Direct-reading methods for analysis of volatile organic compounds and nanoparticles in workplace air

•Direct-reading methods for air analysis in the workplace.•Direct-reading methods show exposure to volatile organic carbons in workplace air•Direct-reading methods show exposure to nanoparticles in workplace air.•Operating principles, analytical parameters, advantages and limitations of methods.

This review aims to characterize direct-reading methods for analysis of volatile organic compounds (VOCs) and nanoparticles (NPs) in workplace air, in terms of general operating principles, analytical parameters, advantages and limitations. Furthermore, we summarize recent studies using direct-reading methods to assess exposure to VOCs and NPs in workplace air, and comment on future applications and potential research interests within this field.
