AIR POLLUTION Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems

Fracking Hydraulic fracturing‚ also known as fracking‚ is the process of removing once unattainable natural gas from shale formation deep underground. The fracking process was developed by Halliburton in the 1940s as a technique to stimulate gas well production. Vertical holes are drilled deep into the subsurface of the ground‚ and horizontal extensions are drilled at the bottom of the well at an average depth of 8000 feet. Once the holes are drilled‚ water is mixed with chemicals and

Various researchers had worked in the field of AE testing. A brief review of the work carried out in this area is explained in this section. Ohtsu et. al [1994] studied the history and development of AE. According to them AE research was first carried out in 1950 by J. Kaiser when he worked on metals. B.H Scofield in 1954‚ initiated the use of AE terminology wise in USA. T.F Drouillard found that first report on an experiment carried out with the help of AE was published in Japan. At the time of
