Zhong Zhuang et al.

Summary: This study investigated the risk of cadmium accumulation in soil and wheat/maize systems in China. The results identified mining activities, sewage irrigation, industrial activities, and agricultural practices as critical factors contributing to cadmium accumulation. The study also developed cadmium enrichment models to predict cadmium levels in wheat and maize grains, providing valuable insights for risk assessments and predictions of cadmium accumulation.

Determination of Soil Cadmium Threshold for Potato

Wei Li et al.

Summary: In this study, pot experiments were conducted to investigate the characteristics of Cd transfer to potato tubers from two types of soil. The results showed that Log-normal and Burr III functions can be used to determine the sensitivity of different potato varieties to Cd and the soil Cd threshold. Furthermore, the Log-normal function can also be applied to fit the sensitivity distributions of different species for the development of appropriate soil Cd threshold values for conservation purposes.

A review of pristine and modified biochar immobilizing typical heavy metals in soil: Applications and challenges

Huabo Gong et al.

Summary: In recent years, the use of biochar for remediating heavy metal-contaminated soil has gained considerable global attention. This review summarizes the latest research on the immobilization of soil heavy metals using biochar in the past five years (until 2021). The methods, effects, and mechanisms of biochar and modified biochar in immobilizing typical heavy metals in soil are systematically presented. The reduction and precipitation of oxy-anionic heavy metals by biochar/modified biochar are the dominant mechanisms in reducing their toxicity. Pristine biochar can effectively immobilize cationic heavy metals. Commonly applied modification methods involve adding substances capable of precipitating heavy metals to the biochar. Additionally, the risks associated with biochar applications are assessed, such as leaching of certain heavy metals, biochar aging, and co-transportation of biochar nanoparticles with heavy metals. Future research should focus on the artificial/intelligent design of biochar for the remediation of multi-heavy metal-contaminated soil.

Prediction of Cadmium Transfer From Soil to Potato in Karst Soils, China

Ke Liu et al.

Summary: The study found that soil pH is a critical factor affecting the uptake of Cd by potatoes, and the Cd concentration in soil has a significant impact on the transfer of Cd. The prediction models showed that as the number of soil parameters increased, the predicted values gradually approached the measured values, and the probability distribution method was stricter in assessing Cd contamination of potatoes.

Response of Iron and Cadmium on Yield and Yield Components of Rice and Translocation in Grain: Health Risk Estimation

Abu Bakkar Siddique et al.

Summary: The study found that rice consumption is a major dietary source of cadmium which poses a potential threat to human health. Fe and Cd application can influence the yield and yield components of rice plants, as well as the dynamics of Cd in pore water and human health risks. Fe application was shown to reduce Cd levels and human health risks from rice consumption, especially in the Fe 2.0 treatment.

Co-pyrolysis of corn stover with industrial coal ash for in situ efficient remediation of heavy metals in multi-polluted soil

Yu Xia et al.

Summary: The immobilization efficiency of CA/BC for heavy metals was significantly enhanced due to increased pH value, surface functionality, and surface negative charge. The introduction of 5% CA/BC led to the highest reduction of leaching toxicity in polluted soils. The chemical speciation of Pb and Cd in soils changed remarkably, with bioavailable Pb and Cd mainly transformed into the most stable form of residual fraction.

Aging reduces the bioavailability of copper and cadmium in soil immobilized by biochars with various concentrations of endogenous metals

Hongbiao Cui et al.

Summary: The study found that dry-wet and freeze-thaw aging both affect the adsorption capacity of biochar for copper and cadmium, resulting in decreased bioavailability of Cu and increased bioavailability of Cd. Different biochars have different adsorption capacities, leading to varied effects on Cu and Cd. Careful assessment of biochar dosage and environmental risk is necessary before large-scale application.

Cadmium accumulation in wheat and maize grains from China: Interaction of soil properties, novel enrichment models and soil thresholds

Zhong Zhuang et al.

Summary: This study investigated the interactive effects of soil properties on the transfer of Cd from soil to grain, revealing that the interactive effects of soil properties play a more significant role in Cd accumulation in wheat grains than the soil Cd content. The results suggest that current Cd thresholds may not be entirely suitable for wheat and maize grains under different soil conditions, highlighting the importance of further research on the relationships between soil properties, soil Cd content, and grain Cd level.
