The atmosphere was stuffy, laden with a heavy smoky odor.

The heavy odour of stale fish and musk on the warm air.

Under standard conditions, it exists in the form of white crystals with a heavy, sweet odor.

The heavy odor of rancid oil hung in the dank air.

But he had never thought of lamb as a heavy odor.

He could smell the oil, a heavy odor.

The beautiful old church was rank with the heavy odor of rats.

There was a heavy odor of mushrooms all around.

The heavy odor of incense seemed to cling about its pages and to trouble the brain.

And then he was suddenly aware of a sickish, heavy odor in the chamber.
