In this study current status of the ambient air quality in the main cities of the Pearl River Delta region was investigated. Two special administrative regions (Macau and Hong Kong) and three major cities of Guangdong (Guangzhou, Dongguan and Foshan) were selected for analysis according to their...

The present study is carried out to explain the presence of large concentrations of SO 2 in atmosphere of Pakistan during June, 2011. Large volcanic eruptions are a major source of greenhouse and trace gases. The eruption of Mount Nabro in June, 2011 injected large amount of SO 2 into stratosphere...

Dust pollution is a major problem in opencast mines. Many activities are associated with generation of dust that makes a cloud of pollutant at the work environment and the surrounding areas. Activities as drilling, blasting, transportation, surface miner etc. are the principle sources of generation...

The assessment of the air quality of indoor environment where people usually spend extended time periods, especially for sensitive population groups such as patients during their hospitalization, is of major importance. Ensuring a safe level of air quality in these indoor environment serves as an...

This study examined the toxicity potential of total suspended particulate in the airshed of a haulage vehicle park located in a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. It has an approximate area of 0.6 km2. Ambient air total suspended particulates (TSP)...

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...

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 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...

Two three dimensional Eulerian air quality models, PMCAMx and UAM-AERO are used to predict the concentrations of various pollutants in the Greater Athens Area (GAA) during the episode of June 22-26, 2003. The predicted levels of gases and aerosol pollutants are compared with measured concentrations...

This study reports particulate matter levels of various size fractions (PM10, PM2.5, and PM1) and identify their controlling factors, in various locations over Greece. It combines long-term data sets involving particle concentrations as measured in the island of Crete in the Eastern Mediterranean...

In this study, the relationship between inhalable particulate (PM10), fine particulate (PM2.5), coarse particles (PM2.5-10) and meteorological parameters such as temperature, relative humidity, solar radiation, wind speed was statistically analyzed and modeled for the urban region of Patras during...

The intrusion of salt wedge in rivers is a natural phenomenon, which occurs in many estuaries. Saline water tends to propagate upstream from the river mouth, due to the limited freshwater and the tidal and density currents developed, resulting in deterioration of water quality in the lower river...

The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages...

Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...

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...

The toxicity of a chemical substance in a workplace depends on both its physical and chemical properties, the level of concentration in the breathing air, as well as, the duration of the exposure. In order to ensure healthy conditions at workplace, international organizations, such as the World...

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 EU directive (2000/60/EC) known as the Water Framework Directive (WFD), identifies new methodology for monitoring and improving of surface water quality in the territory. This includes controlling land-based pollutants as well as defining the constraints for territorial planning. It is...
