摘要
目的:依武威市环保局2003年-2010年大气监测数据,对武威市空气质量进行评价。确定空气中的主要污染物,分析其对人群健康的影响,提出改善空气质量的建议和措施。方法用空气污染指数评价法,选用API指数划分武威市空气质量等级。结果评价结果显示武威市空气中的首要污染物为PM10,2003年空气质量为优良的天数占到全年的24.38%,之后逐年好转,到2010年全年空气质量均处于优良。结论近年来武威市空气质量逐渐好转,但危害人群健康的因素依然存在,因此需进一步加大环境综合治理,控制污染物排放,提高空气质量,保护人群健康。
According to the monitoring data of Wuwei Environmental Protection Agency from 2003 to 2010, an index system was established to evaluate the air quality status. The main factors influencing the population health were discussed. The air pollution index was used to evaluate the air quality status in Wuwei from 2003 to 2010. The number of days that air quality at the level of the I and Ⅱ grade accounted 24.38% for the weather in 2003. The trend analysis showed that the air quality status has been improved in recent years, but the pollutants affecting the population health still exists. Therefore, some proposals and measures were put forward to improve the local air quality level.
