(Beyond Pesticides, January 23, 2009) A study by researchers at the UC Davis M.I.N.D. Institute has found that the seven- to eight-fold increase in the number children born in California with autism since 1990, a trend which shows no sign of abating, cannot be explained by either changes in how the condition is diagnosed or counted, and that environmental factors must be looked at more closely. Published in the January 2009 issue of the journal Epidemiology, the study is entitled “The Rise in Autism and the Role of Age at Diagnosis.” Results from the study suggest that research should shift from genetics to the host of chemicals and infectious microbes in the environment that are likely at the root of changes in the neurodevelopment of California’s children, including pesticides and household chemicals. “It’s time to start looking for the environmental culprits responsible for the remarkable increase in the rate of autism in California,” said UC Davis M.I.N.D. Institute researcher Irva Hertz-Picciotto, PhD, a professor of environmental and occupational health and epidemiology and an internationally respected autism researcher. Dr. Hertz-Picciotto said that many researchers, state officials and advocacy organizations have viewed the rise in autism’s incidence in California with skepticism. The […]

(Beyond Pesticides, January 21, 2009) Without federal legislation mandating schools adopt safer pest management strategies, around 75% of U.S. schools continue to use hazardous pesticides. As a result, a diverse group of school pest management stakeholders have developed a new document, Pest Management Strategic Plan for IPM in Schools, that they hope will help reinvigorate the adoption of Integrated Pest Management (IPM) programs, aiming for full implementation in all U.S. schools by 2015. The school IPM PSMP document is an in-depth look at the current status of school IPM, specific pest management strategies for schools to use, and actions and timelines for a coordinated effort to getting all schools adopt an IPM program. The strategic plan hinges on garnering leaders in school administration, school health, parents, teachers, custodians, food service staff, state agricultural extension staff, regulators, architects, IPM professionals and other interested individuals to help increase awareness and generate a commitment to school IPM. A group of more than 30 professionals, including Beyond Pesticides staff, have been involved in the development process for the school IPM PSMP, in cooperation with the U.S. Department of Agriculture (USDA) IPM Program, the four USDA Regional IPM Centers, and the US Environmental Protection Agency […]

(Beyond Pesticides, December 17, 2008) Researchers in Spain conducted the first worldwide study of pesticides in fruit-based soft drinks and found high levels of pesticides in drinks from some countries, especially the United Kingdom and Spain. Drinks sampled from the United States, however, had relatively low levels. The study, to be published in the December 15th issue of the American Chemical Society’s journal, Analytical Chemistry, and entitled, “Determination of Pesticide Residues in Fruit-Based Soft Drinks,” screened for approximately 100 pesticides in fruit-based soft drinks purchased from 15 different countries from companies with brands distributed worldwide and found relatively large concentration levels of pesticides in most of the samples analyzed. The detected pesticides included carbendazim, thiabendazole, imazalil and its main degradate, prochloraz and its main degradate, malathion, and iprodione. These pesticides are normally applied to crops as post harvest treatments. The researchers found relatively large concentrations of pesticides, in the micrograms per liter (ug/l) range, in most of the samples analyzed. Samples from Spain and the U. K. had the highest levels of pesticides, while samples from the U. S. and Russia were among the lowest. Many international brands are imported into the United States. While pesticide regulations in the United […]

(Beyond Pesticides, December 4, 2008) According to a new study published in the December issue of the journal Archives of Pediatrics & Adolescent Medicine, children of U.S. farm workers are three times more likely than other children to have no health insurance coverage. This problem is worst among migrant and immigrant families. The situation limits farm worker children’s access to health care, elevating the adverse impact of pesticide exposure and poisoning. The study, entitled, “Determinants of Health Insurance Status for Children of Latino Immigrant and Other US Farm Workers,” documents the findings of the U.S. Department of Labor’s National Agricultural Workers Survey which was administered to a total of 3136 parents with children younger than 18 years. The objective of the study was to characterize the health insurance status of farm workers’ children, which is currently an understudied topic. Researchers found that thirty-two percent of all farm worker parents, including 45% of migrant-worker parents, reported that their children were uninsured. Farm workers’ children are uninsured at roughly 3 times the rate of all other children and almost twice the rate of those at or near the federal poverty level. Children were more likely to be uninsured if their parents were […]

(Beyond Pesticides, December 1, 2008) A new study by researchers at the University of California Los Angeles finds chronic exposure to commonly used dithiocarbamate fungicides, such as ziram, contribute to the development of Parkinson’s disease. According to the study, Ziram Causes Dopaminergic Cell Damage by Inhibiting E1 Ligase of the Proteasome, published in the Journal of Biological Chemistry, researchers screened several pesticides for their ability to interfere with the ubiquitin-proteasome system (UPS). Impaired UPS activity is reported in Parkinson’s disease patients’ brains. The researchers then focused on dithiocarbamate fungicides because they were found to be one of the most potent UPS inhibitors and are commonly used. The researchers discovered the mechanisms by which the UPS is impaired, showing that ziram and structurally related dithiocarbamates inhibit E1 ligase (a protein activating enzyme). Ziram is also found to increase alpha-synuclein (a protein expressed in the central nervous system) levels and selectively damages dopaminergic neurons in vitro. The study also cites unpublished data from a population-based study in central California that is determining pesticide exposure using state application registry, finding that individuals living within 500 meters of where ziram is applied are at three times the increased risk of developing Parkinson’s compared to […]

(Beyond Pesticides, November 14, 2008) A preliminary review of pesticide poisoning complaint records kept at the Oregon State Department of Agriculture and Department of Human Services reveals that children participating in school activities have been exposed to pesticides dozens of times in the past ten years. The review of the State’s pesticide complaint records was conducted by Oregon Toxics Alliance, a statewide organization working to protect human and environmental health. The report uses data from the Oregon Department of Agriculture, the Oregon Department of Human Services and the Oregon Department of Forestry to develop a better understanding of how and why Oregon school children are being exposed to pesticides during their school activities. The report was presented to Governor Kulongoski’s Natural Resource Advisor Michael Carrier and State School Superintendent Susan Castillo on November 10, as well as other officials and state agencies. The data collected for the report reveals an on-going pattern of pesticide exposure to school children in classrooms, on playgrounds, on ball fields and at school bus stops. 56 separate cases of Oregon school children experiencing pesticide exposure were reported in Oregon since 1990 – 43 of them filed in the past ten years. In 14 cases, the […]

(Beyond Pesticides, November 3, 2008) A new study, Pyrethroid pesticides and their metabolites in vacuum cleaner dust collected from homes and day-care centers (doi:10.1016/j.envres.2008.07.022), by the U.S. Environmental Protection Agency’s (EPA) National Exposure Research Laboratory finds concentrations of 13 synthetic pyrethroids and their degradates in indoor dust collected from homes and childcare centers in North Carolina and Ohio. The study results show the extent to which hazardous pesticides are present in indoor environments and threaten the public’s health, especially the health of children. With 85 vacuum cleaner bags analyzed, permethrin was present in all 85 dust samples, at least one pyrethroid pesticide was found in 69 samples and phenothrin was found in 36 samples. According to the study findings published in the November issue of the journal Environmental Research, the median concentration of permethrin in the samples is 1454ng/g of dust. Excluding permethrin, pyrethroid conectrations are less than or equal to 100ng/g of dust. The majority of the metabolites are present in more than half of the dust samples. This is not the first time researchers have found pesticides in dust in homes. A study published in the International Journal of Hygiene and Environmental Health (208: 193-199) also found that […]

(Beyond Pesticides, September 29, 2008) A new study by Pesticide Action Network North America (PANNA) confirms that school children in Florida continue to breathe air contaminated by hazardous pesticides. Air monitoring near South Woods Elementary School in Hastings detected four agricultural chemicals in the air, often at levels that pose unacceptable risks to children. The report mirrors the results of a similar study released in April 2007, confirming the existence of an ongoing problem of pesticide contamination that is more extensive than previously documented. The new test results show that in October, November and December 2007 the air in Hastings was contaminated with the pesticides endosulfan, diazinon https://www.beyondpesticides.org/gateway/pesticide/diazinon.htm, trifluralin and chlorothalonil. Of these, two are neurotoxins, two are suspected carcinogens, and three are or will soon be banned in Europe. Endosulfan, the pesticide of greatest concern, was found in 87% of the samples, and, on several days, exceeded levels of concern. The air monitoring was conducted by concerned area residents using a “Drift Catcher” device, a simple air sampling system that sucks air into tubes, where the pesticides are absorbed and captured. The tubes are then sent to a laboratory, where the chemicals can be identified and the concentrations measured. […]

(Beyond Pesticides, September 25, 2008) Pesticides used as lice treatments can not only have extremely harmful effects on children, they are also not as effective as non- chemical treatments such as utilizing directed hot air, according to researchers. Back-to-school season often coincides with lice outbreaks, and parents should be aware of the risks involved in using lice “shampoos” that contain pesticides and informed of the viability of non-toxic alternatives. Many of the recent headlines regarding lice in schools include reference to “super lice,” which are difficult to eliminate. These lice have developed resistance to the chemicals commonly used to treat them, such as lindane, malathion and permethrin, and therefore these treatments are increasingly ineffective. Insects frequently develop resistance to pesticides, a fact that emphasizes the importance of strategies both in agriculture and public health that focus on preventing pest outbreaks and dealing with outbreaks in ways that will not lead to resistance. One such method for eliminating head lice that will not lead to resistant strains of lice is the use of hot air, which desiccates the insects and eggs, thus killing them. Researchers testing six methods of hot air application found that hot air outperforms insecticidal shampoos in killing […]

(Beyond Pesticides, September 22, 2008) A study published in the September issue of Environmental Health Perspectives finds that low-dose, short-term exposure to esfenvalerate, a synthetic pyrethroid pesticide, delays the onset of puberty in rats at doses two times lower than U.S. EPA’s stated no observable effect level (NOEL) of 2.0 mg/kg/day. Synthetic pyrethroids are used for everything from lawn care and household insecticides, to mosquito control and agriculture. There are currently 348 pesticide products registered by the U.S. EPA. The researchers conclude: “Although the exact mechanism of action is unknown at this time, we observed the effects at dosage levels below the NOEL established through chronic dietary exposure studies in rats. The U.S. EPA (1998) http://www.epa.gov/fedrgstr/EPA-PEST/1998/April/Day-29/p11372.htm stated that ”˜There is no evidence of additional sensitivity to young rats or rabbits following pre- or postnatal exposure to esfenvalerate.’ The present study shows that immature female rats exposed to 1.0 mg/kg/day are sensitive to this pesticide, as evidenced by their delay in the onset of puberty. Delayed pubertal onset in humans has been associated with low bone mass density (Ho and Kung 2005), and estrogen is necessary for bone mineral acquisition in both girls and boys (Yilmaz et al. 2005). Importantly, a […]

(Beyond Pesticides, September 17, 2008) A new study has found a link between total chemical contamination in the bodies of pregnant women and the risk of cryptorchidism in their male babies. Mothers whose babies were born with the defect had the highest concentrations of persistent organic pollutants (POPs), mostly organochlorines like PCB and DDE, in their breast milk. The study, entiltled “Cryptorchidism at birth in Nice area (France) is associated with higher prenatal exposure to PCBs and DDE, as assessed by colostrum concentrations,” and published in the journal Human Reproduction, compared prebirth exposure to chemicals, as measured through their mother’s milk, and the risk of undescended testicles or cryptorchidism, during a three-year period. 164 mother/infant pairs were used and within 3-5 days of delivery, the researchers collected samples of colostrums, or “first milk” from the mother. Colostrum is a form of breast milk that is produced late in pregnancy and immediately after birth before the more creamy milk comes in. It is used as a proxy for what was circulating in the mother’s body and in her fetus during pregnancy. The colostrum was analyzed for three different chemical pollutants including seven polychlorinated biphenyls (PCBs), dichloro-diphenyl-trichloro-ethylene (DDE) and dibutyl phthalate (DBP). […]

(Beyond Pesticides, September 16, 2008) Responding to grassroots pressure highlighting the impact of pests and pesticides on public health, the Boston Public Housing Authority (BHA) is promoting integrated pest management (IPM) through its Healthy Pest Free Housing Initiative Project (HPFHI) in the city’s public housing facilities. The program, which was launched after the Committee for Boston Public Housing, a tenant rights group, began looking into the connection between respiratory health, asthma and housing conditions in 1995, is now proving successful. “The project’s goal is to provide intensive in-home and community-based education designed to change individual and community practices regarding pest control and the use of pesticides,” explains John Kane, IPM coordinator and planner for the Boston Housing Authority (BHA). Mr. Kane says that there has been up to a 75 percent reduction in work orders dealing with pests and a huge increase in the quality of life for the residents. Over 1,000 BHA households in eight developments have received in-home and community-based support and education to encourage integrated pest management practices that focus on prevention and use “least toxic” pesticides only as a last resort. BHA hopes to make the project sustainable and expand their efforts into additional developments. “People […]

(Beyond Pesticides, June 11, 2008) The House of Representatives has passed legislation that will provide nearly $7 billion in grants to help K-12 schools go green. Entitled, “21st Century Green High-Performing Public School Facilities Act” (H.R. 3021), the bill, sponsored by Rep. Ben Chandler (D-KY), will help schools to become more energy efficient and healthier. There is a special emphasis on low-income schools where children are most at risk from unhealthy facilities and on schools that still suffer from the aftermath of hurricane Katrina. The legislation passed by the House on June 4, will allow the Secretary of Education to distribute funds to K-12 school districts according to a need-based formula, to make them more energy efficient, healthy, and high performing. Funding can also be used for asbestos removal services, energy efficiency improvements, lead abatements, and technology upgrades. The bill will also help school districts, which are struggling to make essential improvements, to create better school facilities and save significant amounts of energy and help to reduce greenhouse gases. Thirty-nine percent of greenhouse gas emissions come from buildings, and each green and energy efficient school will lead to annual emission reductions of 585,000 pounds of carbon dioxide (CO2) — the […]

(Beyond Pesticides, May 13, 2008) Citing concerns over the impact of pesticides on health and the environment, the Voorhees, NJ Township Committee approved Resolution 126-08, Township of Voorhees Pesticide Reduction Policy, on April 28, 2008 to stop hazardous pesticide use. The New Jersey Township has adopted Integrated Pest Management (IPM) as the pest control policy and strategy to be used in the maintenance of the township’s public properties and buildings, and township parks are pesticide free posted with “Pesticide Free Zone” ladybug signs.The National Center for Environmental Health Strategies, which proposed the resolution, will be working with the township’s pest control contractor on an IPM plan for township buildings to continue to eliminate or significantly reduce the use of hazardous pesticides. The guidance will in part be based on the New Jersey School IPM Law (S. 137, adopted September 26, 2002), which requires that after non-chemical means of pest control have been considered and exhausted and conventional pesticide use is deemed necessary, preference be given to using a pesticide that is classified “low impact.” Low impact pesticides according to the New Jersey School IPM Law include a first category of pesticides or substances that are U.S. EPA exempt from regulation […]

(Beyond Pesticides, April 1, 2008) On March 27, many distinguished environmental health and justice advocates in addition to political leaders gathered in Los Angeles, CA to express their gratitude & praised the efforts of the Los Angeles Unified School District, (2nd largest in the nation) for working cooperatively for a decade with California Safe Schools (CSS), a children’s environmental health organization in creating the most protective pesticide policy for schools in the country. California Safe Schools (CSS) was formed by Robina Suwol in 1998, following an incident with her then 6-year-old son Nicholas, a student at Sherman Oaks Elementary School. Unaware students were present, a school gardener in a hazardous materials suit sprayed the herbicide Princep, creating a cloud of pesticide mist students were forced to walk through in order to reach their classrooms. Later, Nicholas, whose asthma had previously been under control, experienced a life-threatening asthma attack. Ms. Suwol’s initial research on a web site sponsored by Cornell University revealed that a single exposure to Princep could be very dangerous to children, and may cause tremors, convulsions & paralysis, among other symptoms. Further investigation revealed that many chemical pesticides commonly used in schools carry significant risks to growing children […]

(Beyond Pesticides, March 11, 2008) A Decade of Children’s Health Research: Highlights from EPA’s Science to Achieve Results Program, a ten-year Environmental Protection Agency (EPA) study released March 10, 2008, summarizes important research findings found from $127 million invested in research grants on children’s environmental health in response to an executive order issued in 1997. Executive Order 13045, Protection of Children From Environmental Health Risks and Safety Risks, requires federal agencies to place a high priority on assessing risks to children. EPA, through its Science to Achieve Results (STAR) program, issued more than 60 research grants in response to this order, which in turn, produced more than 1000 scientific journal articles. “Understanding potential environmental health risks to children is important to EPA,” said George Gray, assistant administrator of EPA’s Office of Research and Development. “This research will help us assess and address environmental factors that may affect some of the most vulnerable members of our society.” The report summarizes research from the STAR children’s health program over the past 10 years, highlighting scientific findings in epidemiology, exposure science, genetics, community-based participatory research, interventions, statistics and methods. Some of the major findings of this research include: People metabolize pesticides differently based […]

(Beyond Pesticides, March 10, 2008) Head lice affect an estimated 12 million people in the U.S. each year, and are rapidly becoming resistant to over-the-counter and prescription medications. Researchers at the University of Massachusetts Amherst have found that ivermectin, a compound produced by soil-dwelling bacteria, was 100 percent effective in killing head lice resistant to many standard treatments. Results were published in the January 2008 edition of the Journal of Medical Entomology. Although ivermectin is not well-absorbed through the skin, some public health advocates are concerned about its use on humans for lice and scabies. The National Pediculosis Association (NPA), a non profit agency, directs parents, health care professionals and child care providers to safer head lice control options via a standardized prevention approach focusing on routine screening, early detection and thorough combing and manual removal of lice and nits. NPA promotes this as a rational strategy over chasing lice with pesticides that offer more risk than benefit and have a well-documented history of lice resistance and failure.Most products used to treat head lice contain the insecticide pyrethrum, or its synthetic cousin permethrin, as the active ingredient. Over the past two decades, resistance to these chemicals has become a serious […]

(Beyond Pesticides, March 3, 2008) In a five-year study of the Chesapeake Bay, the nation’s largest estuary, the U.S. Geological Survey (USGS) found that, “Synthetic organic pesticides and their degradation products have been widely detected at low levels in the watershed, including emerging contaminants such as pharmaceuticals and hormones.“ The report finds that concentrations of DDT, while still present, have declined since the 1970s when it was phased out. The findings are contained in a report entitled Synthesis of U.S. Geological Survey Science for the Chesapeake Bay Ecosystem and Implications for Environmental Management. The study is a part of the Chesapeake Bay Program (CBP), which is a multi-agency partnership working to restore the Bay ecosystem. According to the report introduction, “In 2005, which represented the mid-point of the Chesapeake 2000 agreement, there was growing concern at all levels of government and by the public that ecological conditions in the Bay and its watershed had not significantly improved. The slow rate of improvement, coupled with the projected human-population increase in the Bay watershed, implied that many desired ecological conditions will not be achieved by 2010. The Government Accountability Office (2005) recommended that the CBP complete efforts for an integrated assessment approach […]

(Beyond Pesticides, February 25, 2008) After two years of residents calling on local authorities for greater protection from drifting airborne pesticides, the Tulare County Agricultural Commissioner has adopted new pesticide buffer zone rules, or “permit conditions,” that prohibits aerial applications of restricted use pesticides within one-quarter mile of schools in session or due to be in session within 24 hours, occupied farm labor camps and residential areas. The Allensworth School Board, the Cutler-Orosi School Board and over 1,750 organizations and individuals endorsed the call for buffer zones in Tulare County. Community members launched efforts to establish buffer zones because of the serious health risks posed by pesticide exposure, ranging from short-term effects such as dizziness, vomiting and rashes to long-term effects including asthma, cancer, birth defects, damage to the developing child and neurological harm. Community efforts included conducting surveys documenting the general public’s exposure to pesticides, sampling for pesticides in the air and in residents’ bodies, and presenting local authorities with a petition endorsing the establishment of buffer zones around sensitive sites such as schools. According to the Mercury News, “An Associated Press investigation found that 590 people in California were sickened by pesticides at schools from 1996 to 2005, […]

(Beyond Pesticides, February 13, 2008) The publication of a federal study undertaken by the Centers for Disease and Control (CDC) has been blocked for more than seven months because it contains “alarming information” of evidence of elevated infant mortality and cancer rates in the region surrounding the Great Lakes.The report entitled, Public Health Implications of Hazardous Substances in the Twenty-Six U.S. Great Lakes Areas of Concern, was commissioned by the International Joint Commission (IJC), an independent organization that advises the U.S. and Canadian governments on the use and quality of boundary waters between the two countries, and compiled by the CDC’s Agency for Toxic Substances and Disease Registry (ATSDR). The report outlines the “areas of concern” in which more than nine million people in major metropolitan areas as Chicago, Cleveland, Detroit, and Milwaukee, face higher health risks from exposure to dioxin, PCBs, pesticides, lead, mercury, or six other hazardous pollutants.Contributors to the report include senior experts from the Environmental Protection Agency, CDC, universities, as well as federal and state researchers. These experts have been reviewing data since 2004 and have found low birth weights, elevated rates of infant mortality and premature births, and elevated death rates from breast cancer, colon […]

(Beyond Pesticides, February 11, 2008) Growing out of concern from pesticides drifting onto school grounds, the Hawaii Senate has begun looking at adopting legislation that would better protect students and staff from nearby pesticide applications.The bill, SB 3170, will establish a 1,500 foot no-spray buffer zone for all backpack applications and a half-mile buffer zone for all aerial applications around all elementary schools. It will also require a 72-hour prior written notification to all schools in the immediate area of a pesticide application as well as a one-week prior notification of all commercial use of pesticides within a five-mile radius of any school or educational institution property to the Department of Education (DOE). DOE will then notify the appropriate schools within 72-hours of the proposed application. The bill’s author, Senate Majority Leader Gary Hooser, stated on his website, “A pesticide is poison. It is designed to kill. No child should be subjected to it, especially in a learning environment. To allow it doesn’t even make sense.” Many of those that spoke at the public hearing on the bill on February 4th had been impacted by the type applications the bill is trying to prevent. Kauai’s Garden Island Newspaper states that […]

(Beyond Pesticides, January 31, 2008) A study to be published in the February 2008 issue of Environmental Health Perspectives finds that children who eat a conventional diet of food produced with chemical-intensive practices carry residues of organophosate pesticides that are reduced or eliminated when they switch to an organic diet. The study is entitled “Dietary Intake and Its Contribution to Longitudinal Organophosphorus Pesticide Exposure in Urban/Suburban Children” (Chensheng Lu, Dana B. Barr, Melanie A. Pearson, and Lance A. Waller) and includes authors from Rollins School of Public Health, Emory University, and the National Center for Environmental Health, Centers for Disease Control and Prevention.According to the authors, “The objective of this article is to present the data of assessing young urban/suburban children’s longitudinal exposure to OP [organophosphate] pesticides in a group [of] young children participating in the Children Pesticide Exposure Study (CPES). The results from this study identify not only the predominant source of OP pesticide exposure but also the profile of exposures in children that are vital in formulating the strategies, both from the regulatory policy and personal behavior change perspectives, in reducing children’s exposures to OP pesticides.” The study design included 23 children, male and female, from the Seattle […]
