Is tin foil poisonous when heated at high temperature in oil?

Anyone who has eaten chicken wrapped in tin foil has seen it, and the tin foil used is not necessarily melted. Paper-wrapped chicken is pickled with chicken essence, wrapped with tin foil, and fried at 180℃ 10 minute.

It is certain that tin foil contains lead, which will be released when heated at high temperature in oil, but the amount is too small to reflect poisoning. But long-term accumulation is definitely bad for your health.
