ICP-MS法检测食用盐中重金属污染的研究

Research on the Detection of Heavy Metal Pollution in Edible Salt by ICP-MS Method

本研究利用电感耦合等离子体质谱(Inductively Coupled Plasma-Mass Spectrometry,ICP-MS)方法检测不同类型和产地市售食用盐中的重金属含量,评估其潜在的健康风险,并为相关部门完善食用盐质量标准和实施更加严格的食品安全监管措施提供科学依据。结果表明,13个样本中,岩盐和海盐的重金属含量普遍高于精制盐。值得注意的是,部分高污染地区的食盐产品重金属含量接近安全限值。对此,建议加强生产源头监管、优化加工工艺、加强定期检测与市场抽检以及加强公众教育和消费引导,以确保消费者健康安全。

In this study,inductively coupled plasma mass spectrometry(ICP-MS)is used to determine the content of heavy metals in different types and origins of commercially available food salt to assess their potential health risks,which can provide scientific basis for relevant departments to improve the quality standards of edible salt and implement more stringent food safety supervision measures.The results show that the heavy metal content of rock salt and sea salt is higher than that of refined salt.It is worth noting that the heavy metal content of salt products in some highly polluted areas is close to the safety limit.In this regard,it is recommended to strengthen the supervision of the production source,optimize the processing technology,strengthen regular testing and market sampling,and strengthen public education and consumption guidance to ensure the health and safety of consumers.
