A climatological analysis of atmospheric concentrations of primary air pollutants in Athens, Greece, is presented for the 11-year period 1987-1997, since the automated local air pollution network operating by the Ministry of Environment started to record all conventional pollutants. The...

This paper deals with the analysis of atmospheric concentrations of secondary photochemical air pollutants in Athens for the 11-year period 1987-1997. Photochemical pollution, which seems to be the most serious air pollution problem in Athens, is originating mainly from the transformation of car...

Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO2, NO, and NO2 from “sweet” natural gas while “sour” gas emits SO2 in addition; incomplete combustion...

During recent years special attention has been paid to various environmental impacts from aircraft emissions. The effects become more important considering the present situation in the air traffic sector and future expectations for higher air travel demands. In this paper the evolution of aircraft...

The problem of air pollution is one of the most important problems faced by the world in the context of large urban agglomerations. Numerous activities are being undertaken all over the world to both counteract existing pollution and prevent the emergence of another one. Manufacturing is one of the...

Over the last few decades, the evidence on the adverse effects on the health of air pollution has been raised. Mortality is the most important health effect of ambient air pollution. We studied the relation between mortality and criteria pollutant air in Tehran, one of the highly industrialized...

In the present study an assessment of the influence of the ambient air pollution on the incidence of the Childhood Asthma Admissions (CAA) is attempted by using cross spectrum analysis. The medical data concern the hospital registries of the three main Children’s Hospitals of Athens for the 14-year...

An attempt is made for a first general study of the relation between high/very high concentrations of nitrogen dioxide and ozone with the discomfort index (DI) values. The nitrogen dioxide data of «Patision» station and ozone data of «Liosia» and «Marousi» station have been analysed. The relation...

Earth is consisting of land, air and water. Air contains oxygen, nitrogen, carbon dioxide, water vapor, other gases are present above the permissible limit, and it creates effects on human health. It is one of the most important public health issues due to development of urbanization...

Air pollution monitoring is becoming increasingly important, with an emphasis on the effects on human health. Because nitrogen dioxide (NO2) and sulphur dioxide (SO2) are the principal pollutants, many models for forecasting their potential harm have been created. Nonetheless, making precise...

Air quality, radiation pollution, and water pollution were thekey featuresthat possess genuine challenges to the environment. Proper monitoring wasneededin such a way that the world couldaccomplish sustainable development, withkeeping a healthy society. Recently, environment monitoring is become a...

For the past few decades, owing to human activities, urbanization, and industrialization, air pollution is becoming severe across several countries. Deep Learning (DL) and Machine Learning (ML) techniques had great contribution to the development of methods in various aspects of prediction, planning...

Air is one of the most basic and important elements for human beings to survive. Clean and Sound air is the key to a good and healthy life. But nowadays in city life it has become the most threatening factor. Pollution of air has become the most concerning and affected issue now for us. As time goes...

The greater area comprising the Attica peninsula and the Saronic Gulf is greatly influenced by various local circulation types. During winter months, moderately high air pollutants concentrations are observed when the prevailing condition is either stagnant or a weak southern flow. The case studied...

The level of air pollution increased in urban areas due to local atmospheric conditions and dispersion of various air pollutants. In this study, the air quality index was carried out in four places in the urban zone and investigated the seasonal variation of PM2.5, PM10, SO2, NO2, and O3 over one...

Air pollution related problems, such as acidification, air quality and ground-level ozone, are recognized as some of the important problems facing the people of the Czech Republic, whose health is damaged by impacts of air pollutants. Also the impacts of these air pollutants on human health, forests...
