This study aims to improve knowledge on discharges of industrial effluents and their effects on receiving waters. It focuses on the analysis of physicochemical parameters (pH, temperature, COD, BOD5 and SS). Water samples were taken at three industries (cosmetics, pharmaceutical and brewing) in the city of Kinshasa. The results showed high levels for the parameters measured in the majority of the stations. In addition to pH and temperature, the contents of COD, BOD5 and SS of the effluent is much higher than the limit values set by WHO for industrial discharges to receiving waters. This could be major health risks for the population of the study area.
