[PMID: 38878468 DOI: 10.1016/j.jtemb.2024.127481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Revised: 05/27/2024] [Accepted: 06/05/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND The use of protein supplements by athletes has risen due to their effectiveness in meeting dietary needs. However, there is a growing concern about the presence of potentially toxic metals (PTMs. Al, Cr, Mn, Ni, Cu, Zn, Cd, and Pb) in these supplements. Consequently, it is crucial to evaluate the levels of these PTMs to ensure the safety of the supplements. METHODS The objective of the current study was to assess the PTMs concentrations in protein supplements and examine any possible health hazards. Twenty-five samples of protein supplements were purchased from different pharmacies to screen them for metals. Inductively coupled plasma-optical emission spectrometry (ICP-OES) was utilized to analyze metal content. Additionally, chemometric methods such as Pearson's correlation coefficient (PCC), principal component analysis (PCA), and hierarchical cluster analysis (HCA) were employed to identify possible sources of PTMs contamination in protein supplements. RESULTS Concentration ranges for PTMs were found as, Al (0.03-3.05 mg/kg), Cr (0.11-0.89 mg/kg), Mn (1.13-8.40 mg/kg), Ni (0.06-0.71 mg/kg), Cu (1.05-5.51 mg/kg), Zn (2.14-27.10 mg/kg), Cd (0.01-0.78 mg/kg), and Pb (0.06-0.57 mg/kg). The weekly intake of Cd exceeded the level of tolerable weekly intake (TWI) set by the European Food Safety Authority (EFSA). CONCLUSION Athletes, bodybuilders, fitness enthusiasts, dieters, young adults and adolescents, and health-conscious individuals should be conscious of Cd concentration as it does not compliance the TWI set by EFSA. Target hazard quotient (THQ < 1), hazard index (HI < 1), margin of exposure (MOE ≥ 1), percentile permitted daily exposure (% PDE < 100), and cumulative cancer risk (CCR < 1 × 10-3) analyses revealed that there are no appreciable non-carcinogenic and carcinogenic health risks associated with the use of these products.

[PMID: 39127121 DOI: 10.1016/j.fct.2024.114915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 08/04/2024] [Accepted: 08/07/2024] [Indexed: 08/12/2024]
Abstract
There is a lack of information regarding the presence of heavy metals in feed ingredients for animals. Therefore, this study examines 10 feed samples collected from commercial pet food in South African market. The optimal working parameters for ultrasound assisted hydrogen peroxide extraction (UA-HPE) confirmed by multivariate optimization were sonication temperature at 80 °C for 60 min, sample mass of 0.1 g, and H2O2 concentration of 5 mol/L. The UA-HPE results demonstrated high accuracy of (>95%), reproducibility (≤1.9%), low method of detection limits (0.3498 and 0.49 μg/g), and strong linearity as confirmed by regression analysis. The environmental friendliness of the UA-HPE method was assessed using AGREEPrep metric tool that resulted with a score of 0.74. The concentration levels of Cd, Pb and As, ranged between 0.86 and 11.34, 4.50-11.45, and 2.61-12.5 μg/g, respectively greater than the standardized limits, whilst Cr, and Sn were below the limits of detection in all pet food. The health index calculations (HI > 1) revealed that the cat, dog, and horse feed pose health risk for animal consumption. Consequently, this study demonstrated a green, efficient, and cost-effective method for the analysis of animal feed with high accuracy.

Contamination of trace, non-essential/heavy metals in nutraceuticals/dietary supplements: A chemometric modelling approach and evaluation of human health risk upon dietary exposure. Food Chem Toxicol 2024; 190:114806. [PMID: 38852757 DOI: 10.1016/j.fct.2024.114806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 05/27/2024] [Accepted: 06/06/2024] [Indexed: 06/11/2024]
Abstract
Across the world, nutraceuticals/dietary supplements are commonly consumed without medical supervision, and believing these products are harmless to health. However, these products may contain trace (TMs) and non-essential/heavy metals (nHMs) as contaminants at levels higher than the recommended daily allowance (RDA), which can be hazardous to human health. Consequently, it is crucial to assess the levels of these metals to ensure the safety of these products. This study aimed to analyze the concentration of TMs (Mn, Cu and Zn) and nHMs (Al, Cr, Ni, Cd and Pb) in nutraceuticals/dietary supplements. Metal analysis was conducted using inductively coupled plasma-optical emission spectrometry (ICP-OES). Multivariate and bivariate analysis including principle component analysis (PCA), hierarchical cluster analysis (HCA) and Pearson correlation coefficient (PCC) were applied to understand inter-metal association and sources of these metals. Concentration ranges for TMs were found as, Mn (0.2-4.3 mg/kg), Cu (0.11-2.54 mg/kg), and Zn (0.1-22.66 mg/kg) while the nHMs concentration ranges were: Al (0.046-3.336 mg/kg), Cr (0.11-1.63 mg/kg), Ni (0.18-0.72 mg/kg), Cd (0.04-0.92 mg/kg), and Pb (0.18-1.08 mg/kg). The levels of tolerable dietary intake (TDI) for Cr and Ni, and the provisional tolerable monthly intake (PTMI) limit for Cd, exceeded the values set by the World Health Organization (WHO) and the European Food Safety Authority (EFSA). The estimation of the target hazard quotient (THQ <1), hazard index (HI < 1) and cumulative cancer risk (CCR <1 ✕ 10-3) indicated no significant non-carcinogenic and carcinogenic health risks associated with consuming these products. Therefore, the primary recommendation from this study is to use the nutraceuticals/dietary supplements should be under the supervision of dietitian.

Assessment of carcinogenic and non-carcinogenic risk of exposure to potentially toxic elements in tea infusions: Determination by ICP-OES and multivariate statistical data analysis. J Trace Elem Med Biol 2024; 84:127454. [PMID: 38669815 DOI: 10.1016/j.jtemb.2024.127454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 03/17/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND The perennial evergreen tea (Camellia sinensis) plant is one of the most popular nonalcoholic drinks in the world. Fertilizers and industrial, agricultural, and municipal activities are the usual drivers of soil contamination, contaminating tea plants with potentially toxic elements (PTEs). These elements might potentially accumulate to larger amounts in the leaves of plants after being taken up from the soil. Thus, frequent monitoring of these elements is critically important. METHODS The present study intended to determine PTEs (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) in both tea leaves and infusions using ICP-OES. Various multivariate data analysis methods such as principal component analysis (PCA) and hierarchical cluster analysis (HCA) were employed to elucidate the potential sources of PTEs contamination, whether from anthropogenic activities or natural origins. Additionally, Pearson's correlation coefficient (PCC) was calculated to assess the relationships between the variables under study. RESULTS The mean contents (mg/L) of all studied elements in tea infusions decreased in order Mn (150.59 ± 1.66) > Fe (11.39 ± 0.99) > Zn (6.62 ± 0.89) > Cu (5.86 ± 0.62) > Co (3.25 ± 0.64) > Ni (1.69 ± 0.23) > Pb (1.08 ± 0.16) > Cr (0.57 ± 0.09) > Cd (0.46 ± 0.09) > Al (0.05 ± 0.008), indicating that Mn exhibits the highest abundance. The mean concentration trend in tea leaf samples mirrored that of infusions, albeit with higher concentrations of PTEs in the former. The tolerable dietary intake (TDI) value for Ni and provisional tolerable monthly intake (PTMI) value for Cd surpassed the standards set by the WHO and EFSA. Calculated hazard index (HI < 1) and cumulative cancer risk (CCR) values suggest negligible exposure risk. CONCLUSION Elevated levels of PTEs in commonly consumed tea products concern the public and regulatory agencies.

Exposure Assessment of Essential and Potentially Toxic Metals in Wheat-Based Sweets for Human Consumption: Multivariate Analysis and Risk Evaluation Studies. Molecules 2023; 28:7365. [PMID: 37959786 PMCID: PMC10650165 DOI: 10.3390/molecules28217365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 10/25/2023] [Accepted: 10/25/2023] [Indexed: 11/15/2023] Open
Abstract
In recent years, there has been a growing concern about the negative impact of unforeseen contaminants such as metals in commonly consumed food items, which pose a threat to human well-being. Therefore, it is of utmost importance to evaluate the levels of these contaminants to guarantee the safe consumption of these food items. The goal of the current research is to determine the levels of essential (EMs: Mg, Ca, Mn, Fe, Co, Cu, and Zn) and potentially toxic metals (PTMs: Al, Cr, Ni, As, Cd, and Pb) in various brands of wheat-based sweets. One hundred samples were collected and analysed via flame atomic absorption spectrometry (FAAS) and inductively coupled plasma-optical emission spectrometry (ICP-OES). Also, the current study was to investigate the distribution, correlation, and multivariate analysis of 13 metals (Mg, Ca, Mn, Fe, Co, Cu, Zn, Al, Cr, Ni, As, Cd, and Pb). Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were used to interpret the metals' association. The concentration (mg/kg) ranges of EMs were, in order, Mg (12.70-65.67), Ca (24.02-209.12), Mn (1.32-9.61), Fe (4.55-111.23), Co (0.32-8.94), Cu (2.12-8.61), and Zn (2.60-19.36), while the concentration (mg/kg) ranges of PTMs were, in order, Al (0.32-0.87), Cr (0.17-5.74), Ni (0.36-1.54), Cd (0.16-0.56), and Pb (0.14-0.92), and As was not detected in any sample under investigation. The HCA data revealed that Co, Al, and Ni form clusters with other metals. Sweets are prepared at high temperatures, and the elevated temperatures can increase the likelihood of Ni and Al leaching from stainless steel. Tolerable dietary intake (TDI) values for Ni were higher than the values established by the European Food Safety Authority (EFSA). The CR value found for the Ni and Cr was at the threshold level of cancer risk, if an amount of 25 g were to be used over a lifetime. In a nutshell, this study highlights the monitoring of EM and PTM levels in wheat-based sweets, and from a food safety perspective, the study is important for consumers of wheat-based sweets.
