Document Summary
Smog and air pollution became problems in the beginning of the industrial revolution. 2 weeks of december 1952, london is known for humid air and during those 15 days, temperature was relatively low, humidity was high (80%), air was stagnant/still; cold weather and fog increased the demand for heating (coal burning) Huge amount of ash, particulate matter, and sulphuric acid was released in a short period of time by the burning of coal in still air (in addition to coal already being burnt by industries) About 4000 people died as a result of the air pollution/smog: the peak in the number of deaths coincided with the peak in both smoke and sulphur dioxide levels (as shown in slide figure) The crisis was solved by changing the climate; serves as a warning for other countries of the need to improve air quality. Southern on has many heavily polluted cities (hamilton, kitchener, etc)
