ABSTRACT
This is the first comprehensive study on the input, occurrence, and distribution of artificial sweeteners (ASs) in coastal wastewater treatment plants (WWTPs) and their receiving coastal waters. Acesulfame (ACE), aspartame (ASP), cyclamate (CYC), saccharine (SAC), and sucralose (SUC) were monitored for 6â¯months in Cadiz Bay (SW Spain). ASP was always detected at <0.1⯵gâ¯L-1 and removal efficiencies were >90% for SAC and CYC. Higher ACE removal efficiencies were observed during warmer months. Persistence of ACE and SUC was observed in both WWTPs and their receiving coastal surface waters, where values up to 0.6 and 3⯵gâ¯L-1 were measured, respectively. The highest concentrations were measured in a sewage-impacted estuary located in the north of the bay, where conservative behavior was confirmed. The source specificity and recalcitrance of ACE and SUC make them suitable for being used as sewage-pollution markers in coastal environments.
