Open publisher page 1 citations

Abstract

During a composting of sewage sludge,we took several samples and analyzed them to reveal dynamics of the change of selected heavy metals including Zn,Cu,Pb,Cd,and Ni during the composting process.On the basis of related data obtained,we have discovered that the availability of the heavy metals was reducing steadily,but the total amounts of the heavy metals studied were kept at relatively constant.
