Summary
The assessment of the impact chosen meteorological parameters on the concentrations of particulate matter (PM10) and it contains heavy metals at the level of regional background in North-Eastern Poland was the aim of research. Analysis of data based on the results of the measurements carried out on the Puszcza Borecka Station of Institute of Environmental Protection – National Research Institute in the years 2005–2011. The calculated coefficients of determination are presented in terms of seasonal and annual basis. Presented analyzes showed that most factors contributing to the decrease in the PM10 concentration in the colder half of the year are growth of height and duration of precipitation and increase in wind speed. In the warm season, the intensity of the precipitation, the air temperature and the intensity of the solar radiation play most important rule. Effects of meteorological conditions on concentration of heavy metals is varied. Referring to the highest concentrations of metals (zinc, lead and arsenic), it can be concluded that in the colder half of the year the factors contributing most to their decrease concentrations are increase air temperature, increase irradiance and decrease relative humidity of the air. In the warm half of the year, the increase in intensity of solar radiation and precipitation, air temperature and decrease relative humidity air contributes the most to the decline concentration of most heavy metals contained in PM10 particulate matter. Effect of wind speed and air pressure on the concentration of heavy metals in PM10 proved to be the smallest.
