Urban air particulate pollution is a known cause for adverse human health effects worldwide. China has encountered air quality problems in recent years due to rapid industrialization. Toxicological effects induced by particulate air pollution vary with particle sizes and season. However, it is not known how distinctively different photochemical activity and different emission sources during the day...
Data on aerosol particle size distributions between 0.01 and 10 μm were combined with 222 Rn and 210 Pb particle activities to analyze black carbon characteristics. The activity ratio 210 Pb/ 222 Rn was applied to estimate the aerosol and black carbon age. Aerosol with high concentration in the size range of 0.100-0.320 μm was...
