Why inversions can cause an increase in pollution due to industrial development in a city?

Inversions can cause an increase in pollution through smog, which trap the pollutants produced by vehicles, fires and industrial activities in a city. The hydrocarbons and nitrogen oxides present in these trapped pollutants are transformed into harmful ozone by sunlight, resulting in reduced air quality. These gases remain suspended within the inversion layer causing a long-term impact on the global climate.
