Assessment of long-term particulate nitrate air pollution and its health risk in China.

ABSTRACT: Air pollution is a major environmental and public health challenge in China and the Chinese government has implemented a series of strict air quality policies. However, particulate nitrate (NO₃ ^-) concentration remains high or even increases at monitoring sites despite the total PM_2.5 concentration has decreased. Unfortunately, it has been difficult to estimate NO₃ ^- concentration across China due to the lack of a PM_2.5 speciation monitoring network. Here, we use a machine learning model incorporating ground measurements and satellite data to characterize the spatiotemporal patterns of NO₃ ^-, thereby understanding the disease burden associated with long-term NO₃ ^- exposure in China
