P-32 POSTLABELING ANALYSIS OF AROMATIC DNA-ADDUCTS IN LIVER AND BRAINOF WILD BROOK TROUT (SALVELINUS-FONTINALIS)

Several studies have reported the absence of DNA-adducts in fish colle cted from unpolluted areas, We determined DNA-adduct levels in liver a nd brain tissue of wild brook trout (Salvelinus fontinalis) from remot e areas of Newfoundland and sub-arctic Labrador, that have no known in put of anthropogenic contamination, Varying levels of adducts were det ected in both liver and brain, at all locations. Hepatic adduct levels were generally higher than those in brain tissue, Tissue-specific dif ferences in adduct levels and the possible effects of long range trans port of air pollutants (LRTAP) are discussed,
