Assessment of Boron in Water, Sediment and Fish Tissues of Porsuk Stream, Turkey

In this study, boron concentrations has been estimated between 2010 and 2011 in water, sediment and some cyprinid species from thirteen stations (five of them were on the Porsuk Dam Lake) of Porsuk Stream, a tributary of Sakarya River. According to our data, in general boron accumulations in Porsuk Stream follows as sediment > fish tissues > water, respectively. The highest boron concentrations of abiotic components detected in Porsuk Stream were recorded as 2.37 mg L-1 in station 9 for water and as 71.8 mg kg(-1) in station 3 for sediment in summer season. Also the highest boron concentrations of biotic components detected in Porsuk Stream was recorded as 24.8 mg kg(-1) in gill tissues of Carassius gibelio collected from station 9.
