In fly ash–contaminated soils, metal buildup and translocation and their subsequent uptake in different parts of naturally growing plants were studied. The mean metal levels in soil and plants at uncontaminated site were significantly (p < 0.01) lower than the contaminated site. In polluted soils, metal enrichment factor (EF) was observed in order of Cd > Fe> Cr > Zn > Pb > Cu > Ni > Mn. The shoot enrichment factor (SEF) of Pithecellobium dulce (P. dulce) was Cd > Fe > Zn > Cr > Ni > Cu > Mn > Pb, whereas for Azadirachta indica (A. Indica) and Cassia fistula (C. fistula), the SEF was of the order Fe > Cd > Cr > Zn> Ni > Mn > Cu > Pb, respectively. Root enrichment factor (REF) for P. dulce was Cd > Fe > Zn > Ni > Cu > Cr = Mn > Pb, but in A. indica, the REF was Fe > Cd > Zn > Ni > Mn > Pb > Cu > Cr, and in C. fistula, this order was Fe > Cd > Zn > Ni > Cr > Cu > Mn > Pb. Metal mobilization ratio in plants at both sites were below 1, except Mn and Fe at contaminated site. Single and combined element pollution indexes (SEPI and CPI) and shoot contamination factor (SCF) at contaminated soil were higher than uncontaminated, but root contamination factor (RCF) between sites shows a variable response. From ANOVA results, metal concentration showed significant variation due to site, plants, location, and season interactions.

在被粉煤灰污染的土壤中，研究了自然生长植物不同部位的金属积累和转运以及它们随后的吸收。未受污染地点的土壤和植物中的平均金属水平显着低于受污染地点（p <0.01）。在污染土壤中，金属富集因子（EF）的顺序为Cd> Fe> Cr> Zn> Pb> Cu> Ni> Mn。拍摄富集因子的（SEF）金龟树（P。杜尔塞）为Cd>铁>锌> CR>镍>铜>锰>铅，而对于印楝（A.籼）和CASSI一个瘘（C.瘘），SEF的顺序分别为Fe> Cd> Cr> Zn> Ni> Mn> Cu> Pb。对于根富集因子（REF）P. dulce的为Cd>铁>锌>镍>铜> CR =锰>铅，但在印楝，在REF是铁>镉>锌>镍>锰>铅>铜> Cr，在瘘管中，该顺序为Fe> Cd> Zn> Ni> Cr> Cu> Mn> Pb。除受污染地点的锰和铁外，两个地点的植物中金属动员率均低于1。受污染土壤的单元素污染指数和综合元素污染指数（SEPI和CPI）和枝条污染因子（SCF）均高于未污染土壤，但站点之间的根部污染因子（RCF）显示出可变的响应。根据方差分析结果，
