Owing to the rapidly growing and inefficient usage of fuel, air pollution has increased in Istanbul. The levels are affected by the weak dispersion conditions in the city. The strength of the inversion can be explained by the temperature difference between the top and bottom boundaries and their height. In this study, nighttime surface inversion heights have been found to range between 84 m and ...

Different time series analysis of daily air pollution of Isfahan city were performed in this study. Descriptive analysis showed different long-term variation of daily air pollution. High persistence in daily air pollution time series were identified using autocorrelation function except for SO2 which seemed to be short memory. Standardized air pollution index (SAPI) time series were also ...

The causal relationship between happiness and air pollution is examined using a sample of 14 European countries. Two sets of results are presented using the notion of Granger causality. For individual countries, the existence of a unidirectional or bidirectional causal structure for almost half of the countries can be observed. The panel approach, on the other hand, provides some support for the ...

Introduction Concern about urban air quality is not new. Complaints were recorded in the 13th century when coal was first used in London. Since the middle of the 19th century, the atmosphere of the major British cities was regularly polluted by coal smoke in winter, giving rise to an infamous mixture of fog and smoke known as smog. Today the emphasis has shifted from the pollution ...

Epidemiological research has identified that there exists a correlation between days of high air pollution and the timing of death for large numbers of individuals. Before economic values can be attached to these impacts, however, greater information is required on the extent of life lost and the socio-economic characteristics of those at greatest risk. It may be more fruitful to base willingness ...

Air pollution is one of the most crucial current environmental problems, especially in urban areas. To confront air pollution, the European Union has implemented several policies and programmes. Among these, the Auto-oil Programme is a cost-effective framework which involves all relevant actors (car-makers, oil industries, governments, local authorities, etc.) in concerted action. Athens faces a ...

The Thematic Strategy on air pollution aims to improve European air pollution significantly by 2020. This report from the European Environment Agency looks a further ten years into the future, and brings together two major policy challenges — combating climate change and reducing air pollution in an integrated way. Thus, the report analyses projected changes in European air quality up to 2030, ...

Environmentalists, regulators, health scientists, and journalists are the main purveyors of information on air pollution health risks. Unfortunately, these groups create the appearance that harm from air pollution is much greater and more certain than suggested by the underlying evidence. The incentives in air pollution health research encourage risk exaggeration, because information purveyors ...

The present work aims at a detailed study and explanation of the pollution transport in the air basin over south-western Bulgaria and northern Greece and assessment of the air pollution exchange between Bulgaria and Greece. Some well-known specific climatic air pollution effects were studied and explained. Calculations were made of the SO2 pollution of the Balkan Peninsula from both Greek ...

Urban air pollution is on the rise in many cities of the world. There are associated health impacts that affect urban residents, especially the poor. By doing economic valuation, it is possible to draw the attention of citizens, policy-makers and, of course, researchers to the extent of damage and the value of it. In this paper, such a valuation is done using time-series data for the suburb of ...

Air pollution affects human health, particularly sensitive groups such as children, pregnant women, elderly people and patients with chronic respiratory diseases in many ways, including reduced lung function, increased morbidity and infant mortality. Many epidemiological studies have shown positive association between respiratory health and ambient air pollution. This study tries to assess the ...

Environmental quality and economic development are often thought to be causally linked. This paper empirically examines the impact of economic growth and international environmental treaties on air pollution emissions in several transition countries using panel data analysis. The results indicate that economic growth, proxied by the conventional input factors of production, total labour force and ...

The science of particulate air pollution and health has a long, rich, and complex history. More detailed versions of various aspects of this history can be found elsewhere.1-5 A simple stylized version of this history may suggest that, until the early to mid-1900s, the health effects of air pollution were largely a matter of instinctive observations, suspicion, and superstition. In fact, one of ...

Abstract: Epidemiological and toxicological studies have reported adverse health effects in response to exposure to air pollution including nitrogen dioxide (NO2). Some of these studies have indicated that specific populations may be at different risk of NO2 related health effects that others. Adverse health effects from air pollution are not equally distributed among populations and ...

This paper analyses the effect on the environment of electricity purchase from independent power producers (IPPs) in the case of Thailand. The environmental implication is evaluated in terms of the net change in emission of air pollutants with electricity purchase from IPPs by a utility. The main finding of the study is that electricity purchase from a non-dispatchable IPP plant based on ...

A new approach for Sensitivity Analysis (SA) in the field of air pollution modelling is proposed and applied to the Unified Danish Eulerian Model (UNI-DEM), a large-scale air pollution model. The SA requires numerous model experiments with different values of the studied parameters. By simultaneous variation of these parameters we produce a set of multidimensional discrete functions. These huge ...

Splitting techniques are commonly used when large-scale models, which appear in different fields of science and engineering, are treated numerically. Four types of splitting procedures are defined and discussed. The problem of the choice of a splitting procedure is investigated. Several numerical tests, by which the influence of the splitting errors on the accuracy of the results is studied, are ...
