Abstract：Water quality criteria form scientific basis of water quality standard. It has been urgent to establish water quality standard in China based on water quality criteria studied according to situations of Chinese species distribution and water quality characteristics. Acute and chronic criteria functions with two arguments of temperature and pH for ammonia in Liao River basin were derived according to the U.S. guidelines. The acute and chronic criteria for ammonia in Liao River basin were 3.06 and 0.364 mg/L, respectively, with the parameter of pH 8.0 and 25℃. Two methods of criteria development in Dutch and Australia were also used to derive the ammonia criteria, respectively, and the results were compared with that of the U.S. method. It suggested that the criteria derived by these three methods were of the same order of magnitude, while the Dutch method was relatively conservative. In addition, the derived criteria were tentatively transformed to lash-up standards.
