Risks and benefits associated with the consumption of three species of fish native to the Brazilian Amazon

In the Brazilian Amazon, fish is part of the diet and culture of the native population. With industrialization and the pollution of rivers, the number of cases of people contaminated by toxic pollutants present in fish has grown. Therefore, the objective of this study was to analyze three species of fish from the Amazon, the curimatã, pescada-gó, and piramutaba, to investigate the risks and benefits associated with the consumption of their muscles and livers in different seasonal periods. The amino acid and fatty acid profiles were investigated by liquid and gas chromatography, respectively. The essential elements (Cu, Fe, Mg, Na, and Zn) were quantified by flame atomic emission spectrometry, and the contaminants lead (Pb) and mercury (Hg) by flame atomic emission spectrometry and graphite furnace. Significant amounts of unsaturated fatty acids were found in muscle and liver. The polyunsaturated acids were more present in the pescada-gó and the monounsaturated in the curimatã. Contaminants (Pb and Hg) were found at levels higher than the limit allowed by Brazilian legislation. The curimatã species contributed more than 131.79% of the Hg, exceeding the tolerable weekly limit, and is considered unfit for consumption. The study demonstrated that constant biomonitoring of species traded in the region is necessary to ensure food security.

Analysis of Sodium Levels in Different Brands of Edible Salts by Flame Photometer

Sodium is a key element for all living things, mainly animals, some plant species, and humans. In animals, sodium ions are necessary for the regulation of blood and body fluids, the transmission of nerve impulses, heart activity, and certain metabolic functions. Sodium is the chief cation in the extracellular compartment of an animal body. Sodium plays a vital role not only in the human body but also in various food types. Salt, also known as sodium chloride, is about 40% sodium and 60% chloride. It flavors food and is used as a binder and stabilizer. The sodium content in different brands of edible salts can be analyzed using flame photometry. Flame photometry, also called flame atomic emission spectrometry, is a branch of atomic spectroscopy in which the species examined in the spectrometer are in the form of atoms. The samples used for analysis are junk foods, which have become a common trend among all generations. A total of 13 brands were analyzed for iodine content. From that, two commonly used brands were selected and analyzed for estimating the sodium and potassium contents in them by flame photometry. The analysis helps in creating awareness among all generations to reduce the sodium intake in order to prevent problems like hypertension, hyponatremia, hypernatremia, and associated medical complications in the future.

Determination of Caffeine and Few Metals in Halabja Tea and Comparing with Various Tea Samples in Erbil Markets

This paper deals with two main parts: part (I) performed the caffeine levels evaluation in three commercial tea leaves (black, green, and herbal tea) in Erbil markets and Halabja city. The caffeine was extracted by liquid-liquid extraction using dichloromethane and chloroform solvents. The extracted caffeine was purified, and then identified by melting point (M.P), ultraviolet (UV) and Fourier transform infrared (FT-IR) spectroscopy that provides spectra identical to the standard caffeine crystals. The level of caffeine in black tea was found greater than in green tea, presumably because black tea are made of older tea leaves, in contrast, there is no caffeine obtained from Halabja tea. Part (II) mentioned the determination of metal ions (lithium, sodium, potassium, and calcium) in 5 brands of black and green tea (leaves and bags) in addition to Halabja tea; using flame atomic emission (FAES) and flame atomic absorption (FAAS) spectroscopy. The tea beverages were prepared by three different methods: (chemically, infusion, and continuous infusion). There was a moderate quantity of sodium, potassium, and calcium was determined in the 5 brands of tea, while lithium found in the trace. Halabja tea was free from caffeine while lithium, sodium, potassium, and calcium elements of the Halabja herbal tea are all higher than all the other types of tea leaves and bags

There are bentonites with different composition: sodium, calcium, sodium-calcium, activated calcium, as well as mixtures between natural calcium and activated calcium. Their capacity to transfer elements from and to a model solution with wine parameters have been investigated. Inductively coupled plasma-optical emission spectrometry (ICP-OES), inductively coupled plasma with mass spectrometry (ICP-MS), flame atomic emission spectrometry (FAES) and flame atomic absorption spectrometry (FAAS) techniques have been used. The selected elements, which are subject to this study, are important for human health as well as for the stability of wine clarity.

The choice of methods for lithium and boron determination in lithium-boron alloys

A lithium-boron alloy (LBA) with a high lithium content (up to 70%) is used as an anode material for molten salt batteries in chemical sources of current. We present a complex of developed techniques for determining mass fractions of free lithium, total lithium, and total boron in lithium-boron alloys containing lithium mass fractions no more than 70%, boron mass fractions — no less than 26%. Optimal conditions for preparation of LBA samples and subsequent free lithium extraction from them are determined. The developed techniques are intended for i) extraction-titrimetric determination of free lithium in a content range of 20 - 50% (the relative total error no more than 1.1%); ii) determination of the total lithium content using flame atomic emission spectrometry in a content range of 59.0 - 96.0% (the relative overall error no more than 2.7%; iii) determination of the total boron content by two methods, i.e., potentiometric titration within a content range of 5 - 40% (the relative total error no more than 1.3%) and flame atomic absorption spectrometry within a content range of 4.9-50.7% (the relative total error no more than 4.9%). The results of analysis of full-scale LBA samples for the content of free lithium, total lithium and total boron are presented. It is shown that the application of two techniques for the determination of total boron content in lithium-boron alloys makes it possible to get the convergent results within the limits of measurement errors. The developed techniques are certified by the metrological service of the enterprise and can be used for the incoming and process control of the LBA production.

Nuts as a Dietary Enrichment with Selected Minerals—Content Assessment Supported by Chemometric Analysis

Nuts used as a snack and meal accompaniment supply plant protein and fatty acids that are beneficial for human health; however, they can also provide minerals. The aim of this study was to determine the content of selected elements that are often deficient in the diet (calcium, potassium, magnesium, selenium, and zinc) in nuts and determine whether they can be used to supplement deficiencies in the diet. In this study, we analyzed 10 types of nuts (n = 120 samples) that are consumed and available for sale in Poland. The content of calcium, magnesium, selenium, and zinc was determined by the atomic absorption spectrometry method, and flame atomic emission spectrometry was used for determination of potassium contents. The highest median calcium content was found in almonds (2825.8 mg/kg), the highest potassium content in pistachio nuts (15,730.5 mg/kg), the highest magnesium and selenium contents in Brazil nuts (10,509.2 mg/kg and 4348.7 μg/kg, respectively), and the highest zinc content in pine nuts (72.4 mg/kg). All the tested nuts are a source of magnesium, eight types of tested nuts are a source of potassium, six nut types are a source of zinc, and four nut types are a source of selenium; however, among the tested nuts, only almonds can be considered a source of calcium. Moreover, we found that selected chemometric methods can be useful in the classification of nuts. The studied nuts are valuable products that can be used to supplement the diet with selected minerals and can therefore be labelled as functional products crucial for disease prevention.

Calcium release from eggshell by nutrient-solubilizing bacteria

Eggshell is a nutrient-rich residue and can be used as a soil amendment and fertilizer. However, it has a slow release, making its use unfeasible, but microorganisms can accelerate the process of nutrient release. Based on this, the objective was to evaluate the solubilization of the eggshell in the culture medium and in the soil by bacterial strains. Two experiments were installed in a completely randomized design, which consisted of 13 treatments, 12 bacterial strains and a control experiment without inoculation. The first experiment was carried out in a 13 x 2 factorial scheme with minimal medium containing eggshell or CaCl2 with four replications. The media were incubated at 28 °C and after three and seven days the growth, the pH of the medium and the concentration of soluble Ca2+ were evaluated by flame atomic emission spectrometry. The second experiment was carried out in plastic flasks in which 175 g of soil and 0.75 g of eggshell were inserted. After incubation, the pH in CaCl2, the potential acidity (H + Al) and the concentration of K+, Ca2+ and Mg2+ were evaluated. In the final analysis, the bacterial strains did not change the pH and Ca2+ values ​​of the culture medium in the in vitro experiment. In the soil experiment, strains 100-40 and 100-5 showed the ability to solubilize eggshell calcium.

Nutrient composition and physical properties of citron watermelon (Citrullus lanatus var. citroides (L.H. Bailey) Mansf. ex Greb.) seeds are related to seed coat visual appearance

Roasted citron watermelon seeds are eaten as snacks based on maturity indices. Association between coat colour, nutrient composition and physical properties is unknown. Therefore, seed coat thickness (SCT), hardness and popping yield (PY) may influence roasting quality and chewability. Understanding seed nutrient composition, physical properties, and coat colour associations allows selection for desirable traits. Forty accessions were analysed for mineral elements using flame atomic emission spectrometry (FAES) for K and flame atomic absorption spectrometry (FAAS) for Mg, Cu, Mn, and Zn. Physical properties such as (seed thickness (ST), weight required to crack seed (WRCS), SCT, and PY were analysed. Data was subjected to correlation and Principal Component Analysis. Significant differences were observed for mineral elements and physical properties (P < 0.05). Dark and red seeds had high ST and SCT but low WRCS, Cu and Zn compared to brown seeds. Significantly lower PY and high Ca content were recorded for dark seeds. Dark seeds had high hemicellulose (19.58%), cellulose (39.17%) and lignin (30.08%). Popping yield was positively correlated with lightness (r = 0.72; P < 0.001) and negatively correlated with Ca (r = -0.77; P < 0.001). Seeds with lighter colours had higher popping yield and less Ca, implying that coat colour influences palatability, nutrient composition and physical properties. Study findings will guide breeding strategies to enhance the nutritive value of seeds.

Multivariate optimization of a goat meat alkaline solubilization procedure using tetramethylammonium hydroxide for metals determination using FAAS

In the present work, multivariate designs were used to optimize an alkaline dissolution, assisted by ultrasound energy, procedure of goat meat using tetramethylammonium hydroxide (TMAH) aiming to determine Ca, Cu, Fe, K, Mg, Na and Zn by flame atomic absorption (FAAS) and emission (FAES) spectrometry. The optimal conditions found for the dissolution were in the following ranges: 0.4–0.5 g for the sample mass, 12–15 min of sonication and using 700–1000 µL of 25% TMAH at a temperature of 50 °C. The obtained limits of quantification varied between 0.221 (Mg) and 7.60 (Ca) μg g−1. Accuracy was assessed by comparing the results obtained by applying the proposed method with the digestion in an acid medium using a digesting block and by analyzing bovine liver certified reference material. The application of a t-test revealed that, at a 95% confidence level, there were no significant differences between the values obtained.

Results accuracy of the simultaneous Na, K, Li, Rb and Cs determination in geochemical objects using the flame atomic emission spectrometry

One of the most important challenges in the simultaneous determination of the five alkaline elements is that their abundance differs thousands of times in natural samples. Therefore, usually the analysis of the same samples is performed using several analytical methods or techniques. An atomic emission spectrometry is the most selective method for the determination of alkaline elements in wide ranges of their contents. The reliable and correct simultaneous determination of major and trace elements contents by one method is economically attractive for classifying rocks, reconstructing the conditions of their formation, etc. The atomic emission spectrometry technique of the simultaneous determination of the five alkaline elements was developed with the use of the modern equipment. The accuracy and trueness of the developed technique results were evaluated in the current study. The technique features were the preparation and the analysis of the high-salt solutions of the geochemical samples, and the use of a low-temperature propane-butane flame and multichannel photoelectric recording of the spectra for the simultaneous determination of alkali metals contents. A specific data processing ensured accounting for the spectral background and minimizing the interferences when calibrating by CRMs with various compositions and genesis. The determined concentrations ranges of alkaline elements in natural and man-made environments had been expanded by improving the detection limits and using several analytical lines of Na, K and Rb with different spectral features. FAES results were compared with the results of XRF, ICP-MS, the standard addition and dilution methods, and its accuracy and trueness were found to be satisfactory for the requirements of geological and geochemical studies.

Analytical methods assessment for exchangeable cations analysis in soil: MIP OES appraisement

ABSTRACT Soil monitoring and research often requires a comparison of laboratory data generated by diverse instruments and in different laboratories to demonstrate the reliability and accuracy of the results. The outcomes of this work highlight a performance comparison among different analytical methods for the determination of calcium (Ca), magnesium (Mg), sodium (Na), and potassium (K), in soil. Five soil samples were used for analytical methods comparison, corresponding to an argentine agricultural soil interlaboratory, and four soil samples from the Pampa region of Argentina were used for analytical application of the instrumental methods. The results obtained with flame atomic absorption and emission spectrometry (FAAS-FAES) and microwave-induced plasma optical emission spectrometry (MIP OES) were compared to those obtained by conventional analytical methods as complexometric titration and flame photometry. As there were no significant differences between classical methods with instrumental ones, FAAS-FAES and MIP OES were validated following criteria based on international guidelines. Accuracy, precision, linearity, limits of detection and quantification, sensitivity, analytical sensitivity, and working range were evaluated. The results established the satisfactory performance of FAAS-FAES and MIP OES for exchangeable cations. MIP OES is an efficient alternative to FAAS-FAES, with wide linear dynamic range, which is advantageous concerning to the concentrations in which these exchangeable cations are found in soils, avoiding sample dilutions. The most remarkable advantage of MIP OES is the low running costs as it does not use flammable and toxic gases. Due to its benefits MIP OES could be recommended as the main analytical method for exchangeable cations determination.

Selected Toxic Heavy Metals Levels in Vegetables, Soil and Irrigation Water at Awashriver, Ginchi Town, West Shoa Zone, Ethiopia

The levels of selected heavy metals (Cr, Cd and Pb) have been determined in cabbage, onion, soil and Awash river used for irrigation have been investigated. The cabbage, onion, soil and Awash River water samples were collected from the farmlands around Ginchi Town of West Shoa Zone in which the Anmol Ethiopia PLC, a paper industry, were there. The samples were digested using properly optimized wet digestion procedures. The metal contents were analyzed using Flame Atomic Emission Spectroscopy (FAES). However, Cd and Pb were not detected in all samples. Likewise, the highest level in onion samples was, Cr(0.59 mg/L). High concentrations of Cr (71.85 mg/Kg) were detected in soil samples on which the Onion vegetable was gown, while the corresponding values of Cr detected in the Onion sample itself was 59.35 mg/Kg. The levels of selected metals in downstream water (after effluent from Anmol Production Ethiopia PLC is mixed with Awash River) samples used for irrigation. It can be concluded that, Cr in both soil onion and onion exceeded the FAO limit of maximum recommended level vegetable plant, so that the consumption of this Onion might cause hazards with respective to Cr and hence care must be taken.

Infrared enthalpymetric methods: A new, fast and simple alternative for sodium determination in food sauces

This work developed a new technique and an application of an existing approach to determine sodium in food sauces, involving enthalpimetric reactions in the infrared. Infrared Thermometric Titration (TT-IR) was utilized, with simple analyzers and low-cost measurement instruments for the acquisition of the surface temperature generated in the sodium precipitation reaction and development of software for the acquisition and processing of data using Raspberry Pi. The sodium was also quantified by Thermal Infrared Enthalpimetry (TIE), a recently developed technique. The rapid and simple quantification of sodium by the TT-IR and TIE showed the possibility of a selective reaction for sodium, using aluminum nitrate, potassium and ammonium fluoride in an acid medium, with reduction of the reagents and without the digestion step in the sample preparation. The results acquired through TT-IR and TIE corroborated the Flame Atomic Emission Spectrometry (FAES) with 96 to 103% and 95 to 102%, respectively.

Evaluation of trace element contamination usingArmadillo officinalisDuméril, 1816 (Crustacea, Isopoda) as a tool: An ultrastructural study

To estimate trace element bioaccumulation in Armadillo officinalis, specimens were collected from Ghar El Melh lagoon then exposed for 3 weeks in contaminated sediments with copper, zinc, and cadmium. From the first week until the end of the experiment, a decrease in A. officinalis growth related to the increase of Cd concentration in the sediment was recorded. However, a mass gain was highlighted under Cu and Zn exposures. At the end of experiment, body metal concentrations were measured using flame atomic emission spectrometry. Results of the bioaccumulation factor showed that the species could be considered as a macroconcentrator of copper (BAF > 2) and a deconcentrator of zinc (BAF < 2). Microscopy observations of hepatopancreas cells showed morphological and histological changes even at the lowest concentration. They consisted in the microvillus border destruction, lipid droplets modifications, trace element accumulation, and the condensation of the majority of cellular organelles. The degree of these alterations was found to be dose-dependent. Through these results, the isopod A. officinalis could be used as relevant monitor organisms for soil metal contamination.

Additivity of optical emissions applied to neodymium and praseodymium quantification in metallic didymium and (Nd,Pr)-Fe-B alloy samples by low-resolution atomic emission spectrometry: An evaluation of the mathematical approach used to solve spectral interferences

In this work, the effectiveness of a mathematical approach to solve the spectral interferences involved in the optical emission of two chemical species (neodymium and praseodymium) when using monochromators with low-resolution in atomic spectrometry is evaluated. Although recent technological advances have promoted spectrometers equipped with high-resolution monochromators, which have a great instrumental capability in the separation of nearby lines and consequently avoid spectral interferences, many laboratories still have old spectrometers installed with insufficient resolution to overcome such interferences. In order to evaluate a mathematical approach based on Lambert-Beer's Law, the optical emissions of neodymium and praseodymium were monitored on a low-resolution (200 pm) flame atomic emission spectrometry (F-AES). These two elements were strategically chosen as an application model because they exhibit similar physicochemical properties, joint occurrence in nature and because they are increasingly used in the manufacture of super-magnets, a material increasingly required by the high technology industry. The effectiveness of the mathematical approach was evaluated in three different ways: (i) by recovery of the analytes in synthetic mixtures containing known quantities of the species; (ii) by spike and recovery trials on a representative blend of dissolved samples and (iii) by comparing the results obtained with another analytical method: Inductively coupled plasma optical emission spectrometry (ICP-OES) with a higher spectral resolution. The results indicate the effectiveness of this simple mathematical approach, allow the “survival” of instruments equipped with low-resolution monochromators and demonstrate the applicability of this approach to spectral correction. In addition, this work contributes an analytical method for the quantification of neodymium and praseodymium in metallic alloy samples involved in the production of super-magnets, aiding in the strict quality control of these materials.

Seed mineral reserves and vigour of Bambara groundnut (Vigna subterranea L.) landraces differing in seed coat colour

A newly emerged seedling, given light and water, but no external source of minerals, uses its internal mineral nutrient reserves effectively for an early establishment. This research sought to investigate the influence of seed coat colour on the abundance of mineral elements in Bambara groundnut. Four landraces (G340A, Kazai, Kazuma, and Mana) varying in seed coat colour were analysed for differences in seed mineral composition using energy dispersive x-ray (EDX) analysis and atomic absorption spectrometry (AAS). Seeds were germinated at 10 °C and 25 °C, and various indices including, (1) mean emergence time, (2) mean germination rate, (3) coefficient of velocity of germination, and (4) final germination percentage (FGP) were calculated. The importance of seed mineral elements in the establishment of Bambara groundnut was examined by measuring root length (RL), shoot length (SL), shoot dry mass (SDM), and root dry mass (RDM). Plant tissue elemental analysis was done using flame atomic emission spectrometry (FAES) for K and flame atomic absorption spectrometry (FAAS) for Mg, Cu, Mn, and Zn. There were significant differences (P < 0.001) in mineral element content of dry seeds. G340A and Kazai had the highest and the lowest K, P, Mg, Mn, and Zn (11.65 gkg-1, 7.2 gkg-1, 2.33 gkg-1, 59.56 mgkg-1, and 44.42 mgkg-1), and (8.82 gkg-1, 4.75 gkg-1, 1.38 gkg-1, 48.9 mgkg-1, and 42.6 mgkg-1), respectively. Cold test germination indices were significantly different, the highest FGP was 73.3% in G340A and the lowest was 57.8% in Kazai. There were strong positive correlations between seed mineral concentration and plant growth parameters (p < 0.001). We concluded that (1) seed mineral concentration has a significant impact on the early establishment of Bambara groundnut and (2) the dark-coloured landraces (hue 8º) used in this study have the highest concentration of macro and micro elements compared to light coloured seeds (hue 38º).

New alternative to reduce sodium chloride in meat products: Sensory and microbiological evaluation

In this research, the effect of partial replacement of NaCl by Soda-Lo® salt microspheres (25% (W/W), 30% (W/W), and 50% (W/W)) on the sensory and microbiological properties of meat products such as cooked ham, turkey breast and Deli type sausages were evaluated. Content of sodium from these meat products was determined through atomic-flame emission spectroscopy. New formulations of these meat products were evaluated by a sensory trained panel, as well as studied microbiologically (shelf-life and pathogens). Significant reductions of sodium in these meat products were obtained when 50% (W/W) of NaCl was substituted by Soda-Lo®. Sodium reductions of 30.07% (W/W), 21.93% (W/W) and 10% (W/W) in cooked Deli type sausages, ham and turkey breast, respectively, in comparison with controls. Statistically differences significant (p < 0.05) among controls and replaced samples were not detected by trained sensory panelists. Statistically significant differences (p < 0.05) on the behavior of the native microflora and Salmonella Enteritidis, Staphylococcus aureus and Listeria monocytogenes in control and replaced samples for the different meat products were not found. Therefore, it is concluded that partial substitution of NaCl by Soda-Lo® in meat products could be a good alternative to reduce sodium concentrations and offer benefices to the health of consumers.
