Nitrogen Regulates the Distribution of Antibiotic Resistance Genes in the Soil–Vegetable System

Frontiers in Microbiology, 2022
The increasing antibiotic resistance genes (ARGs) in fertilizer-amended soils can potentially enter food chains through their transfer in a soil–vegetable system, thus, posing threats to human health.

Performance and mechanisms of greywater treatment in a bio-enhanced granular-activated carbon dynamic biofilm reactor

npj Clean Water, 2022
The potential of source-diverted graywater reuse mainly relies on the efficiency and cost of graywater treatment technology. Oxygen (O2) supply and utilization rate directly determine the energy consumption and pollutants removal rate in the biological ...

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Quantitative impact of manganese fertilizer across different growth stages on simultaneous reduction of soil arsenic and cadmium accumulation in rice grains

Ecotoxicology and Environmental Safety
Application of manganese (Mn) fertilizer is a promising strategy to reduce the accumulation of cadmium (Cd) and arsenic (As) in rice grains. However, the quantitative impact of Mn in co-contaminated soils on Cd and As accumulation at different growth ...
