Individual and Combined Effects of Nanoplastics and Cadmium on the Rhizosphere Bacterial Community of Hance.

Nanoplastics (NPs) and cadmium (Cd) coexist in soil, but the combined effects of NPs and Cd on the rhizosphere bacterial community remain unknown. In this study, high-throughput sequencing and PICRUSt2 functional analysis were employed to explore the individual and combined effects of polystyrene (PS) NPs (low concentration [N1, 100 mg·kg] and high concentration [N2, 1000 mg·kg]) and Cd (low concentration [C1, 0.6 mg·kg] and high concentration [C2, 4 mg·kg]) on the diversity, structural composition, and function of the rhizosphere bacterial community associated with Hance.

[Influencing Factors of Cadmium Content in Wheat Grain: A Meta-analysis and Decision Tree Analysis].

Rapid urbanization, industrialization, and agricultural intensification have resulted in serious soil problems, such as soil acidification and cadmium pollution, affecting food security and human health. Wheat is the second largest food crop in China and has a strong accumulation capacity for cadmium. Understanding the influencing factors of cadmium content in wheat grain is crucial to realize the safe production of wheat.
