Schwer flüchtige organische Umweltchemikalien in Hamburger Hausstäuben

From 1998 to 2000, Hamburg environmental protection authority conducted a survey on 58 non-volatile organics in dust from vacuum cleaner dust bags taken from 65 apartments. Chlorinated paraffins and organotin compounds were determined for the first time in indoor dust matrix. 95-percentiles like 1600 mg/kg for Bis(2-ethylhexyl) phthalate (DEHP), 180 mg/kg for Dibutyl phthalate (DBP), 180 mg/kg for short-chain chlorinated paraffins, 110 mg/kg for Permethrin, 8.7 mg/kg for Monobutyltin, 6.2 mg/kg for Tris(2-chloroethyl) phosphate (TCEP), and 1.1 mg/kg for Benzo[a]pyren were found. Based on questionnaire data regarding the use and/or the presence of certain products in the examined apartments an evaluation procedure is proposed, indicating probable sources of certain non-volatile organic compounds. Some of these may be carpeting made from wool as a probable source of the biocide Permethrin, and floorboards as a probable source of the formerly used biocide DDT, outlawed since 1972.
