Characterisation of Urban Air Quality - Indoor/Outdoor Particulate Matter Chemical Characteristics and Source-to-Inhaled Dose Relationships

Measurements:
Summer/Winter 2001 – 2002

• Measure fine particle and photochemical gasses physico-chemical characteristics at indoor/outdoor

- 6 urban areas (Athens, Oslo, Milano, London, Hanover, Prague
- 22 residential places (Measurements both at summer/winter)
- Detailed chemical analysis, bioaerosol contribution

• Characterize the factors affecting the indoor/outdoor PM characteristics (mass/number/chemical composition/size distribution)

- Measurements
- Microenvironmental modelling

Measurement Study at residential places across Europe (Urban sites) during summer and winter

• Evaluation of existing information from previous studies.

• Online (SMPS, APS, aethalometer) and Offline (PM10, PM2.5, impactors, denuder/filter pack system, diffusion tubes, bioaerosols, PAHs, VOC) measurements.

• Meteorological measurements, infiltration (SF6).

Chemical Analysis - Database Construction

• Analysis of the field measurements (Ion Chromatography, EC/OC, Atomic absorption spectrometry, PIXE, INAA, GC/MS, LC/MS)
• Bioaerosol contribution on the PM mass indoors (Culture-based methods, Microscopy, PCR-based)
