Is this pressure-treated? What to do?

[Lunda123]

Hello, I'm in the process of laying a new floor.
There was previously some plastic flooring in the kitchen.

In connection with this, I see that some joists are green.

Possibly pressure-treated??
I don't smell anything either now or when
we bought it 1 year ago.

What would you do? The kitchen, by the way, is from the 60s-70s.
There is yellow mineral wool insulation between the beams.

I really don't have the energy/time/money to tear up the whole floor

Pressure-treated or perhaps more likely cuprinol-treated. Put some of the floor insulation in a plastic bag, tie it up and take a long walk. When you get home, stick your nose in the plastic bag before going inside. If it smells musty, then it is the impregnation agent.

What is under the floor/joists?

The worst is pressure-treated joists cast in a concrete slab.
It also looks more like they were brushed with Cuprinol.

What is under the floor/beams?

The worst is of course pressure-treated beams embedded in a concrete slab.
I also think it looks more like they have been brushed with Cuprinol.

It's a small crawl space, so it's in the "air" and ventilated underneath.

As long as it is dry, chlorophenol (which was included in Cuprinol green and old pressure-treated wood) does not give off an odor, right? So perhaps it's easiest to leave it as it is if you're not experiencing any issues?
