“…Cr concentrations of up to 4000 ppm are predicted in soils derived from igneous rocks, i.e., ultramafic rocks, while Cr concentrations of up to roughly 11 ppm are expected in sedimentary rocks [61]. The permitted limits for Zn, Ba, Ni, Cu, and Cr in drinking water are 5 ppm, 0.7 ppm, 0.02 ppm, and 0.05 ppm, respectively, as determined by Karasakal [62] (Table 3). This indicates that the average concentrations of Zn, Ba, Ni, Cu, and Cr in the examined sections that were looked at are higher than the acceptable limits set by US-EPA (1978) and Pakistan-EPA (1978).…”

The geochemical investigation of shales from the Early to Middle Cretaceous Chichali Formation in the Hazara Basin was conducted to determine the origin, tectonic setting and evolution, paleo-weathering conditions, and paleo-oceanographic reconstruction. The research included a comprehensive field survey, sample collection, and analysis of a variety of main, trace, and rare-earth elements using an X-ray fluorescence spectrometer (XRF). Bivariate plots and ternary diagrams were used to determine the provenance, tectonic setting, and paleo-weathering conditions that existed during the development of the Chichali Formation in the Hazara Basin. The values of Ba/Sc, Ba/Co, Th/Sc, Cr/Th, Cr/Zr, Th/Co, Th/Cr, Sc/Th, bivariate plots of Al2O3 vs. TiO2, TiO2 vs. Zr, TiO2 vs. Ni, Df1–Df2, Zr vs. Nb, and La/Sc vs. Th/Co, and ternary diagram of K2O–Fe2O3–Al2O3 were used to illustrate the passive continental margin setting of Chichali Formation shales. The detailed chemical analysis also provides an understanding of the marine geochemical cycle, which reflects the origin of these sediments. The average K2O/Al2O3 value is less than 0.4, indicating that the shale contains clay minerals. The Chichali Formation’s Chemical Index of Alteration (mean = 71) and Index of Compositional Variation (mean = 1.12) values show a modest degree of chemical weathering in the source locations. From an environmental standpoint, the Chichali Formation is richer in toxic elements such as Ba, Zn, Ni, Cr, and Cu, which may be damaging to agricultural soils and drinking water when present in excess. These metals are incorporated into the formation during the weathering process.

“…Among the different spectroscopic techniques that are used for the elemental analysis of food samples are flame atomic absorption spectrometry (FAAS), electrothermal atomic absorption spectroscopy (ETAAS), cold vapor atomic absorption spectroscopy (CV-AAS), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS) [1,8,9]. Until now, ICP-AES has been found to be a powerful analytical instrument for the assessment of the elemental composition of a wide variety of food and beverages samples, including fruits and vegetables [10], legumes [11], savory snack products [8], coffee [12], alcoholic drinks [13], milks [12], vegan milks and oils [14], rice [15,16], cereals [16], nuts and seeds [17], fruit juices [18], seaweeds [19,20], etc.…”

In this study, we present the development and validation of an inductively coupled plasma-atomic emission spectrometric (ICP-AES) method for the determination of Ag, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb and Zn in different candies. Various wet digestion protocols were examined in order to ensure minimum consumption of chemicals and sample preparation time. Under optimized conditions, less than 10 min were required for complete sample decomposition. The ICP-AES method was validated in terms of linearity, accuracy, precision, limits of detection (LODs) and limits of quantification (LOQs). The relative recoveries for the proposed method ranged between 80.0% and 119.0%, while the relative standard deviation values were lower than 9.0%, indicating good method accuracy and precision, respectively. The LODs for the examined analytes were 0.04–2.25 mg kg−1. Finally, the proposed method was successfully employed for the analysis of hard candies, jellies and lollipops that are sold in the Greek market, which are highly likely to be consumed by children.

“…Estas actividades contaminan el suelo (Ashraf y col., 2019), el agua y el aire; y eventualmente llegan a personas y animales a través de la cadena alimentaria. Por lo tanto, esta contaminación perjudica enormemente la salud de los consumidores (Karasakal, 2020). Actualmente, esta contaminación se mide mediante el uso de biomonitoreo, dentro del cual la vigilancia de los productos animales desempeña un papel importante (Scaramozzino y col., 2019).…”

La evaluación de metales pesados en leche puede considerarse como indicador de contaminación ambiental de un lugar, por lo que el objetivo de la investigación fue determinar la presencia de Plomo, Mercurio y Arsénico en leche cruda de Machachi, Provincia de Pichincha-Ecuador. Se recolectaron 58 muestras provenientes de 29 fincas lecheras con sistema de pastoreo extensivo y ubicadas hasta máximo un kilómetro a la redonda del Municipio de Machachi, donde existe actividad industrial y está cerca de la Panamericana Sur. Las muestras fueron analizadas mediante la técnica de espectrofotometría de absorción atómica por generador de hidruros (Mercurio y Arsénico) y con horno de grafito (Plomo). Todas las muestras analizadas mostraron niveles de Plomo, con una media de 0.208 mg/kg (rango entre 0.0016 a 0.719 mg/kg), de las cuales el 98.28% (57/58) contienen niveles superiores a los máximos permitidos por la NTE INEN 9 de 0.02 mg/kg. También se detectó Mercurio en cuatro muestras (media de 0.00009 mg/kg, rango entre 0.00 a 0.002 mg/kg) y Arsénico en dos muestras (media de 0.00003 mg/kg, rango 0.00 a 0.001 mg/kg), sin embargo, las mismas estuvieron por debajo del límite permitido por el Codex Alimentarius (0.01 mg/kg) en alimentos en general. Con los resultados obtenidos, se concluye que podría existir un área contaminada con Pb, por lo que se debe realizar un monitoreo continuo en leche, y ampliar la investigación a las posibles fuentes de contaminación, como agua de bebida, agua de riego, forrajes y alimentos que reciben las vacas lecheras de la zona.
