Aspects on the Accumulation of Trace Metals in Various Environmental Matrices (Water, Soil, Plant and Sediments): Case Study on Catchment Area of the Somes River, Romania

A study was carried out to determine the accumulation of trace metals in water, sediments, and soil from several locations in the Transylvania region (Romania), using the inductively coupled plasma mass spectrometry (ICP‐MS) technique. A significant number of metals (range of several μg L−1) were identified, the toxic metal concentrations in mostly of the investigated waters being within the permissible limits. A seasonal variation in the metal content was also observed. Comparison of the metal concentrations to samples of sediment, soil, and vegetation coming from the surrounding areas of the same water reservoir revealed a higher accumulation of rare and toxic metals in sediments than in soil and vegetation

Romania\u27s Participation to the European Assessment Project Titled HyUnder, Multi-Criterial Analyses of Salt Cavern Locations

The scope of the work is to assess the potential, the actors and relevant business cases for large scale storage of renewable electricity by hydrogen underground storage in Romania. This presentation intends to provide a picture of the multi-criterial analyses of salt cavern locations in Romania. The energy sector is facing with the necessity to store large energy quantities for short to long term in order to adapt to the increasingly intermittent renewable energy. The results of this presentation have originated from an ongoing European assessment project by the name of HyUnder (FCH JU, grant 303417) regarding utilization of salt caverns for hydrogen underground storage. Currently, main uses of salt caverns include storage of hydrocarbons or wastes disposal. Salt caverns have stirred the interest of the scientific community regarding the potential applications in hydrogen economy. Romania has active mines or caverns and others closed, many of them have the potential to be used from hydrogen storage. These facts represent an interested situation in order to initiate studies or assessments of the potential hydrogen underground storage. The salt mines, hydrogen producers, renewable energy sources and research centers with high qualified scientists, represent essentially elements for new type of studies regarding hydrogen economy. In the context of scientific community\u27s efforts from Romania to assert active in the area of hydrogen technologies, this approach can certainly constitutes an attractive example for pan-European cooperation. The work disclaims the technic multi-criterial analyses of salt cavern locations regarding hydrogen underground storage. The introduction of hydrogen into economy offers the possibility to provide a number of advantages: sustainable development, valorization of local resources and improvement of competitiveness. The opportunities and viabilities of salt cavern locations are analyzed

Challenges of anticoagulant treatment in atrial fibrillation with liver disease

Managing anticoagulation therapy in individuals with atrial fibrillation who also have liver disease is highly challenging due to altered blood clotting processes and the risk of bleeding due to liver dysfunction. The literature highlights the complex nature of anticoagulant therapy in these patients, emphasizing the need for personalized treatment methods that take into account both thrombosis and bleeding risks. Research has shown a higher occurrence of atrial fibrillation in people with cirrhosis, highlighting the need to find the best anticoagulation methods based on the severity of liver disease and patient-specific factors. The debate over the safety and effectiveness of direct oral anticoagulants compared to traditional drugs like warfarin in cirrhotic patients with atrial fibrillation is still ongoing. Collaborative initiatives between experts in hepatology and cardiology are needed to address the complicated interplay between liver disease and atrial fibrillation, promoting interdisciplinary care models that enhance patient safety and treatment effectiveness. By prioritizing a patient-centered approach guided by extensive research, future directions in the hemostatic management of cirrhotic patients with atrial fibrillation may improve clinical decision-making and therapeutic outcomes
