This dissertation examines the ecological dynamics of phytoplankton communities in the northern Adriatic Sea, focusing on phenology, environmental drivers, and trophodynamics. The complexity of the region, characterized by the richness of phytoplankton communities, environmental variability and intensive human activities, is not seen as an obstacle but as an opportunity to …

This dissertation aimed to explore the potential of Sr isotope ratio analysis, combined with multi-elemental profiling, as a tool for geographic discrimination, focusing on two projects: tracing the provenance of cheese/milk from Naxos, Greece (Project 1), and wood in the Eastern Carpathians, Romania (Project 2). The goal was to understand …

Mercury, a toxic element, known for its physical and chemical properties, spreads throughout the environment and is found in various ecosystems, including water, air, soil, and biological systems. The natural mercury cycle begins beneath the earth's crust, where it rises to the surface and is released into the air through …

In recent decades, hydrogen peroxide (H 2 O 2 ) has attracted considerable attention as a n omnipresent analyte, finding applications in clinical studies/diagnos is , biology, environmental protection, atmospheric studies, homeland security, and various analytical methodologies . This dissertation provides valuable insights into three different types of electrochemical sensors …

A paradigm shift is occurring in the assessment of exposure to urban environmental stressors. Improved accuracy of personal monitors has enabled researchers to study exposure at the individual level. Monitoring stations are the primary reference point for air quality in urban environments, although there is a need to assess exposure …

This thesis presents the simulation of approximated Gaussian process autoregressive models. Gaussian process models are a Bayesian nonparametric regression method, the main advantage of which is the quantification of uncertainty in closed-form. However, the closedform solution for the marginal likelihood results in a cubic computational complexity with respect to the …

Air pollution is an inevitable problem that modern society has to face today, with particulate matter (PM) being the most dangerous part of it, threatening human health and the environment. Not all PM particles, however, are equally harmful, since the dangerous potential depends on their size and chemical composition, which …

Atmospheric mercury (Hg) plays an important role in the biogeochemical Hg cycle. Hg species in the atmosphere are present in very low concentrations. While gaseous elemental mercury (GEM) is relatively inert, gaseous oxidized (GOM) and particulate-bound (PBM) mercury are highly reactive. These characteristics of atmospheric Hg species make the speciation …

Atmospheric pressure non-equilibrium plasma jets in material processing have received substantial attention in the past two decades and are still in the developing stage with a growing interest in material synthesis and surface processing. The main opportunities of these techniques are their potential cost reductions in apparatus and handling. Because …

In the present thesis, the problem of the functionalisation of fluoropolymers was addressed. As chemical methods for the functionalisation of fluoropolymers apply environmentally harmful chemicals, the research was directed to low-pressure non-equilibrium radiofrequency (RF) inductively coupled plasmas of environmentally friendly gasses. The research was focused on polytetrafluoroethylene (PTFE), the most …
