Morphological, Biochemical and Molecular Responses of Earthworms to Environmental Contaminants

Abstract:

Earthworms are keystone soil organisms and serve as sensitive bio-indicators due to their direct interaction with pollutants. Exposure to heavy metals induces oxidative stress, alters antioxidant enzyme activity and damages gut tissues. Herbicides like diuron trigger ROS accumulation, histopathological damage in intestinal epithelium and DNA fragmentation. Antibiotics such as oxytetracycline impair antioxidant defences, modify metabolic pathways, and reduce coelomocyte viability. Micro-plastics, both biodegradable and non-biodegradable, disrupt biomass, gut micro-biota, and enzymatic activity in different earthworm species. Exposure to petroleum hydrocarbons affects glycolysis, TCA cycle, and amino acid metabolism, demonstrating metabolic disruption. Combined pollutant exposures, such as neonicotinoids with heavy metals, intensify oxidative damage, AChE inhibition, and genotoxicity.


Keywords: Keystone Soil Organisms, Bio-Indicators, Herbicides, Histopathological
