Abstract from the publication of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety of Germany:
In its final report, “Critical evaluation of the establishment and implementation of indoor limit values in the EU” (INDEX project), the EU commission classifies formaldehyde in group 1 “High priority”.
This makes formaldehyde one of the most dangerous substances in indoor air – together with benzene, acetaldehyde, carbon monoxide and nitrogen oxide.
