食品中的镉和环境污染的影响植物性食品:在非污染环境中生长的植物性食品样品含镉很少超过0.2 mg/kg鲜重,镉在某些食品中的平均值也不超过0.1 mg/kg。某些根类作物如胡萝卜和防风,及某些叶类作物如莴苣和菠菜,比其它植物食品含镉多。相反,水果和果汁则含镉较低。生长在含镉高于1 mg/kg的土壤中的食品其含镉量明显高于植物食品中镉的正常浓度。例如:莴苣0.18 mg/kg(0.06)、菠菜0.63 mg/kg(0.08)、胡萝卜0.15 mg/kg(0.05)(括号内为正常镉
Impacts of Cadmium and Environmental Pollution in Foods Botanical Foods: Phyto-food samples grown in non-polluting environments rarely contain more than 0.2 mg / kg fresh weight of cadmium, and the average value of cadmium in some foods does not exceed 0.1 mg / kg. Some root crops such as carrots and windbreaks, as well as certain leaf crops such as lettuce and spinach, contain more cadmium than other plant foods. In contrast, fruits and juices contain lower levels of cadmium. Foods grown in soils containing more than 1 mg / kg of cadmium contained significantly more cadmium than normal concentrations of cadmium in plant foods. For example, lettuce 0.18 mg / kg (0.06), spinach 0.63 mg / kg (0.08) and carrot 0.15 mg / kg (0.05)
