Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct cognate 'поллютить' – it does not exist. Use 'загрязнять' for physical pollution. For figurative use, consider 'разлагать', 'осквернять', or 'портить' depending on context.
- Do not confuse with 'contaminate' (заражать) which has stronger medical/biological implications in Russian.
Common Mistakes
- Using 'pollute' for temporary or harmless dirt ('He polluted his shirt with mud' – use 'dirtied' or 'soiled').
- Incorrect preposition: 'pollute by' instead of 'pollute with' or 'polluted by' (passive).
- Overusing in figurative contexts where 'corrupt' or 'spoil' is more natural.

FAQ
Frequently Asked Questions
No. While its primary use is physical (air, water, land), it is commonly used figuratively to mean corrupting or spoiling abstract things like minds, culture, language, or a process (e.g., 'to pollute the scientific record with fraud').
They are often synonyms. 'Contaminate' is broader and can refer to making something impure by introducing a minor or major unwanted substance, including germs or radiation. 'Pollute' often implies a larger-scale, waste-related, environmentally harmful contamination and carries a stronger moral judgement. You 'contaminate' a sterile sample in a lab; you 'pollute' a river with industrial waste.
Almost never. 'Pollute' is inherently negative. If the effect is unintended or not harmful, words like 'mix', 'colour', or 'influence' are used instead.
The transitive verb structure [Subject] pollutes [Object] is most common (e.g., 'Smog pollutes the city'). The passive voice is also very frequent because the thing polluted is often the topic (e.g., 'The city is polluted by smog').
