Geochemical Character of Selenium Fluorine and Human Health

摘要

The abundance characteristics of selenium and fluorine in stream sediments, soils, shallow underground water, grain and human hair are studied across China. It shows that some environmental factors such as Eh, pH and the element composition of rocks affect the migration and distribution of fluorine and selenium. And we come to tlv conclusion that there is a relationship between some diseases such as Keshan disease, Kashin-bi'ck disease and liver cancer disease and the combination of elements such as Se, F, etc.
