(Beyond Pesticides, August 12, 2010) In an effort to convince NStar Electric and Gas Corporation to stop using herbicides on rights-of-way, like-minded environmental activists, citizen groups and business owners formed a coalition on Cape Cod: “Cape Cod for a Truly Green NSTAR.” Due to the increased pressure from local activists and residents, NStar made an agreement with regionally planning authority, Cape Cod Commission to postpone the use of herbicides on rights-of-way until 2011. The Commission reasoned that with more time, Cape towns could develop maps to identify areas and drinking water supplies more sensitive to herbicide use. Several organizations and business have signed on to the coalition in support of a ban on herbicides along rights-of-way, such as Clean Water Action, Cape Cod Organic Gardeners, the Massachusetts Breast Cancer Coalition, and the Sierra Club (see the full list online). Ever since NStar started using herbicides in 2004, local residents have worried about potential contamination of the Cape’s underground drinking water supply. Even though NStar has a “green” commitment statement on its website, pledging to lessen impacts to the environment as much as possible, the coalition argues that the company’s use of herbicides on rights-of-way violates this promise. NStar representative Michael […]

(Beyond Pesticides, August 10, 2010) Senator Blanche Lincoln (D-AR), Chair of the Senate Committee on Agriculture, Nutrition, and Forestry, and Ranking Member Saxby Chambliss (R-GA) introduced legislation on August 6, 2010 that would strip the public of the protection provided by the Clean Water Act (CWA) from the toxic hazards of pesticides applied to or near U.S. waterways. If successful, the bill, S. 3735, would nullify regulations that require pesticide applicators apply for National Pollutant Discharge Elimination System (NPDES) permits under CWA before applying pesticides on or near surface waters. Beyond Pesticides encourages its members to contact their Senators and let them know how they feel about S. 3735. Senators Lincoln and Chambliss say that because pesticides are registered under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) additional regulation is unnecessary and the legislation will reduce the burden on farmers, foresters and ranchers. Environmentalists argue that CWA is more protective, and pesticides should be regulated under both statues to improve protections for human health and the environment. CWA uses a health-based standard known as maximum contamination levels to protect waterways and requires permits when chemicals are directly deposited into rivers, lakes and streams, while FIFRA uses a highly subjective […]

(Beyond Pesticides, August 9, 2010) Two separate findings that showcase increased exposure and potential for exposure in humans to the toxic chemical triclosan add to the mounting evidence that the non-medical use of this chemical should be banned. Newly released data from the Centers for Disease Control and Prevention (CDC) finds that levels of triclosan in humans have increased by 50% since 2004. Moreover, a study by the University of Toledo shows that triclosan and triclocarbon, a similar compound, can enter the food chain through use of contaminated water or fertilizer on agricultural crops. CDC’s updated National Report on Human Exposure to Environmental Chemicals finds that the 50% increase in levels of triclosan is across all demographics in the U.S. population. Data was collected on the concentration of triclosan in urine. Affluent people and those over the age of 20 have the highest concentrations of triclosan in their urine. The study released by the University of Toledo, “Uptake of Pharmaceutical and Personal Care Products by Soybean Plants from Soils Applied with Biosolids and Irrigated with Contaminated Water,” examines the potential for crops to take up contaminants such as triclosan from water or fertilizer. Conventional crops are often fertilized with sewage […]

(Beyond Pesticides, August 4, 2010) Several coastal towns in Maine, concerned about water contamination and the potential for the effects on aquatic life, have adopted restrictions on lawn chemicals. Pesticide opponents praise towns for cutting back on pesticide use but say that a ban on private use would make a bigger difference. Ogunquit is among the growing number of Maine towns that are restricting the use of lawn chemicals from municipal property because of environmental and public health concerns. About two dozen other communities have adopted some form of pesticide limits, including Brunswick, Castine and Harpswell. There are common traits among the towns that are limiting pesticides. They tend to have affluent residents that do more lawn care applications employing lawn care companies. Mike Horn, chair of Ogunquit’s Conservation Commission, helped to guide the pesticide restriction to passage at last year’s town meeting. Mr. Horn is worried about lawn chemicals such as phoshorous and nitrogen running downhill during rain. “What is going to happen if this level of pesticides just continues to rise and people’s lawns are just running, you’re just putting a big nail in Mother’s nature’s foot,” said Mr. Horn. He added that by protecting the environment, the […]

(Beyond Pesticides, July 30, 2010) Adding to a campaign that Beyond Pesticides launched in 2004 to alert the public and pressure government to restrict the highly toxic antibacterial chemical triclosan -commonly found in antibacterial soaps and household and consumer products, the Natural Resources Defense Council (NRDC) filed a lawsuit earlier this week against the Food and Drug Administration (FDA) for failing to issue a final rule regulating the chemical. The lawsuit follows on the heels of two petitions filed by Beyond Pesticides and Food and Water Watch in 2009 and 2010 with FDA and the U.S. Environmental Protection Agency (EPA), respectively, to ban the chemical. Because of the widespread poisoning and environmental contamination caused by triclosan, the petitions cite numerous violations of statutory duties under the Federal Food, Drug and Cosmetics Act, Federal Insecticide, Fungicide, and Rodenticide Act, Clean Water Act, Safe Drinking Water Act, and Endangered Species Act. The NRDC lawsuit adds yet another dimension to the legal violations involving agency malfeasance on triclosan by asking the court to impose a strict deadline for FDA to finalize a proposed rule that has been pending for 32 years and could ban many uses of triclosan and its chemical cousin triclocarban.

(Beyond Pesticides, July 27, 2010) Groups filed a lawsuit in federal court to force the Environmental Protection Agency (EPA) to decide whether or not it will cancel all remaining uses and tolerances for the pesticide chlorpyrifos, which has been banned for residential use, but continues to expose farmworkers and consumers through its use in agriculture. In September 2007, the Natural Resources Defense Council (NRDC) and Pesticide Action Network North America (PANNA) filed a petition with EPA asking the agency to ban chlorpyrifos. In the nearly three years since, the agency has not responded. NRDC and PANNA v. EPA, filed by the nonprofit environmental law firm Earthjustice on July 22, 2010, would force EPA to make a decision on the pesticide’s ban. “This dangerous pesticide has no place in our fields, near our children, or on our food,” said Earthjustice attorney Kevin Regan. “We’re asking a court to rule so that EPA will finish the job and ban this poison.” According to Beyond Pesticides, EPA’s 2000 negotiated settlement with Dow AgroSciences, which allows the highest volume chlorpyrifos uses to continue, represents a classic failure of the risk assessment process (including the so-called cumulative risk assessment which accounts for all chemicals with […]

(Beyond Pesticides, July 23, 2010) A new study published in BioMed’s online journal, Environmental Health, links endocrine disrupting pesticides and other chemicals in household cleaning products to an elevated risk of breast cancer. Researchers at the Silent Spring Institute in Newton, MA and Boston University found that women who use household cleaners more often have double the risk of breast cancer, compared to women who use household cleaners less frequently. The study includes over 1,500 women selected from Cape Cod, MA and found a correlation between cases of breast cancer and the number of women who reported using household cleaners, particularly solid, slow-release air fresheners when used more than seven times a year, and mold removers when used more than once a week. The antimicrobials, phthalates and alkylphenolic surfactants often found in mold and mildew products are associated with various health and environmental issues. The antimicrobial triclosan for example, can cause skin irritation, allergy susceptibility, bacterial and compounded antibiotic resistance, and dioxin that jeopardizes fragile aquatic ecosystems. The study highlights methylene chloride (in some fabric cleaners), nitrobenzene (soaps, polishes), perfluorinated compounds (stainresistant, waterproof coatings), phthalates (surfactants), alkylphenols (solvents), parabens (preservatives), triclosan, and polycyclic musks (fragrance) as ingredients of concern. Past […]

(Beyond Pesticides, July 13, 2010) Beyond Pesticides is urging the public to send comments by July 19, 2010 to the Environmental Protection Agency (EPA) on its recently issued draft “general permit” under the Clean Water Act (CWA) that will govern aquatic pesticides and certain pesticide spraying over or near surface waters, including mosquito spraying and spraying over forest canopies and near irrigation ditches. Environmental groups believe the pesticide industry is lobbying to make this permit as weak as possible. Beyond Pesticides encourages individuals to send comments to EPA supporting strong, meaningful regulation of pesticide applications in order to fully protect public health and the environment. See talking points and instructions for sending comments below. Background EPA announced the public availability of a draft National Pollutant Discharge Elimination System (NPDES) General Permit, posted here, for certain pesticide use patterns, also known as the Pesticides General Permit (PGP) on June 2, 2010. The action stems from a 2009 court decision in the case of the National Cotton Council et al. v. EPA, in which the 6th circuit court of appeals ruled that pesticide discharges into water are pollutants and require permitting under the CWA. This ruling overturned the Bush administration policy that […]

(Beyond Pesticides, June 30, 2010) The U.S. Environmental Protection Agency (EPA) approval process for thousands of antimicrobial products is woefully inadequate, according Public Employees for Environmental Responsibility (PEER). Despite a growing body of scientific evidence about the side-effects of these products, EPA rubberstamps registrations without duly considering an array of potential public health and environmental impacts. Antimicrobials are now a billion dollar business with more than 5,000 such products currently registered with EPA. Initially designed for hospitals and clinics, antimicrobial pesticides are today found in products ranging from household cleaners to mattresses and bedding, cosmetics, toys, toothpaste and even chopsticks. Antibacterial products are being marketed to the health conscious without firm evidence of real benefits and amid growing concern about downstream consequences. One prime example of this is the antibacterial pesticide triclosan that is formulated into hundreds of personal care products, toys and textiles. Studies show that triclosan is an endocrine disruptor, accumulates in human fatty tissue and can influence the onset of bacterial resistance. Beyond Pesticides, Food and Water Watch and several other groups petitioned FDA in 2009 and EPA in January 2010, calling for the ban of triclosan citing the possibility of bacterial resistance to antibacterial substances and […]

(Beyond Pesticides, June 24, 2010) Our food purchases have a direct effect on the health of our environment and those who grow and harvest what we eat. Beyond Pesticides launched its Organic Food: Eating with a Conscience guide, which shows consumers why, according to the group, “food labeled organic is the right choice.” Jay Feldman, executive director of Beyond Pesticides, said, “In addition to serious health questions linked to actual residues of toxic pesticides on the food we eat, our food buying decisions support or reject hazardous agricultural practices, protection of farmworkers, and stewardship of the earth.” The Eating with a Conscience guide explains to consumers the effect they are having on health and the environment when they purchase food grown with chemical-intensive methods, even if a large number of residues do not remain on the finished food product. The group points to USDA organic certification as “the only system of food labeling that is subject to independent public review and oversight, assuring consumers that toxic, synthetic pesticides used in conventional agriculture are replaced by management practices focused on soil biology, biodiversity, and plant health.” “Organic practices under the Organic Foods Production Act eliminate commonly used toxic chemicals in the […]

(Beyond Pesticides, June 22, 2010) The U.S. Environmental Protection Agency (EPA) announced earlier this month that it is seeking public comment on its draft five-year strategic plan, which the agency says will help advance Administrator Lisa P. Jackson’s priorities and EPA’s overall mission to protect human health and the environment. Administrator Jackson’s seven priorities are; taking action on climate change, improving air quality, protecting Americas waters, cleaning up our communities, assuring the safety of chemicals, expanding the conversation on environmentalism and working for environmental justice, and building strong state and tribal partnerships. In accordance with the Government Performance and Results Act of 1993 (GPRA), EPA submitted the agency’s 2006-2011 Strategic Plan to Congress on September 29, 2006. Now, the agency is releasing its Draft FY 2011-2015 Strategic Plan for public review and comment through July 30, 2010. GPRA requires agencies to develop a five-year Strategic Plan for what they intend to accomplish, measure how well they are doing, make appropriate decisions based on the information they have gathered, and communicate information about their performance to Congress and to the public. It includes a mission statement and sets out long-term goals and objectives; Annual Performance Plans, which provide annual performance commitments […]

(Beyond Pesticides, June 14, 2010) Whole Foods Market is setting a good example for other retailers to follow in protecting consumers from fraudulent “organic” claims on health and beauty products. The national grocery retailer of natural and organic products announced earlier this month that all cosmetic and personal care products sold at their stores with the word “organic” on the product label must comply with the U.S. Department of Agriculture (USDA) National Organic Program (NOP) or NSF 305 standards, meaning that the product must be third-party certified to USDA organic standards or front label “organic” claims must cease, according to the Organic Consumers Association. Thought the term “organic” on all products, whether for food or non-food items, meant that it was certified? That’s the law, but sometimes not the reality. The reality is that the USDA’s NOP requires certification for all “organic” claims on food products, but does not currently have similar certification requirements in place for non-food items. The new Whole Foods Market policy states, “We believe that the ‘organic’ claim used on personal care products should have very similar meaning to the ‘organic’ claim used on food products, which is currently regulated by the USDA’s National Organic Program.

(Beyond Pesticides, June 8, 2010) An Indian court in Bhopal, India, capital of Madhya Pradesh, found chemical company Union Carbide guilty of negligence and convicted eight former senior employees for their role in the world’s worst industrial disaster that killed thousands. The verdict came 25 years after the Union Carbide gas-leak and included a sentence that many victims of the accident protested was too light. According to Reuters, the defendants were charged with “death by negligence” and sentenced for two years in prison and a fine of 100,000 rupees ($2,175). The court also fined the former Indian unit of Union Carbide 500,000 rupees ($10,600). The Central Board of Investigation initially charged 12 defendants with culpable homicide, which would have carried a sentence of up to 10 years, but the Indian Supreme Court reduced these charges in 1996. Many victims and activists found the light sentence, “an insult”, and Sandhna Kamik of the Bhopal Gas Victims Struggle group protested, “Even with the guilty judgment, what does two years punishment mean? They will be able to appeal against the judgment in higher courts.” Survivors, relatives and activists gathered in protest with signs saying “hang the guilty” and “traitors of the nation” and […]

(Beyond Pesticides, June 4, 2010) The U.S. Environmental Protection Agency (EPA) proposed new permit requirements for the discharge of pesticides into US waterways. EPA announced the public availability of a draft National Pollutant Discharge Elimination System (NPDES) General Permit for certain pesticide use patterns, also known as the Pesticides General Permit (PGP). The agency is accepting public comments until July 19, 2010. This action stems from a 2009 court decision in the case of the National Cotton Council et al. v. EPA, in which the 6th circuit court of appeals ruled that pesticide discharges into water are pollutants and require permitting under the Clean Water Act (CWA). This ruling overturned the Bush administration policy that exempted pesticides from regulation under the CWA, and instead applied the less stringent standards of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). CWA uses a kind of health-based standard known as maximum contamination levels to protect waterways and requires permits when chemicals are directly deposited into rivers, lakes and streams, while FIFRA uses a highly subjective risk assessment that does not consider safer alternatives. EPA will issue permits in territories, Indian Country Lands, 6 states and the District of Columbia where the Agency is […]

(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 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 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 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 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 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 […]
