A comparison of time-related changes in trans-nonachlor, oxychlordane and trans-chlordane residues in rat tissues and the relationship between tissue residue levels, functional changes and gender.

Updated 2015-10-05

Short term: To compare changes in trans-nonachlor, oxychlordane and trans-chlordane residues over time in fat and other tissues (using the rat model), and to relate fat and tissue residue levels to clinical changes in male and female rats. Long term: To provide current information on the toxicity of chlordane metabolites and constituents, including trans-nonachlor and oxychlordane.

This is not a National Implementation Plan (NIP) project
