摘　　要：对福州市售不同种类、不同品种、不同批次的28种蔬菜的硝酸盐、亚硝酸盐和维生素C含量分别进行检测,结果表明:福州市售28种蔬菜中亚硝酸盐含量均符合无公害蔬菜质量要求,17种蔬菜的硝酸盐含量符合无公害蔬菜质量要求;4种蔬菜高含维生素C,含量超过56 mg·hg^(-1),6种蔬菜富含维生素C,含量超过20mg·hg^(-1)。综合评价28种蔬菜的硝酸盐和亚硝酸盐含量均符合食品安全国家标准食品中污染物限量要求,其中结球甘蓝、花椰菜和青椒这3种蔬菜的硝酸盐含量低、维生素C含量高,为优质的安全蔬菜。Nitrate,Nitrite and Vc contents of 28 vegetables of different categories,varieties,and/or batches collected from the local vegetable markets in Fuzhou were determined.The analytical results showed that the nitrite contents of all samples and the nitrate contents of 17 vegetables were conform to the quality requirements of pollution-free vegetables.Four vegetables were classified as high-Vc varieties containing more than Vc 56mg·hg^(-1),while 6 were Vc-rich varieties with greater than Vc 20 mg·hg^(-1).Comprehensive evaluation of 28 vegetables were conform to the food pollutants limited requirements in national food safety standards.Among all,the cabbage,cauliflower and green peppers,which showed the lowest nitrate contents and the highest Vc of all tested samples,were deemed to be safe and of high quality varieties for the consumers.
