Abstract – The article presents the results of bioassay analysis of potassium dichromate as a reference chemical in Eisenia foetida test model applied for ecotoxicity assessment of industrial wastes. Test organism response range was determined to be as follows LC₅₀ = 0.272-0.297 g/kg potassium dichromate under acute experimental conditions within intralaboratory testing.

Keywords: bioassay, Eisenia foetida, ecotoxicity, industrial wastes, reference chemical.
