e available in Germany for the disposal of chemical/water and especially chemical/water/sediment mixtur- es which are expected by-products of the recovery of sunken hazardous substances Model tests were carried out in order to investigate into the fundamental presuppositions for the detection of chemicals under water as well as to test different means and measuresfor the control and recovery of sunken chemicals To avoid disadvantageous influences from breaking waves on the shipborne detection, identi- fication and recovery operations of sunken chemicals vertical wave absorber of short con- struction length was developed and tested For further optimization purposes the relevant arameters were separately varied and their influence on the absorption effect determined The result were basic approaches for the design of wave absorbers ~ ~ ~ ~ 2 Reduction of organic pollutant emissions 1 Many halogenated hydrocarbons (HHCs) and, in particular, many chlorofluoro- carbons (CFCs) have found widespread use in great variety of applications due to their outstanding technical properties, such as stability, non-toxicity, non-flammabil- ity, boiling point and, above all, their solvent power, especially on organiccontamina- tions. Some chlorinated hydrocarbons (CHCs) have high toxicological or carcino- genic potential and can pollute the atmosphere, soil and water if emitted. CFCs lead to depletion of the ozone layer in the stratosphere and contribute towards global warming of the Earths atmosphere (greenhouse effect). For example, some 3,0 HHCs were still consumed and largely discharged into the atmosphere in the old Federal Republic in 1. This total included about 9,0 CFCs. Solvents and cleaning agents While CFCs and CHCs proved successful as the technologically most suitable clean- ing agents in the past, the time has now come to develop alternative processes of at least equal quality. In this context, water-based cleaning processes are to predomi-
