摘要:

Alarm has been heightened internationally in recent years to control the contents of metals such as Cd, Pb, As and Hg and other toxic contaminants in CM products. Among these elements, mercury is receiving more attrition not only because of contamination, but also because of its use often as an active CM ingredient. The quality, efficacy, and safety of CM products related to these elements have to be critically assessed before the products can be put in clinical trials or placed on the market. It is now well recognized the mercury is a toxic element, regardless of inorganic or organic species. The toxicity of mercury depends on both its concentration and chemical forms. Because of the great differences in toxicity and bioavailability between organic/inorganic and the other chemical forms of mercury, there is a strong need to develop analytical methodologies for mercury speciation analysis.
