    Autism Spectrum Disorder (ASD) Associated with Pesticide ExposureRecent Studies eventually underline the chemical/neurodevelopmental disorder connection towards industrial chemicals and neurobehavioral disorders – further connection to keynotes seen in Autism Spectrum Disorder or ASD and ADHD symptomology.

    To eliminate pests, most of agricultural pesticides are neurotoxic. Although safety is highly considered, like farmers to wear protective gear, levels of chemicals on possibly affected individuals nearby cannot be said and known.

    What about the effects on the developing fetus?

    UC Davis researchers in tandem with MIND Institute found a connection between pregnant women living in close proximity of California pesticide applications and later diagnoses of ASD and other developmental delays.

    The large, multi-site California-based study, published in Environmental Health Perspectives, examined associations between specific classes of pesticides like organophosphates, pyrethroids and carbamates that were applied during the study participants' pregnancies and later diagnoses of autism and developmental delay in their offspring. The associations were stronger when the exposures occurred during the second and third trimesters of the women's pregnancies.

    Researchers focused on areas with the heaviest pesticide applications – Sacramento Valley, Central Valley and the greater San Francisco Bay Area. They examined commercial pesticide application using the California Pesticide Use Report and linked the data to the residential addresses of approximately 1,000 participants in the Northern California-based Childhood Risk of Autism from Genetics and …

    According to Hertz-Picciotto, in early stage of pregnancy, the brain is developing synapses. It is the space between neurons, where electrical impulses are changed into neurotransmitting chemicals that move from one neuron to another to pass messages along. This formation is very important and these pesticides may be where they function and could affect neurotransmission.

    She emphasized how tough to lessen the risk and hopes to have further discussion of ASD risk and chemical exposures at both the societal and individual level, specifically pre-natal nutrition. With this as her most concern, she personally does not desire for her family to reside where pesticides are commonly used and applied.
