玩具婴童用品中特定元素人体环境迁移试验条件综述

Review on Migration Test Condition for Certain Elements in Human Body Environment

玩具婴童用品材料中的特定元素在玩耍或使用过程会向人体迁移,对儿童健康产生潜在的危害,国内外许多国家已制定相关法规限制其可迁移含量。该文综述了特定元素的人体暴露途径和迁移模型,结合儿童生理特征分别对汗液迁移、唾液迁移和胃液迁移3种模拟迁移试验的关键技术参数进行了详细介绍,对国内外差异进行了总结,并对其研究发展趋势进行了展望,可为建立玩具婴童用品材料中特定元素迁移试验通则提供参考。

Toys or juvenile products pose potential risks to children s health when being played,as certain elements could migrate to human bodies.The migration levels have been restricted by regulations in either China or many other countries.The exposure way and migration model of certain elements have been reviewed in this paper.The key technical parameters for three simulated migration experiments including sweat migration,saliva migration and gastric juice migration have been respectively introduced in detail and in consideration of physiological characteristics of children.Meanwhile,the differences of migration models between China and other countries have been summarized,and an outlook is made on their tendency of future development,which could provide a reference for the development of general rules for migration experiment of certain elements in toys and juvenile products.
