"Tamten gaz ma silny zapach."

Translation: That gas has a strong smell.

"That gas smells strongly" Or is that too far from the Polish sentence?

[Jellei]

"silnie pachnie".

[Walkinthedog]

My first guess was odor.

[Jellei]

"odor" works.

Well, technically "zapach" is neutral in meaning, but somehow it seems safe to assume that this smell here is unpleasant.

Przepraszam, nie powinienem był jeść tych dwóch burrito z fasolą.

[Polyglot_Hanka]

Could "mocny" work here instead of "silny"?

[Jellei]

Yes, I guess so. Added.

[chce_polski]

People can smell when you Taco Bell

[losik55]

What about aroma.

[JerryMcCarthy99]

"aroma" is a nice food or coffee smell. I don't think it really applies to a strong gas smell.
