two species of amphipod, Pontoporeia hoyi (Landrum, 1989), and Diporeia spp.
(Landrum et al., 1992; Harkey et al., 1994b) in dosed sediments aged less than 1 w.
Naphthalene tissue residues of freshwater oligochaete Lumbriculus variegatus
generally peaked by the starting and tended to decline to the end of the exposure
(Brunson et al., 1998). In the same way, accumulation of naphthalene from sediment
by marine worm Arenicola marina was rapid and almost complete depuration of the
accumulated naphthalene was observed after 24 h (Lyes, 1979). And also,
Lumbriculus variegates accumulated pyrene and benzo (a) pyrene in dosed-sediment
and these compounds were found to be depurated within 72 h in clean sediment
(Leppanen and Kukkonen, 2000b).
