摘要
应用2005年丹东市大气总悬浮颗粒物(TSP)和可吸入颗粒物(PM10)监测数据,分析总结丹东市大气颗粒物的污染现状、时空分布规律。结果表明丹东市大气总悬浮颗粒物(TSP)达到国家二级标准。可吸入颗粒物(PM10)超过环境空气质量二级标准。PM10浓度季节变化特征为:春季和冬季污染较重,出现两个高峰;秋季次之,夏季污染最轻。
The contaminating condition and distribution of TSP in Dandong City are analyzed based on monitoring data of TSP and IP(PM_(10)) in 2005.The conclusion is drawn as follows: 1.the annual average concentration of TSP in Dandong City comes up to grade-two of the national standard;2.the annual average concentration of IP(PM_(10)) exceeds grade-two of the national standard,which is highest in the spring and winter and lowest in summer.3.Areas of Shiyan Primary School(traffic zone) and the old Financial College(residential zone) are polluted heavier,and areas of Watch Company(cleanliness zone) and the Industry Zone(industrial zone) are polluted lighter.
