Giving out measures to check the emissions by DG sets in Delhi/NCR at Amity University, Dr. Sengupta opined that power availability in Delhi/NCR has to be improved by providing grid supply, new commercial DG sets in Noida and Delhi should be based on CNG and existing DG sets should be retrofitted with requisite pollution control system to reduce Nitrogen Oxides and soot particles.

Dr. Sengupta remarked that most critical and harmful pollutant in the air is PM2.5 and the major contributors of PM2.5 in the environment are combustion sources like vehicles, coal, biomass, garbage combustion.

Expressing his concern, he said “The levels of Benzene and PM2.5 are very high in the air of Noida which is a matter of grave concern since an average adult inhales 12,000- 15,0000 litres of air everyday and PM2.5 easily enters into respiratory track and blood. Continuous and excessive inhaling of PM2.5 could cause dire problems such as premature deaths, lung cancer, heart attacks and development of chronic lung diseases and other problems”
