Oseltamivir carboxylate (OC) and Oseltamivir ethylester (OE) were analyzed to evaluate the environmental distribution in pandemic season in Korea. The detected concentration of OE was the range of $0.008\sim0.087\;{\mu}g/L$, and OC was the range of $0.029\sim0.287\;{\mu}g/L$. The detected concentration of OC in this study was two times higher than reported concentration of OC in river water in Japan. But, these analytical results cannot be directly compared to the previous reported concentration, because of the different sampling period.
