Monitoring and Analysis of 26 Elements in Allium mongolicum in Ordos
Objective:To monitor the content of 26 elements in Allium mongolicum(including fresh and pickled samples)in Ordos city,and to provide a basis for risk monitoring and the formulation of relevant standards.Method:According to GB 5009.268-2016,the contents of 26 elements in 30 fresh and 60 pickled samples of Allium mongolicum were determined by inductively coupled plasma mass spectrometry,and the results were statistically analyzed.Result:All 26 elements were detected in all Allium mongolicum.The pass rate of lead in fresh Allium mongolicum was 93.4%,98.3%in pickled Allium mongolicum,78.3%in sodium in pickled Allium mongolicum,100.0%for cadmium,chromium,arsenic and mercury,and there was no limit standard for the rest of the elements.The average contents of potassium,calcium,magnesium and iron in pickled Allium mongolicum were lower than those in fresh Allium mongolicum,and the average sodium content in pickled Allium mongolicum was significantly higher than that in fresh Allium mongolicum.Conclusion:Cadmium,chromium,arsenic and mercury in Allium mongolicum were not polluted,but the monitoring and early warning of lead in Allium mongolicum should be improved,the sodium in pickled Allium mongolicum was in the warning line-moderate pollution,and the contents of potassium,calcium,magnesium and iron in pickled Allium mongolicum were easy to be lost,so the intake of pickled foods should be controlled in daily diet.
