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.
Animal model: Sprague-Dawley rat Tissues sampled/endpoints measured: Residue levels (trans-nonachlor, oxychlordane and trans-chlordane) in adipose, liver and kidneys; clinical changes indicative of liver and kidney function; molecular changes indicative of microsomal enzyme induction and cellular proliferation; biomarkers of cellular proliferation in multiple tissues, including mammary glands, liver and kidneys; total body fat levels in male and female rats.
