UAB and CDC want more PCB tests for Anniston residents

Polychlorinated Biphenyl's, known as PCB, has been a major concern for Anniston residents. That's why dozens participated in a follow up health study Thursday night at Anniston hall. Researchers from UAB and the CDC answered questions.

This comes after a previous study where nearly 800 Anniston residents were tested, in which some found levels of PCB's in their blood.

That study found associations between PCB's and health measures such as blood pressure and diabetes in some of the groups. UAB professor/PhD Stephen Mennemeyer wants more tests. "We want to see how that is progressing over time, by coming back and doing a second study on the people who gave us their blood the first time," says Mennemeyer.

He says scientists are still trying to figure out how PCB's can affect the human body, and says PCB's were widely used in manufacturing years ago as a refrigerant device for protecting various types of industrial equipment.

He says the new study will focus on how Anniston residents PCB levels have changed over time, and how the changes could be affected with health outcomes.

The CDC will test their blood for dioxins, other chemicals and heavy metals that were not in the first study.

In just two weeks, UAB and the CDC will be asking people to come in to get another blood sample from them which will be used for analysis.

Mennemeyer says those results can take months.
