  1. Dna damages caused by so2 and lead acetate were studied with the single cell microgel electrophoresis technique ( or comet assay ) in order to confirm the damaging degree of lead ( as an important component of atmosphere particle matter ) on dna from male mice exposed to so2. the migrating distances of dna of brain, lung, spleen and kidney cells of mice increased significantly, compared to the control group under conditions of single and combined poisoning of so2 ( 42mg / m3 ) and lead acetate ( 0. 2 % ), and lead could strengthen dna damage degree by so2 in nuclear dna of brain, kidney, spleen cells. damaging degree of so2 on nuclear dna of lung cell of mice was more severe than that of lead
