(Beyond Pesticides, November 20, 2013) Illinois public health officials say that more than 200 Illinois schools and day care centers have failed to comply with the most basic of the state’s pest management regulations, and for the first time could face fines if they do not comply. According to the Illinois Department of Public Health (IDPH), the state’s IPM regulations, including the requirements for reporting how pests are managed, are designed to protect children in day care centers and schools from unnecessary applications of pesticides. Last Friday, the Illinois Department of Public Health announced that it is ramping up its efforts to educate day care centers and schools about the rules aimed at reducing and managing pests in light of widespread non-compliance with pest management regulations in public schools and day care centers. State law requires public schools and licensed day care centers to file an Integrated Pest Management (IPM) form with the department to document how school officials plan to implement IPM. The state’s Structural Pest Control Act (Act), [225 ILCS 235] requires public schools and licensed day care centers to, when economically feasible, develop and implement an IPM program and resubmit their plans every 5 years. Additionally, all […]

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

(Beyond Pesticides, October 3, 2013) According to new research, residents are more highly exposed to organophosphate and pyrethroid pesticides in New York City (NYC) than in the U.S. overall.  Researchers from the city’s Department of Health and Mental Hygiene reviewed the 2004 NYC Health and Nutrition Examination Survey (NYC HANES) to compare its pesticide exposure patterns in an urban environment with the nation as a whole. The NYC HANES includes a biomonitoring component to evaluate pesticide exposures by measuring concentrations of organophosphate and pyrethroid metabolites in urine. According to the authors, the findings underscore the importance of considering pest and pesticide burdens on cities, where a dense population results in a single exposure source affecting many people at the same time when regulating pesticide use. Organophosphate metabolites were measured in the urine of 882 New Yorkers, while 1,452 residents were tested for pyrethroid metabolites. As the researchers explain, the building density and disrepair in parts of NYC likely increased the chances of a pest infestation, which in turn can lead to the reliance on indoor pesticide use. By the 1980’s, organophosphates were the most common class of insecticides in the U.S., and were used indoors until the early 2000’s when […]

(Beyond Pesticides, March 6, 2012) New research conducted in New Bedford, Massachusetts suggests that organochlorine chemicals, which were first linked to learning problems in children more than two decades ago, may play a role in attention-deficit hyperactivity disorder (ADHD), especially in boys. Previous research has reported associations between organochlorines and ADHD-related behaviors, but this research found sex-specific effects in children born to mothers who lived near the contaminated harbor and dumpsites in low-income communities. This study adds to a growing body of literature associating learning disorders with prenatal chemical exposures. According to the study, Neuropsychological Measures of Attention and Impulse Control among 8-Year-Old Children Exposed Prenatally to Organochlorines, boys who were exposed to higher levels of the organochlorines -polychlorinated biphenyls (PCBs) and DDE (a metabolite of DDT)- in the womb scored lower on focus and concentration tests, which indicates they are more likely to have attention problems often related to ADHD. In the study, umbilical cord blood was collected from 788 newborns born between 1993 and 1998 from four towns near New Bedford Harbor, Mass., to see what they were exposed to in the womb. Roughly eight years after they were born, almost 600 of these children underwent two tests. […]

(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 10, 2011) In three new studies published in the May issue of the journal Health Affairs (Vol. 30, No. 5), Mount Sinai School of Medicine researchers reveal the staggering economic impact of toxic chemicals and air pollutants in the environment, and propose new legislation to mandate testing of new chemicals and also those already on the market. The studies, “Environmental Disease in Kids Cost $76.6 Billion in 2008,” “Children’s Vulnerability to Toxic Chemicals,” and “Pollutants and Respiratory Illness in Infants,” are available on the Health Affairs website. Leonardo Trasande, MD, Associate Professor of Preventive Medicine and Pediatrics at Mount Sinai School of Medicine, analyzed the costs of conditions — including lead poisoning, childhood cancer, asthma, autism, and attention deficit hyperactivity disorder (ADHD) — associated with exposure to toxic chemicals. Dr. Trasande and his team calculated the annual cost for direct medical care and the indirect costs, such as parents’ lost work days, and lost economic productivity caring for their children, of these diseases in children. The researchers found the annual cost in the United States to be an estimated $76.6 billion, representing 3.5 percent of all U.S. health care costs in 2008. The breakdown includes: lead poisoning […]

(Beyond Pesticides, August 25, 2010) Exposure to pesticides while in the womb may increase the odds that a child will have attention deficit hyperactivity disorder (ADHD), according to researchers at the University of California-Berkeley School of Public Health. Maternal metabolites of organophosphate pesticides have previously been associated with neurobehavioral deficits in children. The California researchers are studying the impact of environmental exposures on the health of women and children who live in the Salinas Valley, an agricultural region with heavy pesticide use. They tested the urine of pregnant women for pesticide residue, and then tested the behavior of their children at ages 3 ½ and 5. The 5-year-olds who had been exposed to organophosphate pesticides while in the womb have more problems with attention and behavior than did children who were not exposed. Results are published online in the study entitled, “Organophosphate Pesticide Exposure and Attention in Young Mexican-American Children,” in the journal, Environmental Health and Perspectives. Previous studies have shown that exposure to some organophosphate compounds cause hyperactivity and cognitive deficits in animals. One study published in Pediatrics earlier this year found that exposure to organophosphates in developing children might have effects on neural systems and could contribute to […]

(Beyond Pesticides, May 18, 2010) A team of scientists from the University of Montreal and Harvard University have discovered that exposure to organophosphate pesticides is associated with increased risk of Attention-Deficit Hyperactivity Disorder (ADHD) in children. Using data from the National Health and Nutrition Examination Survey, the study focused on 1,139 children from the general U.S. population and measured pesticide breakdown product levels in their urine. The authors conclude that exposure to organophosphate (OP) pesticides, at levels common among U.S. children, may contribute to a diagnosis of ADHD. “Previous studies have shown that exposure to some organophosphate compounds cause hyperactivity and cognitive deficits in animals,” says lead author Maryse F. Bouchard, a professor at the University of Montreal Department of Environmental and Occupational Health and scientist at the Sainte-Justine Hospital Research Center. “Our study found that exposure to organophosphates in developing children might have effects on neural systems and could contribute to ADHD behaviors, such as inattention, hyperactivity, and impulsivity.” Marc Weisskopf, PhD, ScD, another study author told Reuters, “What this paper specifically highlights is that this may be true even at low concentrations.” For children with a 10-fold increase in the concentration of the most common dialkyl phosphate metabolites […]
