Abstract : Industrial practices are accountable for the discharge of inadequately processed wastewater to the terrestrial environment during its flow to the aquatic destination that threatens all types of terrestrial lives of which earthworm is an important member. Earthworms are considered as ecosystem engineers and contribute to soil fertility, development, and maintenance of soil Physico-chemical properties. In this study, earthworms were exposed to soils with different concentrations (0,25, 50, 100) in % of papermill effluent for 30 days to investigate the response of earthworms to it. It was observed that the body weight was significantly retarded whereas the rate of respiration, ammonia excretion significantly increased with an increase in the concentration of effluent in soil indicating higher metabolic maintenance in the prevailing stress conditions.
