Weld County, a 4,000-square-mile area northeast of Denver, this year received failing air quality grades for ozone and particulate matter — pollutants linked to fossil fuel extraction — from the American Lung Association. The Colorado Springs area received failing grades for ozone in 2024.
Chlorine, Ozone, Sodium hypochlorite, Chlorine Di-Oxide , even non-chemical methods of disintegrating the pathogens like UV and IR also used many times, especially for water purification. To resolve this for disinfection of surfaces and contact points like handles etc. It is recommended to use oxidisers as disinfectants. 2003; Loret et al.
But there are other GHGs that contribute significantly to human-induced global warming such as methane (CH 4 ), nitrous oxide (N 2 0), refrigerant gasses (HFCs, PFCs, and CFCs), sulfur hexafluoride (SF 6 ), water vapor (H 2 0), and ozone (O 3 ). What’s the relevance of these different GHGs to carbon footprinting? .
