Abstract

The development of civilization has a significant impact on the increment in environmental pollution. Particular threats to the health of people living in urban agglomerations make the unfavourable changes in atmospheric air.

The aim of this study was to describe the influence of climate (seasons, annual temperature changes) and presence of sources of air pollutants emissions on air pollutants concentrations in the selected urban agglomeration - Szczecin (Poland).

Researches were conducted at 4 air pollution monitoring stations during the period 2005-2008.

There were noticed statistically significant relationships between the air pollutants concentrations and climate parameters (wind, temperature, seasons). It was found that average annual PM10 concentrations were lower than the limit value. By contrast average daily PM10 concentrations exceed quality standards. Annual average concentrations of lead and cadmium in PM10 were lower than acceptable levels (for lead) or destination levels (for cadmium). While the average concentrations of benzo(a)pyrene in PM10 were above the target value - 1ng/m³. The air quality in Szczecin agglomeration improved during the period 2005-2008.
