Spatial Assessment of Health Economic Losses from Exposure to Ambient Pollutants in China

Abstract

Increasing emissions of ambient pollutants have caused considerable air pollution and negative health impact for human in various regions of China over the past decade. The resulting premature mortality and excessive morbidity caused huge human economic losses to the entire society. To identify the differences of health economic losses in various regions of China and help decision-making on targeting pollutants control, spatial assessment of health economic losses due to ambient pollutants in China is indispensable. In this study, to better represent the spatial variability, the satellite-based retrievals of the concentrations of various pollutants (PM 10 , PM 2.5 , O 3 , NO 2 , SO 2 and CO) for the time period from 2007 to 2017 in China are used instead of using in-situ data. Population raster data were applied together with exposure-response function to calculate the spatial distribution of health impact and then the health impact is further quantified by using amended human capital (AHC) approach. The results which presented in a spatial resolution of 0.25 • × 0.25 • , show the signification contribution from the spatial assessment to revealing the spatial distribution and variance of health economic losses in various regions of China. Spatial assessment of overall health economic losses is different from conventional result due to more detail spatial information. This spatial assessment approach also provides an alternative method for losses measurement in other fields.

Investigating the Relationship between Air Pollutants and Meteorological Parameters Using Satellite Data over Bangladesh

“…In recent decades, air pollution has become the prime concern of most nations in the world due to the intensification of human activities and adverse meteorological situations. Severe air pollution has caused negative health impacts and resulted economic losses [1,2]. Several studies have explored multiple human health issues caused by air pollution, such as cardiovascular and pulmonary ailments [3][4][5], diabetes and high blood pressure [6], premature deaths [7], mental health problem [8], etc.…”
