ASSESSMENT OF THE TOXICITY OF WASTE WATER FROM A TEXTILE DYEING INDUSTRY TO FRESH WATER TELEOST OREOCHROMIS MOSSAMBICUS

摘要

The present investigation was carried out to study the toxicological effects of effluents discharged from the textile-dyeing industry from Bhiwandi city, Maharashtra, India to fresh water fish Oreochromis mossambicus. Static, short-term, acute toxicity tests were performed over a period of 96 hours. The LC50 values at the end of 24, 48 72 and 96 hours were calculated. Efficiency of ETP as well as Safe concentration of the treated effluent were also calculated. The total efficiency of the treatment process was 71.42% and the safe concentration of the treated effluent is 17.85%. These data are highly useful in establishing limits of acceptability by the aquatic animals.
