Summary:The paper presents the results of assessment of the ecological state of bottom sediments in the Golden Horn Bay based on the integral index of pollution with heavy metals. According to the total pollution index, bottom sediments in major part of the show an average pollution level on Saet's scale. The most polluted are bottom sediments in the areas adjacent to whaf walls. A significant contribution to pollution of bottom sediments is made by copper, lead, cadmium and zinc. It was found that such substances as cadmium and lead did not enter the bay with wastewater in the period of 2011-2016, which indicates the accumulation of these pollutants in bottom sediments from wastewater that was entering the bay in an earlier period.
