    INVESTIGAȚII RECENTE PRIVIND STAREA RADIAȚIEI DE FOND ÎN ECOSISTEMUL URBAN BĂLȚI, REPUBLICA MOLDOVA
    (CEP USM, 2024) Stegărescu, Vasile; Ţugulea, Andrian; Bulimaga, Constantin; Bejan, Iurie
    This material reflects the study of the external gamma radiological fund level and the content of natural and man-made radionuclides in the soils of the Balti urban ecosystem in the Republic of Moldova. Radiometric and radiospectrometric research revealed values of the level of the external gamma dose rate as well as the content of anthropogenic and natural radionuclides (137Cs, 226Ra, 232Th, 40K) that do not exceed the provisions of the national norms (NFRP-2000). There is still a need to continuously monitor the level of the external gamma radiological background and the content of radionuclides of different origins in the soil and spontaneous flora, resulting from global deposits from nuclear tests and accidents, including from the Chernobyl NPP.

    IMPACTUL ACTIVITĂȚILOR ANTROPICE ASUPRA STĂRII DIVERSITĂȚII FLORISTICE DIN CADRUL ECOSISTEMULUI URBAN BĂLȚI, REPUBLICA MOLDOVA
    (CEP USM, 2024) Certan, Corina; Bulimaga, Constantin; Portarescu, Anastasiia; Grabco, Nadejda
    The ecological problems of the urban ecosystem require a complex study to highlight the paths of evolution in a global aspect. Contemporary urban ecosystems represent ecosystems with genesis and microevolutionary processes, it includes a varied spectrum of different taxonomic groups of plant and animal organisms, which occupy certain ecological niches in the ecosystem. The research was carried out in the field during the vegetation period (may – september) of the years 2020 – 2023. The evaluation of the state of floristic diversity was carried out by the method of linear transects. In order to ensure the sustainable development of the plant component of the Balti urban ecosystem, it is proposed to plant species of trees and shrubs that prevent soil erosion, mitigate noise pollution, have the ability to absorb carbon dioxide, retain solid particles from the air, can serve as of habitats for urban fauna and can be used as bioindicators of environmental quality.
