Abstract

A survey of worldwide empirical monitoring data for ACE‐K confirmed its detection in influents, effluents, sludge, and well waters with highest average concentrations in influents 22.9 μg/L and effluents 29.9 μg/L. iSTREEM and E‐FAST probabilistic exposure models using actual ACE‐K usage loadings to the environment to predict ACE‐K concentrations in rivers and streams in the United States confirmed the empirical monitoring data. A regional exposure index was developed that suggests that ACE‐K concentrations in other countries where ACE‐K is used did not exceed 1.39x of North America and therefore the model can be reasonably extrapolated worldwide. Based on conservative predicted no‐effect concentrations (PNEC) estimates and predicted environmental concentrations (PEC) and on an advanced probabilistic risk assessment, safety margins indicate that acesulfame‐potassium (ACE‐K) presents a low risk to the aquatic environment.
