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 elemental composition of the body's calcified tissues may reflect the environmental exposure of the population to heavy metals. 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.

Introduction: These days, it is observed worldwide that the number of smokers drops, however, use of e-cigarettes and other psychoactive substances becomes more popular. 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.

Background: The elemental composition of bones and teeth can allow exposure to heavy metals in the environment to be estimated. 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.

The presented work aimed at systematic investigation of biological activity of CdSex S1- x /ZnS and CdSe/ZnS quantum dots (QDs), whose surface was modified with different ligands. 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 study determines the concentration of Ba in mineralized tissues of deciduous teeth, permanent impacted teeth, and facial bones. The study covers the population of children and adults (aged 6-78) living in an industrial area of Poland. Teeth were analyzed in whole, with no division into dentine and enamel.

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.

The study addressed chromium, zinc and magnesium concentrations in the pubic hair of obese and overweight women. It was carried out on hair collected from 85 women at the age of 16-80 living in the Podkarpackie Voivodeship (southern Poland). The experimental and control groups consisted of 39 and 46 females, respectively.

The vertical (137)Cs profile of forest and wasteland soils was analyzed in the south of the Podlasie Lowland area (Eastern Poland) about 20 years after the Chernobyl accident. 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.

The study shows the results of research on the concentrations of metals (Cd, Pb, Mn, Cu, Cr, Fe, Zn, Na, K, Mg, and Ca) in deciduous and permanent teeth with respect to their location in the oral cavity (maxilla, mandible). 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 studies were carried out on the changes in copper content in concretions of gallstones which were taken from 146 women (49 smoking and 97 no smoking) and 24 men (11 smoking and 13 no smoking), respectively. 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.

In this work the changes of lead (Pb) and chromium (Cr) content in deciduous children teeth exposed on environmental tobacco smoking were presented. As the control group were given deciduous children teeth nonexposed on tobacco smoking in home. The content of lead in deciduous teeth was higher in non-exposed population (13.

The aim of this study was investigation influence sex and place living (industrial region or village) to concentration of: Ca, K, Mg and Na in pharyngeal tonsils (n = 84) from children exposed and unexposed to tobacco smoke and analysis kind of interactions between trace elements. Determination of these elements contents were performed by ICP-AES. It was found higher concentrations of Ca and Na in pharyngeal tonsils from boys (389 microg//g) and girls (356 microg/g) unexposed to tobacco smoke to comparison to expose to ETS boys (304 microg/g) and girls (298 microg/g).

Mercury concentration in gallstones of 146 women (49 smoking, 97 non-smoking) and 24 men (11 smoking, 13 non-smoking) was determined employing Inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP-AES). The possibility of mercury accumulation in concretions in the gallbladder was confirmed by the study. The changes of given elements were different in comparison for smoking and non smoking women and men.
