The environment in areas where geological and mining activities, such as the extraction ofores containing heavy metals, take place, is heavily polluted with dusts resulting from these activities,as well as with residual waters from the mines. Depending on the meteorological conditions, as well ason the conditions under which sedimentable dusts or dusts in suspension are emitted into the air, thedistance from the main pollution source varies considerably. In order to estimate the pollution level andthe danger presented by this phenomenon, some analyses are required with regard to determining theconcentration of heavy pollutant metals in air, soil and plants samples, as well as in dusts from the air.For the precise determination of the major components, as well as the minor ones, and also the ones intraces, the analytical techniques used must have low detection limits and the lowest matrix effectspossible [1,2] . The methods that respond to these requirements are from the category of inductivelycoupled plasma atomic emission spectrometry (ICP-AES). The research was done in an area wherethere are industrial units whose main field of activity is extraction of certain ores which contain Pb, Cuand Zn as major components, as well as Cr, Mn, Ni, Co, Ag, Au, Al, and Fe as minor components or intraces. It is obvious that the presence of these metals in the air, water and soil has a negative impact onhuman health, plants and animals. This paper is a study of these aspects in an area where pollution withheavy metals reaches alarming quotas. |
