Trends of PM.sub.2.5 concentrations in China: A long term approach
The fast economic growth of China along the last two decades has created a strong impact on the environment. The occurrence of heavy haze pollution days is the most visible effect. Although many researchers have studied such problem, a high number of spatio-temporal limitations in the recent studies were identified. From our best knowledge the long trends of PM.sub.2.5 concentrations were not fully investigated in China, in particular the year-to-year trends and the seasonal and daily cycles. Therefore, in this work the PM.sub.2.5 concentrations collected from automatic monitors from five urban sites located in megacities with different climatic zones in China were analysed: Beijing (40[degrees]N), Chengdu (31[degrees]N), Guangzhou (23[degrees]N), Shanghai (31[degrees]N) and Shenyang (43[degrees]N). For an inter-comparison a meta-analysis was carried out.
