Pollutants 1950s single-family house massive construction

Hello dear forum,
we are currently in the process of buying a single-family house built in 1956. Unfortunately, back then many less healthy materials were often used. What do you have to look out for, what can be left as is? Asbestos is clear (but I rather don’t suspect it) and I have heard about parquet glue. Who inspects something like that?
Thanks in advance :)!

The adhesives were solvent-based well into the 80s. They were dangerous during processing, but harmless once cured, as were nitrocellulose lacquers. Wood preservatives like Xylamon are considerably more problematic in the long term. The popular Stragula floor coverings, however, are harmless early forms of vinyl. K.

Not so bad – twenty years later people considered it forward-looking to use "modern" materials quite naively. The late 70s to mid-80s are more of a peak period for health-critical materials, while the economic miracle era was much more restrained. "Asbestos" is almost a buzzword synonymous with all the fears of used house buyers. The wood preservatives of the aforementioned later era are much more common and concerning (they off-gas, which asbestos does not and is peaceful as long as it isn't disturbed).

Thank you, that already sounds good :)! Yes, I knew that asbestos itself does not have to be a problem. But perhaps one has to consider it during the renovation. Good to know that the parquet can also stay as it is. An acquaintance said that the adhesive permanently releases pollutants. Regarding wood preservatives, what is the best way to deal with them? Who tests the wood and what would one have to do if it is contaminated?

She is also right about that. Polyaromatic hydrocarbons are present in parquet adhesive, which was often used in the 50s and 60s. These can be, among other things, mutagenic and carcinogenic. As soon as the parquet becomes cracked and individual strips detach from the substrate, it becomes dangerous. By walking on it, the solid adhesive mass can be ground into dust and gradually penetrate through joints and cracks in this form.

Building biologists deal with this professionally. Such a person also clarifies which measures need to be taken.

Good to know, thank you! Then I will look for someone who can take a look at it with us as soon as possible.
