Abstract
Within the framework of a regional research programme in a harbour basin of Bremen, the regional distribution patterns of heavy metals, grain size fractions, Al, organic matter and Eh values were investigated. Due to regular distribution of nearly all the above parameters, it was possible to create maps of the patterns. The overall heterogeneous harbour sludge showed homogeneous areas in a scale of hundreds of metres. Additionally, the heavy metal contents of different grain size fractions were analysed in order to find out whether there are grain size fractions that can be used without further treatment. Heavy metal concentrations and their relation to standards, natural processes controlling heavy metal distribution patterns and aspects of practical relevance are discussed.
