(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 16, 2008) According to a new study, published in the December 2008 issue of Environmental Health Perspectives by researchers at Columbia University’s Mailman School of Public Health, pregnant women continue to be exposed to pesticides in the home. In fact, 75% of the sampled homes of pregnant women in inner-city New York are contaminated with piperonyl butoxide (PBO), a pesticide synergist linked to cancer and other health problems. Following the Environmental Protection Agency’s phase-out agreements with the manufacturers of organophosphate insecticides chlorpyrifos and diazinon in 2000 and 2001, the Columbia University researchers sought to determine the impact of the new regulations on pest infestation levels, pesticide use, and pesticides measured in indoor air samples. They enrolled 511 pregnant women from inner-city New York between 2000 and 2006. Permethrin, a pyrethroid insecticide; PBO, a pyrethroid synergist; chlorpyrifos; and diazinon were measured in 48-hr prenatal personal air samples. Data on pest infestation and pesticide use were collected via questionnaire. 88% of women report using pesticides during pregnancy and 55% report using higher-exposure pesticide applications (spray cans, pest bombs and/or professional pesticide applicators). Self-reported pest sightings and use of higher-exposure applications increased significantly after the regulations were implemented. PBO, cis-, […]

(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 10, 2008) Most families don’t realize that they might be bringing more than holiday cheer into their homes this Christmas season. Families celebrating this holiday season with the time-honored tradition of a Christmas tree can choose to go green and avoid the toxic chemicals that are typically used to grow it. Beyond Pesticides recently launched a Christmas Trees and Pesticides web page to help inform consumers this holiday season. Of the pesticides that the Environmental Protection Agency (EPA) has registered for use on Christmas trees, most are linked to one or more adverse effects, including cancer, hormonal disruption, neurotoxicity, organ damage, reproductive/birth defects, asthma, environmental effects and more. Their use results in exposure to workers, wildlife, and waterways. Beyond Pesticides has compiled a list of 25 pesticides commonly used or recommended for use by state agricultural extension services, including: 2,4-D, bifenthrin, chlorpyrifos, diazinon, esfenvalerate, glyphosate, simazine and more. Oregon, North Carolina, Michigan, Pennsylvania, Wisconsin, Washington, New York, and Virginia are the nation’s top Christmas tree producing states, and together account for more than half of the trees grown in the U.S. The Cooperative Extension Service of North Carolina reports that glyphosate -a pesticide linked to increased risk […]

(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, December 5, 2009) On November 10, 2008, the Austrian government released a report of long term research showing genetically engineered (GE) corn fed to mice significantly reduced their fertility over three to four breeding cycles within one generation. Similar effects were found in mice fed GE corn and bred over four generations. The study, “Biological effects of transgenic maize NK603xMON810 fed in long term reproduction studies in mice,” was sponsored by the Austrian Ministry of Health, Families, and Youth, and led by Dr. Jürgen Zentek, Professor of Veterinary Medicine at the University of Vienna. Three series of experiments were done. The first was a multigeneration feeding trial in which the mice were fed and bred for four successive generations, beginning with the parents that were fed the diets from birth. The second was a multi-cycle breeding trial lasting 20 weeks in which breeding pairs of mice were fed beginning one week prior to co-habitation until the end of experiment, and allowed to go through four breeding cycles in the same generation. The third was a life-term trial involving feeding the mice without breeding from conception (via the pregnant mothers) to their eventual death. The researchers report that it […]

(Beyond Pesticides, December 2, 2008) Tributyltin (also known as TBT), a ubiquitous pollutant that has a potent effect on gene activity, could be promoting obesity, according to an article in the December issue of BioScience, the journal of the American Institute of Biological Sciences. The chemical is used in antifouling paints for boats, as a wood and textile preservative, and as a pesticide on high-value food crops, among many other applications. Tributyltin affects sensitive receptors in the cells of animals, from water fleas to humans, at very low concentrations–a thousand times lower than pollutants that are known to interfere with sexual development of wildlife species. Tributyltin and its relatives are highly toxic to mollusks, causing female snails to develop male sexual characteristics, and it bioaccumulates in fish and shellfish. Recent research has found it in deep-sea squids and octopods, and it has been banned for maritime use by an international treaty. The harmful effects of the chemical on the liver and the nervous and immune systems in mammals are well known, but its powerful effects on the cellular components known as retinoid X receptors (RXRs) in a range of species are a recent discovery. When activated, RXRs can migrate into […]

(Beyond Pesticides, December 1, 2008) A new study by researchers at the University of California Los Angeles finds chronic exposure to commonly used dithiocarbamate fungicides, such as ziram, contribute to the development of Parkinson’s disease. According to the study, Ziram Causes Dopaminergic Cell Damage by Inhibiting E1 Ligase of the Proteasome, published in the Journal of Biological Chemistry, researchers screened several pesticides for their ability to interfere with the ubiquitin-proteasome system (UPS). Impaired UPS activity is reported in Parkinson’s disease patients’ brains. The researchers then focused on dithiocarbamate fungicides because they were found to be one of the most potent UPS inhibitors and are commonly used. The researchers discovered the mechanisms by which the UPS is impaired, showing that ziram and structurally related dithiocarbamates inhibit E1 ligase (a protein activating enzyme). Ziram is also found to increase alpha-synuclein (a protein expressed in the central nervous system) levels and selectively damages dopaminergic neurons in vitro. The study also cites unpublished data from a population-based study in central California that is determining pesticide exposure using state application registry, finding that individuals living within 500 meters of where ziram is applied are at three times the increased risk of developing Parkinson’s compared to […]

(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 18, 2008) At least one in four of the 697,000 U.S. veterans of the 1991 Gulf War suffer from Gulf War illness, a condition caused by exposure to toxic chemicals, including pesticides and a drug administered to protect troops against nerve gas, and no effective treatments have yet been found, a federal panel of scientific experts and veterans concludes in a landmark report released November 17, 2008. The Congressionally-mandated Research Advisory Committee on Gulf War Veterans’ Illnesses presented the report to Secretary of Veterans Affairs James Peake at Veterans Administration (VA) headquarters in Washington, DC. Scientific staff support to the Committee is provided by the Boston University School of Public Health (BUSPH). “The extensive body of scientific research now available consistently indicates that Gulf War illness is real, that it is the result of neurotoxic exposures during Gulf War deployment, and that few veterans have recovered or substantially improved with time,” the report says. The 450-page report brings together for the first time the full range of scientific research and government investigations on Gulf War illness and officially resolves many questions about the condition. The report found that Gulf War illness fundamentally differs from stress-related syndromes described […]

(Beyond Pesticides, November 17, 2008) A toxic soup of the most commonly used pesticides frequently detected in nature can adversely affect the environment and decimate amphibian populations even if the concentration of the individual chemicals are within limits considered safe, according to University of Pittsburgh research published in the online edition of Oecologia. The results of this study build on a nine-year effort to understand potential links between the global decline in amphibians, routine pesticide use, and the possible threat to humans in the future. Amphibians are considered an environmental indicator species because of their unique sensitivity to pollutants. Their demise from pesticide exposure could foreshadow the fate of less sensitive animals, according to study author Dr. Rick Relyea, Ph.D., an associate professor of biological sciences in the University of Pittsburgh’s School of Arts and Sciences. Leopard frogs, in particular, are vulnerable to contamination; once plentiful across North America, their population has declined in recent years as pollution and deforestation has increased. Dr. Relyea exposed gray tree frog and leopard frog tadpoles to small amounts of the ten pesticides that are widely used throughout the world. Dr. Relyea selected five insecticides: carbaryl, chlorpyrifos, diazinon, endosulfan, and malathion; and five herbicides: […]

(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 11, 2008) Researchers at the Duke University School of Medicine have linked organophosphate pesticides to the epidemics of obesity and type 2 diabetes. The researchers specifically link neonatal low-dose parathion exposure in rats to disruption of glucose and fat homeostasis. The study, “Exposure of Neonatal Rats to Parathion Elicits Sex-Selective Reprogramming of Metabolism and Alters the Response to a High-Fat Diet in Adulthood,” was published in the November 2008 issue of Environmental Health Perspectives. It follows research by the National Institutes of Health (NIH) that links pesticide exposure to type 2 diabetes using epidemiological data from the Agricultural Health Study. Although most studies of organophosphates focus on their neurotoxicity, there is increasing evidence that these agents may also have a lasting impact on metabolic function. According to authors, obesity and consequent type II diabetes are rising at epidemic rates in the U.S. and many other countries around the world. Two of three U.S. adults are now classified as overweight. There are epidemiologic links between pesticide exposure and diabetes, and the same subpopulations that have the highest rates of obesity””inner-city, low-socioeconomic-status, agricultural populations””are also those that have greater exposure to organophosphates and other pesticides. The researchers chose parathion […]

(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, November 7, 2008) The European Parliament’s environment committee has passed new measures aimed at reducing use and toxicity of pesticides used on crops throughout the European Union (EU). If approved by Parliament at the end of the year, the EU will be on its way to reducing pesticide use by 85 percent by 2013. The measure faces significant backlash from the chemical industry and conventional farmers, but committee members (MEPs) remain firm that the restrictions are both important and possible to do. An official report published last month found record levels of pesticide residues on EU food, giving momentum to pesticide restrictions. One adopted regulation will cause a list of approved “active substances” to be drawn up, according to which pesticides will be registered at a national level. It also allows EU states to be stricter than the allowable list. One amendment says, “Member states may establish any pesticide-free zones they deem necessary in order to safeguard drinking water resources. Such pesticide-free zones may cover the entire Member State.” The second approved measure, passed on to Parliament by EU agricultural ministers in June, bans “certain highly toxic chemicals,” those being endocrine disrupting, genotoxic, carcinogenic or toxic to reproduction. […]

(Beyond Pesticides, November 6, 2008) Agricultural biotech seed and chemical giant Monsanto will acquire Aly Participacoes Ltda., a Brazilian company involved in breeding sugar cane, and has already begun work to develop genetically engineered (GE) Roundup Ready (herbicide resistant) sugarcane. The deal for $290 million comes at the same time grain giant Archer Daniels Midland (ADM) is set to invest $375 million in a joint venture with a Brazilian firm to produce sugarcane-based ethanol. Amidst numerous other concerns with the widespread adoption of GE crops and the proliferation of crops grown for biofuels around the world is the threat of increased pesticide use. Roundup Ready crops, which are genetically engineered to be resistant to Monsanto’s best selling herbicide Roundup (active ingredient glyphosate https://www.beyondpesticides.org/gateway/pesticide/glyphosate.htm) have been a boon to Monsanto’s profits, but not without environmental costs. Currently grown Roundup Ready crops include soy, corn, canola, cotton, and sugar beets. The crops’ resistance to glyphosate enables the use of the herbicide during the growing season without harming the crop itself. Glyphosate is now the number one herbicide in the United States. This has serious implications for public health and the environment, as glyphosate has been linked to cancer, reproductive effects, kidney and […]

(Beyond Pesticides, November 5, 2008) The Environmental Protection Agency (EPA) acknowledged in a recent Federal Register Notice that antimicrobial pesticides in wide use are not adequately tested for their impacts on human health and the environment. Controversy surrounding the impacts of many antimicrobials in the environment has arisen in recent times to due to the prevalence of these chemicals in surface and drinking waters. Antimicrobials are defined by the EPA as “pesticides that are intended to (1) disinfect, sanitize, reduce, or mitigate growth or development of microbiological organisms, or (2) protect inanimate objects from contamination, fouling, or deterioration caused by bacteria, viruses, fungi, protozoa, algae, or slime.” For this proposal, the EPA is using the term antimicrobials to collectively refer to antimicrobial pesticides, antifoulant coatings and paints, and wood preservatives. The use of the controversial antimicrobial, triclosan, in inanimate objects, such as plastic and textiles, would be covered by these regulations, while those personal care products with the very same ingredient would not, since they fall under Food and Drug Administration authority. In the Federal Register last month, EPA, trying to play catch-up with the science while products continue in larger and larger numbers to incorporate the controversial antimicrobials, issues […]

(Beyond Pesticides, November 3, 2008) A new study, Pyrethroid pesticides and their metabolites in vacuum cleaner dust collected from homes and day-care centers (doi:10.1016/j.envres.2008.07.022), by the U.S. Environmental Protection Agency’s (EPA) National Exposure Research Laboratory finds concentrations of 13 synthetic pyrethroids and their degradates in indoor dust collected from homes and childcare centers in North Carolina and Ohio. The study results show the extent to which hazardous pesticides are present in indoor environments and threaten the public’s health, especially the health of children. With 85 vacuum cleaner bags analyzed, permethrin was present in all 85 dust samples, at least one pyrethroid pesticide was found in 69 samples and phenothrin was found in 36 samples. According to the study findings published in the November issue of the journal Environmental Research, the median concentration of permethrin in the samples is 1454ng/g of dust. Excluding permethrin, pyrethroid conectrations are less than or equal to 100ng/g of dust. The majority of the metabolites are present in more than half of the dust samples. This is not the first time researchers have found pesticides in dust in homes. A study published in the International Journal of Hygiene and Environmental Health (208: 193-199) also found that […]

(Beyond Pesticides, October 30, 2008) In an effort to keep its popular yet toxic herbicide 2,4-D on the market, Dow AgroSciences has filed a notice with the Canadian government claiming that Quebec’s ban on cosmetic use of pesticides breaches legal protections under the North American Free Trade Act (NAFTA). The company is likely to pursue compensation from Canada’s federal government under Chapter 11 of NAFTA, which restricts a country from taking measures “tantamount to nationalization or expropriation” of an investment. Despite the threat of legal action, Ontario, which instituted restrictions similar to Quebec’s earlier this year, says it will go ahead with its ban. Public health and environmental advocates have raised concerns that companies are using NAFTA to prevent governments from taking actions to regulate pollution and health threats, and they also warn that the companies’ actions may have a serious public backlash. Chapter 11 of NAFTA is just one of the legal avenues pesticide manufacturers have to make stricter pesticide regulation cumbersome, expensive, and in some cases impossible. For example, 41 states in the U.S. have preemption laws that prohibit municipal authorities from creating pesticide regulation that is more restrictive than the state’s. In a statement that could equally […]

(Beyond Pesticides, October 29, 2008) Two of the largest pineapple growers, Dole and Del Monte, have agreed to stop using endosulfan on pineapples grown on their plantations in the Philippines, beginning next year. The companies have opted not to renew their licenses for the use of this highly toxic chemical but instead will consider a list of alternative pesticides. The Philippines is one of the few countries that still allow the use of endosulfan, though on a restricted basis. Endosulfan is used on pineapple plantations to kill pineapple mites that cause pink disease, a discoloration of canned fruits. This measure to stop the use of endosulfan has been attributed to the recent sinking of the ship MV Princess of the Stars, whose cargo hull contained ten tons of endosulfan. The ship capsized and partially sank on June 21 in a typhoon, killing nearly 800 people onboard. In the wake of that tragedy, leaders in the Philippine government called for an end to endosulfan exemptions granted to foreign companies. Frustrations were raised over the potential for toxic contamination which threatens the health of the Philippine people. 400 packs of endosulfan, each pack weighing 25 kilograms, or a total of 10 metric […]

(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 24, 2008) A report to be released October 27 by public health groups and leading Maryland health and elder care facilities documents new practices and policies to eliminate toxic pesticide use. The changes reflect a heightened awareness of the need to protect particularly vulnerable populations from serious health risks associated with toxic chemical exposure. A growing body of scientific research links pesticides to Parkinson’s disease, asthma, cancer and other illnesses. “The Maryland health care institutions in the report are to be commended for showing national leadership in adopting non-toxic pest management techniques that protect the health of patients, visitors and staff,” said Jay Feldman, the report’s co-author and executive director of Beyond Pesticides. The report, “Taking Toxics out of Maryland’s Health Care Sector: Transition to Green Pest Management Practices to Protect Health and the Environment,” was co-written by the Maryland Pesticide Network, a statewide coalition advocating safe pest management practices, and Beyond Pesticides, a national environmental and public health group, under their joint “Integrated Pest Management (IPM) in Health Care Facilities Project,” and in collaboration with Maryland Hospitals for a Healthy Environment at the University of Maryland School of Nursing. IPM is an approach to pest management […]
