Endocrine Disruptors Cost U.S. Billions in Health Care Costs and Lost Wages

Tuesday, October 25th, 2016

(Beyond Pesticides, October 25, 2016) Last week, a study,  Exposure to endocrine-disrupting chemicals in the USA: a population-based disease burden and cost analysis,  published in The Lancet  journal, concludes  that exposure to pesticides and other chemicals found in common household items, such as toys, makeup and detergent, costs the U.S. more than $340 billion annually in  health care costs and lost wages. The chemicals in question, endocrine disruptors (EDCs), interfere with the body’s hormone system, which can lead to a variety of health problems. According to Environmental Health News, the researchers estimate the costs by looking at exposure data and then projecting 15 medical conditions that are linked to endocrine disruptors and their associated health costs and lost wages. The findings came from calculations made by the Endocrine Society, the World Health Organization, and the United Nations Environment Program. A group of flame retardant chemicals called polybrominated diphenyl ethers (PBDEs) were the worst offenders in the U.S., accounting for nearly two-thirds of estimated health problems. These chemicals were estimated to annually cause about 11 million lost IQ points and 43,000 additional cases of intellectual disability, costing around $268 billion. Pesticide exposure, the second most costly chemical group in the U.S., […]

New Study Shows Reduction of Persistent Pollutants in Breast Milk, Though Concerns Remain

Thursday, October 20th, 2016

(Beyond Pesticides, October 20, 2016) Researchers at the University of Western Australia (UWA) and Murdoch University recently released a study whose findings show that levels of pesticides in breast milk have dropped significantly over the past forty years, though some major concerns remain. Published in the international journal Chemosphere, the research shows a 42-fold decrease in levels of pesticides detected in breast milk, and ties the reduction to government efforts to prohibit persistent organic pollutants (POPs) in Australia, which has lead to decreased exposure over time. Led by UWA’s internationally renowned human lactation researcher Emeritus Professor Peter Hartmann, Dr. Donna Geddes and Murdoch’s Associate Professor Robert Trengove, the study is a testament to the positive impact banning pesticides can have on the health of individuals, especially vulnerable populations like infants, but also shows that there is a long way to go before our bodies are void of any bioaccumulated toxic residues. Researchers often study breast milk because it can bioconcentrate, or accumulate, persistent organic pollutants (POPs). Multiple studies on breast milk have been performed throughout the years, many of them confirming the fact that common toxic chemicals, such as glyphosate and triclosan, build up in our bodies over time. Most […]

78 Commonly Used Agricultural Pesticides Linked to Wheezing

Thursday, August 11th, 2016

(Beyond Pesticides, August 10, 2016) New research connects 78 pesticides commonly used by farmers with many adverse respiratory effects, including both allergic and non-allergic wheeze. The study, Pesticides Are Associated with Allergic and Non-Allergic Wheeze among Male Farmers, was led by NC State environmental epidemiologist, Jane Hoppin, ScD and colleagues from the National Institute of Environmental Health Sciences (NIEHS), the National Cancer Institute, Westat and the National Institute for Occupational Safety and Health (NIOSH). This is one of the most comprehensive evaluations of pesticides in relation to wheeze that has been evaluated to date, finding that several commonly used pesticides in both agriculture and residential settings can cause adverse respiratory effects. “Fifty-one of the pesticides we tested in this study had never been analyzed in terms of their effects on respiratory outcomes. And some of them, like glyphosate, 2,4-D and permethrin, aren’t just used on farms. They’re used residentially now to kill weeds or treat fleas on pets,” said Dr. Hoppin. “We believe it’s important information that will help people make decisions about pesticides.” Researchers used interview data from the 2005-2010 Agricultural Health Study (AHS) to assess the correlation between pesticide exposure and wheeze in male farmers. 22,134 farmers were […]

Fighting Zika – Growing Concerns over Pesticide Resistance

Friday, August 5th, 2016

(Beyond Pesticides, August 5, 2016) Concerned health officials in Miami, Florida are investigating suspicions that Zika-spreading mosquitoes have become resistant to the pesticides commonly used synthetic pyrethroid insecticides used in mosquito control. As the region works to contain a Zika outbreak in northern Miami, officials are beginning to recognize that broadcast pesticide applications are not effective at controlling populations, and are looking into cases in the U.S.  and in other parts of the world of mosquitoes developing resistance to chemical controls, or whether other factors are at work. At the same, the broadcasting of the pesticides by truck and plane and the resulting exposure to people and the environment also raise serious health issues. The Aedes aegypti mosquito, which has the ability to live indoors and reproduce even in tiny pools of water, is the primary way the Zika virus is spread, although there are reports that the disease can also be transmitted through sexual contact. Zika virus has been linked to cases of microcephaly, in which babies are born with underdeveloped brains. The virus has been detected in several Latin American countries, including Brazil where the outbreak was first observed and linked to increased cases of microcephaly. However, locally […]

Study Adds to Findings that Link Prenatal Pesticide Exposure to Lower IQs

Friday, July 29th, 2016

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

Common Pesticide Exposure Alters Behavior of Fish and Amphibians

Tuesday, July 19th, 2016

(Beyond Pesticides, July 19, 2016) Exposure to common pesticides at levels often found in the environment can have subtle but significant impacts on the behavioral health of fish, amphibians and other aquatic invertebrates. According to researchers at Northern Arizona University, who analyzed data from nearly 40 experiments to reach their conclusion, fish and amphibians swam 35% slower and were 72% less active after pesticide exposure. Chemical Class Type Example Pesticides Carbamates Insecticide Carbaryl, Aldicarb Organochlorine Insecticide DDT, Endosulfan, Chlordane Organophosphates Insecticide Diazinon, Chlorpyrifos Organotins Biocide Tributyltin Phosphonoglycines Herbicide Glyphosate, Glufosinate Pyrethroids Insecticide Permethrin, Bifenthrin, Esfenvalerate Triazines Herbicide Atrazine, Simazine The study, published in Science of the Total Environment, found that the overall effect on aquatic wildlife varied based on the chemical class the animals encountered. While pyrethroids, carbamates, and organophosphates resulted in a significant decrease in swim speed, triazines and phosphonoglycines showed no overall effect. Pyrethroids, carbamates, organophosphates, organochlorines, and organotins decreased activity, while phosphonoglycines had no overall effect, and triazines actually increased activity. “I didn’t think that we would see [an effect] across such a wide range of pesticides so consistently, but we did,” said study co-author, Catherine Propper, PhD to KNAU, “and that leads to some concerns about […]

EPA Finds 97% of Endangered Species Threatened by Common Pesticides

Tuesday, April 12th, 2016

(Beyond Pesticides, April 12, 2016) Two commonly used pesticides are “likely to adversely affect” 97% of species listed under the Endangered Species Act (ESA), according to a first of its kind national assessment by the U.S. Environmental Protection Agency (EPA). The determination is part of a settlement reached by EPA and the Center for Biological Diversity, which requires the agency to complete a review of the impact of organophosphate pesticides chlorpyrifos, malathion, and diazinon by December 2017, and two carbamate class pesticides, methomyl and carbaryl, by the end of 2018. Under ESA Section 7, any agency action that it  authorizes, funds, or carries out must find that it  “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” Under ESA, EPA is required to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) when registering a pesticide, in order to mitigate risks to endangered species. However, EPA routinely disregards this requirement, and has been sued numerous times for failing to ensure adequate protections for endangered species. Although CBD’s original lawsuit targeted potential pesticide impacts on California’s threatened red-legged frog, […]

Chlorpyrifos Reduces Memory and Learning in Exposed Bees

Friday, March 4th, 2016

(Beyond Pesticides, March 4, 2016) Honey bees experience a learning and memory deficit after ingesting small doses of the insecticide  chlorpyrifos, potentially threatening their success and survival, according to a study in  New Zealand. Chlorpyrifos is a highly neurotoxic organophosphate pesticide used worldwide on crops to protect against insects and mites. The study,  Measurements of Chlorpyrifos Levels in Forager Bees and Comparison with Levels that Disrupt Honey Bee Odor-Mediated Learning Under Laboratory Conditions,  published in  Ecology, examines chlorpyrifos levels in  bees collected from 17 locations in Otago, New Zealand and compared doses of the pesticide that cause sub-lethal effects on learning performance under laboratory conditions with amounts of chlorpyrifos detected in bees in the field. Researchers found chlorpyrifos in 17% of the sites sampled and 12% of the colonies examined. Honey bees are found to experience harmful effects to smell memory and learning, and reduction in specificity of memory recall. Chlorpyrifos is just one of many pesticides that have frequently been detected in honey bees. According to a study conducted last year by the U.S. Geological Survey (USGS), 72% of bees tested positive for pesticide residues, raising concerns about  unintended pesticide exposures where land uses overlap or are in proximity […]

Montreal, Canada Proposes “Complete Ban on Neonics”

Tuesday, December 15th, 2015

(Beyond Pesticides, December 15, 2015) Last week Montreal, the largest city in Canada’s Quebec province, announced plans for an all-out ban on the use of bee-toxic neonicotinoid pesticides. The new regulations represent the strongest move against this neurotoxic class of insecticides by any government entity to date. Environmental and health advocates are praising the ban as a sign that more and more localities in North America are finding these chemicals unnecessary to manage pest problems, and not worth the risk to pollinators and other wildlife. Montreal’s regulations provide for a complete ban, “without exception,” on the use of neonicotinoids outside of buildings on City land. Prior to the new rules, private citizens and businesses could obtain a temporary permit for the use of neonicotinoids in the  case  of an infestation, however, the permit will no longer be available and citizens will be encouraged to employ alternative practices or products. The ban will also apply to golf courses and properties in the City used for agricultural and horticultural purposes. “By adopting a regulation that prohibits the use of such pesticides in Montreal, our Administration places the health of its citizens, the quality of life of its neighborhoods and the preservation of […]

Scientists Find Pesticide Exposure Decreases Lung Function in Children

Tuesday, December 8th, 2015

(Beyond Pesticides, December 8, 2015) Exposure to common agricultural pesticides in early life leads to a measurable decrease in children’s lung functioning, according to researchers from the University of California, Berkeley. Organophosphate pesticides, a relatively older generation of crop chemicals still widely used on farms in California, have been associated with a broad range of diseases in both children and adults. This latest study adds to calls from health and environmental advocates to eliminate these toxic pesticides in agriculture, and move towards safer, sustainable, and organic management practices. The higher the rate of organophosphate exposure, the smaller a child’s lung capacity would be, scientists found. The UC Berkeley study traces exposure by looking at pesticide metabolites in urine five  times over the course of childhood (6 months to 5 years). Participants were part of the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS), a longitudinal birth cohort study investigating the effects of pesticides and other environmental chemicals on the growth, health, and development of children in California’s Salinas Valley. For every 10-fold increase in pesticide metabolites measured in a child’s urine, an average of approximately 8% air function within the lungs was lost. “Researchers have described […]

EPA Takes Long-Awaited Action to Eliminate Neurotoxic Chlorpyrifos in Agriculture

Tuesday, November 3rd, 2015

(Beyond Pesticides, November 3, 2015) The U.S. Environmental Protection Agency (EPA) is proposing to revoke all food tolerances for the organophosphate insecticide chlorpyrifos (also known as Dursban), a neurotoxic pesticide produced by Dow AgroSciences that poses particular risks to children and farmworkers. If EPA’s rule is finalized, chlorpyrifos would be effectively eliminated from use in agriculture 15 years after consumer uses were discontinued. However, other non-food uses, including golf courses, turf, green house and mosquito control are not affected by this decision and will remain. EPA’s proposed rule came on the day of a court-ordered deadline from the U.S. Court of Appeals Judge for the Ninth Circuit, M. Margaret McKeown. In August of this year, Judge McKeown ordered EPA to respond to a petition filed by Pesticide Action Network North America and the Natural Resources Defense Council nearly nine years ago. The lawsuit called on the agency to ban all uses of the insecticide in light of scientific evidence and public comments ignored by the agency after its cumulative risk assessment for organophosphate insecticides. In 2012, EPA imposed “no-spray” buffer zones around public spaces, including recreational areas, schools, and homes to reduce bystander exposure risks. Earlier this year, the agency […]

Another Study Confirms Eating an Organic Diet Lowers Pesticide Levels in Children

Wednesday, October 14th, 2015

(Beyond Pesticides, October 14, 2015) New research from the Center for Environmental Research and Children’s Health (CERCH) shows that children, especially those in low-income and agricultural families, who switched to an organic diet reduced their bodies’  level of pesticides. This California study is one of several that documents the benefits of eating an organic diet, especially for children who are especially vulnerable to pesticide exposures due to the developing bodies. The study, Effect of Organic Diet Intervention on Pesticide Exposures in Young Children Living in Low-Income Urban and Agricultural Communities  follows 40 children, 3-6 years old from low-income families living in urban and agricultural environments in Oakland and Salinas, California. The children alternated between a conventionally grown diet and organic, and urine samples were analyzed each day. The researchers measure 23 metabolites of several pesticides classes, including organophosphates (OP) and pyrethroid insecticides, and the herbicides 2,4-D and metolachlor. These pesticides are frequently detected (> 72%) in urine samples collected, with metabolites of 2,4-D detected 90 percent of the time, and pyrethroids 82 percent. Overall, among the most frequently detected pesticides, metabolites of OPs  decreases by nearly 50 percent when children are on an organic diet, and levels of 2,4-D falls […]

EPA Seeks Public Opinion on Continued Use of Neurotoxic Organophosphate Pesticides

Friday, October 9th, 2015

(Beyond Pesticides, October 9, 2015) Last week, the Environmental Protection Agency (EPA) released preliminary human health and ecological risk assessments for seven organophosphate pesticides (OPs) and announced the public open comment period for those chemicals. These risk assessments come as a result of the required periodic registration review, as required by  the Federal Insecticide, Fungicides, and Rodenticide Act. In general, OPs are highly toxic and many have been voluntarily removed from the market, considerably restricted, or denied reregistration. Unfortunately, EPA continues to rely on risk mitigation for individual OPs instead of phasing them out altogether. Seven OPs ­ ­—dimethoate, dictrotophos, chloyrophos-methyl, tribufos, terbufos, profenofors, and ethoprop—are among the first wave of chemicals whose preliminary risk assessments have been completed under the registration review program. Each of these was found by EPA to inhibit the enzyme acetylcholine esterase (AchE), which ultimately leads to neurotoxic  central nervous system effects. This information is not new, however. In 2012, University College London found long-term low-level exposure to OPs produces lasting damage to neurological and cognitive functions. In 2013, at least 25 children died after eating school lunches contaminated by OPs. One OP in particular, chlorpyrifos, chlorpyrifos (Dursban), is currently under petition for the same […]

Yale Study Links Prenatal Pesticide Exposure to Tremors in Children

Monday, October 5th, 2015

(Beyond Pesticides, October 05, 2015) According to a Yale University study, prenatal exposure to the widely used agricultural pesticide chlorpyrifos is linked to tremors — involuntary contraction or twitching of muscles — in childhood. Chlorpyrifos, a broad-spectrum chlorinated organophosphate insecticide also known as Dursban, may also affect the cardiovascular and respiratory systems and is acutely toxic to bees, birds, mammals, and aquatic life. The study, titled Prenatal exposure to the organophosphate pesticide chlorpyrifos and childhood tremor  and published in the journal Neurotoxicology, measured the presence of chlorpyrifos in umbilical cord blood samples in 263 low-income, inner-city minority children. In 2001, the U.S. Environmental Protection Agency (EPA) banned residential use of chlorpyrifos, which was prominent in urban areas at the time. However, the study participants  —263 minority mothers  and their children, all from low income  communities in New York  City— were assembled in 1997,  before the ban was imposed. In  1997, the initial measure of each  child’s prenatal exposure to CPF  was taken from umbilical cord  blood. The children were then followed until approximately 11 years of age, after which they underwent a neurophysical assessment, which included a short drawing test. Researchers found that compared to all other children, those who […]

California to List Glyphosate (Roundup) as Cancer-Causing

Thursday, September 10th, 2015

(Beyond Pesticides, September 10, 2015) Last week, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate (Roundup) and three other chemicals as cancer-causing chemicals under California’s  Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Glyphosate  is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth. Under California law, Proposition 65 requires that certain substances identified by the International View postAgency for Research on Cancer (IARC) be listed as known cancer-causing chemicals. In March, a study by the IARC classified glyphosate as a Group 2A material, which means that the chemical is carcinogenic based on sufficient evidence of carcinogenicity in experimental animals. The agency considered the findings from an EPA Scientific Advisory Panel report, along with several recent studies in making its conclusion. However, industry supporters of glyphosate all over the globe are conducting their own studies to attempt to prove that it is not a carcinogen. These studies, like one by German Federal Institute for Risk Assessments (BfR), are based almost solely on industry science and classified industry reports, each of which might not consider critical variables. With more glyphosate-focused studies being released, the growing evidence […]

Lice Found Resistant to Common Insecticide Treatment

Thursday, August 20th, 2015

(Beyond Pesticides, August 20, 2015) Just as children go  back to school, research  finds that lice in 25 of 30 states in a  U.S. study have developed resistance to common over-the-counter treatments like permethrin, calling into questions the justification for exposing children to a neurotoxic and carcinogenic pesticide and elevating the need to consider nontoxic alternatives. The  research was presented Tuesday at the 250th National Meeting and Exposition of the American Chemical Society (ACS), by Kyong Yoon, Ph.D., of Southern Illinois University, Edwardsville. Classified as a synthetic pyrethroid insecticide, permethrin is “likely carcinogenic” and a suspected endocrine disruptor, immunotoxic, neurotoxic, and highly toxic to fish, aquatic animals, and bees. Dr. Yoon and his colleagues describe the threefold mutations that lice have developed over time due to the constant use of synthetic pyrethroid insecticides. This new finding builds on his team’s previous research, which found that 99.6% of lice are resistant to chemical treatment, adding weight to the fact that chemical treatments not only are unnecessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim. “We are the first group to collect lice samples from a large number of populations across the U.S.,” […]

Court Ordered Deadline Mandates EPA Action on Toxic Insecticide Dursban

Thursday, August 13th, 2015

(Beyond Pesticides, August 13, 2015) On Monday, a federal appeals court judge mandated that the U.S. Environmental Protection Agency (EPA) respond to a petition filed nearly nine years ago that seeks  to force the agency to restrict  the dangerous insecticide  chlorpyrifos (an organophosphate also known as Dursban). U.S. Court of Appeals Judge for the Ninth Circuit, M. Margaret McKeown,  delivered her opinion on August 10, stating that federal agencies should never practice the “venerable tradition” of putting off statutory requirements  when it comes to human health. The court issued the opinion and order in a lawsuit brought by Earthjustice on behalf of Pesticide Action Network (PAN) and Natural Resources Defense Council (NRDC), and gives EPA until October 31 to finally respond to the petition requesting to ban chlorpyrifos. EPA took a tentative step towards further regulating chlorpyrifos in a July 2015 announcement to ban remaining agricultural uses by April 2016 date. Unhappy with the uncertainty that EPA delivered, the court felt that a mandated deadline would expedite the process. On June 8, 2000, EPA administrator Carol Browner announced a voluntary agreement between the agency and industry leaders, including Dow AgroSciences, to ban all home and garden uses of Dursban, which […]

Despite Known Hazards, EPA Waits Decades for Manufacturers to Withdraw Pesticide

Wednesday, July 8th, 2015

(Beyond Pesticides, July 8, 2015)  Last week, after decades of review and known toxic hazards, especially to children, the Environmental Protection Agency (EPA) accepted a proposed cancellation for  a number of indoor uses (including food establishments) and tolerances of propoxur, a carbamate insecticide known for its toxic effects to  children. EPA has received a Section 6(f) request under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) from the registrant of propoxur to voluntarily cancel certain uses of the carbamate insecticide. The request from the manufacturer, Wellmark International, requests cancellation of  indoor aerosol, spray and liquid formulations of propoxur, indoor crack and crevice use, and all use in food-handling establishments.  EPA previously agreed to an April 1, 2016 phase out of propoxur in pet collars, but has continued to leave open these other avenues of exposure. The agency will begin accepting comments on its  proposal once it has been published in the Federal Register, which is expected to occur within 10 days of the prepublication signature date. It should be noted that EPA engages in lengthy negotiations with pesticide manufacturers, as is the case with propoxur (see recent announcement on chlorpyrifos), rather than pursuing rigorous regulatory standards through its cancellation or […]

EPA Falters Again in Banning Remaining Uses of a Highly Toxic and Unnecessary Insecticide

Tuesday, July 7th, 2015

(Beyond Pesticides, July 7, 2015) In a sleight of hand,  the U.S. Environmental Protection Agency (EPA) announced plans last week to cancel all remaining agricultural uses of the hazardous insecticide chlorpyrifos by April 2016, and then left the door open for negotiations with the chemical’s manufacturer, Dow AgroSciences, to adopt  risk mitigation measures that would avoid a ban. Environmental groups are reacting to EPA’s announcement with guarded optimism, encouraging the agency to move forward with its planned cancellation of a highly toxic chemical that has remained on the market for far long. In June 2000, EPA announced a negotiated voluntary cancellation  with Dow that removed residential uses of chlorpyrifos (Dursban) from the market because of the neurotoxic effects to children, but allowed most agricultural uses to continue. As early as January of this year, EPA released a revised human health risk assessment for chlorpyrifos, finding that the chemical poses risk to farmworkers, and the drinking water of small watersheds. The assessment was, in part, in response to a petition submitted by Natural Resources Defense Council (NRDC) and Pesticide Action Network (PAN) in 2007, which called on the agency to ban all uses of the insecticide. Since the the 2000 cancellation, […]

Pyrethroid Pesticide Use Increases Rates of ADHD in Adolescent Boys in New Study

Thursday, June 4th, 2015

(Beyond Pesticides June 4, 2015) Another study has found links between a commonly used household pesticide and attention deficit hyperactivity disorder (ADHD) in children and young teens. Researchers at Cincinnati Children’s Hospital Medical Center found an association between pyrethroid pesticide exposure and ADHD, particularly in terms of hyperactivity and impulsivity. These results reinforce the findings of a study led by a research team at Rutgers University earlier this year that found links between the pesticide deltamethrin and ADHD. In 2001, over concerns about adverse health consequences, the U.S.  Environmental Protection Agency banned several commonly used organophosphate (organic compounds containing phosphorus) pesticides from residential use due to the chemicals neurotoxic properties. The ban led to the increased use of pyrethroid pesticides, which are now the most commonly used pesticides for residential pest control and public health purposes. Pyrethroids, like deltamethrin, are commonly used in the home,  office buildings,  and on vegetable crops, gardens, lawns and golf courses. This shift to predominantly using pyrethroids is troubling, as they have oft been promoted as a safer choice than banned organophosphates, despite the fact that they pose many real threats to human health. Many recent studies show significant concern with this class of chemicals, […]

California Regulators to Strengthen Pesticide Restrictions Near Schools

Wednesday, June 3rd, 2015

(Beyond Pesticides, June 3, 2015) After years of campaigning by local activists and a lawsuit filed by parents citing discriminatory practices from policies that led to disproportionate exposure of Latino children to pesticides, the California Department of Pesticide Regulation (CDPR) will now seek to gather input from stakeholders to determine what measures are appropriate to enhance protection of California’s schoolchildren. Given that Latino children are more likely to attend schools near areas with the highest use of pesticides of concern, and California’s pesticide use has actually increased over recent years, the state will need strong restrictive policies to provide any meaningful protections for school children. According to CDPR, the agency will hold five  workshops from May 28 – June 9 2015 to gather input that will later help craft a statewide regulation on  pesticide use near schools, with a focus  on improving school pesticide notification procedures and reducing the risk of exposure. In California, many schools have been built on prime agricultural land next to farm operations. While there are currently state regulations on the use of individual pesticides, CDPR’s regulatory framework for restricted pesticides also allows for the establishment of additional rules to address local conditions. However, existing rules […]

California Department of Pesticide Regulation Report Raises Concerns Over Increased Pesticide Use

Thursday, May 21st, 2015

(Beyond Pesticides, May 21, 2015) The California Department of Pesticide Regulation (CDPR) published its Annual Pesticide Use Report last week, which finds that overall pesticide use for agricultural purposes has increased by 3.7 percent between 2012 and 2013. Pesticide use increased by 6.4 million pounds in 2013, the most recent data available, making for a grand total of 178 million pounds of pesticides used annually in California’s agricultural industry. The study also revealed several insights on trends in pesticide use, the most troubling of which is the increased use of organophosphates, and more specifically, the insecticide chlorpyrifos. This raises concerns that, absent aggressive efforts by CDPR to ban chlorpyrifos’ use in food production, industry reliance on the pesticide may continue to  increase. Chlorpyrifos was banned by the Environmental Protection Agency (EPA) for nearly all residential uses in 2000, but since then has remained widely available for agricultural use. Efforts to limit the agricultural use of chlorpyrifos in the state of California have been in the works since the fall of 2014, and a regulation Designating Chlorpyrifos as a Restricted Material was recently adopted by California’s DPR.  The new regulation classifies as  ”˜restrictive use’  all pesticide products containing the organophosphate  insecticide […]

Pesticide Residues on Foods Shown to Affect Sperm Quality

Wednesday, April 1st, 2015

(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 […]
