The study found that chloride-rich particles were the highest inorganic fraction in particulate matter.

Chloride-rich particles resulting from plastic burning may be primarily responsible for haze and fog formation in Northern India, including Delhi, during the winter months, according to an international study led by researchers from the Indian Institute of Technology (IIT) Madras.

The study, published in the journal Nature Geoscience, may help develop better policies to improve the air quality and visibility in North India.

Many studies in the past have identified particulate matter or aerosol particles with diameter less than 2.5 micrometre (PM2.5) as a major pollutant, responsible for haze and fog formation over Indo-Gangetic plain, including Delhi.

However, the role of PM2.5 and detailed chemistry of haze and fog formation over national capital was poorly understood.

The new study found that chloride-rich particles were the highest inorganic fraction in particulate matter, primarily responsible for haze and fog formation in the region.
