“…In this case the concentration of the metal in surface horizon was the effect not only of the geochemical background, but also of Hg characteristics, and anthropopression (Kabata-Pendias and Pendias 2001, Rodrigues et al 2006). The enrichment factor, calculated as a ratio of the Hg value in surface horizon and parent material (Ap/C), for the control was 1.79 and for the plot samples it ranged from 1.69-2.77.…”

The study was based on soil samples taken after the long-term fertilizer experiment where different doses of nitrogen and potassium were applied. The experiment was located at the Research Station of the UTP University of Science and Technology in Bydgoszcz (Poland). The long-term application of nitrogen and potassium fertilizers leads to changes in the concentration of mercury, soil acidification, reduction in total organic carbon, total nitrogen as well as affluence of available nutrients (P, K, Mg) and increased mobility of copper and zinc. The significant positive correlation between total mercury content in the soil and the content of N-NO 3 , Zn, N-NH 4 and the hydrolytic acidity value were stated.

Potentially toxic elements (PTEs) including nickel and chromium are often present in soils overlying basalt at concentrations above regulatory guidance values due to the presence of these elements in underlying geology. Oral bioaccessibility testing allows the risk posed by PTEs to human health to be assessed, however bioaccessibility is controlled by factors including mineralogy, particle size, solid phase speciation and encapsulation. X-ray diffraction (XRD) was used to characterise the mineralogy of 12 soil samples overlying Palaeogene basalt lavas in Northern Ireland and non specific sequential extraction coupled with chemometric analysis was used to determine the distribution of elements amongst soil components in 3 of these samples. The data obtained were related to total concentration and oral bioaccessible concentration to determine whether a relationship exists between the overall concentrations of PTEs, their bioaccessibility and the soils mineralogy and geochemistry.Gastric phase bioaccessible fraction (BAF%) ranged from 0.4% to 5.4% for chromium in soils overlying basalt and bioaccessible and total chromium concentrations are positively correlated. In contrast the range of gastric phase BAF for nickel was greater (1.4 to 43.8%), while no significant correlation was observed between bioaccessible and total nickel concentrations. However nickel BAF was inversely correlated with total concentration. Solid phase fractionation information showed that bioaccessible nickel was associated with calcium carbonate, aluminum oxide, iron oxide and clay related components, while bioaccessible chromium was associated with clay related components. This suggests that weathering significantly affects nickel bioaccessibility, but does not have the same effect on the bioaccessibility of chromium.

“…It has been found that many other factors, such as parent material (Rodrigues et al, 2006), organic matter (Lee et al, 1994), soil microbes (Barkay and Wagner-Dobler, 2005), played important roles in influencing the concentration and distribution of Hg in the soil. Clay minerals and oxides, particularly iron (Fe) and aluminium (hydr) oxides, controlled the transfer of Hg along soil profiles (Roulet et al, 1998).…”

a b s t r a c tMercury (Hg) in the agricultural ecosystem is a global concern because of its high potential toxicity. The objectives of this study were to determine the concentration and distribution of Hg in soils from three long-term experimental stations, i.e., Taoyuan (TY) and Qiyang (QY) in Hunan Province and Fengqiu (FQ) in Henan Province of China, and thus to assess the possible food and health risk of long-term applications of fertilizers. Soil samples at each site were collected from different fertilization plots and also from soil profiles with depths 0-100 cm. There were significant differences in soil Hg concentrations in 0-20 cm (A) or 20-40 cm (B) horizon among the three experimental stations. QY station showed significantly higher Hg concentrations than TY and FQ stations. However, there were no significant differences in soil Hg concentrations between A and B horizons at each station. It was concluded that the soil Hg concentrations at the three sites were mainly controlled by the parent materials. Moreover, chemical fertilizer, especially phosphorous fertilizers, could influence the soil Hg concentrations to some extent at the station with lower soil Hg concentrations, for example, at TY station. There were minimal amounts of Hg resulting from applications of the other chemical fertilizers and organic manure, and thus the fertilization had very low risk to the food security of the agro-ecosystems in the terms of Hg inputs and contamination.
