From Environmental Health News:

PFCs are associated with attention and behavior problems in children, suggest a pair of studies published online in June. These studies are some of the first to explore the relationship between PFC compounds and behavior problems, specifically attention-deficit/hyperactivity disorder (ADHD) and impulsive behavior.

In one study, preteen children were more impulsive when they had higher blood levels of six PFC compounds. The other reports that children with higher blood levels of one type of PFC – PFHxS – have an increased chance of ADHD.

A variety of products use PFCs during manufacturing, and the compounds are present in just about everyone. Together, the reports suggest further research is needed to discern human health effects of PFC exposure.
