(Beyond Pesticides, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, February 18, 2009) The Environmental Protection Agency (EPA) is accepting through February 23, 2009 public comments on a petition to cancel all registrations for the herbicide 2,4-D and to revoke all of its tolerances. The petition was filed by the Natural Resources Defense Council (NRDC) in November and published by EPA on December 24, 2008. As the most commonly used “home and garden” chemical, millions of U.S. households especially vulnerable children and pets, are exposed to this toxic chemical. Beyond Pesticides fully supports the cancellation of this dangerous pesticide which has been associated with a host of adverse human impacts, such as non-Hodgkin’s lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. The highly toxic chemical can be replaced by cost-competitive and effective management practices widely used in organic agriculture and lawn care. As long as 2,4-D remains on the market, the public will continue to be exposed to, and suffer the effects of this chemical whose health impacts have long been ignored by EPA. Public health and environmental advocates believe it is time that EPA put science and the health of the public and the environment first and ban […]

(Beyond Pesticides, January 30, 2009) In a report released last week, the Government Accountability Office (GAO) added the Environmental Protection Agency (EPA) to its list of agencies in most need of reform. EPA appears in GAO’s High Risk Series: An Update, alongside the newly added U.S. Financial Regulatory System and the Food and Drug Administration (FDA). Reasons for EPA’s addition include a lack of transparency and information needed to limit potential health risks caused by chemicals under review, echoing testimony given to the Senate Committee on Environment and Public Works last spring. “EPA does not have sufficient chemical assessment information to determine whether it should establish controls to limit public exposure to many chemicals that may pose substantial health risks,” the report states. “Actions are needed to streamline and increase the transparency of the Integrated Risk Information System (IRIS) and to enhance EPA’s ability under the Toxic Substances Control Act to obtain health and safety information from the chemical industry.” New EPA administrator Lisa Jackson responded to the report with a prepared statement. “It is clear that we are not doing an adequate job of assessing and managing the risks of chemicals in consumer products, the workplace, and the environment,” […]

(Beyond Pesticides, January 13, 2009) In another stinging defeat for the Bush Environmental Protection Agency (EPA), on January 7, 2009, the 6th Circuit Court of Appeals issued a clear rebuke of the administration’s 2006 rule which exempted certain commercial pesticide applications from the oversight provided by Congress under the Clean Water Act. [The National Cotton Council et al. v. EPA (Nos. 06-4630; 07-3180/3181/3182/3183/3184/3185/3186/3187/3191/3236). See also Headwaters, Inc. v. Talent Irrigation Dist., 243 F.3d 526, 532-33 (9th Cir. 2001).] The Court held that pesticide residuals and biological pesticides constitute pollutants under federal law and therefore must be regulated under the Clean Water Act (CWA) in order to minimize the impact to human health and the environment. According to Beyond Pesticides, the EPA rule had allowed the weaker and more generalized standards under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to trump the more stringent CWA standards. 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 with no attention to the safest alternative. Read Beyond Pesticides’ press release on EPA’s 2006 decision. Several manufacturers […]

(Beyond Pesticides, January 8, 2009) Washington State’s model health protection programs are expected to be hit hard by Governor Chris Gregoire’s proposed budget cuts despite the minimal costs of running these essential programs, according to local activists in the state. The governor’s proposed budget will decimate the Washington Department of Health (DOH) Pesticide Program, including the Pesticide Incident Reporting and Tracking (PIRT) program, and the state’s Poison Control Center. Farm workers, children and the uninsured will likely be most affected. The proposed budget imposes almost no cuts to entities supported by the agrochemical industry. According to Carol Dansereau, an attorney with the Farm Worker Pesticide Project, and Liesl Zappler, PIRT Panel’s public member, the proposed cuts will eliminate half of the DOH’s Pesticide Program staff. DOH staff-time goes to pesticide incident interviews, toxicology research, sampling, gathering medical and spray records, analyzing and reviewing data, transmitting data, and writing reports including the PIRT report. DOH also works with growers and applicators to prevent accidental poisonings. The proposed DOH budget cuts also explicitly eliminate the PIRT Panel and its reporting requirements even though the PIRT Panel activities costs’ are minimal. Last year, DOH contributed $13,000 to PIRT; and with cuts instituted this […]

(Beyond Pesticides, January 5, 2009) According to a new study published December 2008 in the online edition of Environmental Health Perspectives, hexavalent chromium (or chromium VI) found in the wood preservatives chromated copper arsenate (CCA) and acid copper chromate (ACC), is a human carcinogen following chronic oral exposure. Previous studies have shown that hexavalent chromium compounds can increase the risk of lung cancer via inhalation exposure. Chromium VI is the notorious chemical that caused cancer in the residents of Hinkley, CA and brought to light by the work of Erin Brockovich. The National Toxicology Program (NTP) conducted 2-year drinking water studies of chromium VI (as sodium dichromate dihydrate) in male and female F344/N rats and B6C3F1 mice. Exposure resulted in increased incidences of rare neoplasms of the squamous epithelium that lines the oral cavity (oral mucosa and tongue) in male and female rats, and of the epithelium lining the small intestine in male and female mice. The authors determined that chromium Vi is carcinogenic following administration in drinking water to male and female rats and mice. The International Agency for Research on Cancer (IARC), the U.S. Department of Health and Human Services, and the Environmental Protection Agency (EPA) each have […]

(Beyond Pesticides, December 19, 2008) In resopnse to an Environmental Protection Agency (EPA) published final Reregistration Eligibility Decision (RED) document for triclosan (October 29, 2008), groups are citing a serious lack of health and environmental protection and the agency’s failure to meet its statutory duty. Formal comments will be submitted to the agency during a comment period that ends at the end of December 2008. Groups have been invited to sign a joint statement. Triclosan is a synthetic, broad-spectrum antimicrobial agent that in recent years has exploded onto the consumer market in a wide variety of antibacterial soaps, deodorants, toothpastes, cosmetics, fabrics, plastics, and other products. Studies link triclosan to a range of health and environmental effects, from skin irritation, allergy susceptibility, bacterial and compounded antibiotic resistant, and dioxin contamination to destruction of fragile aquatic ecosystems. Many of Beyond Pesticides comments that were submitted on July 7, 2008 were considered and amendments were made to the risk assessment. However, despite many lingering issues related to triclosan continued threat to human and environmental health, the agency concluded that triclosan was eligible for reregistration. This means that the continued and expanding use of this chlorinated, bioaccumulative pesticide, with the ability to produce […]

(Beyond Pesticides, December 18, 2008) The New Zealand’s Environmental Risk Management Authority (ERMA) has announced it will ban the controversial organochlorine pesticide endosulfan, effective January 16, 2009. Endosulfan, already banned in numerous countries including all the European Union countries, is an insecticide used on a wide range of fruits and vegetables and also on athletic fields in New Zealand. Illegal residues have been found in beef destined for South Korea, resulting in enormous costs for New Zealand exporters. Use of endosulfan for agriculture continues in the U.S., despite causing severe health and environmental problems. A coalition of groups, including the Pesticide Action Network Aotearoa New Zealand (PAN ANZ), Soil and Health Association and Safe Food Campaign, have long campaigned for the banning of endosulfan. Earlier this year, the three organizations carried out a number of residue tests on produce to draw attention to the extent of endosulfan residues, especially in tomatoes. “We are delighted that ERMA has overturned its earlier ”˜proposed’ decision to keep using this pesticide,” stated Meriel Watts, Ph.D., co-coordinator of PAN ANZ. “It would have been deeply embarrassing for New Zealand to continue its use when the pesticide has entered the process for a global ban under […]

(Beyond Pesticides, December 12, 2008) A new study has found pesticides in surface waters around the United States. The U.S. Geological Survey (USGS) analyzed water from nine selected rivers, which are used as a source for public water systems and found that low levels of certain xynthetic chemicals remain in public water supplies after being treated in selected community water facilities. “Most of the man-made chemicals assessed in the USGS study are unregulated in drinking water and not required to be monitored or removed,” says Tom Jacobus, General Manager of the Washington Aqueduct. “These findings are not surprising and they will be important in helping regulators and assisting water utility managers arrive at decisions about future water treatment processes.” Scientists tested water samples for about 260 commonly used chemicals, including pesticides, solvents, gasoline hydrocarbons, personal care and household-use products, disinfection by-products, and manufacturing additives. This study did not look at pharmaceuticals or hormones. Low levels of about 130 of the synthetic chemicals are detected in streams and rivers before treatment at the public water facilities (source water). Nearly two-thirds of these chemicals are also detected after treatment. Most of the chemicals found are at levels equivalent to one thimble of […]

(Beyond Pesticides, December 11, 2008) In a recent study, researchers find that triclosan, the antibacterial agent found in many consumer products including soaps, toothpaste, cosmetics, counter tops and toys, alters thyroid function in male rats. These effects are observed at concentrations that may be used in consumer products and highlight the growing threat consumers face from this hazardous and ubiquitous chemical. The study, entitled, “The effects of triclosan on puberty and thyroid hormones in male wistar rats,” was reviewed by the National Health and Environmental Effects Research Laboratory, the U.S. Environmental Protection Agency (EPA) and approved for publication in Toxicological Sciences. Researchers measured blood concentrations of testosterone and several other types of hormones and weighed a variety of organs that are essential for rat development and puberty, including the pituitary gland, the testes, the prostate gland and the liver of male rat pups fed an oral dose of triclosan for 31 days. The purpose of the experiment was to determine what effects triclosan would have on concentrations of thyroid hormones and the onset of puberty. Results show a dramatic decrease in the thyroid hormone -thyroxine in rats exposed to increasing concentrations of triclosan, as well as significant increases in liver […]

(Beyond Pesticides, December 8, 2008) A new study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds the pesticide poisoning incidence rate among U.S. agricultural workers is thirty-nine times higher than the incidence rate found in all other industries combined. The study, “Acute Pesticide Poisoning Among Agricultural Workers in the United Sates, 1998-2005,” published in the December issue of the American Journal of Industrial Medicine, is believed to be the first detailed multi-state assessment of acute pesticide poisonings among agricultural workers. From 1998 to 2005, a total of 3,271 cases of acute occupational pesticide-related illness/injury among agricultural workers were identified in ten states. According to EPA, the Worker Protection Standards are designed to reduce the risk of injury or illness to agricultural field workers resulting from exposure to pesticides. Although the WPS was expanded in 1995 and in 2005 EPA developed a new WPS How to Comply (HTC) Manual, the NIOSH findings indicate that agricultural workers continue to have an elevated risk for acute pesticide poisoning. Furthermore, female agricultural workers experienced nearly twice the risk of pesticide poisoning of male agricultural workers. The most common factors that contributed to pesticide exposure included off-target drift, early reentry into […]

(Beyond Pesticides, November 25, 2008) A new report on U.S. chemical security, which includes two pesticide and 30 bleach manufacturing plants on its list of 101 most dangerous chemical facilities, was released November 19, 2008 by the Washington-based think tank Center for American Progress (CAP). The report, Chemical Security 101: What You Don’t Have Can’t Leak, or Be Blown Up by Terrorists, calls on chemical plants to substitute for their most hazardous chemicals and processes to protect the lives and health of 80 million people living near the 101 worst facilities. The Department of Homeland Security (DHS) and numerous security experts have repeatedly warned that terrorists could use industrial chemicals as improvised weapons of mass destruction. However, according to CAP, current chemical security efforts are inadequate to protect workplaces and communities. “Indeed, temporary standards enacted two years ago (and set to expire in 2009) focus almost entirely on physical security measures, such as adding gates and guards,” say report authors Paul Orum and Reece Rushing. “These measures, however worthy, cannot assure protection against a concerted attack, insider sabotage, or catastrophic release. Nor do they protect communities along chemical delivery routes. More than 90 percent of the 101 most dangerous facilities […]

(Beyond Pesticides, November 24, 2008) Acknowledging the critical need for in-depth review of products utilizing nanotechnology pesticides, the Environmental Protection Agency (EPA) opened a 60-day public comment period in response to a petition filed by the International Center for Technology Assessment (ICTA) which demands the agency stop the sale of numerous consumer products with nano-silver. In the Federal Registry notice released Wednesday, EPA determined that ICTA’s petition “raises serious issues that potentially affect private and public sector stakeholders” and is instituting a 60-day period for public comment. EPA will review the petition and any comments received “before deciding how best to respond to the petition.” ICTA filed a legal petition in May 2008 challenging EPA’s failure to regulate nanomaterials in pesticides. The 100-page petition addresses the serious human health concerns raised by these unique substances, as well as their potential to be highly destructive to natural environments, and calls on the EPA to fully analyze the health and environmental impacts of nanotechnology, regulate nano products as new pesticides, and require labeling of all products. “It’s unfortunate that it has taken seven months, but the agency has taken the first step towards potential regulation of these products and protection of the […]

(Beyond Pesticides, November 19, 2008) In what is described as a great victory for environmental campaigner Georgina Downs, a British high court ruled last week that there was “solid evidence” that rural residents had suffered harm from crop spraying with toxic chemicals. The landmark ruling ordered the Government to reconsider how to protect the health of countryside communities. This victory comes after a long-running legal battle over the use of pesticides in rural communities. Ms. Downs, who lives on the edge of farmland, launched her campaign in 2001 and documented that she was first exposed to pesticide spraying in the early 1980s at the age of 11 and has since suffered from ill health, flu-like symptoms, sore throat, blistering and other problems. She created a DVD portraying collected evidence from other rural residents reporting health problems including cancer, Parkinson’s disease and asthma believed to be linked to crop spraying. Ms. Downs said the government had failed to address the concerns of people living in the countryside. She added that these people “are repeatedly exposed to mixtures of pesticides and other chemicals throughout every year, and in many cases, like mine, for decades.” She also noted that people were not given […]

(Beyond Pesticides, November 13, 2008) The Canadian Cancer Society is holding a conference to look at the possibility of advocating for stricter farm pesticide laws. The Cancer Society has been a vocal advocate for the cosmetic pesticide restrictions that have passed in the provinces of Ontario and Quebec as well as many municipalities, but it has not yet taken a stance on the much larger use of agricultural pesticides. Health Canada, the Canadian entity responsible for pesticide regulation insists, as the U.S. Environmental Protection Agency does in the U.S., that registered pesticides do not pose a substantive health risk when used as directed, but mounting scientific evidence shows otherwise. Many of the same chemicals that Canadian provinces have banned for cosmetic use, such as the herbicide 2,4-D, are used in much higher volumes in agriculture than on lawns. Since the Cancer Society is a strong voice in favor of the cosmetic pesticide bans because of the dangers of pesticides, it is logical that they would also be concerned about agricultural pesticide use. In other words, “It’s very hard to argue that the cosmetic use of pesticides poses a public-health risk, including cancer risk, and not examine what is going on […]

(Beyond Pesticides, November 10, 2008) Despite unanimous criticism of its preliminary risk assessment by the environmental community, the U.S. Environmental Protection Agency (EPA), in its completed the Reregistration Eligibility Decision (RED) for the controversial antibacterial triclosan, concludes that all uses, with the exception of the paint use, are eligible for reregistation. Triclosan, which is expected to reach a market value of $930 million by 2009, has exploded on to the marketplace in recent years, growing 5 percent annually, in products from soaps, cosmetic and personal care products, toothbrushes and toothpaste, to plastic toys and textiles. EPA believes that levels of concern for triclosan have not been exceeded even though this pervasive chemical is shown to threaten human health and the environment. The agency has opened a public comment period on the RED which closes on December 29. 2008. Triclosan accumulates in fatty tissue and has been found in breast milk and urine. It has also been linked to hormone disruption and has contaminated most of the nation’s waterways. Its degradates are also known to be persistent, to bioaccumulate and interfere with the hormone system. Triclosan has also been implicated in antibacterial and antibiotic resistance, which has severe consequences in medical […]

(Beyond Pesticides, October 27, 2008) Six pesticides that threaten water quality and public health continue to be detected in groundwater samples, according to a new U.S. Geological Survey (USGS) study. Published in the Journal of Environmental Quality, the study evaluates groundwater contaminants from samples taken from over 300 wells across the U.S. Over the years, frequent research has detected pesticides in ground water around the country, including in aquifers used for drinking-water supply. Over the past few decades, the use of some pesticides has been restricted or banned, while new pesticides have been introduced. One goal of the study was to track the retention of various types of contaminants that would be found in the different pesticides used over the years. Original samples were taken from the wells from 1993-1995, and compared with samples taken from 2001-2003. Laboratory analysis was performed using methods that allowed detection of pesticide compounds at concentrations as small as 1,000 times below U.S. EPA drinking-water standards. Of the 80 compounds studied, six were detected in ground water from at least 10 wells during both of those sample periods. The six pesticide compounds detected are the triazine herbicides atrazine, simazine, and prometon; the acetanilide herbicide metolachlor; […]

(Beyond Pesticides, October 16, 2008) Some of America’s most pristine natural places are contaminated with toxic pesticides from illegal marijuana growing operations. Recent busts in the 1800 square mile Sequoia National Park revealed the use of imported and banned herbicides and insecticides in intensive growing sites. Rat poisons, or rodenticides, were also scattered around to kill small animals who might be tempted to nibble a plant. CNN reports that “millions of dollars are spent every year to find and uproot marijuana-growing operations on state and federal lands, but federal officials say no money is budgeted to clean up the environmental mess left behind after helicopters carry off the plants,” and this environmental mess is severe. The extent of marijuana growing on federal lands is unknown, but seven hundred grow sites were discovered in California in 2007-2008. Many of these operations are run by Mexican marijuana growing cartels and the chemicals used are illegally imported from Mexico. It is estimated that 1.5 lbs of fertilizers and pesticides is used for every 11.5 plants. For the five million plants uprooted in California in 2007, this amounts to over 650,000 lbs of fertilizers and pesticides. Agent Patrick Foy of the California Department of […]

(Beyond Pesticides, October 8, 2008) In May, the U.S. Department of Agriculture (USDA) abruptly halted its program that tracks pesticide usage in fruits, vegetables and field crops, only to have the U.S. Senate in July put the program back in the 2009 Senate budget bill. USDA cited the $8 million program expense as the reaon for the reports’ demise, however the move left scientists, public advocates and even industry groups surprised and concerned about carrying out their work without this information. The Agricultural Chemical Usage Reports, launched in 1990 and administered by the National Agricultural Statistics Service (NASS), issues pesticide usage data on crops, having been initiated in response to public concerns over the contamination of apples by the pesticide Alar.The information was also widely used by universities and food industry researchers to help farmers monitor and reduce the amount of pesticides they use. “We looked at the budget and said, “We can’t do everything we have been doing, and what are we going to get rid of?” said Mark Miller of NASS. However, a coalition of public interest groups which included Beyond Pesticides, NRDC, the Center for Food Safety, and the Union of Concerned Scientists argued that the Agricultural […]

(Beyond Pesticides, October 2, 2008) Beyond Pesticides and the other members of the National Organic Coalition (NOC) recently sent a letter outlining their concerns over the development of “sustainable” agriculture labeling standards, which are currently under discussion and entering the first phase of draft standards-setting, overseen by the Leonardo Academy under the American National Standards Institute (ANSI) guidelines. The coalition, along with many other organic farming advocates, say they cannot support a “sustainable” label because of what appears the inevitability that it will be “less than organic,” thus reversing progress organic agriculture has made in recent decades and “effectively driving markets to lower standards” that do not protect human health and the environment. After a long fought battle by organic advocates to maintain organic integrity under a national standard, organic agriculture has emerged not only as the most stringent standard for ensuring environmental and human health, it has also gained widespread consumer acceptance in the market place. The NOC letter states: “With a sustainable standard, whether intentional or unintentional, consumers will undoubtedly be led to believe that, in supporting the standard, they are contributing to improved practices. In fact, they are slowing the growth of standards [organic] that are critical […]

(Beyond Pesticides, October 1, 2008) Last week, a jury awarded $1 million in compensation to an organic farm in Santa Cruz, California, whose herbs were contaminated by pesticides. The jury found that organophosphate pesticides, used on vegetables on neighboring farms, drifted onto the organic farm, leaving the herbs in violation of organic standards. The organic farm, Jacobs Farm Del Cabo, filed a lawsuit against the pesticide application company Western Farm Service, Inc. in May 2007. The suit sought an order to stop Western Farm Service from spraying pesticides that contaminate crops at Wilder Ranch State Park, where Jacobs Farm leases 120 acres. Compensation for losses, in the sum of $1 million, which resulted from pesticide contamination, was also sought. The court ruled that pesticide applications by Western Farm Service resulted in trespass of the pesticides onto Jacobs Farm and were legally determined to be a nuisance depriving Jacobs Farm of the right to use and enjoy the land, caused by negligence on the part of Western Farm Services. The jury found that Jacobs Farm was damaged in the sum of $1 million and Judge Robert Atack ordered judgment in that amount against Western Farm Service. The organophosphates, chlorpyrifos, diazinon, and […]

(Beyond Pesticides, September 12, 2008) Widespread use of nanoscale silver will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, highlighting the need to identify research priorities concerning this emerging technology, according to a new report released this week by the Project on Emerging Nanotechnologies (PEN). However, existing information about the impact of silver on the environment offers a starting point for some assessments of nanosilver, the report argues. The issue of assessing the risks posed by nanoscale silver was highlighted after the Environmental Protection Agency’s (EPA) San Francisco office earlier this year imposed a landmark fine of over $200,000 on a California company selling computer keyboards and mouses coated with nanosilver. EPA issued the fine on the grounds that the products should have been registered under federal pesticide law because of the company’s germ-killing claims. In May, a coalition of groups also petitioned that EPA regulate nano products as pesticides. Similar fines have not been imposed since, but the action is increasing attention on the potential risks posed by nanoscale silver and oversight of nanotechnology as a whole. There currently are more than 200 manufacturer-identified nanosilver products on the market and contained in […]

(Beyond Pesticides, September 10, 2008) Following the report released by the National Marine Fisheries Service that identified 37 pesticides that pose risks to salmon and steelhead, Oregon state officials are moving ahead to set new safety benchmarks for seven pesticides of priority concern. A team from the Oregon Water Quality Pesticide Management Program identified seven priority hazardous pesticides: azinphos-methyl, chlorpyrifos, dacthal, diazinon, endosulfan, simazine and ethoprop, based on water-quality monitoring in five Oregon watersheds, including the Pudding River near Salem, as well as the Clackamas, Yamhill, Hood and Walla Walla watersheds. Three pesticides, azinphos-methyl, diazinon and chlorpyrifos have been detected at concentrations that exceed federal aquatic criteria in the Clackamas River Basin (See report here). Chlorpyrifos was detected at maximum levels more than twice the federal standard. The National Marine Fisheries Service report on the ecological damage associated with pesticide use reveals “overwhelming evidence” to suggest that 37 pesticides, including these seven, increase the chance of extinction for protected salmon and steelhead. The state is now turning to its own team of experts to set stringent benchmarks based on existing research on these chemicals of concern. Generally the U.S. Environmental Protection Agency (EPA) is charged with developing water quality standards […]
