The artificial sweetener sucralose has been detected in municipal wastewater effluent and surface waters at concentrations ranging from ng/L to low mu g/L. Few chronic ecotoxicological data are available in the peer reviewed literature with respect to sucralose. To address this data gap, 21 d Daphnia magna and 28 d Americamysis bahia (mysid shrimp) studies were conducted to assess the effects of sucralose on the survival, growth and reproduction of these organisms. Concentrations <= 1800 mg/L resulted in no statistically significant reduction in D. magna survival or reproduction. Survival, growth and reproduction of mysid shrimp were unaffected by <= 93 mg/L sucralose. The no observable effect concentration (NOEC) and lowest observable effect concentration (LOEC) for the D. magna study were 1800 and >1800 mg/L, respectively. The NOEC and LOEC for the mysid study were 93 and >93 mg/L, respectively. Collectively, these data suggest that the concentrations of sucralose detected in the environment are well below those required to elicit chronic effects in freshwater or marine invertebrates.
