Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
A polluted water may be a homogeneous or a heterogeneous mixture.

A polluted water may be a homogeneous or a heterogeneous mixture.
Air is a mixture of several gases, most notably nitrogen, oxygen, and some trace gases (eg, argon).
A homogeneous mixture is when particles of one substance are evenly mixed with the particles of another substance. This results in a uniform composition throughout the mixture, with no visible segregation of the components. Examples include salt dissolved in water or air.
An element - substance - NOT a mixture.
