The ever increasing Particulate Matter (PM) levels around the world including India, especially in Delhi,  have raised serious concerns. Particulate matter  are fine particles, which remain suspended in the air for a long time and enter our lungs through  inhalation. The fine particles of size < 2.5 µ are declared as health hazard as they penetrate deep into lungs and lodge  themselves there. Ineffective clearance of this PM from the airways could cause particle retention in lung tissues, resulting in a chronic, low-grade inflammatory response that may be patho-genetically important in both the exacerbation, as well as, the progression of lung disease.

 

It becomes therefore important to find a solution to this threat. In our recent research experiments conductssionsed indoors in Delhi and NCR it was seen that the Particulate Matter, though increased slightly on the day of Yagya, finally reduced by 74% and 71% on the next day and day after. Chemical analysis of the gaseous emissions of yagya show that the combustion of fatty substances produces  number of hydrocarbons and other chemicals in small quantities like acetone bodies, pyruvic aldehyde, glycol, glyoxal etc, most of which are anti-bacterial and thus purifies the air and kills the harmful pathogens which are detrimental to human health.
