Adsorption and desorption of selenium in peat soil were studied using an isothermal adsorption approach to investigate the effect of soil Eh, pH and organic matter(O.M.) on Se availability in Kashin-Beck Disease-endemic area, Ruoergai county, Sichuan, China. Results showed that the adsorbing capacity of reduction state soil for SeO₃^2--Se was more than that of oxidation state soil, the desorbing capacity of water-solubility selenium (W-Se) and exchangeable selenium (E-Se) was higher in oxidation state than that in reduction state, but on the contrary was the that of latent available selenium (LA-Se). Soil oxidation state was helpful to improve the availability of soil Se. With the raising of pH value, the adsorbing capacity for SeO₃^2--Se decreased, the desorbing capacity of W-Se increased and that of E-Se decreased, but the desorbing capacity change of LA-Se was not obvious. Soil organic matter adsorbed Se in large quantities and weakened the availability of soil Se, the adsorbing capacity for SeO₃^2--Se reduced greatly, the amount of W-Se and E-Se enhanced and that of LA-Se diminished obviously after getting rid of soil organic matters. Lower availability of soil Se due to high content of organic matter and strong soil reduction circumstances was probably an important reason of Se deficiency to humans and domestic animals in Kashin-Beck Disease endemic area, Ruoergai county, Sichuan, China.
