And mercury.

They mention high mercury levels as a trap or from wine that the emperor drank, but neither is likely (they often used to add lead to wine as a sweetener, but not mercury AFAIK). But, mercury contamination in tombs, especially in Asia, is very common from the heavy use of the deep red pigment cinnabar, also called vermillion, which is mercury sulfide.
They mention that they think rivers were recreated in the tomb using mercury.

That’s the story I’ve always heard. They use mercury to form rivers.

Their real concern is they’ll destroy thing.

The Terra cotta army was painted. The paint fell off once exposed to air.

I would absolutely think I just got cursed off I had opened the door to see that happen live

I was going to say “I doubt it was instantaneous”… but I stand corrected

"They suffered slow oxidation giving way to humid saturation due to groundwater seepage for 2,180 years, followed by rapid oxidation and dehydration in 1974 when the vaults were opened and exposed to the atmosphere. The color coating was severely damaged, then aged and peeled off…

Practically every warrior and horse was painted, but having been buried for more than 2,200 years the pigments were so old they began to change just 15 seconds after they were unearthed. Within four minutes the painting layers bound together by pigments became dehydrated, tilted and broke from the surface.”
