, Establishing such an exact survival time is impossible, because different people have different responses. But we can ballpark it and get a rough idea of how bad it is.First planet:
The biggest offender is the SO2 at 0.0027atm partial pressure. That's equivalent to 2700 ppm concentration at Earth surface pressure, and is 27 times greater than the level considered "immediately dangerous to life and health", with death possible within an hour. Few cases of acute exposure at concentrations this large have been studied in which the concentrations were known. But I think it is safe to say that your demise due to exposure on this planet would be fast and also very unpleasant.
Ignoring the SO2, the next greatest issue is the low partial pressure of O2. At 0.09atm, this is like being at about 7000m (23000ft) altitude on Earth, which requires a long period of acclimatization. Being immediately introduced to this oxygen concentration would cause you to pass out within about 5 minutes. Even with
acclimatization, most suffer effects of high altitude sickness, and their health may slowly deteriorate. Some deteriorate or even die quite suddenly; victims of HAPE
The oxygen pressure on this world is well within the breathable range. But what is definitely not in the breathable range is the CO2. At 0.29atm, this will kill you in minutes. So will the SO2.
