J. Ciba et al., CHANGES OF CHEMICAL FORMS OF ZINC AND ZINC-SULFIDE DURING THE COMPOSTING PROCESS OF MUNICIPAL SOLID-WASTE, Water, air and soil pollution, 93(1-4), 1997, pp. 167-173
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 seque
ntial extraction. It has been found that contamination of the waste wi
th Zn is dangerous to the environment because zinc accumulates in bioa
vailable forms - organically bound and carbonate. Zinc sulfide remains
mainly in a less mobile sulfide form. The composting process increase
s the mobility of zinc insignificantly.
