ᐅ Considerations for Renovating the Roof Structure Regarding Old Wood Treatment

BounderHello everyone,
My question has the following background.
I have been converting the attic into a large living space (bedroom and second living room) for some time now.
Initial situation: uninsulated roof structure with old tiles. Floor made of old pine boards.
The roofer did the following:
Added exterior roof insulation with new roof tiles. I then installed counter battens from the inside myself and, due to the exterior insulation, directly attached the drywall panels. Some upright beams of the roof structure remain visible and are now to be sanded down.
By chance, I have now read that a wood preservative containing PCP and other harmful substances was used in the 1960s.
The beams, rafters, etc. have definitely been treated. They are brown compared to the untreated pine boards.
I now have serious concerns that I am exposing my family and myself to a significant health risk.
My question to you is: do you know if only harmful wood preservatives were used in the 1960s, or is there a chance that less harmful substances were also applied?
Second question, shouldn’t a knowledgeable roofer have noted this during an inspection?
I have attached a picture so you can see what I mean by the visible beams.
Regards
