ok so I stumbled cross this becuse in n episode of ST:TNG (S3E01 "Evolution") there is mlfunction tht releses "nitrogen oxide" on the bridge nd everyone is coughing.

so I looked up different gses tht hve N nd O, none hve tht exct nme. noticed tht nitric oxide is pprently only produced when you brethe in through your nose:

Nasal breathing produces nitric oxide within the body, while oral breathing does not.

nywy the reference led to this rticle

    Nitrogen oxides is usually used to refer to pollutants produced by combustion, like in an engine or factory. It's written as NOx to represent both nitric oxide (NO) and nitrogen dioxide (NO2). Nitrogen oxides can exacerbate or cause asthma like symptoms when you breathe in higher levels.

    So I'm assuming that's what Mr. Picard was referring to
