This paper studies the characteristics of the heat waves that were observed in Athens, Greece since 1951. A heat wave is detected when two temperature criteria are fulfilled at the city centre: the daily maximum temperature value is at least 37 oC and the daily average temperature value is at least...

The urban planning, the buildings and covering materials of all surfaces, the distance between adjacent constructions, the height and the orientation of the buildings are some of the factors which affect the sustainable conditions in the city. This paper presents a project that aims at investigating...

This paper deals with the impacts of the current economic crisis on the temporal variation of urban traffic (during 2008-11) and consequently, the impacts on the urban air pollutant levels using as case study the city of Thessaloniki, Greece. The important temporal variations of the main economic...

The aim of this research is to study the behavior of different forest species in accordance with their ability to retain heavy metals on their leaves in order to select the most suitable species for urban and peri-urban use, which will contribute to the reduction of the continuously growing...

In this paper, the effects of the mixing ratio and particle size of coal were investigated using a thermogravimetric analysis (TGA). A method of Achar-Brindley-Sharp-Wendworth (ABSW) was applied to a simultaneous calculation of the kinetic parameters (including the apparent activation energy, the...

In order to assess the influence of reducing the speed limit from 50 km h-1 to 30 km h-1 in one-lane streets in local residential areas in large cities, real traffic tests for pollutant emissions and fuel consumption have been carried out in Madrid city centre. Emission concentration and car...

This study investigates the thermal and bioclimatic conditions in Erzurum plain and the nearby Palandoken Mountains. The data was obtained from Erzurum Meteorological Station (1758 m) and Palandoken Mountains Meteorological Station (2973 m) for 2009 and 2010 in order to compute physiologically...

This research aims to investigate the bioclimatic conditions in different ground cover types in the greater Athens area, Greece: a major street with heavy traffic (MS), an adjacent pedestrian street (PS) with irrigated plants and an urban park. Four sites were selected: one in each of the streets...

This study offers a combined analysis of personal exposure to noise and air pollution within the metropolitan centre of Thessaloniki, Greece. The area is selected on the grounds that it is considered as one of the most polluted cities in Europe, especially with respect to air pollution. An extensive...

Treatment of young landfill leachate, collected from municipal solid waste site of city of Konya, was investigated by using the Fenton process. The leachate itself showed the characteristics of pH 7.25, COD 38.2 g L-1 and BOD5 22 g L-1. Ratio of BOD5 to COD with 0.58 indicates that leachate can be...

Outdoor recreation is an important issue for people living in areas where they face problems caused by harsh climatic features like the city of Erzurum. The aim of this study was to determine the favourable features of tree species, which can grow in the city, for human bioclimatic comfort...

Abstract Spatial and temporal variation of fine particulate pollution in a complex small coastal city, Macau, was investigated by using a mobile air quality monitoring platform. Real-time street level measurements of aerosol size distribution were carried out three times per day by using an on-board...

The Attica Peninsula has experienced the rapid expansion of the Athens urban area, prior to the Athens 2004 Olympics. As a result, the distribution of pollutant sources and emission patterns has changed with a subsequent effect on the distribution of photochemical pollutants and aerosols. The...

The surface ozone is a pollutant of major concern due to its impact on receptors, at currently occurring ambient levels in many regions of the world. The aim of this work is to present the results derived from an analysis of hourly surface ozone concentrations, measured at the urban station of Volos...

Part of the attenuation of the incoming solar radiation by the atmosphere is caused by ozone absorption in the UV and visible portions of the spectrum. Ozone absorption typically accounts for only 2-3 % of the global solar radiation depletion, but it is often 10-20 % of the absorption of the direct...

Renewable water resources in Saudi Arabia are limited with groundwater as the major source for water supply. This study was conducted to assess the quality of groundwater in Almadinah Almunawarah, Saudi Arabia. Water samples were collected from 60 wells in 2010. Physical and chemical parameters were...

The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major...

Literature reports have indicated that Particulate Matter (PM) concentrations in the atmosphere over the major urban centres of Greece are high compared to other European cities of the same size. The great majority of these reports are based on measurements that have been conducted over a limited...

The PM10 airborne particle samples were collected at Shanghai from December 2003 to December 2005 in order to investigate platinum contamination in the urban air. The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The results show that the average Pt concentration in...

The concentrations of ozone, NO2 and SO2 measured by a Differential Optical Absorption Spectroscopy (DOAS) system in the city of Kozani in Northwestern Greece are presented and compared against data from a conventional ground station. This was made in order to assess DOAS performance in a...

ABSTRACT Pollution from metals and metalloids of the environment of Greece seemed to attract many researchers and elemental pollutants in air, soil and water have been determined and studied systematically during the last decade. The most recent of these studies, concerning the last five years (2003...

Seasonal variations in ecological parameters exert a profound effect on the distribution and population density of both animal and plant species (Odum, 1971). The productivity in terms of planktonic biomass in freshwater bodies is regulated by various physico-chemical factors viz., temperature...

An investigation of the quantitative and qualitative characteristics of Kosynthos river flow is presented. Four monitoring sites were established along Kosynthos river for the period October 2003 to October 2005 where discharge and water quality parameters were monitored. River flow processes have...

Uncontrolled disposal of urban and industrial wastewaters into the sea led to the fact that in mid eighties the Kasštela Bay, near the city of Split, Republic of Croatia, became one of the largest and most widely known pollution “hot-spot” areas of the Mediterranean region. The pollution of the Bay...

The effects of effluent from Thessaloniki, the second most populated Greek city, reclaimed either by activated sludge or by stabilization ponds, were studied on field-grown corn. The experimental layout was that of a split- plot design with six replications, three water qualities and two irrigation...
