Urban Air Quality Monitoring in Decarbonization Context; Case Study—Traditional Coal Mining Area, Petroșani, Romania

Livezeni is one of the few active remaining collieries from Jiu Valley, in the Meridional Carpathian Mountains. Mining waste facilities classification is introduced according to Romanian technical prescription PT-C 39. Preliminary geotechnical studies on the basement rocks and the waste material are necessary to define the maximum height and the slope angle for ensuring the stability of the waste dump. The first step supposes modeling the morphology of the area based on various information sources. The decision on the shape and geometry of the dump could be taken according to various geotechnical, technological, legal and economic aspects involved, based on analysis done on the digital terrain model. A computerized design process allows the possibility to analyze several variants in less time and ensure results that are more accurate and useful in the later stage of building and remediation of the area. This process is illustrated on the waste dump Livezeni.

“…Several case studies [2,3,7] analysed the air quality in Petrosani, each one analysing in particular the impact generated by road traffic on air quality and implicitly on the health of population. The new environmental objectives included in the Economic, Social and Environmental Development Strategy of the Jiu Valley (2022-2030) refer to environmental monitoring in all 6 jurisdictions, which will contribute to a much broader analysis of air quality and population health.…”

Air quality monitoring in the eastern Jiul Valley

Jiu Valley is an area with a tradition in the field of mining. Over time, coal mining has been the main driver of the local economy. The decrease in the level of coal use also led to the closure of mining units in the Jiu Valley. Such transitional actions require calibration to climate, environmental and health responsibilities. Air pollution specific to the area has, perhaps, the most significant impact on the quality of population’s life in terms of affecting health. The paper presents the air quality monitoring in the Eastern Jiu Valley for a period of four months (one sampling campaign/month), between February and May 2023, in six monitoring points, with the help of the Mobile Environmental Laboratory which has the facility of simultaneously determining several samples for quick identification of polluted areas. The established monitoring program includes the monitoring points, monitoring frequency and duration, as well as the areas where the mobile laboratory was located. The analysed data highlight the air quality in the Eastern Jiu Valley to establish the medium and long-term objectives in each area where the mobile laboratory was located, as well as the level of exposure of resident population. The concentration levels found in different urban areas illustrate the average concentrations of dust, gases and ozone caused by both activities in the area and road traffic.

“…These houses were designed in a specific architectural style, with a single level and adjacent garden plots. It is a neighborhood where many families with modest material possibilities currently live [3,13]. Unfortunately, despite the beauty and cultural value of the Historical Center of Petroșani, this area has become one of the most polluted in the city due to the low standard of living and the lack of alternative heating sources.…”

“…All this, combined with an alarming increase in the number of oncological patients in the area, forces a different approach to highlight through comparative studies the influence of different sources of air pollution and, as far as possible, their quantification. At different levels of depth, the documentation of the subject was started about four years ago by collectives that did not lack students, masters or doctoral students and the collective of authors, with different responsibilities and contributions [2, 3,4,5]. Thus, two important sources were identified that negatively influence the air quality in the analyzed area, namely the noxious gases and Particulate Matters resulting from the increase of the number of vehicles and implicitly the values of road traffic [6], but also as a result of the systematic burning of some fuels and/or/especially cloth and footwear waste in the historic districts of the cities.…”

The restructuring of the mining sector in the Jiu Valley basin in the context of decarbonization has as its main goal the reduction of atmospheric pollution. Despite the fact that previous studies suggest an overall improvement in air quality as a result of this process, most ignore the lack of an immediate alternative to the use of coal as a primary energy resource both locally and regionally. This lack of alternatives has been found to have a negative influence on air quality through the noxious gases and Particulate Matter released into the atmosphere following the burning of some fuels, cloth and footwear waste, especially in the historical residential areas of the cities. In this paper, some of the results obtained from the instrumental determinations carried out in different areas of the Petroșani Municipality are presented, with special regard to the air quality in the Historical Center of this city.
