TAILIEUCHUNG - The Health Effects of Air Pollution in Delhi, India

Direct users of the information Apheis produces and disseminates include the scientists who appear just to the right of the Apheis box and who receive information directly from Apheis. These scientists in turn pass that information on to other scientists and to committees, seen in the box further to the right, all of whom thus become pass-on users, because they receive the information Apheis produces indirectly from Apheis. Then, the individual scientists and committees pass Apheis information on to the policy advisors below them, who form another group of pass-on users. And those policy advisors in turn pass the information on to policy makers, who review. | Policy Research Working Paper WPS l foo 1860 The Health Effects of Particulate air pollution has . less overall impact on Air Pollution in Delhi India nontraumatic deaths in Delhi India than in . cities.

Sharma The World Bank Development Research Group December 1997 Policy Research Working Paper 1860 Summary findings Cropper Simon Alberini and Shar na report the results of a time-series study of the impact of particulate air pollution on daily mortality in Delhi. They find A positive significant relationship between particulate pollution and daily nontraumatic deaths as well as deaths from certain causes respiratory and cardiovascular problems and for certain age groups. In general these impacts are smaller than those estimated for other countries where on average a 100-microgram increase in total suspended particulates TSP leads to a 6-percent increase in nontraumatic mortality. In Delhi such an increase in TSP is associated with a increase in deaths. The differences in magnitudes of the effects are most likely explained by differences in distributions of age at death and cause of death as most deaths in Delhi occur before the age of 65 and are not attributed to causes with a strong association with air pollution. Although air pollution seems to have less impact on mortality counts in Delhi the number of life-years saved per death avoided is greater in Delhi than in . cities because the age distribution of impacts in these two places varies. In the United States particulates have the greatest influence on daily deaths among persons 65 and older. In Delhi they have the greatest impact in the 15-to-44 age group. That means that for each death associated with air pollution on average more life-years would be saved in Delhi than in the United States. Large differences in the magnitude of effects do .
