A pilot study of heavy metal concentration in various environments and fishes in the Upper Sakarya River Basin, Turkey

Abstract

In this study, concentration of lead, cadmium, copper, cobalt, nickel, and manganese were measured in water, sediment, and fish (Cyprinus carpio and Barbus plebejus) samples at the upper Sakarya river basin in Sept. 1995–1996 period. Also, physical parameters of selected stations in the Sakarya river were measured. Mean concentrations of lead, cadmium, copper, nickel, and manganese differed between water, sediment, and fish samples by seasons. Mean concentrations of lead, cadmium, and cobalt increased in sediment samples in October and August. In water samples only cadmium and cobalt increased in October whereas lead and copper increased in August. Also, high levels of manganese concentrations were detected in water and sediment samples and fish tissue during the study. ©1999 John Wiley & Sons, Inc. Environ Toxicol 14: 367–373, 1999

Heavy metal in tissues of Tor grypus from Atatürk Dam Lake, Euphrates River-Turkey

“…Similarly, the mean values of gill Cu and Zn are lower than those determined in samples collected in the Tigris River (Gümgüm et al 1994) and B. capito pectoralis (Heckel, 1843) in the Keban Dam Lake (Sarieyüpoglu & Say 1991). The values of Cu, Co and Mn in fish samples obtained in the present study were found to be similar to those reported for Barbus plebejus (Bonaparte, 1832) in the Sakarya River (Barlas 1999).…”

Assessment of pollution in the West Black Sea Coast of Turkey using biomarker responses in fish

“…It carries many pollutants to the Black Sea from inner regions of Turkey (Tuncer et 108 al., 1998; Barlas, 1999). Industrial areas found in Düzce and Adapazarı drain their 109 discharges into Efteni Lake.…”

The study of heavy metal pollution and accumulation in water, sediment, and fish tissue in Kızılırmak River Basin in Turkey

“…Generally, heavy metals create toxic effects by forming complexes with organic compounds. The solubility of the metals primarily, depends on the pH, dissolved oxygen, and hardness (Barlas 1999). Increase in pH generally decreases the solubility of toxic heavy metals (Hellawel 1988).…”
