Sometimes, it could be dark brown by being dyed during its industrial production process in order to alert people to its hazards. Sulfuric acid shows different properties depending upon its concentration (a.k.a its color). Its corrosiveness on other materials, like metals, living tissues or even stones, can be mainly recognized to its strong acidic nature and property. Sulfuric acid at a high concentration can cause very serious damage upon contact, as it not only causes chemical burns because of hydrolysis, but also secondary thermal burns via dehydration. It burns and can lead to permanent blindness if splashed onto eyes.
Due to the enormous amount of CFC’s used, leakages in spray cans, refrigerants as well as general use, the CFC gases were released into the atmosphere. As CFC’s were so inert they did not react in the troposphere and gradually made their way to the stratosphere. This is where the ultraviolet energy separated the C-Cl bonds and as a result Cl free radicals were formed which reacted with ozone under UV light and thus destroying he ozone layer. When the chlorine atoms reach the stratosphere they undergo photodissociation. The chlorine radicals rapidly
CADMIUM POLLUTION AND ANTHROPOLOGY by Courtney Van Gemert Cadmium toxixicity is of great concern to the world anthropologically. Cadmium is an element existing naturally in minute concentrations across terrestrial and marine environments, but greater excess levels observed are almost entirely anthropogenically introduced. Though cadmium has favorable chemical and physical properties conducive to wide use in special alloys, stabilizers, in rechargeable nickel-cadmium batteries, and as a control rod material in nuclear reactors, it is a toxic heavy metal of increasing environmental concern due to its wide variety of adverse effects . Cadmium is harmful to various organs, from kidneys to the central nervous system in vertebrates, including humans. In fish, neurological functions, intermediary metabolism, antioxidant activity, epithelial transport, and other physiological and biochemical systems are damaged by cadmium .All of these harmful bioinorganic effects are largely due to occupational or environmental exposure to in-excess levels of cadmium through inhalation or ingestion of fine air particulates and consumption of cadmium-exposed plants, animals, or water.
The Affects on Human’s and the Environment Katrina Doughty Everest University September 2011 Air pollution consists of gases and fine particles. Each type of air pollution has different effects upon the environment and human health. Air pollution affects are many, and they may be really harmful. Three factors determine the levels of air pollution are the amount of pollutants entering the air, the amount of space into which the pollutants are dispersed, and the mechanisms that remove pollutants from the air. Sulfur dioxide is a noticeable component in the atmosphere.
Carbon dioxide is an significant contributor to the enhanced greenhouse effect. It can result in trapping more of the heat that Earth is radiating into space and cause detrimental climate changes and rising sea levels. The main concern regarding the combustion of organic compounds is the result of incomplete combustion. Incomplete combustion occurs when there is not enough oxygen to completely burn the fuel to carbon dioxide and water, causing pollution and fuel inefficiency. For example: Pentane reacts with little oxygen to form
