A, B Pearson correlation coefficients (r) of linear fits between river DO and ammonium (NH4+-N), and between DO%sat and NH4+-N in the 1156 rivers in China. White circles show non-significant results (p > 0.05). Inserted are examples of site-specific relationships (colored dots map to locations). C, D Corresponding relationships between river DO and chemical oxygen demand (COD), and between DO%sat and COD in the 1156 rivers in China. Relationships between DO and COD, and between DO%sat and COD, with example sites shown.
