Heavy Metals in the Soils of Georgia - Bok av Tengiz Urushadze, Yuri Vodyanitskii, m.fl. - Häftad
Soil degradation processes are very sensitive to mountainous countries like Georgia, where erosion processes, contamination of soils with heavy metals and radiation are the biggest concerns. Contamination with heavy metals is resulted from two sources: transport and industry. When sources of soil pollution are mining industries, in contaminated rivers concentrations of Cu, Cd, Mn, Ni, Pb and Zn exceed the background values. The problem is that there are no maximum permissible concentrations defined..
