How many chinese people will die because of pollution ?

I have been impressed and extremely moved by the reading of the survey written by professors Yuyu Chen and Hongbin Li :
“Evidence on the impact of sustained exposure to air pollution on life expectancy from China’s Huai River policy (淮河)”.
This document suggest that an arbitrary Chinese policy greatly increases total suspended particulates (TSPs) air pollution caused the 500 million residents of Northern China to lose more than 2.5 billion life years of life expectancy.
The approach is based on China’s Huai River policy, which provided free winter heating via the provision of coal for boilers in cities north of the Huai River but denied heat to the south.
Using a regression discontinuity design based on distance from the Huai River, they find that ambient concentrations of TSPs are about 184 μg/m3 or 55% higher in the north.
Further, the results indicate that life expectancies are about 5.5 lower in the north owing to an increased incidence of cardio respiratory mortality.
More generally, the analysis suggests that long-term exposure to an additional 100 μg/m3 of TSPs is associated with a reduction in life expectancy at birth of about 3 years.
