[Is it appropriate to consider wood preservative poisoning in the differential diagnosis of chronic recurrent respiratory tract infections?].

Wood preservatives as pentachlorophenol and lindane containing the highly toxic compound dioxin were common to be used to protect woods inside the house. In a case report a couple of symptoms are shown as upper airway irritation with dry mucosa, headaches, sleeplessness, lack of concentration and psychosomatic problems caused by those wood preservatives. The typical sequence of the symptoms is given. The results of blood and urine analysis on pentachlorophenol and lindane lead to investigations on indoor materials, air and dust. Taking out the contaminated materials is the best and only treatment.
