Term	Acronym	Vocabulary	Vocabulary Type	Definitions
Biochemical Oxygen Demand	BOD	Aquatic Biodiversity Glossary	Glossary and Key Word List	Definition: A measure of the amount of oxygen consumed in the biological processes that break down organic matter in water. The greater the BOD, the greater the degree of pollution.
Biochemical oxygen demand	BOD	Nonpoint Pollution Source from Agriculture Glossary	Glossary and Key Word List	Definition: A quantitative measure of the strength of contamination by organic carbon materials.
Biochemical Oxygen Demand	BOD	Terms of Environment	Glossary and Key Word List	Definition: A measure of the amount of oxygen consumed in the biological processes that break down organic matter in water. The greater the BOD, the greater the degree of pollution.
Biochemical Oxygen Demand	BOD	Urban Watershed Management Research Terminology	Glossary and Key Word List	Definition: An operational measure of potential for depletion of dissolved oxygen by the biological and chemical degradation of organic material by bacteria.
Biochemical Oxygen Demand	BOD	NPDES Permit Writers Manual Glossary	Glossary and Key Word List	Definition: A measurement of the amount of oxygen used by the decomposition of organic material, over a specified time (usually 5 days) in a wastewater sample; it is used as a measurement of the readily decomposable organic content of a wastewater.
Biochemical Oxygen Demand	BOD		Abbreviation and Acronym List
Biochemical Oxygen Demand	BOD	Watershed Protection Glossary	Glossary and Key Word List	Definition: The amount of oxygen consumed by microorganisms (mainly bacteria) and by chemical reactions in the process of degrading organic matter in water.
biochemical oxygen demand	bod	Environmental Issues Terms & Acronyms	Glossary and Key Word List	Definition: A measure of the oxygen required to break down organic materials in water. Higher organic loads require larger amounts of oxygen and may reduce the amount of oxygen available for fish and aquatic life below acceptable levels.
Biochemical Oxygen Demand	BOD	Drinking Water Technical & Legal Terms	Glossary and Key Word List	Definition: The amount of oxygen consumed by microorganisms (mainly bacteria) and by chemical reactions in the biodegradation of organic matter.
Biochemical Oxygen Demand	BOD	National Pollutant Discharge Elimination System (NPDES) Glossary	Glossary and Key Word List	Definition: A measurement of the amount of oxygen utilized by the decomposition of organic material, over a specified time period (usually 5 days) in a wastewater sample; it is used as a measurement of the readily decomposable organic content of a wastewater.
Biochemical Oxygen Demand	BOD	CADDIS Glossary	Glossary and Key Word List
Biochemical Oxygen Demand	BOD	Sediment Total Maximum Daily Loads (TMDLs) Glossary	Glossary and Key Word List	Definition: The amount of oxygen per unit volume of water required to bacterially or chemically oxidize (stabilize) the oxidizable matter in water. Biochemical oxygen demand measurements are usually conducted over specific time intervals (5, 10, 20, 30 days). The term BOD generally refers to a standard 5-day BOD test.
Biochemical oxygen demand as measured in the standard 5-day test	BOD5		Abbreviation and Acronym List
Carbonaceous Biochemical Oxygen Demand	CBOD	NPDES Permit Writers Manual Glossary	Glossary and Key Word List	Definition: The biochemical oxygen demand of carbonaceous sources. This differs from BOD in that BOD measures both nitrogenous and carbonaceous sources, whereas CBOD excludes nitrogenous sources (e.g., nitrifying bacteria) from determination through the addition of a nitrification inhibitor.
Carbonaceous biochemical oxygen demand		N-STEPS Online Glossary of Terms	Glossary and Key Word List	Definition: Oxygen demand exerted by organic carbon compounds present; oxygen required to convert organic carbon to carbon dioxide.
Carbonaceous Biochemical Oxygen Demand	CBOD		Abbreviation and Acronym List
Chemical Oxygen Demand	COD	Environmental Issues Terms & Acronyms	Glossary and Key Word List	Definition: A measure of the oxygen-consuming capacity of inorganic and organic matter present in water or wastewater; the amount of oxygen consumed from a chemical oxidant in a specific test.
Chemical Oxygen Demand	COD	NPDES Permit Writers Manual Glossary	Glossary and Key Word List	Definition: A measure of the oxygen-consuming capacity of inorganic and organic matter present in wastewater. COD is expressed as the amount of oxygen consumed in mg/L. Results do not necessarily correlate to the biochemical oxygen demand (BOD) because the chemical oxidant can react with substances that bacteria do not stabilize.
Chemical Oxygen Demand	COD	Drinking Water Technical & Legal Terms	Glossary and Key Word List	Definition: An indirect measure of the amount of oxygen used by inorganic and organic matter in water. The measure is a laboratory test based on a chemical oxidant and therefore does not necessarily correlate with biochemical oxygen demand.
Chemical Oxygen Demand	COD	Terms of Environment	Glossary and Key Word List	Definition: A measure of the oxygen required to oxidize all compounds, both organic and inorganic, in water.
Chemical oxygen demand		Federal LCA Commons Elementary Flow List for Life Cycle Assessment	Glossary and Key Word List	Definition 1: A measure of the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrite [COD] [Original source: https://agclass.nal.usda.gov/mtwdk.exe?k=default&l=60&w=24649&s=5&t=2]. Definition 2: A measure of the amount of a water body's dissolved oxygen supply that would be used up in completely oxidizing added inorganic oxidizable compounds-such as in the oxidation of ammonia to nitrate. Biological oxygen demand (BOD) tests can only measure the biodegradable fraction of the total potential dissolved oxygen consumption by added wastes; however, COD tests may be used to measure the oxygen demand created by toxic organic or inorganic compounds as well as by biodegradable substances. A standard COD test, therefore, can be used to evaluate many industrial type wastes not readily analyzed for water quality factors by the sewage-oriented BOD test.
Chemical Oxygen Demand	COD		Abbreviation and Acronym List
Chemical Oxygen Demand	COD	Watershed Protection Glossary	Glossary and Key Word List	Definition: A measure of the oxygen-consuming capacity of inorganic and organic matter present in water; the amount of oxygen consumed from a chemical oxidant in a specific test.
Chemical Oxygen Demand	COD	National Pollutant Discharge Elimination System (NPDES) Glossary	Glossary and Key Word List	Definition: A measure of the oxygen-consuming capacity of inorganic and organic matter present in wastewater. COD is expressed as the amount of oxygen consumed in mg/l. Results do not necessarily correlate to the biochemical oxygen demand (BOD) because the chemical oxidant may react with substances that bacteria do not stabilize.
Ultimate Biochemical Oxygen Demand	UBOD	Sediment Total Maximum Daily Loads (TMDLs) Glossary	Glossary and Key Word List	Definition: Long-term oxygen demand required to completely stabilize organic carbon in wastewater or natural waters.
