WebSignificance of BOD. The significance of BOD is that it is a measure of the amount of dissolved oxygen that is used up by microorganisms as they break down organic matter in water. The higher the BOD, the more oxygen that is being use up and the more polluted the water is. This makes BOD an important indicator of water quality. WebTemperature. Temperature is one of the biggest factors that directly affects dissolved oxygen. Temperature itself is a measurement of the energy of motion within a system. As temperature increases, particle motion increases. When temperature climbs, the particles, molecules, atoms, etc. get more and more energy.
