| Abstract: | The equilibrium distribution of DDT between the liquid and solid phases in the sea water medium was investigated by means of the radiotracer technique. The investigation of the influence of DDT concentration on its adsorption on several solid phases is presented and results are given as adsorption isotherms. Desorption experiments indicate that these processes are reversible. Extension of desorption is higher from quartz than from limestone, while it is significantly lower than from marine sediments. Examination of the equilibrium distribution of DDT between sea water and the examined surfaces suggested that DDT in the investigated systems exists as a colloid dispersion. The results are also discussed from the point of view of marine pollution. Suggestions for the future work in this field are also given. |
