ABSTRACT
Earthworm, Eudrilus eugeniae, exposed to different concentrations of dump-site soil and petroleum effluents exhibited different morbidity and mortality responses. Lake sediments caused varied fluctuations in weight over a 20 day exposure period. Colour changes and mortality up to 15% were observed in earthworms cultured in 100% lake sediment, while weight loss, coiling and sluggish movement were observed in 50% lake water. The effects of 100% dump-site soils were more pronounced as 40% death, swelling, body lesions, stiffening, coiling and low reproduction were recorded. Earthworms were useful as an organism in testing the toxicity of dump-site soils and effluent from a petroleum industry. Dump-site soils and soils polluted with petroleum effluent reduced populations of earthworms and this could subsequently affect other components of the ecosystems associated with earthworm activities.
