|Abstract Title:||Why should we need to monitor Emission of a Cement Plant?|
|Presenter Name:||Mr Ashis Kumar Chakraborty|
|Session Choice:||Continuous Emission Monitoring|
Abstract Information :
A substance discharged into the air, especially by an internal combustion engine or equipment /machine.
The act of emitting or sending forth energy, in the form of heat, light, radio waves, etc, emitted from a source. A substance, fluid, etc, that is emitted; discharge. A measure of the number of electrons emitted by a cathode or electron gun.
Air pollution has always accompanied civilizations. Pollution started from prehistoric times when man created the first fires. Metal forging appears to be a key turning point in the creation of significant air pollution levels outside the home. The burning of coal and wood, and the presence of many horses in concentrated areas made the cities the cesspools of pollution. It was the industrial revolution that gave birth to environmental pollution as we know it today. A pollutant is a waste material that pollutes air, water or soil. Three factors determine the severity of a pollutant: its chemical nature, the concentration and the persistence. Pollution has cost. Manufacturing activities that cause air pollution impose health and clean-up costs on the whole society, whereas the neighbors of an individual who chooses to fire-proof his home may benefit from a reduced risk of a fire spreading to their own houses. If external costs exist, such as pollution, the producer may choose to produce more of the product than would be produced if the producer were required to pay all associated environmental costs.
Sources and causes
Air pollution comes from both natural and human-made (anthropogenic) sources. However, globally human-made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation.
Dust consists of particles in the atmosphere that come from various sources such as soil, dust lifted by weather (an aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, skin cells, burnt meteorite particles, and many other materials which may be found in the local environment. First of all we have to understand the danger and its control. Industries can be identified to like Thermal Power Plant, Steel making process, Cement plant and Chemical plant.
