Background and aims Efficient accumulation of arsenic (As) in rice (Oryza sativa L.) poses a potential health risk to rice consumers. The aim of this study was to investigate the mechanisms of uptake, transport and distribution of inorganic arsenic (Asi) and dimethylarsinic acid (DMA) in rice plants. Methods Rice was exposed to Asi (As(V)) and DMA in hydroponics. High-performance liquid chromatography...
Background Rice can accumulate arsenic (As) to relatively high concentrations due to the general flooding practices in rice cultivation, and organic matter in the soil strongly affected As bioavailability to rice plants. The influence of organic matter input on the As transformation in paddy soil and As uptake into rice plants is an area that is rarely investigated. Methods Biogas slurry (BGS),...
