| 摘 要： | 利用2016年夏季北仑区域的VOCs及臭氧在线监测结果,研究了北仑区域VOCs的浓度水平、组成及来源情况,同时还分析了区域的臭氧生成与VOCs之间的关系.结果表明:北仑的VOCs浓度整体水平与一些大城市相比较低,在VOCs组成中比例最高的为烷烃,臭氧生成潜势(OFP)贡献最高的为芳香烃;北仑的VOCs来源与北京和上海均有所不同,且北仑的机动车对VOCs的贡献特征值B/T为0.56,超过了临界值;北仑区域的臭氧生成主要是由本地的VOCs等的臭氧前驱体通过光化学反应生成.

| Abstract: | The concentration, composition, sources of VOCs and relationship between VOCs and ozone in ambient air of Beilun were analyzed by on-line monitoring method.The result showed that the concentration was lower than most cities in China.The greatest proportion in VOCs was alkane, and ozone formation potential calculation by VOCs showed that the aromatics make the greatest contribution.The sources of VOCs in Beilun were different from Beijing and Shanghai, and the B/T was 0.56, which was higher than the critical value of motor vehicle.The largest contribution of the ozone contribution was the local VOCs in Beilun area. |
