In the Great Smog of 1952 in London, it is estimated that around 12,000 people died prematurely due to the effects of the smog. The exact number of deaths directly caused by the smog is difficult to determine, as many deaths were attributed to respiratory issues exacerbated by the pollution.
The duration of smog events can vary significantly depending on the specific incident and location. For example, the Great Smog of London in December 1952 lasted about five days, while other smog occurrences may last from a few hours to several days. Factors such as weather conditions, pollution sources, and geographic features all influence how long smog persists.
smog = Smoke + fog it is created when the fog mixes with the pollution in air. Smog looks almost like fog, but is harmful if inhaled for a sufficient period of time.
The "short" answer is- Inefficient combustion in the vehicle's engine produces chemicals that when exposed to sun-light create smog.
