Abstract

This project comprised laboratory and large scale lysimeter studies of the leaching properties of coal fly ashes and flue gas desulphurisation (FGD) products from the spray dryer absorption (SDA) process, laboratory and lysimeter investigations of the mobility of two key components, Cr(VI) and Mo(VI), of coal combustion residue leachates in soils, simulation of the migration of Cr(VI) and Mo(VI) in soil using numerical modelling of laboratory results, field investigations at an old coal fly ash disposal site, and theoretical calculations of ageing processes of coal fly ash. The overall purpose was to improve the tools available for reliable assessment of the environmental impact of disposal of coal combustion residues.
