How it's used

Focuses specifically on the visual presence of thick, dark, and often polluting smoke. It is frequently paired with 瘴氣 to form the idiom 烏煙瘴氣, which describes a place that is not only physically polluted but also chaotic, corrupt, or morally unpleasant.

Examples

Black smoke is pouring out from that factory over there.

Common phrases

foul atmosphere; chaotic and corrupt environment

Common mistake

Do not use this to describe steam or light mist, as it specifically implies soot or dark combustion byproducts. It is rarely used as a standalone noun in casual conversation without a descriptive verb or the extended idiom.
