常州市秋季大气PM2.5中多环芳烃污染水平及来源
Study on the Pollution Characteristics and Source Identification of PAHs on Ambient PM2.5 in Fall of Changzhou
【摘要】 为了研究常州市秋季大气PM2.5中多环芳烃的污染水平及其来源,在常州市布设了6个采样点,分别代表交通干道区、商业混合区、居民文教区、远郊区、工业区和对照点,于2013年10月进行大气PM2.5的采样,采用微波萃取-高效液相色谱法测定其中16种USEPA优控多环芳烃的浓度值,并分别通过比值法和因子分析法判断其主要来源。结果表明,常州市秋季大气PM2.5中多环芳烃的主要来源为煤燃烧和机动车排放。
【Abstract】 The ambient PM2. 5samples of 6 different functional areas( traffic area,commercial area,residential area,industrial area,suburb area and the control point) were collected in October 2013 of Changzhou. HPLC was used to determine 16 PAHs which EPA control preferentially with microwave assisted extraction. The characteristic ratios and factor analysis methods showed that coal combustion and vehicle emission were the major sources of PAHs on PM2. 5in fall of Changzhou.
