摘要: Abstract The study of the bioconcentration silver nanoparticles (AgNPs) is important to fully understand their hazard potential in aquatic environment. We synthesized AgNPs radiolabeled with isotopes (110mAg) quantify coated citrate (AgNPs-CIT) and polyvinylpyrrolidone (AgNPs-PVP) Japanese medaka, investigate biodistribution organs, which were compared 110mAgNO3. BCF values determined be 39.8 ± 7.4, 42.5 ± 5.1 116.4 ± 6.1 L kg−1 for AgNPs-CIT, AgNPs-PVP AgNO3, respectively. release more ions contributed a different kinetic uptake pattern was similar that AgNO3. Bioconcentrated medaka not observed eliminated, independent surface coating differences, similarly There no difference each organ before after depuration two types all mainly concentrated liver. This quantified distribution AgNO3 precisely by utilizing isotope, helpful monitoring toxicity medaka.
