In this work, two groups of experiments have been done by using mice and luminous bac-teria. The resnlts show that there exists an antagonism in toxicity between selenium andhumic acid (HA) extracted from the drinking water in Kaschin Beck disease regions. In order tostudy the chemical mechanism of the antagonism, gel filtration and X-ray photoelectron spec-troscopy techniques have been used to study the chemical bonding of the synthetic HA-Se insolution. The relationship between Se and HA in the cause of Kaschin Beck disease isdiscussed.
