(Beyond Pesticides, August 21, 2013) Suffolk County, New York, Legislator Jay Schneiderman (I-Montauk) introduced a bill on July 30, 2013 to establish strict guidelines for the use of methoprene within estuaries in Suffolk County.   Methoprene, an insect growth regulator, is commonly used in mosquito control programs, but is highly toxic to estuarine invertebrates, including crabs and lobsters, which are the backbone of the fishing industry along the East coast. This bill follows similar legislation already passed in Connecticut and Rhode Island to help protect lobster populations. The lobster population in the Long Island Sound has decreased dramatically over the last decade, corresponding with the introduction of pesticides such as methoprene in mosquito control programs. Methoprene  is an insect growth regulator that prevents development to the adult reproductive stages so that insects die in arrested immaturity. It is an insecticide that is acutely toxic to estuarine invertebrates, including valuable food and commercial species like crabs and lobsters.  The effect of mosquito pesticides on marine life, especially lobsters, has come under scrutiny in recent years as mosquito spray programs in various states escalated efforts to suppress West Nile virus (WNv). Other mosquito-killing chemicals suspected of causing damage to aquatic life include […]

(Beyond Pesticides, August, 2, 2013) A new study published in the American Journal of Epidemiology concludes that farmers using herbicides are nearly two and a half times as likely to be treated for depression as those who did not use herbicides. Furthermore, farmers who are exposed for greater periods of time are also afflicted with greater risk of developing depression, raising concerns of the harm chemicals can cause to mental health. Building on substantial research supporting the link between pesticide exposure and neurological damage, this study examines the role that pesticides play in the overall health of farmers, and gives further weight to the importance of choosing organic food. Researchers surveyed 567 farmers from France, questioning them on the frequency of their use of fungicides, insecticides, and herbicides, to determine how pesticide exposures were linked to the risk of developing clinical depression. Lead researchers and associate professor at the Harvard School of Public Health, Marc Weisskopf, PhD, said while the results are unclear, they “suggest we should not be ignoring herbicides just because they’re targeting plants.” Previous research has already suggested that pesticides, particularly organophosphates, cause a variety of serious neurological health problems, including Parkinson’s disease. This is not surprising, […]

(Beyond Pesticides, July 29, 2013) Researchers at the U.S. Department of Agriculture (USDA) and University of Maryland have found that low levels of pesticide exposure from crop pollination make honey bees more susceptible to the deadly gut parasite, Nosema ceranae, contributing to declines in bee populations. The study’s findings, released Wednesday July 24 in the journal PLoSONE, expand on a recent report released by the USDA that found parasites, disease, genetics, poor nutrition, and pesticide exposure as synergistic factors in the observable nationwide honey bee decline, but focused on technological stopgap measures without questioning the  sustainability of widespread systemic neonicotinoid pesticide use.  Adding urgency to USDA’s research, another study released just last Monday in the Proceedings from the National Academy of Sciences shows that pollinator losses can have a detrimental effects on plant reproduction. Pesticide Exposure and Susceptibility to Disease The newest USDA research adds to the growing body of evidence that shows pesticide exposure weakens honey bees’ immune system making them more susceptible to parasites and pathogens. Researchers took pollen samples from crops that honey bees are known to pollinate including apples, watermelons, pumpkins, cucumbers, blueberries, and cranberries to determine exposure levels and Nosema infection. In sum, researchers found […]

(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 19, 2013) A recent report by the U.S. Geological Survey (USGS) examines the health of the nation’s streams over 20 years and finds that streams nationwide are severely degraded by humans, exhibiting elevated levels of pesticides and nutrients as well as streamflow modifications. Overall, the report finds that 83 percent of streams in agricultural and urban areas contain at least one aquatic community that was altered, or in other words, negatively affected. With waterways in the U.S. increasingly imperiled from various agents including agricultural and industrial discharges, nutrient loading (nitrogen and phosphorus), and biological agents such as pathogens, assessments such as these provide further impetus to protect water quality for both human health and the environment. The report, entitled “Quality of Our Nation’s Waters: Ecological Health in the Nation’s Streams, 1993-2005,” describes the health of three biological communities ””algae, macroinvertebrates, and fish”” to  measure the overall quality of streams. A stream’s ability to support these community structures can directly measure the health of waterways. The report assesses streamflow modifications and measures over 100 chemical constituents in water and streambed sediments. The report is a comprehensive assessment of the variety of factors that contribute to stream health declines, […]

(Beyond Pesticides, July 9, 2013) A recent pesticide contamination incident in Great Britain’s Kennet River has decimated aquatic invertebrate populations on a ten mile stretch of river between the towns of  Marlborough and Hungerford. The contamination occurred after a spill of the toxic pesticide chlorpyrifos entered a Marlborough sewage system. The lack of aquatic invertebrates could lead to a dramatic decline of the river’s chalk trout population. A similar incident occurred in Great Britain on the Wey River in 2003, and in Sussex Ouse in 2001. This recent calamity helps to underscore the importance for the U.S. Environmental Protection Agency (EPA), across the Atlantic, to fully implement pesticide restrictions that U.S. conservation groups are seeking to enforce through court action. The damage to the U.K. river may have been caused by, according to an Express article, only two tablespoons of the neurotoxic insecticide chlorpyifos. Members of the public have been advised by Britain’s Environment Agency to avoid skin contact with the water and not to eat fish caught from the river.  The contamination has occurred at the height of fly-fishing season. Environmental organizations are afraid that a decline in the number of aquatic invertebrates could lead chalk trout and other […]

(Beyond Pesticides, July 2, 2013) In the wake of massive bee kills, the Oregon Department of Agriculture (ODA) is placing temporary restrictions on the use of pesticides with the active ingredient dinotefuran. Dinotefuran, a neonicotinoid pesticide, was confirmed as the cause of one massive bee die-off in Wilsonville, Oregon, and suspected as the cause of another bee die off in Hillsboro, Oregon. This temporary restriction will be in place for 180 days for a limited number of dinotefuran uses. Environmental advocates have sued EPA  on neonicotinoid  pesticides, citing its regulatory process  as deficient in  protecting bees and other beneficial organisms. Just as Pollinator Week 2013 began, an estimated 50,000 bumblebees, likely representing over 300 colonies, were found dead or dying in Wilsonville. According to the Xerces Society, this was the largest known incident of bumblebee deaths ever recorded in the country. After a preliminary investigation, ODA confirmed that the massive bee die-off was caused by the use of the insecticide dinotefuran. Then, it was reported by The Oregonian that hundreds of bees were found dead after the same pesticide was used in the neighboring town of Hillsboro. Dan Hilburn, director of plant programs at the Oregon Department of Agriculture (ODA), […]

(Beyond Pesticides, June 26, 2013) Pesticide use has sharply reduced the regional biodiversity of stream invertebrates, such as mayflies and dragonflies, finds a study published in the Proceedings of the National Academy of Science. While previous research has shown similar decreases in individual streams, this new study analyzes the effects of pesticides over broad regions. This is one of several recent findings that show pesticides pose a long-term threat to important ecosystems. The study, entitled Pesticides reduce regional biodiversity of stream invertebrates, notes that losses of biodiversity caused by anthropogenic activities during the past 50 years are unprecedented in human history. A team of researchers sampled 23 streams in the central plains of Germany, 16 in the western plains of France, and 24 in southern Victoria, Australia. Researchers classified streams according to three different levels of pesticide contamination: uncontaminated, slightly contaminated, and highly contaminated. Utilizing a model-based approach to account for other environmental variables, the team observed that losses in taxonomic diversity were, to a large degree, determined by the loss of species specifically vulnerable to pesticides. Overall, they found that there were up to 42% fewer species in highly contaminated than in uncontaminated streams in Europe. Highly contaminated streams […]

(Beyond Pesticides, June 18, 2013) Neonicotinoid pesticides have broad ranging negative impacts not only on beneficial pollinators, but on overall biodiversity and ecosystem health, according to a new study published in the Journal of Applied Ecology. The study, conducted by David Goulson, Ph.D, of the University of Sussex, provides a detailed overview of the current literature on the economic and environmental risks of neonicotinoid pesticides. Dr. Goulson’s work draws stark and disturbing conclusions about the environmental fate of these systemic insecticides. First introduced in the early 1990’s as an alternative to the acutely toxic organophosphate and carbamate classes of  pesticides, neonicotinoids are now the most widely used insecticides in the world. They can be broadly applied as a spray or soil drench, however, the ability of these chemicals to translocate into a plant as it grows has led to the creation of a large market within conventional agriculture for seeds coated with these pesticides. As Dr. Goulson notes, global acceptance of treated seeds has undermined the adoption of alternative methods of conventional pest control, even  integrated pest management (IPM), which can reduce pesticide reliance  through monitoring and biological, structural, and cultural strategies. Instead, the treated seed market pushes farmers toward […]

(Beyond Pesticides, May 30, 2013) New research published in the journal Neurology further supports the causative link between pesticide exposure and Parkinson’s disease. Emanuel Cereda, M.D., Ph.D., of the IRCCS university Hospital San Matteo Foundation in Pavia, Italy, and coauthor Gianni Pezzoli, M.D., analyzed 104 studies published between 1975 and 2011 to determine the link between pesticides and solvents to Parkinson’s disease. The researchers analyzed exposure using information on proximity to large farms likely to use pesticides, likelihood of well water consumption, and occupations that cause greater exposure to pesticides and solvents used to kill weeds, insects, fungus, and rodents. Overall, researchers found exposure to pesticides increased the risk of developing the disease by 33%  to 80%.   Some pesticides were considered to be of higher risk than others, with weed killers like paraquat and fungicides maneb and mancozeb causing twice the risk for development of Parkinson’s disease. While risk increased the longer people were exposed to pesticides, researchers indicate there is still a need for further research on the chemical threshold for harm to the brain. The study builds on recent research that has linked Parkinson’s disease to pesticide exposure. In a 2011 article published in the journal Molecular […]

(Beyond Pesticides, May 21, 2013) The Centers for Disease Control (CDC) recently concluded that 2012 was the deadliest year for West Nile Virus (WNv) in the United States. “A total of 5,674 cases of West Nile virus disease in people, including 286 deaths, were reported to CDC from 48 states (excluding Alaska and Hawaii),” said the CDC in a statement. While it is still too early to determine whether this year will be as bad as last year’s outbreak (experts say the largest disease outbreaks  is strongly driven by weather patterns characterized by hot wet summers), one thing is certain: There are simple mosquito control techniques that can be performed in your community and backyard that will prevent the spread of WNv and nuisance biting mosquitoes without the use of highly toxic pesticides. Beyond Pesticides fielded calls from concerned residents across the U.S. whose communities were doused with pesticides in attempts to control WNv. Yet, these controls have been shown to be ineffective at managing mosquito populations. According to David Pimentel, PhD, professor emeritus of entomology at Cornell University, less than .0001% of adulticides (mosquito insecticides) reach target adult mosquitoes. Dr. Pimentel notes, “Thus by both ground and aerial application […]

(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, March 29, 2013) Two studies released Wednesday support the findings of the European Food Safety Authority that neonicotinoid insecticides pose an unacceptable risk to bees. The pair of British studies indicate that neonicotinoids and miticides cause brain damage, compromising bee survival. The study, published in Nature Communications by researchers at the University of Dundee and Newcastle University, concludes that imidacloprid  and clothianidin, a commonly used insecticides on crops and plants, as well as the organophosphate miticide coumaphos, a treatment for Varroa bee mites, cause cognitive damage in bees. The research indicates that within 20 minutes of exposure to pesticides the neurons in the learning center of the brain stop firing, causing “epileptic type” hyperactivity. While the bees are still alive, the lobes of the brain fail to communicate with each other with obvious implications for their survival, Another study, published in the Journal for Experimental Biology by a team of Newcastle scientists, links imidacloprid and coumaphos to learning and memory impairment. The research indicates that brain damage from pesticides makes it more difficult for bees to forage and find food, and when they find the food they have trouble locating and returning to their hives. In sum, the […]

(Beyond Pesticides, March 26, 2013) Scientists are learning more about the mechanisms bed bugs have developed to increase their resistance to the increasingly common class of pyrethriod pesticides. The study, published in the journal Scientific Reports in early March, adds further weight to calls from consumer health and environmental groups to adopt proven, non-toxic strategies to manage bed bugs and other household pest problems. After all, if alternatives exist, why put your family at risk with unsustainable, ineffective control methods? This latest research reveals something scientists had not suspected. Bed bugs are developing most of their resistance-associated genes on the outer layer of their shell. These genes either neutralize the insecticides before they can take effect, or slow down the toxins’ move towards the insects’ nerve cells. In addition, bed bugs in the study also show resistance developing within their nerve cells, the target site for the pesticides. This multilayered resistance is unique, scientists say, but, as Beyond Pesticides has long documented, pest resistance to pesticides is not. A 2011 study from Ohio State University reveals bed bugs’ ability to evolve hereditary changes in their production of certain enzymes, allowing them to excrete the toxins without being harmed. A study […]

(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 21, 2013) On February 6, the U.S. Environmental Protection Agency (EPA) released its preliminary volatilization assessment for the registration review of chlorpyrifos, finding that vapor phase chlorpyrifos may be emitted from treated fields at levels resulting in exposure to children and others who live, work, attend school, or otherwise spend time nearby.  In some circumstances, these bystanders may be exposed to chlorpyrifos and/or the transformation product chlorpyrifos-oxon at concentrations that could cause adverse effects. Citing uncertainties, the agency is requesting comments by March 8, 2013 on the potential risks to children and other bystanders from volatilization of chlorpyrifos from treated crops. EPA’s preliminary volatilization assessment is also in response to a petition filed by the Natural Resources Defense Council (NRDC) and the Pesticide Action Network North America (PAN) in 2007, which requested that the agency revoke all tolerances and cancel all registrations for chlorpyrifos. In a letter to NRDC and to PAN dated January 25, 2013, updating these groups on EPA’s response to their September 12, 2007 joint petition regarding chlorpyrifos, EPA stated that, “This assessment represents a significant advancement in the evaluation of pesticide risks, as it will be the first probabilistic assessment of the risks […]

(Beyond Pesticides, January 31, 2012) A new study finds that a mother’s exposure to pesticides before, during and after pregnancy may increase the risk of infant leukemia diagnosed before the age of two. Researchers in Brazil found that children are twice as likely to develop the rare cancers if their mothers were exposed three months before conception when compared to mothers who reported no exposures. A mother’s exposure at any time to the insecticide permethrin also raised the cancer risk for infants. The results support recommendations for women of reproductive age to minimize their pesticide exposure before and during pregnancy and while breastfeeding, and adds to the growing weight of evidence of the dangers of using synthetic pyrethroid pesticides. The study, entitled, “In utero pesticide exposure and leukemia in Brazilian children less than 2 years of age,” is published in Environmental Health Perspectives. Researchers asked mothers in Brazil about their pesticide exposure three months before pregnancy, while pregnant and three months after pregnancy when they were nursing. The women reported their home, work and agricultural contact with pesticides (at least once) between 1999 and 2007. Pesticide exposures from mothers of 252 children younger than two years old and diagnosed with […]

(Beyond Pesticides, January 15, 2013)  Research published in the journal Environmental Monitoring and Assessment calls into question the value of environmental monitoring, such as water sampling,  on a  fixed date schedule (i.e., once per month), finding that this approach underestimates actual risks. These findings could have a significant impact on how we assess the safety of both endangered species and drinking water supplies. Researchers explain that, although insecticides are applied less often than herbicides and fungicides, they are usually applied in very large amounts when used in response to acute insect infestations. Scientists found that monitoring for insecticides at pre-set intervals, even weekly or daily, did not detect the occurrence of peak concentrations for these chemicals. Co-author of the study, Ralf Shulz, PhD, explains, “Accordingly, by way of example, on the basis of weekly monitoring of a typical agricultural stream none of the total of six insecticide concentration peaks per year described by model calculations is found. Daily sampling detects only two of the six peaks. Only event-related sampling enables the detection of all these peaks.” Authors of the study point to the need for events-related sampling, both to ensure more accurate detections are taken and to reduce costs. Events-related […]

(Beyond Pesticides, January 11, 2012) Environmentalists, farmworkers, and farmworker advocates have become increasingly uncomfortable with the new proposal for pesticide safety measures which does not include details on how the proposed rule will protect agricultural workers, farmers, and applicators. These sentiments stem from the concern that this may mean less stringent regulations than those originally proposed. In 2010, the U.S. Environmental Protection Agency (EPA) released a   document proposing Worker Protection Standards (WPS) that would determine ways to increase training, improve safety requirements, provide clear emergency information, and create strong protection for applicators. However, a recent EPA handout distributed  during a November 2012 Pesticide Program Dialogue Committee (PPDC) meeting downplays the details within those goals, and brings into question the agency’s  previous commitments. Advocacy groups have raised pointed complaints on the new document’s prose: “I have to agree that we are just really in the dark,” said one environmental group lawyer, “It is mysterious that it’s taken them so long to come up with a draft to propose, and the fact that they are being kind of tight-lipped about it and that even the very minimal detail about the proposal that was in the 2010 document disappeared from the 2012 […]

(Beyond Pesticides, December 10, 2012) Long-term low-level exposure to organophosphate pesticides produces lasting damage to neurological and cognitive functions, according to researchers at University College London (UCL). This research pulls data from 14 studies over the past 20 years, including more than 1,600 participants, in order to provide a quantitative analysis of the current literature on these dangerous chemicals. Lead author of the study, Sarah Mackenzie Ross, Ph.D., notes, “This is the first time anyone has analyzed the literature concerning the neurotoxicity of organophosphate pesticides, using the statistical technique of meta-analysis.” UCL’s systematic review, published in the journal Critical Reviews in Toxicology, comes to an unsettling conclusion about the hazards of constant low-level occupational exposure to organophosphates. The study notes, “The majority of well designed studies found a significant association between low-level exposure to [organophosphates] and impaired neurobehavioral function which is consistent, small to moderate in magnitude and concerned primarily with cognitive functions such as psychomotor speed, executive function, visuospatial ability, working and visual memory.” In other words, low-level exposure had significant detrimental effect on working memory and information processing. The researchers are hopeful that the results of their analysis will be used to inform governments performing reviews on the […]

(Beyond Pesticides, December 6, 2012) A study published in the December issue of Annals of Allergy, Asthma and Immunology finds that exposure to dichlorophenols may be associated food allergies. Dichlorophenols are used as an intermediary in the manufacturing of some of the most commonly used pesticides, such as 2,4-D, and are also used to chlorinate drinking water. This study may help explain in part why food allergies are on the rise in the U.S. and already affect 15 million Americans. Lead researcher Dr. Elina Jerschow and her associates analyzed the urine of 10,348 Americans who were participants in the U.S. National Health and Nutrition Examination Survey (NHANES) of 2005-2006. Of the over 10,000 surveyed, 2,548 had detectable amounts of dichlorophenols in their urine, and 2,211 of those participants were included in the study. Out of these 2,211 people, 1,427 were found to have some form of either food or environmental allergy. Participants with higher levels of dichlorophenols are more likely to have allergies then those with low levels present in their urine. Researchers in this study argue that by consuming high levels of dichlorophenols individuals are altering the composition of bacteria in their stomachs. By over consuming dichlorophenols individuals are […]

(Beyond Pesticides, December 5, 2012) This year, December 8th marks the beginning of Hanukkah, the Jewish holiday known as the “Festival of Lights.” Hanukkah is a time for lighting the menorah, spinning the dreidel, eating good food, and spending time with loved ones””not a time for toxic chemicals to be making their way into your family’s holiday food. Latkes, or potato pancakes, served with apple sauce are the traditional food eaten on Hanukkah. But both potatoes and apples are foods that are typically high in pesticides. According to Beyond Pesticides’ Eating with a Conscience database, potatoes that are grown with toxic chemicals show low pesticide residues on the finished commodity, however, there are 78 pesticides with established tolerance for potatoes, 30 are acutely toxic creating a hazardous environment for farmworkers, 69 are linked to chronic health problems (such as cancer), 17 contaminate streams or groundwater, and 70 are poisonous to wildlife. Potatoes have been found to contain residues of the pesticides thiabendazole, endosulfan, and aldicarb ””all 3 of which are hazardous, especially to children. Similarly, there are 109 pesticides with established tolerance for apples, 38 are acutely toxic, creating a hazardous environment for farmworkers, 91 are linked to chronic health […]
