How does air pollution cause lung cancer


How does air pollution cause lung cancer?
Okay so I know that smoking destroys your cilia on your epithelial tissue. So knowing that can you give me a detailed explanation of how air pollution causes lung cancer. For example: Air pollution causes lung cancer because the particles are trapped iin the lung and become infected with cancer. Now I know that isnt the answer. Thanks soooo much for your help.
