Air normally is a homogenous mixture as every type of gas has diffused to equilibrium, resulting in a thoroughly uniform mixture. So if you take air samples from 10 different places, you'll find the same ratios of all of the constituent gases.
If you include pollution with the city air, however, you'll normally be including non-gaseous particles as well. Other factors such as dust and pollen being taken into consideration also would result in a heterogenous mixture. Sometimes these factors are obviously unmixed (heterogenous) to the point that you can see different amounts of pollution or pollen.
