Attacked from Inside What is the leading cause of death in the U.S.? Many people would guess cancer‚ but they would be wrong. The leading cause of death over the past few years has been heart disease. Last year‚ heart diseases claimed the lives of more than 600‚000 Americans. The most common of these is acute myocardial infarction‚ better known as a heart attack. Each year‚ about 720‚000 Americans suffer from a heart attack. That averages to almost two thousand heart attack cases a day! So why

The Prevalence of Asthma Associated with Air Pollution Air pollution is the initiation of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or damages the natural environment into the atmosphere. Air pollution occurs when the air contains gases‚ fumes‚ dust‚ or other harmful agents. According to Morgan (2003)‚ air pollution was not a problem until the 19th century and Industrial Revolution because pollution was readily

of internal combustion engine exhaust gas‚ particularly diesel exhaust. Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage‚ poisoning andpulmonary irritation caused by carbon monoxide‚ hydrogen cyanide and other combustion products. Smoke particles are an aerosol (or mist) of solid particles and liquid droplets that are close to the ideal range of sizes for Mie scattering of visible light. This effect has been likened to three-dimensional

Among the many types of air pollutants are nitrogen oxides‚ carbon monoxides‚ and organic compounds that can evaporate and enter the atmosphere. Air pollutants have sources that are both natural and human. Now‚ humans contribute substantially more to the air pollution problem. The effects of air pollution are diverse

carbon released each year about 3.3 Gt C accumulates in the atmosphere.” An increase of air pollutants is a result of continued use of fossil fuels. Air pollutants such as carbon monoxide‚ nitrogen oxides‚ sulfur oxides and hydrocarbons are produced as fossil fuels are used (Union of Concerned Scientist‚ n. d.). Carbon monoxide causes headaches and aggravates people with heart disease. Nitrogen dioxide and nitric oxides create smog‚ a yellowish-brown “cloud” layer that settles on the ground. And these

CASE STUDY 1: Xstrata Produced Acidic Oxide – SULFUR DIOXIDE Industrial Process – Sulfur Dioxide is an acidic oxide produced domestically and industrially in many ways. Xstrata‚ particularly Mount Isa Mines LTD‚ produces sulfur dioxide as a by-product from the extraction of copper from ores. Copper ore mined in Australia is predominantly chalcopyrite (CuFeS2)‚ a sulfide ore of copper. The extraction of copper begins with crushing the ore and subjecting the crushed ore to froth floatation. In
