Suitability of carboxylated porphyrin profiles as a biochemical indicator in whitefish (Coregonus clupeaformis) exposed to bleached kraft pulp mill effluent

Abstract The hepatic carboxylated porphyrin profile was studied in whitefish exposed to bleached kraft pulp mill effluent (BKME). The distribution of the porphyrins was different between the samples from the BKME and the reference site, and fish exposed to BKME contained higher amounts of highly carboxylated porphyrins (HOP). The ratios of HCP to protoporphyrin, and coproporphyrin to protoporphyrin, were also significantly different between …
