Fats, Oil, Grease (FOG) Affecting Marine Life

The harmful fats, oil, grease (FOG)

Chemical constituents from Fats, Oil, Grease (FOG) are poisonous. It can harm marine life through ingestion, inhalation, absorption or external exposure through skin and eyes irritation.


Most affected animals

Oil will float on water, which makes mammals like sea otters and seabirds the most affected animals.  Oil damage the insulating ability and the water repellent level of a bird’s feather thus expose them to harsh chemical. They will have difficulty trying to stay warm hence they can die of hypothermia. Oiled bird can lose the ability to fly or dive for food. When birds groom themselves, they can accidentally ingest the oil on their body. It can be dangerous to their organs.


What about fishes?

We are not saying that fishes will not be harmed. Most often, fin-fish and shellfish are only briefly harmed because most oils remain at top level and hardly expose to organism living on the ocean floor or in the water column. However, these animals can be substantially harmed in some circumstances, especially when oils goes into shallow or confined waters. Oil also greatly affects the reproduction of fishes such as eggs and larval survival.
