ABSTRACT
Saint Petersburg residents often consider the city as rather dusty. Corresponding nuisances andaesthetic damage are extremely negatively perceived. Current paper analyses the state of particulate matter (PM) pollution in Saint Petersburg based on five-year data on dust concentrations. To revel the possible contribution of auto transport to dust pollution we use also nitrogen dioxide concentration data at the same monitoring stations. It was obtained that dust levels in residential areas are generally higher than in the city center. Approximate analysis permits to suggest that monitoring stations register PM concentrations of the size up to 70-100 μm with about 30-40 % of PM10. Probably the main contribution comes from fugitive dust from the surface, which creates the impression of a dusty environment.
