These hyperlocal pollution episodes that trigger greater exposures, especially to ambient air pollution, can cause increased vulnerability and burden of disease. The 2019 subnational burden of disease study estimated that more than 10·4% of total deaths (approximately 980 000) and 6·7% of total disability-adjusted life years (approximately 31·1 million) are associated with exposure to ambient PM 2·5 .
