PM-DOSE · Human exposure to particulate matter and source-to-internal dose relationships

Final Activity Report Summary - PM-DOSE (Human exposure to particulate matter and source-to-internal dose relationships)

Measurements - Continuous outdoor measurements at Akrotiri research station (TUC Crete campus): - continuous meteorological data measurements (temperature, humidity, wind speed and direction); -particulate matter (PM10 or PM2.5) concentration measurements using automatic beta radiation attenuation monitor - continuous sampling of atmospheric ozone with ambient ozone monitor. - Results of PM10 and PM2.5 levels in the Eastern Mediterranean and their seasonal variations have been published in journal water, air and soil pollution and at the conference PRE8. - Comparative measurement campaigns with various PM instruments at Akrotiri research station: - meteorological data measurements; - measurements of atmospheric ozone with ambient ozone monitor; - PM10 comparative measurement with automatic beta radiation attenuation monitor and low volume sequential particulate sampler and low volume reference sampler. - Results of comparative measurement have been published in journal water, air and soil pollution. - Measurement campaign at Akrotiri research station with off-line and on-line instruments: - meteorological data measurements; - measurements of atmospheric ozone with ambient ozone monitor; - PM2.5 measurement with automatic beta radiation attenuation monitor; - PM10 measurements with sequential particulate sampler and reference sampler; - particle number size distribution measurements with Andersen impactor - gravimetric, SMPS (CPC + LONG DMA) and FCE (with SHORT DMA) - online particle counters. - Two measurement campaigns in a detergent factory at the Athens metropolitan area - cooperation with Demokritos Research Centre (Athens): - measurements of PM in production hall of detergent factory in Athens (the periods of production, the periods of maintenance and the time without any activities) using two real-time photometric monitors Dusttrak, Andersen non-viable impactor, Berner impactor, PM2.5 virtual impactor head, sequential particulate sampler with PM10 head, Dataram4, PDR1200, PDR1000. - Results were published at the conference PRE8 and in the journal water, air and soil pollution. Focus - measurement of simulated indoor sources: - indoor and outdoor PM measurement using Dusttrak and P-Tra; - measurement of particle size distribution with Scanning mobility particle sizer (SMPS) and Faraday cup electrometer (FCE); - continuous monitoring of indoor conditions (temperature and relative humidity) using Tinytag instrument. - Results were published at the conference EAC2007. Data analysis: - statistical analysis for all the collected data sets; - analysis of PM entering human respiratory system for outdoor measurements and indoor measurements with simulated indoor sources. Modelling: - cooperation with PhD students on improvement of the AEROEXPDOSE model for calculation of respiratory tract doses of aerosol particles in human body; - development and improvement of algorithm for merging aerosol particle size distribution (AMANpsd) data from multiple instruments (SMPS, nano-SMPS and APS); - code for rearrangement of output data from FCE; - code for calculation of penetration efficiencies of sampled particle through sampling tubing.
