Acute Toxicity of Chlorpyrifos on Histological Alterations in the Anomuran Crab, Emerita asiatica (H. Milne Edwards, 1837)

Abstract

Acute toxicity of Chlorpyrifos on histological alterations in the different organs like gills, hepatopancreas and ovary of anomuran crab, Emerita asiatica was studied. Though Emerita asiatica is not a commercially viable crab, but it plays a vital role in the environment to maintain a stable marine ecosystem. Several steps and precautions measures should be taken to conserve these members of the marine food chain to have a stable ecosystem and also to protect this species from extinction. Thus, it can be concluded that the use of Chlorpyrifos which has been legally banned in India is justified. It has been proved by several workers and has been conformed in present investigation that use of this Chlorpyrifos causes serious damage to the vital organ of sand crabs gill, hepatopancreas and ovary. The application of Chlorpyrifos could be reduced in the agricultural field to nearby coastal regions.

Rejuvenation of Pesticide Polluted Soil from the Isolated Microbial Flora of Agricultural Field

“…In Anomuran crab Emerita asiatica, fish and amphibians, it has produced teratogenic deformities, disturbed frog hormones, and is genotoxic to tadpoles. Pesticide microbial degradation is a hot topic right now, with several studies being conducted in this area [34,35,36,37,41,42].…”
