Sulphur dioxide is a colorless gas with a pungent odor that is produced from burning coal and oil, as well as certain industrial processes like metal extraction. It is also found naturally in volcanic eruptions and some biological processes.

Health Effects

Sulphur dioxide can have negative effects on human health when inhaled, particularly for individuals with asthma or other respiratory conditions. Short-term exposure can lead to throat and eye irritation, coughing, and shortness of breath, while long-term exposure can cause respiratory illnesses and exacerbate existing conditions.

Environmental Impact

When sulphur dioxide is released into the atmosphere, it can react with other compounds to form acid rain, which can harm plants, animals, bodies of water, and buildings. Acid rain can also contribute to soil acidification, impacting plant growth and water quality.

Regulation and Control

Due to its harmful effects on both human health and the environment, sulphur dioxide emissions are regulated by many governments around the world. Strategies for control include using cleaner fuels, improving industrial processes, and implementing scrubbers in factories to remove sulphur dioxide from emissions.

Sulphur dioxide is a significant air pollutant that requires careful monitoring and control to protect human health and the environment. By reducing emissions, we can mitigate the negative impacts of this compound and work towards a cleaner, healthier future for all.
