Investigation of Heavy Metal Accumulation in Unio mancus and Anodonta anatina Species Obtained from the Tigris River

mancus and Anodonta anatina species visceral mass which collected from Tigris River between 2013-2014. Forthis reason, heavy metal analysis of 90 mussels samples which taken from three stations were carry out by ICPOES.Heavy metal concentrations were measured in the Unio mancus species Zn (94.2 ppm)> Cu (31.66 ppm)>Ni (14.10 ppm)> Pb (5.72 ppm)> Co (2.51 ppm) maximum value (except Zn) was found in the first station. Thehighest value of Zn was measured in II. station as 107.86 ppm. In Anodonta anatina species the concentration ofZn> Cu> Ni> Pb> Co at I. and II. station; and Zn> Ni> Cu> Pb> Co at III. station were measured. The highestvalues of Cu (23.75 ppm), Ni (16.06 ppm), Co (3.05 ppm) and Pb (3.84 ppm) were measured in the I. station ; thehighest values of Zn (117.68 ppm) was measured in the III. station. Statistical calculations made with ANOVATukeytest and heavy metal concentrations were found significant of Cu (F=74.238; P=0.000), Ni (F=39.584;P=0.000), Co (F=13.738; P=0.000) in Unio mancus species; in Anodonta anatina species, Cu (F=35.369; P=0.000),Ni (F=20.107; P=0.000), Co (F=6.777; P=0.004), Zn (F=16.298; P=0.000) and Pb (F=16.347; P=0.000) (p <0.05).The heavy metal levels obtained from the present study, are higher than the accepted values according to TurkishFood Codex Contaminants Regulation (2011) and below the limit values determined according to EPA and FAOin bivalve.
