Determination of Artificial Sweeteners in Waste Water and their Potential Impact on the Ecosystem

Popis výsledku v původním jazyce

In our work we aimed on the determination of selected artificial sweeteners (saccharin (SAC), cyclamate (CYC), acesulfame-K (ACE) and sucralose (SUC)) in waste water and on their ecotoxicological evaluation. Above mentioned AS were selected because as artificial compounds there are not transformed completely in the human or animal body and enter waste water unchanged; in addition some of them (namely ACE, SUC) are removed to a very limited extent in wastewater treatment plants (WWTPs) and then entered water ecosystem and are detected in surface water. The 24-hour composite samples (at influent and effluent) were collected at the WWTP Brno-Modřice (capacity 513,000 PE) using an automatic sampler with a sampling interval of 2 hours. Analysis of AS via liquid chromatography with mass spectrometry, using solid phase extraction was carried out. At the inflow of the WWTP, concentration of all monitored sweeteners ranged between 1.40 to 22.67 μg.L-1. At outflow only saccharin at very low concentration (avera
