| 摘 要： | 为了降低Cd、Pb污染菜地的食物链风险,在Cd、Pb全量及田间管理等不一致的广州市城郊菜地,进行了2个大田小区试验来研究29种常见叶菜的Cd、Pb吸收特征,并通过信息叠加法来筛选Cd、Pb低富集叶菜。结果表明,供试叶菜地上部Cd、Pb含量都没有超过我国食品中污染物限量标准,Cd在叶菜中的迁移能力较Pb强;叶菜Cd含量呈现科属亲缘特征,莴苣属和番薯属叶菜地上部Cd含量显著高于芸苔属(p<0.05)。同时筛选到3种低Cd叶菜和6种低Pb叶菜,在广州近郊菜地种植,其可食部分Cd、Pb较低。

| Abstract: | To reduce the food chain risk for vegetable soils contaminated Cd,and/or Pb,two field trials were conducted to investigate Cd or Pb uptake by 29 varieties of familiar leaf vegetables and to screen leaf vegetables with lower Cd or Pb content by using the informational superposition method under the condition of suburb vegetable soils in Guangzhou City.The results showed that the shoot Cd or Pb content of tested vegetables was lower than the national maximum levels of contaminants in foods.Cd in the tissues o... |
