Frequent Questions

What are the health effects associated with PCBs?

PCBs build up in our bodies over time. At any given time, most of us have very low levels of PCBs - levels that are low enough not to cause harm. High levels of exposure over a long period of time, however, can be harmful to our health.

Short term exposure to large amounts of PCBs can lead to skin conditions such as acne and rashes, decreased liver function, neurological effects, and gastrointestinal effects. These types of acute toxic effects due to high levels of exposure are generally rare. Chronic exposure to lower levels of PCBs may also cause health effects. In animal studies, PCBs have been shown to cause effects on the immune, reproductive, nervous and endocrine systems. PCBs have also been shown to cause cancer in animals. Studies in humans provide supportive evidence for these health effects. Studies also show that high levels of PCBs in pregnant women can have an impact on their children's birth weight, short-term memory, and learning.
