Estimation of greenhouse gas emissions from landfills: application to the Akrotiri landfill site (Chania, Greece)
General
Landfilling is one of the most common ways of municipal solid waste (MSW) disposal in developing countries. Air pollutants emitted from landfills contributes to the emission in the atmosphere of greenhouse gases and cause serious problems to the human health. Methane emission from landfill is...
A spatially allocated emissions inventory for Cyprus
General
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...
An air quality management system for Cyprus
General
The new Air Quality Directive (2008/50/EC) encourages the introduction of modelling as a necessary tool for air quality assessment and management. Towards this aim, a new Air Quality Management System (AQMS) has been developed and installed in the Department of Labour Inspection of the Republic of...
Relationship between airborne microbial and particulate matter concentrations in the ambient air at a mediterranean site
General
The relationship between the viable airborne bacterial and fungal concentrations and the respirable particulate matter with aerodynamic diameter less than 10 μm (PM10), 2.5 μm (PM2.5), and 1 μm (PM1) in the ambient air was studied. An Andersen six stage viable particle sampler and a MAS 100 sampler...
Atmospheric PM10 particle concentration measurements at central and peripheral urban sites in Athens and Thessaloniki, Greece
General
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...
Polycyclic aromatic hydrocarbons (PAHs) in fine and coarse particles
General
About 140 samplings of fine and coarse particles were gathered during the year 2006 in Kozani that represent an urban area surrounded by opencast coal mining. A low volume dichotomus sampler has been used to trap suspended particles. The filters used were teflon, which are ideal for analysis in the...
Size distribution and chemical composition of airborne particles at Akrotiri Research Station, Crete, Greece
General
Particulate matter measurements were performed at the Akrotiri research station on the island of Crete (Greece) using an 8-stages Andersen non-viable impactor. The main purpose of the current work was to measure the ambient levels of PM10 particulate matter as well as the concentrations of metals...
Dispersion modeling of odours emitted from pig farms: winter-spring measurements
General
One of the main environmental impacts of pig farms are the swine odours emitted from the various stages of the process. The main cause of odour emissions from pig farms are the anaerobic processes in manure. Numerous factors affect odour emissions such as diet, manure management and manure age. The...
Numerical modelling of flow structures over an industrial site: effect of the surrounding buildings on dust emissions
General
In this paper, three-dimensional numerical simulations are used to simulate the wind flow structure over coal stockpiles of a real configuration of a power plant. Two configurations are tested for various wind directions: the first one without representing the buildings and the second one with the...
Optimizing the performance of Kalman filter based statistical time-varying air quality models
General
In this study, the Bayesian approach is proposed to estimate the noise variances of Kalman filter based statistical models for predicting the daily averaged PM10 concentrations of a typical coastal city, Macau, with Latitude 22°10’N and Longitude 113°34’E. By using the measurements in 2001 and 2002...
Particulate matter investigation in indoor environment
General
Particulate matter is one of the most important indoor air pollutants involved in a number of adverse health effects, such as premature deaths and increased mortality of infants and other parts of sensitive population. This paper focuses on investigation of metal substances of suspended as well as...
Indoor / outdoor PM levels and EC surrogate, at typical microenvironments in the Athens area
General
The aim of the present work was to characterize particulate matter (PM) and elemental carbon (EC) indoor and outdoor concentration levels in the Athens area and to examine the contribution of ambient air to the observed indoor levels. 24-hr simultaneous indoor and outdoor PM10 and PM2.5 measurements...
Contribution of traffic and tobacco smoke in the distribution of polycyclic aromatic hydrocarbons on outdoor and indoor PM2.5
General
Traffic emissions and tobacco smoke are considered two main sources of polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air. In this study, the impact of these sources on the level of fine particulate matter (PM2.5) and on the distribution of 15 PAHs regarded as priority pollutants by...
