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 (VI) even at very low concentrations is
harmful and carcinogenic, while Cr(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 (VI) was measured by the spectrophotometer S.M.3500-Cr
B. Calorimetric Method sampled from four main streams Saz, Dil, Narca (Bağ) and
Ambar (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.

Keywords

Creek, Water pollution, Heavy metal, Chromium (VI)
