Contaminant

Contaminant denotes a substance that is either present in an environment where it does not belong or is present at levels that might cause harmful (adverse) health effects.

Any substance that enters a system (the environment, human body, food, etc.) where it is not normally found. Contaminants are usually referred to in a "negative" sense and include substances that spoil food, pollute the environment or cause other adverse effects.
