Effluent samples from electroplating industry were collected and brought to the laboratory immediately for the analysis of physico-chemical characteristics. The analyzed parameters were compared with the Central Pollution Control Board (CPCB) standards. Static acute toxicity test was performed for a period of 96 hours using different concentrations of effluent of electroplating industry with the objective of evaluating the acute toxicity to the fresh water fish, Cyprinus carpio. The 24, 48, 72 and 96 hr LC50 values were 0.203, 0.158, 0.132, and 0.128% respectively. The need of toxicity evaluation assay for confirming the quality of effluent from the point of effective environmental safe limits and to ensure integrity of aquatic environment is stressed.
