Environmental effects According to one study, sucralose is digestible by a number of microorganisms and is broken down once released into the environment. However, measurements by the Swedish Environmental Research Institute have shown that sewage treatment has little effect on sucralose, which is present in wastewater effluents at levels of several μg/L (ppb). No ecotoxicological effects are known at such levels, but the Swedish Environmental Protection Agency warns that a continuous increase in levels may occur if the compound is only slowly degraded in nature. When heated to very high temperatures (over 350 °C or 662 °F) in metal containers, sucralose can produce polychlorinated dibenzo-p-dioxins and other persistent organic pollutants in the resulting smoke.
