Rapid and unplanned industrialization and urbanization has resulted in the deterioration of India's air quality according to air-quality monitoring carried out in seven major Indian cities in industrial and residential areas between 1995 and 2000. Suspended particulate matter (SPM) levels in Indian cities are in the range 50 to 550 microg/m(3). NO(x) values are high in Delhi's residential areas, with values of 33 microg/m(3) in 1995 and 34.6 microg/m(3) in 2000, while in an industrial area values of 29.4 microg/m(3) were found in 1995, increasing to 33.7 microg/m(3) in 2000. SO(2) values are very high in Pune city, ranging from 43.3 microg/m(3) in residential to 43.69 microg/m(3) in an industrial area in 2000.
根据1995年至2000年间在印度七个主要城市的工业区和居民区进行的空气质量监测，快速且无规划的工业化和城市化导致了印度空气质量的恶化。印度城市中的悬浮颗粒物（SPM）水平在50至550微克/立方米之间。德里居民区的氮氧化物（NO(x)）值较高，1995年为33微克/立方米，2000年为34.6微克/立方米，而在一个工业区，1995年的值为29.4微克/立方米，2000年增至33.7微克/立方米。浦那市的二氧化硫（SO(2)）值非常高，2000年在居民区为43.3微克/立方米，在工业区为43.69微克/立方米。
