What is Net effect of air pollution controls on health risk in the Beijing–Tianjin–Hebei region during the 2022 winter Olympics and Paralympics about?
Due to the non-linearity in ozone (O 3 ) formation, reducing the emission of nitrogen oxides (NO x ) may increase O 3 concentration. Given the counteractive O 3 response to NO x reduction, overall impact of air pollution controls can be ambiguous when the assessments focus on the changes in pollutant concentrations. In this study, a risk-based method was used to gauge the net effect of air pollution controls on mortality risk in the Beijing-Tianjin-Hebei (BTH) region during the 2022 Winter Olympics and Paralympics (WOP). This mega-event presents a unique opportunity to investigate the efficacy of deep cuts in pollutant emissions. Results show that O 3 concentrations greatly increased as nitrogen dioxide (NO 2 ) concentrations decreased in the BTH. Due to the active photochemical formations, O 3 became the dominant pollutant that affected human health during the WOP. Despite the substantial O 3 increases, the health benefits of NO 2 reductions overwhelmed the adverse health effects of O 3 increases in most regions of the BTH (at 81 out of 112 stations). After considering the impacts of particulate matter, the integrated health risk of air pollution mixtures declined
