英文摘要	We measured volatile organic compounds (VOCs) during the heating, non-heating, and sandstorm periods in the air of the Dushanzi district in NW China and investigated their concentrations, chemical reactivity, and sources. The observed concentrations of total VOCs (TVOCs) were 22.35 +/- 17.60, 33.20 +/- 34.15, and 17.05 +/- 13.61 ppbv in non-heating, heating, and sandstorm periods, respectively. C-2-C-5 alkanes, C-2-C-3 alkenes, benzene, and toluene were the most abundant species, contributing more than 60% of the TVOCs. Among these VOCs, alkenes such as propene had the highest chemical reactivity, accounting for more than 60% of total hydroxyl radical loss rate (L-OH) and ozone formation potential (OFP). Chemical reactivity was the highest in the heating period. The average reaction rate constant (K-OH-avg) and average maximum incremental reactivity coefficient (MIR-avg) of the total observed VOCs were (8.72 +/- 1.42) x 10(-12) cm(3)/mol.s and 2.42 +/- 0.16 mol/mol, respectively. The results of the source apportionment via the Positive Matrix Factorization (PMF) model showed that coal combustion (43.08%) and industrial processes (38.86%) were the major sources of VOCs in the air of the Dushanzi district. The contribution of coal combustion to VOCs was the highest in the heating period, while that of industrial solvents and oil volatilization was the lowest.
