Name three historically important lethal pollution episodes. What role do epidemiologists have in preventing future incidents?

The first lethal pollution episode was in London in 1873-1963. It happens in the industrial revolution in 19th century Europe. During the industrial revolution, industries and households depend on coal for heating and cooking. Because of the burning of coal for heat , sulphur dioxide and other smoke were released during the winters. The emission of smog and sulphur dioxide persisted for several days and causing many people to suffer from respiratory problems and deaths. It causes most bronchial problems and killed about 500 people in 1873. In 1880, the sulphur dioxide released lasted for three days and killed more than 1000 people. In 1952, the "killer smog" created by the release of SO2 levels was so extensive that it made the fog turned black. The build up of pollutants combined with fog ...
