Abstract

Abstract: We aimed to estimate the dietary exposure level of ethoxyquin (EQ) and its main metabolite ethoxyquin dimer (EQDM) in 6 kinds of farmed aquatic animals based on the residues and aquatic animal consumption data from Korea. The residues were measured in 143 aquatic animal samples by LC-MS/MS. The dietary exposure level was estimated under four scenarios based on the WHO guidelines. The residue concentrations of EQ and EQDM were in the ranges of 0.14–24.2 and 0.1–315 μg/kg, respectively. The sum of aquatic animal consumption for six aquatic animals was 6.38 g/day (whole group) and 372 g/day (consumer only) in the national food consumption survey. Based on our results, there is no significant risk resulting from EQ and EQDM exposure of humans under all scenarios. This is the first study to present the residue concentrations and exposure levels of EQ and EQDM in farmed aquatic animals in Korea. Highlights: We measured EQ and EQDM in 143 aquatic animal samples from Korea. The association between the EQ and EQDM residues in farmed aquatic animals. The residue concentrations of EQ and EQDM varied with fish species. Aquatic animals are highly exposed to EQ via fish meal. The current exposure level of EQ and EQDM did not pose a significant risk.
