| Abstract | ||
| This study was conducted in Ranya Lakelet/Dukan, the study started at the end December of 2014 to early April of 2015, heavy metal concentration in water, sediment and fish organs (skin, gills, intestine, liver and muscle.). The experiment was conducted in the laboratory of Chemistry Department, Faculty of Science at University of Raparin, Sulaimani, Kurdistan Region - Iraq. The trials for the sampling species lasted for three months (January, February and March). Sixty eight common carp taken as a sample, then divided into four length groups (20-30(19 fishes); 31-40(29 fishes); 41-50(11 fishes); 51> cm (9 fishes)). Heavy metals contents analysed in water, sediment and fish organs, including Cadmium (Cd), Zinc (Zn), Nickel (Ni), Chromium (Cr), Copper (Cu) and Lead (Pb). The study results showed that the mean concentrations heavy metals (Cd, Zn, Ni, Cr, Cu and Pb) were below detection limit (1µg/L) except Zn, which it was 8.18 µg/L in filtered water. Whereas, the mean concentrations of heavy metals (Cd, Zn, Ni, Cr, Cu and Pb) in sediments were 6.90 µg/L, 146.29 µg/L, 151.46 µg/L, 161.74 µg/L, 38.86 µg/L and 92.49 µg/L, respectively. The higher concentrations of heavy metal (Cd, Zn, Ni, Cr, Cu and Pb) in different organs were 0.69 µg/L, 6352.84 µg/L, 16.52 µg/L, 9.25 µg/L, 42.18 µg/L, and 11.44 µg/L, respectively. While the lower concentration of heavy metal (Cd, Zn, Ni, Cr, Cu and Pb) in different organs were BDL, 208.53 µg/L, 2.93 µg/L, 2.93 µg/L, 20.13 µg/L, BDL, respectively. This study showed that storing of heavy metals occurs by this order; Zn>Cu>Ni>Cr>Cd>Pb. Although the trend of heavy metals concentrations according to length groups generally represented as follows; group4> group3> group2> group1. | ||
