Temporal and seasonal variations of black carbon (BC) in a highly polluted Eastern European city: Apportionment of potential sources and the effect of meteorological conditions.

Popis výsledku v původním jazyce

The temporal and seasonal variations of black carbon (BC) concentrations were evaluated during a three-year measurement period. The data were collected at a residential site of a highly polluted Eastern European city - Ostrava, located in the Czech Republic and surrounded by major highways as well as large industries. Significantly higher BC concentrations were obtained in Ostrava, relative to other European cities. The magnitude of BC concentration in Ostrava was equivalent to the magnitude of BC concentrations measured in Poland and in megacity in China. The data were categorized to heating and non-heating seasons based on the periodic pattern of daily and monthly average concentrations of BC. A higher BC concentration was obtained during heating season than non-heating season and was primarily associated with an increase in residential coal burning and meteorological parameters. The concentration of BC was found to be negatively correlated with temperature and wind speed, and positively correlated with the relative humidity. Other BC sources potentially included emissions from vehicle exhaust and the local steel-producing industry.
