Air Quality Study 1

This report presents the findings of a detailed survey of air pollution indices that are presently utilized or available. The survey included a review of the existing literature on air pollution indices, telephone discussions with personnel from the 55 largest air pollution control agencies in the United States...

While air pollution poses a humungous challenge to most bustling cities across India now, it raised concerns way back in the 1960's as well. Owing to industrial development, in India, cities such as Bombay, Delhi, Kanpur, Calcutta and new industrial townships such as Durgapur, Neyvelli and Rourkela had begun to manifest symptoms of air pollution like suffocation, increasing fog and invisibility.

Coincidentally, the establishment of the Central Public Health Engineering Research Institute (CPHERI) in 1958, (as CSIR-NEERI was known then), helped the industries and civic bodies that were grappling with pollution related issues, to a larger extent.

One of the objectives of this institute was to help Indian industries solve their occupational health and industrial hygiene problems.

In the 60's, an air pollution survey was taken of Nagpur and its environs --- Even though at that time Nagpur was not a highly industrialised city and was comparatively free from air pollution, except for certain areas, it was useful to train personnel in the methodology of air pollution assessment techniques. Moreover, it served as a yardstick to judge the exent of air pollution in highly industrialised cities such as Delhi, Bombay and Calcutta, and would come in handy at a later stage, when the pollution levels in these metros would be tested.

In order to study the efficiency of fabricated air sampling, a sample dilution chamber was designed, and it worked successfully. The design and fabrication of useful kinds of instruments was also taken up. It was found that the design and fabrication of a portable sampling kit was extremely useful for studying the levels of gaseous elements in the enviroment. Read More »

Promoting science as a tool for air pollution mitigation and making its understanding easy for the larger audience.

lndAIR would act as a platform for air quality research in India across domains and help in providing a better understanding of the issue.

History of Air Pollution in India

Air pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into the Earth's atmosphere. Air pollution in India is a serious issue, ranking higher than smoking, high blood pressure, child and maternal malnutrition, and risk factors for diabetes. At least 140 million people breathe air 10 times or more over the WHO safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in India. Air pollution contributes to the premature deaths of 2 million Indians every year.
