Answer:
The smaller the particle, the deeper it can embed in lungs.
Step-by-step explanation:
Pollution is a nasty thing and can affect us in so many ways. But one thing that is very bad is the small particles that get in our lungs.
The smaller the particle, the deeper it can embed in lungs, because it can find its way down to the smallest sections of the lungs, larger particles can't reach the smallest branches of our lungs.
Aerosol doesn't cause "ozone pollution", it can cause damage to the ozone layer protecting us all however.
