Impact of vehicular traffic on the accumulation of metals by plants in the territory of Lviv

Visnyk of Lviv University. Biological series, 2020

The study was aimed at investigating the effect of traffic load on the accumulation of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) by moss gametophytes (Brachythecium rutabulum and Pylaisia polyantha) and aquatic macrophyte Lemna minor in the territory of the city of Lviv (Ukraine). In the course of the study, five sites were selected: site 1 in the territory of the Stryiskyi Park, which was used as a control one, and sites 2–5, in which the traffic intensity was analyzed and plant samples were collected. Sites 2 and 3 were selected in the middle and end parts of Stryiska Street, respectively, site 4 was located near the junction of Lychakivska and Pasichna streets, and site 5 was chosen in the immediate vicinity of Khortytska Street. Gametophytes of mosses B. rutabulum and P. polyantha were collected at sites 1–4 and analyzed for metals content; two ponds were selected at sites 2 and 5, respectively, and metal concentrations were analyzed in water and in the samples of L. mino...

Peculiarities of the Territory of the City of Lviv (Ukraine) and Their Influence on the Hydrological Regime and Erosion Processes

European vector of development of the modern scientific researches, 2021

The object of research is the territory of the city of Lviv (Ukraine). Lviv (geographical coordinates: 49N50, 24E00) is the largest city in Western Ukraine, with a population of over 720,000 inhabitants. The city is located in the western part of the Volyn-Podilska Upland, on the line of the Main European Ridge of the Baltic and Black Sea basins. Subject of research is relief parameters (maximum, average and minimum heights, vertical dismemberment and steepness of the surface) and land use characteristics (building intensity, phytocenotic cover). The purpose of research is to study the features of the territory of Lviv from the standpoint of influence on the hydrological regime and erosion processes. Methodology. Peculiarities of the territory of Lviv were studied by processing topographic maps using aerial photography materials and route surveys. Morphometric analysis of the relief was performed on topographic maps of scale 1: 10000 by dividing the map into elementary squares with ...

Soil-geographical zonation of Lviv oblast: structure and principles

Visnyk of the Lviv University. Series Geography, 2018

The scheme of soil-geographical zonation of Lviv oblast is developed on the principles of structural approach to the spatial organization of soil cover. Criteria for allocation of the ranked taxonomic units, their spatial and genetic properties are qualitative and genetic indicators of soil cover with the analysis of the spatial arrangement of soil combinations and structures. The following taxonomic units are identified in the proposed scheme of soil-geographical zonation: soil-geographic kraina (soil-geographic country), soil-bioclimatic zona/poias (soil-geographic zone/mountain belt), krai (region), okrug (county or mountainous soil region), rayon (district), masyv (massif). A mandatory criterion for all taxonomic units of soil-geographical zonation is the type of soil cover mesostructures (spatial-geometric characteristics of elemental soil areals and their spatial structures, as well as the dominated class of soil combinations). Two soil-geographic kraina (countries) are identi...
