  • Acid Rain - 1,289 words
    Acid Rain Pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous, to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or cloud vapors. The acidity of substances dissolved in water are measured by their pH levels. Normal precipitation pH levels fall between 5.0-5.6.2 When levels fall below these numbers, then the precipitati ...

  • Air Quality - 1,726 words
    Air Quality Air Quality & Dispersion Today, the air quality aspect of ARL research is by far the dominant theme, but distinctions among the themes remain somewhat vague. For example, the models developed for emergency response purposes are among those used for air quality prediction. The Air Quality and Dispersion theme is one of the strongest ties that binds ARL's components together. ARL is not heavily involved in the pure science of the business. Instead, ARL focusses on the need to assemble integrated understanding and models from all available sources, to develop the capability to predict changes in air quality that will follow changes in emissions, or that will occur as a result of met ...

  • Anthrax Vaccination Program - 1,394 words
    Anthrax Vaccination Program On May 18, 1998, Secretary of Defense William Cohen approved a plan to vaccinate all U.S. service members for anthrax. This plan has caused a fierce ethical debate over the legitimacy of this vaccination. The Department of Defense claims the vaccination is completely safe and has been in use for decades. Some doctors dispute this claim, and contend the vaccination may not be effective against weapon versions of anthrax. Many service members have refused the vaccination and have either separated or faced formal punishment for their decision. The Bioport Corporation of Lansing Michigan is the only company that produces the anthrax vaccine. According to a Phoenix Tim ...

  • Blood Is A Fluid Substance That Circulates In The Arteries And Veins Of The Body Blood Is Bright Red Or Scarlet When It Has B - 1,393 words
    Blood is a fluid substance that circulates in the arteries and veins of the body. Blood is bright red or scarlet when it has been oxygenated in the lungs and passes into the arteries; it becomes bluish red when it has given up its oxygen to nourish the tissues of the body and is returning to the lungs through the veins and the tiny vessels called capillaries. In the lungs, the blood gives up the carbon dioxide wastes it has taken from the tissues, receives a new supply of oxygen, and begins a new cycle. This movement of blood is brought about by the coordinate activity of the heart, lungs, and blood vessels. Blood is composed of a yellowish fluid, called plasma, in which are suspended the mi ...

  • Book Of Nod - 1,462 words
    Book Of Nod The preface to this book is very cool. I know that this book is totally fictional, and is in no way real, but the preface makes the book sound like it was written from ancient scrolls and manuscripts that were uncovered through his journies. The preface describes how he was able to get all of the material to write the book. It is incredibly detailed and extreamly vague at the same time if that is possible. With all of the history and this mans travels in the preface, it seems like the book is written from fact and really gives the book a nice read to it. Chapter Two: The Chronicals of Caine This is the begining of Caine's adventure, this story was written in a biblical type of st ...

  • Car Pollution - 333 words
    Car Pollution Air Pollution "According to the United States Environmental Protection Agency, driving a car is the single most polluting thing that most of us do." This is not a new problem. In the 1950's the Los Angeles smog made head-line news. Car exhaust causes health problems. There are many solutions to the problem. Laws were enacted as long as twenty years ago to control pollution caused by cars. Since then laws have been made, such as special nozzles on gas pumps that prevent vapor from getting into the air. We also have more tests on cars to make sure cars are maintained in a way that protects our environment. In cities, laws ask that more people ride on buses, and employees that dri ...

  • Carbon Dioxide - 319 words
    Carbon Dioxide Carbon dioxide has been rising in the atmosphere throughout time. Recently though, the levels of carbon dioxide have been increasing at a more alarming rate. The cause of this is a direct result of mans burning of fossil fuels. We know that every action we make, as humans, will have some effect on the environment around us and those effects can be either good or bad. The rising levels of carbon dioxide in the atmosphere may potentially inflict some negative effects on our environment. The termed used to describe the rise in CO2 in the atmosphere is the greenhouse effect. Major greenhouse gasses include carbon dioxide, water vapor, and methane. Greenhouse gasses collect in the ...

  • Changes Of Matter State - 1,344 words
    Changes Of Matter State To define matter, one would say that it is something that occupies space and has weight. Matter naturally occurs in three phases: solid, liquid, and gas. Changing from a solid to a liquid, liquid to gas, etc. can be referred to as a change of state. Changes of state (or phase) effect our everyday lives. This chapter on changes of phase should actually be called Energy Transfer. The whole basis on changing a substance's state is that it is using energy to get from one state to another. To understand the "real" difference in the phases of matter, you must understand the difference in the energy of the phases. Energy is found inside matter. You can think of this energy a ...

  • Chernobyl - 1,198 words
    Chernobyl April 26th 1986 marked the date of the worst nuclear accident to ever occur. Chernobyl, a nuclear power plant in Russia was undergoing routine safety tests that envolved running the reactor on less then full power, followed by a standard shut down. At Chernobyl's reactor number 4 a specific test was designed to show that a coasting turbine could produce enough power to pump coolant through the reactor core while waiting for electricity from diesel generators. During the test turbine feed valves were closed to initiate turbine coasting, and automatic control rods were withdrawn from the core. When the steam valves to the turbine close, the pressure in the reactor should go up causin ...

  • Chernobyl - 1,436 words
    Chernobyl The Chernobyl disaster on April 26, 1986 is described as one of the most frightening environmental disasters in the world. The plant was made up of four graphite reactors, which were the most modern Soviet reactors of the RBMK-type. Two more of these reactors were still under construction at the station. Chernobyl was an obscure town in north central Ukraine (former Soviet Union) on the Pripyiat River near the Belarus border. Immediately its name was joined to the Nuclear Power Plant located twenty-five kilometers upstream. The plant is actually located fifteen kilometers northwest of the city. It is not only the radioactive mess left that strikes fear. Nineteen similar stations ar ...

  • Child Labor - 1,523 words
    Child Labor Child Labor In the past few years, a great deal of attention has been drawn to the global problem of child labor. Virtually everyone is guilty of participating in this abusive practice through the purchase of goods made in across the globe, usually in poor, developing nations. This issue has been around for a great length of time but has come to the forefront recently because of reports that link well known American companies like Wal-Mart and Nike to the exploitation of children. Prior to this media attention, many Americans and other people in developed nation were blind to the reality of the oppressive conditions that are reality to many.

  • Combustion Carbon Dioxide - 1,146 words
    COMBUSTIOn & carbon Dioxide Research By Rabon Hutcherson II. Combustion and carbon dioxide, what are they? When people think of combustion they probably think of simple just bursting into flames; and for carbon dioxide you probably think of what we breath out and what plants take from the air and turn to oxygen. Even though these thoughts are true there is much more to combustion and carbon dioxide. Things you might not think of about combustion are, mathematical equations, models, solutions and chemical reactions, and for carbon dioxide dry ice, combustion and it being a solid. All of these factors you may not have known are now here for you to see. One of the things that has lead the way f ...

    ... carbon dioxide plus carbonic acid. The carbonic acid can neutralize hydroxide ions which if added, would increase the pH of the blood and cause alkalosis. The bicarbonate ion can neutralize hydrogen ions that, if added, would cause a decrease in the pH of the blood and lead to acidosis. Both changes in pH are life threatening. The carbon dioxide in the earth's atmosphere helps regulate the planet's temperature. When sunlight reaches the earth, some of it is converted into heat. The carbon dioxide absorbs some of the heat and so helps keep it near the earth's surface. If all the heat from the sunlight escaped into outer space, the earth would become very cold. The amount of carbon dioxid ...
