That might also keep the vapor from the solder condensing on the oven. I would be worried about using that oven for food in the future. Is apple lead free for it's solder?

Most likely. Everyone uses lead free for consumer goods that are also sold in Europe. It’s not worth the supply chain woes to be different. Despite what everyone says lead free isn’t all that bad.

  I learned on lead solder but quickly moved to lead-free and while there was a learning curve, I am confident that anyone capable of soldering leaded can be just as skilled with lead-free.

Everything these days should be lead free, but unfortunately that's just one of many toxic ingredients. I'd throw that oven out if I were him.

  There's no lead in the solder firstly, and secondly even if it was all leaded solder, it's not going to vaporize and deposit on the oven.

They might have antimony, bismuth, or cadmium. All are toxic. Also, many other components on the board could include God-knows-what. I'm not sure what Apple has or hasn't cut out of their stuff, but there's bound to be plenty of bad stuff left in there. I certainly wouldn't want to use that oven again.

Is there significant lead vapour pressure at a mere 200ish C?

  The vapour pressure of an absent element is approximately zero pascals.

  No.

The boiling point of lead is 1749°C. You're not going to get lead vapor from the solder at the temperatures of a toaster oven. The smoke is probably from some plastic component or some remaining flux on the board. But yeah, that oven shouldn't be used for food anymore.

  Liquid lead has a certain amount of vapor pressure even before it boils. Just like you can have water evaporate even when you're at temperatures below 100 C you can have lead enter the air even when you're below 1749 C.

    There is no leaded solder any more in consumer electronics. Even for leaded solder, the smoke comes from the flux core. You'll notice melting unfluxed leaded solder produces essentially no smoke.

    Solids also have a vapor pressure. Yes you've increased the vapor pressure, but you're way below the temperature where significant vapors are released.

Nobody really uses lead in electronics anymore unless it's absolutely necessary. RoHS (regulation concerning lead use in electronics in the EU) really worked. Lead-free solder has it's peculiarities but the industry long ago got used to it and leaded solder is now mostly seen by hobbyists. I've made the move to lead-free and while it's not quite as easy to work with, the peace of mind knowing I've eliminated at least one nasty heavy metal from my hobby is worth it.

The lack of lead in modern solder is what causes these issues in electronics in the first place. I remember it was a common discussion topic for the Nvidia 8800GT.

That's a myth. Leaded solder is completely safe for those soldering with it. You're never exposed to any lead fumes. Lead in solder is only a concern for the environment when the product is thrown away and that lead gets exposed to animal life. Apple products have been lead-free for more than a decade.
