Ozone

Introduction Ozone was first discovered in 1785 by Dutch chemist Martinus van Marum when he was conducting experiments involving electrical sparking above water when he noticed an unusual smell, which he attributed to the electrical reactions. In 1840, ozone was first acknowledged by Christian Friedrich Schönbein, who determined the same pungent odor produced during sparking experiments was caused by an unknown compound and recognized it as being the same as that produced after a lightening flash

1. What is ozone? Ozone (O₃) is a type of gas comprised of three oxygen atoms, and is both colourless and odourless. 2. Explain the paradox that ozone is considered a health hazard, yet is essential to life on Earth. Ozone is both a health hazard and vital for life on Earth because if the gas enters the lungs, or comes in contact with any living tissue, it can result in damage in that particular tissue and illness. However, ozone is important as it shields life on Earth from the sun’s dangerous

1. In terms of ozone concentration, one difference that can be seen between the Shenandoah area and Richmond relates to the levels throughout the days in each individual month. In general, the Shenandoah has a more consistent ozone concentration throughout a day in a month than Richmond. For example, in the month of April, the ozone concentration in the Shenandoah area relatively stayed around 50 ppb while the ozone concentration in Richmond fluctuated from 25 to 45 ppb. For the Richmond graphs,

The Effects of Ozone Pollution The term "ozone" has appeared in numerous magazine and newspaper articles and has been a subject of discussion on both radio and television. Despite all the publicity surrounding this term, however, many people are still confused by it. The confusion arises from the fact that ozone is both beneficial and harmful. We know that the ozone layer in the upper atmosphere acts as a filter for the sun's ultraviolet rays, reducing the amount of radiation that reaches the

shown that exposure to human by ozone is effective to health and it is increasing worldwide. Air pollution is the serious global threat which is increasing continuously and the ground level concentration of ozone is major problem in present and also in future. Presents projected average daily 8-h maximum ozone levels for future using the raw and calibrated climate model outputs. The 95% projections intervals accounts for uncertainties in the associations between daily ozone levels, and daily meteorology

The ozone depletion has been well documented to negatively affect planet Earth for years. The ozone is a thin layer of the Earth´s atmosphere which is responsible for absorbing the sun's harmful ultraviolet light ( What is Ozone Layer?,2017). The loss of ozone on earth will take a toll on human health, plants and marine ecosystems, ultimately resulting in a planet that does not support living things. Today, this manifests in climate change. It is easy for many to confuse these two issues, although

Good ozone & Bad ozone Ozone occurs in two layers of the atmosphere. The ozone that is commonly associated with ozone depletion and the ozone “hole” is in the stratosphere, a layer that extends upward from about 10 to 30 miles (15 to 50 kilometers) above the earth. This “good” ozone shields life on earth from the sun's harmful ultraviolet rays (UV-b). The layer surrounding the earth's surface is the troposphere. Here, ground-level or "bad" ozone is an air pollutant that damages human health,

The ozone layer is a specific area in the stratosphere of maximum ozone concentration. Ozone in the stratosphere forms naturally and protects us from damage that can be caused by solar radiation such as skin cancer. In the 1970s chemists discovered that certain chemicals could travel into the upper atmosphere and damage the protective ozone. Ever since this was discovered scientists, government, and citizens have been making efforts to control and reverse the damage done to the ozone. In 1987 a treaty

stratosphere, and the ozone layer which sits in the lower area of the stratosphere. The troposphere layer is where a lot of human activity occurs, such as planes and mountain climbing. The next layer is the stratosphere and this is where the ozone layer is located as well. The ozone layer helps protect people from ultraviolet radiation that mainly come from the sun. The ozone layer can be different depending on the season and the location. Over the past few years, the ozone layer has been depleting

that all humans, no matter where or how they live depend on, water and air. Both are essential for life but air also protects all of us and it is therefore understandable that the response to the depletion of the ozone layer became international. This essay will look at what the ozone layer is, why it was depleting, how the international response to this situation developed and what this collaboration means for our future. The envelope of gases surrounding the earth is called the atmosphere and
