Effect of transregional transport of pollutants on atmospheric air quality in the Tricity area of Poland

Two-dimensional variance analysis of the results of determination of NO₃⁻, SO₄²⁻, F⁻, Al³⁺, Cl⁻, NH₄⁺,PO₄³⁻, Fe³⁺, Ca²⁺, K⁺ and Mg²⁺, and pH and electrolytic conductivity of precipitation water samples collected in the Tricity area showed that transregional transport of pollutants affects air quality in this region. Over the large area of the Tricity agglomeration fluctuations in analyte concentrations in precipitation water samples are not affected on a statistically significant level by localizing sampling sites, but the area affected by transport direction of air mass movement.
