| 摘 要： | 为全面了解辽宁省大气可吸入颗粒物污染状况,2004年在省内选取了5个城市进行分季节采样,并对颗粒物中重金属元素含量和美国优先控制的16种多环芳烃(PAHs)进行了定量研究。结果表明,大气PM10和PM2.5中重金属元素和PAHs污染较重,且冬季高于其它季节,重金属元素和PAHs主要富集在PM2.5及以下细小颗粒物中。

| Abstract: | To comprehensively understand the pollution of absorbable particulate matter in Liaoning Province, we selected five cities in the province in 2004 to process seasonal sampling, and studied the content of heavy metal elements and 16 types PAHs in PM10 prioritized by USA. The result showed that concentration of heavy metal elements and PAHs in PM10 and PM2.5 is serious, which is higher in winter than in other seasons,and heavy metal dements and PAHs matter is mainly accumulated in PM2.5 and finer particulates. |
