Large-scale Livestock Operation Decertified Organic by USDA

(Beyond Pesticides, December 7, 2009) In an investigation and legal case that dragged on for almost four years, one of the largest organic cattle producers in the United States, Promiseland Livestock, LLC, is suspended from organic commerce, along with its owner and key employees, for four years. The penalty is part of an order issued by administrative law judge Peter Davenport in Washington, DC on November 25, 2009, a multimillion dollar operation with facilities in Missouri and Nebraska, including over 13,000 acres of crop land, and managing 22,000 head of beef and dairy cattle, had been accused of multiple improprieties in formal legal complaints, including not feeding organic grain to cattle, selling fraudulent organic feed and “laundering” conventional cattle as organic. “We are pleased that justice has been served in the Promiseland matter,” said Mark A. Kastel, Senior Farm Policy Analyst for the Wisconsin-based Cornucopia Institute. Scrutiny from Cornucopia, one of the industry’s most aggressive independent watchdogs, was part of the genesis for the comprehensive USDA investigation and subsequent legal proceedings. Promiseland became the focus of Cornucopia’s investigation into giant factory farms, milking thousands of cows that were allegedly operating illegally. Promiseland sold thousands of dairy cows to giant factory […]

EPA Considers Higher Uncertainty Factor in All Pesticide Risk Determinations

(Beyond Pesticides, November 24, 2009) The Environmental Protection Agency (EPA) is considering expanding to all pesticides the use of what is typically referred to as the Food Quality Protection Act (FQPA) safety factor (the allowable margin of error or the uncertainty factor in risk determinations), which is currently only applied to the agency’s pesticide evaluations for infants and children. Under the plan the increased uncertainty factor will be applied to other sensitive populations, including farmworkers. Beyond Pesticides learned of the plan through communications with the agency over the past several months. EPA officials told Beyond Pesticides that, under the Obama Administration leadership, the agency would like to apply an equal standard to all people living in the U.S. Beyond Pesticides called on the Obama Administration to protect farmworkers and their children in the Transforming Pesticide Policy document sent after the 2008 election to President Obama’s transition team and top agency officials. Applying an additional uncertainty factor in risk assessments affecting infants and children and a reassessment of all existing pesticide tolerances were touted as the centerpieces of FQPA, which passed and amended the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), the federal pesticide law, in 1996. The legislation gained momentum […]

EPA Issues Minimal Fines to Three Companies for Pesticide Registration Violations

(Beyond Pesticides, November 20, 2009) Three companies in Washington, Oregon and Idaho are the target of enforcement actions for their failure to follow federal pesticide laws, according to orders issued by the Environmental Protection Agency (EPA). The fines range from $1,280 to $28,080, and are characterized by safety advocates as a mere slap on the wrist for violations that the EPA says pose public safety hazards. J.R. Simplot Company of Boise, Idaho; Agricare of Amity, Ore.; and Northwest Agricultural Products of Pasco, Wash. violated the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) at their respective facilities, according to the EPA. Numerous other violations of FIFRA this past year have led to EPA fines or lawsuits, including several in the state of Washington last spring. In October, EPA fined Samsung for violating the federal pesticide law when it publicized that its keyboards, produced with nanosilver, were antimicrobial and inhibited germs and bacteria without registering its products. EPA also filed suit against VF Corporation for the sale and distribution of unregistered pesticides through its retail company, The North Face. “Companies that produce pesticides but fail to register their facilities or submit required reports are not only operating illegally, but also pose a […]

Ohio Asks EPA to Allow Unregistered Pesticide Use for Bedbugs

(Beyond Pesticides, November 13, 2009) The Ohio Department of Agriculture is asking the U.S. Environmental Protection Agency (EPA) to allow an unregistered use of the neurotoxic and cancer causing insecticide propoxur in homes to fight bedbugs in what state officials are describing as an ”˜emergency’ situation. The chemical, o-isopropoxyphenyl methylcarbamate, is in the carbamate family and classified as a probable human carcinogen (Group B2) by EPA, and listed as a known human carcinogen by the state of California. Though EPA allows emergency exemptions for unregistered pesticide uses in agriculture and for public health reasons under a controversial waiver program (Section 18, Federal Insecticide, Fungicide and Rodenticide Act, 40 CFR Part 166), it rarely issues such an exemption for an indoor pesticide use. Columbus, Cleveland, and Cincinnati are all experiencing a surge of bed bug infestations. According to Richard Pollack, a Harvard University public health entomologist, this is probably due to the fact that bedbugs are becoming resistant to many pesticide products that are used today. The use of broad spectrum insecticides, which kill common household insects such as cockroaches, ants and other insects including bed bugs, has resulted in insect resistance to these chemicals. Many of the chemicals used against […]

EPA Proposes New Pesticide Labeling to Control Spray Drift

(Beyond Pesticides, November 5, 2009) The U.S. Environmental Protection Agency (EPA) has rolled out proposed guidance for new pesticide labeling in an effort to reduce off-target spray and dust drift. According to EPA, the actions detailed in the draft Pesticide Registration (PR) Notice on Pesticide Drift Labeling, when implemented, are projected to help improve the clarity and consistency of pesticide labels and help prevent harm from spray drift. The agency is also requesting comment on a petition to evaluate children’s exposure to pesticide drift. Last month, a petition filed by Earthjustice and Farmworker Justice asked EPA to set safety standards protecting children who grow up near farms from the harmful effects of pesticide drift. The groups also asked the agency to adopt an immediate no-spray buffer zone around homes, schools, parks and daycare centers for the most dangerous and drift-prone pesticides. According to the agency, the new instructions are said to prohibit drift that could cause “adverse health or environmental effects,” by evaluating scientific information on risk and exposure based on individual product use patterns on a pesticide-by-pesticide basis. These assessments will help the agency determine whether no-spray buffer zones or other measures, such as restrictions on droplet or particle […]

Groups Ask Senate to Reject Nomination of Pesticide Lobbyist

(Beyond Pesticides, November 4, 2009) Environmental and farm groups are asking the Senate to reject the Obama Administration pick for chief agriculture trade representative because of positions that he has taken in support of genetically modified organisms as a spokesman for the agrichemical industry, his attack of the European Union (EU) moratorium on genetically engineered crops as lacking “sound science,” and his organization’s outright opposition to organic agriculture and First Lady Michelle Obama’s efforts to advance organic gardening. Groups are calling for the rejection of the nomination of Islam Siddiqui, PhD, vice president for science and regulatory affairs at CropLife America, to be the chief agricultural negotiator in the Office of the United States Trade Representative. Dr. Siddiqui’s confirmation is scheduled for today in the Senate Finance Committee. The National Organic Coalition (NOC) sent a letter to the U.S. Senate Committee on Finance intending “to bring to the committee’s attention serious concerns and questions” surrounding the nomination of Dr. Siddiqui, including positions that promoted hazardous and unnecessary chemical dependency, as well as his advocacy of genetically modified organisms. NOC states in its letter that, “We have no reason to believe that, at this time, [Dr. Siddiqui’s] history of positions makes […]

White House Orders EPA to Move on Endocrine Disrupting Pesticides without Data; EPA Seeks Approval of Guidelines

(Beyond Pesticides, October 21, 2009) The U.S. Environmental Protection Agency (EPA) is making available the battery of scientific assays and test guidelines for conducting the assays for each of 67 chemicals included for Tier 1 testing for endocrine disrupting effects during the next three months. This comes after the Office of Management and Budget (OMB) instructed EPA to use existing toxicity data rather than require companies to conduct new tests to determine whether chemicals can damage the human endocrine system. With the availability of the assays and test guidelines, EPA will move forward with issuing test orders to manufacturers to compel the generation of the needed data. However, acquisition of new, relevant data may be limited. This is because after EPA submitted the request for additional information for OMB approval, the Office issued a directive that approved EPA’s request to collect additional data for the 67 chemicals but warned the agency that it should “to the greatest extent possible” accept existing data to satisfy test requirements. The OMB directive, which observers say contains unusually strong language, is being hailed by industry groups that had been concerned about the prospects for expensive testing mandates. But many environmental groups and scientists say […]

New Jersey Town Adopts Policy to Significantly Reduce Pesticide Use

(Beyond Pesticides, October 19, 2009) The “green” movement continues to sprout throughout New Jersey, as Hamilton Township joins other municipalities in the state that have made their parks pesticide-free zones and have adopted an Integrated Pest Management (IPM) program for managing town property. Responding to the request of local members of the New Jersey Environmental Federation, Hamilton Township recently passed a resolution adopting the Federation’s model pesticide reduction policy. The policy establishes Pesticide Free Zones for 50 feet surrounding township playgrounds, picnic grounds, pavilions and rest areas, dog parks and ballfields, as well as 300 feet from any stream bank, pond, lake or natural wetland. It also requires the implementation of an IPM program for all township buildings and grounds. Hamilton Mayor John F. Bencivengo endorsed the policy, stating that it is a great way to educate the public about pesticide use, and ensure that the township continues on its path of “pesticide free zones” in its parks, municipal building and library. Schools in New Jersey are already required by law to follow IPM plans using non-toxic methods first and conventional pesticides only if the non-toxic methods are ineffective. “It is easy to manage a lawn without harmful chemical pesticides,” […]

EPA Announces New Scientific Evaluation of Atrazine

(Beyond Pesticides, October 8, 2009) The U.S. Environmental Protection Agency (EPA) announced that it will launch a comprehensive new evaluation of the pesticide atrazine to determine its effects on humans this fall. At the end of this process, the agency will decide whether to revise its current risk assessment of the pesticide and whether new restrictions are necessary to better protect public health. This announcement follows recent scrutiny and findings that the current EPA regulation of atrazine in water is inadequate. In August this year, the Natural Resources Defense Council (NRDC) published a report, Poisoning the Well which found that the commonly used herbicide atrazine can spike at extremely high levels which go undetected by regular monitoring. Concurrently, The New York Times published an investigative piece based on the NRDC findings and confirmed that the public is not informed when reports of these spikes of atrazine in drinking water occur. One of the most widely used agricultural pesticides in the U.S., atrazine can currently legally be applied before and after planting to control broadleaf and grassy weeds. Its increased use to manicure home lawns and gardens has become a serious environmental concern as runoff has had severe health and environmental […]

EPA Announces Greater Public Participation In Pesticide Registrations

(Beyond Pesticides, October 7, 2009) The U.S. Environmental Protection Agency (EPA) is establishing a new transparent process that will allow the public to review and comment on risk assessments and proposed registration decisions for pesticides. This expanded process will apply to all new pesticide active ingredients and first food uses, first outdoor uses, and first residential uses. It is not clear at this writing whether the agency will at the same time release the underlying test data on potential adverse health effects that companies submit for product registration. Starting October 1, 2009, the public will be able to review and comment on the risk assessments and proposed registration decisions for certain pesticide registration actions. Upon receiving a complete application for registration for a new pesticide active ingredient or a new use of an already registered active ingredient, EPA will publish a Federal Register Notice of Receipt, establish a case docket in regulations.gov, and open an initial 30-day public comment. Following the comment period, EPA will publish its decision and a response-to-comment document. Once the agency’s risk assessments and proposed decision for the registration application are added to the docket, EPA will open another 30-day public comment period. After the final […]

EPA Seeks to Disclose Hazardous Pesticide Inert Ingredients

(Beyond Pesticides, October 2, 2009) The Environmental Protection Agency (EPA) announced that it is moving forward with a plan to disclose the identities of all so-called “inert’ ingredients in pesticides, including those that are potentially hazardous. EPA believes this increased transparency will assist consumers and users of pesticides in making informed decisions and will better protect public health and the environment. Pesticide manufacturers typically disclose their inert ingredients only to EPA. On September 30, 2009, EPA responded to two petitions, one by led by the Northwest Coalition for Alternatives to Pesticides and joined by Beyond Pesticides and 20 other organizations, and a second by certain State Attorneys General, that identified over 350 inert pesticide ingredients as hazardous. The petitioners asked EPA to require these inert ingredients be identified on the labels of products that include them in their formulations. In its response to petitioners, the agency said, “EPA agrees with the petitioners that the public should have a means to learn the identities of hazardous inert ingredients in pesticide product formulations. The agency believes that increased transparency could lead to better informed decision making and better informed pesticide use.” It continues, “EPA will also be discussing ideas to increase disclosure […]

Under Legal Pressure, EPA Announces New Plan to Protect Salmon from Pesticides

(Beyond Pesticides, September, 15, 2009) On September 11, 2009, the Environmental Protection Agency (EPA) announced plans to place additional limitations on the use of three organophosphate pesticides ”” chlorpyrifos, diazinon and malathion ”” to protect endangered and threatened salmon and steelhead in California, Idaho, Oregon and Washington. The announcement comes in response to a series of lawsuits brought by Pacific Coast Federation of Fishermen’s Associations (PCFFA), the Northwest Coalition for Alternatives to Pesticides, and other salmon advocates, with legal representation from Earthjustice, aimed at removing toxic pesticides from salmon spawning streams throughout the northwest. In response to the litigation, the National Marine Fisheries Service (NMFS) in November of 2008 released a “biological opinion” that set forth a plan for protecting Pacific salmon and steelhead from three toxic organophosphate pesticides. That decision came after almost a decade of legal wrangling between salmon advocates led by Earthjustice and the federal government. The biological opinion prescribed measures necessary to keep these pesticides out of water and to protect salmon populations in Washington, Oregon, California, and Idaho. The announcement from EPA moves this work forward. Although the experts at NMFS recommended prohibiting aerial applications of the three pesticides within 1,000 feet of salmon waters […]

EPA Fines Tree Nursery for Pesticide Misuse, Worker Safety Violations

(Beyond Pesticides, September 4, 2009) The U.S. Environmental Protection Agency (EPA) fined a Minden, Nevada-based ornamental tree nursery for misusing pesticides contrary to labeling requirements and failing to comply with federal pesticide worker safety laws. Genoa Tree Nursery misused the pesticide Diazinon AG500 during applications in May and June 2008. The company failed to comply with label directions that require it to minimize the risk of exposure by notifying workers and handlers of recent pesticide applications on particular fields, and failed to provide workers with nearest emergency medical care facility information in case of exposure. The applicator also did not receive safety training during the previous five years as required by law. EPA fined Genoa Tree Nursery a mere $5,440 for these violations. “Notifying employees about potentially harmful pesticide exposure is not just a good idea, it’s the law,” said Katherine Taylor, EPA’s Communities and Ecosystems Division associate director for the Pacific Southwest region. “Employers of agricultural workers must ensure their employees are provided with information and protections that minimize the risk of potential exposure to pesticides””failure to do so is a serious violation.” The Nevada Department of Agriculture discovered the violations during a routine inspection in June 2008.

Canadian Medical Association Calls for Ban of Household Products Containing Triclosan

(Beyond Pesticides, August 27, 2009) At its annual convention, the Canadian Medical Association called on the federal government to ban the sale of household antibacterial products such as those containing triclosan. The motion was proposed by Ottawa family physician Kapil Khatter, M.D., who is also president of the Canadian Association of Physicians for the Environment. He says he can understand the appeal of antibacterial products, but in reality they do more harm than good. Strong scientific evidence suggests that pervasive use of triclosan poses imminent threats to human health and the environment, which is why Beyond Pesticides and Food and Water Watch submitted an amended petition a month ago to the U.S. Food and Drug Administration (FDA) seeking to ban the use of the controversial pesticide triclosan for non-medical applications. The petition establishes that FDA’s allowance of triclosan in the retail market violates the Federal Food, Drug and Cosmetics Act. The CMA resolution echoes concerns raised not only by Beyond Pesticides, but also by the American Medical Association (AMA) that date as far back as 2000, citing the lack of studies pertaining to the health and environmental effects of its widespread use. Because no data exists to support the need […]

EPA Warns Companies about Misleading Label Claims

(Beyond Pesticides, August 18, 2009) In a letter to Responsible Industry for a Sound Environment (RISE), the national trade association representing producers and suppliers of specialty pesticides and fertilizers, the U.S. Environmental Protection Agency (EPA) clarifies for pesticide companies federal pesticide label regulations and the agency’s position on use of false and misleading claims like “Professional Strength.” The letter, dated May 15, 2009 and posted on EPA’s website last week, addresses pesticide products that are sold and distributed and labeled “Professional” and “Professional Grade” among others, in product names and advertising. EPA finds that such statements are “inappropriate.” According to the letter, “Section 12 (a) (1) (E) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), states that it is unlawful to distribute or sell ”˜any pesticide which is”¦.misbranded.’ A pesticide is misbranded if ”˜its labeling bears any statement, design or graphic representation relative thereto or to its ingredients which is false or misleading in any particular.’ FIFRA § 2(q)(1)(A) [emphasis added]. The following describes why EPA finds use of “Professional Grade” in these products’ labeling and marketing to be a false and misleading claim and therefore unacceptable.” The letter continues, “”¦’Professional Grade’ implies a falsehood that pesticides are classified […]

Use of Herbicide Glyphosate Up for Review on Alaskan Railway

(Beyond Pesticides, August 13, 2009) The Alaska Department of Environmental Conservation is currently reviewing a request by the Alaska Railroad for permission to use the herbicide glyphosate along a 90 mile stretch of its track between Seward and Indian. The herbicide is set to be applied on Railroad operating property (rail yards, spurs, sidings, etc) and along the mainline and branch line right-of way for four feet out from both sides of the track in the summer of 2010. Despite the fact that previous requests have been met with opposition, the railroad states that its vegetation problem has gotten too out of hand for “so-called ”˜alternative methods.’” They also state that the Federal Railroad Administration, the railroad’s federal regulatory agency, will impose fines and operational restrictions such as reducing speeds or emergency closures of some sections of track if they aren’t cleared of the overgrown vegetation. Current methods of weed management utilized by the railroad are mechanized rail-based brushcutters, off-rail hydroaxing, wayside manual cutting. The extents to which these methods are used are unknown, however, and the railroad states that these are effective””but only within limited ranges.

American Bird Conservancy Petitions EPA to Ban Import of Food Containing Deadly Pesticide Residues

(Beyond Pesticides, August 6, 2009) American Bird Conservancy has petitioned the U.S. Environmental Protection Agency (EPA) to ban the import of crops containing any residues of 13 pesticides that are banned or restricted for use in the United States. These pesticides are highly toxic to birds, but are commonly used on crops throughout Latin America where many species of U.S. migratory birds spend the winter months. In addition to the environmental risks to birds, several of these chemicals also pose a risk to agricultural workers. “Allowing residues of these hazardous pesticides on imported food gives tacit U.S. approval to foreign countries to use chemicals that are known to be deadly to U.S. migratory birds,” said Dr. Michael Fry, American Bird Conservancy’s Director of Conservation Advocacy. “EPA has an obligation under Executive Order 13186, the Migratory Bird Treaty Act, and the Endangered Species Act to ensure that migratory birds are not harmed.” Many Latin American countries that currently use these pesticides export coffee, bananas, citrus crops, and other fruits and vegetables to the United States. Agricultural areas — in particular shade coffee farms — provide valuable habitat for migratory birds, and so pesticide use in these areas can pose a significant […]

Report Implicates Pesticides in Chesapeake Bay’s Decline

(Beyond Pesticides, July 31, 2009) A group of advocates and experts is warning that pesticide pollution from farm fields and households is contributing to the Chesapeake Bay’s decline, and may well be linked to declines in frogs across the region and intersex fish seen in the Potomac River. In a report released yesterday, the group calls on federal, state and local government to accelerate research into what threats pesticide contamination may pose to the bay, and to step up efforts to reduce such toxic pollution. “The thing that alarms us the most are the endocrine disruptors and the findings that have come out about intersex fish and frogs with reproductive problems,” said Robert SanGeorge, director of the Pesticides and the Chesapeake Bay Watershed Project. Endocrine disruptors are chemicals that mimic the natural hormones in humans or animals and can disrupt their growth and reproduction. The project is a partnership between the Maryland Pesticides Network and the Johns Hopkins Center for a Livable Future. The group’s warning and recommendations are the product of a two-year study, in consultation with scientists, public health experts, government officials, watermen, environmentalists, farmers and pest management industries. The report comes as federal and state governments attempt […]

EPA Initiates Review for Pesticide Linked to Honeybee Decline

(Beyond Pesticides, July 16, 2009) The U.S. Environmental Protection Agency (EPA) has issued a Final Work Plan (FWP) for the registration review of imidacloprid. A neonicotinoid insecticide, imidacloprid is highly toxic to honeybees on an acute exposure basis, and has been implicated in the recent Colony Collapse Disorder (CCD) that has occurred throughout the U.S. Over 12,000 comments were received by the agency since December 2008, urging the agency to suspend the use of this controversial chemical. Imidacloprid was first registered in the U.S. in 1994 as an insecticide to control a range of pests on crops, structures, indoor and outdoor residential areas, as well as pet products. While the use of imidacloprid has been gaining in popularity, its health and environmental effects have not been adequately studied. EPA, with its registration review program, pursuant to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) section 3(g), must review each registered pesticide every 15 years to determine whether it continues to meet the FIFRA standard for registration. The public docket for imidacloprid was opened in December 2008 and has since received over 12,000 comments, including those submitted by Beyond Pesticides, NRDC, the National Honey Bee Advisory Board (NHBAB) and Sierra Club, […]

Lawsuit to Challenge EPA for Pesticide Impacts on Polar Bears

(Beyond Pesticides, July 10, 2009) The Center for Biological Diversity notified the U.S. Environmental Protection Agency (EPA) earlier this week of its intent to file suit against the agency for failing to consider impacts to the polar bear and its Arctic habitat from toxic contamination resulting from pesticide use in the U.S. Pesticides registered by EPA for use in the U.S. are known to be transported to the Arctic via various atmospheric, oceanic, and biotic pathways. Such pesticides are biomagnified with each step higher in the food web, reaching some of their greatest concentrations in polar bears, the apex predators of the Arctic. A body of literature demonstrates the far-reaching effects of commonly used pesticides that are suspected endocrine disruptors and persistent organic pollutants, such as atrazine, 2,4-D, lindane, endosulfan, and permethrin, on global ecosystems. These pesticides, among others, and related contaminants have been linked to suppressed immune function, endocrine disruption, abnormalities in reproductive organs, hermaphroditism, and increased cub mortality in polar bears. Human subsistence hunters in the Arctic, who share the top spot on the food web with the polar bear, also face increased risks from exposure to these contaminants. “The poisoning of the Arctic is a silent crisis […]

EPA Proposes Pesticides Restrictions in Endangered Species Settlement

(Beyond Pesticides, July 6, 2009) Last week, the U.S. Environmental Protection Agency (EPA) proposed to formally evaluate the harmful effects of 74 pesticides on 11 endangered and threatened species in the San Francisco Bay Area over the next five years, and to impose interim restrictions on use of these pesticides in and adjacent to endangered species habitats. The proposal stems from a settlement agreement with the Center for Biological Diversity, which sued EPA in 2007 for violating the Endangered Species Act by registering and allowing the use of toxic pesticides in Bay Area endangered species habitats without determining whether the chemicals jeopardize those species’ existence. “Tens of millions of pounds of toxic and poisonous chemicals, known to be deadly to endangered species and harmful to human health, including proven carcinogens and endocrine disruptors, are applied in the Bay Area each year, and many of those find their way through runoff or drift into our soil, creeks and rivers, San Francisco Bay, and sensitive wildlife habitats,” said Jeff Miller, conservation advocate with the Center. “The toxic stew of pesticides in the Bay-Delta has played a major role in the collapse of native fish populations, and pesticides are a leading cause of […]

Secret Ingredient in the Herbicide Roundup Kills Human Cells

(Beyond Pesticides, July 1, 2009) Researchers have found that one of the so-called “inert” ingredients in the popular herbicide product Roundup can kill human cells, particularly embryonic, placental and umbilical cord cells. Over 4,000 inert ingredients are approved for use in the U.S. and can be mixed with pesticide “active” ingredients; however these chemicals are not disclosed to consumers or users on pesticide product labels due to EPA’s intepretation (many would say incorrect interpretation) of federal pesticide law. Many inerts are classified as highly toxic, while others have not been adequately studied. About 100 million pounds of Roundup are applied to U.S. farms and lawns every year and until now, most health studies have focused on the safety of glyphosate the active ingredient in Roundup, rather than the mixture of “inert” ingredients found in the herbicidal product. In this new study, “Glyphosate Formulations Induce Apoptosis and Necrosis in Human Umbilical, Embryonic, and Placental Cells,” researchers found that Roundup’s inert ingredients amplified the toxic effect on human cells””even at concentrations much more diluted than those used on farms and lawns, and which correspond to low levels of residues in food or feed. One specific inert ingredient, polyethoxylated tallowamine, or POEA, was […]

Scientists Study Children’s Susceptibility to Pesticides, Urge EPA to Act

(Beyond Pesticides, June 25, 2009) Although it is known that infants are more susceptible than adults to the toxic effects of pesticides, this increased vulnerability may extend much longer into childhood than expected, according to a new study by researchers at the University of California, Berkeley. Among newborns, levels of paraoxonase 1 (PON1), an enzyme critical to the detoxification of organophosphate pesticides, average one-third or less than those of the babies’ mothers. It was thought that PON1 enzyme activity in children approached adult levels by age two, but instead, the UC Berkeley researchers found that the enzyme level remained low in some individuals through age seven. Based upon the findings, reported in the journal Environmental Health Perspectives, the study authors recommend that the U.S. Environmental Protection Agency (EPA) re-evaluate the current standards for acceptable levels of pesticide exposure. “Current EPA standards of exposure for some pesticides assume children are three to five times more susceptible than adults, and for other pesticides the standards assume no difference,” said Nina Holland, Ph.D., UC Berkeley adjunct professor of environmental health sciences and senior author of the paper. “Our study is the first to show quantitatively that young children may be more susceptible to […]
