Abstract
Cladophora species accumulate high nutrient levels in the areas contaminated by domestic and industrial wastes. This species are generally considered as the best bioindicator of aquatic eco - system contaminatio n by heavy metals. The object of this study was to investigate to cadmium, cobalt, chrome, copper, lead, nickel, iron and zinc concentration of Cladophora crispata sam - ples taken from stations on Melet River provided drinkin g water in Ordu. For this aim, t he con - centrations of heavy metals in Cladophora crispata sample were collected from four different stations, were determined using ICP -MS and AAS methods. All heavy metals were statistically analysed and evaluated. When the lead ( Pb; 844. 9 μg/g) values of the Cladophora crispata samples collected from the second stations near copper, lead and zinc mining industry were compared with the data from other stations (ANOVA), the differences were meaningful and significant.
