“…There are resembling research in this issue such as the effect of sulfur dioxide and other pollutants on the anatomic and morphologic changes of needles and stem anatomy of Scots pine (Smith and Davis 1978, Suchara et al 2014, Mortensen et al 1989, other conifers (Burkhardt and Pariyar 2014, Nuhoğlu 1993, Tjoelker and Luxmoore 1991, Meng et al 1995, Soda et al 2000, Okano et al 1985, and the other plants Nuhoğlu 2005, Anonymous 2000, Anonymous 2002, Günthardt-Goerg et al 1993, but there are no research the anatomic and morphologic changes of the cross section of Turkish pine's needles caused by air pollutants in Turkey and the other countries. For this reason, it is estimated that the findings about the anomalies of cross-section of Turkish pine's needles owing to air pollutants emitted from thermal power plants are investigated firstly.…”

In this study, the anatomical and morphological anomalies in the cross-section of Turkish pine needles (Pinus brutia Ten.) caused by air pollutants that was emitted from the Kemerköy (Gökova) Thermal Power Plant (KTPP) were investigated with fieldworks and microscopic techniques. At the end of the land researches, it was found out that air pollutants such as sulfur dioxide, nitrogen oxides and fly ash had caused serious injury, and caused 3 year-old-needles fell very early. On the microscopic observation on the cross-sections of the needles, it was determined that the diameter of the main and especially subordinate resin canal dilated too and the number of resin canals increased. It was also observed that the endodermis layer in transmission corymbs and the cells in transfusion texture had become thin, and the intra-cellular material had disappeared owing to air pollutants.

“…At present, there are no large hot spots of acid bark and the whole CZ has been re-colonised by lichens. The recovery of bark throughout CZ has been described in more detail in Suchara (2012) and Suchara et al (2014).…”

The Czech Republic (CZ) had extremely high emissions and atmospheric deposition of pollutants in the second half of the 1980s. Since the beginning of the 1990s, moss, spruce bark and forest floor humus have been used as bioindicators of air quality. In the first half of the 1990s, seven larger areas were found to be affected by high atmospheric deposition loads. Six of these "hot spots" were caused by industrial pollution sources, mainly situated in coal basins in the NW and NE part of the country, and one large area in the SE was affected by increased deposition loads of eroded soil particles. After restructuring of industry in CZ, these hot spots were substantially reduced or even disappeared between 1995 and 2000. Since 2000, only two larger areas with slightly increased levels of industrial pollutant deposition and a larger area affected by soil dust have repeatedly been identified by biomonitoring. The distribution of lead isotope ratios in moss showed the main deposition zones around important emission sources. Very high SO emissions led to extreme acidity of spruce bark extracts (pH of about 2.3) at the end of the 1980s. The rate of increasing bark pH was strikingly similar to the rate of recovery of acid wet deposition measured at forest stations in CZ. By about 2005, when the median pH value in bark increased to about 3.2, the re-colonisation of trees by several epiphyte lichen species was observed throughout CZ. An increase in the accumulation of Chernobyl-derived Cs in bark was detected at about ten sites affected by precipitation during the time when radioactive plumes crossed CZ (1986). Accumulated deposition loads in forest floor humus corresponded to the position of the moss and bark hot spots.

“…The chemistry of rime (as a part of horizontal deposition) has been studied recently at 10 regional mountain-top sites in the CR [204][205][206][207], nevertheless the contribution of rime to atmospheric deposition has been unclear thus far. Improving ambient air quality and decreasing atmospheric deposition have also been demonstrated by long-term nationwide biomonitoring, including analyses of mosses and tree bark [208][209][210][211][212][213]. Furthermore, peat bogs proved useful for reflecting the history of heavy metal atmospheric deposition.…”

Based on an analysis of related core papers and reports, this review presents a historical perspective on ambient air pollution and ambient air quality development in the modern-day Czech Republic (CR) over the past seven decades, i.e., from the 1950s to the present. It offers insights into major air pollution problems, reveals the main hot spots and problematic regions and indicates the principal air pollutants in the CR. Air pollution is not presented as a stand-alone problem, but in the wider context of air pollution impacts both on human health and the environment in the CR. The review is arranged into three main parts: (1) the time period until the Velvet Revolution of 1989, (2) the transition period of the 1990s and (3) the modern period after 2000. Obviously, a major improvement in ambient air quality has been achieved since the 1970s and 1980s, when air pollution in the former Czechoslovakia culminated. Nevertheless, new challenges including fine aerosol, benzo[a]pyrene and ground-level ozone, of which the limit values are still vastly exceeded, have emerged. Furthermore, in spite of a significant reduction in overall emissions, the atmospheric deposition of nitrogen, in particular, remains high in some regions.
