Different modes of TiO2 uptake by Ceriodaphnia dubia: Relevance to toxicity and bioaccumulation
The extensive environmental exposure of engineered metal oxide nanoparticles (NPs) may
result in their bioaccumulation in aquatic organisms leading to their biotransfer in a food
chain through various routes in a freshwater ecosystem. The present study focuses on the
possible modes of TiO 2 NP trophic transfer to Ceriodaphnia dubia, in presence
and/absence of its diet, Scenedesmus obliquus (primary producer). The acute exposure
studies (48 h) were designed to have daphnids exposed to (i) the free NPs,(ii) both the free …
