| Description |
Meeting the ever-growing demand of global energy in an eco-friendly manner necessitates the evaluation
of coal and its combustion residues. For management of coal combustion and its residues on sustainable
basis, characterization of trace elements and polycyclic aromatic hydrocarbons (PAHs) is imperative. The
feed coal, fly ash, and bottom ash from a power plant (Unchahar, India) were evaluated. Feed coal is low
grade high volatile sub-bituminous. Quartz and kaolinite are the predominant minerals in the coal,
whereas quartz, mullite, and anhydrite in the ashes. Si > Al > Fe > Ca are the major elements in coal
and it ashes. As compared to coal, most of the elements are enriched in the ashes; especially As, Cu,
Ni, Pb, and Zn are highly enriched (enrichment factor > 5.0) in fly ash. Cluster analysis showed that As,
Co, and Cd are associated with the ash forming elements like P–Mg–Ca–S; Ni, V, Cu, Pb, Zn, and Cr with
Al-silicate minerals. Leaching study revealed that the trace elements are within the permissible limits for
industrial effluents. The total PAHs content was much higher in coal (4542 lg kg�1) than fly ash
(32.4 lg kg�1) and bottom ash (10.1 lg kg�1). High molecular weight PAHs were predominant in coal
and fly ash, low molecular weight PAHs in bottom ash.
