[Lipid peroxidation in the lungs upon inhalation exposure to low concentrations of lead salts].
Effects of inhalation with low concentration lead salts on lipid peroxidation intensity and antioxidative system state were investigated in respiratory pulmonary branch in rats after both short-term and chronic exposures to 0.01% Pb(CH3COO)2. It was shown that the short-term toxic action had considerably affected on the antioxidant system state in lungs as a result of tissue antioxidative activity exhausting. Under the chronic lead inhalation penetrating disorders in adaptive mechanisms were found. It was reflected in lipid peroxidation product accumulation and decreased parameters of antioxidant defense, and development of energy deficiency.
