Frequently asked questions :

Q: What are the main sources of sulphur dioxide?
A: The main sources of sulphur dioxide include burning fossil fuels, such as coal and oil, in power plants, industrial processes like smelting and refining of metals, and volcanic activities. It is also emitted from vehicles and some chemical manufacturing processes.

Q: What are the common uses of sulphur dioxide?
A: Sulphur dioxide has several industrial applications. It is used as a preservative in the food and beverage industry to prevent spoilage and bacterial growth. It is also utilized as a reducing agent in chemical processes, a bleaching agent in paper production, and a refrigerant in some cooling systems.

Q: Is sulphur dioxide harmful to human health?
A: Yes, sulphur dioxide can be harmful to human health, particularly when present in high concentrations. It can irritate the respiratory system, leading to coughing, wheezing, shortness of breath, and throat irritation. Individuals with pre-existing respiratory conditions, such as asthma, may be more sensitive to its effects.

Q: What are the environmental impacts of sulphur dioxide?
