At 50 km up only 7 ppm

Which as far as I can tell isn't terrible if you don't breath it in and if you do the official allowed exposure time is 10 minutes for 5 ppm. I would recommend you wear goggles in addition to breathing equipment, though.

Presumably that's 5ppm under terrestrial conditions, Venus at 40km has substantially higher pressure, more than is explained by the higher temperature alone, so any given ppm is a greater number of molecules per cm³, right?


7 ppm of atomized H2SO4 will definitely sting a bit. That's roughly 7 g/m^3, TLV for sulfuric acid mist is 1 mg/m^3. Survivable but you would want to minimize time in it.
