[Distribution and characters of heavy metals from municipal solid waste incinerator fly ash].
The distribution and characters of heavy metals from municipal solid waste incinerator fly ash was studied in East China. The result indicate that heavy metals in fly ash were mainly distributed in fine particles. The heavy metals including Cd, Pb, Mg, and Cu could migrate easily from fly ash while Ag and Sn would be more stable. The metal mobility changed with the pH level. For environmentally important metals such as Cd, Co, Cu, Mn, Ni, Pb, and Zn, the increase in mobility due to the decrease in pH was more pronounced and significant than for other elements, while Cr and As with the opposite condition.
