text: The purpose of the study was to evaluate the potential toxicity of inhaled zinc oxide aerosol following sub-chronic exposures in rats (5 days per week for 13 consecutive weeks), to define the concentration response, to identify and characterize effects on target organs, to determine the tissue distribution of zinc as a function of concentration and continued exposure, to determine the reversibility of exposure-related toxic effects, to evaluate specific toxic potential on the immune, hematopoietic, and reproductive systems and to select concentrations for a possible subsequent chronic toxicity and carcinogenicity study in Fischer 344 Rats.
