使い方のコツ

Pollution is usually uncountable, so avoid saying 'a pollution' or 'pollutions'. To be more specific, use phrases like air pollution, noise pollution, or water pollution. Also, don't mix up the noun 'pollution' with the adjective 'polluted' (used for air, water, or places that have become dirty), as in 'The river is polluted.' In real sentences, pollution is often paired with verbs like cause, reduce, or prevent, so it helps to learn these together, as in 'cause pollution' or 'reduce pollution'.
