Industrial Air Pollution and the Permitting Procedure of three thermal Power Stations of the Public Power Corporation (P.P.C.) S.A. in Greece
© Aristotle University of Thessaloniki (6/2009)
The three thermal Power Stations of the Public Power Corporation (P.P.C.) S.A. located in the Prefecture of Kozani caused significant air pollution problem due to their operation. This paper presents the Greek Ombudsman’s (GO), investigation for the legality of the Plants operation framework up to the end of 2005. Three main problems were revealed during the investigation. i. Air pollutant (and especially PM-10) emissions were above the admissible level on a systematic basis. ii. The power stations approved environmental terms had expired since 2002 and no renewal had taken place. Thus the industries operation was illegal. The issue was that the new environmental terms approval was delayed, because P.P.C. could not implement the Best Available Techniques that should have been incorporated in the terms decisions, according to the IPPC (96/61/EC) Directive requirements. iii. The three industries operation license was very close to expire and no progress was made on its renewal.

Application of satellite remote sensing and sun-photometers to determine the aerosol optical thickness over Cyprus
© Aristotle University of Thessaloniki (6/2009)
Urban air quality has traditionally been monitored with networks of ground monitoring stations and the use of models that evaluate emissions and predict changes in air quality at discrete points. The increasing availability of earth observing satellite systems together with advances in digital image processing techniques provide a new avenue to monitor urban air quality at a citywide and regional scale.

CFD study on the performance of a cyclone with tangential air inlet operating at high pressure
© Aristotle University of Thessaloniki (6/2009)
A computational fluid dynamic (CFD) study on the pressure drop and collection efficiency of a cyclone separator operating at high pressure (1, 6, 25 and 60 atm) was conducted. The cyclone was a high efficiency Stairmand, with a body diameter (Dc) of 0.3m and tangential air inlet. The inlet velocity was 20 m/s in all cases. Particles with diameters between 0.5 and 10 m and densities of 1500 and 3000 kg/m3 were used. The particle motion was simulated in a Lagrangian frame.

The performance of fiber filters was evaluated according to the penetration of nano-sized particles in homogeneous and heterogeneous fibers acting in aerosol filtration. Two fiber filters were utilized: a polyester fabric filter and a cellulose HEPA filter.

Comparison between MM5-CMAQ and WRF/CHEM PM10 and PM2.5 concentrations for an episode in Germany during Winter, 2003
© Aristotle University of Thessaloniki (6/2009)
High elevated PM10 and PM2.5 concentrations were measure in several monitoring stations locaten mainly in the North part of Germany during the Winter period of 2003. In particular three peaks in February and March are clearly identified. The average measured concentrations showed up to five times higher values (peaks) compared with normal concentrations for PM10 and PM2.5.

Genotoxic and oxidative effects of PM2.5 organic extracts from personal respirable dust samples of security guards working in two sites of Rome(Italy), were investigated. The PM 2.5 samples were collected at site 1 and site 2 characterized by moderate and high traffic intensity respectively.

Statistical analysis of PM10 data in urban region of Volos, Greece
© Aristotle University of Thessaloniki (6/2009)
Hourly measurements of particulate matter with an aerodynamic diameter less than 10 μm (PM10) recorded in the urban area of Volos, a medium-sized Greek coastal city, for a seven-year period, 2001-2007, are analysed. The main objective of this work is to study the typical behaviour of this air pollutant concerning diurnal and seasonal variations and meteorology dependencies.

Size distribution of metallic elements in particulate matter from a busy urban area
© Aristotle University of Thessaloniki (6/2009)
This study analyzed size distribution characteristics of metallic elements in airborne particulate matter (PM) collected from a busy urban area in a metropolitan city, Korea. PM samples were collected using an eight-stage cascade impactor during the spring and summer of 2008. Concentrations of the different PM size categories were determined using a micro-balance gravimetric method. Metallic elements on each PM filter were extracted ultrasonically using a 1:1 mixture of hydrochloric and nitric acid.
