Mitigation of severe urban haze pollution by a precision air pollution control approach.

ABSTRACT: Severe and persistent haze pollution involving fine particulate matter (PM_2.5) concentrations reaching unprecedentedly high levels across many cities in China poses a serious threat to human health. Although mandatory temporary cessation of most urban and surrounding emission sources is an effective, but costly, short-term measure to abate air pollution, development of long-term crisis response measures remains a challenge, especially for curbing severe urban haze events on a regular basis. Here we introduce and evaluate a novel precision air pollution control approach (PAPCA) to mitigate severe urban haze events. The approach involves combining predictions of high PM_2.5 concentrations, with a hybrid trajectory-receptor model and a comprehensive 3-D atmospheric model,
