Table 1

Comparison of the average concentration of air pollution in the years 2015-2016 in the Pomeranian Voivodeship in Poland with the criteria used by the EU and WHO.

	Mean annual concentration of SO2 (μg/m^3)	Mean annual concentration of NO2 (μg/m^3)	Mean annual concentration of NOx (μg/m^3)	Mean 8-h concentration of CO (μg/m^3)	Mean annual concentration of PM10 (μg/m^3)	Mean 24-hour concentration of PM10 (μg/m^3)
Pomeranian Voivodeship	4	15	21	374	22	92
Acceptable concentration of pollutants (μg/m^3) acc. to the EU	20	40	30	10.000	40	50
Acceptable concentration of pollutants (μg/m^3) acc. to WHO	50	40	—	10.000	20	50

Abbreviations: EU: European Union; WHO: World Health Organization; SO₂: sulphur dioxide; NO₂: nitrogen dioxide; NOx: nitric oxide; CO: carbon monoxide; PM₁₀: particulate matter 10 micrometers or less in diameter; not to be exceeded on more than 35 days per year 99th percentile 3 day/year.
