Abstract

）. The proportions of sulfonamide and quinolone antibiotics in individual lakes and reservoirs ranged from 2.6%-80% and 0.8%-36%， respectively. Sulfaguanidine and acetaminophen exhibited high ecological risks， and acetylsalicylic acid， ofloxacin， and sulfadiazine were categorized as medium-risk compounds. The distribution and characteristics of pharmaceutical emerging contaminants in lake and reservoir sediments were significantly influenced by regional anthropogenic activities， with primary industry， livestock farming， aquaculture， and population size having substantial impacts on their spatial distribution.
