Lead is the only body of unwanted trace elements, it is a stable non-degradable pollutants, long-term accumulation in the environment, but also accumulate in human and animal tissues. The main toxic effects of lead are lead to anemia, neurological disorders and kidney damage. The main sources of lead emissions in waste batteries, smelting, metal, machinery, coatings and plating industries. Lead is one of the indicators of the total implementation of emission control.
