When did air pollution became a thing?

Some would assign it to the start of agriculture 11,000 years ago, while others tie it to the advent of the nuclear era in 1945, but most recognize the Anthropocene as beginning with the industrial revolution (1780s-1830s).

Explanation:

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
