铝厂排放的废弃物和粉尘通常会造成土壤污染，并可能导致当地农作物中镉(Cd)的富集化。然而，铝厂污染土壤对蔬菜中Cd的富集规律及其健康风险尚不清楚。本研究在一个废弃的铝厂周围采集了12种蔬菜，共163个样品。结果表明，21%的叶菜类蔬菜Cd含量超过中国食品安全标准限值。从废弃铝厂四个方向不同距离采集的蔬菜中Cd含量差异不显著(p>；0.05)。结果表明，蔬菜中Cd的最高危害商数(HQ)和致癌风险分别位于距废弃铝厂1公里和7~10公里处。儿童和成人蔬菜中Cd的HQ值均在安全范围内，但儿童和成人蔬菜中Cd的CR值均高于美国环保局可接受的限值(10-6)，提示存在潜在的健康风险。由于儿童蔬菜摄入量较少，2-6岁儿童的健康风险高于7-17岁儿童和成人。不同蔬菜对Cd的摄取风险依次为菠菜、绿叶蔬菜、红叶蔬菜、卷心菜、萝卜茎类蔬菜、红薯叶、南瓜叶、豆类。
Wastes and dust discharged from aluminum factory generally result in soil contamination and may cause enrichment of Cadmium (Cd) in local crops. However, the pattern of Cd enrichment in the vegetables by contaminated soil of aluminum factory and their health risk are unclear. In this study, a total of 12 species of vegetables including 163 samples were collected around an abandoned aluminum factory. The results showed that 21% of the leafy vegetables with Cd exceeding Food Safety Standard Limit of China. The Cd in vegetables collected from different distances of four directions from the abandoned aluminum factory had no significant differences ( p >0.05). Our results indicate that the highest hazard quotient (HQ) and carcinogenic risk of Cd in vegetables are 1 km and 7-10 km away from abandoned aluminum factory respectively. The HQ values of Cd in vegetables for children and adults are within the safe range, however CR values of Cd in vegetables for both children and adults are higher than the acceptable limit of USEPA (10 -6 ), suggesting potential health risks. The health risks for children aged 2-6 years old are higher than aged 7-17 years old and adults due to the less amount of vegetable intake by children. The intake risks of Cd in different vegetables are spinach>green vegetables>red leafy vegetables>cabbage>radish leafy>stem vegetables>sweet potato leaves>pumpkin leaves>beans.
