UBDPolicy: Exposure-response functions of the correlated environmental exposures green space, noise, and air pollution for quantifying mortality burden in health impact assessment

Environmental health impact assessments (HIA) on green space, air pollution (fine particulate matter (PM_2.5) or nitrogen dioxide (NO₂)), and noise use exposure–response functions (ERF) based on single-exposure models from epidemiological studies, not accounting for potential confounding by other commonly correlated exposures. UBDPolicy assessed differences in ERFs between single- and multi-exposure models for calculation of joint health impacts in HIA.
