Concentrations of oil in the water of Ukrainian Section of the river Danube between 0 and 0,30
mg/L with average concentrations 0,08 - 0,11mg/L (data of the State Committee on
Hydrometeorology). According to existing assessment criteria the oil polluted water (more than
0,05 mg/L) are not acceptable for fish reproduction when pollution events occur regularly.
Phenol pollution is much more serious because the minimal concentrations of these compounds are
equal or higher than maximum allowable concentrations for fisheries and sanitary-hygienic uses.
Seasonal variations of phenol contents (See Fig. 4.20.) are not significant with small peaks during
spring and summer flood events. As can be seen on the Fig. 4.20. big share of phenol pollution is
released from the territory of Ukraine at the section between Reni and Vilkove.
