Essential and xenobiotic elements in cottage cheese from the Slovak market with a consumer risk assessment.

The examination of various elements in the milk products is very important in the food sector in respect of food quality and safety. The aim of this study was to determine the concentrations of calcium (Ca), cobalt (Co), cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), mercury (Hg), potassium (K), magnesium (Mg), sodium (Na), nickel (Ni), phosphorus (P), lead (Pb) and zinc (Zn) in white cottage cheese or cottage cheese supplemented with various additives (white, lacto-free, chive, tzatziki, mustard + onion, chili, active protein) available on the market of Slovakia. All essential elements were within the reference range. Cottage cheese enriched with tzatziki showed higher amount of Cu, Fe, K, and Zn. Mustard + onion cheese contained high values of Ca, Co, Mg, and Ni. In white cottage cheese high amount of Cr, Mn, and P was measured. The content of xenobiotic metals was below permitted limit. The contribution to PTWI (Provisional tolerable weekly intake) suggested very low dietary exposure to heavy metals as Cd, Hg, and Pb as well as other metals (Cu, Ni, and Zn) in cottage cheese. Numerous correlations between concentrations were observed. MOE (Margin of Exposure) evaluation denoted that average consumption of cottage cheese does not pose any high cardiovascular and nephrotoxicity threat.

Detection of selected trace elements in yogurt components.

The objective of this study was to determine the concentrations of Cu, Cd, Pb, Mn, Cr, Co, Ni, Zn, and Hg in the white and fruit parts of commercially available yogurts (n = 30) from Nitra markets (Slovak Republic). The results were correlated to determine their relationships. Three yogurt fruit flavors were chosen and tested, strawberry (n = 10), blueberry (n = 10), and cherry (n = 10). The elements were analyzed using atomic absorption spectrophotometry. Higher concentrations of toxic elements, such as Cd and Pb, were found in the fruit parts of the yogurt, and in some cases, the tolerable limit was exceeded. The white part of the yogurt was not contaminated by toxic elements. White yogurt is a good source of nutrients for humans, but the fruit part in yogurt requires detailed monitoring and improvements in the processing techniques.

Relationship between air pollution and metal levels in cancerous and non-cancerous lung tissues.

We aimed to check the relationships between levels of metals (Ca, Cd, Cu, Fe, Hg and Zn) in cancerous and non-cancerous lung tissues and their link to air pollution, expressed as particulate matter (PM) concentrations. The study also examines the influence on metal concentration in the lung tissue of patients' sex and the distance of their homes from the nearest emitter. We found that the general pattern of ascending concentrations in tumor tissue was as follows: Hg < Cd < Cu < Ca < Zn < Fe. In non-affected lung tissue the order of concentrations of Ca and Fe was reversed. With the exception of Cd and Cu, levels of metals were found in higher accumulations in non-cancerous tissue (e.g., Fe 326.423 and Ca 302.730 µg/g d.w) than in tumorous tissue (Fe 150.735 and Ca 15.025 µg/g d.w). Neither the PM10 (PM of a diameter of 10 µm) concentration nor sex revealed any connection with metal concentrations. The shorter the distance from the emitter, the higher the metal concentrations that tended to be observed for almost all metals, but a statistically significant (but weak) relationship was noted only for Cu in tumor tissue (rs: -0.4869).

Accumulation of metals in cancerous and healthy tissues of patients with lung cancer in Southern Poland.

The aim of this study was to investigate whether the concentrations of metals differ among patients with and without lung cancer with different smoking status and living in industrialized environments. We also evaluated the relationships between metals and blood parameters including hematocrit level (Hct), hemoglobin concentration (Hb), red (RBC) and white (WBC) blood cells numbers. Concentrations of metals were measured with AAS (copper - Cu, iron - Fe, magnesium - Mg, zinc - Zn) and CV-AAS (mercury - Hg). Neither smoking status nor industrialization could be considered as a significant factor for metals accumulation in blood, lungs and tumor tissues, with the exception of mercury which differed in the aspect of industrialization. According to the type of the disease, Fe, Hg and Mg concentrations differed significantly in lungs. Correlations between metals and blood parameters were observed. Additionally, concentrations of Mg, Cu and Zn were correlated between lungs and tumor tissue of patients with cancer as well as they all were related to each other in lungs, tumor and blood tissues.

Blood concentration of copper, cadmium, zinc and lead in horses and its relation to hematological and biochemical parameters.

Environmental pollution results in serious health hazards to animals and blood analysis serves as a good alternative for health status assessment. The target of this study was to analyze the concentration of selected metals in equine blood, to analyze the blood parameters and to find possible correlations. Blood samples were collected from the vena jugularis of healthy adult horses. The highest concentration of all elements was found in whole blood (Cu 3.84 ± 0.90 mg L(-1); Cd = 0.81 ± 0.90 mg L(-1); Zn 26.67 ± 14.12 mg L(-1); Pb 9.33 ± 5.76 mg L(-1)). Higher concentrations of copper, cadmium, zinc and lead were detected in blood clots compared to blood sera (44.04%). A similar tendency was found for cadmium (50%), zinc (13.08%) and lead (46.02%), which showed generally higher concentrations in blood clots (cells). Correlation analysis proved some relations between analyzed elements. In blood clots there is a strong positive correlation between Cd - Pb (r = 0.93) and Zn - Pb (r = 0.71) was detected. For biochemical and hematological parameters mainly medium correlations were detected. Obtained results prove different correlations of analyzed elements in blood components as well as the effect on parameters of blood biochemical and hematological profiles.

Levels of Essential and Trace Elements in Mozzarella Available on the Slovak Market with the Estimation of Consumer Exposure.

The aim of this study was to determinate the content of some elements in a specific dairy product, mozzarella, in a particular area of western Slovakia and to evaluate the estimation of the risk to the consumers based on the contribution to the provisional tolerable weekly intake. The consumption of mozzarella can contribute to the intake of important elements in the diet, such as calcium and magnesium, along with others. The contents of some toxic and trace elements were low and have not exceeded the permitted limit. In addition, the contribution to PTWI was found to be very low, which means that the consumption of mozzarella possesses no risk to humans. It is concluded that the data obtained in this study can help as a valuable addition to methodological and scientific material in the field of food safety of dairy products and their positive impact on human health.

Concentrations of cadmium, copper and zinc in tissues of mallard and coot from southern Poland.

The aim of this study was to present the content of cadmium, copper and zinc in tissues of the most common game waterbirds from southern Poland. Concentrations of the three metals were measured in brain, pectoral muscle, heart muscle, liver and kidney of mallard (n = 10) and coot (n = 10) shot in 2003 on fishponds around Zator, Southern Poland. The lowest concentrations were noted in the case of cadmium. Its highest median occurred in kidney (mallard 8.4251 µg/g d.w., coot 5.0704 µg/g d.w.). Average concentrations of this element in muscles oscillated in both species around 0.94 µg/g d.w. In the comparison of cadmium concentrations to the safety norms for consumable meat, almost all samples were non-fit for human consumption. Copper concentrations showed a significant variation between species but their range in different tissues was generally narrow. The highest median was noted among mallards in liver (39.4863 µg/g d.w.) and among coots in pectoral muscle (40.2684 µg/g d.w.). Zinc concentrations did not differ statistically between species only in the case of liver and kidney. Median of this element hit to 98.4883 µg/g d.w. (liver of mallard) and 107.6153 µg/g d.w. (heart muscle of coot). No statistically significant correlations between concentrations of studied metals in different samples were noted. Concentrations of study elements were also evaluated in environmental samples. Water contained trace amounts of researched elements (medians from 0.0401 for Cd to 0.1251 mg/L for Cu). In deposit and forage samples, zinc occurred in the highest concentration (median up to 56.7701 µg/g d.w.).

[Effects of the cigarette smoking on the newborn clinical parametrs and the accumulation of cadmium and lead in the placenta of women from Upper Silesia]. / Wplyw palenia papierosów na parametry noworodka oraz na kumulacje kadmu i olowiu w lozysku kobiet z Górnego Slaska.

AIM: The aim of the study was to determine the content of cadmium and lead in different parts of the placenta and fetal membranes of women who were exposed to cigarette smoke. The correlation between the two chemical elements and the impact of the Cd and Pb accumulation on newborn parameters were established. MATERIALS AND METHODS: The study material was collected immediately after delivery from 40 patients of the Department of Obstetrics and Gynecology Katowice. The marginal and central parts of the placenta and fetal membranes (amnion) were taken. The women were divided into two groups: smokers and non-smokers. Metal concentration in placenta was determined by flame atomic absorption spectrometry (FAAS). Bioethical Commission approved of the study RESULTS: In both studied groups, smokers and non-smokers, the presence of cadmium and lead was detected. Smokers turned out to have accumulated more of the investigated heavy metals in the placenta and fetal membranes. In the analyzed groups of women of smokers and non-smokers, differences in the content of the studied metals were found, but they were not statistically significant. Differences in newborn parameters in the two groups of women occurred, but again they lacked statistical significance. The level of lead increases along with the increase in the amount of cadmium, which proves the existence of a statistically significant correlation between them (p = 0.000). CONCLUSIONS: The number of smoked cigarettes increases cadmium content in maternal placenta and fetal membranes. No significant differences in newborn parameters of either smoker or non-smokers were observed, which may indicate women's adaptation to the environment containing cigarette smoke. The placenta and fetal membranes are biomarkers of the level of toxic exposure for the developing baby.

Accumulation of risk elements in kidney, liver, testis, uterus and bone of free-living wild rodents from a polluted area in Slovakia.

Free-living wild rodents are usually used as indicators of pollution, with elements being determined in either whole body or in specific organs. In the present study, the accumulation of cadmium (Cd), copper (Cu), iron (Fe), and zinc (Zn) in kidney, liver, testis, uterus and bone of yellow-necked mice (Apodemus flavicollis) and bank voles (Myodes glareolus) trapped in a polluted area of Nováky, Slovakia was investigated. Yellow-necked mice and bank voles were collected using standard theriological methods for wood ecosystems. All animals were adults in good physical condition. Concentrations of Cd, Cu, Fe, and Zn in all analyzed organs were determined by atomic absorption spectrophotometry. The highest concentrations of Cd and Zn were found in the bone of both species while Cu and Fe accumulated most in the uterus. Significantly higher concentrations of Cd and Cu were detected in the liver of the bank vole in comparison with the yellow-necked mouse (P<0.05). Similar significantly higher levels of Cd and Zn were found in the bone of the bank vole (P<0.05) than in the yellow-necked mouse, while these rodents had significantly higher Cu and Fe concentrations (P<0.05) in the kidney. Significantly higher levels of Fe and Zn were detected in the testis and uterus of bank voles, respectively. On the other hand, significantly higher concentration of Cu was found in the testis of yellow-necked mice. Results of this study suggest that bank voles are more sensitive heavy metal loaded bioindicators than yellow-necked mice.

Accumulation of zinc, nickel, lead and cadmium in some organs of rabbits after dietary nickel and zinc inclusion.

This study reports the effect of dietary nickel (Ni) and a combination of Ni and zinc (Zn) on the accumulation of lead (Pb), cadmium (Cd), Ni and Zn in muscles, liver and kidneys of rabbits. Female rabbits (Oryctolagus cuniculus) of experimental groups were fed a granular mixture with addition of various concentrations of Ni or Ni+Zn (E1 - 17.5 g NiCl(2) per 100 kg of feed mixture, group E2 - 35.0 g NiCl(2) per 100 kg of feed mixture, group E3 - 17.5 g NiCl(2) per 100 kg of feed mixture and 30 g ZnCl(2) per 100 kg of feed mixture, group E4 - 35.0 g NiCl(2) per 100 kg of feed mixture and 30 g ZnCl(2) per 100 kg of feed mixture). Group C without inclusion of Ni or Zn served as control. After the 90-day experimental period biological material (liver, kidney, musculus longissimus dorsi, musculus biceps femoris) was taken from the animals. Samples were analyzed by the AAS method. Ni added to the FM caused an increase in Cd concentration in the kidneys of the rabbits, significantly in the E3 group in comparison with the control group. In the liver an insignificant decrease of Cd concentration was found. Zn addition in the amount of 30 g to the diet caused an increase of Cd level in the kidney as well as in the liver. Ni and Zn treatment caused a significant decrease of Pb accumulation in the m. longissimus dorsi of rabbits. This study indicates that dietary inclusion of Ni and Zn caused specific interactions among the observed metals.

Effects of Selected Metal Nanoparticles (Ag, ZnO, TiO2) on the Structure and Function of Reproductive Organs.

Various studies have shown that the reproductive organs are highly sensitive to toxic elements found in the environment. Due to technological progress, the use of nanoparticles has become more common nowadays. Nanoparticles are used for drug delivery because their dimensions allow them to circulate throughout the body and enter directly into the cell. Antimicrobial properties are increasingly used in the manufacture of medical devices, textiles, food packaging, cosmetics, and other consumer products. Nanoparticles provide several benefits, but aspects related to their effects on living organisms and the environment are not well known. This review summarizes current in vivo, and in vitro animal studies focused on the evaluation of toxicity of selected metal nanoparticles (Ag, ZnO, TiO2) on male and female reproductive health. It can be concluded that higher concentrations of metal nanoparticles in the male reproductive system can cause a decrease in spermatozoa motility, viability and disruption of membrane integrity. Histopathological changes of the testicular epithelium, infiltration of inflammatory cells in the epididymis, and prostatic hyperplasia have been observed. Nanoparticles in the female reproductive system caused their accumulation in the ovaries and uterus. Metal nanoparticles most likely induce polycystic ovary syndrome and follicular atresia, inflammation, apoptosis, and necrosis also occurred.

In vitro effect of nickel on bovine spermatozoa motility and annexin V-labeled membrane changes.

In this study the effect of in vitro culture of bovine spermatozoa with nickel (NiCl(2)) on spermatozoa motility and membrane changes was analyzed. The spermatozoa motility significantly decreased after 120 min of culture at the concentration of 1000 µM Ni ml(-1) (P < 0.05) and after 240 min of culture at the concentration of 500 and 1000 µM Ni ml(-1) (P < 0.001) as compared with control. The progressive motility was the highest in the control group and in the groups with the lowest nickel concentrations (7.8 and 125 µM Ni ml(-1)). The progressive spermatozoa motility was significantly altered even after 30 min of culture in the group with the highest nickel concentration (1000 µM Ni ml(-1)). A significant decrease in progressive motility from the concentration of 250 µM Ni ml(-1) was detected after 240 min of culture. Concentrations from 125 µM Ni ml(-1) in various time periods of culture stimulated spermatozoa motility after 30 min (P < 0.001), but later an inhibitory effect was noted. After 240 min of in vitro spermatozoa culture with 125 µM Ni ml(-1) a typical Annexin V fluorescence reaction was detected. Fluorescence was detected in mitochondrial segment of bovine spermatozoa. In spermatozoa exposed to higher nickel concentrations the Annexin V-positive reaction was detected also on the spermatozoa head membrane. In the group with the highest concentration and the longest time of exposure (1000 µM Ni ml(-1); 240 min) the apoptotic Annexin-positive regions were detected not only in the mitochondrial part, but also in the spermatozoa head (acrosomal and postacrosomal part), showing significant alteration of spermatozoa membrane integrity.

Exogenous Factors Affecting the Functional Integrity of Male Reproduction.

Natural processes along with increased industrial production and the irresponsible behavior of mankind have resulted in environmental pollution. Environmental pollutants can be categorized based on their characteristics and appearance into the following groups: physical, biological, and chemical. Every single one of them represents a serious threat to the male reproductive tract despite the different modes of action. Male gonads and gametes are especially vulnerable to the effect of exogenous factors; therefore, they are considered a reliable indicator of environmental pollution. The impact of xenobiotics or radiation leads to an irreversible impairment of fertility displayed by histological changes, modulated androgen production, or compromised spermatozoa (or germ cells) quality. The present article reviews the exogenous threats, male reproductive system, the mode of action, and overall impact on the reproductive health of humans and animals.

Effect of Three Months Pilates Training on Balance and Fall Risk in Older Women.

This study assessed the effect of Pilates exercises on balance and fall risk in older women. Participants comprised 50 older women aged over 60 years, divided randomly into two groups: the experimental group (n = 30), which took part in Pilates sessions two times per week for three months, and the control group (n = 20). The control group did not participate in such sessions but also did not participate in any other rehabilitation programs or additional physical activity except everyday activities. Before and after the training cycle, all women underwent an assessment using Timed Up and Go (TUG), the One Leg Stance Test (OLST), a test performed on a Freestep baropodometric platform, and the tests performed on a Biosway platform. After the training, significantly decreased values of the surface of the ellipse (p = 0.0037) and mean values of velocity (p = 0.0262) for the right foot in the experimental group were observed. The Limits of Stability (LoS) test (p = 0.005) and the Modified Clinical Test of Sensory Interaction on Balance (m-CTSIB) performed on an unstable surface with eyes closed (p = 0.0409) indicated statistically significant changes in the experimental group. None of the above changes were statistically significant in relation to the control group. Pilates training affected the participants' balance by improving LOS and reducing fall risk.

Concentration of lead, cadmium, mercury and arsenic in leg skeletal muscles of three species of wild birds.

The aim of this study was to monitor accumulation of lead, cadmium, mercury and arsenic in leg skeletal muscle of some wild birds from selected areas of Slovakia and the correlations among the heavy metals. A total of 160 wild birds representing 3 species-Eurasian coot (Fulica atra) (n = 24), mallard (Anas platyrhynchos) (n = 68) and pheasant (Phasianus colchicus) (n = 68) were involved for analyses. Concentrations of heavy metals from samples were measured using atomic absorption spectrophotometry (AAS). Metal concentrations are expressed as mg/kg wet weight. The order of lead and arsenic concentrations in muscles of wild birds were as follows: mallard > pheasant > Eurasian coot; in the case of arsenic the differences were significant (P < 0.05). Muscle of Eurasian coot accumulated the highest concentration of cadmium and mercury followed by pheasant and the lowest in mallard, but differences were not significant (P > 0.05). Moderately negative correlations were noted in pheasant between cadmium and mercury (r = -0.39), and between mercury and arsenic (r = -0.45). Moderately negative correlation between cadmium and arsenic (r = -0.31) was found for Eurasian coot.

Heavy metal content in the femora of yellow-necked mouse (Apodemus flavicollis) and wood mouse (Apodemus sylvaticus) from different types of polluted environment in Slovakia.

Heavy metal content in the femora of yellow-necked mouse (Apodemus flavicollis) and wood mouse (Apodemus sylvaticus) caught in different polluted biotopes of a low hill level in Slovakia (Nováky and Kolínany) was investigated in the present study. Length, weight and histological structure of mouse bones have also been analysed. According to our results, higher concentrations of Cd, Ni, Fe, Cu and Zn were detected in the femora of A. flavicollis from Kolínany area. Similarly, we observed higher concentrations of Ni, Fe, Cu and Zn in the bones of A. sylvaticus trapped at the same biotope. Significant differences were observed for concentrations of Ni and Zn in both species (P<0.05). The measured values for bone length and bone weight were higher in yellow-necked mice and wood mice from Nováky locality (P<0.01). Histological observation of thin sections from femora of A. flavicollis and A. sylvaticus revealed an outer and inner non-vascular lamellar layer around a poorly developed reticular layer. We did not identify demonstrable changes in qualitative histological characteristics of the femora between the mice (A. flavicollis and A. sylvaticus separately) from different types of polluted environment. Also, no statistically significant differences for all the measured variables of primary osteons' vascular canals were observed. Correlation analysis in yellow-necked mouse showed high positive relation between bone weight and bone length (r=0.66), area and perimeter (r=0.87) and perimeter and maximum diameter (r=0.87). In wood mouse, high positive correlation between bone weight and bone length (r=0.80), area and perimeter (r=0.72), area and maximum diameter (r=0.66) and perimeter and maximum diameter (r=0.74) was found. Our results demonstrate slightly elevated accumulation of some heavy metals in the femora of yellow-necked mouse and wood mouse from Kolínany biotope and thus give an evidence of a contamination of the environment.

Effects of Cadmium, Lead, and Mercury on the Structure and Function of Reproductive Organs.

Reproductive organs are essential not only for the life of an individual but also for the survival and development of the species. The response of reproductive organs to toxic substances differs from that of other target organs, and they may serve as an ideal "barometer" for the deleterious effects of environmental pollution on animal and human health. The incidence of infertility, cancers, and associated maladies has increased in the last fifty years or more, while various anthropogenic activities have released into the environment numerous toxic substances, including cadmium, lead, and mercury. Data from epidemiological studies suggested that environmental exposure to cadmium, lead, and mercury may have produced reproductive and developmental toxicity. The present review focused on experimental studies using rats, mice, avian, and rabbits to demonstrate unambiguously effects of cadmium, lead, or mercury on the structure and function of reproductive organs. In addition, relevant human studies are discussed. The experimental studies reviewed have indicated that the testis and ovary are particularly sensitive to cadmium, lead, and mercury because these organs are distinguished by an intense cellular activity, where vital processes of spermatogenesis, oogenesis, and folliculogenesis occur. In ovaries, manifestation of toxicity induced by cadmium, lead, or mercury included decreased follicular growth, occurrence of follicular atresia, degeneration of the corpus luteum, and alterations in cycle. In testes, toxic effects following exposure to cadmium, lead, or mercury included alterations of seminiferous tubules, testicular stroma, and decrease of spermatozoa count, motility and viability, and aberrant spermatozoa morphology.

Levels of Essential and Xenobiotic Elements and Their Relationships in Milk Available on the Slovak Market with the Estimation of Consumer Exposure.

The monitoring of various elements in the cow milk is important in the agricultural sector. The goal of this study was to determine the concentrations of calcium (Ca), cadmium (Cd), copper (Cu), iron (Fe), mercury (Hg), potassium (K), magnesium (Mg), sodium (Na), nickel (Ni), lead (Pb), and zinc (Zn) in the milk samples coming from different origins (local region in Nitra, nationwide sample represents the common Slovak brands of milk and common brands of milk from Czech Republic widely available in Slovakia). The samples were analyzed using atomic absorption spectrometry. A high level of variability in the Cu, Fe, Na, Ni, and Zn contents was observed. Magnesium was comparatively high in the milk sample from Slovakia (273.23 ± 16.32 µg/mL) against sample from Nitra (230.91 ± 9.48 µg/mL) and Czech Republic (202.70 ± 10.83 µg/mL). Potassium was significantly higher in milk from Nitra region (3301.98 ± 95.66) against SK sample (2925.16 ± 75.74 µg/mL). There were no significant differences in other elements among the three regions. The provisional tolerable weekly intake (PTWI) contribution suggested low dietary exposure to observed toxic metals (Cd, Hg, and Pb) in milk samples. Margin of exposure (MOE) evaluation denoted that even higher consumption of milk poses no high cardiovascular and nephrotoxicity threat. However, Cd and Pb are known for their cumulative effect and the monitoring of these elements in milk is strongly required.

Blood mercury levels in mute swans (Cygnus olor) are not related to sex, but are related to age, with no blood parameter implications.

Concentrations of mercury (Hg) were examined in the blood of mute swans from rural breeding sites and urban wintering areas in southern parts of Poland, Europe. The birds were classified into three age groups: cygnets, juveniles and adults. To investigate the potential impact of Hg on birds, hematocrit (Ht), reduced glutathione (GSH) levels and morphometric measurements were taken. Using morphometric parameters, we stated that all mute swans sampled were in good condition. The mercury concentrations found were rather low and differed between birds from industrialized wintering areas and rural breeding areas (means 7 ng/mL and 2 ng/mL, respectively). We found no difference in Hg concentrations between the sexes, but concentrations varied significantly between age groups (cygnets 2 ng/mL, juveniles 7 ng/mL and adults 6 ng/mL). A similar trend was observed for hematocrit levels. GSH levels did not differ between any of the groups studied. We found no significant relationship between blood parameters (Ht, GSH) in relation to Hg concentrations. We conclude that the Hg concentrations in blood may be influenced by industrialization, season and age, but generally low concentration such as those found by us do not affect Ht and GSH levels.

Biogenic and Risk Elements in Wines from the Slovak Market with the Estimation of Consumer Exposure.

Wine consumption delivers macroelements and microelements necessary for the proper metabolism. On the other hand, wine can be an important source of toxic metals. The aim of this study was to estimate the concentrations of Ca, Cd, Cu, Fe, Hg, Mg, Ni, Pb, and Zn in the Slovak and non-Slovak wines. The concentration of metals was evaluated with respect to the type, the alcohol content, and the age of Slovak wine. The general scheme of concentrations found was as follows Ca > Mg > Fe > Zn > Pb > Cd > Ni > Cu > Hg. The type of wine and the alcohol content do not have a significant impact on metal concentrations. Also, the age of wine has no influence on the mean concentration of metals, except for Zn. Metal concentrations in Slovak and non-Slovak wines indicate similar contents of metals, except for Ni. The contribution to both dietary reference values (DRVs) and provisional tolerable weekly intake (PTWI) evaluations in the Slovak wine suggested low dietary exposure to Ca, Cu, Fe, Mg, Ni, Zn, Cd, Hg, and Pb, respectively. However, we do not suggest that the consumption of all Slovak wines is healthy. The maximum Pb concentrations in Slovak wines exceed the maximum permitted level proposed by the European Commission. This might be proved by the results of the margin of the exposure (MOE) value evaluation in the samples containing the maximum Pb concentrations, showing a high risk of CKD and SBP in high and extreme consumption groups.
