This paper mainly deals with the measurement of air quality by observing the concentration of pollutants in the atmosphere namely suspended particulate matter, NOx and SO2 at five different selected locations in Lucknow city. The locations for the study have been chosen on the basis of land use pattern. Each pollutant has been observed by 12 hours from 8:00 to 20:00 hours. According to air quality scale, the air quality status has been measured at each location and zone. From the study it is found that the residential zone has highest air quality index in comparison to other zones.

Three key polutants, namely RSPM, SO2 and NO2 have been measured in schools in the National Capital Region (Delhi). Monitoring was conducted at all the 5 locations. Alarming levels of pollutants were reached on Diwali day, a festival of lights and for days preceding Diwali at all the locations.

Long- and short-term exposures to air pollution, especially fine particulate matter (PM2.5), have been linked to cardiovascular morbidity and mortality. One hypothesized mechanism for these associations involves microvascular effects. Retinal photography provides a novel, in vivo approach to examine the association of air pollution with changes in the human microvasculature.
 

PM10 and PM2.5 samples were collected from a kerbside at a traffic junction in a major metropolis of India during month of December 2005 and their concentrations were calculated. The Pm2.5 fraction in PM10 varied from 18.7 to 72.6%. Such a large variation was correlated with meteorological variables.

This paper analyzes the sectoral energy consumption pattern and emissions of CO₂ and local air pollutants in the Kathmandu Valley, Nepal. It also discusses the evolution of energy service demands, structure of energy supply system and emissions from various sectors under the base case scenario during 2005–2050.

Ground-level concentrations of ozone (O3) and fine particulate matter [? 2.5 µm in aerodynamic diameter (PM2.5)] have increased since preindustrial times in urban and rural regions and are associated with cardiovascular and respiratory mortality.

The Yangtze River Delta (YRD) is the fastest growing economic development region in China and one of the most densely populated regions in the world, with recent dramatic increases in energy consumption and atmospheric emissions. To inform air pollution control strategy design, Zhou et al. studied how different emission sectors influence population exposures and corresponding health risks.
