Biochemical Oxygen Demand or BOD gives a measure of the amount of oxygen that the microbes utilize to degrade organic materials in a water body. Also, BOD measures the chemical oxidation of inorganic materials i.e., the removal of oxygen from water via a chemical reaction. The BOD value is generally expressed in milligrams of oxygen used per litre of the sample over a 5-day incubation period at 20 °C, and it is frequently used as an estimate of the degree of organic pollution in water. The reduction of BOD is used in evaluating the efficacy of wastewater treatment systems.

The Montreal Protocol is an international pact that aims to protect the ozone layer by phasing out the manufacture of a variety of ozone-depleting compounds. It promotes international cooperation in reversing the rapid drop in ozone concentrations in the atmosphere.
Countries committed to phasing down the manufacture and consumption of certain ozone-depleting substances under the protocol.
The Ozone Layer Depletion – Effects and Causes
The ozone layer is an area of the earth’s stratosphere that contains high levels of ozone (O3) and protects the planet from the sun’s harmful ultraviolet rays. It can absorb roughly 97-99 percent of the sun’s damaging UV radiation, which otherwise can kill life on the Earth.
