AB  - Currently, no adequate methodology exists to assess the NO2 health impacts at an EU-wide level. To a large extent this is attributed to the level of detail required in the NO2 concentration assessment at EU-level due to the strong spatial gradients for NO2 around roads. In this contribution we present a sensitivity analysis of the major sources of uncertainty in such an EU-wide health impact assessment for NO2. We do this by means of a number of bottom-up NO2 assessment maps contributed through the FAIRMODE composite mapping platform. We investigate the impact of the spatial resolution of the NO2 assessment, the available dose response curves and a number of ancillary datasets such as gridded population. We find that the largest source of uncertainty is found in the divergence between the different CRF’s available, in particular the choice of a ‘cut-off’ or ‘threshold’. For some cities, such as London, the difference is relatively small. However, the difference for smaller cities, such as Klagenfurt can go up to a factor of 6. Spatial resolution of the air quality maps and population maps is an important factor and depending on the concentration response function, the sensitivity is stronger. This work has been performed in the framework of the DG-ENV service contract 070201/2015/SER/717473/C.3, the conclusions of which contributed to the development of an EU-wide high resolution NO2 exposure assessment methodology.
