Time Running out to Curb Effects of Deep Sea Pollution, Warns UN
Time Running out to Curb Effects of Deep Sea Pollution, Warns UN Published on Saturday, June 17, 2006 by the Guardian / UK .
Damage to the once pristine habitats of the deep oceans by pollution, litter and overfishing is running out of control, the United Nations warned yesterday.
In a report that indicates that time is running out to save them, the UN said humankind's exploitation of the the deep seas and oceans was 'rapidly passing the point of no return'.
Last year some 85 million tonnes of wild fish were pulled from the global oceans, 100 million sharks and related species were butchered for their fins, some 250, 000 turtles became tangled in fishing gear, and 300, 000 seabirds, including 100, 000 albatrosses, were killed by illegal longline fishing.
Into the water in their place went three billion individual pieces of litter - about eight million a day - joining the 46, 000 pieces of discarded plastic that currently float on every square mile of ocean and kill another million seabirds each year.
Achim Steiner, executive director of the UN's environment programme, said: 'Humankind's ability to exploit the deep oceans and high seas has accelerated rapidly over recent years.

Terma - Radar Surveillance
Radar Surveillance Airborne Surveillance Systems Against Sea Pollution For more than 15 years, Air Atlantique has been using the Terma surveillance systems to combat oil pollution at sea.
The most recent system was delivered in 2002.For more than 15 years, Air Atlantique has been fighting the oil pollution at sea.
Air Atlantique has detected oil pollution, traced polluters and assisted in clean-up operations in numerous countries around the world.The Terma Surveillance System may be installed in small twin engine, as well as larger aircraft.
The main sensor is the Side Looking Airborne Radar (SLAR) which is able to detect oil pollution at a distance of more than 20 Nautical Miles on each side of the aircraft.

Sea Pollution And Health
Many waste substances that have been disposed of into the sea can cause a variety of acute and chronic health conditions.
There are two major ways in which humans can be contaminated by these pollutions.
The first is direct contact either through the skin, lungs or by being digested; swimming in polluted sea water would be a good way of being contaminated by a direct contact method.
Direct contamination is a less significant way in which humans can be exposed to toxic organic chemical and metals because they tend to be in sea water in low concentration.
In the case of pathogens both methods can be significant because only small numbers of micro organisms to induce disease and because micro organisms can reproduce in infected animals and the environment..
There are three main categories of pollutants in the sea that can reach and have adverse affects on human health.
Toxic metals that have been disposed of in the sea have impacts concerning human health, especially arsenic, cadmium, lead and mercury.
These four metals are particularly of concern because they are known to be toxic to human health and have been found in high concentration in river estuaries and the sea.
