Air quality investigations have not been undertaken in Blace until now. Identifying the presence of different types of epiphytic lichens was performed in the summer 2012 in Blace (southeastern Serbia), and selected rural settlements around Blace, in order to establish the air quality of the area. The analysis of samples from described localities indicated the presence of 25 lichen taxa from 19 genera. Using the Index of Atmospheric Purity (IAP), it was found that there are 2 different air pollution zones in Blace: ?lichen desert? and ?transitional? or ?struggle zone?, which includes the periphery of the city. In these zones the air is moderately polluted. In the urban area of Blace there is no ?normal? zone, but one was detected in the surrounding rural areas.

Transboundary air pollution (TAP) and local air pollution (LAP) influence the air quality of urban areas. Fukuoka, located on the west side of Japan and affected by TAP from the Asian continent, is a unique example for understanding the contribution of LAP and TAP. Gaseous species and particulate matter (PM) were measured for approximately three weeks in Fukuoka in the winter of 2018. We classified two distinctive periods, LAP and TAP, based on wind speed. The classification was supported by variations in the concentration of gaseous species and by backward trajectories. Most air pollutants, including NOx and PM, were high in the LAP period and low in the TAP period. However, ozone was the exception. Therefore, our findings suggest that reducing local emissions is necessary. Ozone was higher in the TAP period, and the variation in ozone concentration was relatively small, indicating that ozone was produced outside of the city and transported to Fukuoka. Thus, air pollutants must also be reduced at a regional scale, including in China.

AbstractA recent survey of epiphytic lichens in the Jardin du Luxembourg has shown there to be a marked improvement in the air quality of Paris over the past decade. Recolonization by at least 11 lichen species has occurred during that period. It has taken almost 100 years for epiphytic lichens to re-establish in the Jardin du Luxembourg, where William Nylander in the 1890s was able to amply confirm his far reaching hypothesis, made 30 years earlier, on the direct relationship between lichen survival and air pollution.

AbstractThe composition and richness of the microfauna on lime trees was surveyed in relation to the distribution and cover of lichens in Belfast. Parameters used to help interpret the results included distance from the city centre and available data on air quality. The percentage epiphyte cover on the trunks of lime trees was significantly correlated with distance from the city centre whereas that on tree bases as not. In contrast, the number of microfaunal species revealed strong positive correlations with distance for both the bases and the trunks of trees. Most of this increase in microfaunal species richness towards rural areas was due to protistans which are thus proposed as useful bioindicators of air pollution. The total species richness of fauna showed slight negative correlation with smoke but not SO2 levels.

Recent studies and reports on cleanliness and quality of air indicate that Poland belongs to a group of European Union countries where air pollution is at one of the highest levels. Low air quality in many areas of Poland should be considered not only in the context of environmental destruction, but also in the context of the developmental negligence of the country in the context of the care of ecology. This article summarizes the results of research into the scale of threats regarding air quality occurring locally in the city of Słupsk. The paper also discusses the scale of air pollution-related risks and their consequences for the life and health of the individual.

Possible Cause

On March 24, 2020, a partial lockdown was decreed in the state of São Paulo, Brazil, as a measure to hinder the spread of COVID-19, which consisted in prohibiting crowding and advising people to stay home, except for urgent or extremely necessary matters. Based on studies performed in other countries, this study aims to assess the impacts of the lockdown on the air quality of five cities in the state of São Paulo. Our study was conducted by using particulate matter and nitrogen dioxide as air quality indicators, and by correlating the contaminants concentrations with weather data. The results showed an increase in these contaminants in all cities within the first weeks after the lockdown compared with the weeks before the decree and with the same period in previous years. This result is inconsistent with the literature. Therefore, a secondary goal was set to investigate the possible cause (or causes) of such deterioration in air quality, which led to the increased number of wildfires. The anomalous dry weather favored the burning of vegetation in agricultural rural areas and in small, vegetated areas near the municipalities, and limited pollution scavenging by rainfall, both of which contributed to higher pollution concentration. We hypothesize the possible effects of worse air quality on the aggravation of COVID-19, but further research is necessary to obtain a complete assessment.

Bioindication of air pollution in the city of Nis, by using epiphytic lichens, was performed for the first time in 1992. In this paper the authors present the results of repeated investigations in 2002, by using new, modern method, and their comparison with the former investigations. In repeated investigations, on 59 investigated spots, the authors established the presence of 42 lichen taxa, 3 zones with different air pollution level ("lichens desert", "transitional zone" and "normal zone") and two subzones ("narrow transitional zone" and "wider transitional zone"), as well. As the most sensitive, some Melanelia-species (M. elegantula, M. exasperata, M. glabra), Evernia prunastr and Flavoparmelia caperata, were established while on the other hand, Phaeophyscia orbicularis, Physcia adscendens, Ph. stellaris and Lecanora argentata were the most tolerant.

<p>Recent years have brought a significant increase in public awareness of the issue of poor air quality in Poland. It is understandable that this problem has a direct impact on the quality of life of citizens of this country. Over the last few decades a concern over the health effects associated with air pollution was growing, mainly due to their carcinogenic and mutagenic properties. Various actions initiated by non-governmental organizations forced the authorities to undertake certain measures aimed at improving the quality of air in Poland, which, in the reports of the European Environment Agency is listed as one of the most polluted countries in the entire European Union. A model example here is the Krakow agglomeration. The city, located in a basin extending in the Vistula valley, surrounded on three sides by hills, in the cold period of the year struggles with the problem of poor air quality (very high concentrations of particulate matter and benzo(a)pyrene).</p><p>The objective of this research was better characterization of two major elements responsible for poor air quality in Krakow agglomeration: existing sources of pollution and  local meteorology during heating season (HS) and  non-heating season (NHS). Samples were collected with 24h resolution using Low-Vol samplers in Krakow (50°00'38.1"N 19°56'57.1"E, Kurdwanow, Malopolska, South Poland) from February 2014 to January 2015. Based on the results of polycyclic aromatic hydrocarbons, cations, anions, mercury, organic and elemental carbon analyzes of samples of particulate matter collected in the city’s atmosphere, sources have been identified and classified them from the most to the least significant ones. The modeling tool Hybrid Single-Particle Lagrangian Integrated Trajectory model (HYSPLIT), developed by NOAA’s Air Resources Laboratory, was used to investigate the possible trajectories of air pollutants.</p><p>This research was partially financed by the AGH UST grant 16.16.210.476 subsidy of the Ministry of Science and Higher Education. PF and AS have been partly supported by the EU Project POWR.03.02.00-00-I004/16. The infrastructure of the AGH Center of Energy in Kraków was applied in order to determine the concentration of ions.</p>

Epiphytic lichens were used dor bioindication of air pollution in the city of Vranje for the first time. In 43 investigated places, the authors established the presence of 38 lichen taxa from 20 genera. By calculating the index of atmospheric purity (IAP), they established three zones with different air pollution levels (a "lichen desert zone", a "transitional zone", and a "normal zone") and two subzones (a "narrow transitional zone", and a "wider transitional zone"). The species Melanelia exasperatula, M. glabra, Lecanora allophana, Lecidella elaechroma, Ochrolechia sp, Ramalina sp., and Parmelina quercina were established as the most sensitive. On the other hand, Phaeophyscia orbicularis, Xanthoria parietina, and Parmelia sulcata were the most tolerant.
