    Their meanings are similar, but contamination can include harmless but unwanted mixing of two things - the milk carton split and the milk was contaminated by rainwater. It's not really harmful or injurious (rainwater is clean? Debatable, I know).

    Pollution implies contamination by a definitely harmful substance.
    Air polluted by smog, or a lake polluted by chemicals. Definite harm results from pollution, whereas it has not necessarily to from contamination (of course it can, say in radioactive contamination).
