Effect biomarkers of nanoparticle-exposed workers: A scoping review

Research output: Contribution to journalReview articlepeer-review


The widespread and increasing use of engineered nanomaterials (i.e., particulate materials measuring 1–100 nanometers (nm) in at least one dimension) poses a potential health and safety risk to exposed workers. The unique properties of nanomaterials have made nanomaterials useful in multiple industries. However, their production and use may compromise worker health, presenting an emerging occupational health hazard, the acute and chronic effects of which have not been fully assessed. In this scoping review, we critically assess the literature on biomarkers of effect from nanoparticles and discuss the utility of biomonitoring as a means of assessing the physiological effects of nanoparticle exposure among nanotechnology workers. Multiple databases were queried based on select inclusion and exclusion criteria according to PRISMA guidelines, and articles were independently screened by two topic experts. Of 286 articles initially retrieved, 28 were included after screening and eligibility. The reviewed articles indicated that sensitive effect biomarkers could reflect early health effects of exposure to nanoparticles in the workplace and may be useful for monitoring toxicological effects and associated risks.
