Current trends are promoting youth, beauty, health, and fitness. Individuals often seek out remedies, such as medicines or dietary supplements (DS), to achieve these goals. However, highly processed foods, chronic stress, and environmental pollution contribute to the development of civilization diseases.

The aim of the study was to assess whether the elemental composition of the maxillary bone from individuals belonging to a given population reflects the environmental exposure of this population to lead and cadmium. The research material consisted of cortical bone from the anterolateral walls of the maxilla collected from 126 patients during Caldwell-Luc maxillary sinus surgery on residents of two cities differing in terms of the lead and cadmium pollution of the natural environment.

Vegetable and fish oils constitute a significant part of all dietary supplements. Due to increasing environmental pollution, the raw materials used for their production may be contaminated with toxic substances, including metals. The aim of the present study was to determine the mercury (Hg) content in vegetable oils, shark liver oils, and cod liver oils.

Due to the content of active ingredients, teas can be used prophylactically, but most of all they are consumed for taste reasons. As with food or water, these products can be contaminated with heavy metals, including mercury. Mercury (Hg) is a toxic element, it causes many side effects in the human body depending on the form of Hg, which can include respiratory failure, kidney damage, neurological disorders.

This survey was conducted in the years 2019 to 2020 using a group of 193 people, 124 females and 69 males, at two Silesian universities.
Aim: The purpose of this survey was to estimate patterns concerning use of tobacco and psychoactive substances by students.
Honey is a highly valued product due to its nutritional value, pro-health and healing properties. Pollutants from the environment penetrate into nectar, honeydew, pollen and next into bee products and can cause human exposure after ingestion. Mercury (Hg) is a toxic metal to living organisms.

The aim of this study was to determine whether impacted mandibular teeth and the surrounding bones can be used as biomonitoring media to assess exposure to heavy metals.
Methods: The research materials were 67 impacted lower third molars and samples of the cortical bone removed when the wisdom teeth were surgically extracted.
Malnutrition, manifested by both overweight and underweight, can lead to serious health consequences. The subject of the study was to determine the concentration of elements such as chromium (Cr), calcium (Ca), copper (Cu), iron (Fe) and manganese (Mn) in children's deciduous teeth in relation to their body weight. The calculated body mass index (BMI) values and an application of the growth chart showed that 59% of children among the studied sample had normal weight.

For these studies, we used a microfluidic system combined with fluorescence microscopy techniques, which enabled analysis of cells' morphology, viability, and QDs uptake. PDMS and glass-based microfluidic system enabled the precise control of the cell environment, allowed to examine five replications of each tested QDs concentrations (statistically significant number), monitor multiple cellular events, and avoid manual preparation of QDs dilutions.

The aim of this study was to describe the issue of changes in the concentration of some elements (Mn, Fe, Mg, Cu, K, Cr, Pb, Cd, and Ca) in the mineral composition of deciduous teeth and to answer the question whether there was a tendency to change the metal concentration, depending on children's age. Physiological replacement of deciduous teeth is preceded with the remodeling process occurring in the mineral structure. The elemental composition of deciduous teeth tissue during their natural loss is the result of these transformations.

In addition, the concentration of (40)K in soils of the investigated area was measured. Below the litter layer (mean thickness 3 cm), the soil samples were collected up to a depth of 12 cm and then divided into three layers: 0-3, 3-7, 7-12 cm.

It has been found that the concentrations of metals were significantly higher in the deciduous teeth than in permanent ones. Regression analysis and principal component analysis revealed an increased dynamics of the processes of binding the elements by the hydroxyapatite of deciduous teeth.

The elemental composition of gallstones was determined with ICP-AES method (Inductively Coupled Plasma - Atomic Emission Spectroscopy). Studies on copper occurrence in concretions of gallstones showed the presence of its higher concentrations in case of smoking women (9.
