(Beyond Pesticides, September 23, 2010) A study by U.S. Department of Agriculture (USDA) scientists and cooperators provides new details about how fertilizing soils with biosolids also introduces triclosan, an antibacterial agent in soaps and other cleaning supplies, into the environment. Results show that triclosan in biosolids is only slowly degraded and persists at low levels in the environment for long periods of time. Biosolids are illegal for use in organic agriculture. For this study, entitled “Fate of triclosan in agricultural soils after biosolid applications” and published in Chemosphere, Agricultural Research Service (ARS), chemist Clifford Rice, of the ARS Environmental Management and Byproduct Utilization Laboratory in Beltsville, Md., and his partners determined that triclosan levels in Class B biosolids from a Mid-Atlantic wastewater treatment plant averaged around 15.5 milligrams per kilogram. They collected surface soil samples from 26 farms in northern Virginia, mostly from pastures. Some fields had never been amended with biosolids and others had been amended with one to four applications of biosolids within the previous 9 months to 13 years. Most of the biosolid amendments came from the wastewater treatment plant in the study. Generally, conventional chemical-intensive farmers add “Class B” biosolids, also known as treated wastewater solids, […]

(Beyond Pesticides, September 22, 2010) Consumer food buying decisions have a direct effect on the health of the environment and those who grow and harvest food. Beyond Pesticides released its expanded Eating with a Conscience guide —now updated to include the 43 of the most commonly eaten fruits and vegetables, 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.” Eating with a Conscience 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 organic-certified food with the USDA organic seal as “the only system of food labeling that is subject to independent public review and oversight —ensuring consumers that toxic chemicals used to kill insects and unwanted plants (or weeds) in chemical-intensive food production are replaced by management practices focused […]

(Beyond Pesticides, September 16, 2010) Last week, the U.S. Department of Agriculture (USDA) announced that it will make available $6.37 million in federal funds for organic certification cost-share reimbursements for the fiscal year 2010. Recipients must receive initial certification or continuation of certification from a USDA accredited certifying agent and may be reimbursed for up to 75 percent of their organic certification costs, not to exceed $750 per year. According to a press release from the USDA Agricultural Marketing Service (AMS), these funds will be available through two cost-share programs that AMS manages: the Agricultural Management Assistance Program (AMA) and the National Organic Certification Cost-Share Program. Each program provides cost-share rebates to eligible organic producers and/or handlers receiving or renewing organic certification by a USDA accredited certifying agent through funds allocated to their respective state agriculture agencies. The states, in turn, review applications submitted by eligible producers and/or handlers and distribute funds accordingly. The 2008 Farm Bill, (the Food, Conservation and Energy Act of 2008 (7 U.S.C. 6523)), authorized $22 million in federal funds towards the National Organic Cost-Share Program to be distributed for five years following the passage of the bill. Coupled with the authorization provided by the Federal […]

(Beyond Pesticides, September 14, 2010) A new study confirms that indoor uses of consumer products, including pesticides, are the primary sources of indoor exposure to endocrine disruptors —chemicals that disrupt hormones and cause adverse developmental, disease, and reproductive problems— and shows that indoor levels are higher than those outdoors. Researchers from Silent Spring Institute, Columbia University, and the University of California-Berkeley measured airborne concentrations of endocrine disruptors in two California communities: Bolinas, a rural, affluent coastal town, and Richmond, a working-class city ringed by oil refineries. The study is published online in the September 1, 2010 issue of Environmental Science & Technology. The researchers analyzed 104 chemicals in 50 homes, including both chemicals that penetrate indoors from outdoor industrial and transportation sources and those from indoor use of consumer products and building materials. Similar levels of contamination were found inside homes in both communities, but outdoor levels were higher in Richmond. Among the chemicals found were pesticides, phthalates, parabens, PBDE flame retardants, and PCBs. A total of 38 pesticides are evaluated, including banned organochlorines (e.g., DDT, PCP), and current use products such as carbamates (e.g., propoxur), organophosphates (e.g., chlorpyrifos), and pyrethroids (cypermethrin). Thirteen pesticides were detected outdoors and sixteen pesticides […]

(Beyond Pesticides, September 8, 2010) The U.S. Environmental Protection Agency (EPA) has received a new Biological Opinion from the National Marine Fisheries Service (NMFS) with a finding that the application of products containing any of 12 organophosphate (OP) pesticides are likely to jeopardize federally listed threatened or endangered Pacific salmon and steelhead and their designated critical habitat. The 12 OPs addressed in this Biological Opinion, issued under the Endangered Species Act, are azinphos-methyl, bensulide, dimethoate, disulfoton, ethoprop, fenamiphos, methamidophos, methidathion, methyl parathion, naled, phorate, and phosmet. This opinion concludes that EPA’s registration of pesticides containing bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet are each likely to jeopardize the continued existence of one or more of the 28 endangered and threatened Pacific salmonids and are each likely to destroy or adversely modify designated critical habitat for one or more of the 28 threatened and endangered salmonids. NMFS reached this conclusion because predicted concentrations of these seven pesticides in salmonid habitats, particularly in floodplain habitats, are likely to cause adverse effects to at least one listed Pacific salmonids including significant reductions in growth or survival. EPA’s registration of bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet is also likely to result […]

(Beyond Pesticides, September 7, 2010) A new study, entitled Fruit and Soil Quality of Organic and Conventional Strawberry Agroecosystems, shows organic strawberry farming results in higher quality fruit and healthier soils. A growing number of consumers are choosing organic foods, believing them to be healthier for themselves and the environment. While most environmentalists agree that organic agriculture is generally more sustainable than conventional, nutritionists who believe organic foods to be more nutritious are currently in the minority. A detailed comparison of organic and conventional strawberry farms is the first study to examine both the soil health and the nutrient content of the fruit produced. Researchers found organically produced strawberries, while slightly smaller than conventional have higher antioxidant activity, longer shelf life, and fared better in taste tests. Soils on the organic farms are also found to be healthier with higher organic matter concentration, and greater microbial biodiversity. California strawberries make up 25% of total production worldwide and 87% of U.S. production. Conventional strawberry production is notoriously dangerous for farm worker health and the environment. After phasing out the ozone depleting fumigant methyl bromide, the California government is currently considering approval of methyl iodide a chemical so carcinogenic it is actually […]

(Beyond Pesticides, September 3, 2010) New research shows that silver nanomaterials, which are used in a number of consumer products as antimicrobial agents, can interrupt important cell signaling within male reproductive sperm cells, causing them to stop growing. In previous studies, scientists reported how smaller-sized silver nanoparticles — in the 10 – 25 nanometer range — decrease the growth of male stem cells when they are exposed at concentrations greater than 10 micrograms per milliliter (μg/ml). This new study, on the other hand, is the first to identify how the silver nanoparticles stop the sperm stem cells from growing, with the biggest effects from the smallest-sized nanoparticles tested. Like many other studies on the effects of nanotechnology, this study raises important questions about the potential hazards to human health due to the prolific use of silver nanoparticles in the market. Researchers tested the effects of different sizes, concentrations and coatings of silver nanoparticles on cell growth of mouse sperm cells. They compared silver nanoparticles coated with either hydrocarbons — at 15 nm, 25 nm and 80 nm diameters — or sugars — at 10 nm, 25 – 30 nm and 80 nm diameter. Exposure to the smaller sized particles led […]

(Beyond Pesticides, September 2, 2010) Beyond Pesticides, along with dozens of environmental and public health groups from across the country, sent a letter to members of the U.S. Senate Committee on Agriculture, Nutrition, and Forestry, urging the withdrawal of S. 3735, a bill that would strip the Clean Water Act of protections from pesticides. The bill, introduced by Senators Blanche Lincoln (D-AR) and Saxby Chambliss (R-GA), the Senate Agricultural Committee’s Chair and Ranking Member, seeks to 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. The groups say Congress should be supporting the Environmental Protection Agency (EPA) in fulfilling its task, rather than undermining laws that protect public health and the environment. Senators Lincoln and Chambliss argue 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. In their August 30th letter, the groups say, “CWA complements and does not duplicate the pesticide registration reviews conducted by EPA under FIFRA, which sets a general national standard that does not take into account conditions and […]

(Beyond Pesticides, August 31, 2010) As the Environmental Protection Agency (EPA) continues its review of the popular herbicide atrazine, a new study shows that male rats prenatally exposed to low doses of the gender-bending chemical are more likely to develop prostate inflammation and to go through puberty later than non-exposed animals. The research adds to a growing body of literature on atrazine, an herbicide used in agriculture, especially in corn and sugar cane production, and on golf courses and residential lawns. Atrazine and its byproducts are known to be relatively persistent in the environment, potentially finding their way into water supplies. It has been linked to a myriad of health problems in humans including disruption of hormone activity, birth defects, and cancer. The research, “Effects of prenatal exposure to a low dose atrazine metabolite mixture on pubertal timing and prostate development of male Long-Evans rats,” which is available online and will be featured on the cover of Reproductive Toxicology (Vol. 30, # 4), found that the incidence of prostate inflammation went from 48 percent in the control group to 81 percent in the male offspring who were exposed to a mixture of atrazine and its breakdown products prenatally. The severity […]

(Beyond Pesticides, August 26, 2010) While proponents of organic farming often speak of nature’s balance in ways that sound almost spiritual, a new study provides additional scientific evidence to back-up this world view. Ecologists from the University of Michigan and the University of Toledo have uncovered a web of intricate interactions that buffers the farm against extreme outbreaks of pests and diseases, making highly toxic magic bullets unnecessary. This latest study adds to the list of benefits provided by organic agricultural methods, which include: healthier food, a less toxic work environment for farmers and farmworkers, a source of carbon sequestration (which combats climate change), higher yields in drought conditions, and a healthier environment. The 10-year study, “Ecological Complexity and Pest Control in Organic Coffee Production: Uncovering an Autonomous Ecosystem Service,” is published in the July/August issue of the journal BioScience. According to the study, the major players in the system ””several ant species, a handful of coffee pests, and the predators, parasites and diseases that affect the pests”” not only interact directly, but some species also exert subtle, indirect effects on others, effects that might have gone unnoticed if the system had not been studied in detail. A key species […]

(Beyond Pesticides, August 25, 2010) Exposure to pesticides while in the womb may increase the odds that a child will have attention deficit hyperactivity disorder (ADHD), according to researchers at the University of California-Berkeley School of Public Health. Maternal metabolites of organophosphate pesticides have previously been associated with neurobehavioral deficits in children. The California researchers are studying the impact of environmental exposures on the health of women and children who live in the Salinas Valley, an agricultural region with heavy pesticide use. They tested the urine of pregnant women for pesticide residue, and then tested the behavior of their children at ages 3 ½ and 5. The 5-year-olds who had been exposed to organophosphate pesticides while in the womb have more problems with attention and behavior than did children who were not exposed. Results are published online in the study entitled, “Organophosphate Pesticide Exposure and Attention in Young Mexican-American Children,” in the journal, Environmental Health and Perspectives. Previous studies have shown that exposure to some organophosphate compounds cause hyperactivity and cognitive deficits in animals. One study published in Pediatrics earlier this year found that exposure to organophosphates in developing children might have effects on neural systems and could contribute to […]

(Beyond Pesticides, August 20, 2010) Behind closed doors this past Monday, the U.S. Environmental Protection Agency (EPA) and Bayer CropScience reached an agreement on a set of measures to gradually reduce and ultimately ban fully the use of the insecticde aldicarb in the U.S. This decision arrives on the heels of a revised risk assessment in which EPA found that babies and children under the age of five can ingest levels of the insecticide through food and drinking water at levels that exceed limits that the agency finds safe, and 25 years after 2,000 people fell ill after eating watermelons that were tainted with the pesticide. Though Beyond Pesticides applauds any decision to remove toxic chemicals from the environment, the problem with this cancellation, as with virtually all voluntary cancellations, is that the chemical can be legally used for years —eight years in this case — leaving open the opportunity for continued human and environmental exposure and harm. The decision was reached after EPA completed a revised risk assessment indicating that the pesticide does not meet the agency’s food safety standards. EPA scrutinized recent food consumption data from USDA to complete the risk assessment, which considered the percent of the […]

(Beyond Pesticides, August 17, 2010) A federal appeals court has revived the fraud and negligent misrepresentation claims by blueberry farmers in New Jersey, who say that a pesticide made by Novartis Crop Protection, Inc. reacted badly with fungicides and ruined their crops. Declaring that the lower court improperly dismissed the farmers’ state law claims as preempted by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the federal court concluded that farmers were not suing over the alleged flaws in the warning label-which is federally regulated -rather were complaining about misrepresentations in Novartis’ marketing brochure. The case, Indian Brand Farms Inc. v. Novartis Crop Protection Inc. was filed in the 3rd U.S. Circuit Court of Appeals in New Jersey. Blueberry farmers said Novartis should have warned them that a new version of its pesticide, including diazinon as the active ingredient, also included a surfactant that reacts badly with fungicides. The promotional brochure failed to mention this reaction and when farmers mixed the diazinon pesticide with the fungicides Captan and Captec, it caused phytotoxic damage, including blotches, depressions and spots, and in some cases killed their plants. It was not clear to the appeals court that the practice of combining pesticides with […]

(Beyond Pesticides, August 11, 2010) Independent tests of sewage sludge-derived compost from the Synagro CVC plant -distributed free to gardeners since 2007 by the San Francisco Public Utilities Commission (PUC) in their “organic biosolids compost” giveaway program — have found appreciable concentrations of contaminants with endocrine-disruptive properties. These contaminants include polybrominated diphenyl ether (PBDE) flame retardants, nonylphenol detergent breakdown products, and the antibacterial agent triclosan. The independent tests were conducted for the Food Rights Network by Robert C. Hale, PhD of the Virginia Institute of Marine Sciences. The antibacterial triclosan, an endocrine disruptor, was also found in the sewage sludge compost, at an average of 1,312 ng/g (or ppb). Last week, the Centers for Disease Control updated their National Report on Human Exposure to Environmental Chemicals and noted that triclosan levels in people increased by over 41% between just the years 2004 and 2006. Also last week, a scientific paper showed that triclosan from sewage sludge can be taken up by soybean plants and translocated into the beans themselves, then consumed by people and animals. PBDEs are persistent and bioaccumulate in the environment and elevated levels have been found in California citizens. The average total of the PBDE congeners tested […]

(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 6, 2010) Organic farmers and gardeners across a Washington state county suspect that herbicide-contaminated manure and compost obtained from non-organic farms and dairies are responsible for severe crop loss reported throughout the region, raising questions about the adequacy of the U.S. Environmental Protection Agency’s (EPA) pesticide registration process. Tests of soil and tissue samples of local dairy manure that is used in soil and compost mixtures revealed small amounts of aminopyralid, a potent and persistent herbicide approved for use by EPA in 2005. Aminopyralid is generally used for weed control in pastures and fields that grow silage crops for dairy cows. When cows eat the grass that has been treated with the chemical, it passes through them unchanged and remains in their manure in concentrations that can still be high enough to damage broadleaf crops if the manure is used to fertilize them. Aminopyralid is produced by Dow AgroSciences, a subsidiary of Dow Chemical Co., and often manufactured under the product name Milestone. Former coordinator of the Washington State University master gardeners’ program Jill Cotton has noticed the damage in her garden and said reports continue to filter in from other gardens around the county. One Whatcom […]

(Beyond Pesticides, August 5, 2010) A 400-year old large old grape vine considered to be the nation’s oldest in Manteo, North Carolina and known lovingly as “Mother Vine,” is slowly recovering from a powerful dose of herbicide sprayed by a utility company. The Virginia-based Dominion Power Company contracted Lewis Tree Service to spray power poles along the roads in the Manteo in May. The herbicide they used, Garlon3A, was accidentally sprayed on a tiny shoot from the vine that had grown a few feet up a pole on 84-year old Jack Wilson’s property. Unaware of the recent herbicide spraying by the utility power company, he noticed various brown, dead sections that began to appear in the plant in May. Not only did the vine suffer, but about 10 feet of a nearby hedge died, along with three limbs of a large pecan tree that had to be trimmed. The active ingredient in Garlon 3A, a Dow Chemical product, is triclopyr. It is a systemic herbicide which means that the poison spreads from the ends of the vine back toward the root. As a broadleaf weed killer, triclopyr is frequently used along rights-of-way and on industrial sites. In laboratory tests, triclopyr […]

(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—Küpfmüller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—Küpfmüller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and Küpfmüller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—Küpfmüller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

(Beyond Pesticides, Aug 2, 2010) A new report conducted by an Ann Arbor, Michigan based coalition of health and environmental groups estimates that children’s exposure to toxic chemicals, including pesticides, cost Michigan billions of dollars each year. The study examines the costs associated with four environmentally related childhood diseases: lead poisoning, asthma, pediatric cancer, and neurodevelopmental disorders. Treating these four disorders costs the state of Michigan an average of $5.85 billion annually. The study, “The Price of Pollution: Cost Estimates of Environment-Related Childhood Disease in Michigan” was released in time for the US House Energy and Commerce Committee hearings on the Toxic Chemicals Safety Act of 2010, an overhaul of the 1976 Toxic Substances Control Act (TSCA). Using conservative estimates researchers consider direct costs such as medical treatment, as well as less direct costs such as parent wage losses. The study also notes the substantial emotional costs to families dealing with these potentially life threatening or debilitating conditions which cannot be quantified. Lead poisoning is found to be the most costly of the diseases studied, costing on average $4.85 billion annually, followed by childhood asthma, pediatric cancer, and neurodevelopmental disorders. These four disorders alone cost the state of Michigan 1.5% […]

(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 […]
