An initial GIS data base has been assembled in 2001 covering the various parameters related to the Nestos river basin and its delta. This data set is being used for water resources modelling purposes within the frame of the multinational PROMENES initiative. The initial data gathering has produced a...

This work illustrates the use and some related results of Artificial Neural Networks (ANNs) for data quality control of environmental time series and for reconstruction of missing data. ANNs are applied to the following problems: i) short and medium-term predicting of air pollutant concentrations in...

Air pollution forecasts in major urban areas are becoming a problem concerning the day to day environmental management for city authorities. This paper describes the development of an application to forecast the peak ozone levels with the aid of meteorological and air quality variables, in the...

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...

In the present study seasonal changes of chlorophyll content and storage substances related to the metabolic response of the widespread, evergreen plant oleander (Nerium oleander) to air pollution were investigated. Mature leaves of oleander shrubs, grown at five sites of differing levels of air...

In this paper, a detailed spatial allocated emissions inventory for Cyprus is presented. Topdown and bottom-up methodologies are implemented and emissions are estimated from all anthropogenic sources for the reference year 2002 with the aid of state-of-the-art algorithms. Emission factors...

The analysis of the PM10 particle measurements at the two major urban areas of Greece, Athens and Thessaloniki, showed that the mean monthly PM10 concentrations at the central urban stations, are on the average about twice as high than the corresponding ones at the examined peripheral stations. The...

Globalization and liberalization polices of the government of India have increased the number of road vehicles nearly 92.6% from 1980-81 to 2003-2004. Therefore to know whether there is effect of increase of industrialization in the urban areas like Pune (18° 32′N, 73° 51′E); Mumbai (18° 55' N, 72°...

The Mn and Pb of the total suspended particulates (TSP) in totally 95 1-h samples and As, Cd, Mn, Ni and Pb in totally 29 24-h samples have been determined by flameless graphite furnace atomic absorption spectrophotometry. The monthly TSP for July 1992 contained Mn and Pb 0.033 and 1.25‰ in downtown...

According to the actual European context, including the development of risk free residential and industrial areas, the main demand lies in instant, accurate and elaborated information regarding environment quality and pollution risks. This paper presents a conceptual architecture for a versatile...

The paper describes the development of a fast and easy-to-use qualitative tool for preliminary assessments of urban air quality related to road traffic. The tool is particularly aimed at the ability and budget of local government. It uses a novel interaction matrix-type methodology combined with...

In this paper, we present the estimate and results of measurement of air pollution in Béjaia city in Algeria. We used an enclosure of 0,80 m3 for the collection of gases directly on the outlet side of the tailpipe of the vehicles. A three-gas detector (MX21 plus), introduced inside the enclosure...

Urban air quality nowadays is one of the major environmental issues, due to its impact to various health problems, caused by the daily exposure of the population in dangerous air pollutants. The highest levels of air pollutants are usually observed in street canyons, emitted by urban traffic. To...

Atmospheric aerosols play an important role in local, regional meteorology, visibility, air pollution, haze formation and energy balance of radiation. These processes influence the climate directly or indirectly. Therefore, for increasing importance of aerosols in understanding the various...

Probability density functions (pdf) have been used in the analysis of the distribution of pollutant data, for examining the frequency of high concentration events. There have been very few studies on the concentration distribution of PM in urban areas. The distribution of PM concentrations has an...

Several epidemiological studies have shown an association between particulate air pollution and health effects. Suspended particulates and more specifically the inhalable PM10 fraction appear to cause respiratory health effects and heart diseases. Furthermore, particulate pollution is of paramount...
