Assessment of Cd, Hg, Pb, Cu and Zn Amounts in Muscles of Cyprinus Carpio from Karasu Stream, Sinop

Abstract

Heavy metal contaminations in aquatic habitats effect negatively on the organisms that depend on the water. In this work heavy metal levels in edible tissues of Cyprinus carpio from Karasu Stream in Sinop in summer, autumn and winter were determined by Inductively Coupled Plasma Mass Spectrometer. The accumulation pattern in the work is in the order of Zn>Cu>Pb>Cd> Hg. The amounts of Hg, Cd, Pb, Cu and Zn in carps were 0.022-0.036, 0.031-0.045, 0.22-0.29, 1.32-1.61 and 8.4-12.3 mg kg-1 wet wt., respectively. Concentrations of heavy metals in C. carpio were all below the TFC and EC guidelines. Total target hazard quotient (TTHQ) was 0.10722 and below 1 which showed that consumption of carp from the Karasu Stream has no health threats by now as the heavy metals investigated was concerned.

“…RfD m is the oral reference dose (mg/kg bw /day) (Table 2). Given the challenges in setting a reliable threshold for lead (Pb) according to the USEPA, this study relied on the RfD Pb (reference dose for lead) proposed by previous research as a suitable alternative [60][61][62][63]. RfDm is the oral reference dose (mg/kgbw/day) (Table 2).…”
