Sources of marine pollutants

Direct discharge

Pollutants enter rivers and the sea directly from urban sewerage and industrial waste discharges, sometimes in the form of hazardous and toxic wastes.

Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor.

Ship pollution

Ships can pollute waterways and oceans in many ways. Oil spills can have devastating effects.

Discharge of cargo residues from bulk carriers can pollute ports, waterways and oceans.

Plastic debris Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Discarded plastic bags, six pack rings and other forms of plastic waste which finish up in the ocean present dangers to wildlife and fisheries. 

Oil spill An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution.

Contact with crude oil or refined fuel oils. This causes feathers to collapse and matt and change the insulation properties of feathers and down.

The food searching instincts such as diving and swimming are inhibited.

Severe irritation of the skin.reduced reproduction ability

Effect of marine pollution

Two main methodsCorrection – costly and time intensivePrevention – requires attitude changes

Coastal Scientists believe that prevention is better

than cure since the effects of marine pollution may

be irreversible and we may therefore be creating

everlasting damage to the marine ecosystem.
