The effluents from about half of Scotland's population and industry drain to the Clyde Estuary and Firth, where they cause a number of problems of contamination and pollution. This paper outlines historical aspects of urban growth, effluent production and disposal, pollution and pollution control. The sources, nature, quantities and main effects of effluents discharged are described, as is recent national and international legislation intended to prevent or control pollution. Reference is also made to the determination of licence conditions for effluent discharges by means of the Environmental Quality Objective/Environmental Quality Standard approach.
