3.1 Estimation of population time activity data and analysis
  • Collecting of time activity data for children and elderly people and analysis
3.2 Inter-comparison (intra- and inter-laboratory PAH measurements and intra-laboratory particulate sampling)
  • Reliable procedures for determining carcinogenic PAHs associated to particulate collected at low-volume conditions.
  • Homogeneity assessment for PAH data bases obtained by the Partners with the same methods and/or with the different methods processed.
  • Reliable procedures for determining EC/OC associated to particulate collected at low-volume conditions.
  • Preliminary data on BaP, PAH, EC/OC and gaseous pollutants in indoor and outdoor environments in Rome.
3.3 Field campaigns of particulate PAH (indoor, outdoor and personal exposure evaluations and data analysis), and ancillary measurements concerning gaseous toxicants and the PM2.5 chemical components including EC/OC
  • carcinogenic PAH associated to PM2.5, measured in 10 to 20 indoor and outdoor microenvironments lying in the urban Rome area; two data sets will be collected both in summer and in winter;
  • EC/OC, measured in 3 indoor and outdoor environments lying in the urban Rome area; two series will be collected both in summer and in winter;
  • airborne PM2.5 chemical composition, measured indoor and outdoor at 3 locations lying in the urban Rome area
  • gaseous toxicants (O3, NO2, monoaromatic hydrocarbons), measured as average contents during the summer and winter campaigns at all sites studied;
  • Daily collection of PM10 and PM2.5 for PAHs determination in the Regional Environmental Network (REN) stations;
  • carcinogenic PAH associated to PM2.5, monitored for 5 to 7 exposed volunteers by means of personal measurements.
3.4 Collection of meteorological data in the studied region
  • Collection of hourly surface and upper air meteorological data for one year at 4 stations
4.1 Collection of raw emission inventories and their upgrading
  • To develop a state-of-the-art PAHs emission inventory for the city of Rome and its surrounding area
4.2 Definition of simulated areas, collection of cartographic data and traffic data for Rome
  • Definition of the air quality modelling computational domains which identify EXPAH target areas.
  • Construction of cartographic and traffic data bases to support modelling and later analysis activities.
4.3 Traffic emission calculation

  • Hourly average pollutants emissions on Rome city road network
4.4 Upgrading of particulate PAHs speciation profiles and integration of all emission inventories and spatially, temporally and chemically disaggregation.
  • Production of hourly gridded emissions of PAHs and all the other pollutants covered by European legislation as needed by air quality model
4.5 Upgrading of model PAHs transformation processes and simulation of meteorology, emission, dispersion, transformation and deposition of outdoor pollutants
  • Assessment of the PAHs atmospheric reactions processes implemented within the chemical transport model FARM.
  • Evaluation of outdoor hourly average concentrations and deposition of PAHs and of all the other pollutants considered by the atmospheric chemistry simulations, over a time period of one year.
5.1 Statistical analysis of indoor and outdoor PM2.5, PAHs, EC/OC and corresponding i/o ratios.
  • quantitative characterization of PAH indoor outdoor relationships

5.2 Developing of a microenvironment infiltration model
  • To develop a quantitative model for PAH infiltration, accounting for particle size distribution and different types of microenvironments. The model describes the expected indoor concentration of PAH compounds when the type of the building and microenvironment and the outdoor concentrations are known.
5.3 Developing of an exposure model
  • To develop an exposure model which integrates the outdoor PAH concentrations and PAH infiltration indoors with population time-activity, including time spent indoors and in traffic to estimate the actual exposure levels generated by the emissions and atmospheric dispersion processes.
5.4 Simulations of population exposure
  • To produce hourly maps of PM2.5 and PAHs exposure for the target population living in the city of Rome, using results produced by the chemical transport model (action 4.5) and exposure model (action 5.3).
5.5 Optimization of model results with actual population exposure
  • To obtain PAH outdoor maps more related to the measured PAH concentrations by means of statistical optimization models
6.1 Evaluation of the short-term impact of PAHs and other pollutants on natural and cause specific mortality
  • To evaluate the short-term relationship between concentrations of source specific air pollutants and natural and cause-specific mortality.
6.2 Evaluation of the short-term impact of PAHs and other pollutants on emergency hospital admissions
