Integrated Pest Management in Schools by Charles Fox and Amanda Windom
New research conducted by the California Department of Health suggests a link between autism and in utero exposure to endosulfan and dicofol, organochlorine pesticides that are banned in many countries, but still used in the United States. The study, published by Environmental Health Perspectives, is the first to explore the connection between maternal residential exposure to organochlorine pesticides at different concentrations during key periods of gestation and risk of ASD (autism spectrum disorder) in children. ASD risk increased with poundage of organochlorine applied and decreased with distance from field sites. The study concludes that risk for ASD was consistently associated with residential proximity to organochlorine pesticide applications during critical periods of embryonic development. The study also states that the possibility of a connection requires further study.
Many pesticides, rodenticides and other toxins applied in public spaces operate on the nervous system of the targeted pest. The application tends to be around base boards/floors where younger children spend much more time than adults or older children making them more vulnerable to the effects of these neurotoxins Over time these chemicals can have particularly negative effects for students with special needs who often have immune system deficits or nervous systems that have already been injured in some way. The effects of neurotoxins in schools, in my opinion, is factor that is rarely considered when IEP teams convene to consider behavioral or learning issues. Only the most obvious situations, like overgrowth of toxic molds, are ever even considered as a problem typically because the effects are widespread and not subtle.
According to Science Week pesticide poisoning is a commonly under diagnosed illness in the U.S. and can resemble acute upper respiratory tract illness, conjunctivitis, and gastrointestinal illness. Studies have also shown a 50-70% increased risk for Parkinson's Disease with exposure to herbicides, insecticides, and pesticides. Exposure to chemicals, including pesticides can cause multiple chemical sensitivity (MCS), a disorder which is triggered by exposure to chemicals in the environment. Use of chemicals in schools can prevent children who have MCS from having access to a mainstream education. For example, two children in Maryland were forced to attend a home school program when their school was being reroofed and sprayed with pesticide.
