Terelj basin area snow chemical and pollution data presented on this paper. We studied snow samples on december 2014. We chosen 5 sites in Terelj basin. Taken 3 сm thick snow samples on 0.25 m2 area. We analysis dust, mineralization, CO32-, HCO3-, SO42-, Cl-, Ca2+, Mg2+, Na+, K+ and heavy metals (Cr, Pb, Cd, Ni, Zn). Mineralization content is 10.4-144.0 g l-1, Terelj village 144.0 g l-1 and lowest content 10.4 g l-1 in davaat site, snow dust content is 19.4-553.8 g/0.25 m2, sulfate ion content is (SO42-) 6.5-41.1 mg l-1. Snow samples unpolluted by heavy metals. In generally approximate the chemical ingredients of all snow samples . Dust, mineralization and sulfate ion contents higher than base concentrations in Terelj village. The concentrations are decreasing every distance from the Terelj village. Snow ingredients lowest content in near by Davaat site.
