为保证水稻籽粒中镉含量符合食品安全标准，有必要确定适宜的水稻土镉健康风险毒性阈值。本研究以我国水稻主产区的20个水稻品种为试材，采用盆栽试验，研究了0（CK）、0.3 mg kg（-1）（T1）和0.6 mg kg（-1）（T2）Cd处理下水稻土-水稻系统中Cd的转化规律。结果表明，水稻籽粒中Cd含量存在显著差异（P
It is imperative to derive an appropriate cadmium (Cd) health risk toxicity threshold for paddy soils to ensure the Cd concentration of rice grains meet the food safety standard. In this study, 20 rice cultivars from the main rice producing areas in China were selected, and a pot-experiment was conducted to investigate transformation of Cd in paddy soil-rice system with 0 (CK), 0.3 mg kg(-1) (T1) and 0.6 mg kg(-1) (T2) Cd treatments in greenhouse. The results showed that Cd concentrations of rice grains existed significant difference (P
