The long term impact of Pm2.5 on mortality in Ho Chi Minh city, 2018

Abstract

Background: Air pollution is a risk factor for non-contagious diseaseswith an estimated 7 million deaths per year¹. The average concentration of dust in 24 hours per year through 2013 to 2017 in Ho Chi Minh City exceeded the WHO standard's value limits.

Methodology: The study aims to build the PM_2.5 spatial concentration map and assess the long-term health impact of PM_2.5 on all-cause mortality (heart, respiratory, lung cancer, respiratory cancer, etc.) in Ho Chi Minh City, Viet Nam 2018. We conducted a health impact assessment (HIA) study with collecting various types of data, including national community mortality (named as A6 mortality); geographic data, population, and environmental monitoring using low-cost sensors AirBeam2.

Result: 29.176 deaths from all causes were included in this study in which PM_2.5 was considered to have a long-term impact on 1.770. We found an increase of 1μg/m³ in PM_2.5 in yearly concentration was associated with an increase of 45 people of all-cause deaths.

Conclusion: The study provided scientific evidence on the significant long-term health effects of PM_2.5 on people living in Ho Chi Minh City. Precautions are necessary to protect people's health and minimize the burden of mortality caused by PM_2.5.
