[Stoves] fate of emissions over time

[Huck Rorick]

Can anyone tell me briefly or direct me to more information on what happens
with emissions other than CO2 over time?  E.g. CO, methane, PM2.5?  People
can breathe these in directly from the fire or indoor space.  Once they
enter the atmosphere what happens?  Do they go into the upper atmosphere,
evenly distributed, stay low?  Does PM2.5 precipitate?  I understand that
methane doesn't last so long as CO2.  What happens with CO?  I would be
grateful for a brief overview.

Thanks,

Huck
