  • Title: Accumulation of heavy metals with water quality parameters in Kızılırmak River Basin (Delice River) in Turkey.

    Journal: Environ Monit Assess; 2011 Feb; 173(1-4):387-95. PubMed ID: 20204694.
    Abstract:
    Kızılırmak River has been used as Ankara's drinking water source for approximately 1.5 years. Therefore, this region's water, sediment, and fish samples are measured for detecting the heavy metals. This is important for the current situation as well as the future in terms of potential impact. The amount of heavy metals in drinking water should be within the limited values; otherwise, the accumulation of heavy metals will cause many problems to living organisms. Especially high levels of arsenic, cadmium, nickel, mercury, etc. are very dangerous to freshwater ecosystems as for human if the water is being use as drinking water. In this study, water, sediment samples, muscle, and gills of three fish species (Capoeta tinca, Capoeta capoeta, Leuciscus cephalus) were analyzed for the presence of heavy metals such as (Al, Fe, As, Cd, Ni, Mn, Se, Si) to determine present accumulation levels and possible toxic effect. The accumulation pattern of heavy metals in the water, sediment, and fish tissue follows the sequence: Si>Fe>Al>Mn>As>Ni>Se>Cd, Fe>Al>Mn>Ni>As>Se>Cd, and Fe>Al>Mn>As>Ni>Si>Cd. In addition, the detected concentrations of heavy metals in the Kızılırmak and Delice Rivers are compared with other heavy metal studies in the other main rivers and lakes in Turkey.
