Distribution of silver nanoparticles in pregnant mice and developing embryos.

abstract：:Engineered nanoparticles are increasingly discharged into the environment. After discharge, these nanoparticles can interact with co-existing organic contaminants, resulting in a phenomena referred to as 'joint toxicity'. This study evaluated joint toxicities of TiO2 nanoparticles (TiO2NPs) with four different (atrazi...
