Impact/Purpose:

This is a statistical model for predicting mercury concentrations in fish tissue . The model identfies important variables contributing to the variation in mercury concentrations in fish.

Description:

The potential adverse effects of chemical contaminants in fish is an ongoing EPA concern that is directly related to Clean Water Act responsibilities to ensure that waters of the United States are fishable and swimmable. Mercury is a fish tissue contaminant that can bioaccumulate through the food chain, resulting in body burdens that are higher than the baseline exposure concentrations. EPA has compiled available mercury fish tissue data, and completed an empirical study of the fish parameters and location parameters contained in the data base with additional source parameters and environmental parameters that have been linked to mercury accumulation in fish.
