- •
Formation mechanism of a heavy haze-fog event that occurred in the YRD region of china was discussed.
- •
Nitrate exhibited the largest increase on the heavy haze-fog days.
- •
Increased biomass burning and atmospheric oxidizing capacity were the major reasons for the significant increase of OA.
- •
Short-distance transport, low wind speed and high RH were highly responsible for the formation of the pollution event.
