UIN HL4217, tabled on 19 December 2016

There was an estimate of 600 deaths across the United Kingdom over the 10 days of High and Very High air pollution compared to around 300 associated with typical particulate (PM2.5) air pollution levels.

The mortality estimates are calculated based on published epidemiological exposure response coefficients. It is not possible to determine which individuals were impacted by this episode specifically, nor the length of time that deaths were brought forward by.
