Abstract :With increasing industrialization, environmental pollution has become a threat to human health.  The heavy metal pollution, especially from industrial waste water, is the best example of this. Chromium holds a special position among living organisms because on its species it can be either essential or toxic. Cr insert ignore into journalissuearticles values(VI); even at very low concentrations is harmful and carcinogenic, while Crinsert ignore into journalissuearticles values(III); is a necessary microelement for cellular metabolism. Therefore, it is very important to determine the chromium metal found in the wastewater of leather, paint and iron - steel industries. Four main creeks discharges located in the important industrial area in Kocaeli Province are made to the Gulf of İzmit. In this study, Cr insert ignore into journalissuearticles values(VI); was measured by the spectrophotometer S.M.3500-Cr B. Calorimetric Method sampled from four main streams Saz, Dil, Narca insert ignore into journalissuearticles values(Bağ); and Ambar insert ignore into journalissuearticles values(Ulupınar); Creeks samples and the results were found to be <0.02 mg / L. With these values it is observed that there is a visible improvement in the pollution of the creeks.
