Tubifex tubifex as a link in food chain transfer of hexachlorobenzene from contaminated sediment to fish
Sediments contaminated with poorly water-soluble organic chemicals pose a risk to aquatic food chains. Sediment-associated chemicals can be accumulated by endobenthic, sediment-ingesting invertebrates. Some tu...
