间四联苯的环境新意义

The New Environmental Significance Of 5′-Phenyl-1、1′:3′、1″-Terphenyl

在以往报道中,间四联苯主要来自于聚苯乙烯等聚合物的焚烧.而在汽车尾气、民用炉灶、香烟烟雾等其他污染源中均未检测出.北京市春季主要污染源为汽车尾气、煤等其他植物的燃烧,并不存在垃圾焚烧炉.而在北京市不同功能区春季大气中普遍检出间四联苯,因此我们认为间四联苯并不一定只来源于垃圾焚烧,预示着在一些化石燃料或植物的燃烧产物中也可能存在间四联苯,间四联苯具有新的环境意义.

mTBP was detected in the aerosol samples of different function areas in Beijing at first. The content of the mTBP was slight higher in the different function areas. We think that the mTBP is not only related to rubbish incineration, but is also probably related to fossil fuel and plant incineration.
