性质:用以表示大气颗粒物中元素的富集程度,判断和评价颗粒物中元素的来源(自然来源和人为来源)的双重归一化数据处理的方法。选择某一元素作为参比元素(如Fe等),被测元素如为X,则可求出颗粒物中各被测元素对参比元素的比值,即相对浓度(X/Fe)颗粒物;同样可求得地壳中相应元素的比值(X/Fe)地壳。将此两比值相除,即得该被测元素的富集因子(EF),其表达式为:根据EF值可推断元素的主要来源。如EF>>1(取>10更为可靠),则此元素基本上来自人为活动。如EF≈1,则此元素主要来源于地壳、土壤。由此可半定量地估算某种污染源(如风砂土壤的贡献率,也可获得某地区或污染源颗粒物中元素的富集程度,评价其污染状况。
