分析了汽油和柴油发动机汽车排放的颗粒物中的PCDDs和PCDFs。汽油机汽车和柴油机汽车尾气颗粒物中PCDDs和PCDFs的同系物模式不同。还分析了连接到公路隧道的静电除尘器的悬浮颗粒物中的多氯二苯并对二恶英和多氯二苯并呋喃。汽油机和柴油机汽车悬浮颗粒物的同系物模式不同。汽油、柴油和悬浮颗粒物中的多氯二苯并对二恶英/多氯二苯并呋喃总浓度分别为0.21、0.87和26.0纳克/克。汽油、柴油和悬浮颗粒物中的I_TEQs水平分别为4.2、11和242 pg/g。
Vehicle exhaust particles from gasoline and diesel engine cars were analyzed for PCDDs and PCDFs. The congener patterns of PCDDs and PCDFs in exhaust particles were different between gasoline and diesel engine cars. Suspended particulate matter from electrostatic precipitator connected to a highway tunnel was also analyzed for PCDDs and PCDFs. The congener pattern of suspended particulate matter was different from both of gasoline and diesel engine cars. Total amounts of PCDDs/PCDFs sum concentrations in gasoline, diesel and suspended particulate matter were 0.21, 0.87 and 26.0 ng/g, respectively. The I_TEQs levels in gasoline, diesel and suspended particulate matter were 4.2, 11 and 242 pg/g, respectively.
