Effluents collected from industries of different localities of NWFP we
re investigated for various parameters such as DO, BOD, total alkalini
ty, total hardness, chlorides, nitrites, sulphites and various cations
, physical parameters like temperature pH, conductivity, TDS, DS and S
S were also investigated in the same effluents. The values were compar
ed with the standard, general variation in some of the parameters were
observed. The implications of these parameters were also discussed.
