Researchers have noted learning and memory problems in some children who were exposed to PCBs before birth. PCB exposure can cause liver damage. In general, chemicals affect the same organ systems in all people who are exposed. However, the seriousness of the effects may vary from person to person. Each person's reaction depends on several things, including individual health, heredity, previous exposure to chemicals including medicines, and personal habits such as smoking or drinking.
Doctors can use blood tests to evaluate exposure to PCBs.
This type of blood test is expensive and not always locally available. Testing can also detect PCBs in human fat or breast milk. Most testing of this type has been done for research purposes. Liver function tests may be helpful in determining damage from exposure. Seek medical advice if you have any symptoms that you think may be related to exposure.
