An old exposure, PCB, shows ties to autism

Published August 29, 2016

PCB’s, or Polychlorinated biphenyls is  a group of over 200 different manufactured chemicals which stopped being used decades ago.  However, they don’t break down and widespread pollution of these chemicals means that they are still all over the environment and we continue to be exposed to them.  This week, Dr. Kristen Lyall from Drexel University showed that gestational exposure to high levels of PCB’s are linked to ASD.  This dispels the myth that scientists should narrow their scope of research to just those exposures that appeared when the rise in autism diagnoses was observed.  Hear more on the ASF podcast:
