Abstract: Heavy metals are one of the major pollutants. The main sources of pollution are industry, transport, the use of pesticides and mineral fertilizers in agriculture, the military industry, etc. Pollution is mostly around businesses, highways and treated terrains and they are polymetallic, mostly from Cu, Pb, Zn, Cd, Hg, As and others. In the current paper the main heavy metals for Bulgaria for the different sources of pollution are presented. An analysis of data for problem areas is made, according to sources of pollution. An analysis of the impact of pollutants on the environment is also conducted.
