The aim of this work was to study the distribution of gross forms of elements - Ca, Mg, Sr, Ni, Cr, Zn, Mn, Cu, Fe, Pb, Cd, Co, As in the soil and plants of roadside agrocenosis. Agrocenosis Triticum aestivum L. is located along the Federal highway P-404. Sonchus arvensis L. and Cirsium setosum (Willd) Bess. are dominant weed species of agrocenosis, have a similar elemental composition. Phytomass of these plants does not accumulate As, Cd, Co, Ni, Cr, Zn, Cu, Mn, Pb. The content of Ca, Mg, Sr, Fe does not depend on the removal of the roadbed. Triticum aestivum L. - the main crop of agrocenosis, does not accumulate in its phytomass As, Cd, Co, Ni, Cr, Zn. The concentrations of Ca, Mg, Sr, Mn, Cu, Fe, Pb in the phytomass of Triticum aestivum L. are not dependent on the location of the road and are in the same range over the entire area of the field. The approach to the roadbed at a distance of 15-200 m did not affect the salt composition of the soil; the pH of soil samples taken over the entire field area is neutral. As, Cd, Co in soil are not detected. The value of the gross forms of Cr, Cu, Sr, Zn, Fe in soil does not exceed the value of their clarkes in the lithosphere. The content of gross forms of Pb and Mn in soil does not exceed the maximum allowable concentration. The approach of the road did not have a critical impact on the elemental composition in the components of the roadside agrocenosis.

The article presents the results of hydrological calculations for small watercourses located in the Slavsk district of the Kaliningrad region. This territory is of considerable interest, as it contains the largest array of polder lands in the region. At certain periods, systematic observations of the hydrological characteristics of some water bodies were carried out on the studied territory: Zlaya river - Krasnoznamenskoye village, Osa river - Priozerye village, Nemoninka river - Timiryazevo village; currently there is only one hydrological post. In this work, taking into account the requirements of regulatory documents, the choice of analogous rivers is justified: for Zlaya river - Instruch river, for Osa and Nemoninka rivers - Zlaya River. According to the data of hydrological observations and the restored values, theoretical probability curves of average annual discharge of the studied rivers are constructed and the values of average annual discharge of various probability are determined. The data obtained can be used in the performance of engineering surveys, the development of measures aimed at the sustainable functioning of water management systems, the determination of ecological runoff.

The article discusses the ice formations of small rivers in the upper reaches of the Irkut river basin. Morphometric and morphological characteristics of icings were obtained, the map-scheme of ice formations was created and analyzed, features of icing processes and their influence on the relief of small rivers were identified using data of field research for 2021-2022, analysis of cartographic material and satellite images. It has been established that the longest and gentlest icings are confined to the area of the Munku-Sardyk massif, the steepest icings - to the Nuhu-Daban and Tunkinsky Goltsy mountains, the icing coefficients of the rivers vary from low to medium values. The main role of ice formations is to transform the relief of the bottoms and slopes of small river valleys through erosive-accumulative (deep, lateral erosion and the formation of alluvial-iced terraces) and cryogenic processes (preparation of loose material).

The results of 10-year monitoring of heavy metals accumulation in the emission zone of technogenic pollution of Pervouralsk, Sverdlovsk region, are presented. The study was conducted on the gradients of pollution in pine plantations of the forest park and green zones of the city in order to study the accumulation of copper, lead, zinc ions in the soil profiles of sod-weakly podzolic soils. It was found that the bulk of metals accumulates in the litter and migrates down the profile in a small amount. Soil contamination by mobile forms of lead and zinc ions increased 2-4 times during the observation period. The study of the ratio of mobile forms of copper to its gross content in the soil showed that against the background of a significant increase in gross forms of copper up to 263%, the proportion of mobile forms is only 5-17%. A reliable correlation of soil acidity in the pH range of 3.97-5.71 with mobile forms of copper and zinc ions was revealed. The data obtained indicate that pollutants of hazard classes 1 and 2 have been removed from the migration flow and deposited by forest soils, which contributes to slowing down the pollution of the territory.

The article considers the results of the application of methods of correlation analysis of data decryption of satellite images, satellite data of the gravitational field, heat flux values and ground-based geological and geophysical data (geotectonic, seismological) measured in the region of the Pre-Caspian concentric depression. As a result, local concentric morphological structures with high values of gravity field and heat flow, promising for the search for new oil and gas fields, were identified in this and surrounding regions. From the constructed regional deep seismic sections across the entire territory of the Pre-Caspian concentric depression, the spatial location of a new presumably gas-prospective local ring morphological structure associated with a salt dome-shaped diaper-giant was revealed. A new hypothesis is also proposed, which makes it possible to explain, along with traditional hypotheses (gravitational, tectonic with tangential compression), how the processes of formation of salt diapirs can take place on the territory of the Pre-Caspian concentric depression.

In the settlement of Kez, as in other rural settlements of the Udmurt Republic, the main source of water supply is groundwater. The quality of groundwater does not fully comply with hygienic standards. In order to determine the probability of development of general toxic effects on the health of the population of Kez settlement when drinking groundwater was consumed, a procedure for assessing non-carcinogenic risk was carried out. The study showed that the greatest danger to public health are fluorine compounds in groundwater (the average value of the risk level for the territory was 0.97), as well as the content of sodium ion in water (the average risk level for the territory is 0.81). As for the total risk level for all considered components in groundwater, it should be noted that in 19 out of 25 wells the risk level is dangerous, while in 9 of them the risk level exceeds the upper permissible limit by more than 2 times.

The abnormally warm and dry summer was the main feature of the year 2021. The average temperature of June (21,4) was the record for the whole period of instrumental meteorological observations since 1752. The phenological anomalies were evident first of all in the early dates of phenostages of the year, since the third stage of subseason "Height of Spring" till the first stage of subseason "Abatement of Summer", and especially very early dates of subseason of "Full Summer", which became the record or close to record ones. So, the warming of the climate of Saint Petersburg is continuing and strengthening. In such condition after the winter 2020/21 the majority of trees and shrubs in Peter the Great Botanic Garden (Saint Petersburg, Russia) survived the winter without damages or with small damages not more than half of annual growth. The summer drought, accompanied by hot weather, caused the early yellowing and falling of leaves on many trees and shrubs which happened to be not hardy to drought. The phenological monitoring and timely publishing of results of observations is of important significance in conditions of climatic changes.
异常温暖干燥的夏季是2021年的主要特征。6月平均气温(21.4)是1752年以来仪器气象观测期间的最高记录。物候异常首先表现在从“盛春”子季第三期到“消夏”子季第一期的各表型期早期，特别是“盛夏”子季的极早期成为或接近历史记录。因此，圣彼得堡的气候变暖还在继续，而且还在加强。在2020/21年冬季过后的这种条件下，俄罗斯圣彼得堡彼得大帝植物园(Peter the Great Botanic Garden)的大多数树木和灌木都安然度过了冬季，没有受到损害，或者受到的损害不超过年生长量的一半。夏季的干旱，加上炎热的天气，导致许多不耐旱的乔灌木的叶子早黄、早落。在气候变化条件下进行物候监测和及时公布观测结果具有重要意义。

The article deals with the centers of action of the atmosphere of the Northern Hemisphere - the Icelandic and Aleutian lows, the Azores and Hawaiian highs, the Arctic and winter Asian anticyclones. The change in their characteristics in the annual course is considered. As such characteristics, the geographical coordinates of each center of action and the pressure in its center are taken. It is noted that the most mobile is the Arctic anticyclone. The winter Asian anticyclone practically does not change its position from month to month. The Icelandic Low is more mobile than the Azores High. The displacements of the Aleutian cyclone and the Hawaiian anticyclone are commensurate with each other. The winter Asian anticyclone affects the intensity of the centers of action of the atmosphere in the North Atlantic and the North Pacific. Before the appearance of the Asian winter anticyclone, pressure changes in the centers of the Atlantic and Pacific AAC occur in concert. During the formation of the winter Asian anticyclone, a mismatch occurs in the course of pressure in these centers of action. The degree of influence of the winter Asian anticyclone on pressure fluctuations in the centers of baric formations was made by the method of dispersion analysis. The degree of influence of the winter Asian anticyclone on the course of pressure in the centers of action of the North Atlantic atmosphere is estimated at 87%, in the centers of action of the Pacific Ocean - at 71 %.

The variability of air temperature is considered and an assessment of the bioclimatic conditions of the city of Kazan in the period 1966-2018 is carried out. Statistical processing of daily meteorological data for Kazan-Opornaya station revealed a steady increase in annual air temperature. An analysis of the dates of transition of the average daily air temperature (ADT) through the threshold temperature values (0, +5, +10°C) showed that in spring the arrival of the warm period occurs earlier, and in autumn it shifts to a later date and the duration of the growing season and the sum of positive temperatures increase. Temporal changes in effective and equivalent-effective temperatures, as well as the tourist index (TCI), repeat the course of air temperature, having the maximum variability in the cold period and insignificant in the warm one. According to the daily data of the tourist index in Kazan, the greatest number of days is represented by "unacceptable" climatic attractiveness and the least number - "ideal". The winter period (1966-2018) in Kazan is characterized by a weakening of the severity of winters, non-severe (mild) or slightly severe winters.
