摘要
利用在线单光子电离质谱仪(SPIMS),在2020年12月对珠三角地区某港口大气挥发性有机物 (VOCs)进行走航监测。该港口VOCs组分以烷烃(23.1%)和含氧含氮烃(19.0%)为主,其次是卤代烃(18.6%)和芳香烃(16.5%),特征污染物为丁烷/丙酮、二甲苯/乙苯、甲苯、戊烷/异戊烷、四氯乙烯和1,3-二氯丙烯。质谱走航监测方法不仅有利于快速了解港口的大气污染现状,还能为港口大气污染防治提供有效的技术支持和参考依据。
Abstract
Using online single photon ionization mass spectrometry (SPIMS), we monitored the volatile organic compounds (VOCs) in the atmosphere of a port in the Pearl River Delta region during December 2020. The VOCs in the port were mainly composed of alkanes (23.1%), and oxygenated and nitrogenous hydrocarbons (19.0%), followed by halogenated hydrocarbons (18.6%) and aromatic hydrocarbons (16.5%). The characteristic pollutants were butane/acetone, xylene/ethylbenzene, toluene, pentane/isopentane, tetrachloroethylene, and 1,3-dichloropropene. The mass spectrometric on-road monitoring method is not only beneficial for quickly understanding the current situation of air pollution in ports, but also provides effective technical support and reference basis for the prevention and control of air pollution in ports.
