    Impactul factorilor fizici interni și externi asupra concentrațiilor de radon interior ca problemă actuală a sistemului de sănătate în condițiile schimbărilor climatice regionale
    (CEP USM, 2024) Overcenco, Ala; Corețchi, Liuba
    Schimbările climatice pot intensifica migrația radonului în locuințe, ridicând riscul pentru sănătatea umană. Strategiile de eficiență energetică pot contribui la acumularea radonului în interior, în special în perioadele de iarnă și vară, când casele sunt închise pentru a menține echilibrul confortului termic. Studiile din diverse regiuni ale lumii arată, că factorii meteorologici influențează concentrația de radon în interior direct sau indirect. Colectarea datelor meteorologice simultan cu măsurătorile radonului interior, cu studiul relațiilor acestora, este esențială pentru înțelegerea acestor interacțiuni și dezvoltarea de strategii de sănătate publică privind prevenirea și adaptarea la clima viitoare. Pe baza experienței internaționale a fost elaborată metodologia de evaluare a influenței factorilor meteorologici asupra riscului de expunere la radon în aspect regional.

    ROLUL SPAȚIILOR VERZI URBANE ÎN ADAPTAREA LA SCHIMBĂRILE GLOBALE DE MEDIU
    (CEP USM, 2024) Ciubuc, Natalia; Cocin, Alexandru
    The role of urban green spaces in improving the quality of the urban environment and the cities adaptation to the climate changes was analyzed. An extensive bibliographic study was carried out, the contributions of green spaces in mitigating the effects of global environmental changes were evaluated, principles for the design of sustainable and resilient green spaces were highlighted and plant species capable of mitigating negative effects were recommended. As cities face the challenges of urbanization and climate change, investing in urban green spaces is becoming a strategic imperative. Cities that prioritize green infrastructure not only mitigate the adverse effects of global environmental change, but also promote resilient, vibrant and healthier urban environments for current and future generations.

    INFLUENȚA FACTORILOR FIZICI INTERNI ȘI EXTERNI ASUPRA RISCULUI EXPUNERII LA RADONUL REZIDENȚIAL ÎN CONDIȚIILE SCHIMBĂRILOR CLIMATICE
    (CEP USM, 2024) Overcenco, Ala; Coreţchi, Liuba
    The influence of internal and external physical factors on the risk of residential radon exposure under climate change. Climate change may intensify radon migration into homes, increasing health risks. Energy efficiency strategies may contribute to indoor radon accumulation, especially during winter and summer when homes are sealed to maintain thermal comfort balance. Studies from various regions of the world show that meteorological factors influence indoor radon concentration directly or indirectly. Collecting meteorological data simultaneously with indoor radon measurements and studying their relations is essential for understanding these interactions and developing strategies for prevention and adaptation of public health system to future climate. Based on international experience, the methodology for evaluating the influence of meteorological factors on the risk of exposure to radon in a regional aspect was developed.

    REVIEW OF THE RECENT FINDINGS ON THE ICHTHYOFAUNA OF THE PRUT RIVER, REPUBLIC OF MOLDOVA
    (CEP USM, 2024) Bulat, Dumitru; Bulat, Denis; Zubcov, Elena; Bileţchi, Lucia; Şaptefraţi, Nicolae; Ene, Antoaneta; Patriche, Neculai
    The investigations carried out in 2010-2022 in the Prut River basin within territorial limits of the Republic of Moldova revealed an ichthyofaunistic diversity consisting of 62 species from 13 orders and 22 families, of which 14 species are considered endemic to the Danube basin. A new species was identified in the Prut River in 2010 – Gymnocephalus baloni (Holcík & Hensel, 1974). Later, in 2015, the species Benthophilus nudus (Berg, 1898) was recorded for the first time in the Prut River, and in 2022 – Rutilus virgo (Heckel, 1852). The obvious biological progression of Gobiidae species in last decades is an alarming sign related to the stability of native ichthyocenoses. The analysis of the flow, spatial, trophic and reproductive preferences of fish denoted that most of species are eurytopic, benthic, omnivorous, lithophilous or phytophilous.
