COMEAP Report: The Mortality Effects of Long-Term Exposure to Particulate Air Pollution in the United Kingdom(2010)
COMEAP Report 2010
The Mortality Effects of Long-Term Exposure to Particulate Air Pollution in the United Kingdom 
Original 2010 report from the Committee on the Medical Effects of Air Pollutants. This report stated the original 29000 deaths attributable to Particulate Matter figure.
The report highlighted the following caveats:
"These effects can be expressed at the population level in terms of life expectancy, and on loss or gain in life years. The burden can also be expressed in terms of deaths occurring in a specified year across the population."
"As everyone dies eventually no lives are ever saved by reducing environmental exposures – deaths are delayed resulting in increased life expectancy."
"These measures are averages or aggregates across the population; it is not known how the effects are distributed among individuals."
