Coal Dust
Context
A recent study in Jharsuguda, Odisha, has highlighted the harmful effects of coal mining dust on local vegetation. The research, using satellite data, shows how dust from open-cast coal mining harms plant growth and carbon absorption.
What is Coal Dust?
- Coal dust is a fine particulate matter produced during mining activities, such as blasting rocks, drilling, and transporting coal. It settles on nearby vegetation, affecting their ability to function.
- Impact of Coal Dust on Vegetation:
- Reduced Carbon Absorption: Dust blocks the pores (stomata) on plant leaves, preventing effective absorption of carbon dioxide, which impacts photosynthesis.
- Plants with 1 gram of dust absorb 2-3 grams less carbon per square meter of area.
- Temperature Regulation Disruption: Dust prevents plants from releasing water vapor, causing them to overheat and impair photosynthesis, leading to stunted growth or plant death.
- Reduced Carbon Absorption: Dust blocks the pores (stomata) on plant leaves, preventing effective absorption of carbon dioxide, which impacts photosynthesis.
