M. Gulfraz , Y. Mussaddeq , R. Khannum and T. Ahmad

Abstract:
The effluents samples of industries like, oil refinery, textile mills, soap and detergent, hydrogen oil and rubber industry were analyzed for pH, conductivity, hardness, alkalinity, chemical oxygen demand, total dissolved solids, nitrate, nitrite, phosphate and cations like calcium, magnesium, sodium and potassium. Similarly trace metals, were also analyzed from the effluent samples with help of the atomic absorption spectrophotometer. The results revealed that effluent samples from all industries consist of higher concentration level of metal ions as well as physico-chemical parameter as compared to the limits recommended by WHO. It was observed that in the most of cases the concentration level of metals and other parameters has crossed the limits given by NEQS.
