Human Health Risks in Megacities Due to Air Pollution

This study evaluates the health risks in megacities in terms of death rate and morbidity due to air out taint. A new spreadsheet model, danger of Mortality/Morbidity due to Air Pollution (Ri-MAP), is apply to estimate the excess add up of deaths and illnesses. By adopting the World wellness Organization (WHO) guideline concentrations for the air pollutants SO2, NO2 and total suspended particles (TSP), concentration-response relationships and a population attributable-risk proportion concept be employed. Results suggest that or so megacities like Los Angeles, New York, Osaka Kobe, Sao Paulo and Tokyo have very baseborn excess cases in total mortality from these pollutants. In contrast, the crude numbers of cases is risqueest in Karachi (15,000/yr) characterized by a very high concentration of total TSP (670 ?g m?3). capital of Bangladesh (7000/yr), capital of Red China (5500/yr), Karachi (5200/yr), Cairo (5000/yr) and Delhi (3500/yr) rank highest with cardiovascular mortality. The morbidity (hospital admissions) due to degenerative Obstructive Pulmonary Disease (COPD) follows the tendency of cardiovascular mortality. Dhaka and Karachi lead the rankings, having about 2100/yr excess cases, while Osaka-Kobe (20/yr) and Sao Paulo (50/yr) are at the low end of all megacities considered.

Since air pollution is increasing in many megacities, and our database of measured pollutants is limited to the menses up to 2000 and does not include all relevant components (e.g. O3), these numbers should be interpreted as lower limits. South Asian megacities most urgently need improvement of air pure tone to prevent excess mortality and morbidity due to exceptionally high levels of air pollution. The risk estimates obtained from Ri-MAP present a vivid baseline evaluation for the consequences of ambient air pollution in comparison to simple air quality indices, and can be expanded and improved in parallel with the development of air pollution monitoring networks.
