The uncertainty of methods for determining the heavy metal compounds, as well as problems in the comparison of the methods used, require further studies in this field. The aim of research is to study the fractional composition of Cu and Zn compounds in soil under model contamination conditions using different fractional methods. Chernozem Haplic was artificially contaminated with Cu and Zn acetates at rate of 300 mg kg ?1. Distribution of Cu forms in soil at the use of sequential fractionation by the Miller method...

The enterprises of the power industry worked by coal are one of the active sources of environmental pollution with heavy metals. The Novocherkassk State Power Station is the biggest power industry in the South of Russia. The atmospheric emissions contain heavy metals including Cu. Copper in soils exists in different chemical forms or types of binding. In environmental studies, the determination of these forms gives more information on trace metal mobility, as well as on their availability and toxicity, in comparis...
