“…Potassium dichromate, however, was twice as toxic to juveniles than to adults. In field studies (Weber, 1953;Beck et al, 1987), for some According to Rudolph & Boje (1986), the data of the terrestrial and aquatic tests were used to calculate the ratios of the terrestrial to the aquatic enchytraeid LC,, values, which were compared with the ratio of the LC,, values of the Earthworm to the Duphniu Test (Table 6). Except for benomyl and pentachlorophenol the use of the same species resulted in a reduced ratio of terrestrial to aquatic LC,, values.…”

It is the purpose of this report to present a simple method for testing the toxicity of chemical substances by using enchytraeids in an aquatic environment. Up to eight different environmental chemicals were applied to various species, mainly of the genus Enchytraeus. The results were compared with those achieved for D. magna. Significant differences, however, between the LC,, values of the various enchytraeid species and the LC,, values for enchytraeids and daphnids could not be observed. For E. cJ: buchholzi the toxicological sensitivity of discrete ontogenetic stages was tested. The Aquatic Enchytraeid Test results were compared with those obtained from the Terrestrial Enchytraeid Test. It was found that in soil a chemical could be 600 times less toxic than in water, although the same species (E. albidus) was used in both environments. Even more pronounced were the discrepancies between the terrestrial and aquatic toxicities when the LC,, values for earthworms and daphnids were compared.

“…Byzova (1964) found negative e!ects of DDT in the "rst year after a single application of high doses of 30}50 kg ) ha\. HCH was repeatedly reported to have a negative e!ect on enchytraeid abundances for the "rst weeks after application (Huhta et al, 1967, for C. sphagnetorum;Weber, 1953, for enchytraeids in general) or even for a year after application (Byzova, 1964;Jans and Funke, 1989), while increased abundances are reported for the 2nd and 3rd year after application (Grigorjeva, 1953;Dormidontova, 1973;Jans and Funke, 1989). This increase might be due to an indirect e!ect of the insecticide on predators.…”
