(Beyond Pesticides, October 10, 2013) A recent investigation into the death of thousands of bees last month in Minnesota revealed that fipronil, a widely used insecticide, was to blame. In mid-September, three colonies of bees in Minneapolis were found twitching and dying on the ground. Local apiarist Mark Lucas paints a grim picture of the poisoning event, which he witnessed, recalling that bees inside the hive came “spilling out of the hive as if they were drunk.” University of Minnesota Bee Lab, the University’s Bee Squad, and the Minnesota Department of Agriculture (MDA) carried out the  investigation, taking samples from hives to confirm pesticide poisoning. Indeed, MDA tests found that all three of the affected hives tested positive for the presence of fipronil. Although neonicotinoid pesticides such as clothianidin, thiamethoxam, and imidacloprid have been widely implicated in the phenomenon of colony collapse disorder (CCD), other pesticides are known to adversely affect honey bee health. Fipronil has also been heavily implicated in elevated bee toxicity and decline. Indeed, the European Union (EU) recently put forth a proposal to restrict the use of the pesticide in recognition of the high acute risks it poses to bees. The chemical is widely used for […]

(Beyond Pesticides, October 3, 2013) According to new research, residents are more highly exposed to organophosphate and pyrethroid pesticides in New York City (NYC) than in the U.S. overall.  Researchers from the city’s Department of Health and Mental Hygiene reviewed the 2004 NYC Health and Nutrition Examination Survey (NYC HANES) to compare its pesticide exposure patterns in an urban environment with the nation as a whole. The NYC HANES includes a biomonitoring component to evaluate pesticide exposures by measuring concentrations of organophosphate and pyrethroid metabolites in urine. According to the authors, the findings underscore the importance of considering pest and pesticide burdens on cities, where a dense population results in a single exposure source affecting many people at the same time when regulating pesticide use. Organophosphate metabolites were measured in the urine of 882 New Yorkers, while 1,452 residents were tested for pyrethroid metabolites. As the researchers explain, the building density and disrepair in parts of NYC likely increased the chances of a pest infestation, which in turn can lead to the reliance on indoor pesticide use. By the 1980’s, organophosphates were the most common class of insecticides in the U.S., and were used indoors until the early 2000’s when […]

(Beyond Pesticides, September 27, 2013) In an effort to ensure that the essential independent scientific research on pesticides is not thwarted by the chemical industry, Beyond Pesticides has launched The Fund for Independent Science. This fund, catalyzed by the recent announcement that Tyrone Hayes, Ph.D. has lost university funding for his laboratory and research, is set up and run by Beyond Pesticides. Our goal is to raise $150,000 to enable Dr. Hayes to keep his lab running for a year, and ultimately support the other work of independent researchers. Make a pledge today. There are few scientific research projects more important to protecting life and preventing its long-term demise than those conducted by Tyrone Hayes, Ph.D. And now this work is under threat. Dr. Hayes, a Harvard educated biologist and professor of Integrative Biology at the University of California, Berkeley, whose research finds that the herbicide atrazine feminizes male frogs, is one of the leading scientists critical of the pesticide industry and regulatory process.  This critical research is threatened while, as Dr. Hayes’ points out, amphibian species are in decline and they are disappearing. Read Protecting Life — From Research to Regulation: Disappearance of frogs, human health effects linked to […]

(Beyond Pesticides, August 15, 2013) Many “bee friendly” home garden plants sold at Home Depot (NYSE: HD), Lowe’s (NYSE: LOW) and other leading garden centers have been treated with pesticides shown to harm and kill bees, according to a pilot study released yesterday by   Friends of the Earth-US, Beyond Pesticides,  and others.  Supporting organizations sent a  letter  yesterday —along with petitions signed by more than 175,000 people— to Lowe’s, Home Depot, Target and other top garden retailers, asking the stores to stop selling neonicotinoids and plants treated with the pesticides. A majority of the UK’s largest garden retailers, including Homebase, B&Q and Wickes, have already stopped selling neonicotinoids. The pilot study, co-authored by the Pesticide Research Institute, found that 7 of 13 samples of garden plants purchased at top retailers in Washington DC, the San Francisco Bay Area and Minneapolis contain neurotoxic pesticides known as neonicotinoids that studies show harm or kill bees and other pollinators. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. These systemic pesticides, which  move through the plant’s vascular system and express themselves through pollen […]

(Beyond Pesticides, August 12, 2013) A recent study on triclosan, an antibacterial pesticide found in soaps, deodorants, toothpastes, cosmetics, fabrics, plastics, and toys, finds that exposure changes the composition of bacterial communities in streams and also increases bacterial resistance. The study contributes to continually mounting evidence demonstrating that triclosan is toxic to human health and the environment, even as the U.S. Environmental Protection Agency (EPA) gets ready to review the registration of the chemical. In May, EPA initiated the registration review of triclosan, an antibacterial pesticide that has been heavily scrutinized by concerned groups, including Beyond Pesticides, as well as members of Congress. Under pressure after its 2008 review, EPA announced that it would again review triclosan in 2013, five years earlier than scheduled. Over the last few years, as a direct result of pressure from consumer groups and the media regarding the need for triclosan in consumer products and the mounting scientific evidence documenting adverse health effects, including impacts to the thyroid hormone, major manufacturers have begun to quietly reformulate their products without triclosan. This study, published in the journal Environmental Science and Technology, took several field and artificial stream surveys, to identify the effects of triclosan on bacterial […]

(Beyond Pesticides, August 1, 2013) The House of Representatives Appropriations Interior and Environmental subcommittee voted Tuesday 7-4 to approve an appropriations bill that would cut the budget of the U.S. Environmental Protection Agency (EPA) by nearly a third, and includes language that would prevent the agency from enforcing its decision to phase out the use of the neurotoxic fumigant sulfuryl fluoride in our food. The full Appropriations Committee began markups on Wednesday, and, if it passes it will move to a House vote. This is an outrageous attempt to circumvent a basic risk assessment calculation that EPA acknowledges puts the public at risk, given current exposure patterns, to a chemical that is especially hazardous to children. In response to this egregious attempt to stop EPA from doing its job, Beyond Pesticides, along with Environmental Working Group and Fluoride Action Network submitted a letter to the House Appropriation Committee Chairman and Ranking members: Dear Chairman Rogers and Ranking Member Lowey: On behalf of our members and supporters we urge you to strike section 449 from the House Fiscal Year 2014 Interior and Environment Appropriations Act. This section will prohibit the U.S. Environmental Protection Agency from fulfilling its decision to phase-out sulfuryl […]

(Beyond Pesticides, July 30, 2013) A recent study published in Environmental Toxicology and Chemistry found levels of pesticide contamination from agricultural drift in Pacific Tree frogs in remote mountain areas including national parks. The study supports past research on the pesticide transport through atmospheric dust and rain. To conduct the study, researchers collected Pacific Chorus frogs, as well as water and sediment samples, from seven ponds ranging from Lassen Volcanic National Park at the northern most location of Central Valley to the Giant Sequoia National Monument. The samples were tested for 98 types of pesticides, traces of which were found in frog tissues from all sites. Two fungicides, pyraclostrobin and tebuconazole, and one herbicide, simazine, were the most frequently detected compound. This was the first time these compounds have ever been reported in wild frog tissues. According to the study, chemical concentrations are often higher in the frog tissue than the environment. This happens as frogs store up small exposures over time, allowing pesticides to bioaccumulate in their bodies. Exposure to pesticides can decrease frog’s immune system and increase their risk of disease. Continual pesticide exposure has led to dramatic declines in amphibian populations. Amphibians are considered the most threatened […]

(Beyond Pesticides, July 26, 2013) Thousands of people from across the country took action last month to prevent Dow AgroSciences from using its influence to insert Farm Bill language that would allow the food uses of the pesticide sulfuryl fluoride to continue, despite a U.S. Environmental Protection Agency (EPA) proposal to phase it out. Dow’s latest attempt to keep this neurotoxic fumigant in our food is to defund EPA’s ability to regulate its use. Language inserted into the 2014 Interior and Environment House Appropriations Bill will prevent EPA from enforcing its previous decision to phase out the use of sulfuryl fluoride. Tell Your Representative Today: Remove Section 449 from the House Appropriations Bill. According to Section 449 on sulfuryl fluoride, none of the funds made available in the appropriations bill may be used by EPA “that in any way removes, withdraws, revokes, or stays tolerances for the pesticide chemical sulfuryl fluoride if that final order takes into consideration aggregate or cumulative exposure to other substances related to sulfuryl fluoride or its metabolites or degradates.” This will essentially prevent EPA from doing the job Congress assigned to the agency under the Federal Food, Drug, and Cosmetic Act, which requires that EPA […]

(Beyond Pesticides, July 22, 2013) Organophosphate pesticide poisoning from contaminated school lunches is suspected as the cause of deaths for at least 25 children in India. The children, aged four to 12, became sick after eating a lunch provided to them by the school. Several reports suggest the rice or cooking oil used to prepare the food contained unsafe levels of organophosphates, a highly toxic class of pesticides that have the same mechanism of action as nerve gasses. In the U.S. most organophosphates pesticides were phased out of residential use; however, these neurological poisons are still widely used on agricultural crops and for mosquito control. The schoolchildren began fainting soon after eating the contaminated food, and within hours at least 25 children were pronounced dead. Authorities discovered a container of organophosphate pesticides next to the cooking oil, but were not able to determine if this was the source of the poisoning or if the food itself was tainted with organophosphates. The school cooks, who both had children at the school that either fell ill or died from eating the food, told authorities that the cooking oil appeared different than usual, but the principal told them to use it anyway. The […]

(Beyond Pesticides, July 18, 2013) A few months after the groundbreaking decision to suspend the use of three neonicotinoids shown to be highly toxic to bees, the European Commission is moving forward again with a proposal to restrict the use of the insecticide fipronil, which has also   been identified as posing an acute risk to honey bees. The proposal is backed by a Member State experts meeting in the Standing Committee on Food Chain and Animal Health. This proposal follows a European Food Safety Authority (EFSA)  scientific risk assessment, published on May 27, 2013, which found that seeds treated with pesticides containing fipronil pose an acute risk to Europe’s honey bee population. According to this assessment, it was found that fipronil poses a high acute risk to honeybees when used as a seed treatment for corn. Specifically, EFSA concluded that high acute risk from dust drift resulting from treated corn exists, and identified several data gaps and study limitations for other field crops. Data on nectar and pollen could not be evaluated. 23 Member States supported the fipronil restriction, 2 Member States voted against and 3 Member States abstained during the standing committee vote. This latest EU-wide restriction comes […]

(Beyond Pesticides, July 12, 2013) New research concludes that exposure to a combination of both arsenic and estrogen, at levels U.S. Environmental Protection Agency (EPA) considers “safe” for humans, can cause cancer at elevated levels in prostate cells. Texas Tech University researchers revealed that humans exposed to a combination of both toxicants were almost twice as likely to develop cancerous cells in their prostate. The study is published in the peer-reviewed journal The Prostate. While it is established that both arsenic and estrogen can cause cancer, the research raises concerns about the dangers of chemicals in combination, and the efficacy of regulations that are established by testing one chemical at a time. Kamaleshwar Singh, PhD., is an assistant professor at the Institute of Environmental and Human Health at Texas Tech. “The majority of cancers are caused by environmental influences,” Dr. Singh remarked to Texas Tech Today, “Only about 5 to 10 percent of cancers are due to genetic predisposition. Science has looked at these chemicals, such as arsenic, and tested them in a lab to find the amounts that may cause cancer. But that’s just a single chemical in a single test. In the real world, we are getting exposed […]

(Beyond Pesticides, June 28, 2013) The U.S. Environmental Protection Agency (EPA) released a draft “State of the Science” report last week acknowledging that low dose responses “do occur in biological systems” while defending its current risk assessment procedures as adequate for evaluating low dose effects. This report comes after EPA’s long running failure to fully implement a 1996 Congressionally mandated program to evaluate endocrine disruptors, and heavy criticism last year from prominent scientists who said EPA’s testing procedures are outdated. In 1999 the Natural Resources Defense Council (NRDC) filed a lawsuit against the EPA for failing to meet a statutory deadline for implementation of the Endocrine Disruptor Screening Program (EDSP) required under the 1996 Food Quality Protection Act, forcing the EPA to make a settlement agreement. As a result of  NRDC et al. v. EPA (No. C-99-03701 CAL) filed in the Northern District of California, EPA agreed to start requiring screening and testing of certain chemicals varying by date, using a tiered system. EPA’s two-tiered screening and testing system, requires that EPA will identify which chemicals are able to interact with the endocrine system in Tier 1. Tier 2 screening process was designed to go one step further, requiring EPA […]

(Beyond Pesticides, June 21, 2013) A scathing new investigative report shows that atrazine manufacturer, Syngenta Crop Protection, launched an aggressive multi-million dollar campaign in response to a class action lawsuit that threatened to remove the controversial herbicide atrazine  from the market. The report reveals that the pesticide giant routinely paid “third-party allies” to appear to be independent supporters, keeping a list of 130 people and groups it could recruit as experts without disclosing ties to the company. The company, the report finds,  also purportedly hired a detective agency to investigate scientists on a federal advisory panel, looking into the personal life of a judge and commissioning a psychological profile of Tyrone Hayes, PhD, one of the leading scientists critical of atrazine, whose research finds that atrazine feminizes male frogs. Recently unsealed court documents reveal a corporate strategy to discredit critics and to strip plaintiffs from the class action case. 100Reporters, a nonprofit investigative journalism group, obtained the documents from the lawsuit in a Freedom of Information Act (FOIA) request. The campaign is spelled out in hundreds of pages of memos, invoices, and other documents from the  Illinois’ Madison County Circuit Court, which were initially sealed as part of a 2004 […]

(Beyond Pesticides, June 19, 2013) The Director of the National Institute of Environmental Health Sciences (NIEHS), Linda Birnbaum, PhD, is being criticized by some Republicans for authoring an article that describes linkages between endocrine disrupting chemicals and the onset of disease, as well as the need to understand and monitor the effects of these chemicals. Instead of encouraging efforts for greater understanding of these chemicals, the members of Congress instead blasted the article as a potential breach of National Institutes of Health (NIH) policy. NIEHS, a program of NIH, seeks to reduce the burden of human illness and disability by understanding how the environment influences the development and progression of human disease. The short article entitled, “When environmental chemicals act like uncontrolled medicine,” published online on May 7, 2013, in Trends in Endocrinology and Metabolism, lays out the case that environmental chemicals can produce unwanted endocrine effects, leading to an increase in certain diseases.  It states, “In the same way as physicians endeavor to understand and monitor the effect of medicines on endocrine pathways, we ought to achieve the same understanding and control of the effects on environmental chemicals.” Dr. Birnbaum also notes, “The proliferation of inadequately tested chemicals in […]

(June 10, 2013, Beyond Pesticides) The Washington State Department of Agriculture (WSDA) on June 6 rejected a petition by Thurston County Commissioners to restrict sale, use and application of neonicotinoid insecticides. On April 8, 2013, the Commissioners requested the action by WSDA because of concerns about the effect of neonicotinoid insecticides on honey bee colony health. The Commissioners were acting on “substantial bee colony loss in 2012” reported by the Olympia Beekeepers Association. In its request, the Commissioners asked the state to implement a “restriction on the purchase, sale, distribution and application of the neonicotinoid class of insecticides for ornamental use to persons or entities with a valid WSDA pesticide applicator license” and indicated that “immediate action on a local level is appropriate and necessary.” Beyond Pesticides wrote a letter of support in favor of the petition. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. According to the EPA, uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they […]

(Beyond Pesticides, May 15, 2013) Recent public outcry over atrazine contamination of drinking water supplies on Long Island has pressured pesticide, herbicide, and fungicide manufacturer Makhteshim Agan of North America (MANA) to restrict the sale, use, and distribution of the toxic chemical. The move has been lauded by environmental advocacy groups, including Citizens Campaign for the Environment (CCE). “Atrazine is a dangerous chemical that poses an unacceptable risk to public health and the environment on Long Island,” said Adrienne Esposito, CCE Executive Director. “Removing this product from the shelves is an essential first step in protecting Long Island drinking water from unnecessary pesticide contamination. We are delighted by this news.” Unfortunately, stores will continue to sell its atrazine inventory until MANA implements the anticipated restriction date of spring of 2014. Atrazine is one of the most commonly used herbicides in the world and is used on most corn, sugarcane and sorghum acreage in the United States; and can also be used on golf courses and residential lawns. In the U.S. alone, 60-80 million pounds are used per year to stop pre- and post-emergent broadleaf and annual grassy weeds, and is generally applied in the spring. The herbicide is a common […]

(Beyond Pesticides, May 13, 2013) According to preliminary results of a survey by the Bee Informed Partnership, 31.1 percent of managed honey bee colonies in the U.S. were lost during the 2012/2013 winter.   Though these preliminary loss reports are similar to the past six year average of 30.5 percent, the new loss numbers represent a 42 percent increase compared to the previous winter. Survey participants indicate that they consider a loss rate of 15 percent as “acceptable,” but 70 percent of participants suffered losses greater than this. With continued winter bee losses of over 30%, and concern whether there will be enough bees to pollinate U.S. crops this year, beekeepers and environmentalists say it is imperative  that regulators act by banning the neonicotiniod pesticides that have been implicated in the global decline of honey bee populations. In addition to this national report, several state level incidents of large scale honey bee colony losses have been reported. In a recent incident in Florida, citrus groves experienced an acute foliar poisoning that resulted in severely damaged colonies. Oranges had an early bloom this year, and were still blooming near the end of April. One beekeeper’s colonies suffered immense losses due to […]

(Beyond Pesticides, May 10, 2013) The U.S. Environmental Protection Agency (EPA) published on May 8 a final rule to revise and update use patterns and data requirements for antimicrobial pesticides. Though the new rule is the first revision to EPA data requirements for antimicrobial pesticide registrations since 1984,   remaining inconsistencies among data submissions and data gaps, these new rules are a step in the right direction when it comes to regulating antimicrobial pesticides, considering the proliferation of consumer products that contain these chemicals. However, even with these new rules in place, certain antimicrobial pesticides that are already in consumer products, such as triclosan, will  still present serious hazards for  human and environmental health. More than 5,000 antimicrobial products are currently registered with EPA. Initially designed for hospitals and clinics, many antimicrobial pesticides are found in products ranging from household cleaners to mattresses and bedding, cosmetics, toys, toothpaste and even chopsticks. Antibacterial products are being marketed to the health conscious without firm evidence of real benefits and amid growing concern about unintended externalities. One prime example of this is triclosan, which is formulated into hundreds of personal care products, toys and textiles. Studies show that triclosan is an endocrine disruptor, […]

(Beyond Pesticides, April 24, 2013) Using the aquatic species Daphnia, commonly referred to as “water fleas,” scientists at North Carolina State University (NC State) determined that exposure to the pesticide pyriproxyfen impacted multiple generations, ultimately resulting in more male offspring, and causing reproductive problems in female offspring. Lead author Gerald LeBlanc, PhD, notes, “This work supports the hypothesis that exposure to some environmental chemicals during sensitive periods of development can cause significant health problems for those organisms later in life —and affect their offspring and, possibly, their offspring’s offspring.” The study, published in the journal PLoS One, provides the scientific community with new information on how organisms respond to the environmental signals resulting from pesticide exposure. Environmental cues normally determine whether the Daphina offspring will be male or female, according to the researchers. This study is part of an investigation to understand the mechanisms involved with these environmental cues. The NC State team had previously identified the hormone methyl farnesoate (Mf) as an important factor in determining the sex of the organisms at the embryotic stage. The scientists exposed Daphnia to varying levels of the pesticide pyriproxyfen, an insecticide that mimics the Mf hormone. The exposure resulted in Daphnia producing […]

(Beyond Pesticides, April 9, 2013) Last Wednesday, close to a hundred people attended a public hearing at the Riverhead campus of Suffolk County Community College, sponsored by the Department of Environmental Conservation (DEC), to comment on the draft of the Long Island Pesticide Pollution Prevention Strategy. The strategy, which was released in January, is dramatically different than a draft plan DEC had released in 2011. The draft plan had initially received praise from environmental organizations for its “zero tolerance policy”   to ensure certain chemicals did not end up in Long Island’s drinking water. However, the revamped strategy fails to offer any meaningful protective measures or strong pesticide regulations. This is concerning, given trace amounts of metalaxyl, imidacloprid and atrazine have been repeatedly detected in test wells, along with 117 other pesticides detected in Long Island drinking water. State officials argued that pesticide levels in Long Island’s drinking water are far below federal standards. However, the pesticides that have been found in the drinking water have been linked to several health and environmental problems. Because of these health and environmental risks the Citizens Campaign for the Environment, a grassroots organization working in Long Island, has called for DEC to ban […]

(Beyond Pesticides, March 1, 2013) In a literature review published in Toxicology last week, researchers found that environmental and occupational pesticide exposure was strongly associated with declines in sperm count. Researchers Sheena Martenies, BS, and Melissa Perry, ScD., MHS., determined that of the 17 studies evaluated, 15 of them reported significant associations between pesticides and semen quality. The researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. Researchers targeted studies on DDT, HCH, and abamectin, grouping pyrethroids and organophosphates by class. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies””only two indicated any changes to sperm shape. These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health. In addition to the U.S. findings,  studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50% between 1940 and 1990, no small amount. These results might not be surprising as […]

(Beyond Pesticides, February 20, 2013) A new report by the United Nations Environment Programme (UNEP) and the World Health Organization (WHO) has identified endocrine disrupting chemicals as having significant health implications for the global population. According to the report, these chemicals have the capacity to interfere with tissue and organ development and function, and therefore they may alter susceptibility to different types of diseases throughout life, and represents a global threat that needs to be resolved. The report cites insufficient reporting and information on chemicals in products, materials and goods and calls for more research and collaboration. The State of the Science of Endocrine Disrupting Chemicals,   a joint study by UNEP and WHO, finds that endocrine disrupting chemicals (EDCs) are important environmental risk factors for endocrine diseases. Exposures during critical phases of development play an important role in the onset of many diseases, affecting future generations. Trends indicate an increasing burden of certain endocrine diseases across the globe, and it is clear from human studies that populations are exposed to perhaps hundreds of environmental chemicals at any one time. This UN study, which is the most comprehensive report on EDCs to date, highlights some association between exposure to EDCs […]
