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