India, Feb. 25 -- Ultrafine particles having almost negligible weight, surface area do have an effect on haze formation, visibility and air pollution, the studies found

The smallest, invisible particles matter the most when it comes to dealing with air pollution, researchers have found in two recent studies.

Ultrafine particles - which have almost negligible weight and surface area and are hence are not considered a threat to the air we breathe - do have an effect on haze formation, visibility and air pollution.

These were the takeaways the studies published in journals Faraday Discussion and Nature NPJ climate and atmospheric science .

The scientists looked into the phenomenon called atmospheric new particle formation (NPF) and growt...
