Abstract

Earthworms are soil bioindicators, indicating soil stress conditions. Agrochemicals are key stress factors in agricultural soils. The ecotoxicity research employed profenofos, a pesticide widely used in Tamilnadu's delta areas. In this way, Profenofos dermal toxicity (LC50) on earthworms (Eisenia fetida) was evaluated and its impact on earthworm tissues was anticipated using histology research. Profenofos was found to be “Super toxic”, with an LC50 of 0.0088g/cm2. The earthworm epidermis, peritoneal epithelium, Chloragogen cells, longitudinal muscles, etc. were severely damaged histologically. The study indicated that Profenofos is very hazardous to earthworms and that additional research on acute and chronic toxicity is required.
