Assessment of Toxicity of Typical Industrial Effluents

Abstract

This study aims to assess acute and chronic toxicity of some typical industrial wastewater such as textile, latex processing, paper mill, alcohol processing and leachate from municipal landfills. This result of EC50 and LC50 tests using different testing organisms showed that the toxicity of effluent is not directly proportional to COD concentration, but it depends upon BOD, ammonia, nitrite and TDS. Based on results of this study, the limited COD value of the industrial effluent quality standards for the typical industry is suggested.
