《Potential factors and mechanism of particulate matters explosive increase induced by free radicals oxidation》
The air quality index（AQI）of Lanzhou in December 2017ranked 71 among the 74 major monitored Chinese cities，reaching up to 481 because of the dusty weather.These concentrations typically record periodic“clean–polluted–clean”cycles for a few days.However，due to the unique climatic factors and geographical conditions，the PNC remains higher even in the normal weather；occasionally，the PNC sharply increases in a short time period.This phenomenon is termed“particulate matter explosive increase”and the cause of it deserves more studies in future.As shown in Table 1，the PNC（0.2μm
