1.
Validation of methodology for determination of the mercury methylation potential in sediments using radiotracers

A method using radiotracer 197-Hg of high specific activity was developed and validated. The method allows to study mercury oxidations and reduction in aqueous media, as well as partitioning of Hg (II) between aqueous and solid particles. This is very useful toll to study mercury behaviour in wet FGD in laboratory scale experiments.

2.
The role of flue gas desulphurisation in mercury speciation and distribution in a lignite burning power plant.

The present study was conducted on a lignite burning thermal power plant which combines five power units totalling of 775 MW with a yearly consumption of about 4 million tons of lignite. All units are currently connected to two wet limestone FGD plants. A mass balance for mercury and 39 trace and major elements was estimated in two units under different operational conditions. Among other trace elements the distribution of volatile As, Br, and Se were also followed, showing that Se and Br are enriched along with Hg in the FGD products.
