What Biochemical Oxygen Demand (BOD) Measures?

29 October 2022 Jefy Environmental Engineering, Water Pollution

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

14 May 2022 Jefy Environmental Engineering

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.

Landfills – Causes, Operation and Life Cycle- Everything you should know

10 November 2021 Jefy Environmental Engineering, Land Pollution

Landfills are a regular occurrence all over the world, owing to the rising volume of trash generated by our homes, schools, offices, hospitals, and markets. The rising number of landfills around the world is largely due to increased urbanisation and population growth rates. As the world’s population and cities develop, so does the need for goods and commodities. Consequently, the amount of solid trash produced also increases. They eventually reach landfills. In this blog, let’s go on a trip to a landfill and understand its operation, lifecycle and impacts.

Land Pollution Causes -Top 6 causes explained

2 November 2021 Jefy Environmental Engineering, Land Pollution

The causes of land pollution can be direct, such as when toxic chemicals are dumped directly on a site, or indirect, such as when harmful chemicals leak through the soil from particulates produced through vehicle exhausts or combustion. We must understand the causes of soil pollution in order to develop and execute solutions.
