Air pollution represents at present the biggest threat to human health due to high levels of pollutant emissions, usually in high-traffic urban areas. Air pollution has been associated with a number of health problems, including heart disease and lung cancer. Urbanization associated with rapid industrial development has led to serious air pollution problems in many large cities across Europe with significant impact on public health and even on the global climate. Information on air quality in urban areas is an imp...

The long-term effect of economic development in post-communist Romanian urban areas brought exponential growth in motorization and uncontrolled urban expansion. As Romanian authorities still adopt conventional transport management policies, urban traffic congestion in the city of Cluj-Napoca has become a main contributor to noise pollution and air quality degradation, and has negative effects on the economy and social activities. Given the analysis of the structural and functional characteristics of the city of Cl...

The air pollution in Polish cities causes the formation of the phenomenon of smog. The reason for this phenomenon is mainly low society awareness of environmental protection and the methods of preventing the use of low-quality fuels in the home fireplaces. At the same time the development of the automotive industry contributes to this negative phenomenon. The air pollution in large and small Polish cities was analysed. The examples of cities fighting against the smog were also given. The research of the air qualit...

Environmental pollution has become one of the most debated issues of the contemporary times, being a consequence of using imperfect methods in production technologies. One of Romania?s areas where the environment has suffered as a result of human activities is the Jiu Valley, a place where the main activity was and continues to be mining. In this paper the authors aim to identify and quantify the pollution sources related to the coal mining activity from the western part of the Jiu Valley and, based on data relati...

The present paper uses microsimulation softs to identify the main problems regarding the speed humps location and proposes some improved solutions, with effects on traffic, pollution and safety. This paper also defines the notion of "speed hump", its main advantages, disadvantages and some implementation requests. The most accessible measures to increase road safety, both in economic and design terms, are the traffic calming measures, such as speed humps in different shapes and sizes, low-price solutions with sati...

Mining and processing activities are accompanied by air pollution. The paper assesses air and soil quality on the territory of copper-sulphide ores mining and processing plant in 2010?2013. The mining enterprise consists of a quarry, reclamation plant with a tailing pond, experimental-production facility for heap leaching and an underground mine under construction. The deposit has six ore shoots. Three of them are now excavated by surface mining, the underground mining techniques will be used for the others. Proce...

The Leningrad Region is a big/one the main subject of the Russian Federation with a highly developed industrial, transport and scientific potential. The article provides an analysis of some environmental problems typical for this region. Based on the aggregation of statistical information, data is provided on the structure and dynamics of total emissions, air pollutants, as well as emissions and sinks of greenhouse gases in various sectors of the economy of the Leningrad region. The features of deposition of subst...

The air is a mixture of different gases and particular matter, which make up for the earth?s atmosphere. They allow for the existence of all life on the earth. With the increase in population and the progress of development, more and more substance of natural origin and on general not occurring in the nature, which may affect harmfully on the environment, gets into the air. Dusts and gases, flowing in excess into the atmosphere, cause local and even global pollution. Since the beginning of 2017 all the time in Pol...

Modelling of fine particulate matter (PM2.5) requires new approaches for the evaluation of population?s exposure and associated health effects in various urban microenvironments. Such decision support tools are assisting local authorities in adapting proper plans for minimizing the resulting ecological and epidemiological impacts. An environmental decision support system (EDSS) with web-based GIS capabilities was developed to allow for examination of PM2.5 fraction concentrations in Ploiesti city, Romania. The air...

In most industrialized countries the problem of air pollution has become a major concern with significant social and political implications, is considered a barrier to economic and social development, drawing attention to these natural resources, materials and energy are not inexhaustible. In the literature are numerous researches on environmental pollution, correlated or not with the consequences on animals and food of animal origin, and not least on health human. In recent times the environmental pollution has d...
