air pollution Current Affairs - 2020
On June 8, 2020, the Ministry of Road Transport and Highways issued distinct colour band for the number plate sticker of BS VI vehicles.
The order makes it mandatory for the BS VI vehicles to carry a green strip of 1 cm width on the top of the existing sticker. The sticker should carry details of registration of BS-VI vehicle and its fuel type. The petrol fuel vehicles should hold orange colour and diesel fuel vehicles should carry a blue colour.
BS VI Emission Norms
The volume of PM 2.5 in BS VI fuel ranges between 20 and 40 micro grams per cubic metres. On the other hand, it is 120 micrograms per cubic metres in BS IV fuel. The BS VI fuel is to bring down the Sulphur content by 5 times. The BS VI fuel vehicles will emit 80% less particulate matter for every kilo metre.
The lower Sulphur of BS VI will help reduce toxic emissions such as CO, nitrogen Dioxide and Sulphur Dioxide. The change in density of oil will help reduce air pollution to great extent.

A woman innovator from Kerala, Vasini Bai has developed 10 varieties of Anthurium flower. The flower has high market value for its major usage as an indoor decorative. As the innovator was unable to meet high demand of highly time-consuming technique, the National Innovation Foundation has stepped in.
The National Innovation foundation has facilitated mass multiplication and large- scale production of four of the high demand varieties. This is to be done at the Indian Institute of Horticultural Research, Bangalore. The institute is to adopt cross tissue culture technique to develop the flowers.
The Anthurium flowers have gained their significance lately for their purification qualities. They purify the surrounding air. Also, they remove harmful airborne chemicals such as ammonia, formaldehyde, toluene, allergens and xylene.
NASA has placed the plant under the list of air purifier plant.
National Innovation Foundation
The National Innovation Foundation operates under Department of Science and Technology. It was set up in February 2000 to provide support to the grass roots innovations in the country. The most popular IGNITE annual competition is organized by National Innovation Foundation.
