Editors’ Choice: Effects of intratracheally instilled laser printer-emitted engineered nanoparticles in a mouse model: A case study of toxicological implications from nanomaterials released during consumer use

Editors´motivation for choosing this paper

The research presented here is ground breaking since it aims to understand the potential adverse effects in human health that could stem from exposure to emissions from such a popular nano-enabled product (i.e., laser printers).

Exposure to engineered nanoparticles released from nano-enabled toners during printing (called laser printer-emitted particles or PEPs) might lead to immune responses as well as modifications in gene expression in the murine lung when exposure occurs at doses comparable to real world exposure scenarios, pointing to potential health implications both at the occupational but also at the consumer level.
