NORTH SOUTH UNIVERSITY Project on Air Pollution BIO-103.3 Summer 2013 Prepared for: Dr. S.M. Mostafa Kamal Khan (SKK) Introduction to Pollution: What is Pollution? Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Air Pollution:

Another disappearance that leaves researchers speechless is that of the USS Marine Sulfur Queen. The tanker left Beaumont‚ Texas headed towards Norfolk‚ Virginia. ON February 3‚ 1963 the ship radioed her position‚ which placed her near Key West in the Florida Straits. Three Days later‚ all that was found from the sip was a solitary

hydrothermal eruptions. The east rim of the crater had a large number of fumaroles-hot gas vents that release a combination of water vapor‚ CO2‚ hydrogen sulfide‚ CO‚ and methane. The temperatures range from 75-95 degrees Celsius and they also deposit sulfur and gypsum crystals. The fourth point was the highest point of Nea Kameni at 127 meters. The peak is known as Georgis dome and was formed during the 1866-1870 eruptions. There was an amazing view of the caldera and amazing surrounding islands.

The characteristic symptoms of a scabies infection include intense itching and superficial burrows.[4] The burrow tracks are often linear‚ to the point that a neat "line" of four or more closely placed and equally developed mosquito-like "bites" is almost diagnostic of the disease. Itching [edit] In the classic scenario‚ the itch is made worse by warmth and is usually experienced as being worse at night‚ possibly because there are fewer distractions.[4] As a symptom‚ it is less common in the elderly

health problems that can be contributed to our environment. (Godish) One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The exhaust from a factory includes‚ sulfur oxides‚ nitrogen oxides‚ carbon monoxide and dioxide‚ as well as volatile organic compounds and particulates. There is not an area of the Earth’s atmosphere or an ecosystem that has not been altered by the long term effects of the pollution created

a variety of different compounds and by products. Another important property of magnesium is that it actively reacts with many non-metals such as nitrogen‚ phosphorous‚ chlorine‚ sulfur‚ bromine‚ iodine and fluorine. Magnesium also readily reacts with some other compounds such as carbon monoxide‚ carbon dioxide‚ sulfur dioxide and nitric oxide. Magnesium has an appearance of a silvery and white shade. Among all the structural metals‚ magnesium is the lightest. The structural metals are generally

will help increase the rate of growth of the barley because plants take in carbon dioxide for photosynthesis. The ingredients of Tonic Water are macronutrients for plants to grow. These include carbon dioxide‚ oxygen‚ hydrogen‚ phosphorus‚ sodium‚ sulfur‚ and potassium. The tonic water should also help increase the rate of production because it contains macronutrients that are helpful to the growth of plants. In addition to testing Tonic Water‚ we are adding one tablespoon of sugar to the water.
