(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 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 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 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, April 30, 2010) The U.S. Supreme Court heard oral arguments on Tuesday in a case that prohibited Monsanto from selling genetically engineered (GE) alfalfa seed. A decision on the case of Monsanto Co. v. Geertson Seed Farms, the first time the Supreme Court has heard a case involving a genetically engineered crop, is expected in late June. The Center for Food Safety filed suit in 2006 on behalf of a coalition of organic farmers and environmental groups including Beyond Pesticides, arguing that the USDA violated the National Environmental Protection Act (NEPA) when it approved deregulation of GE alfalfa without an environmental impact statement (EIS). Roundup Ready Alfalfa is genetically engineered to resist the herbicide Glyphosate, sold by Monsanto under the trade name Roundup. Alfalfa is a bee pollinated crop used primarily for forage. The potential for cross pollination between GE and non-GE varieties of alfalfa is much higher than in other crops such as corn, because of the way Alfalfa is pollinated. In 2007, U.S. District Judge Charles Breyer ordered a moratorium on GE alfalfa until the USDA completed an EIS. The USDA released a draft EIS in December of 2009 again calling for deregulation of the crop. […]

(Beyond Pesticides, April 28, 2010) Having already requested the Scientific Committee on Consumer Safety (SCCS) to assess whether an association can be found between the use of triclosan in cosmetic products and the development of resistance by certain micro-organisms, the European Commission is launching a public consultation on the preliminary opinion, which found in March that, “ Low concentrations of triclosan can trigger the expression of resistance and cross-resistance mechanisms in bacteria in vitro”¦.[which] warrants further investigation.” The preliminary report from the SCCS, entitled “Preliminary opinion on triclosan (Antimicrobial Resistance),” was published in March 2010 and open to comment. The committee was asked to answer the question: “Does the SCCS consider a continued use of triclosan as a preservative in cosmetic products as safe taking into account the new provided documentation of resistance development by certain micro-organisms and cross-resistance?” The SCCS also found that, “Some reported environmental concentrations in a number of geographically distinct areas are high enough to suggest that such triggering of bacterial resistance could also occur in the environment. This warrants further investigation.” However, it continues, “The applications of triclosan which contribute to those high environmental concentrations cannot be properly identified nor quantified at present.” As a […]

(Beyond Pesticides, April 27, 2010) On April 22, 2010, Representative Keith Ellison (D-MN) introduced H.R.5124, legislation to prohibit the use, production, sale, importation, or exportation of any pesticide containing atrazine. The bill’s introduction coincides with an Environmental Protection Agency (EPA) Scientific Advisory Panel (SAP) meeting this week to reevaluate the human health effects of the popular endocrine disrupting herbicide. Environmentalists point to the 2003-2006 reregistration of atrazine as a prime example of the broken system of pesticide regulation in the U.S. and call on EPA to reassess atrazine fairly and for consumers to support an end to all unnecessary pesticide use by supporting organic whenever possible. “On this 40th Anniversary of Earth Day, I can think of no better tribute to our planet and our people than protecting it from known harmful chemicals,” Rep. Ellison said. “No one should ever have to worry if the water they drink is making them sick or preventing fertility.” Rep. Ellison’s bill cites widespread environmental contamination, health and environmental effects, as well as bans in other countries, as justification for the ban. The current SAP meeting follows EPA’s October 2009 announcement that it would begin a new evaluation of atrazine to determine its effects […]

(Beyond Pesticides, April 23, 2010) In recognition of the 40th anniversary of Earth Day, the Dow Chemical Company is a proud sponsor of the Dow Live Earth Run for Water. Yes, that Dow Chemical Company. The same company that manufactures some of the most hazardous pesticides in the world, that was responsible for Agent Orange, and that is liable for the worst industrial disaster of all time is sponsoring what it calls the “largest solutions-based initiative aimed at solving the global water crisis in history.” The series of events held in various cities on April 18 consisted of 6 kilometer runs, concerts and “water education activities.” The Bravo TV network will broadcast a one hour special on Friday April 23 “offering audiences an inside look at the global event and its mission to help solve the world water crisis.” When Environmental Action planned the first Earth Day in 1970 at a cost of $125,000, it accepted no money from corporations. Some 20 million Americans from across the country participated in the day’s marches, demonstrations, lectures, workshops, and other events, making it one of the most successful political events in American History. Since that time, many companies have started making donations […]

(Beyond Pesticides, April 22, 2010) In a new consumer factsheet posted April 8, 2010, the U.S. Food and Drug Administration (FDA) attempts to moderate the position it took in a February 23, 2010 letter to Congress in which it said, “[E]xisting data raise valid concerns about the effects of repetitive daily human exposure to these antiseptic ingredients” and “FDA shares your concerns over the potential effects of triclosan and triclocarban as endocrine disruptors that has emerged since we issued the TFM [Tentative Final Monograph] in 1994.” Instead, in bureaucractic-speak FDA is now saying, “[T]riclosan is not currently known to be hazardous to humans.” Safety advocates say that the FDA’s latest statement creates public confusion as the triclosan market continues to grow and manufacturers in the soap and cosmetics industry daily push misleading advertising claims about the protection from bacteria attributed to the toxic ingredient triclosan. While equivocating on the science on triclosan’s adverse effects, FDA does question the efficacy of the widely marketed triclosan products with the statement, “At this time the agency does not have evidence that triclosan in antibacterial soaps and body washes provides any benefit over washing with regular soap and water.” The new FDA factsheet, featured […]

(Beyond Pesticides, April 20, 2010) Communities from six states filed a lawsuit last month in the U.S. District Court for the Southern District of Illinois against Swiss chemical giant Syngenta AG and its American counterpart Syngenta Crop Protection, Inc., the makers of Atrazine. The 16 municipalities in the states of Kansas, Illinois, Indiana, Ohio, Missouri, and Iowa want Syngenta to pay for the expensive carbon filters needed to remove atrazine from their drinking water supply. The United States’ largest private water utility, American Water Company, has also joined the suit, representing 28 additional communities. Atrazine is used to control broad leaf weeds and annual grasses in crops, golf courses, and even residential lawns. It is used extensively for broad leaf weed control in corn. The herbicide does not cling to soil particles, but washes into surface water or leaches into groundwater, and then finds its way into municipal drinking water. It has been linked to a myriad of health problems in humans including disruption of hormone activity, birth defects, and cancer. Atrazine is also a major threat to wildlife. It harms the immune, hormone, and reproductive systems of aquatic animals. Fish and amphibians exposed to atrazine can exhibit hermaphrodism. Male […]

(Beyond Pesticides, April 19, 2010) Mississippi Governor Haley Barbour last week signed a childhood asthma management and prevention bill into law that includes provisions requiring all public school districts to implement an Integrated Pest Management (IPM) program and prohibiting the use of hazardous substances such as cleaning products and pesticides. Although the bill reads as though it will do a lot for children with asthma, with regard to the actual eliminatiion or significant reduction of toxic pesticide use at schools, the bill is weakly worded and will need strong regulations to be meaningful in protecting children from pesticide-asthma triggers. Specifically, this new law, effective July 1, 2010, requires schools to allow students to self-administer asthma and anaphylaxis medication; recommends students with asthma to have an Asthma Action Plan on file at the school; provides training for teachers, nurses, and all other school staff on asthma; requires buses to minimize idling time; requires local school health councils to adopt and support the implementation of a local school wellness policy that includes minimizing children’s exposure to pollutants that can aggravate asthma and prohibits the use of hazardous substances such as cleaning products and pesticides in and around school buildings during the hours […]

(Beyond Pesticides, April 16, 2010) Every day, children still die of malaria, a devastating disease that is both preventable and curable. In 2009, the United Nations Environment Program (UNEP) and the World Health Organization (WHO) announced a renewed international effort to combat malaria with an incremental reduction of the reliance on the synthetic pesticide DDT. However, efforts to invest in real solutions are often derailed by those promoting DDT as a “silver bullet” for malaria prevention. Tell President Obama that the President’s Malaria Initiative must invest in safe solutions to malaria, not increase reliance on DDT. Sign by April 22nd and you will be included in the petition to mark World Malaria Day. Sign the petition here. DDT, or dichloro diphenyl trichloroethane, while highly persistent in the environment, was initially found to be effective against mosquitoes and the diseases they carry, such as malaria. However, insect resistance to the chemical has been documented since 1946. DDT was banned in the U.S. in 1972 after it was linked to the decline of the bald eagle and other raptors, and it continues to be linked to health problems. A 2007 study finds that women who were exposed to DDT before the age […]

(Beyond Pesticides, April 14, 2010) A new report shows that the large-scale cultivation of genetically engineered (GE) corn is causing the spread of a new pest in the US Corn Belt. The report, “The spread of the western bean cutworm causes massive damage in the US” published by Testbiotech for Greenpeace Germany finds that GE corn plants in the U.S. that have been genetically modified to express the Bacillus thuringiensis (Bt) toxin classified as Cry1Ab are being infested by the larvae of the western bean cutworm (Striacosta albicosta). According to Testbiotech, a research based non-profit organization operating out of Germany, this new pest has been caused by the large-scale cultivation of genetically engineered plants expressing Cry1Ab such as MON810 (sold as YieldGard by company of Monsanto). The infestation has been observed since 2000, and the western bean cutworm is emerging as a new plant pest. Historically, this species of cutworm has been confined to very limited regions and did not cause any major problems in maize crops. However, for the past several years the pest has been spreading into more and more regions within the US Corn Belt causing substantial economic damage. Maize plants affected by the western bean cutworm […]

(Beyond Pesticides, April 12, 2010) Environmental, public health, labor and farmworker advocacy organizations from across the country have filed a petition asking the U.S. Environmental Protection Agency (EPA) to rescind the Bush administration era approval of the highly toxic fumigant pesticide methyl iodide in light of troubling new findings uncovered in California studies. The petition was submitted on the birthday of famed farmworker rights advocate Cesar Chavez, who drew national attention to pesticide misuse on grapes in the 1980s. “In 1988, Cesar Chavez again put his life on the line to draw attention to farmworker rights when he protested the use of pesticides with a 36-day, water-only fast,” said Jeannie Economos, Pesticide Safety and Environmental Health Project Coordinator at Farmworker Association of Florida. “Over 20 years later, we should not have to be fighting the same battles. Methyl iodide use takes us in the dead wrong direction for workers, public health and the future of agriculture.” The movement to ban methyl iodide follows the legacy of Cesar Chavez: the pesticide poses significant, direct risks to farmworkers, their families and neighboring communities. Methyl iodide is a water contaminant, nervous system poison, thyroid toxicant and is listed on California’s Proposition 65 list […]

(Beyond Pesticides, April 9, 2010) U.S. Representative Edward J. Markey (D-Mass), Chairman of the Energy and Environment Subcommittee of the Energy and Commerce Committee, yesterday called for a ban on many applications of the antimicrobial chemical triclosan ””which is found in many consumer soaps and countless other products ranging from toys to lipstick. Rep. Markey called for the ban in conjunction with the release of correspondence from the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) that raise serious concerns regarding the use of the chemical triclosan. In response to the FDA and EPA letters, Chairman Markey also announced plans to introduce legislation that will accelerate the evaluation and regulation of substances such as triclosan that may harm the human endocrine system. “Despite the fact that this chemical is found in everything from soaps to socks, there are many troubling questions about triclosan’s effectiveness and potentially harmful effects, especially for children,” said Chairman Markey. In January 2010, Chairman Markey sent letters of concern regarding triclosan to FDA and to EPA. In FDA’s response letter to Chairman Markey, the FDA stated that, “existing data raise valid concerns about the [health] effects of repetitive daily human exposure to these […]

(Beyond Pesticides, April 8, 2010) The U.S. Environmental Protection Agency (EPA) is requiring new restrictions on aluminum and magnesium phosphide products in an attempt to better protect people, especially children, from dangerous exposures. The new restrictions prohibit all uses of the products around residential areas and increase buffer zones for treatment around non-residential buildings that could be occupied by people or animals from 15 feet to 100 feet. Human exposure to these toxic chemicals, though slightly minimized, would nevertheless continue because of their continued availability for use on athletic fields and playgrounds, around non-residential buildings, and in agricultural production. Phosphide fumigants are known to be highly acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure include nausea, abdominal pain, tightness in chest, excitement, restlessness, agitation and chills. Symptoms of more severe exposure include diarrhea, cyanosis, difficulty breathing, pulmonary edema, respiratory failure, tachycardia (rapid pulse) and hypotension (low blood pressure), dizziness and/or death. Aluminum and magnesium phosphide fumigants are used primarily to control insects in stored grain and other agricultural commodities. They also are used to control burrowing rodents in outdoor agricultural and other non-domestic areas. The fumigants are restricted to use by specially trained pesticide applicators. […]

(Beyond Pesticides, April 2, 2010) On Monday, Tyrone Hayes PhD, researcher and professor at University of California Berkley gave a speech at Illinois State University urging the U.S. Environmental Protection Agency (EPA) to ban atrazine completely. Though atrazine has been the go to broad leaf weed killer for America’s corn growers since the 1950’s, evidence continues to build that atrazine is an unacceptable danger to humans and wildlife, and controversy continues as spring planting looms. In response to mounting scientific research, EPA announced last October it would review atrazine’s registration status, and last month announced plans to overhaul drinking water regulations regarding atrazine and numerous other chemicals known to harm human health. Dr. Hayes is one of the preeminent researchers on the effects of atrazine on amphibians. He compares the current loss of amphibians to the bird die-offs in the 1960’s due to DDT. The Journal Star who covered the event called the atrazine issue “one of the most contested environmental debates since PCBs were banned in the 1970s.” The debate has pitted concerned farmers, environmentalists, and human health advocates against conventional corn growers and atrazine manufacturer Syngenta. Syngenta, the Swiss chemical giant, is also facing litigation from several municipalities […]

(Beyond Pesticides, April 1, 2010) While most previous literature on melanoma has focused on host factors and sun exposure, new research shows a link between several pesticides and this deadly form of skin cancer. Epidemiologists from University of Iowa, the National Institute of Environmental Health Sciences and National Cancer Institute found that agricultural workers who apply certain pesticides to farm fields are twice as likely to contract melanoma, providing support for the hypotheses that agricultural chemicals may be another important source of skin cancer risk. The study, “Pesticide use and cutaneous melanoma in pesticide applicators in the Agricultural Heath Study” was published last month in the journal Environmental Health Perspectives. It examines cancer rates in 56,285 pesticide applicators in Iowa and North Carolina as part of the federal government’s Agricultural Health Study, a large, long-term study of pesticide applicators and their spouses. Researchers asked the pesticide applicators how often they were exposed to 50 pesticides and compared their cancer rates. Each person’s exposure was then approximated by adding up the total days that the workers had been exposed and using information from survey results on how the chemicals were applied and what protective equipment was being used. The pesticides that […]

(Beyond Pesticides, March 31, 2010) Last week the U.S. Environmental Protection Agency (EPA) announced that it was taking action aimed at improving residential safety and reducing risks associated with bug bombs, or total release foggers (TRFs). The agency is calling for significant changes to product labeling to address the most common causes of exposure incidents associated with TRFs. However, product labels do not adequately protect the public from toxic pesticide ingredients and calls to ban foggers and promote safer alternatives, action that has been urged for years both within and outside the agency, continue to go unheeded. Prompted by concerns raised by a 2009 petition from the New York City Department of Health to reclassify TRFs as restricted use pesticides, EPA sent a letter of notification to manufacturers on March 23, 2010 stating that the agency is now requiring a number of labeling changes by September 30, 2011. In spite of New York’s recommendation, the agency concluded that reclassification is inappropriate and would unnecessarily remove these inexpensive pest control tools from the residential market. Since, according to the agency’s analysis, the largest proportion of incidents is attributable to failure to follow label instructions, the changes are targeted at minimizing those […]

(Beyond Pesticides, March 30, 2010) Searching for clues to the mysterious disappearance of bees, known as “colony collapse disorder”(CCD), Penn State University researchers have identified widespread pesticide contamination of beehives. The study, “High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health,” was published March 19, 2010 in the scientific journal Public Library of Science (PLOS). The study finds 121 different types of pesticides within 887 wax, pollen, bee and hive samples from 23 states. The top 10 most frequently detected pesticides are fluvalinate, coumaphos, chlorpyrifos, chlorothalonil, amitraz, pendamethalin, endosulfan, fenpropathrin, esfenvalerate and atrazine. Miticides are the most common contaminant in the wax and bees, and fungicides are the most common contaminant of pollen. For the full results of the study, including several tables of wax, pollen and bee sample data, download the study from the PLOS website. “The pollen is not in good shape,” Chris Mullin, PhD, lead author of the study, told Discovery News. The authors state that the 98 pesticides and metabolites detected in mixtures up to 214 parts per million (ppm) in bee pollen alone represents a remarkably high level for toxicants in the brood and adult food of this primary […]

(Beyond Pesticides, March 29, 2010) Prenatal exposure to pesticides at levels that do not cause adverse health effects in the mother can lead to delayed brain developmental in the child, according to the new study, “Neurobehavioral Deficits and Increased Blood Pressure in School-Age Children Prenatally Exposed to Pesticides,” published last month in the early online edition of the journal Environmental Health Perspectives. Many pesticides are suspected of being capable of damaging the nervous system, in particular the development of a child’s brain during pregnancy and the early postnatal years of life. Now an international research team led by Philippe Grandjean, M.D., from the University of Southern Denmark and Harvard School of Public Health, has shown a delayed brain development up to two years in school children, whose mothers worked in a greenhouse during pregnancy. The exposed children also had increased blood pressure, while the mothers do not suffered adverse symptoms themselves. “The results support the notion that, in this cohort of children, prenatal exposures to pesticides are more harmful than current exposures, thereby confirming previous results of other environmental studies of neurodevelopmental toxicity and the theory of window of vulnerability of central nervous system during uterine life,” write the authors. […]

(Beyond Pesticides, March 26, 2010) A new study by researchers at Columbia University’s Mailman School of Public Health has linked exposure to the insecticide chlorpyrifos to early childhood developmental delays. Chlorpyrifos is a broad spectrum organophosphate insecticide that was banned for household use in 2001, but is still widely used in agriculture. The study, entitled “Chlorpyrifos Exposure and Urban Residential Environment Characteristics as Determinants of Early Childhood Neurodevelopment,” was published online and will be published in print in the may issue of the American Journal of Public Health. The study examined 266 children born between 1998 and 2002 living in low income neighborhoods of the South Bronx and Northern Manhattan in New York City. Before being banned chlorpyrifos was widely used in these areas. Of the children studied, 47% were male, 59% were Dominican and 41% were African American. Researchers compared motor and mental development to levels of exposure to the pesticide at birth. They found that high concentrations of chlorpyrifos in umbilical cord blood (>6.17 pg/g) corresponds to a 6.5 point decrease in the Psychomotor Development Index, and a 3.3 point decrease in the Mental development index in 3 year olds. Previous research published in 2006 on the same […]
