Usingthis method, the GSH content of Rana nigromaculata tadpoles under different concentrationsof Na2SeO4 and Na2SeO3 were measured. The induce of selenate to the content of GSH intadpoles makes its variation has well time-effect and dose-effect relationship. Thesephenomena demonstrate that GSH is smart to the exposure of selenate, and therefore can beused as a sensitive index to selenate pollution.
