Bioavailability of lead and lead-halide perovskite nanoparticles in zebrafish

The aim of the study was to investigate aqueous and dietary toxicity of Pb-halide perovskite nanoparticles (NPs) and Pb in zebrafish. Perovskite NP toxicity was evaluated by assessing mortality and gene expression (metallothionein 2 and δ-aminolevulinic acid dehydratase). Zebrafish larvae were exposed to Pb-halide perovskite NPs in parallel with Pb(NO3)2 exposures in the aqueous phase and zebrafish adults were exposed through diet by Pb and perovskite NP-spiked food pellets. The dataset includes mortality and gene expression data in addition to analytical chemistry data regarding the Pb content in exposure media and food pellets.
