Levels of Ti (mean ± SEM) measured in the a liver (n = 3) and b gill (n = 3) of rainbow trout fed control diets and diets spiked with uncoated (UNC), citrate coated (CIT) and polyethylene glycol-coated (PEG) TiO2 NPs (100 mg NPs/kg feed) following a 10-day exposure period and following 42 days of depuration (day 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). Tissues samples at days 11, 17, 24 and 38 were not taken
