In the region of the basin of the Bregalnica river, there are several significant emission sources of potentially toxic metals and other chemical elements in the environment, which are the following: the copper mine and flotation “Bučim” near Radoviš, the lead and zinc mines “Sasa” near Makedonska Kamenica and “Zletovo” near Probishtip (Environment statistics, 2013). The excavation of the copper minerals is carried out from an open ore pit, while in the lead-zinc mines the exploitation is underground, and the ore tailings are stored in the open air. The ore produced in the mines is processed in the flotation plants, and in the process of flotation of the relevant minerals, flotation tailings are separated and disposed on a dump site in the open. The exposure of mining and flotation tailings, as well as the exposure of the open ore pit to the air streams, leads to distribution of the finest dust. On the other hand, rain waters wash the ore tailings and make water extraction of the available metals. In this way, metals and other potentially toxic chemical elements are introduced into the soil and waters (surface and underground). At the same time, the particles from flotation and mining tailings are continually distributed by the winds. These particles, depending on the weather conditions, can be distributed in the air for longer or shorter periods of time, and thus, deposited on smaller or greater distances from the emission source. The most suitable technique for this type of study is application of relevant monitoring that will enable more lasting and efficient determination of the environment quality in the relevant investigated area. Monitoring programs have been implemented as part of numerous analytical research activities since long time ago, but in the last decades their application has been highly promoted both on regional and global level . This is due to the fact that monitoring programs do not require usage of expensive technical equipment, while analytical results reflect the situation for a longer period of time.
