Against the background of the global impact on the hydrosphere, there is a need to select priority indicators and methods for determining the environmental risk in case of pollution of river ecosystems. Newly arriving substances are involved in complex biogeochemical processes in the water column, migrate as part of suspensions, or settle to the bottom. During the freezing period, a special place is occupied by cryogenic biochemical processes occurring in ice. Microbiological studies of the Amur River near the city of Khabarovsk showed that the water quality diff ered signifi cantly in winter. In the under-ice water and ice sampled off the coast, a diff erent composition of organic matter (OM) has been recorded for many years. After the fl oods (2013, 2019), a high number of sulfate- reducing bacteria was recorded in individual ice layers, which aff ect the dynamics of the transformation of natural and anthropogenic substances. This is due to the fact that in the area of Khabarovsk, during the period of ice cover formation, humifi ed OM spreads along the left bank, coming from the Zeya and Bureya reservoirs during technological discharges of water and from the fl oodplain, and along the right bank – waters contaminated with OM, mainly anthropogenic character. Long-term studies of the potential activity of sulfate- reducing bacteria in the Amur and its channels (Amurskaya, Pemzenskaya) make it possible to predict the formation of hydrogen sulfi de zones and the likelihood of mercury methylation over a wide temperature range. The indicator of resistance of cryomicrobial communities to high concentrations of mercury can be used for a retrospective assessment of the environmental risk of mercury pollution of rivers during the freeze-up period.","PeriodicalId":408669,"journal":{"name":"Vladimir Ya.

The EPT index of indicator groups of mayfl ies (Ephemeroptera), stonefl ies (Plecoptera), and caddisfl ies (Trichoptera) in the streams of the Bolshaya, Kamchatka, and Avacha River Basins varied within 8–16, which corresponds to the standard of good-fair or fair water quality. However, given that the fauna of these indicator orders of aquatic insects in the Kamchatka Rivers is slightly more than 20 % of that in the south of the Far East; these regional features are also refl ected in the indices when assessing water quality, in particular, in the number of EPT species. And if the water quality is considered good if there are 24–31 species in the rivers of the south of the Far East, then for the watercourses of Kamchatka such water quality, which we assessed with an index of 10 to 16, is quite justifi ed. It is also necessary to take into account seasonal changes in the fauna, since the samples were taken in September, when most of the indicator taxa left the streams, and a number of species of the new generation had not yet hatched. Our results can be confi rmed by studies conducted earlier in the areas of existing economic facilities on the Kamchatka Peninsula, which showed that the EPT index in the background river sections varied from 10 (Agi R.) to 13 (Tolmacheva R.), which is comparable with our results.","PeriodicalId":408669,"journal":{"name":"Vladimir Ya.
