“…Content of As, Cr and Zn in the soil samples was comparable with arable and residual topsoils in Northern Estonia (Table 7), but average concentration of Pb was higher. Nevertheless, investigated soils contained less Pb than soils in the Tallinn region (Table 7) as well as soils from urban parks (66.2 mg/kg) in Beijing [53] or polluted soils (50.9 mg/kg) in Poland [54].…”

“…Similarly, the contents of Cd and Pb in a mining area of Shanxi in China and in Slovakia were higher in the surface soil (Li et al 2015b;Musilova et al 2017). This occurred because mining areas contain a great deal of heavy metal-polluted dust, which will float down to the surrounding environment (Galiulin et al 2002) and cause heavy metal pollution in the surface soil though wind and transport. For the soil aggregates, both the total and effective Cd and Pb gather mainly in the macro-aggregates and colloid.…”

Background: Cd and Pb were the main pollution elements in Pb-Zn mining areas. Several studies have focused on heavy metal pollution and risk assessment in the Huize Pb-Zn mining area. In the present study, the soil aggregate composition, chemical properties, contents and chemical fractions of Cd and Pb were analysed in soils at depths of 0-60 cm in the Huize Pb-Zn mining area. Agricultural soils were sampled at depths of 0-20, 20-40 and 40-60 cm surrounding the Pb-Zn mine. The particle size fractions were determined by the aggregate composition of macroaggregates (0.25-2 mm), micro-aggregates (0.053-0.25 mm), silt (0.002-0.053 mm) and colloid (< 0.002 mm).Results: There was a large proportion of the macro-aggregate (52.4%) and less of the colloid (1.8%). With a decrease in particle size, the pH, organic matter contents, cation exchange capacity, and free iron oxide increased in the soil aggregates. Although the total and available Cd and Pb contents were highest in the colloid, the macro-aggregate maximally contributed to the total Cd (48.18%), total Pb (53.48%) and available Pb (47.42%) content, and the colloid maximally contributed to the available Cd (47.21%) in soils. The Cd and Pb existed primarily as residual fractions, followed by Fe-Mn oxide fraction and the exchangeable fraction in soil aggregates. There were higher distribution factors for the residual and exchangeable fractions of both Cd and Pb in the colloid (DF > 33). Furthermore, there were close correlations between the Cd and Pb fractions and the pH and the phosphorus content and between the exchangeable Pb content and the content of organic matter, cation exchange capacity, and free iron oxide in soil aggregates. Conclusion:Cd and Pb existed mainly in the micro-aggregate and colloid and that their chemical fractions were closely related to the chemical properties in soil aggregates of the polluted farmland.

“…A proportion of heavy metals is taken up by plants and leached by surface and subterranean runoff. The need to control atmospheric contamination of soils by heavy metals and take preventive and remediation measures is dictated by the serious ecological consequences of this contamination, as observed in different regions of the world (Galiulin et al, 2002).…”
