In this and other provinces, farmers burn the canes as a means of easing the harvesting process.
Smog generated from the practice have caused respiratory problems among some of the residents nearby, requiring treatment in hospitals.
Hazardous air pollutants from cane burning include carbon monoxide, volatile organic compounds, small particles and dust, according to the Office of the Cane and Sugar Board.
These toxic emissions could cause irritation to people’s noses and throats, affecting their breathing if exposed to the air pollution for a long time.
Moreover, carbon monoxide can slow down the flow of blood while organic compounds with carbon component, such as Toluene, Methylene Chloride and Methyl Chloroform, are harmful to humans and plants.
Cane burning creates heat and rapid air pollution with the spread of dust and small particles, hovering 2,250 metres overhead, up to 16 kilometres from the fire.
Another cause of air pollution was the illegal burning of forest trees, according to the report.
Despite social media posting on the cane-burning issue, none of the victims have revealed their identities, making it difficult for relevant agencies to take actions.
