Dust kicked up by vehicles traveling on [[road]]s is a significant source of harmful [[air pollution]].<ref>{{cite journal |last1=Khan |first1=Raihan K. |last2=Strand |first2=Mark A. |title=Road dust and its effect on human health: a literature review |journal=Epidemiology and Health |date=10 April 2018 |volume=40 |pages=e2018013 |doi=10.4178/epih.e2018013 |pmid=29642653 |pmc=5968206 |issn=2092-7193}}</ref> Road dust consists of deposits of vehicle and industrial [[exhaust gas]], particles from [[tire]] and [[brake]] wear, [[construction dust|dust]] from paved roads or [[pothole]]s, and dust from [[construction]] sites. Road dust is a significant contributor to the generation and release of [[particulates]] into the atmosphere.<ref>{{cite web|date=September 23, 2006|title=Environment Canada – Pollution and Waste – Tracking Pollution in Canada|url=http://www.ec.gc.ca/pdb/npri/consultations/2006/Road_Dust_e.cfm|url-status=dead|archive-url=https://web.archive.org/web/20060924014341/http://www.ec.gc.ca/pdb/npri/consultations/2006/Road_Dust_e.cfm|archive-date=September 24, 2006|access-date=May 17, 2021|website=The Green Lane}}</ref> Control of road dust is a significant challenge in [[urban area]]s, and also in other locations with high levels of vehicular traffic upon unsealed roads, such as mines and [[landfill]]s.

"Engine exhaust emissions, especially from those operating on diesel fuel, can be a significant source of fine particle generation from construction sites." Construction and [[demolition]] activities can also produce a large amount of [[construction waste]]. The dust and [[particulates]] can become [[fugitive dust| fugitive]] and airborne with [[vehicle]] movements both on and outside the sites, especially when it is windy and dry.<ref name=rbkcgovuk>{{cite web | url=https://www.rbkc.gov.uk/pdf/Document%2012%20-%20BRE%20-%20Control%20of%20Dust%20from%20Construction%20&%20Demolition%20Activities.pdf | title=Control of dust from construction and demolition activities | page=12-22 |  access-date=4 Feb 2025}}</ref>
