    Opis:
    Danger of pollution of water areas of the Sea of Azov and the Kerch Strait from possible technogenic catastrophes is diagnosed as a result of comparison of wind power calculations and the current state of coast of the gulf. Ideas of a uniform West Temryuk stream of deposits are disproved. Three dynamic systems in the east and in the center of a coastal arch and the unidirectional alongshore stream of pollutants and energy in the western segment of the Temryuk gulf are revealed.

    Opis:
    It is studied the distribution of Hg in bottom sediments of estuaries on the banks of the open water area of the Vistula Lagoon and in the Kaliningrad Sea Canal (KSC) isolated from it. Methods for the determination of Hg: inversive voltammetry and highly sensitive flameless atomic absorption spectrometry. It has been established: from spring to autumn the activation of storms and surge events in the lagoon, intensification of the water flushing regime of the channels ensure a significant Hg decrease in river mouths, but in dynamically weakened KSC conditions - an increase in Hg (from 0.05 to 0.85 mg / kg). In KSC bays, the safe level of Hg (0.3 mg / kg) for the period 2000-2015 was not exceeded (0.008 to 0.216 mg / kg), which indicates a favorable ecological and epidemiological situation. Hg determinations by low-sensitivity methods can be used only in qualitative assessments of the variability in concentrations of any dangerous toxicant. Finding a reliable amount of Hg in river mouths requires the use of highly sensitive methods of analysis.

    Opis:
    The forest conditions in the Central Aimag of Mongolia, located in the southern part of the Baikal catchment area, near the southern border of the forest-steppe subzone, were examined within the framework of this study. The field materials collected in the summer 201–2018 at the Zuunmod Model polygon serve as the core of the study. An ecosystem map of the Model polygon with the scale 1:50 000 and the Key plot with the scale 1:5 000 was drawn up using World Viеw-2 satellite imagery data (2016). The proven method of botanical indication of forest growth conditions is as follows: identification of the ecologic and coenotic groups of plant species, calculation of the moisture coefficient based on the ratio of the number of species included in the groups characterizing the extreme conditions of the moisture gradient and distribution of communities in accordance with the values of the gradient in the ecological series. Communities of stages of ecological series serve as indirect indicators of the forest conditions: Stage I: Кu <1, insufficient humifying for tree growth, Stage II: Кu 1–2, average humifying, Stage III: Кu >2, sufficient humifying for tree growth. The stages also correspond to the landscape conditions and the character of the vegetation cover.
