Measurements of Sucralose in the Swedish Screening Program 2007 -PART I; Sucralose in surface waters and STP samples.

IVL has performed a 'screening study' of sucralose on commission from the Swedish EPA. Sucralose is a chlorine containing derivative of sucrose, manufactured by selectively substituting three hydroxyls with chlorine. The substance is used as a sweetener in food products; on a weight basis it tastes ca. 600 times sweeter than the parent compound. The objectives of the study were to determine the concentrations of sucralose in media in the Swedish environment related to wastewater effluents and to highlight important transport pathways. In total 57 samples were analysed representing wastewater and sludge from sewage treatment plants as well as surface waters.
