“…The coefficients of variation (CV) ranged from 0.09 to 0.35 indicating minor variability. The concentrations of Zn, Ni, and Cd were all slightly higher than those that have been previously reported in the other agricultural soils excluding Linfen (Liao et al 2007;Lu et al 2012;Liu et al 2015;Cao et al 2015), while Cu was lower than in the other agricultural soils (Table 2), indicating soil contamination of heavy metal as a result of excessive fertilization and pesticide application. The ordinary kriging interpolation method for heavy metal was used for the spatial distribution maps.…”

The values of magnetic susceptibility and Cu, Zn, Ni, Pb, Cr, Cd concentrations of 70 topsoil samples were analyzed and assessed for soil contamination in the Linfen basin of China. The contamination factor (CF) and pollution load index (PLI) were used to assess the degree of heavy metal pollution. All heavy metal concentrations in the soil were greater than the background values of Shanxi agricultural soils. PLI values ranged from 1.27 to 2.18 indicating significant soil contamination. Principal component analyses and correlation analyses were adopted for data treatment to identify heavy metal sources. Cu, Zn, Ni, and Pb were responsible for 31.2% of the total variance suggesting that these elements mainly originated from agrochemistry and atmospheric deposition. A positive correlation of magnetic susceptibility with Cu and PLI were observed in cultivated soils. This study shows that magnetic susceptibility measurements can be used as a technique in which different types of soil pollution can be distinguished and can also be used to rapidly monitor anomalies in areas that might require expensive and time consuming detailed chemical analyses.

“…Additionally impacts of cities along the Changjiang River have increasingly attracted people's attention (Zhu and Zang, 2001). Effects of industry and agriculture on heavy metal contamination are becoming more and more significant (Huang et al, 2007;Liao et al, 2007;Shao et al, 2008) so it is important and essential to monitor and identify the sources and prevent heavy metal contamination in the Changjiang River.…”

“…Meanwhile, the content of some nutrient elements like P, S, K, Ca, and Mg in the soil have been elevated due to excessive agricultural activities such as overfertilization. Soil pH also has decreased in the past decade, as has been reported by several recent studies [8,26]. The Se content and transfer in the soil-rice system in southern Jiangsu is unknown; the influencing factors and the key steps of Se transfer in the main production areas for food crops in China with elevated soil heavy metals and nutrient elements need to be studied.…”

“…Meanwhile, although Se is not an essential element for plants, low doses of Se are believed to be beneficial for plants and can be used to alleviate abiotic stresses such as cold, drought, high light, water, salinity, and heavy metals [5][6][7]. Like other microelements, selenium content in soils is influenced by parent materials and human activities, and the distribution character of Se contents in soil is heterogeneous [8]. In many regions of the world, soil Se concentration is low (<0.6 mg kg -1 ), especially in some parts of China [9].…”

Selenium deficiency in crops has become a subject of growing concern where soil Se concentration is low. The mechanisms of Se translocation in the soil-rice system is very complex and the influence of heavy metal elements and nutrient concentrations on Se translocation in the soil-rice system is unknown. Our study investigated concentrations of Se, heavy metals like Hg, Cd, and Pb, and nutrient elements like Ca, K, P, and S in soils and rice tissues (roots, stems, and grains) in different industrial regions in Jiangsu Province, China. The transfer of Se in the soil-rice system was calculated by transfer coefficients (TC Se ) in this study. The results showed that Se transfer from soil to roots and from stems to grain were key steps for controlled Se concentration in rice grains. The multiple linear regression analysis makes an implication that some elements influence the Se transfer significantly: soil K and Hg may suppress Se entering rice roots; B, Cu, and Mo in rice root may restrain Se transfer from root to stem; and S, Cr, P, and Mg in rice stem had negative effects on Se accumulation in rice grain. Therefore, reducing heavy metal pollution and managing fertilizer amounts may elevate Se concentration in rice grain, especially when Se concentration in soils is low.
