(Beyond Pesticides, April 13, 2012) A study has found that the children of flower plantation workers in Ecuador are neurologically affected by the pesticide residues that their parents unwittingly carry home on their clothes, tools, and skin. The study documents significantly reduced activity for the essential enzyme acetycholinesterase (AChE) in children whose parents work on flower plantations compared to others whose parents do not. The two main classes of pesticides that the researchers identify as used in the region’s flower production, organophosphates and carbamates, are known to suppress the enzyme’s activity. AChE activity is crucial to healthy neurological functioning in humans and its suppression during childhood can hinder nervous system and cognitive development causing immediate and long-term impairment. In the study, Lower acetylcholinesterase activity among children living with flower plantation workers (Environ Res. 2012 Apr;114:53-9. Epub 2012 Mar 10), children whose parents work on a flower plantation are more than three times more likely to be in the group of lowest AChE activity. Additionally, the children who live the longest with a flower plantation worker are four times more likely to have lower enzyme activity than children who never live with a plantation worker. The researchers obtained their results by […]

(Beyond Pesticides, April 9, 2012) A new study finds that exposure of pregnant women to organophosphate (OP) pesticides —a widely used class of pesticides in North American agriculture— may affect both length of pregnancy and birth weight. Environmental Health Perspectives published the paper, “Associations of Prenatal Exposure to Organophosphate Pesticide Metabolites,” last Thursday, April 5, 2012. The study, by a Simon Fraser University researcher, finds that the population of 306 women in Cincinnati, Ohio, is representative of the type of exposures most North American women and their children experience. Although the use of OPs in Canada and the U.S. has declined in recent years, exposures remain widespread, and these findings add to growing evidence about the harmful effects of low-level exposures to environmental toxicants. The researchers collected urine from each of the women in Cincinnati twice during their pregnancies for organophosphate metabolites as well as other factors that could influence the fetus’ health, including exposure to second hand smoke, race, and poverty. Women with higher levels of organophosphates were found to have pregnancies that were three to four days shorter and babies that were about â…“ pound lighter on average than women with lower levels of pesticides. “For an individual […]

(Beyond Pesticides, February 15, 2012) California mosquito control agencies are charging that new NPDES permitting regulations would eliminate West Nile virus fogging and jeopardize public health. In response, the state of California has proposed to scale-back pesticide regulations, easing rules on fumigating adult mosquitoes. This is in spite of the high risk for further degradation of already contaminated surface waters in the state, and contrary to the stipulations and protections set out in the Clean Water Act. The current federal National Pollutant Discharge Elimination System (NPDES) permit, which recently went into effect after much resistance from the pesticide and agriculture industry and intensive lobbying efforts in Congress, does not authorize the discharge of biological and residual pesticides or their degradation by-products to waters of the U.S. that are impaired by the same pesticide active ingredients or any pesticide in the same chemical family. ”˜Impaired waters’ are polluted waters, i.e. those waters not meeting water quality standards pursuant to section 303(d) of the Clean Water Act (CWA). The NPDES permit is authorized under the CWA to require pesticide applicators to apply for permits before applying pesticides on or near surface waters. This process involves keeping records of pesticides used and monitoring […]

(Beyond Pesticides, February 3, 2012) A new study recently published in the Journal of Integrated Pest Management (JIPM) shows that from 2003 to 2008 the use of insecticide active ingredients was reduced by about 90% in University of Florida (UF) housing buildings after an Integrated Pest Management (IPM) program was implemented. The results of the study show that pest pressure was effectively managed throughout this period as well. These findings demonstrate that IPM can be an effective management tool for institutional pest problems, confronting pests while reducing human exposure to dangerous chemicals. IPM is a systematic approach to managing pests based on long-term prevention or suppression by a variety of methods that are cost effective and minimize risks to human health and the environment. The goal of urban IPM is to manage pests primarily by prevention and elimination of their access to food, water and harborages, exclusion techniques that seal entryways, as well as changes in human behavior. Low-toxicity insecticides were used only when necessary. In their article “Advancement of Integrated Pest Management in University Housing,” the JIPM authors find that the IPM program helps to virtually eliminate the use of hydramethylnon, borate, desiccants, organophosphates, fipronil, and pyrethroids, and they […]

(Beyond Pesticides, January 31, 2012) The Environmental Protection Agency (EPA) has proposed an expansion in pyrethrins/pyrethroid insecticide uses as part of its cumulative risk assessment for this neurotoxic class of chemicals. In the cumulative risk assessment, EPA concludes that pyrethroids “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. It went as far as to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. The agency is accepting public comments through February 8, 2012. Tell EPA that it has ignored numerous health effects and that these pesticides do pose unacceptable risks to human health given the availability of alternatives. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. In its comments to EPA, Beyond Pesticides states: There are several major concerns and flaws plaguing this cumulative assessment, which therefore does not meet the regulatory burden in fully evaluating synthetic pyrethroids’ effect on public and […]

(Beyond Pesticides, January 4, 2012) Pesticide use in California rose in 2010 after declining for four consecutive years, according to data released by the Department of Pesticide Regulation (DPR). More than 173 million pounds of pesticides were reported applied statewide, an increase of nearly 15 million pounds — or 9.5 percent — from 2009. Overall, most of the growth in pesticide use was in production agriculture, where applications increased by 12 million pounds. California’s DPR, which has the most extensive pesticide use reporting system in the United States and oversees one of the most comprehensive pesticide regulatory programs in the world, published its pesticide usage data for the state last week. Along with increases in agricultural pesticide use which reflects a 15 percent jump in acres treated with pesticides, post-harvest treatments went up by 657,000 pounds, structural pest control by 760,000 and landscape maintenance by 374,000 pounds. Reports are mandatory for agricultural and pest control business applications, while most home, industrial and institutional uses are exempt. Pesticides with the greatest increase include 1,3-dichloropropene (1,3-D). commonly known as Telone, a fumigant whose use went up by 2.4 million pounds, or 37 percent. It is used on strawberries, almonds, sweet potatoes, carrots, […]

(Beyond Pesticides, December 15, 2011) New research suggests that the recent re-emergence of bed bug infestations may originate from insecticide use in the tropics. According to the results, which were presented at the American Society of Tropical Medicine and Hygiene’s 60th annual meeting, exposure to treated bed nets and linens caused populations of bed-bugs to build resistance to those chemicals. The findings presented at the gathering showed that 90% of 66 populations sampled from 21 U.S. states were resistant to a group of insecticides, known as pyrethroids, commonly used to kill unwanted bugs and flies. Other research has already shown that an over-reliance on chemical controls over the years has helped bed bugs evolve to be resistant to these chemicals. One of the co-authors, evolutionary biologist Warren Booth, Ph.D. from North Caroline State University in Raleigh, told the BBC news that the genetic evidence he and his colleagues had collected show that the bed-bugs infecting households in the U.S. and Canada in the last decade are not domestic bed bugs, but imports. The team collected samples from across the eastern U.S. and discovered populations of bed-bugs that are genetically very diverse. “If bed-bugs emerged from local refugia, such as poultry […]

(Beyond Pesticides, December 5, 2011) On December 3, the 27th anniversary of the Bhopal pesticide plant disaster in Bhopal, India, a trial began in an international people’s court in India involving the world’s six largest pesticide companies: Monsanto, Syngenta, Bayer, BASF, Dow and Dupont. These companies, collectively known as the “Big 6,” are cited by prosecutors for their human rights violations, including internationally recognized rights to life, livelihood and health. Beyond Pesticides joined Pesticide Action Network (PAN) and others in signing a joint statement demanding that these companies be held accountable for their human rights violations, which was presented at the trial. The trial, hosted by PAN International, is facilitated by the Permanent People’s Tribunal (PTT), an international opinion tribunal independent from State authorities. The prosecution’s 230-page indictment outlines the global threats to human rights. It begins: The victims and survivors of [pesticide industry] aggression are the poor peasants, small-scale farmers, agricultural workers, rural women, children, and indigenous and agricultural communities around the world. They are at the mercy of the expanding power of the agrochemical [corporations] and are losing their control over their seeds and knowledge, and suffering debilitating physical and chronic effects due to pesticide poisoning, including coping […]

(Beyond Pesticides, November 16, 2011) On November 9, 2011, the U.S. Environmental Protection Agency (EPA) issued its cumulative risk assessment for the pyrethroid class of insecticides, concluding that these pesticides “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. The agency went as far to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. EPA issued the final pyrethins/pyrethroid cumulative risk assessment in the Federal Register and is requesting comment until January 9, 2011, including information that may be used to further refine the assessment. Pyrethroids are a widely used class of insecticides used for mosquito control and various insects in residential and agricultural settings. However pyrethroids are highly neurotoxic and have been linked to cancer, endocrine disruption, suppression of the immune system, and various reproductive effects. This class of chemicals includes permethrin, bifenthrin, resmethrin, cyfluthrin and scores of others. Read Beyond Pesticides’ factsheet “Syntethic Pyrethroids.” Once the […]

(Beyond Pesticides, November 10, 2011) Two new studies released last week add further proof that the popularity of organic food is not just an elitist trend. One report by the Organic Trade Association (OTA), The 2011 U.S. Families’ Organic Attitudes and Beliefs Study, finds that 78 percent of U.S. families purchase organic food. Another study by SCALE, Inc. finds that organic food is generally cheaper at farmers markets than at grocery stores in Southeast U.S. OTA partnered with KIWI Magazine, and polled nearly 1,300 U.S. families about their attitudes and behaviors relating to organic food. The total sample reflects the target population of U.S. households with a confidence interval of +/-3% at the 95% confidence level. This is the third year the study has been conducted. According to OTA, it contains in-depth information about organic consumers’ demographics, purchase motivation, understanding of organic, willingness to substitute when organic is not available, and attitudes about genetically modified organisms (GMOs). The other study, Is Local Food Affordable for Ordinary Folks?, compares farmers markets and supermarkets throughout 19 different communities in six Southeast states, including Virginia, Tennessee, West Virginia, Kentucky, North Carolina and South Carolina. Though the study focuses on local foods, it did […]

(Beyond Pesticides, November 9, 2011) A 2009 European Union (EU) report on pesticide residues, published yesterday by the European Food Safety Authority (EFSA), shows food on the European market is still heavily contaminated with cocktails of pesticides. The percentage of EU food in shops and markets with multiple residues remains at a high level of 25.1%, meaning only a slight improvement in the last five years of reporting. The highest reported number of pesticide chemical residues in one food item remains at 26: One sample analyzed had 26 different pesticides! Like the U.S. where consumers are exposed through food and drinking water to a variety of chemical mixtures of pesticide food residues, EU citizens also continue to be exposed to mixtures of pesticides on a daily basis. According to the report , compliance with the legal maximum residue levels (MRLs) for pesticides in food rose to 97.4 percent of the analyzed samples in 2009, up by about one percentage point from 2008, EFSA said. However, like their counterparts in the U.S., the regulatory entities EFSA and European Commission still do not protect people against the effects of mixtures. Health standards for pesticide residues do not take these effects into account. […]

(Beyond Pesticides, November 2, 2011) On Monday, a federal judge rejected a lawsuit brought by Dow AgroSciences challenging pesticide application restrictions to protect salmon and upheld the measures recommended by the National Marine Fisheries Service (NMFS) to protect endangered salmon and steelhead from three highly toxic pesticides: chlorpyrifos, diazinon, and malathion. The restrictions, recommended by NMFS’s Biological Opinion in 2008, ban the ground spraying of the three commonly used organophosphate agricultural insecticides within 500 feet of any salmon-bearing waterway, and aerial spraying within 1,000 feet. NMFS has issued four Biological Opinions, the latest on June 2011, which call for several limitations on aerial spraying and ground application of the pesticides near salmon waters, as well as buffer zones around salmon waters and ditches that drain to salmon habitat, among others. EPA was court ordered to consult with NMFS to identify measures needed to protect salmon and steelhead from the pesticides as a result of a 2002 and 2007 lawsuit. Pesticide manufacturers have been willfully ignoring and challenging NMFS’s findings. Dow AgroSciences alleged that NMFS used bad data and modeling and that the proposed buffers are far too large. Earthjustice, representing Northwest Center for Alternatives to Pesticides (NCAP), Pacific Coast Federation […]

(Beyond Pesticides, September 26, 2011) On September 23, 2011, the Centers for Disease Control and Prevention (CDC) published a study in its Morbidity and Mortality Weekly Report linking pesticides sprayed in attempts to control bed bugs to poisoning incidents and death. Because bed bugs do not transmit disease and can be controlled without pesticides, this risk is completely unnecessary. The study, “Acute Illnesses Associated with Insecticides Used to Control Bed Bugs,” utilized data from California, Florida, Michigan, North Carolina, New York, Texas, and Washington. In those seven states, over 100 poisonings, including one fatality, were associated with bed bug-related insecticide use. The CDC researchers used data from states participating in the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides program and the New York City Department of Health and Mental Hygiene (NYC DOHMH). The authors defined “acute illness” associated with an insecticide used to control bed bugs as two or more acute adverse health effects resulting from exposure to an insecticide used for bed bug control. The study reports: A total of 111 illnesses associated with bed bug–related insecticide use were identified; although 90 (81%) were low severity, one fatality occurred. Pyrethroids, pyrethrins, or both were implicated in 99 (89%) […]

(Beyond Pesticides, August 19, 2011) Children from disadvantaged backgrounds are exposed to higher levels of a slew of environmental chemicals — some currently used and some long banned — than U.S. children from other socioeconomic backgrounds, finds a study of elementary school children from urban Minneapolis, Minn. The 7- to 12-year-olds had elevated concentrations of metals, industrial chemicals and markers for pesticides and tobacco smoke in their blood and urine. The results are published in the Journal of Toxicology and Environmental Health. These findings agree with other studies reporting higher concentrations of environmental chemicals in children. What is important about this study is that these children were from low-income households where they face additional hardships from poverty. Children from disadvantaged backgrounds are more vulnerable to health issues, such as asthma and behavioral problems. Exposure to these chemicals may increase this risk even more. Compared to adults, children eat more food, breathe more air, and drink more fluid than adults per unit of body mass. This increases their intake of potentially harmful chemicals and possibly raises the risk of adverse health effects related to these compounds. In addition, children’s bodies are not fully capable of detoxifying many of these chemicals so […]

(Beyond Pesticides, August 3, 2011) Despite the continued sluggish economic recovery, U.S. retail sales of natural and organic foods and beverages rose to nearly $39 billion in 2010, according to a new report available on companiesandmarkets.com. This is an increase of 9% over the previous year’s sales of $35 billion, far outpacing growth in conventional groceries, which crept ahead less than 2%. Organic sales are projected to more than double by 2015, to exceed $78 billion. [Confused about Natural vs Organic? They are not the same. Learn more about why organic is the right choice. Read Beyond Pesticides’ factsheet “Making Sure Green Consumer Claims Are Truthful”] The report, “Natural and Organic Foods and Beverages in the U.S., 3rd Edition,” examines sales and growth potential, identifying key issues and trends that will affect the marketplace through 2015, and analyses consumer attitudes and behaviors toward natural/organic foods and beverages. Organic sales also had a great performance in 2008 with U.S. sales reaching $24.6 billion by the end of 2008, growing an impressive 17.1 percent over 2007 sales. Organic food sales accounted for approximately 3.5 percent of all food product sales in 2008. A recent poll by Thomson Reuters and National Public Radio […]

(Beyond Pesticides, May 31, 2011) A study has found that people whose workplaces were close to fields sprayed with chemicals — not just those who live nearby — are at higher risk of developing Parkinson’s disease (PD). The pesticide chemicals in question include two fungicides -maneb (in the ethylene bisdithiocarbamate (EDBC) family and ziram (in the dimethylthiocarbamate family)- and the herbicide paraquat that appear to raise the risk of developing the movement disorder. In a study published in the European Journal of Epidemiology, entitled, “Parkinson’s disease risk from ambient exposure to pesticides,” a team of researchers led by UCLA neurologist Beate Ritz, PhD found that exposures to the trio of pesticides are actually higher in workplaces located near sprayed fields than they were in residences. And the combination of exposure to all three pesticides, which act in different ways to harm brain cells involved in Parkinson’s disease, appears to be cumulative, the team led by Dr. Ritz concludes. The study found that the combined exposure to pesticides ziram, maneb and paraquat near any workplace increased the risk of Parkinson’s disease threefold, while combined exposure to ziram and paraquat alone was associated with an 80% increase in risk. The researchers estimate […]

(Beyond Pesticides, May 26, 2011) A new report by the American Academy of Pediatrics reveals that roughly one in six children in the U.S. have developmental disabilities, particularly those that are linked to environmental exposure, which showcases the need for stricter policies to reduce the use of pesticides and other toxic chemicals. The study is based on National Health Interview Surveys of children aged 3 to 17 years over the 12-year period of 1997-2008. Though the report does not indicate a specific reason for the alarming increase, the two fastest growing developmental diseases are Attention Deficit Hyperactivity Disorder (ADHD) and Autism, which are both highly linked to pesticides. Over the course of the 12-year study, ADHD rose from 5.7% to 7.6%, and the rate of autism went from 0.2% to 0.7%. This adds to the growing database of studies that show our current approach to restricting pesticide use through risk assessment-based mitigation measures is not working. The U.S. Environmental Protection Agency’s (EPA) risk assessment fails to look at chemical mixtures, synergistic effects, certain health endpoints (such as endocrine disruption), disproportionate effects to vulnerable population groups, and regular noncompliance with product label directions. Emerging science demonstrates that the amount of toxic […]

(Beyond Pesticides, May 18, 2011) Chemical-intensive agriculture groups are seeking to derail the release of an annual U.S. Department of Agriculture (USDA) report, which has been released yearly for two decades, on the amount of pesticide residue detected by the Department on nationwide samples of fresh fruits and vegetables. The Environmental Protection Agency (EPA) uses the data to monitor exposure to pesticides and enforce federal standards designed to protect infants, children and other vulnerable people. This data has been used to educate consumers about pesticide use on fruits and vegetables. For roughly two decades, USDA has tested various fruits and vegetables for pesticide residues, usually making its findings available to the public in January. More than four months into 2011 results for USDA’s 2010 tests have yet to be released. Several of the nation’s top physicians and scientists wrote to Agriculture Secretary Tom Vilsack, EPA Administrator Lisa Jackson and Food and Drug Administration (FDA) Commissioner Margaret Hamburg, urging them to no longer delay the release of the most recent test results. The letter also calls on the officials to bolster the government’s research into the adverse health effects of pesticides, particularly on children. According to the letter, “Children are uniquely […]

(Beyond Pesticides, April 22, 2011) Three independent investigations published in the journal Environmental Health Perspectives (EHP) have reached similar conclusions, associating prenatal exposure to organophosphate (OP) pesticides with IQ deficits in school-age children. The fact that three research groups reached such similar conclusions independently adds considerable support to the validity of the findings. The three studies were conducted at the School of Public Health at the University of California, Berkeley, the Mailman School of Public Health at Columbia University, and Mount Sinai School of Medicine. All three involved cohorts of women enrolled during pregnancy. The Berkeley and Mount Sinai investigators measured OP pesticide breakdown products in the pregnant women’s urine, while the Columbia investigators measured the OP pesticide chlorpyrifos in umbilical cord blood. Intelligence tests were administered to children of these mothers between ages 6 and 9 years at Mount Sinai and at age 7 years at Berkeley and Columbia. Although the study findings are not directly comparable, all three investigations found evidence linking prenatal OP pesticide exposures with adverse effects on cognitive function that continued into early childhood.”¨”¨“It is well known that findings from individual epidemiologic studies may be influenced by chance and other sources of error. This is […]

(Beyond Pesticides, March 18, 2011) As a result of recent court mandated consultations under the Endangered Species Act (ESA) concerning pacific salmon and steel head, the U.S. Environmental Protection Agency (EPA) in a letter to the National Research Council (NRC) is requesting the convening of a committee of independent experts to assist in the review of special scientific and technical issues that have arisen as the agency attempts to stem the impact of pesticides on these endangered species. Citing issues of scientific complexity and high importance, the letter authored by EPA Administrator Lisa Jackson, requests on behalf of the EPA, the Fish and Wildlife Service and the National Marine Fisheries Service (NMFS), a “concerted, closely coordinated effort” to address these issues openly and actively. NRC’s assistance is sought due to the number of complex scientific issues brought to the attention of the agencies as they complete consultations under the ESA concerning the impact of pesticides on endangered salmon and steelhead. Even though calls for EPA to holistically review pesticides have been made by scientists and the environmental community before, EPA is now seeking advice in assessing the effect of pesticides and other Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)-related actions […]

(Beyond Pesticides, March 4, 2011) California’s Department of Pesticide Regulation (DPR) has begun a program to monitor air in areas of intense agricultural production in order to assess the effects of long-term exposure to pesticides. To expand the department’s knowledge of pesticides’ potential health risks, it has set up machines to monitor air quality in three California communities: Shafter in Kern County, Salinas in Monterey County and Ripon in San Joaquin County. The program will not measure concentrations of all pesticides that are used in the state. DPR has developed a list of certain pesticides that will be monitored based on amount of use and potential health risks associated with them. In all, there will be 34 pesticides evaluated, along with breakdown products for several of them. The list includes 11 organophosphates, such as acephate, chlorpyrifos, diazinon, dichlorvos (DDVP), and malathion. Six soil fumigants will also be monitored, including methyl bromide, methyl iodide, and metam sodium. The full list is available from the DPR website. According to Mary-Ann Warmerdam, Director of DPR, “The air monitoring network is the first of its kind in the nation.” The department’s intent, she said, “is to make more accurate estimates of health risks based […]

(Beyond Pesticides, February 25, 2011) The U.S. Environmental Protection Agency (EPA) has released a new report detailing sales and usage of pesticides in the U.S. for the years 2006 and 2007 and showing a modest decrease in pesticide use. The report compiles data from EPA, the U.S. Department of Agriculture (USDA), and other sources in order to track pesticide trends and monitor usage. Previous industry use reports had been published every two years between 1994 and 2001; however, the last report was published ten years ago, in 2001, leaving a gap in the data. In one of the more promising findings, the report shows that pesticide use in the country did decrease throughout most of the last decade. Use of conventional pesticides, measured in pounds applied, decreased about 3% from 2002 to 2007 and 11% from 1997 to 2007. However, the total pounds of pesticide use decreased only by approximately 8% — from 1.2 to 1.1 billion pounds — during the years from 2000 to 2007. While any decrease in the use of toxic chemicals is a hopeful sign, this marginal reduction does not go far enough. The fact that chemicals which are known to adversely affect human health and […]

(Beyond Pesticides, February 16, 2011) Many agricultural pesticides —including some previously untested and commonly found in food— disrupt male hormones, according to new tests conducted by British scientists. Meanwhile, U.S. researchers at the National Institutes of Health have found that people who used two specific varieties of pesticide were 2.5 times as likely to develop Parkinson’s disease. Pesticides Impact Male Hormones Evidence suggests that there is widespread decline in male reproductive health and anti-androgenic pollutants, also known as endocrine disruptors, may play a significant role. Thirty out of 37 pesticides tested by the researchers at the University of London altered male hormones, including 16 that had no known hormonal activity until now. There was some previous evidence for the other 14. Most are fungicides applied to fruit and vegetable crops, including strawberries and lettuce. The study, “Widely Used Pesticides with Previously Unknown Endocrine Activity Revealed as in Vitro Anti-Androgens,” is published in Environmental Health Perspectives. The British researchers screened the chemicals using in vitro assays, which use human cells to check whether the pesticides activate or inhibit hormone receptors in cells that turn genes on and off. Scientists, however, are uncertain what actually happens in the human body at the […]
