(Beyond Pesticides, September 1, 2015) A  research study published in the journal Environmental Health  links chronic, ultra-low dose exposure to glyphosate in drinking water to adverse impacts on the health of liver and kidneys. The study, Transcriptome profile analysis reflects rat liver and kidney damage following chronic ultra-low dose Roundup exposure, is the latest in a string of data showing unacceptable risks resulting from exposure to glyphosate and products formulated with the chemical, like Monsanto’s Roundup. Researchers conducted the study by exposing rats to minute (0.1 parts per billion) doses of Roundup in drinking water for a period of 2 years. After noting tissue damage and biochemical changes in the blood and urine of exposed animals that was indicative of organ damage, the authors attempted to confirm their findings by analyzing changes in gene expression within liver and kidneys. Of 4,447 gene transcript clusters analyzed by scientists, 4,224 showed some alteration. Compared to non-exposed rats, “[t]here were more than 4,000 genes in the liver and kidneys whose levels of expression had changed,” said Michael Antoniou, PhD, senior author of the study to Environmental Health News. Authors indicate that the changes in gene expression observed in the study are associated with […]

(Beyond Pesticides, August 31, 2015) A study published in Environmental Science and Technology, funded in part by the U.S. Geological Survey (USGS), has found that almost 2 million people are living near aquifer sites contaminated with uranium that is mobilized by human-contributed nitrate. Nitrate is a common groundwater contaminant that is sourced mainly from chemical fertilizers and animal waste. Chronic exposure to elevated levels of uranium can lead to kidney damage and cancer. These findings emphasize the dangers of synthetic fertilizer overuse, and highlight the need to switch to safer alternatives. The study, “Natural Uranium Contamination in Major U.S. Aquifers Linked to Nitrate,” analyzed approximately 275,000 groundwater samples from the Great Plains regions and California, finding that many residents often live less than a mile from uranium-contaminated wells that exceed guidelines set by the Environmental Protection Agency (EPA). In the High Plains aquifer, researchers find uranium concentrations up to 89 times EPA standards, while the Central Valley aquifer measure up to 180 times EPA standards. The study also reports that 78% of these uranium-contaminated sites are linked with the presence of nitrates. Nitrate mobilizes naturally occurring uranium through a series of reactions that oxidize the material, making it water soluble. […]

(Beyond Pesticides, August 24, 2015) At the start of the  school year, it is critical to check in with school administrators to make sure that students and teachers will not be exposed to hazardous pesticides used in the school’s buildings or on playing fields. Whether a parent, teacher, student, school administrator, landscaper or community advocate, there are steps that  can taken to make sure the school environment is a safe from  toxic chemicals, as the new  school year begins. For Parents and Teachers: Because children face unique hazards from pesticide exposure due to their small size and developing organ systems, using toxic chemicals to get rid of insects, germs, and weeds can harm students much more than it helps. Studies show children’s developing organs create “early windows of great vulnerability” during which exposure to pesticides can cause great damage. This is supported by the  findings of the American Academy of Pediatrics (AAP) which concluded that, “Children encounter pesticides daily and have unique susceptibilities to their potential toxicity.”  The report also discusses how children  are exposed to pesticides every day in air, food, dust, and soil. Children also frequently come into contact with pesticide residue on pets and after lawn, garden, […]

(Beyond Pesticides, August 19, 2015) Local fogging for  mosquito control turned tragic for a Palo Alto, California beekeeper who lost hundreds of honey bees from his backyard hives. The beekeeper, who also produces organic honey, now fears his honey is contaminated. The fogging, which occurred last month, was in response to positive tests for West Nile virus in mosquito samples. Many mosquito control pesticides are toxic to honey bees and given the declining populations of pollinators, vector control officials are being asked to carefully consider the risks associated with pesticide spraying. According to the local NBC affiliate, beekeeper Rondolph Tsien believes he was not given sufficient time to protect his bees from the mosquito fogging and, despite trying to cover his hives with a tarp to protect his bees from drifting pesticides, many were lost. A mosquito sample tested positive for West Nile virus about one mile from Mr. Tsien’s home, putting his property in the catchment area for fogging. Mr. Tsien worries the surviving bees will produce contaminated honey that can no longer be labeled organic. A Santa Clara County Vector Control representative stated during an interview that the county uses  an “extremely low dose” of pesticides during fogging […]

(Beyond Pesticides, August 7, 2015) Parental exposure to environmental stressors, such as pesticides, before a child is conceived can alter the way genes are expressed in the mother and father, ultimately harming the child’s health when those genes are passed down to the next generation, according to an article published in the Endocrine Society’s journal Endocrinology. “In regard to environmental stressors, a good start lasts a lifetime,” said Philippe Grandjean, M.D., Ph.D. Dr. Grandjean is Professor of Environmental Medicine at the University of Southern Denmark and Adjunct Professor of Environmental Health at the Harvard University’s T.H. Chan School of Public Health and an author of the article. “Unfortunately, current testing paradigms do not properly assess the impact of risk factors during vulnerable exposure windows. Without new policies and guidelines, we cannot have a universal healthy start for children.” The article, titled Life-Long Implications of Developmental Exposure to Environmental Stressors: New Perspectives, summarizes the newest science and key insights from the 4th  Conference on Prenatal Programming and Toxicity (PPTOX IV). More than 300 people attended the event in Boston, MA in October 2014. The meeting featured poster presentations discussing the impact of chemical, physical, and biological environmental stressors on the interconnected […]

(Beyond Pesticides, August 5, 2015) The United Kingdom (UK) is poised to harvest higher than expected yields of winter oilseed rape (canola) in its first neonicotinoid-free growing season since the European moratorium on neonicotinoids went into place in 2013. This bumper harvest comes amid the recent approval of an emergency exemption for neonicotinoid use on the crop in certain areas of the UK, and disproves the industry argument  that  the crop would falter without the use of neonicotinoids. Activists argue that these findings show there is ”˜no emergency’ for neonicotinoid use and that the current moratorium should remain in effect. The first harvest results of winter oilseed rape (canola) planted without neonicotinoid seed treatments have come in – and farmers are experiencing a better than usual crop. Figures for the first oilseed rape harvest since the European-wide ban on neonicotinoid pesticides was introduced show that the yield so far is higher than the average for the previous decade, when the chemicals were used on the majority of oilseed rape grown in the UK. Farmers Weekly, a leading multimedia information service for farmers and agricultural businesses, has reported that yields are up by as much as eight percent. The European Union […]

(Beyond Pesticides, August 4, 2015) Nearly every food available for purchase at the U.S. Congressional Dining Hall contains detectable levels of neonicotinoids (neonics), chemical insecticides implicated in the global decline of wild and managed pollinators. The results of a new study, performed by the American Bird Conservancy (ABC) and the Harvard T.H. Chan School of Public Health, reveals how reliance on these toxic chemicals can both directly and indirectly affect  our food supply. Authors of the study hope the results will build Congressional support for the Saving America’s Pollinators Act of 2015, which would suspend the use of neonics while an independent review analyzes the chemical’s effects to birds, pollinators, and other wildlife. Researchers for the study conducted two rounds of food testing, the first in January, and the second in May 2015. Approximately half of samples were taken from the House Longworth Cafeteria and half from Senate Dirksen Cafeteria in Washington, D.C. In total, 66 food samples were tested for the presence of neonicotinoids. Of that, 60, or 91% of samples tested positive for one neonic, and 47, or 71% of samples had two or more neonics present. “We were surprised to find that most foods contained multiple neonicotinoids, […]

(Beyond Pesticides, July 31, 2015) New information has surfaced regarding the role of agrochemical giants Bayer and Syngenta in the United Kingdom (UK)’s recent decision to temporarily allow the use of neonicotinoid seed treatment on oilseed rape crop. A record of the meeting, involving the UK government’s expert committee on pesticides (ECP) and industry representatives, had previously been suppressed. The newly released record of the meeting shows that Bayer and Syngenta were the only external representatives asked to answer the ECP’s questions. The emergency use, which has been granted for 120 days, allows growers to use Bayer’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals known as neonicotinoids  (neonics), which have been  linked  to pollinator decline. These pesticides are associated with  decreased learning,  foraging  and navigational ability in bees, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. Used widely in agriculture as seed treatment for various crops, foraging bees, in the absence of their native habitat, are exposed to fields of poison where even pollen and nectar are contaminated. In addition to toxicity to bees, neonicotinoids have been shown […]

(Beyond Pesticides, July 22, 2015) Months after the World Health Organization (WHO) formally associated the world’s most widely used herbicide  -glyphosate (Roundup)- with cancer, one of the world’s leading experts on cancer risk, and co-author of the WHO’s report, Christopher Portier, PhD, told a scientific briefing in London that the herbicide can damage human DNA, which could result in increased cancer risks. This finding comes on the heels of a call by the Soil Association for a United Kingdom (UK) ban on the use of glyphosate after finding residues of the chemical in bread. Earlier this spring, the WHO’s International Agency for Research on Cancer (IARC) classified glyphosate as Group 2a “probable” human carcinogen based on sufficient evidence of carcinogenicity in laboratory animals. Since then industry has hit back defending its champion product, even attempting to undercut the WHO’s findings with an industry-based  assessment that reached the opposite conclusion, based on classified industry reports.  Now an internationally recognized scientist, Dr.  Portier, former associate director, National Institute of Environmental Health Sciences, (NIEHS) and director of the Office of Risk Assessment Research at NIEHS, reiterated WHO’s findings at the UK Soil Association scientific briefing in Westminster on July 15. During his presentation, […]

(Beyond Pesticides, July 13, 2015) Many factors have been identified in bee and other pollinator decline across the globe, including loss of habitat, disease, and pesticides. A  new study from researchers in North American and Europe finds that the  changing climate also plays a vital role in decreasing bee habitat and thus reducing populations. The study reports that North American and European bumble bees are unable to colonize new warmer habitats north of their historic range, while simultaneously disappearing from the southern portions of their range. Published in Science, the study,  Climate change impacts on bumblebees converge across continents,  which is a comprehensive look at 67 bumblebee species and their territories over the last century, finds that many North American and European bumblebees have retreated from the southern edge of their historic ranges (away from the equator). While other species of animals have been able to adapt to climate change by expanding their habitats, bumblebees have not shifted to warming northern climes and are experiencing shrinking distributions in the southern ends of their range. The rusty patched bumblebee (Bombus affinis), for instance, has disappeared from parts of the southeastern U.S. Bumblebees are also retreating to higher elevations, shifting upward by […]

(Beyond Pesticides, July 9, 2015) Last week, a federal judge ruled that a voter-passed ban on the cultivation of genetically engineered (GE) crops in Maui is preempted by federal and state law, and is invalid. According to the SHAKA Movement legal counsel, the decision, at least temporarily, invalidates a local ordinance that sought to protect against serious harms caused by these practices, and ignores the harms to Maui county and the Hawaii Constitutional mandate placing obligations and duties on the counties to protect the natural environment. In addition to the SHAKA Movement, Center for Food Safety and Earthjustice have pledged to appeal the decision. “The District Court’s ruling is a big blow to Maui County voters that adopted this ordinance, given the dangers involved with GMO operations,” said  SHAKA spokesperson Mark Sheehan, PhD, who was also one of the five citizens who sponsored the ballot initiative. “We do intend to appeal this decision and are hopeful that the 9th Circuit will recognize the impact that today’s ruling has on the community.” In November 2014, Maui residents passed a ballot initiative prohibiting the growth, testing or cultivation of GE crops in Maui County until an environmental and public health study can […]

(Beyond Pesticides, June 29, 2015) A recent study has provided supporting evidence to previous work showing that sublethal doses of imidicloprid, a toxic neonicotinoid insecticide, impairs olfactory learning in exposed honey bee workers. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have experienced ongoing and rapid population declines. The science has become increasingly clear that pesticides (especially the neonicotinoid class of insecticides), either acting individually or synergistically, play a critical role in the ongoing decline of honey bees and wild pollinators. Neonicotinoids can be persistent in the environment, and have the ability to translocate into the pollen and nectar of treated plants. “Honeybees need to learn to associate nectar reward with floral odor. One of the main reasons why flowers produce odor is so that this odor can be learned by pollinators and used to repeatedly visit the same flower species. Without this repeat visitation, pollination does not occur. We showed that a neonicotinoid pesticide, at sublethal doses, harms this odor memory formation,”  Chinese Academy of Science’s Ken Tan, who led the study, told CBS News in an email interview. Published in Nature on June 18, 2015, the study finds that “adults that ingested […]

(Beyond Pesticides, June 19, 2015) A new study directly links exposure to dichlorodiphenyltrichloroethane (DDT) in utero to the development of breast cancer later in life. Published in the Journal of Clinical Endocrinology and Metabolism, the study looked at data that were taken from a California program that  evaluated  samples from women during 1960s, when DDT use was popular. DDT is known to be an endocrine disruptor, and is linked to serious health effects. Although DDT has been banned for many years, residues still linger in certain areas of the U.S. and continue to cause environmental and health hazards. The recent study, titled DDT Exposure in Utero and Breast Cancer,  focuses on 118 mothers who were members of Kaiser Foundation Health Plan from 1959-1967 and had daughters that were diagnosed with breast cancer by their 50s. Stored blood samples from these mothers gave researchers an idea of how much DDT they were exposed to during pregnancy or soon after giving birth. They found that elevated levels of DDT in the mother’s blood led to a four-fold increase in the daughter’s risk of developing breast cancer. Among those with cancer, 83% had a form of cancer called estrogen positive breast cancer, which […]

(Beyond Pesticides, June 9, 2015) Agricultural pesticides are sprayed intensively throughout the growing season in New York’s conventional apple orchards. Researchers at Cornell University found that as the use of pesticides on these farms increased, the abundance of wild bees declined significantly. The study, published in the Proceedings of the Royal Society B, focuses on the effects of conventional pesticide use on wild bees, which have often been overlooked in the midst of an ongoing crisis with managed honey bee colonies. “Because production of our most nutritious foods, including many fruits, vegetables and even oils, rely on animal pollination, there is an intimate tie between pollinator and human well-being,” said Mia Park, an assistant professor at the University of North Dakota and the paper’s first author, who worked on the study as a Cornell entomology PhD graduate student. Ms. Park and her colleagues analyzed wild bee populations on 19 apples orchards across the state of New York between 2011 and 2012. Data was broken down by class of pesticide (fungicide, insecticide, herbicides), and timing of applications (before, during, and after flower bloom). Researchers also analyzed the percentage of natural areas within the surrounding landscape. The study uncovered a number of […]

(Beyond Pesticides, May 12, 2015) Last week Kaua’i County Councilmember Gary Hooser returned from agrichemical giant Syngenta’s shareholder meeting in Basel, Switzerland, where he addressed the company and its stakeholders on  the corporation’s lawsuit against the  small Hawaiian island of Kaua’i. The Councilmember indicates that, although the company is unlikely to meet his request to drop its lawsuit against Ordinance 960, which generally creates buffer zones prohibiting pesticide use around schools, hospitals, and parks, the trip overall was a success. “Our main purpose was one of education and information, to tell our story in the home city of Syngenta, and we were greeted with open arms and really managed to get the word out,” Mr. Hooser said to The Garden Isle on Monday. VIDEO: See Councilmember Hooser’s speech to Syngenta: Part 1 | Part 2 (Note: Credit and thanks to Kauai activist Fern Rosenstiel for filming this video despite attempts by Syngenta to suppress her ability to do so.) In a related matter, it  was announced earlier this week that  a federal court awarded over $500,000 to 15 Kaua’i residents who launched a  lawsuit (separate from the one above) against another agrichemical company on the island, DuPont Pioneer. Residents won […]

(Beyond Pesticides, May 7, 2015) The Pennsylvania Fish and Boat Commission (PFBC) has confirmed that a rare malignant tumor was found on a smallmouth bass caught in the Susquehanna River by an angler late last summer. The finding was confirmed by two independent laboratory tests, including the U.S. Fish and Wildlife Service (FWS) and the Aquatic Animal Health Laboratory at Michigan State University.  Although it only represents one individual fish from the overall population, it provides additional evidence —which includes the prevalence of intersex fish discovered last summer”” that the health of the fish community residing in the river is being compromised, according to PFBC executive director John Arway. Though the findings do not point to a specific cause for the cancer found on the smallmouth bass (SMB), agricultural pesticides, particularly endocrine disrupting chemicals, that have been found in the watershed, likely play a part in the rampant disease issues in SMB in the Susquehanna River. “As we continue to study the river, we find young-of-year and now adult bass with sores, lesions and more recently a cancerous tumor, all of which continue to negatively impact population levels and recreational fishing,” Mr. Arway said. “The weight-of-evidence continues to build a […]

(Beyond Pesticides, April 29, 2015) Much to the dismay of activists and concerned local residents, the Washington Department of Ecology (Ecology) approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens valuable shellfish (oyster) beds in Willapa Bay and Grays Harbor in Washington state. Imidacloprid is known to be toxic to bees but is also toxic to aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. The shellfish industry is important to the Pacific Northwest, injecting an estimated $270 million or more into the region’s economy, and providing jobs for many. Washington’s tidelands, especially those in Willapa Bay, have been particularly productive for more than 100 years. However, according to shellfish growers, the burrowing shrimp (ghost shrimp, Neotrypaea californiensis,  and mud shrimp, Upogebia pugettensis) undermines the industry. The creatures burrow into shellfish beds, making the beds too soft for shellfish cultivation. Their burrowing churns the tidelands into a sticky muck, smothering the oysters. After several years of deliberations and studies, Ecology identified imidacloprid as its  preferred choice for eradicating the shrimp. According to the agency, imidacloprid disrupts the burrowing shrimps’ […]

(Beyond Pesticides, April 24, 2015) Two new studies reporting on the adverse effects of neonicotinoids on bees were published Wednesday in the journal Nature, adding to a growing body of scientific literature linking the controversial class of pesticides to the global decline in bee populations. The conclusions reached by the two studies find that not only does neonicotinoid exposure result in reduced bee density, nesting, colony growth, and reproduction, but also that bees in fact prefer foods containing neonicotinoid pesticides despite their adverse effects. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. In one study, “Seed coating with a neonicotinoid insecticide negatively affects wild bees,” Swedish scientists report that wild bees […]

(Beyond Pesticides, April 1, 2015) According to a new study from Harvard University researchers, eating fruit and vegetables containing pesticide residues adversely affect men’s fertility, leading to fewer and poorer quality sperm. The study, published online in the journal,  Human Reproduction, adds to a growing body of research that finds pesticide exposures give rise to impaired reproductive function, including reduced sperm counts, sperm quality and reduced fertility in exposed men. The results of this study also underscore the importance of an organic diet in reducing pesticide exposures. The study, “Fruit and vegetable intake and their pesticide residues in relation to semen quality among men from a fertility clinic,” believed to be the first to  look into the consumption of fruits and vegetables with high levels of pesticide residue in relation to semen quality, and conducted by researchers at Harvard University’s TH Chan School of Public Health, found that men who ate the greatest amount of fruit and vegetables with high levels of pesticide residue had a 49% lower sperm count and a 32% fewer normally formed sperm than those who consumed the least. Jorge Chavarro, MD, assistant professor of nutrition and epidemiology and co-author of the study, said, “We found […]

(Beyond Pesticides, March 13, 2015) Exposure to endocrine (hormone) disrupting chemicals (EDC) results in approximately € 150 billion ($162 billion) in health care costs in the European Union each year, according to panels of scientists tasked by the EU Commission to study their impact. “The shocking thing is that the major component of that cost is related to the loss of brain function in the next generation,” Philippe Grandjean, M.D. of Harvard University, one of the report’s authors, told the Guardian. EDCs, contained in common household products such as detergents, disinfectants, furniture, plastics, and pesticides, interfere with the body’s hormone system either by mimicking naturally produced hormones, blocking hormone receptors in cells, or effecting the transport, synthesis, metabolism or excretion of hormones. These impacts can result in devastating effects on one’s health, including behavioral and learning disorders, such as Attention Deficit Hyperactivity Disorder (ADHD), birth defects, obesity, early puberty, infertility, cardiovascular disease, and childhood and adult cancers. Nearly 100 percent of people have detectable amounts of EDCs in their bodies, according to the introductory guide to EDCs published by the Endocrine Society and IPEN. “Our brains need particular hormones to develop normally —the thyroid hormone and sex hormones like testosterone […]

(Beyond Pesticides, March 12, 2015) Marijuana may be legal in your state for medicinal and recreational use, but are toxic pesticides used in its production? A study released today of the 23 states and the District of Columbia that have legalized marijuana finds a patchwork of state laws and evolving policy that define allowed pesticide use and management practices in cannabis production. This variety of state law is occurring in the absence of federal registration of pesticide use for cannabis production because of its classification as a narcotic under federal law. The investigation, Pesticide Use in Marijuana Production: Safety Issues and Sustainable Options, evaluates the state laws governing pesticide use in cannabis production where it is legalized. “The use of pesticides in the cultivation of cannabis has health implications for those growing the crop, and for users who are exposed to toxic residues through inhalation, ingestion, and absorption through the skin,” said Jay Feldman, executive director of Beyond Pesticides. “The good news is that five states and DC have adopted rules that require marijuana to be grown with practices that prevent the use of pesticides. State officials have an opportunity to restrict all pesticide use at the front end of […]

(Beyond Pesticides, March 4, 2015) The 9th U.S. Circuit Court of Appeals has agreed to hear the case brought by beekeepers challenging the U.S. Environmental Protection Agency’s (EPA) approval of a toxic pesticide known to be toxic to bees. In 2013, the beekeepers filed suit against the agency, citing that the new chemical, sulfoxaflor, as further endangering bees and beekeeping and noting that their concerns were not properly addressed by EPA before registration was granted. Sulfoxaflor is a sub-class of the neonicotinoid pesticides that have been linked to global bee declines. The Court has agreed to hear the case on April 14, 2015. The case, Pollinator Stewardship Council v. EPA, which requests changes to EPA’s product label for sulfoxaflor, was first filed July 2013. The petitioners include the Pollinator Stewardship Council, the American Honey Producers Association, the National Honey Bee Advisory Board, the American Beekeeping Federation, and beekeepers Bret Adee, Jeff Anderson and Thomas Smith. The beekeeper groups are represented by Earthjustice. The case is one of a number of pending legal cases on EPA’s pesticide decisions under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), including one submitted March 2013 by Beyond Pesticides, the Center for Food Safety, beekeepers, […]

(Beyond Pesticides, February 27, 2015) New research from the University of Minnesota presents some of the first evidence linking the bee-killing insecticides known as neonicotinoids to monarch butterfly deaths. The study finds that milkweed plants, which monarch butterflies need to survive, may also retain neonicotinoids from nearby plants, making milkweed toxic to monarchs. Monarch population numbers have fallen by 90% in less than 20 years. This year’s population was the second lowest since careful surveys began two decades ago. The critical driver of monarch decline  is the loss of larval host plants in their main breeding habitat, the midwestern Corn Belt. Monarchs lay eggs exclusively on plants in the milkweed family, the only food their larvae will eat. University of Minnesota entomologist Vera Krischik, Ph.D. fed butterflies milkweed plants treated with the neonicotinoid insecticide known as imidacloprid in amounts that might typically be found on backyard plants. While adult monarchs and painted lady butterflies were not affected, which, according to Dr. Krischik, indicates the ability of the adults to detoxify, the larvae of both species of butterflies died. During the course of the study, larvae fed on the treated plants for seven days. “For the monarch, nobody was left that […]
