It determines the amount of dissolved oxygen that is consumed by aerobic biological microorganisms in water. It is measured by the amount of oxygen that is consumed per liter of sample during 5 days of incubation it is in milligrams.

What is TOD BOD in water quality measurement?

There are three OD's used Total Oxygen Demand (TOD), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) They all measure the amount of oxygen that would be required to consume organic material in the water, BOD is the lowest (usually) as it measures demand from microbes eating easily digested organics (sugars etc), COD measures the demand from all other organics (alcohols etc) measured by digesting the material in strong chemical oxidants, and TOD is the total of the two. Oxygen demand is important to know in waste handling as reducing the oxygen in receiving stream can harm fish and other aquatic life.


Does epinephrine decrease myocardial oxygen demand?

Yes, epinephrine can decrease myocardial oxygen demand by increasing coronary perfusion, improving cardiac output, and reducing systemic vascular resistance. However, high doses of epinephrine may increase myocardial oxygen demand due to its positive inotropic and chronotropic effects.


Oxygen is required in biological systems for what?

Oxygen is required in biological systems for cellular respiration, which is the process by which cells convert oxygen and glucose into energy, carbon dioxide, and water. This energy is used to fuel various cellular activities essential for life.


What is the oxygen demand for a human?

In Rest a normal human (65 Kgs Body Weight) will need 250ml/min. of oxygen.Depending on the activity the body might consume 15 times as much oxygen as it needs in rest.


Could oxygen in the atmosphere be conconsiderd an abiotic factor?

Yes, oxygen in the atmosphere is considered an abiotic factor. Abiotic factors are non-living components that can influence living organisms. Oxygen plays a critical role in many biological processes and is essential for the survival of aerobic organisms.

What is a biological oxygen demand?

A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.

Biological Oxygen Demand


What is mean chemical oxygen demand-?

The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.


What is the different between biochemical oxygen demand and biological oxygen demand?

Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .


How Biological Oxygen Demand (BOD) affects the aquatic life?

Biological oxygen demand is a measure e of how much oxygen microbes will use in decomposing organics in the water. It isa measure of how much oxygen is required to diffuse into the water to keep the ecosystem aerobic.


How does the decomposition of algae contribute to an increase in biological oxygen demand?

When algae decompose, they release organic matter into the water. Bacteria break down this organic matter, using up oxygen in the process. This increase in bacterial activity leads to a higher demand for oxygen in the water, which can decrease oxygen levels and harm aquatic life.


What does bod stand for?

BOD commonly stands for "Biochemical Oxygen Demand." It is a measure of the amount of dissolved oxygen consumed by biological organisms in water. High BOD levels indicate organic pollution and can lead to oxygen depletion in aquatic systems.


Why is there a demand for chemical oxygen?

There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.

What is organic loading rate?

Organic loading rate (OLR) is a measure of the amount of organic matter being fed into a biological treatment system per unit of time. It is typically expressed in terms of chemical oxygen demand (COD) or biochemical oxygen demand (BOD) per unit volume of the system. OLR is an important parameter in designing and operating biological treatment systems such as anaerobic digesters or activated sludge systems.
