Organ-Specific and Size-Dependent Ag Nanoparticle Toxicity in Gills

Organ-Specific and Size-Dependent Ag Nanoparticle Toxicity in Gills - We studied adult zebrafish to determine whether the size of 20 and 110 nm citrate-coated silver nanoparticles (AgC NPs) differentially impact the gills and intestines, known target organs for Ag toxicity in fish. Following exposure for 4 h, 4 days, or 4 days plus a 7 day depuration period, we obtained different toxicokinetic profiles for different particle sizes, as determined by Ag content of the tissues. Ionic AgNO3 served a
