Elemanalitikai módszerek összehasonlítása halak nehézfémtartalmának kimutathatósága szempontjából

Abstract

Heavy metal load affects our environment, increases constantly and pollutants of civilisation origin endanger the flora and the fauna. Measurement of the accumulation of various environmental pollutants including heavy metals in living organisms is increasingly utilized to monitor and detect intoxication. Heavy metals are considered to be the most dangerous inorganic micro-pollutants presently. Since these elements can be accumulated in living organisms and can be transferred by the food-chain, they may be dangerous for humans, too. In this study we determined the heavy-metal content of the scale of Aspius aspius with the help of XRF and PIXE. PIXE is a good analytical method to determine heavy metal content of low concentrations. This present study is an example for a successful multidisciplinary co-operation.
