Document Summary
Case study#1- represents the landmark in air pollution. It is known as the london smog (1952). Winter of 1952 was colder than usual as a result, heating system was used more than usual. All heating systems at that time used coal coal with significant amount of sulfur. Another thing special during that period was that air was stagnant, no wind to push it away. The gases from coal accumulated in that air smog became so heavy that once a man guided a. People were choked by the sulfuric acid they started to cover their mouths because sulfur dioxide is soluble in water which was causing burning sensations in the throat. Besides heating, industrial areas were contributing to the air pollution as they also tend to use coal as their energy source. Heating plus industrial areas contributed to the huge amounts of sulfuric acid in the air which lead to think smoke. The reason probably is because environment was not saturated.
