摘要
用撞击式分级采样器同步采集了北京市城乡结合部、郊区的2003年4个季节的不同粒径大气颗粒物样品,用气相色谱-质谱分析了其中的多环芳烃,并对两个地区大气颗粒物中的多环芳烃含量、分布及季节性变化特征进行了探讨。
The airborne panicle samples were collected onto the glass filter with a five-stage cascade impacter sampler. The samples were gathered from rural and urban area of Beijing in four seasons 2003 were analyzed. The aromatic fractions were analyzed by gas chromatography-mass spectrometry. The changes of the contents of priority PAHs of different seasons, different diameter of particles and different sites were discussed.
