A total of 18 elements viz. Si, Al, Fe, Ca, Mg, K, Na, Sr, V, Zn, Mn, Cr, Cu, Pb, Ni, Co, As and Cd were analyzed in coal, fly ash and bottom ash samples collected across India using an EDXRF technique. Various indices such as element enrichment ratio, enrichment factor (with respect to crustal average) and mineral composition were calculated. Around 95% of mass was reconstructed using the concentration of elements in this study for fly and bottom ash.
使用能量色散X射线荧光光谱（EDXRF）技术，对在印度各地采集的煤、粉煤灰和底灰样本中的总共18种元素，即硅（Si）、铝（Al）、铁（Fe）、钙（Ca）、镁（Mg）、钾（K）、钠（Na）、锶（Sr）、钒（V）、锌（Zn）、锰（Mn）、铬（Cr）、铜（Cu）、铅（Pb）、镍（Ni）、钴（Co）、砷（As）和镉（Cd）进行了分析。计算了各种指标，如元素富集比、（相对于地壳平均值的）富集因子和矿物成分。在本研究中，利用粉煤灰和底灰中元素的浓度重建了约95%的质量。
