TL;DR: Measurements of the UFP in work environments are, to date, too limited and reported too heterogeneous to allow us to draw general conclusions about workers' exposure, and showed that workers' Exposure to UFP may be significantly higher than their non-occupational exposure to background concentration alone.

TL;DR: Comparison of ND exposure with common pollutants revealed that ND exposure was below 5 μg·m−3, which is one of the proposed exposure limits for diesel particulate matter, and the workers’ calculated dose of NDs during the measurement day was 74 ng which corresponded to 0.02% of the modeled daily (24 h) dose of submicrometer urban air particles.

TL;DR: Based on the results in this study, the analysis of TEM grids seems to be the only direct method to detect single-walled SWCNTs in workplace air.

TL;DR: In this paper, four different engineering control measures were studied in real-life office conditions by means of online NP measurements and indoor aerosol modeling, and the study found that for regular or long-time use of ME desktop 3D printers, the general ventilation is not sufficient control measure for NP emissions, and also the LEV with canopy hood attached above the 3D printer did not control the emission remarkably and successful position of the hood in relation to the nozzle was found challenging.

TL;DR: In this article, the authors measured total VOC (TVOC) concentrations and particle size distributions at three locations representing the various phases of the manufacturing and assembly process of a handcraft workshop producing fishing lures.
