Not in NEET syllabus
Under column I, a list of gases known to have a 'green-house effect' is given. Relate them to their main source, selecting from the list under column II.
Column I: A. Nitrous oxide () B. Chlorofluorocarbons (CFCs) C. Methane () D. Ozone () E. Carbon dioxide () Column II: (1) Secondary pollutant from car exhausts (2) Combustion of fossil fuels, wood, etc. (3) Denitrification (4) Refrigerators, aerosol sprays (5) Cattle, rice fields, toilets
Solution
Nitrous oxide is mainly produced through microbial denitrification in soils (A-3); CFCs are released from refrigerants and aerosol sprays (B-4); methane is mainly generated from cattle (enteric fermentation), rice paddies and sewage/toilets (C-5);
