(Beyond Pesticides, July 11, 2014) In addition to previous research on the direct impacts of pesticides on pollinators and other beneficials, a recent study published by Dutch scientists establishes an additional indirect link between neonicotinoid use and insect-eating birds. The report, which came out on Wednesday, provides evidence that neonicotinoids, a class of systemic pesticides, are indirectly hurting larger creatures by reducing insect prey populations such as mosquitoes and beetles. Researchers found that in certain areas of the Netherlands where water is contaminated with high concentrations of imidacloprid, a commonly used neonicotinoid, bird populations tend to decline by an average of 3.5 percent every year. Further analysis found that this spatial pattern of decline appeared only after the introduction of imidacloprid to the Netherlands in the mid-1990s, even after correcting for land-use changes that have been known to affect bird populations in farmland. “To our surprise we did find a very strong effect on birds”, said lead author of the study, Caspar Hallmann, a Ph.D. student from Radboud University in the Netherlands, to Reuters. In fact, according to the study, which was published in the journal Nature, nine of 15 bird species studied only eat insects and all feed insects […]

(Beyond Pesticides, June 30, 2014) Decades later there are still horrifying impacts from a legacy of dumping in the environment tens of thousands of pounds of chemical waste used in the production of pesticides. The production  by the Hooker Chemical Company of C-56, the progenitor of many now banned organochlorine pesticides, has resulted in contamination and hardship. Beyond Pesticides has long advocated for the elimination of hazardous synthetic pesticides, due to unnecessary risks that put the health of both people and entire communities in jeopardy. Long after the Depression Era in Montague, MI, there were still many families who were left jobless and looking for any means to bring back a better life. The town decided to stimulate the local economy by recruiting Hooker Electrochemical Company; a chemical manufacturer originally based in New York, where it had been using an old canal bed for disposal of waste in the 1940s and was looking for a new site to build a chlor-alkali plant. Ninety-six percent of local residents signed the petition to bring them in. The situation was perfect for Hooker, which needed the vast underground reserves of salt and the lake water in the town for cooling during its industrial […]

(Beyond Pesticides, May 8, 2014) – Two citizen groups have taken the initial step toward debunking chemical-industry claims that glyphosate, the world’s most widely-used herbicide, does not bioaccumulate or metabolize in humans. The pilot study, conducted by Moms Across America and Sustainable Pulse, looked at ten breast-milk samples and 35 urine samples from across America and 21 drinking water samples. The groups commissioned Microbe Inotech Labs to conduct the analysis, and what they found raises some serious questions about the prevalence and persistence of glyphosate. In breast milk, three of the ten samples tested reveal high levels of glyphosate, meaning that the amount of glyphosate found  is between 76 ug/l to 166 ug/l. The highest glyphosate level detected in a mother is from Florida (166 ug/l) and the other two mothers with “positive” results are from Virginia (76 ug/l) and Oregon (99 ug/l). While these levels fall under the U.S. Environmental Protection Agency (EPA) drinking water maximum contaminant level (MCL) of 700 ug/l, across the pond in Europe this range of exposure is 1,000 higher than what is deemed safe. From the 35 urine samples received from across the U.S., 13 samples are above the minimum detectable level. The three […]

(Beyond Pesticides, April 28, 2014) Last week,  the  Rodale Institute, home to America’s longest-running side-by-side comparison of chemical and organic agriculture, published a white paper to support its announcement of a global campaign to generate public awareness of organic agricultural practices ability to limit the effects of climate change. The paper singles out several “regenerative organic agriculture” practices that help sequester carbon leading to less CO2 in the atmosphere. This campaign will help deliver the growing scientific literature that connects agricultural practices with climate change. The white paper,  Regenerative Organic Agriculture and Climate Change: A Down-to-Earth Solution to Global Warming, argues that it is possible to sequester more than 100% of current annual CO2 emissions by switching to widely available and inexpensive organic management practices, which are referred to in the paper as “regenerative organic agriculture.” According to the report soil sequestration can potentially sequester greenhouse gas emissions of roughly 52 gigatonnes of CO2. Even if modest assumption about soil’s carbon sequestration potential are made, regenerative agriculture can easily keep annual emissions to within the desirable lower end of the 41-47 gigatonnes of CO2, which is identified as necessary reduction to limit warming to 1.5 °C. Rodale highlights several examples […]

(Beyond Pesticides, April 15, 2014) A new study released last week by the National Park Service on contaminant use in Alaska, found traces of pesticides in fish ””pesticides which have long been banned and likely never been used within the Alaskan wilderness areas. Researchers examined three Alaskan parks renowned for their remote, pristine and protected wilderness ””Lake Clark National Park, Wrangell-St. Elias National Park and Katmai National Park”” only to find that contaminants, including PCBs at concentrations exceeding those in the lower 48 states. The study, Contaminants of Emerging Concern in Fish from Western US and Alaska National Parks””Spatial Distribution and Health Thresholds, published in the Journal of the American Water Resources Association, sought to compare contaminant level found within fish across the nation. Generally, researchers found that Alaskan fish were more likely to have traces of older chemicals, while those in the lower 48 tended to be dominated by newer chemicals. The most commonly detected chemicals are PCBs, endosulfan, sulfate and p,p’-DDE, a breakdown product of DDT.  Some of these long-banned chemicals actually exceed the U.S. Environmental Protection Agency’s (EPA) guidelines for human subsistence on fish and wildlife. Among those exceeding acceptable levels, dieldrin, chlordane, and p,p’-DDE have been […]

(Beyond Pesticides, April 2, 2014) Just last week it was announced that California ruled to remove from store shelves several rodenticide products identified by the U.S. Environmental Protection Agency (EPA) as unsafe for children and wildlife.   The maker of these products, Reckitt Benckiser, aggressive in  challenging regulators who want to restrict the company’s loose bait products,  is  suing  California to stop it from acting. The state’s new restriction on retail sales of second-generation anticoagulant rodenticides, due to take effect July 1, 2014, seeks to protect wildlife and pets from accidental poisoning from rat poisons. Reckitt Benckiser is also embroiled in challenging EPA’s decision to remove these products from the national marketplace for failure to meet federal standards. The California’ Department of Pesticide Regulation (CDPR) ruled last week that second generation anticoagulant rodenticides, including the chemicals brodifacoum, bromadiolone, difenacoum, and difethialone, found in d-CON brand products, must be classified as California-restricted materials, and only allowed to be used by certified pesticide applicators. This follows EPA’s 2013 issuance of a Notice of Intent to Cancel the registrations of rodenticide products that do not meet the agency’s new mitigation measures to reduce poisonings to children and wildlife. However, manufacturer of d-CON, Reckitt […]

(Beyond Pesticides, March 13, 2014) Part deux of a 2012 study finding that sperm counts in French men had decreased 30% over the past 16 years came to a second startling conclusion in a 2014 analysis: the cause for those dramatic decreases may be pesticides. 2012 Sperm-Count Study Published in the scientific journal Human Reproduction, the landmark 2012 study showed an alarming 30 percent decrease in sperm counts across France between 1989 and 2005. Because the data for the 2012 study were drawn from Fivnat ””a French assisted reproduction technology database”” researches made sure to limit analysis to 26,600 sperm samples from otherwise virile 35-year-old men whose partners’ fallopian tubes were either blocked or missing. This control was added to ensure that the each couple’s infertility was due to these latter problems and not a problem with the man’s sperm. Broken down, the 2012 studies identified a 1.9 percent continued annual dip in sperm concentration and also found that there was a significant 33.4% decrease in the percentage of normally formed sperm over the entire 16-year period. At the time of release, the 2012 study’s authors wrote: “To our knowledge, it is the first study concluding a severe and general […]

(Beyond Pesticides, January 31, 2014) Michael Skinner, Ph.D.,  author of the landmark study that links exposure to the insecticide DDT with multi-generational effects, ultimately contributing to obesity three generations down the line, is joining an impressive array of speakers at Beyond Pesticides’ 32nd National Pesticide Forum, April 11-12 in Portland, Oregon. Dr. Skinner’s groundbreaking research on transgenerational effects of pesticides has created quite a stir within the scientific community and backlash from the industry. A professor in the School of Biological Sciences at Washington State University, Dr. Skinner has published over 240 peer-reviewed publications and has given over 237 invited symposia, plenary lectures and university seminars. His  research focuses on the investigation of gonadal growth and differentiation, with emphasis in the area of reproductive biology. His current research has demonstrated the ability of environmental toxicants to promote the epigenetic transgenerational inheritance of disease phenotypes due to abnormal germ line epigenetic programming in gonadal development. Science Magazine has dubbed Dr. Skinner “The Epigenetics Heretic.” The article, published January 24, explores the controversy surrounding his recent findings, industry challenges to his research,  as well as the significance: “To those who don’t flatly dismiss Skinner’s findings, he has raised a tantalizing glimpse of […]

(Beyond Pesticides, January 29, 2014) People with high levels of exposure to the banned insecticide DDT are four times more likely to have Alzheimer’s disease than people with low levels, according to a new study of patients in Georgia and Texas. The research is among the first to report a connection between Alzheimer’s disease, which is the world’s most common neurodegenerative disease, and chemicals in the environment. The traces of the insecticide found in the study’s Alzheimer’s patients are comparable to the amounts found in most Americans today. Although it was banned more than 40 years ago in the U.S., DDT still persists in the environment worldwide and is still used today in developing countries for malaria abatement programs. “Our findings suggest that genetically susceptible individuals with higher levels of DDT exposure may be more at risk,” said Jason Richardson, PhD, a Rutgers University researcher who led the study. The case-control study consisting of existing samples from patients with Alzheimer’s disease and control participants from the Emory University Alzheimer’s Disease Research Center and the University of Texas Southwestern Medical School’s Alzheimer’s Disease Center measured serum levels of DDE in 79 control and 86 Alzheimer’s disease cases. Levels of DDE, a […]

(Beyond Pesticides, November 13, 2013) As the world sheds tears from reading the reports of human suffering and looks on in horror at the pictures of devastation caused by Typhoon Haiyan, the debate of whether increased occurrences of super-storms like Haiyan are just over the horizon because of man-made climate change have also taken up residence in the headlines. Coupled by coverage of the 19th session of the Conference of the Parties to the U.N. Framework Convention on Climate Change and the leak of a draft summary of the Intergovernmental Panel on Climate Change’s latest report on the impacts of global warming, the world is clearly paying attention. As the wide array of demonstrated effects and impacts of climate change are discussed on the world stage and world leaders attempt, once again, to create a meaningful plan to mitigate risks and even potentially avoid some of the most extreme threats, an important and even more deadly consequence of climate change lurks in the background: increased toxic chemical exposure. In a collection of studies and scientific reviews released earlier this year in Environmental Toxicology and Chemistry, scientists investigated a wide range of global climate change issues and toxicological impacts on the […]

(Beyond Pesticides, October 28, 2013) Scientists at Washington State University (WSU), in a laboratory study,  determined that exposure to the insecticide DDT ””banned in the U.S. since 1972, but still used today in developing countries for malaria abatement programs””impacts multiple generations, ultimately contributing to obesity three generations down the line. The study, published in the journal BMC Medicine, provides the scientific community with new information on multi-generational impacts of pesticide exposure. Lead researcher Michael Skinner, PhD., professor of biological sciences at WSU, and colleagues exposed pregnant rats to DDT to determine the long-term impacts to health across generations. The study, Ancestral dichlorodiphenyltrichloroethane (DDT) exposure promotes epigenetic transgenerational inheritance of obesity, finds that the first generation of rats’ offspring developed severe health problems, ranging from kidney disease, prostate disease, and ovary disease, to tumor development. Interestingly, by the third generation more than half of the rats have increased levels of weight gain and fat storage. In other words, the great grandchildren of the exposed rats are much more likely to be obese. “Therefore, your ancestors’ environmental exposures may influence your disease development even though you have never had a direct exposure,” the study finds. Previous studies have demonstrated that exposure to […]

(Beyond Pesticides, October, 16 2013)   Researchers at the Illinois Department of Natural Resources and the University of Illinois Urbana—Champaign have found that organochlorine pesticides and other organochlorine compounds like polychlorinated biphenyls (PBCs) are still contaminating river otters in the state, even though these chemicals have been banned for decades. Surprisingly, the levels detected are the same or higher than those detected in otters 20 years ago, highlighting the need to understand the exposure of wildlife and humans to organochlorine compounds despite their ban. In order to see what chemicals might be affecting otters, if any, the researchers examined the bodies of 23 river otters collected between 2009 and 2011. In the published study, River otters as biomonitors for organochlorine pesticides, PCBs, and PBDEs in Illinois,  scientists looked at liver concentrations of 20 organohalogenated compounds once used in agriculture and industry. The average concentrations of dieldrin, an insecticide that was used across the Midwest before being banned in 1987, actually exceeded those measured in river otters collected from 1984 to 1989. Liver concentrations of PCBs and DDE -a breakdown product of the banned DDT – were also similar to those in an earlier study showing that contamination has not decreased […]

(Beyond Pesticides, September 18, 2013) DDT, a pesticide banned in 1972, is behind the mystery surrounding the reproductive problems of dozens of endangered condors. This is according to a peer-reviewed paper written by 10 condor experts, including biologists from the Los Angeles and Santa Barbara zoos and the U.S. Fish and Wildlife Service. The researchers, who spent six years studying the reproductive problems, including eggshell thinning, in California condors have “established a strong link” to DDT in the birds’ food source. Condors are large scavenger birds with wingspans up to 10 feet and were reintroduced to California’s coast in 1997 after a century-long population decline. However, in 2006 biologists began observing thinning shells in many condor nests. Over the next six years, scientists observed condors feeding on dozens of sea lions, and found that in Big Sur, California, condor populations had low hatching success ”” just 20-40 percent. In contrast, 70-80 percent of southern California condors in the Tejon area had hatched successfully over the same time. The southern California condors are inland, and sea lions are not a food source. According to the study published in the journal, The Condor, the outer crystalline layer of shells was absent or […]

(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 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, June 28, 2013) The United States Environmental Protection Agency (EPA) is poised to raise the allowable limits of the herbicide glyphosate (Roundup) in certain food commodities like carrots, sweet potato, and mustard seeds. Some of the allowable limits, or tolerances, will more than double! Increasing the levels of Roundup on food will pave the way for an overall increase in the use of this chemical in agriculture. The problem is Roundup is toxic to human and environmental health. In fact, a recent MIT study finds that glyphosate’s interference with important enzymes in the body can lead to gastrointestinal disorders, obesity, diabetes, heart disease, autism, infertility, cancer and Alzheimer’s disease. Drinking water contaminated with Roundup can lead to congestion of the lungs and increased breathing rate, as well as kidney damage and reproductive effects. Given that alternative methods of growing food and managing weeds are available, like those that exist in organic agriculture, it is unreasonable for EPA to increase human exposures to Roundup. Tell EPA No More Roundup In Our Diet by July 1st! To have the most impact, EPA needs to hear directly from you with your comment in the docket! You may use the sample text […]

(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, 23, 2013) A report released by the Surface Water Ambient Montioring Program (SWAP) has found in California that “detection of pyrethroid pesticides in sediment increased from 55 percent of the statewide samples in 2008 to 85 percent in 2010.” The findings are among the results of the Stream Pollution Treads, or SPoT, monitoring program, an annual assessment of pollution in streams in California. The report also found that stream beds in urban areas have higher levels of pyrethroids that those in agricultural areas. The SWAP report summarizes results of the 2009 and 2010 annual surveys and compares those results to the 2008 SPoT data. Beyond the 30 percent increase of pyerthriods detected in sediment, the percentage of highly toxic samples increased from 6 percent to 67 percent when toxicity tests were conducted at a colder temperature that more closely matched the normal surface water temperature in average watersheds. These results, according to the report, “suggest that current monitoring may underestimate the occurrence of parathyroid-associated toxicity using the standard protocol.”   The report also acknowledges that some pyrethroids, such as bifenthrin, may persist longer than others, and the chronic impacts of these pesticides may be underestimated by some […]

(Beyond Pesticides, April 3, 2013)   Last week, Syngenta and Bayer CropScience proposed an action plan to forestall pending European Union (EU) restrictions on their neonicotinoid products that have been linked to global bee declines.   Stating that a ban on their products would not save hives, the plan focuses on implementing agricultural best management practices, planting habitat, and new research and development, all of which fail to seriously address the real problem that their products are highly toxic to bees. This new industry plan comes on the heels of the European Union (EU) stalemate on bee health, and after the EU food safety agency concluded that certain neonicotinoids pose unacceptable risks to bees. Public and regulatory scrutiny is now focused on the class of chemicals — neonicotinoids— linked to bee health decline. Neonicotinoids have been shown by numerous studies to adversely impact the health of  bees, as well as  birds and aquatic organisms. Beyond Pesticides, Center for Food Safety, and Pesticide Action Network North America joined beekeepers and other environmental and public health advocacy groups to sue the U.S. Environmental Protection Agency (EPA), calling for the suspension of the neonicotinoids, clothianidin and thiamethoxam. The science continues to document these […]

(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 […]

(Beyond Pesticides, February 15, 2013) Bats around the U.S. are being decimated by White Nose Syndrome (WNS). The deadly disease was detected recently at Kentucky’s Cumberland Gap National Historic Park, according to the National Park Service. Based on laboratory testing, three bats were discovered with WNS, coming from three separate caves in the park. The cold-loving fungus thrives on hibernating bats, spreading in 2006 from a cave in New York State to 21 other states in the East and Midwest. In 19 of these states there have been confirmed cases of WNS, not including detections in four Canadian Provinces (see map).  White nose syndrome is usually transmitted bat-to-bat, although the spore can also spread through human clothing, shoes or gear. The fungus causing WNS, Geomyces destructan, is extremely lethal to hibernating bats–though posing no health threats to humans, pets, or other animals– killing 90% of bats where the fungus had persisted for a year or more, totaling 5.8 million bat deaths since 2006. There are six species of cave-dwelling bats that are susceptible to WNS, including the endangered Indiana bat. There are also three species of tree-dwelling bats in the parks, but these are less at risk for contamination as […]
