Studies of the state of bottom soils of the city Desna river (Bryansk) were carried out as part of the recommended studies of state environmental monitoring. The purpose of the work is to identify the current state of the urban watercourse on the basis of ecological and analytical indicators of bottom soils for diagnosing the state of the surface waters of the Desna river. The study of the bottom sediments of the Desna river in the reference areas (cross-sections) showed that the content of heavy metals is within the normal range. The exception is the section of the river in the background region. The excess of concentrations for cobalt and chromium is 8.0 and 1.1 times from the established standards. The highest content of titanium oxide, chromium and cobalt was noted in samples on the right bank of the Desna river in the background area, which indicates that the area is silty. On average, the excess of chromium in spring was 7.5 times, and in summer - 8 times. For cobalt, the excess of the indicator compared to the maximum allowable amounted to 1.1 times throughout the entire spring-summer period. For the first time, the data of three-year studies on the state of bottom sediments are summarized, allowing the development of effective environmental programs and the creation of a constantly updated monitoring base.
