(Beyond Pesticides, November 12, 2013) On November 6 BASF, a German agrochemical company, took legal action in the General Court of the European Union (EU) to challenge the EU Commission’s decision to restrict seed treatment uses of the insecticide fipronil. BASF joins chemical companies Bayer and Syngenta in challenging the EU’s decision to restrict the use of certain pesticides that are harmful to pollinators. The EU Commission’s decision to restrict the use of fipronil in July came after the Commission’s landmark decision announcing a two-year continent-wide ban  on the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam. The pesticides have been linked to the decline in bee populations.  Twenty-three European Union Member States supported the fipronil restriction, two Member States voted against, and three Member States abstained during the standing committee vote. BASF argued that its  legal action against the EU is based on a disproportionate application of the precautionary principle. However, overwhelming scientific evidence supports the position that fipronil is highly toxic to bees. Fipronil, a phenyl pyrazole broad-spectrum insecticide, was first introduced in the U.S. in 1996 for commercial turf and indoor pest control and is highly toxic to bees. A recent investigation reveals that fipronil is responsible for the […]

(Beyond Pesticides, November 7, 2013) A study released this week established a strong connection between endometriosis and exposure to two dangerous pesticides: lindane and mirex. While the results are not surprising given past connections between these pesticides and their endocrine-disrupting effects, this new study, Organochlorine Pesticides and Risk of Endometriosis: Findings from a Population-Based Case-Control Study, is one of the first to examine the association between organochlorine pesticides (OCPs) and endometriosis, one of the most common gynecological diseases, in women in the general population. The study’s authors, Kristen Upson, Ph.D. et al,  explained to Environmental Health Perspectives, “Our study suggests that exposure from extensive past use of environmentally persistent OCPs in the United States, or present use in other countries may impact the health of the current generation of reproductive-age women with regard to a hormonally-mediated disease.” In conducting the study, researchers selected a group of women with surgically-confirmed cases of endometriosis from the greater Pacific Northwest area. This group of women was then divided into four groups, based on the level of pesticide in each woman’s blood. Women in the second-highest exposure group for beta-hexacyclochlorohexane (beta-HCH), a byproduct of lindane, had a 70 percent greater risk of endometriosis than […]

(Beyond Pesticides, November 6, 2013) A federal district court approved a settlement Monday requiring the U.S. Fish and Wildlife Service to better protect California red-legged frogs from seven common pesticides known to be highly toxic to amphibians. The settlement gives the agency two years to prepare “biological opinions” under the Endangered Species Act (ESA) to analyze pesticide use in and near the frog’s aquatic and upland habitats.   A 2006 legal settlement secured by the Center for Biological Diversity (CBD) required the U.S. Environmental Protection Agency (EPA) to assess pesticide impacts on red-legged frogs and to then formally consult with the Fish and Wildlife Service (FWS) under the ESA. The EPA’s assessments found that widespread use of pesticides is likely harming red-legged frogs and the court ordered temporary pesticide use restrictions that remain in effect today. EPA determined that 64 other pesticides are “likely to adversely affect” or “may affect” red-legged frogs. Despite the EPA’s findings, however, FWS and EPA failed to complete the required consultation, resulting in the litigation by CBD that culminated in Monday’s settlement. The court order gives FWS two years to complete biological opinions for seven pesticides: glyphosate, malathion, simazine, pendimethalin, permethrin, methomyl and myclobutanil. This […]

(Beyond Pesticides, November 1, 2013) Insecticides commonly used in homes and schools are associated with behavioral problems in children, according to a recent study by Canadian researchers. The study investigates exposure to pyrethroid pesticides, used in more than 3,500 products, including flea and tick controls, cockroach sprays, and head lice controls. The study, Urinary metabolites of organophosphates and pyrethroid pesticides and behavioral problems in Canadian children, published in the journal Environmental Health Perspectives, raises serious concerns about the impact of pyrethroids, which are increasingly used as a replacement for organophosphates. This study uses data from the Canadian Health Measures Survey (2007-2009), a nationally representative survey, so researchers are able to apply these findings to the entire population of Canadian children. In a previous study among U.S. children, researchers at the National Health and Nutrition Examination Survey (NHANES) examined the metabolites of pyrethroids in children below the age of six. Similarly, they found pyrethroid insecticides in more than 70 percent of the samples, concluding that children had significantly higher metabolite concentrations than those of adolescents. Together these studies demonstrate that exposure is widespread, with real impacts to human health. In the recent study, researchers analyzed organophosphate and pyrethroid metabolites in the […]

(Beyond Pesticides, October 31, 2013) Bats get a bad rap on Halloween with their image synonymous with blood-sucking vampires; however, the real scary thing about bats is that they are disappearing due to a myriad of threats, including pesticides, habitat destruction, and the horrible white-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus (Geomyces) destructans. Researchers are reporting an even bleaker picture, finding very little evidence of what might stop the disease from spreading further and persisting indefinitely in bat caves. The new study, from researchers at the Illinois Natural History Survey at the University of Illinois, found that the fungus can make a meal out of just about any carbon source likely to be found in caves, said graduate student Daniel Raudabaugh, who led the research under the direction of survey mycologist Andrew Miller, Ph.D. The study, Nutritional Capability of and Substrate Suitability for Pseudogymnoascus destructans, the Causal Agent of Bat White-Nose Syndrome is published in PLOS One. “It can basically live on any complex carbon source, which encompasses insects, undigested insect parts in guano, wood, dead fungi and cave fish,” Mr. Raudabaugh said. “We looked at all the different nitrogen sources and found that basically it can […]

(Beyond Pesticides, October 29, 2013) Early-life exposure to the herbicide atrazine makes frogs more susceptible to death from chytrid (Batrachochytrium dendrobatidis), a fungal disease implicated in amphibian declines across the globe. The research, Early-life exposure to a herbicide has enduring effects on pathogen-induced mortality, published in the Proceedings of the Royal Society B and led by University of South Florida (USF) biologist Jason Rohr, Ph.D, provides critical information for scientists hoping to stem the global demise of amphibian populations. “Understanding how stressors cause enduring health effects is important because these stressors might then be avoided or mitigated during formative developmental stages to prevent lasting increases in disease susceptibility,” Dr. Rohr explains. Researchers exposed tadpoles to atrazine at levels found in the environment for a period of  six days during the animal’s development, in combination with exposure to chytrid fungus (linked to worldwide amphibian decline), resulted in increased mortality 46 days later. According to the study, “[E]arly-life exposure to atrazine altered growth and development, which resulted in exposure to chytrid at more susceptible developmental stages and sizes, and reduced tolerance of infection, elevating mortality risk at an equivalent fungal burden to frogs unexposed to atrazine. Moreover, there was no evidence of […]

(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 24, 2013) A team of scientists in Italy believe they have found the molecular mechanism through which neonicotinoid pesticides adversely impacts the immune system of honey bees. The team’s experiments suggest that exposure to neonicotinoids results in increased levels of a particular protein in bees that inhibits a key molecule involved in the immune response, making the insects more susceptible to attack by harmful viruses. Though previous studies have indicated that exposure to minute amount of neurotoxic pesticides like neonicotinoids severely impair the immune systems of bees, making them more susceptible to pathogens, the underlying mechanism has was not yet been fully  understood. The study, Neonicotinoid clothianidin adversely affects insect immunity and promotes replication of a viral pathogen in honey bees, is published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). This work is the latest of several studies to add weight to the urgency of repeated calls from U.S. beekeeper and environmental groups for the Environmental Protection Agency (EPA) to  suspend the use of neonicotinoid pesticides, as the European Commission recently decided this past April. Neonicotinoids, a class of insecticides that includes clothianidin and imidicloprid, are taken up […]

(Beyond Pesticides, October 23, 2013) Ball State University, Indiana has cancelled plans to spray herbicides on the lawns around its K-12 school after objections from parents worried that it would expose their children to toxic chemicals. The university planned to use Trimec 992, a 2,4-D product, but a petition started by parents helped to put a stop to the weedkiller. The spraying was scheduled for last week, the start of the fall break at Burris Laboratory School, a separate K-12 school district overseen by Ball State University. School Principal Cathlene Darragh sent an email to Burris parents last Friday  explaining that  the school decided against the spraying. “We have received a great deal of feedback from parents and the community about possible weed and pest control for the school lawn that was scheduled for this weekend. We have worked with the facilities department to further evaluate the need to spray. Upon further consideration, we have decided to forgo the scheduled spraying.” Parents mobilized after it became known that the school planned to spray Trimec 992, a 2,4-D product on school grounds. 2,4-D, a widely used herbicide in many ‘weed and feed’ lawn care products, is associated with many human and […]

(Beyond Pesticides, October 22, 2013) Nearly a week after plant geneticists from the world’s largest agrichemical companies accepted the World Food Prize, an Associated Press (AP) investigation links the effect of their work to soaring pesticide use and resulting health problems.  According to the  AP, the advent of “no-till” farming methods in Argentina with the use of genetically engineered (GE) crops and companion pesticides has caused significant health impacts in farming towns abutting GE fields. Since the introduction of these practices in Argentina by agrichemical companies such as Monsanto, cancer rates have skyrocketed and the number of birth defects has quadrupled. Argentina was an early adopter of GE technology in 1996, when it was billed as the silver bullet to solve world hunger with increased crop  productivity, and improved human and environmental health resulting from decreased pesticide use. The most widely used GE crops, such as Monsanto’s Roundup Ready line of corn and soybeans, allow farmers to apply the herbicide glyphosate during and after seed plantings in order to kill weeds without risk of the main crop dying off. Today, almost all the corn, soy, and cotton produced in the country are GE. As the  AP reports, and researchers in […]

(Beyond Pesticides, October 21, 2013) A study conducted by Sussex University researchers has identified the garden plants most attractive to  pollinating insects. The study’s findings are important as pollinating insects are declining globally and are facing growing habitat losses. The study also gives vital scientific information to individuals and communities on plants that are most beneficial to pollinators. Although creating pollinator friendly habits is an important step to slowing pollinator population decline, environmental groups and activists are focused on addressing the underlying problem that leads to pollinator population loss: the continuous use of toxic pesticides. The study, Quantifying variation among garden plants in attractiveness to bees and other flower-visiting insects, published in Functional Ecology,  collected data over two summers by counting flower-visiting pollinators on 32 popular garden plant varieties to determine which varieties are more attractive to pollinators. The study found that the most attractive flowers are 100 times more attractive than the least attractive flowers. According to the study, the most attractive flowers are borage, lavender, marjoram, and open-flower dahlias. Majoram was the best all-round flower, attracting honey bees, bumble bees, other bees, hover flies, and butterflies. While information on pollinator friendly flowers is widely available, this study was […]

(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, 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 9, 2013) California Governor Jerry Brown has signed Assembly Bill 304, a bill designed to protect people from harmful pesticides identified as Toxic Air Contaminants (TACs). The bill will require the Department of Pesticide Regulation (DPR) to develop mitigation measures for the use of harmful pesticides that vaporize and drift from application sites. California, a major user of pesticidefumigants, has tried to tackle to prevalence of pesticide drift in the state, and is one of few states that monitor air-borne pesticides. AB 304: “Pesticides: toxic air contaminant: control measures” introduced by Assembly member Das G. Williams (D-Santa Barbara), gives the DPR two years to reduce the effects of harmful air toxins once the department determines that additional mitigation measures are necessary. Fumigants are some of the most dangerous pesticides on the market and include the controversial methyl iodide. They are applied in large quantities, vaporize easily, drift away and expose nearby farmworkers and other community members to harm, with health effects linked to headaches, vomiting, severe lung irritation, and neurological effects. Some fumigants are linked to cancer, reduced fertility, birth defects and higher rates of miscarriage. “Californians have a right to breathe clean air, and not worry […]

(Beyond Pesticides, October 8, 2013) Stress brought about by chronic exposure to sublethal levels of neonicotinoid pesticides causes bee colony failure, according to a new study published in the journal Ecology Letters. Scientists at Royal Holloway University of London have determined that low-level exposure to the pesticide imidacloprid at levels bees encounter in the field causes subtle impacts on individual bees that eventually cause colonies to collapse. This breakthrough study underlines repeated U.S. beekeeper and environmental group calls  for the Environmental Protection Agency (EPA) to  suspend the use of neonicotinoid pesticides, as the European Commission recently decided this past April. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD). Studies continue to link a class of systemic pesticides called neonicotinoids to the CCD phenomenon and pollinator decline in general. While scientists have cited multiple chemical and other factors that contribute to degrading bee health, until now no study has shown the internal mechanism within bee colonies that causes collapse. By focusing on chronic sublethal stressors, Royal Holloway researchers have addressed the complexities that […]

(Beyond Pesticides, October 4, 2013)  It was hoped that a  recent meeting in Florida between beekeepers and citrus growers could create stronger communication between both agricultural sectors. Beekeepers in Florida have begun to voice growing concerns over the increased use of insecticides on citrus trees where their bees are used as pollinators. Though this meeting worked to set up an important dialog between beekeepers and citrus growers, it focused predominantly on the effects of accidental exposure. This focus does not take into account the long-term residues these systemic insecticides can leave in the environment, contaminating nectar and pollen.     The recent September meeting that was organized by the Florida Agriculture Commissioner Adam Putman, a former U.S. congressman and citrus farmer, was meant to start a dialog between citrus growers and beekeepers. This dialog was viewed as necessary by Florida’s Department of Agriculture as beekeepers are worried over the increased use of insecticides in citrus groves. Recently, citrus farmers have increased their use of insecticides from several times a year to applications every month or greater to combat the invasive Asian citrus pysllids. Asian citrus pysllids can infect trees with a bacterium that causes citrus greening. Honey bees in Florida […]

(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 30, 2013) A new report, published by UCLA’s Sustainable Technology and Policy Program, finds that the California Department of Pesticides Registration (DPR) has failed to ensure that pesticides it approves are safe. Using methyl iodide as a case study, researchers point to key deficits in the approval process and make recommendations for improvements. Methyl iodide was used as a fumigant to control pests on strawberries, despite its threats to human health. It (i) causes miscarriages, thyroid dysfunction, and cancer, (ii) is neurotoxic, causing psychiatric symptoms and movement disorders similar to Parkinson’s disease,  and (iii)  is a developmental toxin that impairs fetal development. The fumigant was designed as a substitute for methyl bromide, which is slated for phase-out by 2015 as an ozone-depleting chemical under the Montreal Protocol. In the formulation, methyl iodide was combined with another fumigant, chloropicrin, to control for pests and approved for use by California DPR on December 2010, despite severe human health risks presented by scientists and substantial outcry by environmental and farmworker organizations. The report, entitled “Risk and Decision: Evaluating Pesticide Approval in California,” examines the effectiveness of DPR in registering pesticides. Most importantly, the report highlights the flawed risk assessment approach […]

(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, September 25, 2013) Five days after genetically engineered (GE) alfalfa was confirmed to have contaminated non-GE alfalfa in Washington State, the U.S. Department of Agriculture (USDA) announced it would not investigate the incident. Conventional and organic farmers have long been concerned with the economic impacts of GE adulteration, and this incident represents the latest in a long string of contamination events that have brought a global spotlight on the United States’ loose regulatory structure for these controversial crops. GE alfalfa is engineered by Monsanto to be resistant to glyphosate, or “Roundup Ready,” and is the first engineered perennial crop. The contamination could either be a result of cross-pollination or direct contamination of purchased seed. Cross- contamination is highly likely as alfalfa is pollinated by bees that can fly and cross-pollinate between fields and wild sources miles apart. According to a December 2011 report by Stephanie Greene, a Ph.D. geneticist with the USDA Agricultural Research Service (ARS), after Roundup Ready alfalfa was first deregulated in 2005 industry testing of conventional seed lots found levels of contamination as high as  two percent. USDA claims the contamination is a “commercial issue” and should be addressed by the marketplace and not the […]

(Beyond Pesticides, September 20, 2013) A study of women in Northern California farm towns finds that those living within three miles of strawberries fields treated with methyl bromide gave birth to smaller, lighter babies. Methyl bromides, a fumigant pesticide injected into soils to eliminate soil-borne pests, can volatize into the air exposing nearby neighborhoods. The U.S. and other developed countries have banned the use of methyl bromide under an international treaty that recognized the role of chemicals like methyl bromide to deplete the ozone layer. However, some farmers continue to use the fumigant on strawberries and other crops due to the “critical use exemption” (CUE) stipulation of the laws, which allows the chemical to continue to be used when there are no feasible alternatives. The study, published in Environmental Health Perspectives, examined the health of babies born to 442 pregnant women living in Salinas Valley, CA in 1999 and 2000, when methyl bromide was widely used.   Utilizing data from California’s Pesticide Use Reporting System, the study was able to identify residences that were within 5 kilometers of methyl bromide application. Researchers find that women exposed to the chemical during their second trimester have babies that are  four ounces lighter […]

(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, September 17, 2013) Last Friday, Health Canada released new measures the agency claims are intended to protect bees from exposure to neonicotinoid pesticides. As with recent regulations proposed by the U.S. Environmental Protection Agency (EPA), beekeepers and environmental groups are criticizing the measures as inadequate, not going far enough to protect domesticated honey bees that both in Canada and the U.S.  have seen losses of over 30% each winter since 2006. Ontario beekeeper Dave Schuit told the CBC, “Basically I see it as a Band-Aid. [The Pest Management Regulatory Agency] should’ve done their study before they approved this pesticide.” Dave Schuit owns Saugeen Country Honey Inc., and reportedly lost 37 million bees last year — more than half of his over 2,000 hives — as a result of exposure to neonicotinoid pesticides. Health Canada’s proposal includes: Requiring the use of safer dust-reducing seed flow lubricants (most corn and soy seed is coated with neonicotinod pesticides before planting and then mixed with a lubricant like talc that creates a toxic  dust in seed planters); Requiring adherence to safer seed planting practices; Requiring new pesticide and seed package labels with enhanced warnings; and Requiring updated value information be provided to […]
