Abstract
Sucralose an intense artificial sweetener has been detected in wastewater and surface waters at concentrations ranging from ng/L to low µg/L Although over a hundred studies have been conducted to evaluate the safety of sucralose for human consumption few studies have focused on the chronic ecotoxicological effects of this compound in fish As a remedy to this data gap an earlylife stage toxicity test was conducted to assess the effects of sucralose on hatching survival and growth of fathead minnows Pimephales promelas Hatching survival and growth were unaffected by 98 mg/L of sucralose The LowestObservedEffect Concentration LOEC and the NoObservedEffect Concentration NOEC for fathead minnows determined by this study are 98 and 98 mg/L respectively The results from this study suggest that the concentrations of sucralose detected in the environment are well below those required to cause adverse effects to developing aquatic organisms
