Abstract

Damage to DNA caused by exposure of L929 fibroblasts to ozone was reflected by the generation of strand breaks, DNA inter-strand cross-links and DNA-protein cross-links. Addition of propan-2-ol, a hydroxyl radical scavenger, did not affect the formation of strand breaks. In model experiments it appeared that both purines and pyrimidines were involved in DNA inter-strand and DNA-protein cross-links.
