Q35. Consider the following:
- Carbon monoxide
- Methane
- Ozone
- Sulfur dioxide
Which of the above are released into the atmosphere due to the burning of crop/biomass residue?
(a) 1 and 2 only
(b) 2, 3 and 4 only
(c) 1 and 4 only
(d) 1, 2, 3 and 4
Answer: D
- Burning of crop or biomass residue means burning of living or dead vegetation including grassland, forest, and agricultural waste for fuel. Recent crop harvesting practices use mechanical harvesters in the rice and wheat farm system in India which leaves behind large quantities of crop residue in the field. However, there is no suitable method available for managing the crop residues. Burning of crop residues emits traces of
- carbon dioxide, methane, carbon monoxide, nitrous oxide, sulfur dioxide and particulates which affect human health. Punjab and Haryana are both responsible for causing air pollution due to burning. These two states contribute to 48 per cent of the total emission due to paddy burning across India.
