摘要
测定了长沙市区火车站附近2012年11月至2013年4月连续六个月PM2.5和PM10,用超声波法提取和液相色谱测定了相应颗粒物中的苯并(α)芘的含量。分析了颗粒物与苯并(α)芘相互之间关系。结果表明,采样点位在采样期间的PM2.5和PM10以及其所含苯并(α)芘的含量均有超过环境质量标准二级浓度限值的时段,长沙市环境空气中存在苯并(α)芘污染,它的含量与其结合的颗粒物质量浓度存在相关性。
PM10 and PM2.5 of Changsha city near the train station was determined continuously from November 2012 to April 2013 for six months. Benzo（α）pyrene in PM10 and PM2.5 was extracted by ultrasonic instruments and determined by liquid chromatography. The relationship was analyzed between particulate matters and benzo（α）pyrene. The rusults showed that PM10, PM2.5 and benzo（α）pyrene in particulate matter exceeded second standard of the air quality standards during the sampling. Benzo（α）pyrene pollution existed in environmental air of Changsha. It was found that the concentration of benzo（α）pyrene was correlation with the concentration of combinted particulate matters.
