Sulphur dioxide causes irritation of eyes and respiratory diseasesIntroduction
Air pollution is one of the major environmental issues that need to be addressed as it has a significant impact on human health. Air pollutants can cause a wide range of health problems, from minor irritations to serious respiratory diseases. One such pollutant is sulphur dioxide.
Sulphur dioxide
Sulphur dioxide (SO2) is a colourless gas with a pungent odour. It is created by the burning of fossil fuels that contain sulphur, such as coal and oil. It is also produced by industrial processes such as smelting, refining, and the production of paper, pulp, and chemicals.
Health effects of sulphur dioxide
Exposure to sulphur dioxide can cause a range of health problems, including:
- irritation of the eyes, nose, and throat
- coughing and wheezing
- shortness of breath
- asthma attacks
- bronchitis
- emphysema
- respiratory infections
- cardiovascular disease
How does sulphur dioxide cause health problems?
When sulphur dioxide is inhaled, it reacts with water and other chemicals in the air to form sulphuric acid and other harmful compounds. These compounds can irritate the eyes, nose, and throat, causing symptoms such as coughing and wheezing. They can also cause inflammation of the airways and lungs, making it difficult to breathe. Long-term exposure to sulphur dioxide can lead to chronic respiratory diseases such as emphysema and bronchitis.
Conclusion
Sulphur dioxide is a harmful air pollutant that can cause a range of health problems. To reduce exposure to sulphur dioxide, it is important to take steps to reduce emissions from industrial processes and to use cleaner fuels. Regular monitoring of air quality is also essential to ensure that levels of sulphur dioxide and other pollutants remain within safe limits.
