prefabricated houses, although no longer the big trend in the construction industry, but still plays just the pollution from this type of house role. "In older prefabricated houses that were built until around 1990, it comes again and again that exercise the residents an unpleasant, sometimes even moldy, musty smell," says Ralf Holt, a director of BIOLYSA eV It came in part to health problems. Holt cites as examples of respiratory diseases and skin irritations. presumed
The usual cause behind the problem is, however, thought to be short. "A first suspected mold growth is usually not the cause." The reason for the discomfort lies rather in the materials used at that time.
prefabricated houses were and are made mostly of wood and wood products.
That in itself is positive, says the expert from Biolysa, but at that time was the wood has unfortunately been treated with harmful substances.
Until the 90s it would have been common practice to impregnate the wood with wood preservatives. Later it turned out that these are highly dangerous to health. Holt: "In particular, pentachlorophenol (PCP) and gamma-hexachlorocyclohexane (lindane) have in this Context are called. "
is even if the use of these chemicals remains highly restricted or even banned, one would find them as contaminated sites in the then built houses yet.
moreover, can outgas formaldehyde from particle boards also built, which is also known to trigger various health problems. According to Ralf
Holt, who lives as an expert and building biologist in Münsterland, tribe, the typical musty Done house smell "from the phenolic urea glues these structural panels:" These are formed only after several years by chemical reactions. "In addition to health while the everyday life of people disturbed. "Social isolation can be the result. - Children example, are often ridiculed by their peers and shunned, in extreme cases, no one wants more to do with the people"
is important in such a case an appropriate remediation strategy
