Stubble burning: Burning of stubble (material remaining in the field after harvesting) in rural areas leads to air pollution in both rural and urban areas. Indoor air pollution: Due to the use of non-traditional fuel resources such as wood, cow dung, etc. the women in rural areas are exposed to indoor air pollution in form of CO2, CO, etc.
