摘要: Abstract Uptake of pulp and paper mill-derived pollutants by benthic invertebrates from sediment in Southern Lake Saimaa, eastern Finland, was studied. Two groups (Diptera Oligochaeta) were analyzed for their concentrations resin acids (RAs), chlorophenolics (CPs) β -sitosterol. The samples collected 1 3 km downstream the mill. In laboratory experiments Chironomus plumosus (a dipteran) Lumbriculus variegatus (oligochaete) exposed 14 d to sediments same locations. RAs, CPs -sitosterol higher areas mill than those upstream reference area both feral laboratory-exposed animals. Examination possible conjugation contaminants revealed hydrolyzable fractions RAs Diptera, C. L. . results indicate bioavailability uptake fauna when mill-contaminated sediment.
