Aerosol As A Negative Effect Essay, Research Paper Aerosol as a Negative Effect in Society If you were to look at a few of the products sitting around or maybe some you are using, you probably wouldn’t think twice about the effects they have on society. Many products that are used everyday were produced with positive affects in mind, but what many people don’t realize is that many have harmful affects. Many products have directly and indirectly destroyed people’s lives, changing the way we view these products. In Frankenstein, written by Mary Shelley, Frankenstein constructed his monster in an effort to create life. When the monster began to be rejected from society, he insisted on becoming a threat to man. Many products we use everyday are changing people’s lives and

changing the environment; Not for the better like they were intended, but for the worse. Like Frankenstein’s monster, aerosol was produced with positive interest in mind but has risen as a major threat and concern to today’s society. The first use, which will later be evolved into aerosol, of compressed air was in the early 1700’s. Compressed air was used in jackhammers along with many other tools that required pressure to operate them. Compressed air is able to travel through a small air turbine to turn a shaft, or can be expanded through a nozzle to produce a high-speed jet, as in a paint sprayer. A Swiss mathematician and physicist, named Daniel Bernoulli, made this discovery. He used the concept of pressurizing aerosol in a container to dispense a wide variety of

substances in the form of fine sprays, foams, or liquid streams. Bernoulli’s first Russell 2 purpose of using aerosol was to disprove the concept that as the speed of a moving fluid increases, the pressure within that fluid decreases. Bernoulli’s Principle states that the total energy in a steadily flowing fluid system is a constant along the flow path. An increase in the fluid’s speed must therefore be matched by a decrease in its pressure. (Compressed Air) Aerosol is a product that is used everyday by almost everyone. Aerosol is used in spray paint cans, hairspray containers, and even some whipped cream dispensers. Since aerosol can be used in liquid and air dispensers, it has several advantages. Aerosol dispensers allow for easier to handle containers. Instead of having

to pump a material out of a container, aerosol has made it as easy as pressing a button. The aerosol containers are also much easier and convenient than pump dispensers. Aerosol can easily be made, and as a result it is cheaper than the pump containers that require many parts and accessories. The disadvantages of aerosol are immense. The affects of aerosol have left a mark on the ozone can never be corrected. Over Antarctica, the stratospheric ozone has been depleted over the past 15 years. (Part I) In the 1970’s some scientists concluded that ozone concentrations were slowly lessening. These scientists have concluded that the uses of CFC’s are the cause of the destruction of the ozone. When CFC’s are dispensed, they rise to the upper atmosphere and destroy the ozone. When

CFC’s are decomposed by ultraviolet light, they free a chlorine atom that reacts with the ozone to form new compounds. This process destroys the ozone. (Compton’s Encyclopedia) The effects CFC’s have left on the ozone are referred to as the ozone hole. The press and public, with the problem of global warming, often confuse the ozone hole. (Part I) If the stratospheric ozone layer were to become less dense, more ultraviolet rays would reach the Earth, causing genetic damage to many organisms and leading to increased incidence of skin cancer in Russell 3 humans. (Compton’s Encyclopedia) The first global agreement to restrict CFC’s came with the signing of Montreal Protocol in 1987. This agreement was aimed to reduce them by half by the year 2000. (Part I) Along with
