“…Dry ashes (DA) formation was proposed by Abdhel-Rahman et al [25] to quantify Fe, Mn, Cd, Pb, Ni, Cr, and Cu by ICP/OES in milk derivatives, carbonated drinks, and juices, either bottled in plastic or in cans. Finally, Biata et al [42] developed a simple and fast UA/IL/DLLME method for the pre-concentration of Sn and Sb traces in beverages with further quantification by ICP/OES.…”

Recent Trends in the Analysis of Chemical Contaminants in Beverages

Chemical contaminants should not be present in beverages for human consumption, but could eventually be ingested by consumers as they may appear naturally from the environment or be produced by anthropogenic sources. These contaminants could belong to many different chemical sources, including heavy metals, amines, bisphenols, phthalates, pesticides, perfluorinated compounds, inks, ethyl carbamate, and others. It is well known that these hazardous chemicals in beverages can represent a severe threat by the potential risk of generating diseases to humans if no strict quality control is applied during beverages processing. This review compiles the most updated knowledge of the presence of potential contaminants in various types of beverages (both alcoholic and non-alcoholic), as well as in their containers, to prevent undesired migration. Special attention is given to the extraction and pre-concentration techniques applied to these samples, as well as to the analytical techniques necessary for the determination of chemicals with a potential contaminant effect. Finally, an overview of the current legislation is carried out, as well as future trends of research in this field.

“…Due to the fact that amines are not chromophores and their volatility is quite low, a derivatization step is needed [40][41][42]. It has been reported that these previous steps in the analytical procedure improve resolution in liquid chromatography methods [58][59][60][61].…”

“…A negligible amount of organic solvent is used for the extraction and pre-concentration of the sample before analysis [62][63][64][65][66][67][68][69][70]. Microextraction has different modes such as vortex-assisted liquid-liquid microextraction [71, 72], solid-phase microextraction (SPME) [73][74][75][76][77][78][79][80][81][82][83][84][85][86] and liquid-phase microextraction (LPME) [75,77,79,[87][88][89][90][91][92][93], Dispersive liquid-liquid microextraction (DLLME) [75,94], cloud point extraction, (CPE) [95][96][97][98][99], single-drop microextraction (SDME) [100], ionic liquid-based dispersive liquid-liquid microextraction (IL-DLLME) [101,102] dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFO) [103]. However, the recent trends involve the miniaturization of the conventional liquid-liquid extraction principle.…”

Supramolecular solvents (SUPRASs) have rapidly gained more attention as a potential substitute to organic solvents in the sample preparation and pre-concentration process. The essential properties of SUPRAS solvents (e.g., multiple binding sites, different polarity microenvironments, the opportunity to tailor their properties, etc.) these qualities offer numerous opportunities to advance innovative sample preparation and pre-treatment platforms compared to the traditional solvents. Among these qualities, certain importance is placed on theoretical and practical knowledge. That has assisted in making significant developments in SUPRAS that advance our understanding of the processes behind SUPRA'S formation. The SUPRA-solute interactions that drive extractions are explored in this context to develop knowledge-based extraction techniques. This review mainly focused on the significant application of supramolecular-based solvents (SUPRASs) in microextraction techniques.SUPRASs-based liquid-phase microextraction (LPME) is an excellent tool for extracting, simple preparation, and pre-concentration from complex environmental samples. SUPRASs-LPME has a wide range of applications for analysing food, environmental samples, pharmaceuticals, and biological samples.

“…Generally, those who usually drink large amounts of alcoholic beverages have higher element levels in their biological fluids than the average individuals 27,40 . A recent study reports the presence of tin dissolving in beverages due to the use of tinplate packages 41 . Moreover, alcohol causes neurological disorders and may mask symptoms of contamination by neurotoxic metals such as tin.…”

Spatial pattern of the environmental exposure to tin in the vicinity of an alloy industry in Volta Redonda, Rio de Janeiro State, Brazil

Despite being widely used in industry, the literature on tin and its effects in humans is scarce, especially regarding reference values in biological indicators such as blood and urine. Similarly, environmental limits are also rare. This study sought to assess the spatial distribution of hotspots in the environmental exposure to tin in the vicinity of an alloy industry in the south region of the state of Rio de Janeiro, Brazil. The study population consisted of 74 adults. Graphite furnace atomic absorption spectrometry determined tin in all samples. Households and points around the industry were georeferenced with the use of GPS to identify the most intense tin sites. Results of the first and second campaigns ranged from 0.022 to 0.153 and 0.003 to 0.445µg m-3 for the atmospheric air, whereas such ranges were 0.64 to 1.61 and 1.97 to 8.54µg m-2 for household dust, respectively. The mean tin concentration found in the blood of the population was 3.85 ± 1.57µg L-1. In urine the value was 3.56 ± 1.88µg L-1. The kernel map showed the highest spatial concentrations of tin in household dust in the eastern region of the industry. In the first sampling, atmospheric air samples presented the most elevated concentrations in the southwest and southeast. Although the direction of the wind was northwest, potentially high risks were concentrated in the central area in the second collection. The largest hotspots were in the north, south and southeast regions; however, urine samples showed medium to high levels in the west and east regions. Regarding blood samples, the greatest difference was the absence of hotspot areas in the west. Environmental monitoring becomes necessary to better assess the exposure to tin.
