Prolonged administration of highly concentrated oxygen can potentially damage the lung lining tissues and air sacs a condition known as pulmonary oxygen toxicity. The risk for this side effect of oxygen therapy comes into play primarily when patients on home treatment increase the oxygen flow rate to a level higher than prescribed.

Live ChatFor example where a heavy load is placed on a water source the water may become anaerobic as a result of a lack of oxygen when effluent with a high oxygen demand consuming a great deal of oxygen is introduced and may tip over. In another case the biological capacity of a sewage treatment plant can be tested by comparing the BOD

Live ChatBiological oxygen demand measures the amount of oxygen used by microorganisms in the oxidation of organic matter. When there are too many phosphates in aquatic systems algae proliferates dies and then aerobic bacteria decomposes them starving the water of oxygen and killing bacteria and other aerobic creatures.
