Abstract:BackgroundDue to the rapid development of the powder-coating process and growing awareness of occupational health, the ultrafine particles (UFPs) generated during the powder-coating process have become a serious and urgent problem. However, researchers have not clearly understood the risk of exposure to the UFPs and inhalation risk of the UFPs. ResultsIrregularly shaped, aggregating particles containing Si, Al, Fe, Mg, Pt, and Ca elements were sampled from the work area. The number concentration (NC), mass con… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
