通过对10种市售水果中6种重金属的检测和分析,发现大连市场主要市售水果中只有铅重金属超标(超标率23.30%),镉和总汞均未超标(GB 2762-2005《食品中污染物限量》中没有总铬、镍及总砷的限量标准)。其中镉重金属的检出率为83.33%,与其余重金属的检出率比较,存在显著性差异。实验结果表明大连市市售水果中铅和镉重金属元素存在潜在的富集性危害。
Through the detection and analysis of six kinds of heavy metals in 10 kinds of commercially available fruits, it was found that only the heavy metals in the main commercially available fruits in Dalian market exceeded the standard (23.30% exceeding the standard), and both cadmium and total mercury did not exceed the standard (GB 2762-2005 Limit of Contaminants ", there is no limit of total chromium, nickel and total arsenic). The detection rate of cadmium and heavy metals was 83.33%, which was significantly different from the detection rate of other heavy metals. The experimental results show that there is a potential enrichment hazard of Pb and Cd heavy metals in commercial fruits in Dalian.
