Mapping air pollution: the city of Thessaloniki - Greece case study
© Aristotle University of Thessaloniki (6/2009)
Air pollution is a global problem that affects natural ecosystems and poses a significant human health risk. The main objective of this study is the evaluation and mapping of air pollution levels. This paper examines traditional and new techniques and processes of mapping a geographic phenomenon like air pollution, which requires spatial methods and algorithms.

Publics’ attitude on air pollution in the city of Thessaloniki, Greece
© Aristotle University of Thessaloniki (6/2009)
The present work investigates the major environmental problem of air pollution that more or less occurs in the cities, based on publics’ perception. A case study was carried out in the city of Thessaloniki, Greece, in order to present and evaluate the publics’ attitude on air pollution levels in the city.

Development of a new photochemical mechanism suitable for air pollution simulation in Greece and comparison with four known mechanisms
© Aristotle University of Thessaloniki (6/2009)
In this paper we present a new photochemical mechanism, GGCM-EX, which is based on ambient concentration and emission data occurring in the atmosphere over Athens – Greece. Taking into account the most important organic species for this area as well as their secondary products a new photochemical mechanism was developed including 67 chemical species and 174 chemical reactions.

Characterization of particulate matter emitted due to production proesses of sanitary wares and tiles in ceramic factories
© Aristotle University of Thessaloniki (6/2009)
A high-volume air sampler was used to collect particulate matter from different departments of a sanitary ware factory, from a tile factory and from the surrounding industrial area of Sindos, Thessaloniki. The purpose of this is to characterize the amount and composition of total suspended particles (TSP) in the atmosphere inside and outside of ceramic industries.

Peroxyacetil Nitrate (PAN) in urban atmosphere: levels and behavior

The peroxyacetil nitrate (PAN) is the most characteristic photoxidant, which is produced from NOx and reactive hydrocarbons in photochemical smog. In this paper daily PAN temporal evolution are compared with the Ox variable in different meteorological conditions.

Development of an Environmental Management System according to EMAS in a very large industrial installation: Case study
© Aristotle University of Thessaloniki (6/2009)
The Design, Development and Implementation of an Environmental Management System, according to the EMAS European Regulation (761/2001), in a very large industrial complex in Greece (Petroleum Refinery), is presented. This complicated project concerned the Environmental Management of the operation of a great industrial complex with activities characterized by their significant environmental impacts. It was implemented with the co-operation of three collaborating engineering-consulting companies, as well as with the continuous and lasting cooperation of the Management and personnel (administrative and technical) of the industry.

Toxicity of fine and coarse atmospheric particles using Vibrio fischeri
© Aristotle University of Thessaloniki (6/2009)
In the present study, the toxicity of fine (<2.5m) and coarse (2.5-10um) particulate matter was determined using a rapid and cost-effective bioluminescence assay, the Microtox bioassay. Samples were collected in the city of Kozani which is a heavy industrialized area in the north-western part of Greece and characterized by complex topography. Near Kozani, lignite power stations (PS) operate with a total installed generating capacity of more than 4.7 GW. These PS contribute to about 57% of the total electrical energy produced in Greece. The lignite used by these power stations is mined in the nearby open-pit mines. Dust emissions seem to be the most serious problem in the area, as the measured ambient concentrations of suspended particles are at high levels and exceed local and international standards.

Assessing particulate matter emissions from a copper mine crushing process

Copper mining industry is the main economical sector in Chile, being also one of the most important regarding solid waste and atmospheric emissions generation. In addition, crushing processes in mining industry generate large amounts of fine particulate matter to the working and atmospheric environment.

Biogenic carbon accounting in LCAmodelling: comparison of different criteria
© European Compost Network ECN e.V. (10/2008)
In this study we have tested 5 sets of criteria for assigning GWPs to the C flows in waste management system. A simplified model was established for the waste management system and the surrounding industries represented by the pulp and paper manufacturing industry, the forestry industry and the energy industry.

Measurement Results on Full Scale Field Experiment using Optical Fibre Detection Methods
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (10/2007)
Both active and passive temperature measurement methods have demonstrated their functionality to locate leaks in dams. However the sensibility of measurements with respect to external parameters such as air temperature or solar radiative flux has not been well investigated.
