Ambient concentrations of PANs and other related air pollutants were monitored at an urban site in Beijing each August from 2006 to 2014. The NOx concentration decreased at a rate of 1.7 nL/(L/yr) (about 4%/yr), and the PAN concentration decreased at a rate of 0.03 nL/(L/yr) (about 3%/yr), while the O3 concentration increased at a rate of 1.5 nL/(L/yr) (about 4%/yr), indicating that the measures taken to cut NOx were effective for controlling PAN concentration. Beijing needs to strengthen the control of VOCs with reducing NOx emissions for reducing O3 concentration.

Key words: PAN, Beijing, regional photochemical pollution


2006—2014年夏季, 使用PANs在线监测仪对北京大气中PANs浓度进行监测, 期间NOx浓度以每年1.7 nL/L (约4%/a)的速率下降, PAN浓度以每年0.03 nL/L (约3%/a)的速率下降, O3浓度却以每年1.5 nL/L(约4%/a)的速率上升, 表明这些年采取的NOx治理措施对控制PAN浓度有效, 治理O3需要在控制NOx的同时加强对VOCs排放的控制。
