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).
