塑料中铅、镉、铬、汞四种重金属遴选设立的研究

摘要

By comparing the limits of heavy metals in plastics regulated in the mandatory standards of domestic and foreign laws and regulations,including arsenic,lead,mercury,chromium and cadmium,and through studying the influence of these heavy metals on infants and pregnant women,the limit reference value of lead,cadmium,hexavalent chromium and mercury in plastic materials was formed to provide technical support for the determination of the contents of lead,cadmium,hexavalent chromium and mercury in infant products,food contact plastic products,pharmaceutical packaging materials,daily-used plastic products and other industrial plastics materials.%通过比较研究国内外法律、法规强制性标准对各种塑料中的砷、铅、铬、镉等四种重金属限定值及这四种重金属对孕妇和婴幼儿的影响,形成塑料材料中铅、镉、六价铬、汞限量参考数值,为婴幼儿制品、食品接触塑料制品、药品包装材料、日用塑料制品及其他工业塑料材料中铅、镉、六价铬、汞含量的测定提供技术保障.
