Chemical Content

Bivalves are a good source of nutrients but also a potential source of environmental contaminants, which could pose a risk for consumers. The aims of this study were: the determination of 16 elements by ICP-MS in 48 samples of five bivalve species purchased from market in Korea; the identification of elements useful for species classification using multivariate analyses; and the benefit-risk evaluation associated to the consumption of these bivalves. The highest difference among content of elements between species was found for Cd, Mn, Ni, Zn, and Fe. Partial last squares discriminant analysis revealed elements with a VIP score >1 which were considered as the most relevant for explaining certain species. As, Cd, Co, and Ni were found as taxonomical markers of V. philippinarum; Mn, Zn, Mg, and Na of A. irradians; and Cd, Ni, and Fe of M. yessoensis. These species could serve as good dietary sources of essential elements. Cd exposure by consumption of Manila clams is not representing a health risk for the Korean population; however, through consumption of Yesso scallops, 5.3% of the Korean population has a potential health risk. Removal of the digestive gland before eating will drastically reduce the amount of Cd ingested.

Toxic element pollution is a serious global health concern that has been attracting considerable research. In this study, we elucidated the major routes of exposure to three toxic elements (mercury, cadmium, and lead) and two essential elements (manganese and selenium) through diet, soil, house dust, and indoor air and assessed the potential health risks from these elements on women from the coastal area of Miyagi prefecture, Japan. Twenty-four-hour duplicate diet, house dust, soil, and indoor air samples were collected from 37 participants. Cd, Pb, Mn, and Se concentrations were measured using inductively coupled plasma mass spectrometry, and Hg concentrations using cold vapor atomic absorption spectrometry. We found that soil and house dust were the primary reservoirs of these elements. Diet contributed most strongly to the daily intake of these elements, with mean values of 0.72, 0.25, 0.054, 47, and 0.94 μg/kg/day for Hg, Cd, Pb, Mn, and Se, respectively. The mean hazard quotient of Hg was 1.53, indicating a high potential health risk from Hg exposure in daily lives. The intakes of other elements were below the tolerable limits. Future studies with a larger sample size are warranted to confirm our findings.

Background. Most traditional medicines were prepared from plant origins. These plants could be contaminated by heavy metals, pesticides, and/or toxins. Therefore, the aim of the present study was to determine the level of heavy metals such as lead (Pb), cadmium (Cd), chromium (Cr), and copper (Cu) in frequently used traditional herbal preparations sold in Northeast Ethiopia and to estimate their health risks associated with their daily intake. Methods. A total of 6 traditional herbal preparations were randomly collected from local herbal shops of Dessie and Kombolcha town, Northeast Ethiopia. The samples were prepared for analysis by wet digestion method using nitric acid and hydrochloric acid treatment. The accuracy of the method was analyzed by the spike recovery test. Determination of Pb, Cd, Cr, and Cu by microwave plasma atomic emission spectroscopy was made in herbal preparations traditionally used in Dessie and Kombolcha town, Northeast Ethiopia. By calculating estimated daily intake (EDI), hazard quotients (HQ), and Hazard Index (HI) of metals, the health risk associated with the consumption of the analyzed herbal preparations was also evaluated. Results. The levels of heavy metals were in the range of 3.0–3.92 mg/kg for Pb, 5.35–10.7 mg/kg for Cr, and 0.815–12.3 mg/kg for Cu. However, cadmium was not detected in any of the traditional herbal preparations. This study revealed that the level of Pb and Cu in all analyzed samples was within the WHO maximum permissible limit of 10 mg/kg and 40 mg/kg, respectively. The level of Cr in all traditional herbal preparations was beyond the WHO maximum permissible limit (2 mg/kg). From the health point of view, the HQ value of Cr for KD-03 and KD-04 is greater than 1, suggesting potential health risk. Furthermore, the HI value had revealed that the consumption of KD-02, KD-03, and KD-04 samples had the potential of posing health risks to consumers over long-term consumption of herbal preparations. Conclusion. This study showed that most of the metal concentration levels in the herbal products were within the WHO maximum permissible limits. However, all samples had Cr levels above the WHO maximum permissible limit. Based on the results of this study, there would be a noncarcinogenic health risk to the consumer associated with the consumption of some herbal preparations marketed in Northeast Ethiopia.

Pre Treatment

The lack of interest in the determination of toxic elements in liquids for electronic cigarettes (e-liquids) has so far been reflected in the scarce number of accurate and validated analytical methods devoted to this aim. Since the strong matrix effects observed for e-liquids constitute an exciting analytical challenge, the main goal of this study was to develop and validate an ICP-MS method aimed to quantify 23 elements in 37 e-liquids of different flavors. Great attention has been paid to the critical phases of sample pre-treatment, as well as to the optimization of the ICP-MS conditions for each element and of the quantification. All samples exhibited a very low amount of the elements under investigation. Indeed, the sum of their average concentration was of ca. 0.6 mg kg−1. Toxic elements were always below a few tens of a μg per kg−1 and, very often, their amount was below the relevant quantification limits. Tobacco and tonic flavors showed the highest and the lowest concentration of elements, respectively. The most abundant elements came frequently from propylene glycol and vegetal glycerin, as confirmed by PCA. A proper choice of these substances could further decrease the elemental concentration in e-liquids, which are probably barely involved as potential sources of toxic elements inhaled by vapers.

The aim: The study aimed to assess the content of selected toxic compounds in mineral and spring waters available on the Polish market regarding potential health risks to consumers. Materials and methods: Selected mineral and spring waters available on the Polish market were the study’s objects. The content of such chemical compounds as arsenic, cadmium, lead, copper, and mercury in selected mineral and spring waters was analyzed. The content of metals in the samples was determined by inductively coupled plasma mass spectrometry (ICP-MS). Additionally, a literature review was performed to determine nitrates contamination of bottled waters available on the Polish market. Based on the collected data, an assessment of exposure and health risk to consumers was performed. Results: Arsenic had the highest mean concentration in the analyzed water samples. Consumption of such contaminated waters may be a significant health risk factor for consumers. Literature data indicate a relatively low content of nitrates in bottled waters available on the Polish market. Consumption of such mineral waters is not a significant source of exposure and does not translate into a significant health risk for consumers. Conclusions: To ensure consumers’ health safety, there is a need to monitor the content of potentially harmful compounds in mineral and spring waters available on the Polish market.

History Of

Ferns of the genus Pteridium are known to be responsible for cases of poisoning in cattle. The commonly found species of Pteridium in Brazil are P. arachnoideum and P. caudatum. The toxic principle of these ferns is ptaquiloside, a norsesquiterpene glucoside, which is a known carcinogen. Ptaquiloside can be secreted in the milk of cows grazing on bracken ferns, thereby posing a potential health risk for the milk consumers. The objective of the present study was to develop an analytical methodology using high performance liquid chromatography (HPLC) with ultraviolet (UV) detection to determine the concentrations of ptaquiloside in cow´s milk. HPLC-UV method, based on the conversion of ptaquiloside into pterosin B and its subsequent extraction using dichloromethane, was successfully developed for estimating concentrations of ptaquiloside in milk samples. However, the presence of ptaquiloside was not detected in milk samples obtained from cows with a history of bovine enzootic hematuria resulting from grazing on P. arachnoideum infested pastures in Brazil.

The method of inductive coupled plasma mass spectrometry (ICP-MS) was used for elemental analysis of alpaca hair. Various methods impact of hair sampling for analysis was evaluated with using deionized water and acetone. Sodium content decrease in the in hair samples washed with deionized water and Mg, Li, V, Ag, Cd, Ba level decrease in samples treated with acetone were found. The results can be explained by sodium attendance in the hair in the form of simple cations that are not bound to any organic compounds by strong bonds, while the results obtained for Mg, Li, V, Ag, Cd, Ba, suggest that the ions of these elements are connected with structural hair formations. Significant differences in the content of other macro- and microelements in alpaca hair treated with deionized water and acetone were not found.

The Difference

Previous studies have only focused on the bioaccessibility of single pesticide/metal without considering the potential impact of post-uptake interactions on bioaccessibility of pesticides/metals in the human digestive system. Hence, the influences of chromium (Cr) speciation on neonicotinoids bioaccessibility were investigated and the potential health risk based on the oral bioaccessibility was evaluated. Bioaccessibility of four neonicotinoids in apple and pear was measured using three common in vitro methods (SBRC, PBET, and IVG). Bioaccessibility of neonicotinoids in apple and pear varied between in vitro methods, which may reflect the difference of determination parameters (i.e., pH values, incubation time, and constituents). The neonicotinoids bioaccessibility was remarkably reduced by 17.21–81.21% and 11.61–73.70% with the addition of Cr(III) and Cr(VI), respectively. Risk assessment based on the hazard quotient (HQ) with bioaccessibility revealed that exposure to pesticide residues in the tested fruits were all below levels that might pose a health risk. These findings are of theoretical value for the safety evaluation of pesticide residues on food.
