Mercury is ubiquitous in the biosphere, occurring in the air, water, land, and soil, as well as in living organisms. Excessive exposure to mercury is associated with a wide range of adverse health effects including damage to the central nervous system and the kidneys. Mercury exists in many different forms in the environment which produce various patterns of toxicity. Protection of the food chain from contamination by mercury is an important task in the protection of health of the human population. The aim of the study was to monitor the concentrations of mercury in fish and fish products from food retail in Eastern Slovakia, and from the Ružín water reservoir, Košice district. A total of 384 samples of fish and fish products were collected for the study. Atomic absorption spectrometry standard solutions for mercury were used at a wavelength of 254 nm. The majority of countries and global organizations now enforce a maximum concentration of mercury in fish of approximately 0.5 mg.kg^-1. All of the 184 samples (50.52 % of the total fish samples studied) were above the maximum level set by the European Commission Regulation for mercury in fish. The systematic analytical control of contaminants in food is important. Mercury is concentrated in seafood, products of prey and marine fish, fish from rivers and lakes in the areas contaminated by mercury. According to the findings of this study with analyzer AMA 254, the consumption is not recommended of fish, especially seafood (meat of shark, swordfish and king mackerel), for selected groups of the population: children, women of childbearing age, pregnant women and nursing mothers.

Introduction: Mercury release in the environment is mainly the result of human activity, particularly from coal-fired power stations, residential heating systems, waste incinerators, and as a result of mining for mercury, gold and other metals, which have led to widespread global mercury...

Introduction and Objective: Contamination of soil by mercury poses several risks to human health through consumption of fruits and vegetables. In Slovakia, a high concentration of mercury is found in the soil of the Central Spiš region. The objective of the study is to measure the mercury...

Introduction and objective: Nomophobia (NMP) is a present-age phobia of loss of use of information and communication technologies (ICT), particularly smartphones. Material and methods: The study adopted a two-phase, exploratory consequential mixed methods design. The first phase was a...

Longstanding research suggests a plausible relation between physical activity, the natural environment, and overall health. However, when investigating this relationship, most studies focused on the absence of disease or frailty as health indicators. The relation between physical activity (PA), subjective well-being (SWB), natural environment, and present moment awareness (PMA) remains unexplored. The presented qualitative review offers a perspective model of the relationship between physical activity, natural environment, and awareness of the present moment that helps us explore its underlying, relating pathways. Our review concludes that present moment awareness can be worthy of attention to detect the impact of physical activity, subjective well-being and staying in a natural environment on selected samples, as well as its influence on maximizing related benefits for health and well-being. The challenge after that is to consider how to monitor the complex interactions that will occur within the multiple levels of influence. Essentially, a unified model of research and practice which incorporates physiological and psychological theories is undoubtedly needed. If that happens, we can understand the role of the diverse regulators upon behavior and proceed to convey this evidence into future health-promoting interventions.

Background/Objectives: University students are a population vulnerable to psychological distress due to academic and lifestyle transitions. This study examined the relationships between physical activity (PA), sedentary behavior, and subjective well-being among Slovak university students, with attention to gender-specific and non-linear patterns. Methods: A total of 1314 first-year students (69.5% women; mean age = 20.7 ± 1.4 years) completed the IPAQ-Short Form and the Bern Questionnaire on Subjective Well-Being (BSW/A). PA levels were categorized as low, moderate, or high according to standard MET thresholds. Group differences were analyzed using nonparametric tests with Benjamini–Hochberg FDR correction. Results: Higher PA levels were associated with more favorable well-being outcomes, particularly higher self-esteem and joy of life and lower depressed mood and somatic complaints. Effect sizes ranged from small to moderate. Gender-specific patterns emerged: among men, well-being indicators tended to plateau beyond moderate PA, whereas among women, moderate PA showed an inverse association with self-esteem despite slightly higher median scores in the moderate-activity group. Sedentary time showed weak and mostly non-significant associations after FDR correction. Conclusions: Physical activity was positively associated with subjective well-being in a non-linear, gender-dependent manner. These findings suggest that approaches to supporting student well-being may benefit from considering gender differences, individual activity patterns, and motivational context.
