TABLE 2.
A summary of the results of the lab tests on the toxicities of contaminant mixtures with other pollutants in addition to PAHs is organized here.

The contaminant mixtures are either derived from sediments collected from contaminated sites or from anthropogenic chemical products. This non-exhaustive list provides a collection of common end points used to study chemical toxicity and some of the effects of the contaminants that may manifest in a less controlled setting.
