About 300 different chemicals, I beleive. An antibody test is only a
reasonable method to determine PCB's if you already do those tests, and
you don't need quantitative or precise data. Chemical or
chromatographic methods are usually better.

There are still deposits of PCB's, such as at the bottom of the Hudson
River, and so still people trying to get bacteria to eat them.
Technical writing, literature search, and data analysis at the interface
of chemistry and biology.
