Nematodes are very abundant and fundamental group of soil organisms and non-parasitic species are important for soil quality. In last years nematode species were established as very suitable organisms for toxicity testing. Nematode toxicity tests have been referred as less demanding to place and time compared with other soil testing organisms and comparably sensitive. Even there is arising importance of soil contamination with persistent organic pollutants (POPs), they have never been broadly tested for soil nematode toxicity. In our study, Caenorhabditis elegans soil bioassay was used for testing toxicity of six selected POPs: four aza-PAHs (industrial by-product), toxaphene (pesticide), and short chain chlorinated paraffin (industrial product). This can help to broaden ecotoxicological profiles of these chemicals. Most of the compounds didn't show toxicity until environmentally irrelevant concentrations. Some structure dependent effects were recorded for aza-PAHs suggesting possibility of QSAR modeling for C. elegans test. Even C. elegans soil test is the most ecologically relevant, other designs (aquatic and agar tests) were used too in order to compare the results (e.g. bioavailability consequences). Toxicity of these compounds was also measured with other standard soil tests (earthworms, enchytraeids, springtails, microorganisms) and the results were compared. The sensitivity of C. elegans test was found comparable with other soil tests. This research was supported by Grant Agency of Czech Republic project 525/04/P159.
