Estimating causal effects of local air pollution on daily deaths: Effect of low levels

While many time series studies have established associations of daily pollution variations with daily deaths, there are fewer at low concentrations, or focused on locally generated pollution, which is becoming more important as regulations reduce regional transport. Causal modeling approaches are also lacking. The objective of the study was to use causal modeling to estimate the impact of local air pollution on mortality at low concentrations.
