IndAIR: CSIR-NEERI’s web facility launched

The Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI) has launched the country’s first interactive online repository, called IndAIR or Indian Air quality Interactive Repository. The repository is one of few such facilities in the world and has the maximum number of studies-262 concerning Delhi-NCR.

About IndAIR

Objective: The project aims to make air quality research and studies in an easily accessible web format for the public, media, researchers and academics.

NEERI has been working to develop a web repository of all research that has been done on subjects in India. The endeavour will be first comprehensive effort to inventorise surviving Indian research and analysis on air pollution, its causes and effects.

It has archived about 700 scanned materials from pre-internet era, 170 reports and case studies, 1,215 research articles, 100 cases and more than 2,000 statutes to provide the history of air pollution research and legislation in India.

IndAIR began to document important milestones in India to make them available to public, help academicians and also enable policy-makers to frame legislations. The web facility would also be a useful platform for scientific community to share its current work and exchange ideas.

The website reveals air pollution was recognised as a subject in India even in 1905, when a study was carried out for Bengal Smoking Nuisance Ac and showcases how discussions on the ills of air pollution began wholeheartedly in 1970s, while studies were undertaken as early as 1950s.

WAYU: Air pollution control device inaugurated in New Delhi

Union Minister for Science & Technology and Earth Sciences and Environment Dr. Harsh Vardhan inaugurated air pollution control device WAYU (Wind Augmentation PurifYing Unit) for traffic junctions at ITO intersection and Mukarba Chowk in New Delhi. The device aims at tackling toxicity in air by sucking in particulate matter and release fresh air

WAYU (Wind Augmentation PurifYing Unit)

It has been indigenously developed by Council of Scientific and Industrial Research – National Environmental Engineering Research Institute (CSIR-NEERI) as part of Technology Development Project being funded by Department of Science and Technology. Its prototype has capacity to purify air in area of 500 meter square. It consumes only half unit of electricity for 10 hours of running and has maintenance cost of only Rs. 1500 per month.

Working: The device works on two principles mainly wind generation for dilution of air pollutants and active pollutants removal. It has filters for particulate matter (PM) removal and activated carbon (charcoal) and UV lamps for poisonous gases removal such as Volatile organic compounds (VOCs) and Carbon Monoxide. It has one fan and filter for sucking and removing PM. It also has two UV lamps and half kg of activated carbon charcoal coated with special chemical Titanium Dioxide.

Bigger version: CSIR-NEERI is in the process of developing bigger version of WAYU which can purify air in area of 10,000 meter square. It will also make designs of future WAYU devices better in aesthetics and can be deployed in bus shelters etc.
