NO2/ PM10 study published from Dehli and Kanpur, India

A fast growing population coupled with industrialization, urbanization and high levels of energy consumptions is worsening the air quality particularly in developing countries. NO₂ is regulated in most of the countries and is used as an indicator to assess the status of ambient air quality in the urban environments such as Dehli, India.

Passive sampling with NO₂ samplers was conducted at 204 and 101 sampling locations in Delhi and Kanpur, respectively. It was observed that Delhi and Kanpur experienced an average NO₂ concentration of 68.6 ± 20.1 lg/m3 and 36.9 ± 12.1 lg/m3, respectively. A significant correlation between NO2 and PM10 in both cities suggests that the spatial pollution mapping of NO₂ is good enough to describe the patterns and trends that are also valid for other pollutants. On the basis of survey results on  missionactivities, meteorology and guidelines for site selection criteria with its characteristics (urban, traffic and suburban types), this study proposes that Delhi and Kanpur need fifteen and eight number of sampling sites to represent the complete pollution scenario
