Research and Autism News News By State Pennsylvania Autism News

August 23, 2016- "Chemicals Banned Decades Ago Linked to Increased Autism Risk Today"- A study from  A.J. Drexel Autism Institute found that children born after being exposed to the highest levels of certain compounds of chemicals, called organochlorine chemicals, during their mother’s pregnancy were roughly 80 percent more likely to be diagnosed with autism when compared to individuals with the very lowest levels of these chemicals. The team looked at a 1,144 children born in Southern California between 2000 and 2003. It was determined that two compounds in particular – PCB 138/158 and PCB 153 – were found to be significantly linked with autism risk. Children with the highest in utero levels of these two forms of PCBs were between 79 and 82 percent more likely to have an autism diagnosis, relative to those exposed to the lowest levels.
