Biological Oxygen Demand (BOD) is a measure of the oxygen used by microorganisms to decompose this waste. If there is a large quantity of organic waste in the water supply, there will also be a lot of bacteria present working to decompose this waste. In this case, the demand for oxygen will be high (due to all the bacteria) so the BOD level will be high. As the waste is consumed or dispersed through the water, BOD levels will begin to decline. Nitrates and phosphates in a body of water can contribute to high BOD levels.
Making the world better, one answer at a time. The condition of deficient oxygen is hypoxia, and the condition of no oxygen is anoxia. Blood cells are aerobic so they need oxygen to survive. If you have below normal oxygen levels, you're not providing your blood with its fuel; you're basically starving your blood cells.Blood delivers oxygen to your tissues before returning to your lungs to fill up again. So if your blood isn't getting enough oxygen, neither will any other part of your body.noxia is the medical term meaning absence of oxygen. an/ox/ia without/oxygen/condition of condition of without oxygen Anoxia means lack of oxygen. anoxia Hypoxia-meaning w â¦ ithout oxygen or it can be Ischemia ---which means lack of oxygen usually due to lack of blood.
