About the projectSP2 - Air Quality Exposure    August 22, 2017  English (United States) English (United Kingdom)
Overview of SP2: Air quality and exposure
 

The overarching aim of SP2 is the assessment of urban concentrations and human exposure to various air pollutants with emphasis on particulate matter, by using existing measurements, targeted measurement campaigns to be conducted in TRANSPHORM, and integrated air quality and exposure modelling systems.

In particular, SP2 will provide both monitoring and modelling data concerning (i) the physical and chemical characteristics, (ii) the source contributions, (iii) the spatial and temporal distribution and (iv) the exposure to particulate matter. Special emphasis is focused on size-segregated data, especially fine and ultra-fine particles. Measurements  and modelling will be employed in a range of cities, with different levels of involvement.

 
 
Work packages and their objectives
 

To plan and co-ordinate all activities related to the measurement campaigns to be conducted in TRANSPHORM, as well as the collection and processing of existing measurement data and the management of these data.

To conduct measurements including extended chemical analysis of ESCAPE filter samples; the measurement of size resolved ultrafine fraction (UF) and chemical analysis of filter samples in a multiple transport urban environment, the measurement of UF and PM in varying urban transport micro-environments and the chemical analysis and size distribution of ship emissions.

To use the TRANSPHORM data and existing measurements to improve and evaluate air quality and exposure models and for source apportionment studies and to establish the spatial variations of PM fractions across  European cities feeding into SP3, 4 and 5.

To assess, and demonstrate, methodologies for determining the source characteristics and contributions of PM from transport related emissions in urban areas.

To provide urban wide assessments of the contribution of transport related emissions, including traffic exhaust, non-exhaust as well as shipping and the long-range transport of transport related emissions.

To provide feedback on the quality of the emission inventories and spatial maps of source contributions for health studies (SP1, 3).

To conduct regional scale source apportionment based on modelling studies.

To improve the existing atmospheric dispersion models for their application to transport related health assessment.

To optimise the models for their application on the urban scale and for application in SP3 for transport related health impact assessments and in SP4 for integrated assessment and measures.

To use the modelling systems and provide size resolved and source specific PM mass and number concentrations covering a range of complexities for exposure and health impact assessment in SP3 and SP4.

To develop and improve simpler and operational air quality models and systems for exposure and health impact assessment studies including establishing the distribution of exposure to transport-related, chemically speciated PM of participants in ongoing cohort studies (ESCAPE) using both the dispersion and stochastic models.

To assess the long range transport, both global and regional, of transport related pollutants and their contribution to European air quality and exposure.

To improve the quantification of European wide exposure and health assessments through improved treatment of long range transport of shipping emissions and their effects on European health;

To quantify the source contributions of transport sectors on the European scale and provision of appropriate climate couplings for future health scenario calculations.

To use global model to provide regional background levels for urban models applied in SP3 for health impact assessments, in SP4 for integrated assessment and measures and SP5 for scenario calculations.

To develop and improve models and methodologies for the determination of human exposure to transport related PM.

To use currently available deterministic and probabilistic exposure models, and couple these with dose models based on alveolar lung deposition. Data from targeted measurement campaigns in traffic micro-environments (WP2.1) will be used as inputs in the exposure models.

To integrate, evaluate and apply integrated methodologies for calculating atmospheric dispersion and population exposure and provide estimates of concentrations and exposures, both short and long term, for use in the health impact studies in SP3.

To evaluate pollutant, microenvironment, and source category specific exposures for various metrics of PM and exposures for selected other major pollutants such as NOx and NO2.

To apply the analyses to both the general population as well as to critical susceptible population sub-groups and provide quantitative results on exposure in formats that can readily be used in subsequent health impact assessments (SP3 and SP4).
