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 SiO2 (54.23%), CaO (11.25%) and Al2O3 (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 SiO2 and Na2O (r=0.98), between Fe2O3 and SO3 (r=0.89), between Fe2O3 and Al2O3 as well as between K2O and MgO (r=0.89).
