(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 […]

(Beyond Pesticides, November 1, 2012) Conservation groups and fisherman have filed lawsuits against U.S. Environmental Protection Agency (EPA) demanding that pesticide restrictions be implemented around salmon streams. Regulatory buffers surrounding streams and watersheds have not been fully implemented by EPA, though it is required to by law. The National Marine Fisheries Service (NMFS), which promotes sustainable fisheries, recovery of protected species, and the health of coastal marine habitats, commented that common pesticides should not be sprayed within 500 to 1000 feet of waterways. Its comments focused on the impacts of chlorpyrifos, diazinon and malathion, which jeopardize the health of federally protected salmon species. Despite this and other evidence that supports the need for buffer zones, EPA has withheld action until the 4th U.S. Circuit Court of Appeals resolves the case. EPA is mandated by law to protect dwindling species like salmon under the Endangered Species Act. Salmon, in particular, are a good indicator of how well we are taking care of both the marine and terrestrial ecosystems, because they live in streams, lakes, rivers, estuaries, and open ocean. They are also extremely sensitive to changes in water quality and upstream changes to the river flow, turbidity, and temperature. It goes […]

(Beyond Pesticides, October 24, 2012) The American Academy of Pediatricians (AAP) has weighed in on the organic food debate recognizing that lower pesticide residues in organic foods may be significant for children. The Academy also notes that choosing organic is based on larger environmental issues, as well as human health impacts like pollution and global climate change. This is the first time the AAP has made a statement on organic foods, concluding that the most important thing for children is to eat a wide variety of produce, and that pediatricians should talk to their patients about the potential health and environmental benefits of choosing organic. There have been conflicting media reports of the American Academy of Pediatrics’ (AAP) recent report on organic foods, published online in Pediatrics. However, the academy is clear that organic foods do provide health advantages by way of reducing exposure to pesticides, especially for children, even reporting “sound evidence” that organic foods contain more vitamin C and phosphorus. According to the report, “in terms of health advantages, organic diets have been convincingly demonstrated to expose consumers to fewer pesticides associated with human disease. Organic farming has been demonstrated to have less environmental impact than conventional approaches.” […]

(Beyond Pesticides, October 19, 2012) School is a place where children need a healthy body and a clear head in order to learn. Despite a successful trend toward nonchemical strategies, pesticides remain prevalent and are widely used today in universities, schools, and daycare facilities. Kelsey Crain, an undergraduate student at University of Delaware, first became aware of the issue when, “I noticed there was this weird rash on my legs which wasn’t there before I was on The Green.” Kayla Iuliano, Crain’s friend and reporter at the student-run University of Delaware Review, probed the University about why there was no notification, and in return was given standard bureaucratic prose: “University Spokesman John Brennan stated in an email message that workers are not required to post signs when areas are sprayed because the chemicals are not harmful when used properly, and personnel are trained in how to apply them,” she wrote in the University of Delaware Review. “He said the sprays are commonly used commercial products and are registered for use with the Environmental Protection Agency. ”˜They are recognized in the industry as safe when applied as directed’.” The pesticide widely applied to the Green is called “PowerZone,” which is composed […]

(Beyond Pesticides, October 10, 2012) U.S. Department of Agriculture (USDA)-certified organic growers in the United States sold more than $3.5 billion organically grown agricultural commodities in 2011, according to the results of the 2011 Certified Organic Production Survey, released by USDA’s National Agricultural Statistics Service (NASS). The data shows a general upward trajectory for certified organic production and produce in the U.S. NASS conducted the survey for USDA’s Risk Management Agency to help refine federal crop insurance products for organic producers. Organic sales totaled more than $3.53 billion last year, about 0.9 percent of total U.S. farm receipts, and an increase from 2008 reports. The 2011 Certified Organic Production Survey provides acreage, production, and sales data for a variety of certified organic crops and inventory and sales data for selected certified organic livestock commodities. In addition, data on land in farms, participation in federal farm programs, and marketing practices on certified organic farms are included. The 2008 Certified Organic Production Survey, the first organic production survey conducted by NASS, reported certified and exempt organic farms had $3.16 billion in total sales —$1.94 billion in crop sales and $1.22 billion in sales of livestock, poultry and their products. In 2008, organic […]

(Beyond Pesticides, October 4, 2012) The Centers for Disease Control and Prevention (CDC) has released updated tables for its Fourth National Report on Human Exposure to Environmental Chemicals, which was released in 2009. The new data includes updated tables for 119 chemicals and tables for 34 new chemicals, including updates for 2,4-D and triclosan and their metabolites. New metabolites of organophosphorous insecticides are added for the first time. Notably, the report found that concentrations of four metabolites of organophosphates generally increased among nearly all groups CDC measured, while levels for two generally decreased. Organophosphate pesticides, such as chlorpyrifos, are highly toxic to humans and the environment. Chlorpyrifos is a frequent water contaminant and a long range toxicant, exposing communities and polluting pristine areas far from where it was applied. Volatilization drift ””the evaporation of the pesticide after application”” is also part of the problem for chlorpyrifos. A 2009 study found the pesticide to have significant impacts on the growth and development of amphibians miles away from the site where it was first applied. A USGS study in 2007 concludes that the breakdown products of chlorpyrifos are up to 100 times more toxic than the original. The Updated Tables, September 2012, […]

(Beyond Pesticides, September 11, 2012) Lawn company giant, Scotts Miracle-Gro Co., pleaded guilty to numerous charges of misleading consumers with unapproved labels and falsifying insecticide registrations, including using toxic chemicals in wild bird food. Scotts was ordered to pay $12.5 million in criminal fines, the largest penalty ever set under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Scotts admitted to using Storcide II and Actellic 5E to prevent insects from damaging the bird food in storage, even though it knew both chemicals were toxic to birds, fish, and other wildlife. In 2008, Scotts Miracle-Gro ceased sales of the tainted birdseed but not before 70 million units of the pesticide-tainted food was sold. The sentence imposed in federal court in Columbus, Ohio, includes a $4 million criminal fine, the Justice Department said. Separately, the company agreed to pay more than $6 million in civil penalties to the U.S. Environmental Protection Agency (EPA) and contribute $500,000 to organizations to protect bird habitats and restore and protect 300 acres of land to prevent runoff of pesticides into waterways —valued at $2 million. EPA has identified more than 100 products produced or sold by Scotts Miracle-Gro that violated the federal pesticide laws over […]

(Beyond Pesticides, September 4, 2012) After considering comments from growers and other stakeholders, including over 2,000 emails generated from Beyond Pesticides’ supporters on the recent proposal to reverse a decision to end the use of the organophosphate insecticide azinphos-methyl (AZM), the U.S. Environmental Protection Agency (EPA) has once again come to the conclusion that the chemical presents health risks to workers and can cause negative ecological impacts, while effective alternatives to this insecticide are available to growers. The agency has decided to maintain the initial September 30, 2012 date for cancellation of the remaining uses of AZM, on apples, blueberries, sweet and tart cherries, parsley, and pears. Though this represents a victory for farmworkers and health and environmental advocates, EPA has decided to allow growers to use only existing stocks of AZM in their possession for another year, through September 30, 2013, citing unusually bad weather conditions throughout 2012. All the required mitigation measures now reflected on AZM labeling will remain in effect during this use. Distribution or sale of AZM after September 30, 2012 remains prohibited. Due to industry pressure, the agency initially announced that it was conducting a new risk-benefit analysis (analysis of the impacts of cancellation) and […]

(Beyond Pesticides, August 28, 2012) New research reveals that bats may be at greater risk from pesticide exposure than previously suspected. When foraging at dusk, bats can be exposed to agricultural chemicals by eating insects recently sprayed with pesticides. A study from the University of Koblenz-Landau in Germany reveals that bats, due to their long life span and tendency to only have one offspring at a time, are particularly sensitive to reproductive effects from pesticides. The study, “Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard,” published in Environmental Toxicology and Chemistry, details the health effects of bats foraging on insects in an apple orchard after it was sprayed with the insecticides fenoxycarb and chlorpyrifos. After field applications of the pesticides, scientists measured the remaining chemical residues on flies, moths and spiders for two weeks. The highest residues were recorded on leaf dwelling insects and spiders, while lower contamination was found for flying insects. Based on this data scientists calculated exposure scenarios for different bat species, each with different feeding habits, and found that those which fed off insects from the leaves of fruit trees to be most affected. Researchers indicated that current […]
