Abstract

The sequential extraction procedure was proposed and used to study of mercury speciation in real samples of soil. Samples of soil profiles together with bedrock and coal were taken from sampling spots in the vicinity of surficial coal beds in an area with natural coal outcrops. The proposed sequential extraction procedure involves the following fractionation: organic mercury compounds, extractable mercury in an acidic medium, mercury bound to humic substances, elemental Hg and mercury bound to complexes, HgS and residual mercury. The significant distribution of mercury between the two portions-mercury bound to humic substance and HgS was determined in the majority of samples. The mercury bound to humic substances created a significant contribution, especially to the top layer of soil. On the other hand, HgS was the dominant form in the samples from lower layers of the soil profile. The mercury content in the samples did not show a distinct mobility. The influence of soil parameters on the mercury distribution in the studied samples was investigated and discussed.
