Efficiency evaluation for remediating paddy soil contaminated with cadmium and arsenic using water m

閱讀：2739 發(fā)布時(shí)間：2017-12-30

Paddy soils in many regions of China have been seriously polluted by multiple heavy metals or metalloids,such as arsenic (As), cadmium (Cd) and lead (Pb). In order to ensure the safety of food and take full

advantage of the limited farmland resources of China, exploring an effective technology to repair contaminated soils is urgent and necessary. In this study, three technologies were employed, including

variety screening, water management and foliage dressing, to assess their abilities to reduce the accumulation of Cd and As in the grains of different rice varieties, and meanwhile monitor the related yields.
