Exposure(GIS based)

Health effects(based on dose/response curves)

The tools developed consist of two modules (TEX & HIT) to provide two sets of health-related indicators:

• exposure measurements: TEX operates within ArcGIS and for population groups defined by the users according to different features. TEX calculates the exposure of predefined groups along the scenario duration (from 1 hour to 1 year) of considered case study.

• health effects: HIT calculates attributable mortality or morbidity, relative risk, disease-adjusted life-years, for different age / social groups related to air pollution; output for noise and crashes are also available.
