Received: 30 June 2020; Accepted: 3 September 2020; Published: 4 September 2020 Abstract: Thirty years ago, Northern Bohemia in the Czech Republic was one of the most air polluted areas in Europe. After political changes, the Czech government put forward a research program to determine if air pollution is really affecting human health. This program, later called the “Teplice Program”, was initiated in collaboration with scientists from the United States Environmental Protection Agency (US EPA). This cooperation made possible the use of methods on the contemporary level. The very high concentrations of sulphur dioxide (SO2), particulate matter of 10 micrometers or less (PM10), and polycyclic aromatic hydrocarbons (PAHs) present in the air showed, for the first time, the impact of air pollutants on the health of the population in mining districts: adverse pregnancy outcomes, the impact of air pollution on sperm morphology, learning disabilities in children, and respiratory morbidity in preschool children. A surprising result came from the distribution of the sources of pollution: 70% of PM10 pollution came from local heating and not from power plants as expected. Thanks to this result, the Czech government supported changes in local heating from brown coal to natural gas. This change substantially decreased SO2 and PM10 pollution and affected mortality, especially cardiovascular mortality.

Introduction Mining districts in Northern Bohemia, the northern region in the Czech Republic, were in the late 1980s one of the most air polluted regions in Europe. Northern Bohemia is a highly industrialized coal basin. Brown coal containing 1–5% sulphur was used for power plants, industry, and local heating. Geographically, this area is a valley sandwiched between the Ore Mountains approximately 1000 m above sea level to the north and the Middle Bohemia Highlands, approximately 800 m above sea level to the south. The geographic location and prevailing winds from the northwest and southwest give rise to frequent inversions. The average concentration of sulphur dioxide (SO2) in the years 1982–1990 was 103 µg/m3, and that of total suspended particles (TSP) was 102 µg/m3 [1]. Air pollution from these sources caused extensive deforestation of conifers in the Ore Mountains. Air pollution significantly affected human health. Kotesovec et al. [2] observed that increased daily mortality was related to air pollution for total mortality, cancer, and cardiovascular mortality, and significant shortening of life expectancy by 2 years for males and females. Sram [3] studied the impact of air pollution on pregnancy outcomes, diagnosed as congenital anomalies (CGA) or lower birth weight (LBW) in medical records of maternity hospitals between the years 1982 and 1986. In the district of Usti nad Labem, 7644 pregnancies were diagnosed with 9.8% CGA. In the district of Teplice, 7190 pregnancies were diagnosed with 8.2% CGA. This was approximately 4–5 times higher in this Int. J. Environ. Res. Public Health 2020, 17, 6454; doi:10.3390/ijerph17186454 www.mdpi.com/journal/ijerph Int. J. Environ. Res.

Morbidity of children in the mining districts of Northern Bohemia differed significantly for children 0–6 years old: from the morbidity nationwide as follows [4]: respiratory diseases: 2.90 vs. 0.54 nationwide (No. of cases/100), for children 0–6 years old: mental illness: 1.06 vs. 0.53 nationwide (No. of cases/100); respiratory diseases: 2.90 vs. 0.54 nationwide (No. of cases/100), for children 7–15 years old: mental illness: 1.06 vs. 0.53 nationwide (No. of cases/100); respiratory diseases: 1.40 vs. 0.45 nationwide (No. of cases/100), for children 7–15 years old: mental illness: 4.09 vs.2.00 nationwide (No. of cases/100). respiratory diseases: 1.40 vs. 0.45 nationwide (No. of cases/100), The health consequences of environmental pollution became one of the major concerns of the mental illness: 4.09 vs.2.00 nationwide (No. of cases/100).
