miasmal
Like poisonous vapors
Miasmal describes something relating to or resembling a miasma—a noxious atmosphere or unwholesome air once believed to cause disease.
The word appears in literary or archaic contexts to evoke foulness, corruption, or oppressive gloom: miasmal vapors rising from the swamp, the miasmal dread of the old house.
The variant miasmic is more common in modern usage.
