摘要：

Changes of chemical forms of metallic zinc and zinc sulfide during the composting process of municipal solid waste in oxygen conditions have been determined. Speciation of zinc was carried out by means of sequential extraction. It has been found that contamination of the waste with Zn is dangerous to the environment because zinc accumulates in bioavailable forms - organically bound and carbonate. Zinc sulfide remains mainly in a less mobile sulfide form. The composting process increases the mobility of zinc insignificantly.
