1.   The sickening stench of rotting rubbish rose into the air.

2.   The sickening stench of burned plastic permeated the air.

3.   A blue-and-white tractor chugs through the silted-choked streets, pulling a trailer with body bags and leaving a sickening stench.

4.   A pile of rotting garbage and a dead cow nearby gave off a sickening stench.

5.   A sickening stench permeated the whole scene.

6.   But the sickening stench of death still forces some to climb back atop the rubble, gagging and gasping for air.
