Cadmium

This study aimed to explore natural aging effect of distiller’s grain-derived biochar (DGB) at various amendment rates (2%, 4%, w/w) on wheat (Triticum aestivum L.) growth, development and Cd uptake in soil, and provide novel insights in effect mechanisms from views of soil Cd fractions and rhizospheric microbiota. Results showed that DGB amendment promoted wheat […]

This study investigated the effects of soil water content on Cd immobilization and uptake by leek with the combined application of biochar and organic fertilizer using mechanism experiment and pot experiment. Mechanism experiment was conducted with the three-layer mesh method, which can reveal the individual mechanisms and contributions of biochar and soil to Cd immobilization. […]

Abstract Cadmium (Cd) and lead (Pb) contaminated soils that are used for food production can lead to metal bioaccumulation in the food chain and eventually affect human health. In these agroecosystems, means by which Cd and Pb bioavailability can be reduced are desperately required, with biochar as a proxy for bioavailability reductions. Molecular Cd and […]
