Particulates Current Affairs, GK & News
Debayan Saha, a mechanical engineering graduate from IIT Kharagpur, has invented a device called “PM 2.5” which he claimed when fitted near the silencer pipe in vehicles will curb air pollution. The technology developed by him uses a combination of electric energy and wave energy to influence the pollutants like PM 2.5 such that they ..
Ministry of Environment, Forest and Climate Change has established a committee to implement the National Clean Air Program. The motive behind this is to decrease the PM (particulate matter) 2.5 and PM 10 concentration by 20% to 30% in at least 102 cities by 2024. The committee will be headed by the Secretary, Union Environment ..
