- Oil Pollution
- Causes
- Vehicle engine lubricating oil leaking or being discarded
- Industrial machine oil washed into drains or mixed with other effluents
- Washing ship oil tankers and disposing the dirty water at sea
- Tanker accidents
- Discharged bilage (waste) water or lubrication oil released due to accidents
- Accidental spillages from oil refineries, storage or pipelines
- Leakages during the exploration, extraction and drilling from oil platforms
- Effects
- Reduces dissolution of oxygen at water surface
- Smothers and asphyxiates molluscs
- Can be toxic
- Bird feathers lose their water proofing and thermal insulation = hypothermia
- Ingested oil prevents digestion = starvation
- Birds unable to locate mates by smell = reduced breeding success
