The response of mercury (Hg) transformation in soil to sulfur compounds and sulfur-rich biowaste application

Popis výsledku v původním jazyce

The mobility of mercury and its transformation as affected by different sulfur-rich amendments were investigated in a model laboratory incubation experiment. Two soils, Chernozem and Luvisol, differing in their physicochemical characteristics, were selected for the experiment. The soils were artificially contaminated with Hg by adding HgCl2 solution to a final concentration of 12 mg kg -1 of Hg in the soils. Subsequently, organic and inorganic amendments: (1) (NH4)(2)SO4, (2) L-cysteine, and (3) digestate, a biowaste from a biogas station, were applied and the soils were incubated for 21 days in the dark. Soil samples were collected after 1, 7, 14 and 21 days of incubation. At the individual sampling times 30 g of each soil was collected for determinations of pH, the mobile Hg pool, carbon derived from microbial biomass, and dehydrogenase activity.
