Dynamics change of chemical compounds in the composition of the dust aerosol on period of dust storms in Tajikistan

摘要

This contribution presents the composition of dust aerosol collected in dust storms in the territory of the weather station Ayvaj southern Tajikistan, during the years 2007-2015. High concentrations of the compounds SiO_(2)(54.23%), CaO (11.25%) and Al_(2)O_(3)(10.16%) were found, which is characteristic for dust. The statistical characteristics of measured compounds is determined and the correlation coefficients between certain compounds are calculated. A significant high correlation is observed between SiO_(2)and Na_(2)O (r=0.98), between Fe_(2)O_(3)and SO_(3)(r=0.89), between Fe_(2)O_(3)and Al_(2)O_(3)as well as between K_(2)O and MgO (r=0.89).
