lignin, clay minerals, fly ash, blast furnace sludge, red mud, zeolites, biomass and bagasse fly ash) for the removal of heavy metals from wastewater [6,7,11,13]. Coal fly ash is a mineral waste from coal-burning power plants. In 2008 in Romania, coal provided 42.5% of the total supply of elec-tric power to generate electricity.
Of the elements studied, 10 to 60% of the As, Br, Cr, Sb, Se, Ni, Pb, and Sr dissolved within a 24-hour period. Elements which were less than 10% soluble in 24-hours included Cu, Zn, Na, La, Sc, Fe, Co and Eu. Littleneck clams (Protothaca staminea) were exposed to coal fly ash in flowing seawater for a 25-day period.
