It is a suspension of dust particles in a mixture of gases. The latter may be considered a solution of other gases in nitrogen.
air is a solution
Air is neither a colloïd solution nor suspension. It is quite the opposite: a homogeneous mixture, like ALL gases do: there is only ONE existent gas phase .

seawater solution or suspension
I think the dust in air is neither a colloid, a suspension nor a solution. REASONS: 1. You can not say that it is a colloid because the common characteristic of a colloid is sticky like lotions and gels; 2. You can not say that it is a suspension because if it is, we should be able to identify easily the solid particles in the air which is the dust; 3. You can not say that it is a solution because it should form only liquid phase as result. Though I don't think is it is a colloid, a suspension, or a solution, I am sure that it is MIXTURE.
seawater solution or suspension
A mixture may be a solution, a suspension, etc.
suspension
Smoke is not a solution, it is a colloidal suspension of very fine particles in air.

A solution is a homogeneous liquid, a suspension is not homogeneous.
