Understanding Sulphur Emissions
Sulphur emissions are primarily produced from both natural and anthropogenic (human-made) sources. Identifying these sources is crucial for environmental studies and policy-making.
Natural Sources of Sulphur Emissions
Natural sources of sulphur emissions include:
- Seas and Oceans: The oceans release dimethyl sulfide (DMS), a natural compound that contributes to atmospheric sulphur. Marine phytoplankton produce this compound, which plays a role in cloud formation and climate regulation.
- Volcanic Eruptions: Volcanoes emit significant amounts of sulphur dioxide (SO2) during eruptions. This gas can lead to acid rain and has implications for air quality and climate.
- Biological Processes in Soil: Microbial activity in soil, particularly in wetlands, produces sulphur compounds. These processes are essential for nutrient cycling in ecosystems.
Human-Made Sources of Sulphur Emissions
- Burning of Coal: This is a major anthropogenic source of sulphur emissions. When coal is burned for electricity or heat, it releases large quantities of sulphur dioxide (SO2) into the atmosphere, contributing significantly to air pollution and acid rain.
Conclusion: Why 'C' is the Correct Answer
The correct answer to the question is option 'C' (Burning of coal) because it is primarily a human-made source of sulphur emissions, unlike the other options listed. The natural sources (seas, volcanic eruptions, and biological processes) occur without human intervention, while burning coal directly results from human activities.
