龙岩市PM10排放源污染元素富集因子分析

摘要

以福建省A层土壤元素背景值作为参考背景值，以Ti作为参考元素，应用富集因子分析方法对龙岩市内6种PM10主要排放源（道路尘、扬尘、钢铁厂尘、水泥厂尘、机动车尾气尘、燃煤尘）的污染元素进行了分析。分析结果表明，龙岩市各PM10排放源均存在着不同程度的污染元素富集污染现象，这些元素的富集污染程度易受人类活动的影响，并经过长时间的积累在城区内富集，使得城区内PM10的污染现象突出。研究结果为龙岩市大气环境治理提供了科学依据，有利于区域大气环境质量的改善。%The pollution elements of the six major emission sources in Longyan City have been analyzed by enrichment factor. These sources are road dust, fugitive dust, steel and iron plant dust, cement factory dust, vehicle exhaust dust and coal dust. The background value of the Strata A soil element in Fujian Province and Ti element are selected as reference during the analysis. It shows that the pollution elements in these emission sources are enriched to certain extent, and it is susceptible to the human activity. The accumulation of these pollution elements in a long duration makes PM10 a serious pollution in the urban center. The research provides a scientific basis for the air environment control and is helpful for improving the environmental air quality.
