Earthworm as a bioindicator for soil pollution

Keshamma E

In Thailand, biological assessment of contaminated soil using an earthworm bioindicator in combination with chemical analysis should be practical and appropriate. The page includes research undertaken by several Indian scholars on many aspects of night crawler population elements and species diversity, as well as their interactions with other soil fauna and microflora. It investigates the impact of night crawler development on the physicochemical properties of soil, with a focus on India and other tropical countries. There is a wealth of opportunity in the subject of night crawler evaluation to explain the significance of these crucial soil macrofauna from the biological to the atomic level. Worms are a common organic organism used to investigate soil toxicity. They have been widely used to investigate the environmental impact of heavy metal contamination. Our understanding of pesticides' damaging effects on these animals is quite limited. Lumbricus terrestris was used as a bioindicator to investigate the effect of human activities on soil quality. Pb in the worm P. corethrurus may be utilised as an integrated evaluation to screen for significant metal traffic pollution since it has a high BAF and strongly correlates with traffic volume. Metallic mercury's interaction with natural acids present in residue and dull water frameworks is a fundamental pathway for Hg bioavailability. Drilling mud in soil is toxic and can cause serious damage to earthworm tissues and organs. Earthworms' clitellum, heart, and blood vessels were investigated for histological abnormalities. We discovered mild to severe necrosis and a brownish deposit, which worsened as the drilling mud concentration increased. Organic pesticides are the most efficient means of preserving soil fertility.
