“…The contribution to BaP concentrations varies in different parts of the Czech Republic and depends on the position and density of its sources. The greatest burden by emissions of BaP occurs in the Moravian-Silesian region due to the higher proportion of black coal combustion in bulk-burning-type boilers in households [11][12][13][14].…”

“…A closer look at the modeling results shows that the absolute contribution of foreign sources calculated by the CAMx model (www.camx.com, accessed on 15 December 2023) is comparable at these sites. The spatial distribution of annual averages of BaP presented that the annual mean concentration measured at the stations decreases with increasing distance from the Czech-Polish border [13,14,21,22]. The Ostrava-Radvanice site is an exception.…”

This contribution deals with the assessment of air pollution caused by atmospheric aerosol particulate matter fraction PM10 and benzo[a]pyrene (BaP) in the urban agglomeration of Ostrava, located in the Czech Republic in Central Europe. The motivation for this research was the need to identify the sources of air pollution in the area, particularly in locations where the contribution of different sources to concentrations of pollutants of concern has not been elucidated yet. In this study, source apportionment in the vicinity of the industrial hot spot was performed by statistically evaluating measured pollutant concentrations as a function of meteorological variables and using the Positive Matrix Factorization (PMF) receptor model. A significant methodological innovation and improvement over previous assessments was the higher monitoring resolution of benzo[a]pyrene, with samples collected at three-hour intervals instead of the standard 24 h collection period. The key findings indicate that in the cold part of the year, secondary particles—specifically sulfates and ammonium nitrates—were responsible for the most significant portion of PM10 air pollution throughout the area of interest. The contribution of these particles ranged from one-third to two-fifths of the total concentration, except at the industrial site of Ostrava–Radvanice (TORE), where they accounted for approximately one-fifth of the measured pollution concentration level. Emissions from individual household heating were identified as the main source of this type of pollution. With regards to benzo[a]pyrene air pollution, this study found that in the whole area of interest, except for the Ostrava–Radvanice site, it mainly originated from individual heating with coal (90%). In contrast, at the Ostrava–Radvanice site, two-thirds of the benzo[a]pyrene pollution came from the premises of Liberty Ostrava a.s., primarily from coke production, and less than one-third came from local domestic heating. This study also determined the spatial extent of the occurrence of extremely high benzo[a]pyrene concentrations (above 5 ng/m3), which are estimated to affect nearly 10,000 inhabitants. The results confirm that the data from the TORE station are only representative of its immediate surroundings and are not applicable to the assessment of air quality and causes of air pollution in the whole city of Ostrava or the urban area of Ostrava–Radvanice as a whole. After years of research, these findings provide the Ministry of the Environment of the Czech Republic and the government with an accurate basis for implementing measures to address the identified pollution sources in the area of interest. The success of this study was made possible by the adoption of a more detailed sampling approach, which involved a resolution of 3 h instead of 24 h. This methodological improvement is a significant finding and will be useful for future source apportionment studies.

A significant methodological innovation and improvement over previous assessments was the higher monitoring resolution of benzo[a]pyrene, with samples collected at three-hour intervals instead of the standard 24-hour collection period. The key findings indicate that in the cold part of the year, secondary particles - specifically sulphates and ammonium nitrates - were responsible for the most significant portion of PM10 air pollution throughout the area of interest. The contribution of these particles ranged from one third to two fifths of the total concentration, except at the industrial site of Ostrava-Radvanice (TORE), where they accounted for approximately one fifth of the measured pollution concentration level. Emissions from individual household heating were identified as the main source of this type of pollution.

“…This area is also characterized by a high number of settlements with individual heating using solid fuels and a dense transport infrastructure. Additionally, unfavorable meteorological conditions contribute to the transboundary transport of pollutants across Czech-Polish state borders [13,14]. Due to these conditions, air quality has not complied with the national and WHO standards (WHO global air quality guidelines) over the long term [15].…”

Particulate Matter (PM) air pollution is a serious concern in the northern Moravia region of the Czech Republic. This study aimed to evaluate the association between the risk of acute hospital admissions for cardiovascular (CVD) and respiratory diseases and PM2.5 concentrations using a geographic information system (GIS). The data on acute hospital admissions for cardiovascular (I00-99 according to ICD-10) and respiratory (J00-99) diseases was assigned to 77 geographical units (population of 601,299) based on the residence. The annual concentrations of PM2.5 in the period from 2013–2019 were assigned to these units according to the respective concentration iso-shapes. The Incidence Rate Ratio (IRR) and 95% confidence interval (CI) were calculated for each concentration category and then compared with the reference category. Statistical analyses were performed using SW STATA v.15. In 2013, approx. half of the population (56%) belonged to the PM2.5 category 34–35 µg·m−3, and 4% lived in PM2.5 concentrations ≥ 38 µg·m−3. During the analysed period, the average concentrations decreased from 30.8 to 21.4 µg·m−3. A statistically significant risk of acute hospitalization for CVD causes was identified in categories ≥ 36 µg·m−3, and for respiratory causes from 34–35 µg·m−3. With increasing concentrations, the risk of both acute cardiovascular and respiratory hospitalizations increased.
