Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Unrecycled Sludge Cake Activated Sludge Water
525 wordsWhere does the wastewater go? When water goes down your sink or toilet, it travels through small pipes to much larger trunk sewers. The sewer systems are built to the slope of the ground around the Elbow and Bow Rivers. This slope allows most of the waste to go down by gravity, rather than expensive pumps, to one of four plants. To handle low areas, which do not have enough slope, pumping stations have been made. How is wastewater treated? Wastewater treatment in Calgary involves the following p...

Problems And Treatment Of Peptic Ulcer Disease
1,624 wordsPeptic ulcers are open sores or raw areas in the lining of the stomach (gastric ulcer) or upper part of the small intestine (duodenal ulcer). They result when the bacterium, Helicobacter pylori attaches itself to the lining of the stomach. Another cause of peptic ulcers are nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. The bacteria or NSAIDs weaken the protective mucus coating of the stomach and small intestines. This process allows acid to get through to the sensitive lining...

Symptoms Of Gas Gangrene Symptoms Of Gas Oxygen
811 wordsGas gangrene is a form of gangrene (tissue death) usually caused by a bacterium known as clostridium porringers, but many other bacteria can cause the same effects. It is caused by an infection of clostridium bacteria that, under low oxygen conditions, produce toxins that cause the tissue death and associated symptoms. Gas gangrene is rare, with only 1, 000 to 3, 000 cases occurring in the United States annually. Gas gangrene usually occurs at the site of trauma or a recent surgical wound. About...
