History of ozone: In 1785, the Dutch chemist Martinus van Marum was directing experiments including electrical starting above water when he saw an uncommon scent, which he credited to the electrical responses, neglecting to understand that he had in truth made ozone. A half century later, Christian Friedrich Schönbein saw an indistinguishable impactful smell and remembered it from the odor frequently taking after an electrical jolt. In 1839, he prevailing with regards to confining the vaporous compound and named it "ozone", from the Greek word ozein (ὄζειν) signifying "to smell”. [6] For this reason, Schönbein is by and large credited with the revelation of ozone. The formula for ozone, O3, was not decided until 1865 by Jacques-Louis …show more content…
Ultraviolet light also contributes to cataract which is a condition where the eye becomes cloudy and the vision is blurred. Skin deterioration and immune inhibition are a result of UV radiation. (Bais et al., 2015) Environmental Impacts Ozone depletion has adverse effects on agriculture, forestry, marine ecosystems and polar ice caps. Aquatic food webs are affected in terms of development and growth; this disrupts biological processes. Due to more ultraviolet radiation reaching the earth’s surface, polar ice caps melts and this increases the sea level, which in turn can cause major flooding in low coastal regions. There is a decline in phytoplankton, as water is transparent and due to the high amounts of UV radiation reaching 0.5 meters below surface, it intoxicates the phytoplankton.

Therefore, the idea of having ozone in your body is not favourable at all as ozone is an oxidant. Nevertheless, this is overcome by the fact that ozone can be used to treat many diseases, including inflammatory bowel disease, viral infections, dry age-related macular degeneration, and neurodegenerative diseases. For ozone to have any effect at all it needs to be introduced into the body. This could either be through the rectum or via the blood. Ozone is added to small amounts of blood, as a mixture of ozone and oxygen. This procedure needs to be carried out very carefully to prepare a safe dosage, in which the ozone must be no more than 5% only. This ozonated blood in then returned back into the circulation in various ways. This way of using ozone as a therapy is called ozonated autohaemotherapy
These applications include pesticide, herbicide, defoliating agent such as Agent Orange, cleaning agent and electrical insulation. Consequently, human exposure to dioxin is not a recent phenomenon and the dangers of dioxin are not unknown. Only in recent years, especially after the Vietnam War, has the media concentrated on the dangers and impact of dioxin. The physical effect of exposure to dioxin was first seen in skin diseases developed by chemical plant workers in 1895. Exposure to dioxin results in a type of skin disease like acne called "chloroacne," since its cause was initially and incorrectly linked to chlorine gas.
Oxygen, inhaled bronchodilators, inhaled steroids, combination inhalers, oral steroids, phosphodiesterase-4 inhibitors and theophylline are effective medications for COPD (Mayo Clinic, 2016). “Patients with COPD have persistent high levels of CO2, their respiratory centers no longer respond to increased levels of CO2 by stimulating breathing. Therefore, COPD patients with more severe hypoxemia are at higher risk of CO2 retention from uncontrolled CO2 administration” (Van Houten, p. 13). For nurses, “It is important to administer the lowest amount of O2 necessary to patients” (Van Houten, p. 13). Some COPD medicines are used with inhaler and nebulizer devices. It is important to teach patients how to use these devices correctly. (Potter & Perry,
The light released by the sun consists of three frequency bands of radiation: infrared, visible and ultraviolet. Out of the three frequency bands, the ultraviolet light is damaging to most humans. Ultraviolet (UV) radiation divided into three categories: UVA, UVB, and UVC. UVA radiation passes through the skin without burning the surface layers. These rays can penetrate to a depth of 0.04 inches and causes damage to cell membranes and the immune system. UVA radiation has been linked to skin cancer, early aging and wrinkling of the skin. UVB radiation is responsible for the painful red burn people get after a long period of exposure to the sun. UVB rays also cause skin cancer and damage to the cornea and lens of the eye. The third category, UVC radiation, is generally absorbed by the Earth’s atmosphere and is not considered harmful.
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
Oxygen is widely used in both chronic and acute cases, in emergency medicine, at hospital or by emergency medical services (Nicholson, 2004 ). Just like any other form of medication oxygen is a drug that if used incorrectly could cause potential harm, even death (Luettel, 2010 ). Oxygen is admitted to the patient with chest pain for two main rationales. The first is by increasing arterial oxygen tension, which in opposing causes a decrease to the acute ischemic injury, and thus over time the entire infarct area (Moradk...
In conclusion, the respiratory system contributes to homeostasis by obtaining O2 from and eliminating CO2 to the external environment. All of the body’s cells need an adequate amount of O2 to use in oxidizing nutrient molecules to generate ATP. For example brain cells, which are highly dependent on the continual supply of oxygen, will die if they are deprived of O2 for more then 4 minutes. It is evident that the precious respiratory system can be damaged from a variation of chemicals found in the atmosphere. This can range from automobile fumes to household cleaning products. Clearly cigarette smoke is a clear threat to the respiratory system because of the tar and other constituents that enter the lungs and should be avoided. The respiratory system should never be taken for granted, as it is one of the most important systems in our body.
The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).
Increasing the percentage of partial pressure of oxygen in the alveoli and enhances its diffusion into the capillaries. Supplemental oxygen therefore improves oxygenation of the blood and tissues in patient with pneumonia (Scott, Brooks, Peiris, Holtzman & Mulholland, 2008).
A brief history of the study of the oxygen effect will give some insight into the intensity of study and the ever changing attitudes and theories surrounding it. The first acknowledged study was made by Swartz in 1912. His contribution was realized during an experiment involving a radium applicator being used upon his arm. Swartz noticed that if he pressed the applicator to his skin with increasing force, a lessened reaction occurred. His idea was that the lessened blood flow resulted in the increased resistance. After Swartz, there was Holthusen in 1921. Holthusen irradiated the eggs of Ascaris, a small intestinal roundworm and noticed that if the irradiation took place in an anoxic, or oxygen free, environment, the resistance of the eggs was increased. He hypothesized that this was due to the halting of the cell cycle in the absence of oxygen, which was not the actual cause. (Biggar & Storey, 2009) Following Holthusen’s footsteps, Petry conducted a study involving the irradiation of vegetable seeds in varying levels of oxygenation. He found a correlation between the amount of oxygen present and the degree of success of germination of the seeds. The first real study to be published in English was done by Mottram in the 1930s. Mottram studied the su...
...cations. Many people will find that amount of sunlight they receive has little or no impact on the state of their psoriasis, but in the cases where the light therapy has worked, it seems to reduce the appearance of the lesions greatly. Obviously, the risk of the UV light therapy is the possible threat of skin cancer.
Human life depends on the presence of food, water and oxygen in order to sustain the body’s various functions. Every cell in the body needs oxygen to carry out its functions, including converting food to energy, reproduction, repairing damage, and more. The function of the respiratory system is to supply oxygen to the body. You may not know it, but you normally
The basic set of reactions that involve this process are: Cl + O3 -->ClO + O2 and ClO + O -->Cl + O2 The net result: O3 + O -->2O2 Chlorine is initially removed in the first equation by the reaction with ozone to form chlorine monoxide. Then it is regenerated through the reaction with monatomic oxygen in the second equation. The net result of the two reactions is the depletion of ozone and atomic oxygen.6 Chlorofluorocarbons (CFCs), halons, and methyl bromide are a few of the ozone depletion substances (ODS) that break down ozone under intense ultraviolet light.
Probably the most commonly used word by your dermatologist, your beautician, your pharmacist or just the girl next door, and for a good reason. The sun’s damaging UV rays can single-handedly destroy your skin over time and in some cases even cause irreparable damage. It will burn your skin, dry it out, destroy collagen fibers and predispose you to cancer. Whether it’s a scorching sun or not, whether you are outdoors or not, sunscreen is an everyday must-wear. You have a choice.
In 1989 a California based company called Masimo invented a revolutionary was of measuring the accurate value of oxygen in the
Air is vital to all living beings including plants & animals are dependent on air oxygen for generation of valuable life energy. Body cells take up oxygen from blood and generate energy from food in the form of Adenosine triphosphate (ATP). This biochemical generation of Adenosine triphosphate (ATP) is a basic requirement to sustain life on
