摘要
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 n L/L(约4%/a)的速率下降,PAN浓度以每年0.03 n L/L(约3%/a)的速率下降,O3浓度却以每年1.5 n L/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。
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 03 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 reducing O3 concentration. control of VOCs with reducing NOx emissions for
