“…Vertical distribution of Hg concentrations was consistent with the pattern in wastewater irrigation soils in Taiyuan, China (Zhang et al 2001) and the distribution of soils surrounding a chlor-alkali plant at Estarreja, Portugal (Inácio et al 1998). However, it differed from atmospheric source models, which showed the greatest Hg concentrations in a limited surface soil (Wang and Mou 1999;Tomiyasu et al 2003;Liu et al 2004;Feng et al 2006). Although there was a minor accumulation of T-Hg in surface soil profiles away from the outlet, the level was much lower than those near the outlet and the T-Hg concentrations below 40 cm of two profiles were similar (see Table 2).…”

“…Compared to the Hg accumulation in soils of mining areas (Tomiyasu et al 2003;Liu et al 2004;Fernández-Martínez et al 2005;Appleton et al 2006;Fernández-Martínez et al 2006;Feng et al 2006;Loredo et al 2006), the extent of Hg accumulation in soils of industrializing areas probably is not too much intense. However, heavy metal like Hg transfer from soil to crop or water depends not only on its accumulation but also on soil properties such as soil pH (Randall et al 2004;Jing et al 2007;Yang et al 2007), Eh (Chen 1996;Randall et al 2004), organic matter (OM) (Jing et al 2007;Yang et al 2007;Qian et al 2009), and residue time (Grimaldi et al 2008).…”

“…To some extent agricultural management practices could affect the characteristics of soil (Tomiyasu et al, 2003;Xiang et al, 2006;Manna et al, 2007). The results showed that human activities were influencing the soil Hg concentrations to the different extents.…”

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.
