“…It shows that compared with ten years ago, the pollution of soil with Potentially toxic elements has an aggravating trend, especially as the content of Cd increases the most, followed by the increase of Cu, Pb, Ni, and As, and there is basically no change in Cr, Zn, and Hg. The survey found that agricultural activities, aquaculture, sewage irrigation, automobile exhaust emission, and traffic dust are the main factors [33,34]. The pollution of Cd mainly comes from the use of pesticides, fertilizers, and plastic films.…”

In order to understand the pollution status of potentially toxic elements (Hg, Cd, Cr, Ni, Pb, Zn, As, and Cu) in the surface farmland soil of black soil in Northeast China and its impact on human health, Hailun City, a representative area of black soil in Northeast China, was selected as the study area. The pollution degree, ecological risk, and health risk of soil and potentially toxic elements in this area were evaluated by the index of geoaccumulation method (Igeo), the potential ecological hazard index method (RI), and the health risk assessment model (HRA). The results showed that the average contents of eight potentially toxic elements in the soil in this area were higher than the soil background value in Hailun City, showing different degrees of accumulation. There are Cd and Hg pollution and ecological risks in the soil of Hailun City. Cd has slight, medium, strong, and extremely strong ecological risks, and the risk index ranges from 19.32 to 751.64; Hg takes second place. Children are more vulnerable to the health threat of potentially toxic elements, and oral intake is the main source of soil exposure risk. The potentially toxic elements As and Cr are more likely to cause human health risks.

“…TM adsorption by soil amendments occurs via physical adsorption, surface complexation, and ion exchange [ 106 ], which convert TMs to non-biousable forms [ 107 ]. The bioavailability of TMs in soil is the result of the interaction of organic matter, ions, redox conditions, and soil pH [ 108 ]. Soil pH exerts a great influence on TM content in rice; for example, the optimal pH for the adsorption of Ni (II) and Cu (II) is 6 and 5, respectively [ 109 ].…”

The threat of toxic metals to food security and human health has become a high-priority issue in recent decades. As the world’s main food crop source, the safe cultivation of rice has been the focus of much research, particularly the restoration of toxic metals in paddy fields. Therefore, in this paper, we focus on the effects of toxic metals on rice, as well as the removal or repair methods of toxic metals in paddy fields. We also provide a detailed discussion of the sources and monitoring methods of toxic metals pollution, the current toxic metal removal, and remediation methods in paddy fields. Finally, several important research issues related to toxic metals in paddy field systems are proposed for future work. The review has an important guiding role for the future of heavy metal remediation in paddy fields, safe production of rice, green ecological fish culture, and human food security and health.
