摘要
用化学质量平衡法对抚顺市望花、新华、东洲、站前、水库五个采样点的地面扬尘进行了污染物来源定量解析。计算结果表明 :对于望花、新华和站前三个监测点 ,土壤尘、建筑尘和燃煤飞灰的比例占据主要污染源的前三位。三个监测点土壤尘、建筑尘和燃煤飞灰所占比例的平均值分别为 :61.0 % ,17.7% ,15 .3 %。土壤尘、燃煤飞灰是东洲、水库点扬尘的主要来源。土壤尘、燃煤飞灰所占比例的平均值分别为 :5 4.5 % ,2 7.9%。所有扬尘样品中 ,冶金尘、汽车尾气均占较小比例 ,未发现燃油源的贡献。
Through the Chemical Method of chemical qualitative balance , the quantitative analysis of ground dust at the five monitoring spots located in the five areas of Wanghua, Xinhua, Dongzhou, Zhanqian and the Reservoir was carried out. The result showed that as far as the 3 spots are concerned in Wanghua, Xinhua and Zhanqian, dust from soil, from constructions and from burning coal (i.e. soot) rank the first 3 positions by proportion among the sources, which was 61.0%, 17.7% and 15.3% respectively. Yet at the spots in Dongzhou and in the Reservoir, the main sources of dust turned out to be the dust from soil and soot, which accounted for 54.4% and 27.9% separately. Among all the dust varieties monitored, proportions taken by metallurgical dust and by motor exhaust are comparatively small. No contribution by burning fuel was found.
