hemicals due to their characteristics. The results were necessary for the determination of the experimental programme concerning the investigation of the behaviour of these substances in the hydrosphereand in thesoiVwater in- terfare. These experiments procured clear imaginations about the transport behaviour of sink- ing and sunken chemicals. The results harmonized well with theoretical considerations espe- cially concerning the soil/chemical interaction and therefore were integrated into the 3D dispersion model of the BSH. Simltaneously the hydrod namic, geologic, and morphologic boundary conditions in those areas where accidents witi chemicals were likely to occur were investigated and compiled in hydrographic maps about control-relevent areas in the German part of the North Sea. Extreme difficulties occured in conjunction with the question of interfacial tensions between substance, sediment and water as well as with the solubility of chemicals under water. There exist deviating informations in the literature, and experimental verifications were not foreseen. 2 The studies concerning the "state-of-the-art" commenced in all areas as programmed and were terminated as planned in 1 Special attention was paid to the detection and identifi- cation of chemicals As there do not exist appropriate methods today there were no specifi- cations possible Another sub-programme concerned characteristics and rules forthe construction of chemical tankersand the determination of specificationsforthe construction of control vessels based on actual casualties and prevention strategies Simultaneously existing rules concerning the transport of dangerous goods at sea were com- piled and the basic presuppositions and technical possibilities of the recovery of released chemicals determined with respect to the transported bulks and the existing storage capacities on board of control vessels Furthermore methods and facilities were investigated and described which ar
