Asbestos: Behavior, Dust samples, Material samples

Sure, those were all people who can earn money.... Therefore, I am of course also making inquiries here in parallel and naturally hope for well-founded opinions or assessments. I am quite aware that the person who can make money from it also wants to sell their product... Therefore, I am naturally suspicious and unfortunately there are no reputable contact points to trust. (or do you know one?) Why I want to investigate at all is the concern that something could still be in the air or stirred up and that for already 4 years, which is driving me crazy. Not a nice thought ... and of course even worse if you are expecting a child... And since I am an amateur and have no background knowledge about asbestos and you only ever read some kind of horror stories on Google, in the end you don’t even know how to properly assess the matter. For example, a building biologist holds the view that fibers could be continually released upwards when walking on the parquet...(all in the subjunctive) The gap is even sealed with acrylic.... The costs for measurements are immense (quickly 200 euros per room without travel without working time. That quickly adds up to total costs of 2,000 euros!).... Annoying situation!

Asbestos fibers are virtually everywhere in the air, especially in large cities. I consider the danger situation here to be very theoretical and contrived.

So, money-making to some extent?

A building biologist represents, for example, the view that fibers could permanently come up when walking on the parquet...(all in the subjunctive) Meanwhile, the gap is even sealed with acrylic....

Well, HOW could that be, if the parquet is sealed and has an acrylic expansion joint or baseboards around it.
Possibly the parquet is even glued down, then even less than nothing happens there.
Don’t let yourself get crazy, IF there WAS asbestos in one of the floor coverings, then it is now gone with the covering.

Many thanks for all your contributions and your patience!! I have now removed another piece of molding. The joint is foamed. It will probably also seal?
And then one last question: in the kitchen, where the vinyl floor used to be, the parquet was only laid up to the kitchen cabinets and not underneath (construction botch!). That means the kitchen cabinets stand on a kind of wooden construction, underneath is the bare screed, possibly still some filler from the vinyl floor. So nothing sealed by parquet!! I hope this is understandable.
So there is no sealing here like in the other rooms where the parquet was laid up to the wall...

How should this be assessed? Thank you!

Again: a) according to the year of construction, there was MOST LIKELY NEVER ASBESTOS IN THE PLACE. b) Asbestos is primarily released during processing (cutting, sawing, sanding, etc.). So even if there is some kind of asbestos under your kitchen cabinets, everything is fine as long as you are not dancing the samba under the cabinets. Does anyone in the household have health problems? Why exactly are you so fixated on asbestos?
