Abstract
Section snippets
Measurement sites
The research area was the northwest part of the Czech Republic. The North Bohemian lignite basin is part of the so-called ‘Black Triangle’, located at the tri-border of the Czech Republic, Poland, and Germany. The exploitation of coal and its use for industrial heat and power generation, as well as household heating, has led to worsened air quality here, especially in terms of concentrations of particulate matter and polycyclic aromatic hydrocarbons (PAH) (Hůnová, 2020).Four monitoring sites (
Results and discussion
The annual average PM10 concentrations ranged from 17.9 to 24.2 μg·m-3 at the basin sites and were 10.5 μg·m-3 at the mountainous Rudolice site (Table 2). In contrast to the initial expectation, the highest seasonal average concentrations were not observed in winter, when emissions from residential heating play an important role in air quality. The reason was the long-lasting deteriorated dispersion conditions in spring and autumn described in detail in the Text S3. The significant impact of
Conclusions
Annual offline data from four stations and semi-annual time series of combined online and offline data yielded similar findings. Utilizing sites in areas with differing meteorological conditions allowed for a more detailed distinction between locally, regionally, and long-range transported particles, including secondary aerosols.Both approaches consistently identified surface coal mining emissions as the dominant contributor to PM10 mass in the Most Basin area, making them the main priority for

期刊介绍:
Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health.
Subject areas include, but are not limited to:
• Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies;
• Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change;
• Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects;
• Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects;
• Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest;
• New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
