Mesoscale modeling of combined aerosol and photo-oxidant processes in the eastern Mediterranean
International audienceParticulate matter and photo-oxidant processes in the Eastern Mediterranean have been studied using the UAM-AERO mesoscale air quality model in conjunction with the NILU-CTM regional model. Meteorological data were obtained from the RAMS prognostic meteorological model. The modeling domain includes the eastern Mediterranean area between the Greek mainland and the island of Crete. The modeling system is applied to study the atmospheric processes in three periods, i.e. 13?16 July 2000, 26?30 July 2000 and 7?14 January 2001. The spatial and temporal distributions of both gaseous and particulate matter pollutants have been extensively studied together with the identification of major emission sources in the area. The modeling results were compared with field data obtained in the same period. Comparison of the modeling results with measured data was performed for a number of gaseous and aerosol species. The UAM-AERO model underestimates the PM10 measured concentrations during summer but better comparison has been obtained for the winter data
Particulate matter exposure and dose relationships derived from realistic exposure scenarios
Day-averaged outdoor aerosol concentrations from fixed ambient air monitoring stations are associated with the daily lung dose of an individual and the consequent health effects in most studies. The applicability of such measurements for dose assessment is evaluated in this study by comparing the estimated total and regional lung doses using the above concentrations, continuous (hourly) or day-averaged, to the dose derived from actual exposure. Dosimetric calculations are performed using experimentally determined indoor and outdoor concentrations during realistic exposure under variant physical exertion in both environments. The results show that the daily dose can be closely estimated by day-averaged data. © SAGE Publications 2008

Estimation of human exposure and dose using an environment and health decision support tool
Summarization: Respirable particle concentration measurements were performed indoors and outdoors at work
(Technical University of Crete), indoors at home (an apartment in the vicinity of the University
Campus) and during transition from the apartment to the Campus, and the opposite, and a detailed
activity diary was kept. In addition, PM10 concentration and size distribution measurements were
taken indoors and outdoors the apartment. The STEDOM decision support tool was used to estimate
the exposure and dose at home, work and in transit for a healthy adult Caucasian female. The
STEDOM tool and analysis of the measurement data and modelling results are presented. Enhanced
exposure occurred at home whereas the average dose rate was higher at workΠαρουσιάστηκε στο: 9 th International Conference “Protection and Restoration of the Environment I

Chemical characterization of ambient particles in Oslo metropolitan area and received human dose
Summarization: Indoor-outdoor measurements of particulate matter mass concentration and size distribution have
been performed in a residential background area in Oslo, Norway, and the samples were analysed
for various chemical species. Based on the distributions and concentrations the dose of each
component in the human respiratory tract was calculated for a healthy adult Caucasian male worker
using the Human Respiratory Tract Model of the ICRP. Regional lung doses were compared for
various chemical species. The highest dose value was observed in the alveolar region of the lung for
organic airborne particles.Παρουσιάστηκε στο: International Conference for the Protection and Restoration of the Environment VI
