<abstract>
<p>The impact of road dust emissions on PM&lt;sub&gt;10&lt;/sub&gt; and PM&lt;sub&gt;2.5&lt;/sub&gt; (atmospheric particulate matter with diameteer &lt; 10 μm and 2.5 μm mass concentrations
recorded from 2003 to 2010 at 11 locations (rural, urban and industrial) in
southern Spain was estimated based on the chemical characterization of PM
and the use of a constrained Positive Matrix Factorization, where the
chemical profile of local road dust samples is used as a priori knowledge.
Results indicate that road dust increased PM&lt;sub&gt;10&lt;/sub&gt; levels on average by
21–35% at traffic sites, 29–34% at urban background sites heavily
affected by road traffic emissions, 17–22% at urban-industrial sites and
9–22% at rural sites. Road dust contributions to ambient PM levels show a
marked seasonality with maxima in summer and minima in winter, likely due to
the rainfall frequency. Decreasing concentration trends over the sampling
years were found at some traffic and urban sites but in most cases the decreases were less
significant than for vehicle exhaust emissions, while concentrations
increased at industrial sites, probably due to local peculiarities.
Concerning PM&lt;sub&gt;2.5&lt;/sub&gt;, road dust contributions were lower than in PM&lt;sub&gt;10&lt;/sub&gt;, as
expected but still important (21–31%, 11–31%, 6–16% and 7% for
traffic, urban background, urban-industrial and rural sites, respectively).
In addition the three main sources of road dust (carbonaceous particles,
brake wear and road wear/mineral) were identified and their contributions to
road dust mass loadings estimated, supporting the idea that air quality managers should drive
measures aimed at preventing the build-up of road dust particles on roads.</p>
