Abstract	Alterations in pH have significant effects on nitrification and denitrification processes in aquatic systems. The Jiyun River in northern China experiences significant acid precipitation, and as such was selected to investigate the effects of decreasing pH (river pH at 8.2, pH at 6 and 5) on N dynamics via incubation experiments (35 and 10A degrees C). Statistical results indicated that the NO3 (-) concentrations of the control (pH at 8.2) were either significantly lower (at 35A degrees C) or significantly higher (at 10A degrees C) than the treatments of pH at 6 and 5 at the alpha level of 0.05 in the incubation. However, the NO3 (-) concentrations of the two pH treatments showed significant difference during part of the reaction stage at 35A degrees C and no difference at 10A degrees C. Analysis indicated that nitrification and coupled nitrification-aerobic denitrification occurred for all treatments, which resulted in NO3 (-) being either accumulated or removed at the end of the incubation.
