First time (I think) posting here. Apologies if this has been posted before.
Curious to hear everyone's thoughts on this.

Re: Toxic fumes
Seems to be prevalent problem, if you read any other av news site, with the A318-319/320/321.
Re: Toxic fumes
From the article:
It's interesting how CO detectors are so widespread in light GA, but not in jets where everybody breathes bleed air
A 2002 study mandated by Congress recommended requiring carbon monoxide sensors on all passenger airplanes. Today, most homes have them; airplanes do not.

mostly on iae engined aircraft interestingly enough

Carbon monoxide is a colourless and odourless gas, that is a by product of combustion. What was described in the article was visible and had a smell, so it is not carbon monoxide.
It’s widespread in GA because they heat the cabin by taking air from around the exhaust downstream of combustion where carbon monoxide is a by product of combustion. Bleed air from jet engines is taken from the compressor upstream of combustion.
Lawmakers advocating carbon monoxide detectors in an airliner is like lawmakers advocating injecting disinfectant for COVID. It is not their area of expertise.
Re: Toxic fumes
If there is a failure of one (or more) of the seals in the compressor, there is the possibility of oil getting into the bleed air system. This, in turn, travels to the air conditioning packs and the heat within the ACM/heat exchangers can cause smoke. This smoke is very acrid although I can't say if it contains CO (Carbon Monoxide) or not. Even without CO, I doubt it's good for your health. I know it makes the air in the cabin hard to breathe and will set off the smoke alarms in the lav.
Having said all that, Zeke is correct that you would not need a CO detector to know this is present, you smell it and feel it burning your eyes.

One of the big events discussed in this article was on a US 767 flown STT-CLT. That flight ended up being the last flight Capt. David Hill and his crew flew. Their medicals were revoked, and Capt. Hill ultimately fell into a deep depression and committed suicide after pleading for regulators to do something.
If i'm remembering correctly, the pilots had no idea that a fume event was even occurring until the flight attendants noted they both had completely bloodshot eyes when they landed.

Significant difference, though, is that CO detector cannot harm anyone (unlike instant harm with desinfectant) - not until there is an actual problem. It may be a cost (oh, certification); but those detectors are generally small and lightweight. There may or may not be very useful, but that is a different story
Re: Toxic fumes
I remember this issue was in the press in the local Seattle papers a few decades ago related to Alaska Airlines crew and fume events on the MD80 series.
Here is something from the Seattle Times archives:
