(Beyond Pesticides, May 28, 2010) The repeated exposure to organophosphate and organochlorine insecticides can increase the risk of developing Alzheimer’s Disease (AD) or dementia later in life according to a new study published in the May issue of Neurology. The observational study entitled “Occupational exposure to pesticides increases the risk of incident AD” is one of very few studies to examine a link between pesticides and AD. Researchers lead by Kathleen M. Hayden, PhD of Duke University Medical Center examined residents 65 years and older from an agricultural community in Cache County Utah. Participants were assessed for cognitive ability at the inception of the study and again after 3, 7, and 10 years. Data showed that those repeatedly exposed to any pesticides were more likely to develop AD or dementia. Researchers found a higher incidence of AD among those exposed to organophosphates and organochlorines. The risk of AD associated with organophosphate exposure was slightly higher than the risk associated with organochlorines. Researchers also found an increase in dementia among those exposed to organophosphates or organochlorines; however this increase was not statistically significant. Dr. Hayden said that more research was necessary to determine a causal link. Organophosphates are known to reduce […]

(Beyond Pesticides, May 27, 2010) A new report showcases the pitfalls of the U.S. Green Building Council’s LEED certification program in regards to protecting human health from environmental hazards. The report, “LEED Certification: Where Energy Efficiency Collides With Human Health,” put out by Environment and Human Health, Inc. (EHHI), warns that the LEED certification gives a false impression of a healthy and safe building environment and offers recommendations for the program to become more protective of human health. EHHI found that LEED standards have been incorporated into many federal, state and local laws, and many other corporations and other institutions have adopted LEED standards as well. Although this has encouraged energy efficiency in buildings, according John Wargo, Ph.D., lead author of the study and professor of Risk Analysis and Environmental Policy at Yale University, it has been implemented without fully understanding that energy conservation efforts often reduce the exchange of indoor and outdoor air, which can cause synthetic chemicals to concentrate within buildings. “Tighter buildings often concentrate chemicals released from building materials, cleaning supplies, fuel combustion, pesticides and other hazardous substances,” he said. Energy efficiency is given a high priority over health. The report found that about four times as […]

(Beyond Pesticides, May 26, 2010) Beyond Pesticides has drafted sample text (see below), and we need your help to deliver a letter to your local supermarket, cosmetics store or co-op asking them to stop selling products that contain triclosan. Hundreds of products containing the antibacterial chemical triclosan decorate the shelves of retail stores across the country. From hand soap and toothpastes, to toys and yoga mats, triclosan is everywhere. Product labels will read “triclosan,” “triclocarban” (a related compound found in bar soaps) or “Microban” (a formulation of triclosan used in plastics and fabrics). It is time to take action and demand that this endocrine disrupting chemical is removed from the products we use and love. When consumers demand more for their health and well-being, retailers and manufacturers of triclosan products must listen. Triclosan, which has a similar chemical structure as dioxin, is linked to various health and environmental problems. It is associated with skin irritation, has been shown to interfere with the body’s hormones, and has been linked to an increased risk of developing respiratory illness, or asthma, and cancer, as well as subtle effects on learning ability. Because the chemical goes down the drain, it wreaks havoc with the […]

(Beyond Pesticides, May 25, 2010) An analysis of 266 potential environmental contributors to type 2 diabetes published May 20, 2010 in the online edition of the journal PLoS ONE, links the disease to individuals who have higher levels of polychlorinated biphenyls (PCBs) and the pesticide heptachlor, as well a form of vitamin E found at high levels in soybean and corn oil, in their bodies compared to the general population. PCB was banned in 1979 and most uses of heptachlor were canceled between 1978 and 1989 (except for limited control of fire ants, which continues), but the compounds persist in the environment, especially near former industrial sites or contaminated soil. Environmentalists point to the fact that chemicals banned decades ago are still increasing people’s risk of disease, as a reason to take a precautionary approach when evaluating and registering chemicals. The analysis, led by Atul Butte, MD, PhD, assistant professor of medical informatics and pediatrics at the Stanford University School of Medicine, drew on data collected by the Centers for Disease Control and Prevention as part of the National Health and Nutrition Examination Survey (NHANES) to examine a wide range of environmental influences on type 2 diabetes. Dr. Butte conceived […]

(Beyond Pesticides, May 24, 2010) It’s that time of year again when mosquitoes start breeding and biting, so Beyond Pesticides is releasing a new radio Public Service Announcement (PSA) on how to prevent mosquitoes and toxic pesticides from pestering you. Please send the mosquito prevention PSA below to your local radio station to help spread the word to others and keep your community mosquito- and pesticide-free. Let us know by email or Facebook the radio station’s name, city and state so we can follow-up! Mosquito Prevention PSA (30-seconds) “Want to know how to protect yourself and your family from mosquitoes and toxic chemicals?

(Beyond Pesticides, May 21, 2010) Governor Patterson of New York signed the Child Safe Playing Field Act into law on Tuesday, marking a huge victory for grassroots environmental and human health groups. The law helps to protect children by banning the use of pesticides on school playing fields and play grounds. Schools will have one year to comply with the regulations. In New York and across the country, schools routinely apply pesticides and “weed and feed” products (pesticides mixed with chemical fertilizers), which are linked to cancer, endocrine disruption, learning disabilities, asthma and other problems. Strong opposition from the pesticide industry had led to a previous version of the bill being defeated nine times. While the earlier versions of the legislation included all outdoor school grounds, the scope was narrowed to include only playgrounds and playing fields to help ensure passage. In addition, over 8,000 letters were sent to legislators in favor of the bill and over 18,000 people signed a petition, according to Citizens Campaign for the Environment. The Child Safe Playing Field Act requires that all schools, preschools, and day care centers both public and private to stop using pesticides on any playgrounds or playing fields. The law […]

(Beyond Pesticides, May 20, 2010) Dioxins derived from the antibacterial agent triclosan account for an increasing proportion of total dioxins found in water: researchers at the University of Minnesota found that though levels of all other dioxins have dropped by 73-90% over the last thirty years, the levels of four different dioxins derived from triclosan have risen by 200-300%. The study, which was a collaborative effort between researchers at the University of Minnesota, Pace Analytical (Minneapolis), the Science Museum of Minnesota and Virginia Tech appears in the journal Environmental Science and Technology. Leading the research is the recent Ph.D. graduate in chemistry, Jeff Buth and supervisors William Arnold, a civil engineering professor, and his colleague Krostopher McNeill, all from University of Minnesota. Researchers looked at sediment core samples that contained pollution accumulation records from the past 50 years from Lake Pepin, a part of the Mississippi River 120 miles downstream from the Minneapolis-St. Paul metro area. The sediment samples were then analyzed for triclosan, the four dioxins that are derived from triclosan and the entire family of dioxin chemicals. In papers published in 2003 and 2009, Dr. Arnold and Dr. McNeill discovered that triclosan, when exposed to sunlight, generated a […]

(Beyond Pesticides, May 19, 2010) EPA has announced plans to place additional limitations on the use of three N-methyl carbamate pesticides — carbaryl, carbofuran and methomyl — to protect endangered and threatened salmon and steelhead in California, Idaho, Oregon and Washington, in compliance with the Endangered Species Act. The decision comes after manufacturers of the chemicals diazinon, malathion and chlorpyrifos refused to adopt the limits voluntarily. The new protections are based on recommendations by the National Marine Fisheries Service (NMFS) in their April 2009 Biological Opinion relative to use of the three pesticides to ensure no likely jeopardy to 28 threatened or endangered Pacific salmon and steelhead species. In a May 14, 2010 letter to NMFS, EPA explains how the Agency plans to achieve protection goals through the methods outlined by NMFS in the Biological Opinion or by alternative methods that EPA’s scientific analyses determined will achieve the same purpose. For example, EPA will require pesticide drift buffers adjacent to salmon and steelhead habitat but will impose different width buffers, some wider and others narrower than those recommended by NMFS, depending on factors that affect how far the pesticide might drift from the application site. In correspondence to the EPA […]

(Beyond Pesticides, May 18, 2010) A team of scientists from the University of Montreal and Harvard University have discovered that exposure to organophosphate pesticides is associated with increased risk of Attention-Deficit Hyperactivity Disorder (ADHD) in children. Using data from the National Health and Nutrition Examination Survey, the study focused on 1,139 children from the general U.S. population and measured pesticide breakdown product levels in their urine. The authors conclude that exposure to organophosphate (OP) pesticides, at levels common among U.S. children, may contribute to a diagnosis of ADHD. “Previous studies have shown that exposure to some organophosphate compounds cause hyperactivity and cognitive deficits in animals,” says lead author Maryse F. Bouchard, a professor at the University of Montreal Department of Environmental and Occupational Health and scientist at the Sainte-Justine Hospital Research Center. “Our study found that exposure to organophosphates in developing children might have effects on neural systems and could contribute to ADHD behaviors, such as inattention, hyperactivity, and impulsivity.” Marc Weisskopf, PhD, ScD, another study author told Reuters, “What this paper specifically highlights is that this may be true even at low concentrations.” For children with a 10-fold increase in the concentration of the most common dialkyl phosphate metabolites […]

(Beyond Pesticides, May 17, 2010) The City of Evanston in Cook County, Illinois has passed a resolution to reduce pesticide use on City-owned and leased property (buildings and grounds) when the City Council unanimously adopted the “Sustainable Pest Control and Pesticide Reduction Policy” on April 26, 2010. The policy requires City employees, agents and contractors to follow natural lawn care and “least-toxic Integrated Pest Management” (IPM) and prohibits high hazards pesticides. It shouldn’t be too difficult for the City, as according to Evanston’s website, the City “has been applying minimal to no pesticides or insecticides in its municipal parks and on City owned properties since the early 1990s.” IPM is described in the policy as, “A pest management technique that gives preference to the safest pest control methods and uses conventional chemical pesticides only when no other feasible alternative exists. It addresses the underlying causes of pest problems, and seeks to find effective long-term solutions that emphasize prevention.” The City will hold a training session at least once every two years for managers and staff responsible for pest management on City property. All contractors engaged in pest management on City property are also required to attend the trainings or must […]

(Beyond Pesticides, May 14, 2010) As the current economic climate forces spending cuts on health benefits, salaries, and bonuses, many companies are offering their employees a trendy new perk: an organic corporate garden. The New York Times reports that dozens of companies from various industries have started or plan to start organic gardens for their employees. Employees may spend a few lunch breaks planting, weeding, and watering, in exchange for all the fresh beans, tomatoes, and zucchini they want. Some of these gardens also supply the company cafeteria, or the local food bank. Companies have put container gardens on rooftops, converted former smoking areas, or simply dug into the office park lawns. In some cases employees lobbied for a garden in others it was a manager that decided to create one. It may come as no surprise that famously progressive companies such as Google have created gardens for its employees but more traditional companies have also joined in the trend. PepsiCo, the $60 billion manufacturer of highly processed products, including Mountain Dew, Amp Energy Drink, Doritos, and Cap’n Crunch, has created an organic garden a five minute walk from corporate headquarters in Purchase, New York. The garden at Kohl’s Department […]

(Beyond Pesticides, May 13, 2010) Recent tests find that mosquitoes that are insensitive to DEET, the pesticide commonly used to repel the pesky flying insect, can pass this characteristic as a genetic trait onto their offspring. The findings are published in the May 3 edition of the journal Proceedings of the National Academy of Sciences. In order to hunt for blood, female mosquitoes use their antenna to locate humans; however, according to researchers, DEET temporarily destroys an insect’s sense of smell by hindering the function of certain odor receptors. The researchers observed which insects bit DEET-treated human arms and discovered that a gene alteration prohibited a sensory cell on the bugs’ antennae from detecting the chemical. “There is something in the antenna they use to smell that reacted differently,” Dr. Nina Stanczyk of Rothhamstead Research, an agricultural research center in the U.K., told the Toronto Star. Scientists studied one species of DEET-insensitive mosquitoes, the Aedes aegypti, a species that carry the diseases yellow fever and dengue fever. When mutated females were bred with males of unknown sensitivity in tests, the quantity of mosquitoes that were insensitive to DEET rose from 13 to 50 percent in one generation. Though scientists are […]

(Beyond Pesticides, May 12, 2010) Disturbed to learn that an advisory committee in his community in Boulder, Colorado had approved two new herbicides for use on city parks, a 9-year-old environmental activist organized a group of some two dozen children to protest the potential use of the herbicides in front of the Boulder County Courthouse last Friday. Xiuhtezcatl Roske-Martinez is a third grader who loves playing kickball and baseball in Boulder city parks. But then he heard that the advisory committee had approved two new herbicides for use on city parks. “I didn’t think it was right,” he said. “The children of this generation should be able to grow up without worrying about the air they’re breathing or the grass they’re playing on.” The Integrated Pest Management Subcommittee – made up of representatives of three city boards – recommended that Boulder add the herbicides, Tenacity and Barricade, to the list of allowed turf treatments. Xiuhtezcatl organized a group of some two dozen children to protest the potential use of the herbicides. They gathered Friday in front of the Boulder County Courthouse on the Pearl Street Mall waving hand-lettered signs that read “Let us play in clean parks,” “We love dandelions” […]

(Beyond Pesticides, May 11, 2010) Even with the growing body of evidence linking environmental exposures to cancer in recent years, a report released May 6, 2010 by the President’s Cancer Panel finds that the true burden of environmentally-induced cancer is greatly underestimated. The Panel’s report, Reducing Environmental Cancer Risk: What We Can Do Now, concludes that while environmental exposure is not a new front on the war on cancer, the grievous harm from this group of carcinogens has not been addressed adequately by the nation’s cancer program. “There remains a great deal to be done to identify the many existing but unrecognized environmental carcinogens and eliminate those that are known from our daily lives — our workplaces, schools and homes,” said LaSalle D. Leffall, Jr., M.D., chair of the Panel. “The increasing number of known or suspected environmental carcinogens compels us to action, even though we may currently lack irrefutable proof of harm,” he added. Beyond Pesticides applauds the chairman’s precautionary approach and encourages President Obama to heed the panel’s call to “use the power of your office to remove the carcinogens and other toxins from our food, water, and air that needlessly increase health care costs, cripple our Nation’s […]

(Beyond Pesticides, May 10, 2010) The environmentally friendly ladybug is alive and well in Ocean Township, New Jersey, thanks to a newly adopted Township resolution that declares parks, playgrounds, and fields as “Pesticide Free Zones;” requires Township property to be managed with Integrated Pest Management (IPM), a program that manages and prevents pests using environmental information, with a focus on non-chemical pest management methods and tools (sanitation, mechanical, biological and, as a last resort, “least toxic” chemicals) that are least likely to impact human health or the environment. The Township’s goal is to eliminate the use of pesticides, while encouraging citizens to do the same. According to Ray Pogwist, Chair of the Ocean Township Environmental Commission, the IPM policy for the township identifies key sensitive areas like the village parks to be managed without harmful chemical pesticides. These areas will be posted with a sign indicating that chemical pesticides have not been applied to the site. “Ocean Township’s action reinforces their commitment to protecting parks and open spaces and reducing its pesticide use,” said Jane Nogaki, program coordinator for NJ Environmental Federation (NJEF). “Since IPM is now the law on all New Jersey school grounds, it makes perfect sense to […]

(Beyond Pesticides, May 7, 2010) Human Rights Watch has released a scathing report entitled “Fields of Peril” on the treatment of child farm workers in the United States. To compile the report, Human Rights Watch interviewed child and young adult farm laborers and parents in all regions of the country, as well as farm managers, and owners, lawyers, doctors, social workers, nurses, and government officials. A previous report entitled “Fingers to the Bone” was released in 2000. Their research shows that conditions have not changed much for the estimated 300,000 to 400,000 child farm workers in the United States. Exposure to pesticides, long hours in extreme weather, the use of heavy machinery, and demanding physical labor makes farm work one of the most dangerous jobs in the United States. According to the Centers for Disease Control’s National Institute for Occupational Safety and Health (NIOSH) farm work is the most dangerous work open to children. Yet child farm workers have much less protection under the Fair Labor Standards Act (FLSA) than children in any other industry. According to the report, even the minimal protections established by the FLSA are often ignored by employers. Impoverished farmworkers fearing the loss of their jobs […]

(Beyond Pesticides, May 6, 2010) The European Commission has announced that triclosan has been formally withdrawn from the European list for use as a food contact additive; however, plastic materials that are intended to come in contact with food and placed on the market before November 2010 may still be sold until November 2011. The decision follows the European Union’s 2009 regulations to impose limits on the amount of triclosan contained in cosmetics. Ciba, the Swiss-based company that is a subsidiary of BASF, announced last year that they had withdrawn the application of triclosan as a food contact additive so that they could instead focus their sales in the personal hygiene, health care and medical device sector. The company declared this to be a “strategic business decision” and declared that triclosan use as as an additive in plastics intended to come into contact with food was no longer “appropriate.” In the U.S. in 2009, Ciba requested a voluntarily cancellation of the registrations for the technical grade triclosan regulated by the U.S. Environmental Protection Agency (EPA) and incorporated into plastics and textiles. Ciba continues to market triclosan for medical and personal care products, which are regulated by the U.S. Food and […]

(Beyond Pesticides, May 4, 2010) On April 30, 2010, despite significant cancer and reproductive health risk, especially to farmworkers and people living near agricultural fields, the California Department of Pesticide Regulation (DPR) proposed the use of a new and highly toxic pesticide, methyl iodide, for widespread agricultural use in California. The U.S. Environmental Protection Agency (EPA) registered methyl iodide in 2007 as a replacement for the ozone-depleting pesticide, methyl bromide. Environmental and public health advocates believe that blocking methyl iodide registration in California will prevent its use elsewhere, since the state will account for the vast majority usage and profitability nationwide. Public comments may be sent to [email protected]. If registered, methyl iodide will be used primarily to fumigate and sterilize the California’s strawberry fields, although the pesticide will also be used in nurseries and nut tree production. DPR’s proposal does not require neighbor notification before use of this extremely toxic chemical. As evidenced by California’s thriving organic industry, alternatives to fumigants exist and are in use in California. In a hearing on February 8, 2010, before the California Senate Committee on Food and Agriculture, two panels of California growers and researchers discussed a number of safe and effective alternatives to […]

(Beyond Pesticides, May 3, 2010) Researchers have found that silver nanoparticles can migrate out of fabrics that have been treated with the particles for its antibacterial properties when it is exposed to simulated perspiration, raising concerns about human exposure to nanosilver through skin absorption. This is the first study to use artificial sweat to mimic the conditions of human skin, however it is not clear if the silver materials in sweat would be absorbed through human skin. Silver has long been used as an antiseptic to reduce bacterial growth on skin, however recent advances in nanoscience (the science and manipulation of chemical and biological materials with dimensions in the range from 1-100 nanometers) led to the development of silver nanoparticles. Due to their small size, these nanoparticles are able to invade bacteria and other microorganisms and kill them, and silver nanoparticles (or nanosilver) are now widely impregnated into a wide range of consumer products, including textiles such as socks, sportswear, underwear and bedding, vacuums, washing machines, toys, sunscreens, and a host of others. The researchers tested and compared eleven different fabrics for the study, “Determination of silver nanoparticle release from antibacterial fabrics into artificial sweat” in Particle and Fibre Toxicology […]
