Recent research shows women who are exposed to solvents on the job may be more likely to have children on the spectrum, according to the National Institute for Occupational Safety and Health in Morgantown, WV. This research was completed before and during pregnancy on 750 mothers and 891 fathers that had occupational exposure and have been linked to neurological or congenital abnormalities in children. The agents can include medicines, metals, pesticides, anesthetics, asphalt, brake fluid, plastics and polymers, radiation, cleaners/disinfectants and paint chemicals and degreasers. Exposed mothers were 50% more likely to have a child on the spectrum and the solvent exposure was linked to an 85% higher autism risk. The study was not completed in a controlled environment so other factors could be involved.
