(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 […]

(Beyond Pesticides, January 25, 2008) Officials with the California Department of Food and Agriculture (CDFA) recently released their 2008 plan for eradicating the light brown apple moth from the Central Valley area of the state. In 2007, a state of emergency was declared to facilitate quicker action to control the moths, as CDFA reports that the infestation is spread throughout nine counties. The agency tried to disrupt the moths breeding patterns by spraying a pheremone, Checkmate LBAM-F, in several different rounds, but the problem remains. As a result, CDFA has a variety of strategies planned to wipe out the moths this year. “The primary way to eradicate this pest remains aerial spraying,” according to CDFA spokesman Steve Lyle. “The expectation is that the program will move forward with that in mind in 2008.” However, on January 22, officials said that spraying will be postponed until late spring or early summer, when a better product has been found. The United States Department of Agriculture (USDA) is currently conducting trials in New Zealand to determine which formulation is most effective against the moths. One of these forumulations would last longer than 30 days in the environment, allowing less frequent aerial applications in […]

(Beyond Pesticides, January 24, 2008) The first state bill on genetically engineered (GE) crops passed through its first committee in February, 2007, and the latest revision is scheduled for a hearing tomorrow, January 24. While AB 541 has been pared down considerably from its first and most progressive incarnation, it includes two very important measures to protect farmers whose crops are contaminated by nearby GE fields. The first provision states, “A farmer is not liable for the breach of a seed contract or for patent infringement if a product, in which the seed labeler, or patent holder or licensee, has rights, is possessed by the farmer or found on real property owned or occupied by the farmer and the presence of the product is de minimis or not intended by the farmer.” A frequent criticism of Monsanto and the company’s overwhelming market share of seed is its tendency to sue farmers who did not plant GE seed, but whose fields were contaminated by a neighbor’s GE variety. In a 2005 report by the Center for Food Safety, Executive Director Andrew Kimbrell said, “These lawsuits and settlements are nothing less than corporate extortion of American Farmers.” (See Daily News from January […]

(Beyond Pesticides, January 23, 2008) Agribusiness giants Dow AgroSciences and Monsanto have successfully persuaded the state of Minnesota to reconsider their water-quality limit for the chemical, acetochlor. Scientists representing the industry presented their own studies to the Minnesota Pollution Control Agency (MPCA) and explained that the state’s original draft limit for acetochlor was too strict. Despite three years of research conducted by the state, scientists from Dow and Monsanto presented officials at the MCPA with six published studies- one of them in Chinese- which they claimed were overlooked by the state when determining the standard for acetochlor in waterways. As a result, the MPCA has decided to allow 3.6 parts per billion of acetochlor in rivers, more than twice the concentration of the 1.7 parts per billion previously proposed. As a result, three of five streams classified as ”˜impaired’ by acetochlor, including a popular trout stream in southeastern Minnesota, can no longer be considered polluted. Some environmental advocacy groups question whether the MPCA gave favorable treatment to the pesticide makers, claiming that other research that suggest that the chemical can cause ecological damage have not been seriously considered. “It looks like there’s a double standard, that industry can come in […]

(Beyond Pesticides, January 22, 2008) Triclosan, a very common antibacterial chemical, is present in the plasma and breast milk of nursing mothers, according to a study by Swedish researchers. Every one of the 36 mothers tested positive for triclosan levels in their bodies, and the concentrations were clearly and significantly higher in the exposed group (i.e., those that use triclosan-containing products) than in the control group. This does not come as a surprise since triclosan is widely used in personal care products””including soaps, deodorants, and toothpaste””as well as plastics and textiles. Although there was high variability within groups, even members of the control group had triclosan present in their plasma, indicating that there are other significant sources of exposure outside of hygiene products. Triclosan is not removed from wastewater by conventional treatment processes and has been found in both wastewater effluent and sewage sludge. The authors of Triclosan in plasma and milk from Swedish nursing mothers and their exposure via personal care products say that the significance of the presence of triclosan in plasma and breast milk of nursing mothers is not easily deduced and that the health effects, especially the long-term effects of chronic exposure, of triclosan are not […]

(Beyond Pesticides, January 18, 2008) The second circuit federal appellate court on Thursday will hear a challenge to an EPA rule that allows people to be used as guinea pigs in tests of toxic pesticides. The lawsuit, NRDC V. EPA, was brought before the court by a coalition of environmental, farmworker and health groups in 2006. The groups contend that the agency’s human testing rule violates a law passed by Congress in 2005 mandating strict ethical and scientific protections for pesticide testing on humans. At the time, the House Committee on Government Reform found “the actual experiments being considered by EPA are deeply flawed and rife with ethical violations.” “Testing poisons on people is unethical and against the law,” said Shelley Davis, Beyond Pesticides board member and deputy director of Farmworker Justice, a national advocacy and education center for migrant and seasonal farmworkers, based in Washington, D.C. “The EPA should stop accepting these industry funded tests.” Previous human testing by industry produced serious ethical and scientific problems including one instance in which a company told participants they were eating vitamins, not toxic pesticides. In other instances citied in the lawsuit, researchers ignored the adverse health effects reported by the participants. […]

(Beyond Pesticides, January 17, 2008) Newly elected members of the Council of the District of Columbia brought the issue of reforming pesticide law to the Council yesterday in a hearing on a right-to-know bill, Pesticide Consumer Notification Amendment Act of 2007, Bill 17-493. The bill would be the first time pesticide law in the District has been amended since the law was passed in 1977. Pest control industry representatives did not oppose the bill, but urged the sponsors to shift the burden of notification of apartment building residents to the landlord. While the bill is a notification amendment that requires licensed pesticide applicators to provide hazard information to potential customers and those in multi-unit buildings who would be exposed, the bill’s sponsors throughout the hearing cited the need for overhauling the law to stop the use of hazardous pesticides in the District. The hearing was held in the Committee on Public Services and Consumer Affairs by Chairperson Mary Cheh. When told that it was working on these issues by the Department of the Environment, which oversees pesticide regulation and enforcement, the Council members said that was not good enough, and seemed unconvinced by the argument that pesticide restrictions are best […]

(Beyond Pesticides, January 16, 2008) As of January 2008, the UK’s leading campaigning and certification organization for organic food and farming bans man-made nanomaterials from all of its certified organic products. The Soil Association has become the first organization in the world to formally reject having nanomaterials in organic cosmetics, food, and textile products, and prohibits products made with nanoparticles from carrying the pro-organic group’s logo. In their press release, the association states that they are the first to take action against this hazardous, potentially toxic technology that poses a serious new threat to human health. While the group recognizes some potential benefits from nanotechnology, like its use in medicine and in the renewable energy sectors, there is insufficient evidence about the impact of nanotechnology on the environment and human health. The Soil Association Standard’s Board decided to ban manufactured nanoparticles as ingredients, in keeping with their organic standards and principles. The initiative stands at the core of the organic movement’s values of protecting human health. Soil Association policy manager, Gundula Azeez, said, “The Soil Association is the first organization in the world to ban nanoparticles. There should be no place for nanoparticles in health and beauty products or food. […]

(Beyond Pesticides, January 15, 2008) Health officials have warned that a “widespread appearance” of mosquito-born diseases like dengue fever is a real possibility in the US. The disease is already beginning to make is presence felt with cases popping up in Texas, Hawaii and Puerto Rico. Dengue, a flu-like illness that infects 50 million to 100 million people a year, has been growing more prevalent and severe as it moves from tropical regions into more temperate areas, where it’s now endemic, and along the U.S. border with Mexico. Many fear that as temperatures increase in temperate regions due to global warming, mosquitoes could extend their northern migration in North America. “It’s starting to creep up from South America to the Caribbean,” Dr. Anthony S. Fauci, head of the National Institute of Allergy and Infectious Diseases, said in an interview. “If it can occur right at the tip of Texas, a disease which maybe people never heard of could actually appear here.” Drs. David Morens and Anthony Fauci of the National Institute of Allergy and Infectious Diseases brought attention to the issue in a paper entitled Dengue and Hemorrhagic Fever: A Potential Threat to Public Health in the United States, published […]

(Beyond Pesticides, January 14, 2008) Researchers at the Indian Institute of Technology (IIT) Madras have developed nanoparticles that can remove organochlorine pesticides from drinking water. These chemicals are quite persistent in the environment and difficult to remove from water. Notorious organochlorines include DDT, endosulfan, HCH (hexacholorcyclohexane) and aldrin, all of which have known health and/or environmental hazards. Many of these chemical pesticides are used heavily in agriculture and taint India’s water. Though no comprehensive national survey has been done, isolated studies show contamination of groundwater and river systems that cannot be removed by standard water filters. “Even though some of these pesticides have been banned, they are very much present in the environment. For instance, endosulfan has an environmental lifetime of 100 years,” said Thalappil Pradeep, professor of chemistry at IIT Madras. He leads the research that has shown that nanoparticles, mostly from gold, silver, copper and several oxides, are effective at removing endosulfan even at very low concentration. “Efficient chemistry at low concentration is important so that even if one molecule of the pesticide passes by, it gets removed by the nanoparticle,” said Pradeep. He holds a US and an Indian patent and has licensed part of the technology […]

(Beyond Pesticides, January 11, 2008) Talks between the Environmental Protection Agency (EPA) and Dow Chemical Company ended unsuccessfully when EPA determined that Dow’s offers were not comprehensive enough. Negotiations had centered around study and interim cleanup measures in the Saginaw and Tittabawassee rivers, wetlands, and Saginaw Bay. Dow agreed in July to clean up dioxin contamination downstream of its Midland, Michigan facility, but this time Dow spokesman John C. Musser said, “They were asking us to go beyond what we thought was reasonable, and we could not with our earlier offers resolve that dispute.” EPA plans to return to negotiations, but the latest round was not progressing successfully. “Key issues that are paramount for protecting human health and the environment remain unsolved,” said Ralph Dollhopf, associate director for the Superfund Division of EPA’s Region 5 Office in Chicago. “EPA simply will not accept any deal that is not comprehensive.” EPA spokeswoman Anne Rowan added, “We’re not walking away from cleaning up the river system. We walked away from negotiations that we thought were not fruitful.” The state Department of Environmental Quality (DEQ) has worked with Dow to ensure completion of the required cleanup, and these latest developments seem par for […]

(Beyond Pesticides, January 10, 2007) EPA decided at the end of 2007 to extend the deadline for public comments on its controversial proposal to allow pesticide product labels with third-party endorsements and cause-marketing claims. The new due date is March 27, 2008. The agency extended the public comment period for another 90 days in response to requests from Beyond Pesticides and others. In extending the comment, Debra Edwards, Director, Office of Pesticide Programs, said, “The Agency is particularly interested in assuring that its State partners in pesticide regulations, as well as organizations such as yours, have adequate opportunity for comments.” See letter.The issue of cause-marketing on pesticide labels came up last year when Clorox petitioned EPA to allow it to display the Red Cross logo on some of its products, including pine-sol and bleach products. In letters to all the state pesticide regulatory agencies in March, 2007, Beyond Pesticides urged the states to deny the label changes approved by EPA, saying: The inherent danger is that misleading the public about pesticides can result in harm to consumers who either do not, unfortunately, take the time to read pesticide labels or who cannot read or comprehend labels (e.g. non-English speaking citizens, […]

(Beyond Pesticides, January 9, 2008) Triclocarban, an antibacterial compound widely used as an additive to a range of household and personal care products including bar soaps, detergents, body washes, cleansing lotions, and wipes, has been found to have an amplification effect on the activity of natural hormones, which in turn can lead to adverse reproductive and developmental effects. In the study, published online November 29, 2007 in Endocrinology, researchers from University of California- Davis and Yale University investigated the endocrine disrupting properties of triclocarban and other polychlorinated diphenyl urea compounds by exposing human cells and rats to levels similar to those found in people. Triclocarban was found to have a synergistic interaction with the sex hormone, testosterone- present in both males and females. This interaction produced a positive, amplified biological effect, which is likely to hyperstimulate native sex hormones. This amplification of sex hormone activity occurs at the target cell and can result in developmental defects or decreased reproductive function. Researchers further explained that ovulation and ovarian function in females can be disrupted, while sperm quality can be decreased in males. The researchers also point out that the results of their study create a new category for endocrine disruptive substances […]
