摘要
采用手工监测(重量法),对宁夏石嘴山市大武口区城区灰霾天气下两个主要空气污染源:崇岗工业园区和某火电厂周边大气中颗粒物PM10进行监测,监测结果显示:在灰霾状况下,石嘴山市区颗粒物粒径主要分布在0级(9.0-10.0μm)和1级(5.8-9.0μm),所含质量分别占总采样量的54%和25.7%.除去自然因素外,崇岗工业园区大气颗粒物(粒径小于等于10μm)(PM10)对大武口市区PM10贡献率为50%-60%,大武口电厂对大武口市区PM10的贡献率均为40%-50%左右.同时,大武口城区PM10中阴阳离子含量表明,城市汽车尾气也是造成大武口市区PM10浓度升高的原因。
Monitored particles the PM10 of the atmosphere in chung post industrial park and a coal- fired power plant by using the weight method. Monitoring results show that: in the ash haze conditions, the urban particle size are mainly distributed in a level 0 (9.0 - 10.0 microns) and 1 (5.8 - 9.0 microns)in shi zui shan,and the quality of accounting for54% and 25.7% of the total amount of sampling. Remove the natural factors, atmospheric particulates (PM10) ( particle size less than or equal to 10 microns) of chung post industrial park accounted for 50% - 60% in da wu kou , and the contribution rate of PM10 were 40% -40% to the coal - fired power plant. At the same time the automobile exhaust is the cause of its mouth urban elevated PM10 concentration.
