Slight Advantage

Nature friendly technologies in today’s world are the subject of scientific research and the interest of local authorities and the residents themselves. In the context of the city, one of the most important issues is the neutralization of air pollution generated by transport and heating of the premises with the use of solid fuels. The article analyses differences of the response of traditional and photocatalytic paving stones. We analysed water absorption, frost resistance, tensile strength at splitting and abrasion of paving stones. It has been proved that paving stones exposed to atmospheric factors and pollution during one heating season met the assumed quality criteria. In addition, the results obtained for the characteristics analysed were higher than the results of samples tested in laboratory conditions. The results also indicate a slight advantage of photocatalytic cubes in terms of their resistance to abrasion and tensile strength at splitting. Traditional and photocatalytic paving stones withstand well the operating conditions. It seems that products based on TioCem® cement are the future implementation of pedestrian and traffic routes.

The Impact

Combustion processes, including the use of solid fuels for residential heating, are a widespread custom for many households. Residential heating is a significant source of ambient air pollution, yet it varies greatly by geography, meteorologic conditions, the prevalence of the type of solid fuel and the technologies used. This study evaluates whether residential heating affects the air quality through modelling three given scenarios of solid fuel boiler exchange at selected locations and comparing the results with measured data. The findings of this study suggest that according to the modelled data, the main air pollution contributor is residential heating since Dolni Lhota (daily average of PM10 = 44.13 μg·m−3) and Kravare (daily average of PM10 = 43.98 μg·m−3) are locations with no industry in contrast to heavily industrial Vratimov (daily average of PM10 = 34.38 μg·m−3), which were modelled for the heating season situation. Nevertheless, actual measurements of PM10 during the same period suggest that the average levels of air pollution were significantly higher than the modelled values for Dolni Lhota by 64% and for Kravare by 51%. Thus, it was assumed that PM long-range or/and transboundary transports were involved.

The article presents the problem of air pollution in polish cities on the example of Cracow. The focus was on one of the corrective actions taken by the city – free-fare public transport during high air pollution. Changes in the city's approach to this service since 2015 and consequences for the city budget were presented. Then, the efficiency of free-fare public transport in attracting new passengers was considered. The example of the Nysa town was cited, which introduced such permission for car drivers, but withdrew it three years later. In the next step, the concentration of air pollution before and after the activation of free-fare public transport in the heating season 2018/2019 was analyzed. Particulate matter PM10, nitrogen oxide and carbon monoxide were taken into account. There was no constant relationship between the changes in the level of these pollutants in the air and the full-paid (or fare-free) public transport. There is also no reason for the need to change parameters based on witch the fare-free public transport is activated. Finally, the necessity of further efforts of central and local authorities to improve air quality as well as further research on sources of air pollution and efficiency of undertaken actions was emphasized. Keywords: fare-free public transport, air pollution, environmental protection

<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>

Abstract The article studies the existence experience of historical cities as centers of tourism development as in the case of Elabuga. The city of Elabuga is among the historical cities of Russia. The major role in the development of the city as a tourist center is played by the Elabuga State Historical-Architectural and Art Museum-Reserve. The object of the research in the article is Elabuga as a medium-size historical city. The subject of the research is the activity of the museum-reserve which contributes to the preservation and development of the historical look of Elabuga and increases its attractiveness to tourists. The tourism attractiveness of Elabuga is obtained primarily through the presence of the perfectly preserved historical center of the city with the blocks of integral buildings of the 19th century. The Elabuga State Historical-Architectural and Art Museum-Reserve, which emerged in 1989, is currently an object of historical and cultural heritage of federal importance. Museum-reserves with their significant territories and rich historical, cultural and natural heritage have unique resources for the implementation of large partnership projects. Such projects are not only aimed at attracting a wide range of tourists, but also stimulate interest in the reserve from the business elite, municipal and regional authorities. The most famous example is the Spasskaya Fair which revived in 2008 in Elabuga. It was held in the city since the second half of the 19th century, and was widely known throughout Russia. The process of the revival and successful development of the fair can be viewed as the creation of a special tourist event contributing to the formation of new and currently important tourism products.

The image of the city is a spatio-temporal continuum in which everything is interconnected, it exists as a single monolith expressing itself in the general atmosphere. The visual image of the city may contain two planes of meanings: culturally ratified and universally valid, expressed by cultural codes, and also significant only to those who are viewing the image. Therefore, the content of the visual image depends on who the subject of perception is, what he pays attention to and in what situation the process of perception of the image occurs.

The subject of the article is an analysis of the three aspects of depicting urban space of Eastern Ukraine, focusing specifi cally on the Donbass region and the city of Kharkov as depicted in the novels Voroshilovgrad (2010) and Mesopotamia (2014) by Serhiy Zhadan. The urban space of Eastern Ukraine overlaps with the most important values that shape a person’s personality and aff ect her or his self-identifi cation. The city space is also a “place of memory” and experiences of generations that infl uence current events. In addition to the historical and axiological dimension, the imaginative aspect of space is also important. This approach is used by the author to describe the urban space as a functioning imagination or stereotypes associated with it as opposed to its realistic depiction.

Firm Entry And Exit

The impact of environmental regulation has been an important topic. Based on the Chinese Custom Database and China City Statistical Yearbook, this paper investigates the effect of environmental regulation on export values and explores potential mechanisms and heterogeneous effects. Taking advantage of China’s first comprehensive air pollution prevention and control plan, the Air Pollution Control in Key Zones policy, as a quasi-natural experiment, we employ the difference-in-differences method to examine the causal relationship between environmental regulation and exports. We find the statistically significant and negative effect of environmental regulation on exports at the city level. Moreover, we find that the potential mechanism is the change in export values caused by firm entry and exit, especially by exiters, rather than the change in the number of exporting firms in the city caused by firm entry and exit. In addition, we find the heterogeneous effects of environmental regulation based on the differences of environmental policy across cities and the Broad Economic Categories classification.
