A substance that makes water, air, food, or another thing dirty, unsafe, or not pure.
사용 패턴：
a contaminant in [something]
자주 하는 실수：
Learners sometimes confuse 'contaminant' (a substance) with 'contamination' (the state of being dirty or unsafe) or 'contaminate' (the verb). For example, say 'The water contains a contaminant' (not 'The water contains a contamination') and 'The chemicals contaminate the river' (not 'The chemicals contaminant the river'). Learners also sometimes use it as an adjective, e.g. 'contaminant water'; instead say 'contaminated water' or 'water with contaminants'.
유의어
pollutant (Often used for substances that harm the environment, especially air and water; slightly more specific to pollution than 'contaminant'.)
|
impurity (More general and not always harmful; used when something is not perfectly pure, even if it is still safe.)
반의어
purifier (A device or substance that removes contaminants and makes something clean or pure, which is the opposite role of a contaminant.)
