The priority ions that determine the high pollution of the urban atmosphere in winter are (nitrite, chloride, sodium), the sources of which are the exhaust of motor vehicles (nitrite) and the using of anti-ice reagents (chloride, sodium). The study showed an increase of the major ions in the urban snow cover (with the exception of nitrate ion) by more than two times compared with the regional and more than six times with the global natural background. To study the spatial features of the snow cover pollution interpolation surfaces of the spatial distribution of priority ions in the study area were constructed. https://jpoll.ut.ac.ir/article_89723_5e5d533b28e080f6285d09d19aa4e373.pdf
