Description Studies on acute toxicity of textile effluents, collected from various Textile Dye Industries from Erode industrial area, Tamil Nadu, have been carried out. The juveniles of pink prawns (Metapanaeus monoceros) were exposed to a mixture of effluent samples in five different concentrations prepared in seawater, using static acute toxicity test protocol to obtain the 96-h LC50. The five different dilution factors of effluents made up with seawater were 200, 100, 50, 33.33, and 20 respectively. The environmental factors such as salinity, temperature, dissolved oxygen and pH were monitored from different effluent dilutions every 24 hours during the experiment till 96 hours. Each tank of different effluent dilution contained 10 test organisms in 3L of effluent content besides a control tank. The results showed that the 96-h LC50 of Erode effluent samples for prawns is 29 ppm, the upper limit is 41 ppm and the lower limit is 17 ppm. Maximum mortalities occurred at a dilution factor 20 i.e. concentration of 50 ppm. This indicated a greater toxicity of these tested textile effluents from Erode (with a Dilution Factor of 20) as compared to the effluents tested earlier by other workers from different dye industries in Erode area (with a Dilution Factor of 5)
