Contamination is the unwanted pollution of something by another substance. When a nuclear power plant leaks radiation into the atmosphere, for example, it causes a contamination of the surrounding area.

Contamination can also be used to refer to abstract ideas and concepts rather than to just physical things. The French complain that the increasing adoption of English words is a contamination of their linguistic heritage, and many parents today think rap music is a contamination of the public culture.
