Abstract
Distribution of heavy metals and trace elements from anthropogenic origin in water, sediments, aquatic plants and different tissues of fish from Snagov Lake, Romania. has been investigated. The concentration of Cu, Zn, Cd, Ti, V, Cr, Mo, Co and Ni, was collected from three sites of the lake, during spring time from water, sediments, Ceratophyllum demersum, Phragmites australis reed, and Scardinius Erytrophtalmus fish. The fish samples were taken from gills, muscles, scales and bones. The ecological risk index has been assesed and bio-concentration factor, (BCF), of metals in anatomical tissues of studied fishes to be used as a diagnostic tool for lake pollution Experiments have shown that Ti and Zn had the highest concentration in water, sediments, aquatic plants and fish samples. Also, the metals bio-concentration is increased in branchiae and scales, compared with muscles and bones.
