What are the potential hazards of Sulphur Dioxide (SO2)?

Sulphur Dioxide (SO2) is a colourless gas with a pungent odor, produced primarily by the combustion of sulphur-containing fuels in industrial processes and transportation. It is a common air pollutant and poses significant hazards to both human health and the environment.

Key gas hazards associated with Sulphur Dioxide (SO2) include:

Inhalation of SO2 can irritate the respiratory system, leading to symptoms such as coughing, wheezing, shortness of breath, and chest tightness. Individuals with pre-existing respiratory conditions such as asthma or chronic bronchitis are particularly susceptible to SO2-induced exacerbations.

SO2 emissions contribute to air pollution and can react with other compounds to form particulate matter and acid rain, which can harm ecosystems, damage vegetation, and degrade air quality. Acid rain can also corrode buildings, infrastructure, and cultural heritage sites.

Workers in industries such as power generation, metal smelting, and chemical manufacturing may be exposed to elevated levels of SO2, requiring appropriate respiratory protection and ventilation measures.
