Accumulation of Metals and Metalloids in Aegean Chub, Inhabiting in Two Middle Sized Streams in Southwest Anatolia

Abstract

Essential and non-essential total eleven metals and metalloids (Al, B, Cr, Co, Cd, Cu, Fe, Pb, Mn, Ni and Zn) concentrations were determined by ICP-AES in muscle of Squalius fellowesii (Gunther, 1868), between November of 2013 and June of 2014, on chosen four stations on Tersakan and Saricay streams. Average concentrations (mu g g(-1) wet weight) in Tersakan: Al (60.81 +/- 58.51), B (27.13 +/- 12.42), Co (0.07 +/- 0.05), Cd (0.01 +/- 0.02), Cu (1.44 +/- 0.51), Cr (0.75 +/- 0.54), Fe (33.49 +/- 30.69), Mn (2.19 +/- 1.35), Ni (0.98 +/- 1.27), Zn (20.71 +/- 20.16) and in Saricay: Al (33.82 +/- 37.19), B(8.15 +/- 8.90), Co (0.04 +/- 0.035), Cd (0.01 +/- 0.01), Cu (0.90 +/- 0.44), Cr (0.40 +/- 0.27), Fe (12.97 +/- 8.17), Mn (3.75 +/- 2.045), Ni (0.54 +/- 0.82), Zn (19.05 +/- 10.65) were found. Lead (Pb) was found below detection limits in all stations or seasons while Al accumulation was found highest. The effects of water quality parameters on essential and non-essential metal-metalloid accumulations in fish tissue were indicated by PCA and Co-inertia analyses. Concentrations of observed non-essential metals did not exceed the consumption limits. The evaluation of the data obtained from the study, in Tersakan and Saricay streams, reveal that the ecological balance can be changed in a negative way in case of continuation of the pollution of these two streams.
