Fig. 1From: Influence of citrate and PEG coatings on the bioaccumulation of TiO2 and CeO2 nanoparticles following dietary exposure in rainbow troutLevels of Ti (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) TiO2 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). No letters appear in the depuration phase due to a lack of any significant differences between treatmentsBack to article page
