| 摘 要： | 锑(Sb)是一种有毒致癌元素, 一些自然和人为因素已造成我国部分地区土壤、水体及农产品受到严重的锑污染。环境中高含量的锑不仅影响农作物生长、降低其产量, 如果通过食物链被人体大量吸收, 还会引起严重的健康问题。研究锑在植物体内的富集特征, 对于保护环境与人体健康具有重要的现实意义。该文对当前锑在环境中的含量、污染状况、植物对锑的吸收、代谢以及锑对植物的毒害作用等方面的研究现状进行了综述。同时建议今后应加强以下3方面的研究: (1) 锑在生物圈迁移与转化特征; (2) 植物对锑的吸收、转运和代谢机制及锑的毒害作用机理; (3) 锑污染土壤及水体的植物修复技术。 |

| Abstract: | Antimony (Sb) is a toxic carcinogenic element. In some areas of China, soil, water, and agricultural products have been severely polluted by Sb because of particular natural and artificial factors. High levels of Sb in the environment can threaten the health of humans via the food chain. To protect the environment and human health, we must investigate the behavioural characteristics of Sb in plants and the biosphere. Here, we summarize recent progress in research on the mechanisms of absorption, metabolism and toxicity of Sb in plants. Attention must be paid to (1) migration and transformation behaviours in the biosphere; (2) mechanisms of uptake, transport, metabolism and toxicity in plants, especially in crops; and (3) technologies for phytoremediation of contaminated soil and water. |
