    Soil entry pathways and quantities were evaluated for substances or groups of substances which had been classified as 'so far neglected'. This was done in connection with the German Federal Soil Protection Act and against the background of a precautionary soil protection. The aim of the project was to ensure that possible soil contamination sources would not go unnoticed and subsequently result in unpleasant surprises. The soil entry pathways of nine groups of substances were determined and their quantities were estimated. Production and consumption figures as well as results form environmental analyses formed the basis for this. In many cases a broad basis of data was available, facilitating a comparison of different entries and of entry quantities with background values. In these cases entries were classified as either relevant or negligible. For some groups the data basis was insufficient and further investigation is required before an assessment will be possible. The available literature dealing with the terrestrial ecotoxicity of the substances and groups of substances has been reviewed. Unfortunately, it facilitated a comprehensive hazard assessment with regard to soil functions only in very few cases. There is considerable need for research in this area. At the end of the project a professional discussion with experts from industry, universities, and administration was held at which the results of the investigation were discussed and supplemented. The experts seconded the conclusions drawn in the report.
