摘要：In this paper an attempt has been made to analyse the behaviour of Lyari River contaminated wastewater to main sea. Main focus is on the sate of water ways and physical, chemical and metallic parameters for effluents. Empirical analysis is done for the proper conclusion and implications. Lyari River is the natural stream having substantial catchments area. It has become a natural drainage channel for almost a quarter of the existing built up area of the city. Lyari River becomes a putrid and toxic channel when it passes through the metropolitan area of Karachi. It carries the water which is purely a combination of domestic sewage and industrial effluents. These effluents have very high load of pollutants and pathogenic bacteria. Where as the industrial wastes are the main source of toxic metal, pesticides and lubricating oils. These effluents contaminate the marine aquatic environment and coastal area. New models are given for analyses
