“…The effect of high contents of metals: Pb, Cd, Zn and Cu in soil on soil pH decrease was demonstrated by Friedlova (2010). Soil pH decrease may affect increased uptake of heavy metals from soil by plants (Fitamo et al 2011, Chibuike and Obiora 2014). In all experimental pots, we observed an increase in the electrical conductivity of soil along with its increasing contamination with heavy metals.…”

“…The addition of manure into the soil will increase the CEC so that it can increase the absorption of heavy metals in the soil. Based the result of Fitamo et al of the same soils revealed that considerable proportions of the total levels of heavy metals were extracted from the non-residual fractions, and CEC and pH were key factors in the distribution of heavy metals among these fractions [17]. The increase of CEC will increase the exchangeable metal.…”

Industrial waste containing heavy metals used for wetland irrigation will affect the heavy metals content in the soil. The accumulation of heavy metals in the soil may result in reducing microbial activity, soil fertility, soil quality, and heavy metals compounds in agricultural products. Agricultural products contaminated by heavy metals can influence human health. The purpose of this study was to reduce the Pb content in Pb contaminated paddy fields. This research was conducted in a contaminated paddy field using factorial research and a Completely Randomized Block Design consisting of 3 factors : P (Inorganic fertilizer), B (Bioremediation agents), T (Ramie). Every treatment combination was repeated 3 times. This study used a combination of Ramie with Rhizobium sp. I3 or manure as bioremediation agents to improve Pb uptake by plants so could decrease soil Pb. The results showed that the bioremediation agents were able to increase Pb uptake by Ramie. Rhizobium sp. I3 gave the highest Pb uptake of 103.77 mg.kg-1 or 2 more times than control. The best treatment in decreasing Pb is with inorganic fertilizer, Rhizobium sp. I3 and Ramie (P1B1T1) with Pb soil 8.57 mg.kg-1 or 8.4 % than control and with inorganic fertilizer..

“…This may lead to lower Cd concentrations in potato soils than those in oats soils. Previous studies observed that roots of oats had the potential to absorb Hg from soils [73]. Xie et al [44] found that oats were easier to concentrate Hg, followed by Cd and Cr.…”

The distribution of heavy metals in the agricultural areas from a cattle-producing area near the Zhangbei Dam grassland, Hebei province, China, was investigated for providing the basis for the control of pollution in a rural farmland. Fifty-three surface soil samples including 28 soils of potato and 25 soils of oats were collected and analyzed for the distribution of Cd, Cu, Pb, Zn, Cr, As, Hg, and Ni. Furthermore, the ecological risk of soils contaminated with heavy metals was evaluated by employing the single factor index, the Nemerow comprehensive pollution index and geo-accumulation index, and potential ecological hazard index. The results showed that the contents of the eight heavy metals in soil planted with potato were below the risk screening values. The single factor index in soils planted with hulless oats showed that the concentrations of Cd, Hg, and Ni surpassed the Chinese screening limits by 8%, 4%, and 8%, respectively. According to the geo-accumulation index, 4% of samples reached the level of medium ecological risk for Cd. According to the results of ecological risk assessment, the studied soils generally showed a mild pollution degree. According to the health risks assessment results, the carcinogenic risks should be considered non-negligible. Arsenic is the dominant carcinogenic pollutant for human beings in the county. The main sources of pollution are mining and application of fertilizers.
