Vertical and horizontal variability of volatile organic compounds in homes in Eastern Germany.

摘要: A German study on Indoor Factors and Genetics in Asthma (INGA) will be conducted for 10 years towns of Eastern Western Germany. The include an indoor outdoor exposure assessment BTEX (BTEX=benzene, toluene, ethyl benzene, ortho-xylene, meta- plus para-xylene) volatile organic compounds (VOCs). In a pilot study, which was Erfurt, city Germany, during the winter 1994, vertical horizontal variabilities concentrations within homes were examined detail. Passive sampling living room (at 0.7, 1.2, 2.0 m height), bedroom (2 m), kitchen outside window room, 20 randomly chosen adults. houses consisted ten old concrete constructions ('Altneubauten'=OLD, constructed between 1960 1970) new ('Neubauten'=NEW, 1970 1980). At each apartment, Organic Vapour Monitor (OVM) 3500 passive devices (3M Company) exposed 7 days. After elution with carbon disulfide (CS 2), samples analyzed dual column gas chromatography (GC) flame ionization detector (FID). No significant differences median values weekly average air VOCs different heights measurement rooms could detected. Kitchen equal both significantly higher than (except benzene). Significant OLD NEW buildings not detected toluene).
