Biological Effects of Atmospheres Contaminated by Auto Exhaust

Abstract

Irradiated auto exhaust increases the susceptibility to pulmonary infection and chronic disease during the latter half of the animal''s lifetime, and markedly decreases in mouse fertility and decreases the survival rate of infant mice. Both raw and irradiated auto exhause cause a stress and adaptation response in mice as measured via spontaneous activity, increase bone lead concentrations, and increase the amount of nonfunctional or abnormal lung tissue. No experimental atmospheric effects were observed concerning: mortality; histopathology; growth-bodyweight; immunology; hematology restricted to erythrocyte count, erythrocyte cell size distribution, hematocrit or hemoglobin concentration; blood O2 and CO2 values; oxygen consumption; or polmonary function in relation to permanent impairment.
