Dry wall is gypsum SULFATE

All drywall contains sulfur, in fact is sulfur. The unmentioned but all important question. Did the material meet ANSI and or ASTM standards? If yes, no foul. If no then what did the project specifications section 9 require? Did the drywall contractor comply? If yes, no foul.

I wonder if the issue is in natural gypsum wallboard
or some of that made from synthetic (FGD) gypsum...
None of the articles I have read seem to make any distinction.

"Dry wall is gypsum SULFATE All drywall contains sulfur, in fact is sulfur.

Sulfate is not sulfur. Sulfate is fully oxidized sulfur, S⁶⁺, and it's stable. The junk board sent over by the Chicoms is emitting sulfide, reduced sulfur(S^2-) as the gas H₂S. That gas is a neurotoxin and corrodes metals. It was probably generated by sulfate reducing bacteria when the Ca SO₄ was stored wet over there and on the way over. This junk board also seems to contain sulfides as a part of the matrix. That's uncommmon.

"Did the material meet ANSI and or ASTM standards?"

Do they have a stench spec?

I thought the Chinese ground up a lot of drywall and put it in dog food that they sold to Americans? ;)
