The total number of milliliters of titrant Utilized in techniques 6-eight equals the entire dissolved oxygen in the sample in mg/L. Oxygen saturation is temperature dependent - gas is more soluble read more in cold waters, therefore chilly waters frequently have greater dissolved oxygen concentrations.

While these fauna will continue to exert biochemical oxygen need as they die, that has a tendency to occur inside a far more steady advanced ecosystem together with higher trophic ranges.[3]
