Abstract
We present a method using the free-living nematode Caenorhabditis eleg ans (Maupas, 1899) to assess toxicity in liquid medium and whole-sedim ent setups. Test duration is 72 h; endpoints are body length, number o f eggs inside worms, percentage of gravid worms, and number of offspri ng per worm. The effect of CdCl2 on C. elegans in liquid-phase exposur es is described as an example. Results from a field study with pollute d sediments from the River Elbe (Germany) suggest that nematodes may b e useful organisms in assessing toxicity of sediments in the whole pha se.
