Arsenic (As) is one of the most harmful chemical elements known to man and to the environment, mainly due its high toxicity and wide distribution; the content of this element within the soils is a genuine concern, thus making it paramount to know its natural contents in a regional context. The present study aimed to determine the natural Arsenic content in the A horizon of 31 soil profiles from the state of Santa Catarina, Brazil, which is useful in determining reference values, monitoring, remediation of contaminated areas, legal regulation and Brazilian laws. Soil samples were prepared following the USPEA 3051A SW-846 method and were previously chemically reduced from As(V) to AS(III) by using the BCR method. The determination was performed in an Inductively Coupled Plasma - Optical Emission Spectrometry - Hydride Generation (ICP-OES-HG at cold vapor). Results obtained from the soil groups reveal the materials of basaltic origins as the ones with more As content while those of sediment origins had lesser content. Evaluated soil profiles fit into the following descending order regarding their As content: Latossolos, according to EMBRAPA (Oxisols according to Soil Taxonomy) > Nitossolo (Ultisols, Oxisols (Kandic), Alfisols) > Chernossolos (---) = Cambissolo (Inceptisols) = Argissolo (Ultisols) > Neossolos (Entisols). Keywords: arsenic content, reference value, soils, trace element.

The aim of this study was to investigate the distribution of chemical elements in topsoil and subsoil, focusing on the identification of natural and anthropogenic element sources in the area of the Crn Drim River Basin, Republic of Macedonia. For that purpose, by using sampling network of 5 × 5 km, 124 soil samples from 62 locations (topsoil and bottom soil) were collected. In total 60 elements were analysed, from which 18 elements (Ag, Al, B, Ba, Ca, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, V и Zn) were analysed by inductively coupled plasma - atomic emission spectrometry (ICP-AES) and an additional 42 elements were analysed by ICP - mass spectrometry (ICP-MS). Multivariate statistical analysis was applied to the obtained data. Factor analysis applied to the ICP-AES results produced four geogenic fac-tors: F1 (Ba and K); F2 (Ag, Cd, Cu, Ni, Pb and Zn), F3 (Cr, Fe, Na, Ni and V) and F4 (Al, Ca, Mg and Mn). Data ob-tained from the distribution maps and data analysis on soil samples, indicate the natural occurrence of the analysed ele-ments as well as low concentrations of heavy metals in the studied area.

Abstract: Saffron is one of the most expensive spices in the world, and its popularity as a tasty food additive is spreading rapidly through many cultures and cuisines. Minerals and heavy metals are minor components found in saffron, which play a key role in the identification of the geographical origin, quality control, and food traceability, while they also affect human health. The chemical elements in saffron are measured using various analytical methods, such as techniques based on spectrometry or spectroscopy, including atomic emission spectrometry, atomic absorption spectrometry, inductively coupled plasma optical emission spectrometry, and inductively coupled plasma mass spectrometry. The present study aimed to review the published articles about heavy metals and minerals in saffron across the world. To date, 64 chemical elements have been found in different types of saffron, which could be divided into three groups of macro-elements, trace elements, and heavy metals (trace elements with a lower gravity/greater than five times that of water and other inorganic sources). Furthermore, the chemical elements in the saffron samples of different countries have a wide range of concentrations. These differences may be affected by geographical condition such as physicochemical properties of the soil, weather and other environmental conditions like saffron cultivation and its genotype.

Surface Water Samples

An investigation of the distribution of 23 chemical elements (Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sr, V and Zn) in surface water samples from the entire basin of the Crna River, Republic of Macedonia, was carried out. In total 31 water samples were collected, from which 8 samples from the Crna River and 4 samples from four main tributaries of Crna River in the Pelagonia Valley (Blato, Prilepska Reka, Dragor and Jelaška Reka). Also, surface water samples were collected from 3 locations in the Tikveš Lake, 8 locations from the Majdanska River and river of Blašnica before its inflow into the Tikveš Lake and from 7 locations of the lower course of the Crna River after the dam of Tikveš Lake until its inflow into the river of Vardar. Determination of the concen-tration of the investigated elements was performed by using atomic emission spectrometry with inductively coupled plasma (ICP-AES). All data obtained for the analyzed samples were statistically processed using software Stat Soft 11.0 where the descriptive statistical analysis of the value for the concentration of the elements was performed. The maps of spatial distribution of the concentration for each element and a histograms for the representation of elements with mean values of the concentrations by regions, were also prepared. The obtained results show that the concentration of investigated element are mainly followed the lithology of the region. However, higher concentrations of arsenic were found in the water samples from the river of Blašnica which is a result of anthropogenic influence from the abounded Allchar mine on the Kožuf Mountain. Also, the increased concentrations of nickel were found in the samples from the lower couse of the Crna River after the dam of Tikveš Lake due to the anthropogenic influence from the ferronickel smelter plant Feni Industry, which can influence the quality parameters of surface waters.

Although, the safe limits of human daily boron (B) exposure are not absolutely clear, there is a growing interest in B and its effects on human health. The aim of the present study was to estimate daily B exposure in 66 males in Turkey living in a B-rich area using water containing at least 2 mg/l boron, with an average age of 38·55 (se 1·66) years and an average number of years of residence in the B-rich area of 35·89 (se 1·73). Another group of males (n 57), living in the city centres of Balıkesir and Ankara, were taken as controls; the average age and number of years of residence for this group were 29·44 (se 1·43) and 10·26 (se 1·83) years, respectively. As it is assumed that the B level in urine reflects daily B exposure, the amount of urinary B of both the study and control groups was analysed by using an inductively coupled plasma optical emission spectrometry (ICP-OES) technique. The average daily B exposure value was calculated as 6·77 (se 0·47) mg in the study group and 1·26 (se 0·1) mg in the controls. The results of this study are expected to contribute to creating a reference value for a safe daily B exposure.

Generally speaking, ceramic materials are insensitive to corrosion, compared to most other materials. The present study questions the fact that ceramics are inert. Two major aspects are to be considered: the stability of zirconia over time, the stable tetragonal phase transforming into an unstable monoclinic form; the multitude of manufacturing methods, using various additives, sintering additives, oxides mixing, impurities, grain boundaries, and porosities which strongly influence the corrosion behavior and chemical degradation. In case of the investigated ceramics two paths were pursued:a) Dissolutions of ceramics in a mixture of HNO3 60% and HF 40% ultrapure medium.b) Release of cations from ceramics in various mediums:dental bioceramics in a 0.07 M HCl medium and a 0.1% NaF+0.1% KF medium; ceramics used in jewelry and watchmaking applications in a HCl 0.07 M medium and an artificial sweat medium. By inductively coupled plasma-optical emission spectrometry/mass spectrometry (ICP-OES/MS), traces of significant chemical elements were assessed: Hf, Cr, Y, As, Pb, Al, Fe, Cu, Se, Sb, La, Ni, Co, Sb, Ta, Te, Ba, Sm, Nb, Hg, Cd, Sr, As and Se. In ceramics used in jewelry and watchmaking applications the concentrations found vary from one ceramic to another, including toxic elements such as Te, Ba, As, Pb, Sm, Hg and Cd, therefore being technical zirconia ceramics which are not intended for the medical field. For ceramics used in jewelry and watchmaking applications a screening identification test for Ni, Co, Cu and Fe with strips of type Merckoquant® (Merck, Kenilworth, NJ, USA) was also performed. The obtained data prove that the zirconia ceramics in question are far from being “inert”.

Methodology for the determination of total As in crispbread by hydride generation inductively coupled plasma optical emission spectrometry (HG–ICP–OES) was evaluated. The effect of pre-reduction reagents before the HG reaction under conditions of real samples was investigated. Sonication (15 min, 25°C) of samples with aqua regia allowed complete release of As species in solutions. Arsenic hydride was generated in the reaction with NaBH4 (1.0 % (m/v)) after the pre-reduction of AsV to AsIII with ascorbic acid (1.5 % (m/v)) and KI (0.5 % (m/v)) in 3 mol L–1 HCl. Detection limits (LODs) of 0.46 (AsIII) and 0.49 (AsV) μg L–1 were assessed. The accuracy of the method was confirmed by analysis with a certificate reference material and recovery test. Various crispbreads (wheat, rye, corn, rice) were analysed with the developed procedure and As content varied between 0.027 and 0.219 μg g–1, being the highest in the rice samples.

The presented results expand the understanding of the normal chemical composition of the body. The study was carried out on the basis of a pig-breeding farm in the Altai Territory in 2016-2020 on clinically healthy 6-month-old pigs of the Landrace breed. Chemical analysis of pig bristles was performed by inductively coupled plasma atomic emission spectrometry. The data were processed using Statistica 8 software (StatSoft Inc., USA). A study of the correlations between phosphorus in bristles and other macro-, microelements, as well as chemical elements associated with phosphorus, has been carried out. Only positive connections of different strengths have been established between phosphorus and elements involved in the formation of bone tissue (calcium, magnesium, manganese), copper, iron and strontium. There are two groups of direct interactions of different strengths between the chemical elements associated with phosphorus. Explained supposedly the essence of the connections, which is consistent in the bristle, as the final site of exchange, with organs and tissues of mammals.

Baseline Concentrations

This study intends to evaluate baseline concentrations of chemical elements for unpolluted sediments of Sepetiba Bay (SE Brazil). It analyzes the concentrations of potentially toxic elements (PTE) and other chemical elements (by Inductively Coupled Plasma Mass Spectrometry and Inductively Coupled Plasma Emission Spectrometry) from the upper part of the SP2 drillcore (or 2-SPT-1-RJ; with 50.30 m length), collected on the margins of Sepetiba Bay (at latitude 22° 55'S and longitude 43° 46'W). This core was described and sampled. Textural, mineralogical and geochemical analyses were performed in 17 sediment levels. The sediment layers of interest were selected, considering the period in which they were deposited, before high anthropic influence in the area, and on sediment grain-size. Only the muddy levels were selected, since fine sediments generally tend to have higher elemental concentrations. Foraminiferal occurrence was also analyzed in the selected layers. The results indicate that the studied sediments were deposited in a transitional marine context, after being exposed to multiple sedimentary cycles and weathering. The baseline concentrations, related to natural sediment sources were estimated for As, Cd, Co, Cr, Cu, Ni, Pb, Zn) and P and for other chemical elements. These results are useful in environmental impact assessment not only in the study area, but also for other coastal regions of Rio de Janeiro State. TÍTULO: CONCENTRAÇÕES DE FUNDO DE ELEMENTOS QUÍMICOS NA BAÍA DE SEPETIBA (SE BRASIL) RESUMO:Este estudo pretende avaliar as concentrações de fundo de elementos químicos, em sedimentos não poluídos, na Baía de Sepetiba (Se Brasil). Analisa as concentrações de elementos potencialmente tóxicos (PTE) e outros elementos químicos (por Espectrometria de Massa Plasma Acoplada Indutivamente e Espectrometria de Emissão Plasma Acoplada Indutivamente) da parte superior do testemunho SP2 (ou 2-SPT-1 RJ; com 50,30 m de comprimento), coletado nas margens da Baía de Sepetiba (à latitude 22° 55'S e longitude 43° 46'W). Este testemunho foi descrito e amostrado a cada 5 cm. Análises estruturais, mineralógicas e geoquímicas foram realizadas em 17 níveis de sedimentos. Os níveis de interesse foram selecionados, considerando o período em que foram depositados, antes da alta influência antrópica na área, e no tamanho do grão do sedimento. Apenas os níveis de lama foram selecionados, uma vez que os sedimentos finos tendem geralmente a ter maiores concentrações de elementos quimicos. A ocorrência de foraminíferos foi também analisada nas camadas selecionadas. Os resultados indicam que os sedimentos estudados foram depositados num contexto marinho de transição, após serem expostos a múltiplos ciclos sedimentares e a intemperismo. As concentrações de fundo, relacionadas a fontes naturais de sedimento foram estimadas para As, Cd, Co, Cr, Cu, Ni, Pb, Zn) e P e para outros elementos químicos. Esses resultados são úteis para a avaliação de impacto ambiental, não apenas na área de estudo, mas também em outras regiões costeiras do Estado do Rio de Janeiro. PALAVRAS-CHAVE: Multi-indicadores.
