Incorrect Answer1, 2, 3 and 4
Correct AnswerExplanation:
Air pollutants emitted from biomass open burning whether forest fires or crop residues, include common greenhouse gases (GHGs) such as carbon dioxide (CO2), carbon monoxide (CO), methane (CH4) and nitrous oxide (N2O) as well as volatile organic compounds (VOCs), ammonia (NH3), sulphur dioxide (SO2), nitrogen oxides.
Satellite observations have revealed elevated levels of O3 (Ozone), CO and aerosols over vast areas of Central Africa and South America, over the tropical Atlantic, and the Indian Ocean due to long-range transport of pollutants emitted from biomass burning.
