Formaldehyde in parquet

The result of disturbances that have occurred to me, my husband and my baby of 9 months (red eyes, cough ...) I ran three tests for the detection of formaldehyde and all were positive (over normal limits).
I contacted the local health authorities that will air sampling for airborne formaldehyde and solvents, but will not analyze the floors. As the little girl crawls on the floor and you would like to pass some time, for my peace of mind, get it analyzed. I do not know how to do. Even the Harp has not given us a lot of information: they can analyze it to determine which substances are present but fail to tell me what percentage.
I ask you some advice on how to do these analyzes, and possibly also analyze the adhesive used for the installation, which contain the data-sheet is 4,4 '- Methylenediphenyl, but we do not know in what quantity. Thank you (R.G.)

cases of housing malaise after the laying of parquet are not new and in fact if there are fumes in the environment we need to analyze whether these come from products used for the installation or just the flooring.
In this situation it is useless to analyze the wood laid. If there is a possibility that the same has been polluted by the underlying products (adhesives and primers) you need to have different elements of the game rested and I think that in these situations the installer should work because the legal consequences could fall totally on him and would be extremely heavy.
In any case, who did the surgery had to first make a written proposal with attached safety data sheets so that the buyer could realize that the upstream intervention could lead to harmful or toxic or irritating fumes and then eventually had to work, by law, provide the client with the data sheet of all products and materials used by him in the intervention.
I consider it essential to insist with the ASL or the harp to make the measurements even at 30/40 cm from the surface and I usually, in these cases, I remove multiple items and I also analyze the load distribution layer attached with the adhesion layer to verify if this part of the substrate was impregnated by noxious substances because in this case the gravity is greater for those who live there.
