Sažetak
Climate change may affect local air quality by altering the emission, dispersion, chemical transformation and deposition
of air pollutants. This study evaluates the effects of climate change in a real-life mixed land-use situation where there are adjacent
urban and industrial activities and also fugitive emissions from stockpiles and unpaved roads. For this example we show how windspeed
and time-of-day dependent ‘bi-polar plots’ created from ambient monitoring data can be used to learn more about the nature
of sources responsible for exceedances of particulate matter air quality standards, and hence to assess how sensitive their impacts
are to climate change. Unpaved roads and wind-blown fugitive sources such as stockpiles and coal handling beds in the industrial
area appear to contribute substantially to raised air-quality impacts. The effect of climate change on impacts from these sources may
differ from its effect on impacts from conventional combustion sources.
