Levels of Ce (mean ± SEM) measured in the a stomach (n = 8), b intestine (n = 8) and c carcass (n = 5) of rainbow trout fed control diets and diets spiked with uncoated (UNC), citrate coated (CIT) and polyethylene glycol coated (PEG) CeO2 NPs (100 mg NPs/kg feed) following a 10-day exposure period and throughout a depuration phase (days 11–52). Dashed line indicates end of the exposure (uptake) phase and start of depuration. Letters have been used to indicate significant differences between treatment groups, with bars bearing distinct letters significantly different from each other (ANOVA followed by Holm–Sidak pairwise comparison; p < 0.05)
