Abstract

Little information is available about the toxicity of inorganic selenium forms in soil animals. Therefore, the effects of selenate and selenite on the mortality and reproduction of Enchytraeus albidus were examined in standard laboratory tests with chronic exposure. Total and available amount of selenate and selenite were tested in a calcareous loamy chernozem soil. The LC 50 of selenate was 5.69 (2.7-8.12) mg kg-1 dry wt. for total Se and 4.74 (2.14-6.98) mg kg-1 dry wt. for available Se. Selenite LC50 was as high as 22.5 (19.6-25.7) mg kg-1 dry wt. for total Se and 8.10 (6.8-9.6) mg kg-1 dry wt. for available Se. The EC50 of selenate was 0.41 (0.35-0.48) mg kg-1 dry wt. for total Se and 0.28 (0.24-0.34) mg kg-1 dry wt. for available Se. Selenite EC50 was as high as 7.3 (6.2-8.5) mg kg-1 dry wt. for total Se and 2.46 (2.05-2.91) mg kg-1 dry wt. for available Se. The response in reproduction was more sensitive to Se toxicity than the response in mortality. Selenate proved to be more toxic than selenite. Available data show that E. albidus may function as a biological indicator for some inorganic selenium forms in the soil.
