Heavy metals in a municipal solid wast deposition cell
The physical and chemical changes of a waste mixture consist ing of mumcipal solid waste (MSW) and sewage sludge were investigated during the anaerobic waste stablilization phases of the mixture. The emphasis of this study was the behavior of heavy metals. The waste was deposited in a test cell in 1973. It was found that the waste mass decreased by about 30% (wt) during the years 1973 to 1993 and
