What is the full form of BOD in environment studies?

What is the full form of BOD in environment studies?

Biochemical oxygen demand (BOD) is the amount of dissolved oxygen (DO) needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.

What is meant by BOD Class 12?

Biochemical oxygen demand (BOD) is defined as the amount of oxygen used by bacteria and other microorganisms during the process of decomposition of organic matter under aerobic (oxygen is present) conditions at a particular temperature and in specific time periods.

What is meant by BOD and COD?

The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.

What is the full form of BOD and pan?

BOD – Biochemical Oxygen Demand. PAN – Peroxy acetyl nitrate.

What is the full form of BOD Mcq?

BOD or Biochemical Oxygen Demand measures the degree of impurity of a water body or sample due to organic matter. BOD is the amount of dissolved oxygen needed by aerobic microbes to breakdown the organic matter present in the water body. So, the correct answer is extend of pollution with organic matter.

What is BOD PDF?

Biological oxygen demand (BOD), also known as biochemical oxygen demand, is a bioassay procedure that measures the dissolved oxygen (DO) consumed by bacteria from the decomposition of organic matter.

What is BOD sensor?

The BOD Sensor is the mercury-free and reliable solution for BOD determination. Easy to handle, quick and easy to read. A microprocessor-controlled pressure transducer transfers the BOD value directly to the display: results are displayed directly in mg/l with no need for further calculation.

Why BOD is important?

The BOD is an important parameter for assessing water quality. It deals with the amount of oxygen consumption (mg O2 L− 1) by aerobic biological organisms to oxidize organic compounds. Sewage with high BOD can cause a decrease in oxygen of receiving waters, which in turn can cause the death of some organism.

What is bod in water quality?

Biological Oxygen Demand (BOD) is one of the most common measures of pollutant organic material in water. BOD indicates the amount of putrescible organic matter present in water. Therefore, a low BOD is an indicator of good quality water, while a high BOD indicates polluted water.

What is the full form of BOD?

The exact full form of BOD is Biochemical oxygen demand. Standard method for indirect measurement of the amount of organic pollution in a sample of water. BOD test procedure is based on the activities of aerobic micro organisms and bacteria.
