citizens who believe they were injured by exposure to the pesticide dibromochloropropoane, or DBCP, when they worked on Dole banana plantations between 1970 and 1982. This actiion was taken despite findings in the U.S. that DBCP causes sterility and regulatory action to remove it from the market. The trial court awarded Plaintiffs approximately $97 million under “Special Law 364,” enacted by the Nicaraguan legislature in 2000 specifically to handle DBCP claims. The average award was approximately $647,000 per plaintiff. According to the Nicaraguan trial court, these sums were awarded to compensate plaintiffs for DBCP-induced infertility and its accompanying adverse psychological effects. In similar cases in the past, the companies have refused to pay. Dow Chemical has called such judgments “unenforceable” […]

(Beyond Pesticides, October 26, 2009) A new study conducted in China finds that people with organophosphate pesticides in their homes are more likely to have suicidal thoughts. According to the study, “Pesticide exposure and suicidal ideation in rural communities in Zhejiang province, China,” published in the October issue of the WHO Bulletin, there is biological evidence that chronic low-grade exposure to organophosphate pesticides, which are very easily absorbed into the body through the skin and lungs, may have adverse effects on mental health. The study was carried out in the central/coastal region of China, a relatively wealthy area with a rapidly developing economy. In a very large survey of mental health in rural community residents, participants were also asked about how they stored pesticides. The study found that people who stored pesticides at home, i.e. those with more exposure, were more likely to report recent suicidal thoughts. Supporting this, the survey also found suicidal thoughts to be associated with how easily accessible these pesticides were in the home and that the geographic areas with highest home storage of pesticides also had highest levels of suicidal thoughts in their populations. “Organophosphate pesticides are widely used around the world. They are particularly […]

(Beyond Pesticides, October 23, 2009) The U.S. Environmental Protection Agency (EPA) fined Samsung for violating the federal pesticide law when it publicized that its keyboards, produced with nanosilver, were antimicrobial and inhibited germs and bacteria without registering its products with EPA. The claims made on the company’s labels and promotional material for netbook and notebook computer laptops would render the products pesticides, requiring registration by EPA. Dell also has keyboards treated with nanosilver for antimicrobial purposes which are registered with EPA. Nanosilver has been promoted for its antibacterial properties and is used in many products such as sporting goods, band-aids, clothing, baby and infant products, and food and food packaging. However, very little is known about where these particles end up when such products are put to use. Many consider silver to be more toxic than other metals when in nanoscale form and that these particles have a different toxicity mechanism compared to dissolved silver. Scientists have concluded that nanoparticles can pass easily into cells and affect cellular function, depending on their shape and size. Preliminary research with laboratory rats has found that silver nanoparticles can traverse into the brain, and can induce neuronal degeneration and necrosis (death of cells […]

(Beyond Pesticides October 22, 2009) At least seven million inhabitants of Moldavia and Ukraine are endangered by 10,000 tons of old pesticides. This has been reported by the International HCH and Pesticides Association (IHPA). According to the organization the EU must act as fast as possible to disarm this ”˜biggest chemical time bomb of Europe.’ This position was adopted at the closure of the 10th HCH & Pesticides Forum of the IHPA in the Czech Republic. During the congress, it became known that in the former Kalush factory in the west of Ukraine there is a stockpile of no less than 10,000 ton of superfluous Hexachlorobenzene (HCB). The factory location along the Dniester River makes the situation extremely hazardous: a single flood and the high concentrations of poison would pollute the natural habitat of some seven million people in the west of Ukraine and Moldavia. Pesticides are threatening tens of millions of people living throughout Europe, Central Asia, and the former Soviet Union, accordding to the statement. There is an estimated 178,000 to 289,000 tons of obsolete pesticides stockpiled throughout the European Union, Southeast Europe, and the former Soviet Union. Ukraine alone has 4,500 storage locations with over 30,000 tons […]

(Beyond Pesticides, October 21, 2009) The U.S. Environmental Protection Agency (EPA) is making available the battery of scientific assays and test guidelines for conducting the assays for each of 67 chemicals included for Tier 1 testing for endocrine disrupting effects during the next three months. This comes after the Office of Management and Budget (OMB) instructed EPA to use existing toxicity data rather than require companies to conduct new tests to determine whether chemicals can damage the human endocrine system. With the availability of the assays and test guidelines, EPA will move forward with issuing test orders to manufacturers to compel the generation of the needed data. However, acquisition of new, relevant data may be limited. This is because after EPA submitted the request for additional information for OMB approval, the Office issued a directive that approved EPA’s request to collect additional data for the 67 chemicals but warned the agency that it should “to the greatest extent possible” accept existing data to satisfy test requirements. The OMB directive, which observers say contains unusually strong language, is being hailed by industry groups that had been concerned about the prospects for expensive testing mandates. But many environmental groups and scientists say […]

(Beyond Pesticides, October 20, 2009) The U.S. Department of Agriculture (USDA) and the Environmental Protection Agency (EPA) are asking farmers to use coal ash to grow their crops, despite a paucity of research on possible risks, according to documents released October 15, 2009 by Public Employees for Environmental Responsibility (PEER). USDA endorses use of coal combustion wastes by farmers “for crop production,” while acknowledging uncertainty on the extent to which “toxic elements” are absorbed into produce entering the market. Beyond Pesticides points out that coal ash is just one of many toxic products “recycled” into fertilizer and encourages people to avoid chemical fertilizers all together in favor of compost and other organic methods. This month, USDA enters the final year of a three-year partnership with EPA as part of a larger effort by the American Coal Ash Association, the Electric Power Research Institute and others to “promote appropriate increased use of” coal ash in agriculture. The implementing Memorandum of Understanding obliges USDA to generate “documentation of the effectiveness, safety and environmental benefits, including bioavailability of trace elements such as mercury, arsenic and selenium”¦to satisfy the concerns of producers, generators, regulators and the public.” According to EPA, agriculture annually uses more […]

(Beyond Pesticides, October 19, 2009) The “green” movement continues to sprout throughout New Jersey, as Hamilton Township joins other municipalities in the state that have made their parks pesticide-free zones and have adopted an Integrated Pest Management (IPM) program for managing town property. Responding to the request of local members of the New Jersey Environmental Federation, Hamilton Township recently passed a resolution adopting the Federation’s model pesticide reduction policy. The policy establishes Pesticide Free Zones for 50 feet surrounding township playgrounds, picnic grounds, pavilions and rest areas, dog parks and ballfields, as well as 300 feet from any stream bank, pond, lake or natural wetland. It also requires the implementation of an IPM program for all township buildings and grounds. Hamilton Mayor John F. Bencivengo endorsed the policy, stating that it is a great way to educate the public about pesticide use, and ensure that the township continues on its path of “pesticide free zones” in its parks, municipal building and library. Schools in New Jersey are already required by law to follow IPM plans using non-toxic methods first and conventional pesticides only if the non-toxic methods are ineffective. “It is easy to manage a lawn without harmful chemical pesticides,” […]

(Beyond Pesticides, October 16, 2009) On October 14th, Earthjustice and Farmworker Justice filed a petition asking the U.S. Environmental Protection Agency (EPA) to set safety standards protecting children who grow up near farms from the harmful effects of pesticide drift. The groups are also asking the agency to adopt an immediate no-spray buffer zone around homes, schools, parks and daycare centers for the most dangerous and drift-prone pesticides, organophosphates. The petition was filed by the public interest law firms on behalf of farmworker groups: United Farm Workers, Oregon-based Pineros y Campesinos Unidos del Noreste, California Rural Legal Assistance Foundation, and the Farm Labor Organizing Committee, AFL-CIO as well as Physicians for social Responsibility, Washington-based Sea Mar Community Health Center, Pesticide Action Network North America, and MomsRising.org. Specifically, the petition states that the EPA has failed to address the facts that children are particularly vulnerable to pesticides according findings by the National Academy of Sciences (NAS) in 1993. Congress took recommendations from NAS and passed the Food Quality Protection Act in1996, requiring EPA to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure” to pesticides. However, while EPA has made some […]

(Beyond Pesticides, October 15, 2009) New research from the Monell Center and the Mount Sinai School of Medicine reveals that phenoxy herbicides block T1R3, a nutrient-sensing taste receptor found in the pancreas and intestines of humans. These commonly used herbicides were not previously known to act on the T1R3 receptor, nor has any animal testing revealed any indication of this. The specific effects are unique to humans; thus, phenoxy herbicides may have adverse metabolic effects in humans that would have gone undetected in studies on rodents. The T1R3 receptor is a critical component of both the sweet taste receptor and the umami (amino acid) taste receptor. First identified on the tongue, emerging evidence indicates that T1R3 and related taste receptors also are located on hormone-producing cells in the intestine and pancreas. These internal taste receptors detect nutrients in the gut and trigger the release of hormones involved in the regulation of glucose homeostasis and energy metabolism. “Compounds that either activate or block T1R3 receptors could have significant metabolic effects, potentially influencing diseases such as obesity, type II diabetes and metabolic syndrome,” noted Monell geneticist and study leader Bedrich Mosinger, M.D., Ph.D. The study, co-authored by Emeline Maillet from the Department […]

(Beyond Pesticides, October 14, 2009) New research by scientists at the Swiss Federal Laboratories for Materials Testing and Research provides a first look at the behavior of nanosilver textiles under real-world washing conditions. This work builds on earlier studies conducted in water which show that nanosilver leaches from fabrics and textiles during washing to enter the environment. The study, “The Behavior of Silver Nanotextiles during Washing” published in Environmental Science and Technology, found that the total amount and form of silver (dissolved or particulate) that leaches during washing varies significantly depending on the product and the conditions. The goal was to determine the amount and the form of silver released during washing from nine fabrics with different ways of silver incorporation into or onto the fibers. The effect of pH, surfactants, and oxidizing agents was also evaluated. In the washing machine the majority of the nanosilver (at least 50% but mostly >75%) was released in the size fraction more than 450 nm, indicating the dominant role of mechanical stress. The researchers found that under typical washing conditions (pH 10—11, with high levels of surfactants), dissolved concentrations of silver were 10 times lower than at pH 7. However, when bleaching agents […]

(Beyond Pesticides, October 13, 2009) In a first ever investigation of toxic chemicals found in the bodies of doctors and nurses, Physicians for Social Responsibility (PSR) in partnership with American Nurses Association (ANA) and Health Care Without Harm (HCWH) released the Hazardous Chemicals In Health Care report on October 8th. The inquiry found that all of the 20 participants had toxic chemicals associated with health care in their bodies. Each participant had at least 24 individual chemicals present, four of which are on the recently released US Environmental Protection Agency (EPA) list of priority chemicals for regulation. These chemicals are all associated with chronic illness and physical disorders. The Hazardous Chemicals in Health Care report offers preliminary indicators of what the broader health care community may be experiencing. The project tested for 62 distinct chemicals in six categories: bisphenol A, mercury, perflourinated compounds, phthalates, polybrominated diphenyl ethers, and triclosan. The chemicals tested in the investigation are used in products common to the health care setting, from baby bottles, hand sanitizer, and medical gauges, to industrial paints, IV bags and tubes and stain-resistant clothing. Twelve doctors and eight nurses, two in each of 10 states were tested for the presence of […]

(Beyond Pesticides, October 9, 2009) An Australian Government study has shown that lice on sheep may be controlled by fungal biopesticides. Scientists from Queensland Primary Industries and Fisheries (QPIF) in Queensland, Australia have achieved promising results using a naturally occurring fungus called Metarhizium isolated from Queensland soil as an insecticide. “When the fungal spores are applied to the sheep, they stick to the surface of lice as they move around in the fleece,” explains QPIF Senior Scientist Diana Leemon, PhD. “The lice also consume spores as they feed on wool grease and the spores germinate inside the insect, killing it.” Tim Mulherin, Minister for Primary Industries, Fisheries and Rural and Regional Queensland, stated, “Livestock industries, including sheep, are extremely important to our economy. Parasites such as sheep lice damage wool and reduce yields, leading to significant losses for the producer. Lice cost the Australian wool industry $123 million annually through lost production and control costs.” QPIF and Australian Wool Innovation Limited (AWI) have signed an agreement with commercial partner Becker Underwood Australia to develop the biopesticide to help the lice problem. AWI CEO Brenda McGahan said the research was timely as sheep lice are building resistance to some current treatments. […]

(Beyond Pesticides, October 8, 2009) The U.S. Environmental Protection Agency (EPA) announced that it will launch a comprehensive new evaluation of the pesticide atrazine to determine its effects on humans this fall. At the end of this process, the agency will decide whether to revise its current risk assessment of the pesticide and whether new restrictions are necessary to better protect public health. This announcement follows recent scrutiny and findings that the current EPA regulation of atrazine in water is inadequate. In August this year, the Natural Resources Defense Council (NRDC) published a report, Poisoning the Well which found that the commonly used herbicide atrazine can spike at extremely high levels which go undetected by regular monitoring. Concurrently, The New York Times published an investigative piece based on the NRDC findings and confirmed that the public is not informed when reports of these spikes of atrazine in drinking water occur. One of the most widely used agricultural pesticides in the U.S., atrazine can currently legally be applied before and after planting to control broadleaf and grassy weeds. Its increased use to manicure home lawns and gardens has become a serious environmental concern as runoff has had severe health and environmental […]

(Beyond Pesticides, October 7, 2009) The U.S. Environmental Protection Agency (EPA) is establishing a new transparent process that will allow the public to review and comment on risk assessments and proposed registration decisions for pesticides. This expanded process will apply to all new pesticide active ingredients and first food uses, first outdoor uses, and first residential uses. It is not clear at this writing whether the agency will at the same time release the underlying test data on potential adverse health effects that companies submit for product registration. Starting October 1, 2009, the public will be able to review and comment on the risk assessments and proposed registration decisions for certain pesticide registration actions. Upon receiving a complete application for registration for a new pesticide active ingredient or a new use of an already registered active ingredient, EPA will publish a Federal Register Notice of Receipt, establish a case docket in regulations.gov, and open an initial 30-day public comment. Following the comment period, EPA will publish its decision and a response-to-comment document. Once the agency’s risk assessments and proposed decision for the registration application are added to the docket, EPA will open another 30-day public comment period. After the final […]

(Beyond Pesticides, October 6, 2009) What started as a one-acre pilot project and grew into a 16-acre test, is now going to be taking over the entire Harvard University campus grounds. Harvard has committed to managing its entire 80-acre campus with pesticide-free, natural, organic lawn and landscape management strategies, all the while saving tens of thousands of dollars a year. According to the Harvard Yard Soils Restoration Project Summary Report, the pilot project was modeled after New York City’s Battery Park City Parks’ 37-acre organic landscape program that began back in 1989. The goal of the project was simply to improve soil health, develop knowledge base on how to run such programs as well as educate the campus community about the many benefits or organic lawn care. For eight months, the one-acre test plot was extensively compared to a control plot of conventional management techniques. That one-acre underwent a process that included eliminating all toxic pesticides, testing for soil nutrients and organic material content, and adding compost teas to balance soil nutrients and reduce irrigation and nitrogen applications. The compost tea, a liquid biological amendment from the brewing vat located nearby, is made up of liquid humic acid and North […]

(Beyond Pesticides, October 5, 2009) An analysis of more than 100 scientific studies conducted on atrazine, published in the online edition of Environmental Health Perspectives, demonstrates the toxicity of atrazine to aquatic animals. Biologists at the University of Southern Florida (USF) have found evidence that atrazine harms fish and frogs. Atrazine is disruptive to the development and behavior of aquatic animals, and negatively effects their immune, hormone, and reproductive systems, according to the studies done by USF assistant professor Jason R. Rohr and postdoctoral fellow Krista A. McCoy. Atrazine is commonly used on lawns, golf courses, and sugarcane fields in Florida, and has recently been the topic of much controversy. While atrazine typically does not kill amphibians and freshwater fish, the USF report says it did: ”¢ Reduce the size of amphibians at or near metamorphosis in 19 of 19 studies. ”¢ Make amphibians and fish more active in 12 of 14 studies but reduced behaviors used to evade predators in six of seven studies. ”¢ Alter at least one aspect of male frogs’ reproductive development in eight of 10 studies. ”¢ Reduce the functioning of animals’ immune systems and often put them at risk of infection. Atrazine, a common […]

(Beyond Pesticides, October 2, 2009) The Environmental Protection Agency (EPA) announced that it is moving forward with a plan to disclose the identities of all so-called “inert’ ingredients in pesticides, including those that are potentially hazardous. EPA believes this increased transparency will assist consumers and users of pesticides in making informed decisions and will better protect public health and the environment. Pesticide manufacturers typically disclose their inert ingredients only to EPA. On September 30, 2009, EPA responded to two petitions, one by led by the Northwest Coalition for Alternatives to Pesticides and joined by Beyond Pesticides and 20 other organizations, and a second by certain State Attorneys General, that identified over 350 inert pesticide ingredients as hazardous. The petitioners asked EPA to require these inert ingredients be identified on the labels of products that include them in their formulations. In its response to petitioners, the agency said, “EPA agrees with the petitioners that the public should have a means to learn the identities of hazardous inert ingredients in pesticide product formulations. The agency believes that increased transparency could lead to better informed decision making and better informed pesticide use.” It continues, “EPA will also be discussing ideas to increase disclosure […]

(Beyond Pesticides, October 1, 2009) More pesticides and fertilizers used to grow conventional corn would find their way into nearby water sources if ethanol demands lead to planting more acres in corn, according to a Purdue University study. The study of Indiana water sources finds that fields practicing continuous-corn rotations have higher levels of nitrogen, fungicides and phosphorous than corn-soybean rotations. While touted as a green energy source, most corn ethanol is made with genetically modified corn that is routinely sprayed with pesticides and chemical fertilizers. To makes matters worse, it’s usually planted year after year, rather than using crop rotation, a basic strategy to reduce pest pressure and soil erosion. Corn ethanol is also inefficient, producing only 1.34 joules of energy for each joule used in production (compared to 8 joules for sugarcane). Furthermore, the American Clean Energy and Security Act (House Climate Bill) sidetracks a proposed EPA regulation that requires U.S. ethanol makers responsible for greenhouse gas emissions from conversion of forests and grasslands overseas to cropland. Big Agribusiness is lobbying for a similar provision in the Senate version, the Clean Energy Jobs and American Power Act. Results of the new study, “Water Quality Impacts of Corn Production […]

(Beyond Pesticides, September 30, 2009) The Center the Food Safety and the Resource Institute for Low Entropy Systems have petitioned the City of San Francisco and the San Francisco Public Utilities Commission (SFPUC) to immediately suspend the SFPUC’s Compost Giveaway program because the compost is made with sewage sludge which contains toxic chemicals and hazardous materials. The petition, submitted last Wednesday, cites that the distribution of contaminated compost will spread toxic sludge to homeowners’ backyards, increasing the risk of health problems to children and the community. The SFPUC’s compost giveaway program distributes free compost as part of the commission’s recycling efforts to community gardens, school gardens and local residents. The compost is made of sewage sludge, derived as a by-product of wastewater and sewage treatment, and contains heavy metals, pathogens, pharmaceuticals, PCB’s, flame retardants and endocrine disruptors, such as the antibacterial triclosan. “San Franciscans may think they’re getting a gift from the city, but this is no gift. City residents could be at serious risk of poisoning from the application of sewage sludge to local crops and gardens,” said Paige Tomaselli, staff attorney for the Center for Food Safety. “With this petition, we’re strongly urging the Mayor to put an […]

(Beyond Pesticides, September 29, 2009) A new study reveals that children exposed to agricultural pesticides applied near their home have up to twice the risk of developing the most common form of childhood leukemia, according to the Northern California Cancer Center (NCCC). The study, “Residential proximity to agricultural pesticide applications and childhood acute lymphoblastic leukemia,” published in the October issue of Environmental Research, used a unique California database to reveal an elevated risk in acute lymphoblastic leukemia (ALL) among children living near applications of certain categories of pesticides used in agriculture. The study, led by Rudolph Rull, Ph.D., shows an elevated risk of ALL associated with moderate exposure, but not high exposure, to pesticides classified as organophosphates (odds ratio (OR) 1.6), chlorophenoxy herbicides (OR 2.0), and triazines (OR 1.9), and with agricultural pesticides used as insecticides (OR 1.5) or fumigants (OR 1.7). California is one of the few states in the country that requires active reporting of pesticide applications, including time, place, and the type and amount of pesticide used. For this study, researchers were able to link children’s entire residential histories from birth to the time of case diagnosis to this pesticide-use reporting database and identify agricultural pesticides that […]
