目的:调查酱腌菜原料及种植基地污染状况,为从原料上控制酱腌菜安全质量提供依据。方法:对萧山区酱腌菜原料主要产区围垦及10个镇乡的土壤和原料污染物进行网格式采样调查。结果:土壤中重金属及六六六、DDT等污染物指标均符合《无公害蔬菜生产土壤环境质量指标》,东江围垦区土壤As、Hg含量低于其它10个镇,有显著性差异。58件酱腌菜原料(黄瓜、萝卜)重金属和农药指标均符合国家标准,有3件样品污染物含量超过FAO/WHO标准。围垦地区和其它10个镇种植的黄瓜、萝卜污染物含量无显著性差异。结论:萧山区酱腌菜原料毒物残留状况总体较好,但仍应对种植基地采取必要的控制措施。
Objective: To investigate the pollution status of pickles and planting bases in order to provide the basis for controlling the safety quality of pickles from the raw materials. Methods: The main sampling area of pickled vegetable in Xiaoshan district was reclaimed and the soil and raw material contaminants in 10 townships were sampled by grid. Results: The indicators of heavy metals, such as HCH and DDT in soil were in line with “Soil Environmental Quality Indicators for Non-polluted Vegetable Production”. The content of soil As and Hg in the reclamation area of Dongjiang River was lower than the other 10 towns, with significant differences. 58 pieces of pickles raw materials (cucumber, radish) Heavy metals and pesticide indicators are in line with national standards, three samples of pollutant content exceeds the FAO / WHO standards. There was no significant difference in the content of pollutants in cucumber and radish planted in the reclamation area and the other 10 towns. Conclusion: The raw material residues of pickles in Xiaoshan District are generally good, but the necessary control measures should still be taken on the planting base.
