Assessment of heavy metals pollution of Snagov Lake, Romania

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 fromgills, muscles, scales and bones. The ecological risk indexhas been assesed andbio-concentration factor, (BCF), of metals in anatomical tissues of studied fishesto be used as a diagnostic tool for lake pollutionExperiments 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
