| Abstract: | Phenolics’ occurrence in surface water of the Dniester river basin (West Ukraine) with the definition of the natural background is studied. The main attention is given to the Upper Dniester basin and its tributary Stryj as the parts of the Sub-Carpathian oil- and gas province with the numerous objects of oil industry. The total amount of phenolics in water is studied. Phenolics’ concentrations from the first micrograms to the first milligrams per litre have been found in the surface water of the region. The natural background is defined as 0.012 mg l−1 for the areas out of the industrial influence. The anthropogenic part of phenolics is caused mainly by oil industry. The oil-producing objects provide the main phenolics’ releases in the region, due to the low protection level of mechanical facilities as well as to breach of technological norms on the oil-extracting objects. A man-made pollution of the basin water has a regional character and the natural self-purification processes seem to be insufficient for its neutralisation on the plains in particular. |
