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 ..

Now, in India, air pollution is the third-highest cause of death among all health risks, ranking just above smoking. ..
On January 10, Union Environment Minister Dr. Harsh Vardhan launched the much-awaited National Clean Air Programme (NCAP) to combat air pollution. The NCAP is a pollution control initiative that was launched with the intention to cut the concentration of coarse (PM10) and fine particles (PM2.5) by at least 20% in the next five years, with ..
Aerosols are tiny particles formed both naturally and anthropogenically; naturally formed aerosols are dust whipped by wind, sea salt, sulphate compounds arise by natural processes and plants release organic materials into the air and aerosols formed by anthropogenic activities are soot, sulphates from the burning of fossil fuel, fly ash from thermal plants & nitrates ..

Black Carbon is formed as a by-product of incomplete combustion of fossil fuels, bio-fuels and biomass. It is the strongest absorbent of light amongst all the components of particulate matter. Main Properties of Black Carbon It is directly emitted in the atmosphere as fine particles PM5. It is highly effective in absorbing solar energy and ..
