Noticeable improvement. Lower concentration of pollutants compared to last year
The air quality in 2023 has improved significantly compared to the previous year. The concentrations of most pollutants were lower - reported the Chief Inspectorate of Environmental Protection.
The Chief Inspector of Environmental Protection (GIEP) carried out an air quality assessment for 2023 and based it on the classification of zones for each substance separately, according to criteria defined in terms of human health and plant protection. The results of the classification of 46 assessed zones were included in the provincial air quality assessment reports for 2023 - said the Chief Inspectorate of Environmental Protection.
The assessment for the protection of human health was performed for 12 pollutants: sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3), benzene (C6H6), suspended dust PM10, suspended dust PM2.5 and pollutants determined in PM10 dust: benzo(a)pyrene (B(a)P), arsenic (As), cadmium (Cd), nickel (Ni) and lead (Pb).
The assessment for plant protection was performed for three pollutants: sulfur dioxide (SO2), nitrogen oxides (NOX) and ozone (O3).
The air quality assessment for 2023 showed a significant improvement in quality compared to 2022. The concentrations of most pollutants were lower than in 2022, and the areas where the exceedances occurred were also reduced - informed the Chief Inspectorate of Environmental Protection.
In 2023, exceedances of permissible or target levels assessed in terms of human health protection occurred for 5 pollutants: PM10 suspended dust, arsenic and benzo(a)pyrene contained in PM10 suspended dust, nitrogen dioxide and ozone.
A significant improvement in air quality occurred in relation to dust pollution. The assessed year was another year with a significant decrease in the range of exceedances of PM10 air pollution.
In 2023, the average daily permissible level was exceeded only in two zones (Lower Silesia and Lesser Poland). In 2022, such exceedances occurred in 14 zones, and in 2021 in 25 zones.
The average annual concentration of PM10 suspended dust calculated from stations across the country in 2023 decreased by approximately 13%. compared to the previous year - indicated in the announcement.
A similar improvement occurred in relation to PM2.5 suspended dust - in 2023, for the first time in any of the zones, the average annual permissible level was not exceeded. In 2022, such an exceedance was recorded in 11 zones, and in 2021 - 29 zones.
