This study investigated the influence of sea–land breezes on nocturnal spatial and temporal distribution ozone (O3) its potential effects particulate nitrate formation in Qingdao, a coastal city northern China.

Notably, time lag peak concentration observed southern areas peaking before rural During this period, combined pollution PM2.5 also observed. These findings indicated nighttime concentrations, coupled atmospheric oxidation, would likely promote secondary gaseous precursors PM2.5.

Abstract Particulate matter (PM) emission from coal mining activities is inevitable and a significant concern worldwide. American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) one of the most widely used dispersion models for predicting air PM in mines. However, validation AERMOD-predicted concentration large mine complex has not been reported. So, this study, AERMOD predicted was validated against concentrations measured by nine continuous ambient quality monitoring stations (CAAQMS) stationed Singrauli complex. The contains mines across 438 square kilometers, with around 129 pollution sources chiefly area, pit, line categories. PM10 PM2.5 peak during summer (204.58 µg/m3) winter (67.67 µg/m3), respectively. model predicts (500–1200 (100–800 season. reveals that region's wind movement caused land lake breezes predominant driver surface dispersion. In season, atmospheric inversion increases ground-level region. cannot represent vertical PMs summer, resulting an underestimation concentration. statistical shows underestimates all seasons years. model's prediction accuracy (R2 = 0.38) 0.56) also low. Finally, it can be concluded are accurate complexes but more suitable individual
