    Climate change and urban thermal stress: spatial-temporal analysis of bioclimatic comfort in Bursa, Türkiye
    (Springer, 2025) Canturk, U.; Koc, I.; Aricak, B.
    Climate change is reshaping global environmental dynamics, with profound implications for urban livability. This study evaluates long-term bioclimatic comfort shifts in Bursa, T & uuml;rkiye-a key industrial and agricultural region-using Discomfort Index (DI) and Effective Temperature-taking wind velocity (ETv) techniques under SSP2-4.5 (middle-of-the-road development) and SSP5-8.5 (fossil fuel-based development) scenarios (2022-2100). Model validation via AUC-ROC demonstrated robust accuracy for both indices (DI: 0.679-0.704; ETv: 0.602-0.654), confirming their reliability in projecting spatial-temporal changes. Results indicate a pronounced warming trend, with Bursa transitioning from cool to warm bioclimatic zones: by 2100, 62.9% (SSP2-4.5) to 69.1% (SSP5-8.5) of the province will shift into warmer comfort classes per DI, while ETv projects expanding very hot zones (8.5% under SSP5-8.5). Concurrent humidity declines (up to 4-6% reduction by 2100) will exacerbate thermal stress, particularly in urbanized areas. Projected changes will significantly increase cooling energy demands and public health risks, demanding urgent climate adaptation in urban planning. Our transferable methodology provides actionable insights for enhancing heat resilience and sustainable infrastructure in vulnerable Mediterranean cities. Overall, the findings emphasize the necessity of integrating thermal comfort concerns into regional development policies to mitigate escalating climate risks.

    Determination of heavy metal levels using Betulapendula Roth. under various soil contamination in Southern Urals, Russia
    (Springer, 2022) Isinkaralar, K.; Koc, I; Kuzmina, N. A.; Menshchikov, S. L.; Erdem, R.; Aricak, B.
    Heavy metals are hazardous to environmental and human health. Metals contained in the solid fraction of emissions are fixed in the soil absorbing complex and tend to bioaccumulate in plants, which can be used both to diagnose the level of contamination of forest biogeocenoses and to study the laws of the processes of absorption of contaminants in the soil-plant system. The research aims to determine the degree of pollution in Betula pendula Roth. from emissions from Combine Magnesite (magnesite ore processing and mining plant activity area in Russia) at 1, 3, 10, and 100 km far from the emission source, which experimental plots created in the 1980s. Soil samples were collected from these sites, and 1- and 2-year-old branches and leaf specimens were collected from B. pendula individuals. The lead (Pb), chromium (Cr), and iron (Fe) concentrations in soil and organs of B. pendula by the soil depth, washing, organ type, and organ age were determined. As a result, the variations in element concentrations by organs at all the distances and distances for all the organs were significant (p < 0.05). Metal concentrations were higher in the subsoil and leaf collected from 2-year-old branches. These results were interpreted as the higher values in the leaves of 2-year-old branches exposed to heavy metals in the air for a longer time, and the heavy metal concentrations in the subsoil increased due to the decomposition of these leaves. The movement of heavy metals, such as Pb and Cr, in soil was minimal.
