Delhi lacks long-term plan to check industrial pollution
Source: Hindustan Times, Date: , 2016
Industries and power plants in and around Delhi are the biggest source of pollutants, SO2 and NOx, that cause breathing ailments in the city. A study by the Indian Institute of Technology (IIT) Kanpur revealed that power plants, industrial clusters, restaurants and the diesel generators are the primary source of pollution from sulfur dioxide (SO2) and nitrogen oxides (NOx). Nine months have passed since the findings but nothing has been done to implement the recommendations to control pollution from industrial sources. As per the study, almost 98% of the 142 tonne SO2 and 60 per cent of the 312 tonne NOx emitted in Delhi’s air every day, comes from these sources. Breathing SO or NOx for short periods can cause adverse respiratory effects such as airway inflammation, bronchoconstriction and asthma symptoms. The pollutants also harm health by reacting in the atmosphere to form sulphate or nitrate fine particles, PM2.5, that chock airways to lungs.
