• Description:
  We present a multi-tiered methodology designed to thoroughly characterize the engineered nanomaterials (ENMs) released from nano-enabled toners during printing. A printer exposure generation system (PEGS) suitable for the physico-chemical and toxicological assessment of printer-emitted particles (PEPs) was developed to screen commercially available laser printers. Results from our extensive analysis show laser printers emitted nanoparticles at concentrations of up to 1.3 million particles/cm3. Moreover, toner powders and PEPs share a similar chemical composition (organic, metal, metal oxides). Toxicological assessment using in vitro and in vivo models showed PEPs have the potential to be biologically reactive (e.g., inflammation, cytotoxicity, epigenetic modifications). Overall, our results suggest that laser printer emissions are chemically complex and bioactive and thus, may be deleterious to the physiology of individuals exposed to these particles both in a residential and occupational setting.
