Analysis of atmospheric deposition in the territory of the Republic of North Ossetia-Alania by biomonitoring data

Attention to the tourism potential of Republic North Ossetia-Alania is increasing with attendant need monitor and control atmospheric air pollution. Aim. The assessment possibility using mosses as biomonitors for determining content heavy metals other trace elements in atmosphere territory Ossetia-Alania. Material Methods. green Hylocomium splendens Pleurosium schreberi were used bioindicators. Multi-element chemical analysis was carried out X-ray fluorescence morphology composition dust fallouts on moss surfaces studied a scanning electron microscope equipped an energy-dispersive spectrometer. Results. maximum concentration Pb, Zn, Cr, As, Sn, Sb, Ba, Cd, Cu, Ti, Ce, Fe, Sr observed areas high aerotechnogenic load. biomonitor area Fiagdonna tailing dump indicates that recultivation measures had been effective. Toxic fall surface form fine particles large 1 micron pose danger human health. Conclusions. abnormally Sr, Ba registered zone influence mining processing enterprises (in Unal tailings dump) metallurgical industries Vladikavkaz (JSC Electrozinc JSC Pobedit. base source toxic determined be accumulate mosses, thus confirming efficiency their use monitoring. near village Dur can recommended background ecological geochemical research.
