Abstract
Silver nanoparticles (AgNPs) are applied in many products as antimicrobial agents and can be found in the environment. In this study, the uptake and elimination kinetics of silver nanoparticles in fish (Carassius auratus), via simultaneous water and dietary exposure, was investigated and compared with ionic silver (AgNO3). Silver concentration in the tissues of C. auratus after the uptake phase was similar between nanoparticles and ionic treatments. Upon exposure to nanoparticles, Ag concentration in the different tissues of C. auratus was significantly different (Ag[liver] > Ag[intestine] > Ag[gill] > Ag[muscle]). The liver presented the highest amount of Ag among all organs, and no elimination was detected throughout the elimination period. Our results suggest that once uptake of Ag occurs in fish, the elimination takes very long which may pose ecological implications for bioaccumulation.
