An oil spill is the accidental or deliberate release of petroleum products, such as crude oil, diesel or fuel oil, into oceans, seas, rivers or coastal environments, resulting in water pollution and ecological damage.
- Accidents involving oil tankers and cargo ships.
- Leakage from offshore oil drilling platforms.
- Damage to underwater oil pipelines.
- Illegal discharge of oily waste from ships.
- Natural disasters affecting oil storage and transportation facilities.
Ecological Impact of Oil Spill
- Marine Biodiversity: Toxic hydrocarbons can kill fish, plankton, shellfish and other marine organisms.
- Birds and Mammals: Oil coats feathers and fur, reducing insulation and buoyancy, potentially causing hypothermia and death.
- Coral Reefs: Toxic substances damage coral tissues, affecting growth and reproduction.
- Mangroves: Oil blocks root structures and interferes with gas exchange, leading to mangrove degradation.
- Food Chain: Toxic hydrocarbons can enter marine food webs and accumulate in organisms.
- Photosynthesis: Surface oil slicks reduce light penetration, affecting phytoplankton and aquatic plants.
- Reproduction: Oil exposure can impair the growth, reproduction and survival of marine species.
- Long-term Impact: Persistent oil residues contaminate coastal sediments, beaches and sensitive habitats.
Who Looks After Oil Spill Control in India?
- The Indian Coast Guard, under the Ministry of Defence, is the central coordinating authority for oil spill response in India’s maritime zones. It was assigned this responsibility in 1986.
