Description 
Summary

The monitoring program was executed in order to obtain a first comprehensive report on the environmental aspects of dredging activities. The dredged materials are dumped into the Southern Bight of the North Sea. In order to evaluate the degree of contamination of the dredged sediment against the natural background levels, 77 samples of bottom sediment from the dredging areas, 3 samples of dredged material from the hopper or trailing suction dredger were taken. Furthermore, 10 bottom samples from the Belgian continental shelf outside the navigation channels were added.
