Microelement determination in the underground water of the Romanian shore

This study is a part of a comprehensive research program on the Black Sea Romanian shore pollution. The experimental results for the trace element contents in the underground water and some surface water courses, located in south Dobrogea are given. The Instrumental Neutron Activation Analysis (INAA) and Inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP - AES) method have been used. Twenty elements have been determined, whose concentrations are below the maximum permissible values for drinking water. Mn, Ag, and Rb have not been evidenced. For two of the investigated surface water (Tatlageac and Albesti) the concentration of some microelements, exceeding the medium values in the underground water impose a special attention to be paid in the future. The underground water from the Mesozoic rocks has a smaller contact with the pollutant agents, compared to the Sarmatian one. (Author)
