目前通常用某种重金属在血液或尿液中的含量作为该金属中毒诊断的参考指标。但这些指标在实际应用中都存在一些问题。近些年来,人们为找到一项既安全方便又能反映金属在体内含量的指标做了大量的工作。生理学研究证明,唾液腺是人体的排泄器

However, these indicators have some problems in practical application. In recent years, a great deal of work has been done to find an index that is both safe and convenient and can reflect the content of metal in the body.
