Abstract
Biological processes regulate the dissolved oxygen concentration in water through oxygen production in photosynthesis and oxygen demand in respiration. In this chapter, a way of measuring photosynthesis and respiration in the water column will be discussed, and the significance of the resulting data will be explained. The biochemical oxygen demand (BOD) and the chemical oxygen demand (COD) also are time-honored procedures used in water quality evaluation. These two methods of estimating oxygen demand in natural waters and effluents will be discussed.
