- Abstract
This paper presents the results of research on the content of heavy metals in water and fish of the River Una. During 2012 and 2013 water and fish samples were taken from four locations, and research was conducted in two seasons: autumn 2012 (I season) and spring 2013 (II season). The caught fish at all locations belonged to the species of trout (Salmo trutta). The content of Pb, Cu and Cd was determined by means of an atomic absorption spectrophotometer "Perkin Elmer" AAnalyst - 800, using a flame photometry technique. The content of Pb, Cu and Cd was below the level of maximum allowable concentrations (MAC). The research of heavy metal presence in the water of the River Una indicated the value of Pb lower than 0,0010 mg/l, Cu lower than 0.4 mg/l, and Cd lower than 0,1 mg/l. Heavy metals in fish muscle tissue were directly related to the pollution of river. Lead content in muscle tissue of fish caught in the River Una was the highest in samples which were caught at the fourth location, with 0,205 mg kg-1, while the highest copper content was identified in the same location, 0,1280 mg kg-1. The content of cadmium in fish muscle tissue samples was below 0,1 mg kg-1. The heavy metal content in the tested samples of water and fish the River Una was below the allowable limit. These results indicate that the pollution of the River Una did not reach a significant level.
