The aim of this study was to obtain data about the contamination of different environmental compartments (102 surface water samples, 59 sediment samples and 165 eel samples) by polycyclic musks (HHCB, AHTN, ADBI, AHMI, and ATII) within the framework of an exposure monitoring program. Results for HHCB (Galaxolide) gave the following mean values in areas strongly polluted with sewage: surface water 1.59 micrograms l-1; sediment 0.92 mg kg-1 d.w. and eel 1513 micrograms kg-1 f.w. (in the edible portion) (6471 micrograms kg-1 lipid). The following average concentrations were found in waters hardly contaminated with sewage: surface water 0.07 microgram l-1, sediment < 0.02 mg kg-1 and eel 52 micrograms kg-1 f.w. (445 micrograms kg-1 lipid). Mean concentrations of 6.85 micrograms l-1 (maximum: 13.3 micrograms/l) could be measured at sewage treatment plants' outlets. It could be shown that these polycyclics are highly suited to use as indicators of the degree of contamination of waters with organic substances originating from sewage. A mean bioconcentration factor (BCF) on wet weight of 862 (HHCB) and 1069 (AHTN) for the transfer from water to eel under natural conditions could be calculated. The corresponding BCF-values based on the lipid content of eel were 3504 (HHCB) and 5017 (AHTN).
OBJECTIVES: Social cohesion is recognized as a fundamental condition for healthy populations, but social cohesion itself arises from political unity. The history of the Berlin Wall provides a unique opportunity to examine the effects of partition on social cohesion and, by inference, on health. METHODS: This ethnographic study consisted of examination of the territory formerly occupied by the Wall, formal and informal interviews with Berlin residents, and collection of cultural documents related to the Wall. Transcripts, field notes, and documents were examined by means of a keyword-in-context analysis. RESULTS: The separation of Berlin into 2 parts was a traumatic experience for the city's residents. After partition, East and West Germany had divergent social, cultural, and political experiences and gradually grew apart. CONCLUSIONS: The demolition of the Wall--the symbol and the instrument of partition--makes possible but does not ensure the reintegration of 2 populations that were separated for 40 years. The evolution of a new common culture might be accelerated by active attempts at cultural and social exchange.
