Question

Consider the following:Carbon monoxideMethaneOzoneSulphur dioxideWhich of the above are released into atmosphere due to the burning of crop/biomass residue?

Accepted Answer

Crop residues / biomass burning are cheap and easiest method to dispose the leftover crop residues (wheat, rice, sugarcane etc.) after harvesting, for land clearing and pest control. Burning of crop residues is a common approach to eliminate waste after harvesting all over the world. Burning of these residues emit gases like sulphur dioxide (SO2), oxides of nitrogen (NOx), carbon dioxide (CO2), carbon monoxide (CO), black carbon (BC), organic carbon (OC), methane (CH4), volatile organic compounds (VOC), non-methane hydrocarbons (NMHCs), ozone (O3), and aerosols etc which affect the global atmospheric chemistry and climate.
