摘要: Abstract Natural surface waters are threatened globally by antibiotics pollution. In this study, we analyzed and CDOM (Chromophoric dissolved organic matter) fluorescence in different water bodies using HPLC method Excitation Emission Matrix- Parallel factor analysis, respectively. A combination of field studies the Yinma River Watershed were conducted rivers, reservoirs urban 65 antibiotic samples taken April, May, July, August 2016. EEM-PARAFAC analysis identified two components; a humic-like (C1) component tryptophan-like (C2) component. The redundancy (RDA) demonstrated that could explain 38.2% (two axes) five (N = 31), 26.0% those rivers (N = 30). Furthermore, Pearson correlation coefficient between Sulfamethoxazole C1 reservoir was 0.91 (t-test, 2-tailed, p
