摘要

本研究比较了越南杜延海热电厂煤及其燃烧副产物飞灰的元素组成。粉煤灰中主要元素（Si、Al、K）和微量元素（Sn、Mn、Sr）的含量显著高于粉煤灰。粉煤灰中的有害金属含量达到了越南和粮农组织的土壤限制，但超过了世卫组织的标准，比煤的浓度高1.4-5.6倍。Cr、Mn、Ni、Cu、Zn富集因子增大，As富集因子减小。危害指数（HI）低于1，表明非致癌风险可以忽略不计。然而，镍和铬的致癌风险（CR）超过了安全阈值，这突出了监测化学形式和元素相关性对处置场所工人安全的必要性。

Elemental composition of fly ash in thermal power plants and estimation of health hazard

This study compared the elemental composition of coal and its combustion byproduct, fly ash, from the Duyen Hai thermal power plant, Vietnam. Fly ash exhibited significantly higher concentrations of major (Si, Al, K) and trace (Sn, Mn, Sr) elements. Hazardous metal levels in fly ash met Vietnam and FAO soil limits but exceeded WHO standards, showing 1.4–5.6 times higher concentrations than in coal. Enrichment factors for Cr, Mn, Ni, Cu, and Zn increased, while that of As decreased. The hazard index (HI) was below 1, indicating negligible non-carcinogenic risks. However, carcinogenic risks (CR) from Ni and Cr surpassed safe thresholds, highlighting the necessity of monitoring chemical forms and elemental correlations for worker safety at disposal sites.
