Evaluation of toxicity of polystyrene microplastics under realistic exposure levels in human vascular endothelial EA.hy926 cells.

Microplastics (MPs) have emerged as a global concern, with a recent study being the first to detect them in the bloodstream of healthy people. However, precise information regarding the toxic effects of MPs on the human vascular system is currently lacking. In this study, we used human vascular endothelial EA.

Comparative pulmonary toxicity assessment of tungsten trioxide and tungsten trioxide hydrate nanoparticles.

Tungsten trioxide (WO)-based nanoparticles (NPs) are gaining popularity because of their exciting potential for photocatalytic applications; however, the toxic potential of WO-based NPs remains a concern. In this study, we evaluated the toxic risk of WO NPs and hydrated WO NPs (WO·HO NPs) using lung cells and explored the underlying mechanism. WO NPs and WO·HO NPs significantly decreased the number of viable cells (59.
