What are the health effects of PCBs?
While there have been many laboratory experiments and other studies which have tried to determine the full health effects of PCBs on humans, none has been definitive. As a result, even expert opinion varies significantly on this subject. Scientists generally agree it is unlikely that serious injury would result from short-term low-level exposure to PCBs. However, most are concerned about possible adverse health effects of long-term exposure to even low concentrations of these substances. PCBs can enter the body through skin contact, by the inhalation of vapours or by ingestion of food containing PCB residues.
