Journal ArticleDOI
Vacuum cleaner emissions as a source of indoor exposure to airborne particles and bacteria
TL;DR: Vacuuming can be a source of indoor exposure to biological and nonbiological aerosols, although there are few data that describe the magnitude of emissions from the vacuum cleaner itself, and this may vary markedly depending on the vacuum used.
Journal ArticleDOI
JEM Spotlight: Environmental monitoring of airborne nanoparticles
Lidia Morawska,Hao Wang,Zoran Ristovski,E.R. Jayaratne,Graham R. Johnson,Hing Cho Cheung,Xuan Ling,Congrong He +7 more
TL;DR: The aim of this work was to review the existing instrumental methods to monitor airborne nanoparticles in different types of indoor and outdoor environments in order to detect their presence and to characterise their properties.
Journal ArticleDOI
Ozone-Initiated Particle Formation, Particle Aging, and Precursors in a Laser Printer
TL;DR: This study significantly improved scientific understanding of the formation mechanisms of printer-generated particles, and highlighted the possible SOA formation potential of unsaturated nonterpene organic compounds by ozone-initiated reactions in the indoor environment.
Journal ArticleDOI
Quantification of the relationship between fuser roller temperature and laser printer emissions
Congrong He,Lidia Morawska,Hao Wang,Rohan Jayaratne,Peter McGarry,Graham R. Johnson,Thor E. Bostrom,Julien Gonthier,Stephane Authemayou,Godwin A. Ayoko +9 more
TL;DR: In this article, the authors measured emissions from 30 laser printers in chamber using a standardized printing sequence, as well as monitoring fuser roller temperature, and found that almost all printers were high particle number emitters (i.e. > 1.01×1010 particles/min).
Journal ArticleDOI
Identification of technical problems affecting performance of DustTrak DRX aerosol monitors.

TL;DR: In this article, the authors report on issues that have arisen from the use of the latest generation models DustTrak DRX (8533 and 8534) in the BREATHE, UPTECH and IMPROVE projects that can compromise data quality.
