Abstract
Urban areas represent the main zones of anthropogenic emissions and, at the same time, includes the largest number of
population exposed to air pollution. Data related to traffic hot spots locations in Sibiu urban areas are presented and discussed in
this paper. It is important to assess the impact of changing climate conditions and concentration of pollutants, these aspects are of
special interest because of high and increasing population of urban regions exposed to consequences of climate change and air
pollution. Paper tackling the problem of traffic related pollution and especially PM10 fraction as a novel research. No other
research were previously done in Sibiu region emphasising particulate matter generated by traffic, and the importance of the
research is more obvious considering the new infrastructure and growing number of transition traffic in the region. Measurements
were conducted within Environmental Agency of Sibiu team and are presented and discussed with regard to the updated
situation.
