Yes; air pollution is heterogeneous. Heterogeneous mixtures contain substances that are in different physical states. As well as poisonous gases such as SO2, polluted air contains particulates, such as soot from vehicle exhausts and dust from industries such as quarrying.

Answer:

Gaseous released into air eventually become diluted against the entire mass of air. At that time the concentration of these other gases would be too low to describe as pollution. At that time it would be heterogeneous.

When initially released air contaminants form a plume of higher concentrations which dissipates with distance travelled, mixing with the turbulence of the air, and the chemical half-life of the components. This non heterogeneous nature of air contaminants is the basis of many dispersion modelling programs available to environmental engineers.
