| 摘 要： | 大气中的污染物对人体健康存在直接危害,对其分布特征和来源开展研究可为大气环境质量改善提供理论依据。本文通过对沈阳市1997~2006年间大气降尘布点监测数据进行分析,发现沈阳市降尘量总体呈现下降趋势,采暖期降尘量高于非采暖期;沈阳市各城区降尘量大小顺序为:于洪区>沈河区>和平区>大东区>铁西区>东陵区>皇姑区;对比同期环境质量公报与气象数据,燃煤和区域气象条件是影响沈阳市降尘的重要内在和外来因素。

| Abstract: | Air contaminants were hazard to human health,and for improving the air quality,the study of dustfall on distribution and source were carried out.The quantity of dustfall decreased and was higher in heating period than that in non-heating period,according to analyze the monitoring data in Shenyang from 1997-2006.The quantity of dustfall in different area of Shenyang was not equal,and the sequence was Yuhong district>Shenhe district>Heping district>Dadong district>Tiexi district>Dongling district>Huanggu dist... |
