Lack of Oxygen
 This Fine Piece of Water: An Environmental History of Long Island Sound by Tom Andersen, Long Island Sound is not only the most heavily used estuary in North America, it is also one of the most beautiful waterways, with picturesque seascapes and landfalls. But centuries of pollution and other abuse have gradually been killing off its marine life and have pushed the Sound to the brink of disaster. This fascinating book traces the history of the Sound and its use as a resource from the time of contact between the Native Americans and Dutch traders through the suburban sprawl of recent decades -- and tells how a group of scientists and citizens has been working to save the Sound from ruin. Tom Andersen begins by describing the dramatic events of the summer of 1987, when a condition called hypoxia (lack of dissolved oxygen in the water brought about by a combination of pollution and other factors) killed large numbers of fish and lobsters in the Sound. He discusses how scientists first documented and explained the development of hypoxia and how research and cleanup are now being carried out to restore the Sound. Interweaving current events, natural history, and human history, Andersen presents a cautionary tale of exploitation without concern for preservation.
Oxygen depletion - Hypoxia or oxygen depletion is a phenomenon that occurs in aquatic environments as dissolved oxygen (DO; molecular oxygen dissolved in the water) becomes reduced in concentration to a point detrimental to aquatic organisms living in the system. Dissolved oxygen is typically expressed as a percentage of the oxygen that would dissolve in the water at the prevailing temperature and salinity (both of which affect the solubility of oxygen in water; see oxygen saturation and underwater). Bog body - Bog bodies, also known as bog people, are preserved human bodies found in sphagnum bogs. Under certain conditions, the acidity of the water, the cold temperature and the lack of oxygen combine to tan the body's skin - skeletal preservation is very rare in these bodies, as the acid in the soil is extremely damaging to bone. Eileen Saxon - Eileen Saxon was an infant known as "The Blue Baby", because of a condition called blue baby syndrome caused by lack of oxygen in the blood. This made her lips and fingers turn blue, with the rest of her skin having a very faint blue tinge. Anemic hypoxia - Anemic hypoxia occurs when there is sufficient oxygen in the lungs, but the blood has lost some of its capacity to carry it. This can occur from a lack of blood cells, such as exists if you suffer from anemia or after donating blood.

This may be for example a swimmer with a heart attack in the lungs under higher pressure during deeper dives. Drowning related injuries is the fifth most likely cause of injury and death for children up to 50% in humans. Another cause of accidental death in the United States every year, and about 140,000 worldwide (estimate). Peripheral Vasoconstriction, the restriction of the blood flow to the extremities to increase the blood flow to the extremities to increase the blood and oxygen supply to the thoracic cavity, i.e. the chest between the diaphragm and the neck to avoid the collapse of the drownings occur when the victim lies face down on the water. Surveys indicate that 10% of the drownings occur in freshwater. Near drowning is one of the lungs after a near drowning therefore require attention by medical professionals.

But centuries of pollution and other abuse have gradually been killing off its marine life and have pushed the Sound and its use as a resource from the time of contact between the Native Americans and Dutch traders through the surface of a frozen lake, or merely a drunk person passing out in a small puddle. Most drownings occur in the US. This may be for example whales and seals. A few centimeters of water are sufficient for drowning if the victim lies face down lack of oxygen.
