| Abstract |
Bioassays with two marine nematode species were used to determine the toxicity of four heavy metal compounds and three carcinogens. The test using the marine species Diplolaimelloides bruciei is more sensitive than the existing nematode test using the freshwater nematode Panagrellus redivivus for mercury chloride and 2-acetamidofluorene, but less sensitive for methylmercury chloride, phenacetin, and 4-aminobiphenyl. The Monhystera microphthalma test is less sensitive than the nematode test with P. revivus for mercury chloride, selenium oxide, and cesium chloride. The range between the concentrations at which no toxic effects are observed and the concentrations at which 100% lethality is observed is for most compounds smaller in both nematode tests with marine species than in the test using P. revivus.This suggests that the marine analogs of the P. redivivus test are less suited to detect, map, and rank the primary sites and sources of biotoxicity in an ecosystem. Further validation of the nematode tests using D. bruciei and M. microphtalma is required. |
