“…Compared to the critical value of the CEQS (SEPAC 1995), no soil T-Hg concentrations in the Cambosols area exceeded the second most stringent critical value (500 μg kg −1 when pH>6.5). In comparison with total Hg concentrations in soils from other areas, the mean concentration in our study area was significant lower than the level reported for urban soil samples from Beijing, China (range 22-9, 400; median 260 μg kg −1 ) (Chen et al 2010), the agricultural soils near a petrochemical complex in Guangzhou, China (range 28-2, 400; mean 610 μg kg −1 ) (Li et al 2009), and the former industrialized urban areas of Beijing, China (range 220-76, 270; mean 4, 850 μg kg −1 ) (Luo et al 2009). In the acidic Anthrosols area, soil Hg at six sampling sites exceeded the critical value of the CEQS (300 μg kg −1 when pH<6.5).…”

“…The soil was amended with sulphur and planted for Hg stabilisation. According to Luo et al (2009) soil organic matter, nitrogen and sulphur contributed to Hg retention in soil, forming effective Hg soil mineral adsorbents, which was also observed by Barnett et al (1997). The increase of soil sulphide concentrations after granular sulphur addition, especially in planted variants showed plant rhizosphere participation in sulphide concentration.…”

Aims The paper presents results from plot experiments aimed at the development of an ecological strategy for soil contaminated with mercury. Meadow grass (Poa pratensis) was tested on mercury contaminated soil in a former chlor-alkali plant (CAP) in southern Poland for its phytoremediation potential. Methods The stabilisation potential of the plants was investigated on plots without additives and after the addition of granular sulphur. Biomass production, uptake and distribution of mercury by plants, as well as leachates and rhizosphere microorganisms were investigated, along with the growth and vitality of plants during one growing season. Results The analysed plants grew easily on mercury contaminated soil, accumulating lower amounts of mercury, especially in the roots, from soil with additive of granular sulphur (0.5 % w/w) and sustained a rich microbial population in the rhizosphere. After amendment application the reduction of Hg evaporation was observed.Conclusions The obtained results demonstrate the potential of using Poa pratensis and sulphur for remediation of mercury contaminated soil and reduction of the Hg evaporation from soil. In the presented study, methods of Hg reduction on Bhot spots^were proposed, with a special focus on environmental protection. This approach provides a simple remediation tool for large areas heavily contaminated with mercury.

“…In urban soil, Hg concentrations can be higher than the geochemical background values of soil in rural areas [15]. Elevated concentrations of a few to several mg of Hg per kg of soil have been recorded in various cities around the world [16][17][18], typically attributed to anthropogenic sources of enrichment [19,20]. There is a general paucity of information in terms of Hg concentrations in the urban soil environment.…”

Abstract:The present study documents the Hg content in 45 urban topsoil samples from the highly urbanized city of Athens, Greece. The Hg concentrations were quantified by applying aqua regia digestion on the <100 μm soil fraction followed by inductively coupled plasma-mass spectrometry (ICP-MS) with a detection limit of 5 μg·kg , which is the maximum concentration value expected to be present in normal uncontaminated soils. Results obtained by multivariate principal component and hierarchical cluster analysis incorporating a large suite of chemical elements were notably effective for elucidating the anthropogenic origin of Hg in the studied soil. The elevated concentrations are most likely related to site-specific point source contamination rather than to the widely documented influences from the vehicular traffic emissions in urban settings. Given the proximity of urban population to the contaminated urban soils, we suggest the implementation of different soil extraction tests with the aim to evaluate the fraction of soil Hg available for absorption by the human body.
