Abstract
Earthworms, as surrogate species representing soil organisms, have been routinely used for toxicity testing of different chemicals for about 10 years. A laboratory procedure using an artificial soil (“Artificial Soil Test”) and Eisenia fetida as test species has been developed. In order to validate the results of this test in respect to natural earthworm populations, and to allow the ecological significance of the laboratory data to be interpreted and extrapolated to the field, a field test was developed and performed with different pesticides. A strong correlation was found between laboratory results and effects on natural earthworm populations, indicating the validity of the “Artificial Soil Test” as an accurate assessment of hazards posed to soil fauna from use of chemicals.
