Chemical oxygen demand (COD) is a measure of the amount of organic matter in water that can be oxidized by a chemical oxidant. It is an essential parameter in water analysis as it indicates the level of organic pollution in water. High levels of COD can indicate the presence of organic pollutants such as pesticides, herbicides, and industrial effluents.
