As a part of the German Environmental Surveys performed in 1985/86 (West Germany), 1990/91 (West Germany) and 1991/92 (East Germany), dust samples were collected in the households of about 1600 randomly selected adults (25 to 69 years) and an analysis of these samples was performed in respect of their content of 8 different @entity312 and of the synergist @entity33638 ( @entity20333 ). In the 1990-92 survey about 90% of the samples contained @entity315 in concentrations above the limit of quantification. This showed @entity315 to be the most widespread of the 8 compounds investigated. The geometric mean of the @entity315 content in domestic dust was 0.22 mg/kg. Only about 8% of the samples contained one or more of the other investigated substances ( @entity317 , @entity4204 , @entity5179 , @entity5179 , @entity316 , @entity70714 , @entity14869 ) in quantifiable amounts. About 76% of the samples contained quantifiable amounts of @entity20333 . In East Germany the geometric mean of the @entity20333 content (0.21 mg/kg) was significantly higher than in West Germany (0.07 mg/kg), but no difference for @entity315 was found. Significant associations could be shown for the @entity315 content and the application of biocides as well as for the @entity20333 content and regional factors (size of community, type of dwelling area). Samples collected in 1985/86 (West Germany) showed a geometric mean for @entity315 of 0.06 mg/kg and for @entity20333 of 0.07 mg/kg. Comparing the values of 1985/86 and 1990/91, a significant increase can be observed for @entity315 , whereas the @entity20333 concentration remained constant.
