The report provides a quality-assured database for the technosphere compartment as part of the further development of the POP/dioxin database into a knowledge-based system that can be used as a flexible evaluation instrument. To this end the existing database inventory of technosphere samples was classified according to primary and secondary sources with further subclassification in a tree structure. New data were added and existing data amended in order to raise the overall data quality in the database. To facilitate recognition of typical patterns in the data and comparison of samples according to their contamination profile R programs for cluster analysis were developed and applied.
