Abstract
Chlorinated phenolic derivatives are important chemical constituents that are present in pulp and paper mill effluents. Subadult rainbow trout (Salmo gairdneri) were exposed to six dichloroto terachloroguaiacols, two chlorinated vanillins and trichlorosyringol through waterborne and dietary exposure. Equilibrium concentrations were attained within 2 d in waterborne exposed fish, and bioconcentration factor (BCF) values ranged from 1 to 270 among the guaiacols, less than 5 for the chlorovanillins and 125 for trichlorosyringol. Dietary exposure indicated these chemicals are poorly absorbed and have half‐lives of less than several days. The kinetics of these chemicals are consistent with residue levels reported in fish collected from waters receiving mill effluents where waterborne uptake appears to be the primary mode for accumulation.Keywords
