Abstract

Artificial sweeteners (ASs) are applied widely as sucrose substitutes in food, pharmaceuticals, and personal-care products, which results in their release into surface water. The occurrence of ASs in aquatic environments in China has rarely been reported. In this study, we determined the concentration of seven ASs in surface water and sediment samples from 16 lakes in Wuhan. The sum of the ASs concentration ranged from 0.89 to 20.6 μg/L in the surface water, with a mean value of 4.96 ± 5.16 μg/L. The most abundant AS was sucralose (SUC), with a concentration from 0.33 to 18.0 μg/L, followed by acesulfame (ACE) (0.40-2.78 μg/L), saccharin (SAC) (MDL to 1.86 μg/L), and cyclamate (CYC) (MDL to 2.22 μg/L). SUC and ACE accounted for 90% ± 8% of the total ASs in the surface water. The Σ
