(Beyond Pesticides, February 28, 2008) Earthworms studied in agricultural fields have been found to contain chemicals from household products (including the widely marketed triclosan, a hazardous antimicrobial) and manure, indicating that such substances are entering the food chain. U.S. Geological Survey (USGS) Scientists and their colleague from Colorado State University at Pueblo published their findings in Environmental Science and Technology. The study results demonstrate that organic chemicals introduced to the environment via land application of biosolids, the solid byproduct of wastewater treatment, and manure as fertilizers are transferred to earthworms. Earthworms continuously ingest soils for nourishment and can accumulate the chemicals present in the soil.The scientists collected soil and earthworms from three agricultural fields””a soybean field fertilized with biosolids, a corn field fertilized with swine manure, and a soybean field that had received no applications of either biosolids or manure for at least 7 years. The chemicals investigated are considered indicators of human and animal waste sources and include a range of active ingredients in common household products such as detergents, antibacterial soaps, fragrances, and pharmaceuticals. All of these chemicals tend to be concentrated in the municipal waste distribution and disposal process and are referred to as anthropogenic waste indicators […]

(Beyond Pesticides, February 27, 2008) EPA is seeking public comments on a proposed list of 104 possible drinking water contaminants that may need to be regulated in the future to ensure the continued protection of drinking water. Under the Safe Drinking Water Act, EPA includes on the draft Contaminant Candidate List (CCL) currently unregulated contaminants that are known or anticipated to occur in public water systems and which may require regulation. This draft CCL, which is the third such listing, lists 93 chemical contaminants or groups and 11 microbes, and describes the process and basis for selecting these contaminants.“EPA is casting a broader scientific net for potential regulation of chemicals and microbes in drinking water,” said Assistant Administrator for Water Benjamin H. Grumbles. “EPA’s proposed list of priority contaminants will advance sound science and public health by targeting research on certain chemicals and microbes and informing regulators on how best to reduce risk.” The CCL process was established by the 1996 amendments to the Safe Drinking Water Act as a mechanism to determine if new regulations are needed to protect drinking water. Under this process EPA conducted extensive research into the occurrence and health effects of the listed contaminants before […]

(Beyond Pesticides, February 26, 2008) The United Farm Workers of America, Beyond Pesticides and others, represented by lawyers from Earthjustice, argued in federal court that the Environmental Protection Agency’s (EPA) decision to allow the use of azinphos-methyl until 2012 was unconscionable. The plaintiffs say EPA did not consider harm to farmworkers and their families, or to rivers, lakes and salmon, and the agency should be forced to reconsider. “There are workers getting sick,” Patti Goldman, a lawyer for Earthjustice, told U.S. District Judge Ricardo S. Martinez. “This isn’t just hypothetical. There are workers being taken out of the field.”The AP reports that Cynthia Morris, a Justice Department lawyer who argued on the agency’s behalf, told the judge that the short-term benefits of allowing growers to keep using AZM for the next several years outweigh the potential harm. She argued that the agency’s decision was reasonable, and failed to meet the “arbitrary and capricious” standard for the judge to undo it.In November 2006, EPA decided that AZM poses unreasonable adverse effects and must be banned but allowed its continued use on fruit crops for six more years — until 2012 — and on nut crops for three more years — until […]

(Beyond Pesticides, February 25, 2008) After two years of residents calling on local authorities for greater protection from drifting airborne pesticides, the Tulare County Agricultural Commissioner has adopted new pesticide buffer zone rules, or “permit conditions,” that prohibits aerial applications of restricted use pesticides within one-quarter mile of schools in session or due to be in session within 24 hours, occupied farm labor camps and residential areas. The Allensworth School Board, the Cutler-Orosi School Board and over 1,750 organizations and individuals endorsed the call for buffer zones in Tulare County. Community members launched efforts to establish buffer zones because of the serious health risks posed by pesticide exposure, ranging from short-term effects such as dizziness, vomiting and rashes to long-term effects including asthma, cancer, birth defects, damage to the developing child and neurological harm. Community efforts included conducting surveys documenting the general public’s exposure to pesticides, sampling for pesticides in the air and in residents’ bodies, and presenting local authorities with a petition endorsing the establishment of buffer zones around sensitive sites such as schools. According to the Mercury News, “An Associated Press investigation found that 590 people in California were sickened by pesticides at schools from 1996 to 2005, […]

(Beyond Pesticides, February 22, 2008) The California Department of Food and Agriculture (CDFA) has released its latest schedule for assault on the light brown apple moth (LBAM), adding specifics to its previous outline of the 2008 plan. As has been previously reported, public outcry against the aerial spraying of a pheromone mixture has been widespread, in spite of the state’s insistence on the necessity of such measures. As a result, two state senators are introducing measures to stop, or at least postpone, spraying until safety and efficacy can be assured. The latest schedule from CDFA identifies anticipated components to the eradication effort. For instance, twist-ties (carrying the moths’ pheromone) will be applied to trees beginning February 25, which will be used alone in areas of low infestation, and “to complement mating disruption treatments against heaviest populations.” They will remain in place until an area is free from moths for two life-cycles. “Pheromone male moth attractant treatment,” applied to utility poles and trees, both on public and private property, will occur in areas of mid-level infestation, measuring at least 3,000 male moths per square mile. These applications will begin in April, and in areas of heaviest infestation, will precede aerial spraying. […]

(Beyond Pesticides, February 21, 2008) The Simpson Timber Company, in a settlement with two environmental groups, has agreed to remove tons of sediment laden with cancer-causing dioxin from a contaminated ditch that empties into Humboldt Bay, California’s second largest natural bay.The timber company was sued in 2006 by the two Eureka-based environmental groups, Humboldt Baykeeper and Californians for Alternatives to Toxics (CATs). Tests were conducted, and dioxin was found at levels tens of thousands of times higher than Environmental Protection Agency (EPA) standards, some of the highest levels found in the nation. The test sites were near where Simpson commonly sprayed plywood with the now-widely-banned wood preservative pentachlorophenol in the 1960’s. Further indications that dioxin, which is one of the most potent carcinogens known, had persisted in the environment came last year when the State Water Resources Control Board listed Humboldt Bay as “impaired” after dioxin was found in the tissues of local fish and oysters. Under the settlement, Simpson is required to dig up contaminated sediment in the ditch, which is adjacent to Humboldt Bay’s only public fishing pier, and haul it to a licensed disposal site. The company also must restore the ditch as a functioning wetland and […]

(Beyond Pesticides, February 20, 2008) Pesticides that run off agricultural land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system, according to researcher Nathaniel Scholz, PhD, a zoologist with the National Oceanic and Atmospheric Administration (NOAA) in Seattle. Dr. Scholz, who presented his findings at the symposium entitled From Kitchen Sinks to Ocean Basins: Emerging Chemical Contaminants and Human Health,  which was organized by NOAA and hosted at the American Association for the Advancement of Science (AAAS) Annual Meeting, had previously looked at the effects of individual pesticides. However, to get a more realistic idea of exposure, combinations of several pesticides were used and juvenile salmon exposed to them two at a time. The results surprised Dr. Scholz and his team. The total impact observed from combined pesticides was greater than the sum of the individual pesticides, demonstrating a synergistic effect. Some pesticides that were not deadly when tested in individual trials killed all salmon exposed to combinations. A mixture of the pesticides diazinon and malathion, exhibited the greatest synergistic effect and killed all the salmon exposed to them, even at the lowest concentrations. “It was eye opening,” Dr. […]

(Beyond Pesticides, February 19, 2008) Common household chemicals and widespread pollutants are changing male reproductive health and impacting sexual function, development and cancer rates of today’s generations and possibly their offspring, according to more than 15 years of research by a Colorado State University expert. For example, one study looking at sperm counts globally from 1940, when chemicals first began to be widely produced, to the 1990s, indicates a 1.15 percent per year decline in sperm counts. These declines may be linked to chemical exposure.Rao Veeramachaneni, BVSc, MScVet, PhD, a biomedical sciences professor in the College of Veterinary Medicine and Biomedical Sciences, has found that chemicals including pesticides, common pollutants in ground water, and chemicals in plastics, make-up and nail polish are on a growing list of culprits causing developmental abnormalities such as impaired sperm quality and impotence. Reproductive health can be compromised if males are exposed at various times in life spanning from in utero up to adulthood.Dr. Veeramachaneni’s findings span the globe and are across species lines, from humans to horses, wildlife to frogs. His research, coupled with the collective findings of other experts in the field, indicates a strong link related to pollutants, and incidence of such […]

(Beyond Pesticides, February 15, 2008) Two studies have just been released, one by the International Service for the Acquisition of Agri-Biotech Applications (ISAAA), a promoter of genetically-engineering crops,  and the other by the Center for Food Safety (CFS) and Friends of the Earth, each with differing conclusions on the impact of genetically engineered (GE) crops on the health of our food systems. The debate is one that has existed for years, particularly as GE seeds have spread worldwide, now accounting for 280 million acres of cropland in 23 countries. Reports have historically provided significant documentation of herbicide-resistant weeds developing as a result of heavy reliance on the chemicals crops are bred to tolerate. Insect resistance has also been recently discovered. Legislators have recognized the need to protect farmers from GE contamination and resulting lawsuits from seed developer Monsanto. Concerns over a litany of health and environmental risks from GE crops continue. The timing of these two studies highlights the disparity between how the GE industry represents its product and how public interest groups evaluate the effects and risks they see to farmers and consumers alike. The ISAAA study, entitled Global Status of Commercialized Biotech/GM Crops: 2007, celebrates the first twelve […]

(Beyond Pesticides, February 14, 2008) Researchers have found what they are calling the first insect resistance in the field to genetically engineered plants that are modified to produce an insecticide called Bacillus thuringiensis, or Bt. The University of Arizona (UA) researchers, who have previously received research support from Monsanto and Cotton, Inc., are supportive of bioengineered crops and dismiss the findings of resistance, given that they are only in cotton and no other crops. The report, “Insect resistance to Bt crops: evidence versus theory,” is due out in the February issue of Nature. Concern about resistance has raised fears in the organic community that Bt, derived from natural soil bacterium, would be rendered ineffective as insect resistance spreads and this natural control collapses over time.In organic systems, composted manures and cover crops replace synthetic fertilizers, innovative weeding strategies are used instead of herbicides, beneficial insects and trap crops control insect pests, and alternatives to toxic defoliants prepare plants for harvest. Bt-resistant populations of the insect bollworm, Helicoverpa zea, were found in more than a dozen crop fields in Mississippi and Arkansas between 2003 and 2006. The bollworm resistance to Bt cotton was discovered when a team of University of Arizona […]

(Beyond Pesticides, February 13, 2008) The publication of a federal study undertaken by the Centers for Disease and Control (CDC) has been blocked for more than seven months because it contains “alarming information” of evidence of elevated infant mortality and cancer rates in the region surrounding the Great Lakes.The report entitled, Public Health Implications of Hazardous Substances in the Twenty-Six U.S. Great Lakes Areas of Concern, was commissioned by the International Joint Commission (IJC), an independent organization that advises the U.S. and Canadian governments on the use and quality of boundary waters between the two countries, and compiled by the CDC’s Agency for Toxic Substances and Disease Registry (ATSDR). The report outlines the “areas of concern” in which more than nine million people in major metropolitan areas as Chicago, Cleveland, Detroit, and Milwaukee, face higher health risks from exposure to dioxin, PCBs, pesticides, lead, mercury, or six other hazardous pollutants.Contributors to the report include senior experts from the Environmental Protection Agency, CDC, universities, as well as federal and state researchers. These experts have been reviewing data since 2004 and have found low birth weights, elevated rates of infant mortality and premature births, and elevated death rates from breast cancer, colon […]

(Beyond Pesticides, February 11, 2008) Growing out of concern from pesticides drifting onto school grounds, the Hawaii Senate has begun looking at adopting legislation that would better protect students and staff from nearby pesticide applications.The bill, SB 3170, will establish a 1,500 foot no-spray buffer zone for all backpack applications and a half-mile buffer zone for all aerial applications around all elementary schools. It will also require a 72-hour prior written notification to all schools in the immediate area of a pesticide application as well as a one-week prior notification of all commercial use of pesticides within a five-mile radius of any school or educational institution property to the Department of Education (DOE). DOE will then notify the appropriate schools within 72-hours of the proposed application. The bill’s author, Senate Majority Leader Gary Hooser, stated on his website, “A pesticide is poison. It is designed to kill. No child should be subjected to it, especially in a learning environment. To allow it doesn’t even make sense.” Many of those that spoke at the public hearing on the bill on February 4th had been impacted by the type applications the bill is trying to prevent. Kauai’s Garden Island Newspaper states that […]

(Beyond Pesticides, February 8, 2008) The Environmental Protection Agency (EPA) is asking for public input on its review of the chemical endosulfan, an antiquated and dangerous insecticide. Now is the time to go on record to protect children, farmworkers and rural communities from this harmful nerve toxin. Used in the U.S. on tomatoes, cotton and other crops, endosulfan harms the hormone system, and low levels of exposure in the womb have been linked to autism, male reproductive harm, and other birth defects. Acute poisoning can cause headaches, nausea, vomiting, convulsions, and in extreme cases, unconsciousness and even death. EPA’s own analysis shows that endosulfan endangers workers who handle it directly and those who work in endosulfan-treated fields. Endosulfan travels great distances, accumulates up the food chain, and poses grave risks to aquatic ecosystems. The European Union and several other countries have already banned endosulfan, and alternatives are available. It’s time the U.S. does its part to protect communities and the environment at home and around the world from this persistent organic pollutant. TAKE ACTION: Let EPA know that continued use of this unnecessary poison is unacceptable. Add your name to the petition today and forward to as many people as […]

(Beyond Pesticides, February 7, 2008) The U.S. Environmental Protection Agency (EPA) has awarded more than $500,000 in federal grant funds to several states and non-profit organizations to be used for programs to educate health care providers and women of childbearing age on environmental health risks.The grants were provided to five states and non-profit organizations in Ohio, Michigan, Oregon, Florida, and Texas, and are to focus on educating women, especially pregnant women, on the hazards of environmental contaminants and hazards to children. Health issues such as exposure to mercury, lead, environmental tobacco smoke, chemicals, pesticides, drinking water contaminants, and indoor and outdoor air contaminants have been especially targeted. These grants are estimated to benefit 3,000 health care providers and 10,000 women of childbearing age.“We’re giving pregnant women information on how to avoid exposure to certain environmental hazards to give children a healthy start to life,” said Dona Deleon, acting director, Office of Children’s Health Protection and Environmental Education. “These grants help the public health community reach women during this important time in their lives.”According to the EPA, pregnancy is a time for joy and celebration, but it is also a time to be especially careful about the environment in which one […]

(Beyond Pesticides, February 6, 2008) EPA has submitted a draft Notice of Intent to Cancel (NOIC) for all carbofuran registrations to EPA’s Scientific Advisory Panel (SAP). Carbofuran is a highly toxic insecticide used on field, fruit and vegetable crops and has long been the subject of controversy and a series of use restrictions that environmentalists have decried as too limited. EPA has opened a docket containing the materials provided to the SAP that is convening on February 5-8. The SAP will review the scientific assessment underlying EPA’s NOIC for carbofuran and respond to questions posed by the agency related to the impact on health and the environment of the proposal. The docket number is EPA-HQ-OPP-2007-1088; view docket information.This action is the result of an interim reregistration eligibility decision reached by EPA in August 2006, in which the agency found all products containing carbofuran ineligible for reregistration. FIFRA requires that EPA consult the SAP before issuing an NOIC. The SAP meeting, which is open to the public, will be held at an EPA Office of Pesticide Programs conference room at One Potomac Yard in Arlington, Virginia.Carbofuran was first registered in the United States in 1969 and is classified as a restricted […]

(Beyond Pesticides, February 5, 2008) Whether you love it or hate it, Valentine’s Day is less than ten days away. Millions of flowers and chocolates will soon be bought and given to loved ones. Unfortunately, these gifts come at a cost much higher than the one on the price tag. Conventional roses and chocolate sold in the United States are produced using toxic pesticides, with little regard for the workers or the environment.The United States imports about 70 percent of its flowers from foreign countries, mostly from Ecuador and Columbia. Roses analyzed in the past few years were found to contain a myriad of harmful pesticides that ranged from organophosphates such as Dimethoate, carbamate- Aldicarb, to organochlorines like Captan, Bravo, Tedion, Iprodione and Procymidone. Organophosphates are considered to be the most likely pesticide to cause an acute poisoning. They are a highly toxic class of pesticides that affect the central nervous, cardiovascular and respiratory systems. Symptoms of exposure include: numbness, tingling sensations, headache, dizziness, tremors, nausea, abdominal cramps, sweating, incoordination, blurred vision, difficulty breathing, slow heartbeat, unconsciousness, incontinence, convulsions and fatality. Some organophosphates have been linked to birth defects and cancer. Organochlorines are known estrogenic pesticides and have been linked […]

(Beyond Pesticides, February 4, 2008) Following on the recommendation of a California Legislature-supported report in 2006, a new report (January 17, 2008) prepared by the University of California, Berkeley and UCLA, reinforces the earlier call for a statewide initiative to adopt comprehensive efforts to eliminate hazardous chemical use and reduce billions of dollars of associated costs from pollution and chemical-related diseases. The report, Green Chemistry: Cornerstone to a Sustainable California, calls on California to lead the nation in implementing a comprehensive approach to the management of chemicals and products.Policy recommendations include: (i) Passing new laws to remedy the insufficient data available on the toxicity of chemicals so California businesses, regulators and consumers can make informed choices about the products they use; (ii) Providing California agencies with a new legal framework to enable them to act when there are reasonable concerns about a product’s safety, even when complete hazard or tracking data are unavailable; and (iv) Investing in the design of chemicals, materials and manufacturing processes that are inherently safer for humans.Some of these recommendations echo the 2006 UC report to the California Legislature on green chemistry policy, which contributed to the introduction of new state legislation in 2007 to require […]

(Beyond Pesticides, February 1, 2008) Two studies of nutrient levels in the Gulf of Mexico, one by the United States Geological Survey and the other by Yale and Louisiana State University researchers, have recently been published. Both reveal that nutrient levels in the Mississippi watershed have risen significantly, and that the growing “dead zone” in the Gulf can largely be attributed to changes in agricultural practices in the last half-century. The first report, entitled “Differences in Phosphorus and Nitrogen Delivery to The Gulf of Mexico from the Mississippi River Basin,” modeled nutrient delivery to the gulf in order to determine the watershed management practices required to reduce nitrogen discharge by 30 to 45 percent, and the size of the dead zone in half, by 2015. 13 states in the midwest contributed the overwhelming majority of inputs to the watershed. The largest contributor to nitrogen pollution of the watershed came from corn and soybean production, which also contributed to a quarter of the total phosphorus runoff into the Gulf. The researchers concluded that future management strategies must “include recognition of important differences in the agricultural sources of N[itrogen] and P[hosphorus] . . . and better control of both N and P […]

(Beyond Pesticides, January 31, 2008) A study to be published in the February 2008 issue of Environmental Health Perspectives finds that children who eat a conventional diet of food produced with chemical-intensive practices carry residues of organophosate pesticides that are reduced or eliminated when they switch to an organic diet. The study is entitled “Dietary Intake and Its Contribution to Longitudinal Organophosphorus Pesticide Exposure in Urban/Suburban Children” (Chensheng Lu, Dana B. Barr, Melanie A. Pearson, and Lance A. Waller) and includes authors from Rollins School of Public Health, Emory University, and the National Center for Environmental Health, Centers for Disease Control and Prevention.According to the authors, “The objective of this article is to present the data of assessing young urban/suburban children’s longitudinal exposure to OP [organophosphate] pesticides in a group [of] young children participating in the Children Pesticide Exposure Study (CPES). The results from this study identify not only the predominant source of OP pesticide exposure but also the profile of exposures in children that are vital in formulating the strategies, both from the regulatory policy and personal behavior change perspectives, in reducing children’s exposures to OP pesticides.” The study design included 23 children, male and female, from the Seattle […]

(Beyond Pesticides, January 30, 2008) A survey of 31 Australian strawberry growers conducted by a consumer watchdog revealed that almost all conventionally grown strawberries contained residues of pesticides. Several samples of the strawberries tested contained pesticide residues that exceeded the legal limit, and some even tested positive for pesticides banned for use on strawberries.Tests revealed that that 17 of the 27 samples of conventionally grown strawberries registered residues of at least two types of pesticide or fungicide. Four samples had traces of four different chemicals on the skin that had penetrated the fruit’s flesh as well. Choice, the chemical watchdog group that commissioned the survey, described the findings as alarming and calls on the Australian Government to remedy years of neglect over pesticide regulation, and to require independent, mandatory testing of all fruits and vegetables. “Analysis shows strawberries are more likely to have pesticide residues than other fresh fruit, and washing does not necessarily remove them,” said Choice spokesman Christopher Zinn. “Strawberries contain lots of nutrients but unfortunately they also tend to contain residues of pesticide”¦ [T]here are some concerns about long-term exposure to a mixture of different pesticides.” Jo Immig, the coordinator of National Toxics Network Inc, said the […]

(Beyond Pesticides, January 29, 2008) University of Cambridge scientists say there may be a link between persistent organic pollutants (POPs), including pesticides, and Type 2 Diabetes. The Cambridge scientists are advocating additional research into the little understood links between environmental pollution and adult onset diabetes. In the most recent edition of the journal Lancet, Oliver Jones, Ph.D., and Julian Griffin, Ph.D., highlight the need to research the possible link between persistent organic pollutants (POPs, a group which includes many pesticides) and insulin resistance, which can lead to adult onset diabetes. In their commentary, Dr. Jones and Dr. Griffin cite peer reviewed research including that of D. Lee, et al, which demonstrated a very strong relationship between the levels of POPs in blood, particularly organochlorine compounds, and the risk of type 2 diabetes. “Of course correlation does not automatically imply causation,” says Dr. Jones. “But if there is indeed a link, the health implications could be tremendous. At present there is very limited information. Research into adult onset diabetes currently focuses on genetics and obesity; there has been almost no consideration for the possible influence of environmental factors such as pollution.” Interestingly, in the Lee study an association between obesity and […]
