Air pollution


The assessment was prepared on the basis of measurement results for 2016 in accordance with the “Guidelines for annual assessment of air quality in zones for 2016 in accordance with Article 89 of the Environmental Protection Law Act on the basis of applicable national and EU law”. (Chief Inspectorate of Environmental Protection, Warsaw, 2017)

The annual evaluation used the results of modelling of PM10 particulate matter, PM2.5 particulate matter, benzo(a)pyrene, nitrogen dioxide and sulphur dioxide, carried out for the whole Poland, commissioned by the Chief Inspectorate of Environmental Protection as part of the work entitled: “The impact on the environment of the environment”. “Results of modelling of concentrations of PM10, PM2,5, SO2, NO2, B(a)P for the annual air quality assessment for 2016.

PM10 suspended particulate matter:

The results of modelling indicate that only 24-hour values are exceeded.

Sulphur dioxide :

The distribution of sulphur dioxide concentrations in the zones of the Kujawsko-Pomorskie Voivodeship does not indicate the occurrence of areas exceeding the normative values of both 1-hour concentrations and 24-hour concentrations (expressed as percentile 99.7 for an annual series of 1-hour concentrations, and percentile 99.2 for an annual series of 24-hour concentrations).

Nitrogen dioxide

The distribution of nitrogen dioxide concentrations in the zones of Kujawsko-Pomorskie voivodship does not indicate the existence of areas exceeding the normative values.

Benzo(a)piren

The average annual concentrations of benzo(a)pyrene in PM10 dust indicate a significant area of exceedances in each zone within the voivodship.

According to the classification carried out for reasons of human health protection, all four zones in the voivodship (the Bydgoszcz agglomeration, the city of Toruń, the city of Włocławek and the Kujawsko-Pomorskie zone) were classified in Class C. This makes it necessary to draw up air protection programmes if they have not already been drawn up.

The decision to classify the zones as unfavourable class C in 2016 was made:

In the Bydgoszcz agglomeration:

  • oversized 24-hour concentrations of PM10 particulate matter (ul. Warszawska, Plac Poznański),
  • average annual concentration of benzo(a)pyrene in PM10 dust (Plac Poznański)

Dust is a substance different from other air pollutants due to its origin. On the one hand, it is emitted as a primary pollutant during various processes (anthropogenic and natural); on the other hand, it is generated as a secondary pollutant as a result of the transformation of its precursors: sulphur dioxide, nitrogen dioxide, ammonia and volatile organic compounds. It also appears as a result of re-suspension processes from the earth’s surface.
