The study was aimed at the assessment of the effect of the main meteorological elements on suspended particulate matter concentration in Pomerania. The essential material was based on the average diurnal (24 hr period) concentration of suspended total particulate matter (TSP) and dust of isolated grain below 10 μm (PM10) gathered in 1993-2002 at eight municipal measurement stations of the Main Inspectorate for Environmental Protection and on average ten-day period values of nine meteorological elements from the stations of the Institute of Meteorology and Water Management. In the analysed multi-year period of 1993-2002, weather conditions, along with statistically significant trend of immission, accounted for from 9 to 25% of the value of ten-day period concentration of suspended particulate matter in individual months, and 17 to 44% of these values in the calendar seasons of the year. In the complex of meteorological conditions determining the concentration of suspended particulate matter PM10 the largest role was played by the frequency of precipitation expressed by the number of days with diurnal (24 hr period) rainfall of at least 0.5 mm, whereas the role of air temperature and speed of wind was smaller.
