摘要：A consensus has been emerging among public health experts in developing countries that air pollution,even at current ambient levels, aggravates respiratory and cardiovascular diseases and leads to premature mortality.Recent studies have also presented well-founded theories concerning the biological mechanisms involved and thegroups of people that are probably more susceptible to health effects caused or exacerbated by inhalation of ambientparticulate matter (PM.). Air quality in Hyderabad, India, often exceeds the national ambient air quality standards,especially for particulate matter (PM), which, in 2010, averaged 82.2 ± 24.6, 96.2 ± 12.1, and 64.3 ± 21.2 μg/m3 ofPM10, at commercial, industrial, and residential monitoring stations, respectively, exceeding the national ambientstandard of 60 μg/m3. A study was conducted to quantify source contributions to PM pollution in Hyderabad, using thechemical mass balance receptor model for 180 ambient samples collected at five stations for PM10 and PM2.5 sizefractions. The receptor modelling results indicated that the PM10 pollution is dominated by the direct vehicular exhaustand road dust (fugitive dust) (more than 60 %). PM2.5 with higher propensity to enter the human respiratory tracks hasmixed sources of vehicle exhaust, industrial coal combustion, garbage burning, and secondary PM. In order to improvethe air quality in the city, these findings demonstrate the need to control emissions from all known sources andparticularly focus on the low-hanging fruits like road dust and waste burning, while the technological and institutionaladvancements in the transport and industrial sectors are bound to enhance efficiencies.
