The characteristics of river water before mixing of industrial effluents are within the range of NEQS of Pakistan. The quality of river water, however, was deteriorated after receix ing enormous amount of organic pollutants. in terms of BOD5, from vegetable oil ::.hee mills and pulp and paper industrial units. in particular. Need of establishing admissible limits for different industrial effluents having specific dilution rates that might be accommodated by the river water without harming its natural biota is indicated.
