On April 26, 1986, the Number Four RBMK reactor at the nuclear power plant at Chernobyl, Ukraine, went out of control during a test at low-power, leading to an explosion and fire that demolished the reactor building and released large amounts of radiation into the atmosphere. After death, decomposition releases carbon into the air, soil and water. The water flows out under the gill's cover and this process is repeated. For example, flat kaolinite crystals transform into needle-like mullite crystals. Higher BOD indicates more oxygen is required, which is less for oxygen-demanding species to feed on, and signifies lower water quality. Decomposition begins several minutes after death with a process called autolysis, or self-digestion. 2. The amount of dissolved oxygen used up by aerobic microorganisms to decompose the organic matters present in a sample of water is termed Biochemical Oxygen Demand or Biological Oxygen Demand (BOD).
