蚌埠市蔬菜重金属含量及食用安全性评价

Heavy metal content and edible safety evaluation of vegetables in Bengbu

  • 摘要: 测定了蚌埠市蔬菜中重金属质量比,采用单因子污染指数法、综合污染指数法和目标危害系数法对其污染程度及食用安全性进行评价。结果表明,蚌埠市蔬菜中Pb、Cd、Cr、As和Hg质量比平均值依次为0.1081、0.0252、0.0812、0.0253、0.0011mg·kg-1,除Pb元素外,其它均低于蔬菜卫生标准。单因子污染指数法评价结果表明,空心菜的Pb元素为轻污染;其它蔬菜各元素为清洁水平。综合污染指数法评价结果显示,辣椒、茄子、豆角、黄瓜、丝瓜和上海青为安全等级;空心菜为警戒线水平。蔬菜重金属THQ(Target Hazard Quotient)均值从大到小依次为:Cr、Pb、Cd、As、Hg,成人和儿童的健康风险指数均小于1,单一重金属对人群健康风险不明显。复合健康风险指数从高到低依次为:上海青、空心菜、辣椒、茄子、豆角、丝瓜和黄瓜。上海青和空心菜对儿童存在健康风险,上海青对成人存在健康风险,其它蔬菜对人群健康风险不明显。食用本地蔬菜摄入的重金属对儿童造成的健康风险高于成人,儿童不宜食用本地产的叶菜类蔬菜,成人慎食。 

     

    Abstract: The concentrations of heavy metals in vegetables collected from Bengbu were measured.The method of single factor pollution index, comprehensive pollution index and target hazard quotient were used to assess pollution levels and food safety of heavy metals in vegetables.The results showed that the average of Pb, Cd, Cr, As and Hg element's concentrations in vegetables were 0.1081, 0.0252, 0.0812, 0.0253 and 0.0011mg·kg-1, respectively, which were lower than the Hygiene standards of vegetables, except Pb element.The single factor pollution index assessment showed that the water convolvulus Pb for light pollution.However, other elements could be regarded as clean levels.The comprehensive pollution index method evaluation, according to the results of pepper, eggplant, long beans, cucumbers, towel gourd and Shanghai green as the safe level. Water convolvulus was warning line level.Vegetables heavy metal company in average from big to small of heavy metals in the order:Cr, Pb, Cd, As, Hg.Adults and children's health risk index was less than 1, the danger of heavey mental on people was not obvious. The compound health risk index from high to low in turn was:Shanghai green, water spinach, pepper, eggplant, long beans, towel gourd, cucumbers, and the children were at the risk of eating Shanghai green and water spinach. For adults, the Shanghai green was also unhealthy, however there were no more danger in eating other vegetables.For children, danger caused by the intake of heavy metals from eating local vegetables was higher than adults.All in all, it's not a advisable way for children to eat local vegetables and adults should choose them carefully.
