TI  - Effects of heavy metal pollution on hepatosomatic ındex and vital organ histology in Alburnus mossulensis from Karasu River
AB  - In this study, histological effects of water pollution to freshwater cyprinid, Alburnus mossulensis, was investigated. Water,sediment, and fish samples were taken from four stations in Karasu River (Erzurum, Turkey) between June and September in 2015–2016. In water and sediment samples, the concentrations of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, and Pb were detected.Histopathological changes in gill, liver, and kidney tissues were determined by degree of tissue change (DTC), and hepatosomatic index(HSI) was calculated. The mean concentrations of heavy metals in water and sediment samples were lower at station 4. The trend of somemetal contents found in the fish was in increasing order of Zn < Cu < Cr < Pb. The observations on histopathology included cellulardegeneration, congestion, dilatation, vacuolization, edema, vasodilatation, hyperplasia, hypertrophy, infiltration, melanomacrophageaggregates, glomerulopathy, fibrosis, and necrosis. It was observed that the DTC and HSI values in fish varied significantly from stationto station. The results showed that the higher severity of histopathological alterations in the fish tissues was strongly correlated withagricultural and domestic activities in the area.
