Resumo: | 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 &lt;i&gt;Diplolaimelloides bruciei&lt;/i&gt; is more sensitive than the existing nematode test using the freshwater nematode &lt;i&gt;Panagrellus redivivus&lt;/i&gt; for mercury chloride and 2-acetamidofluorene, but less sensitive for methylmercury chloride, phenacetin, and 4-aminobiphenyl. The &lt;i&gt;Monhystera microphthalma&lt;/i&gt; test is less sensitive than the nematode test with &lt;i&gt;P. revivus&lt;/i&gt; 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 &lt;i&gt;P. revivus&lt;/i&gt;.This suggests that the marine analogs of the &lt;i&gt;P. redivivus&lt;/i&gt; 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 &lt;i&gt;D. bruciei&lt;/i&gt; and &lt;i&gt;M. microphtalma&lt;/i&gt; is required.
