| 摘 要： | 为了研究福州市主要菜地土壤和蔬菜的As含量及其健康风险,采集福州市郊区及周边县市菜地耕作层土壤样品98份、蔬菜样品111份,用氢化物发生原子荧光光谱法测定其砷含量。结果表明：福州市菜地土壤As含量范围为1.16~26.94 mg/kg,平均6.02 mg/kg,区域土壤As分布：马尾开发区〉连江县〉晋安区〉长乐市〉闽侯县;菜地蔬菜As含量范围为nd~0.0575 mg/kg,均值为0.0080 mg/kg,蔬菜砷对福州市部分人群存在一定的潜在健康风险;韭菜、豌豆苗、生姜和茼蒿吸收As的能力较强;紫菜薹、叶菾菜、菠菜、冬寒菜、大蒜、大白菜及大部分根茎类蔬菜、瓜果类蔬菜吸收As的能力较弱。

| Abstract: | In order to assess the risks to human health posed by elevated concentrations of As in soils and vegetables produced,98 soil samples and 111 vegetable samples were collected from plough layer of vegetable field on suburbs,cities and towns in Fuzhou.As concentration was measured using hydride generation atomic fluorescence spectroscopy（HG-AFS）.The results showed that：As concentrations in soils ranged from 1.16 to 26.94 mg/kg,with were ithmetic means of 6.02 mg/kg.The distribution showed that As contents of soils were different in different areas,with the order as Mawei Development Region,Lianjiang County,Jinan Region,Changle City and Minhou County.As concentrations in the edible plant portions ranged from less than the analytical detection limit to 0.0575 mg/kg fresh weight,with a mean of 0.0080 mg/kg fresh weight.Consuming vegetables with elevated As concentrations might pose a health risk to local residents.Chinese chives,garden pea seedlings,ginger and garland chrysanthemum had higher As bioconcentration factors,while purple cai-tai,leaf beet,spinach,Chinese mallow,garlic,Chinese cabbage,most of the rootstem vegetables and melon fruit vegetables had lower As bioconcentration factors. |
