Detailed Narrative Description of Project:
In this study, an attempt has been made to evaluate the health impacts of SPM. The field surveys data of pollution concentrations, census data, and epidemiological data have been combined to assess overall health effects and to estimate the consequent economic loss in monetary term. In this work risk assessment of PM10 has been performed for Dhaka city. An evaluation of economic loss due to adverse health effects has also been made. Results from this analysis show that the number of excess death per annum due to PM10 pollution in Dhaka is 10350. For PM10 pollution, this study predicts about 74 thousand cases of chronic bronchitis, about 70 million cases of restricted activity days, about 14 thousand cases of respiratory hospital diseases, over 286 thousand emergency room visits, about 2.8 million cases of asthma attacks and over 220 million respiratory symptom days. In case of economic evaluation of impacts, it has been found that over taka 83 billion comes as the total costs for excess death case, over taka 20 billion as cost of chronic bronchitis, 5 million taka as cost of restricted activity days, taka 153 million as cost of respiratory hospital diseases, taka 114 million as cost of emergency room visits, taka 42 billion cost of asthma attacks, taka 11 billion as cost of respiratory symptoms days. Thus the total cost came out to be about taka 124 billion, which shows a tremendous loss to the economy. The economic cost of this sickness and death is estimated to be $ 124 million per year or 3-4 % of GDP. The AQI level in Dhaka, which represents the status of air quality and is associated with health effects, was calculated using the methodology developed by US EPA. The study finds that AQI value for most of the pollutants before 2003 was above 100 (e.g. AQI for April 2002 was 210 for NOx), but in 2003 AQI value reduced largely (e.g. AQI for April 2003 was only 32 for NOx). This study will provide useful information on the impacts of air pollution on the national economy as well as planning and decision taking processes regarding air pollutions management.
