Abstract: Now a days scientific press pays increasing attention to the risk of environmental pollution from anthropogenic sources. Heavy metal load of the 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.
