Honestly don’t worry, as Mythbusters pointed out that neither are a health concern due to the low concentration relatively speaking and if anything it helps your immune system build up defenses against E coli and the like. Just know lid up during your flush means the sent lingers less. Then after the flush I would advise closing the lid to keep any lingering sent in the air of the toilet bowl and less likely to be disturbed by any airflow in the room. Just don’t like seeing misleading info spread around as honestly the science behind it is pretty interesting.
