“…PCA and HCA are multivariate analysis techniques commonly employed in the evaluation of food data allowing the establishment of similarities and differences in a data set. [11][12][13][14][15][16][17][18][19][20][21] In this study, the contents of eleven trace elements (As, Cd, Cr, Cu, Li, Mn, Mo, Ni, Pb, Sb and Se) were determined in muscle, gills, stomach, liver, kidney and gonads of six selected fish species from Todos os Santos Bay, Bahia State, Brazil. The employed analytical technique was the inductively coupled plasma mass spectrometry (ICP-MS) and the investigated fish species were Caranx latus ("guarajuba"), Bagre marinus ("bagre"), Archosargus rhomboidalis ("sambuio"), Lutjanus synagris ("ariacó"), Scomberomorus cavalla ("cavala") and Sphyraena guachancho ("bicuda").…”

Levels of As, Cd, Cr, Cu, Li, Mn, Mo, Ni, Pb, Sb and Se in muscle, gill, stomach, liver, kidney and gonad tissues of six different fish species (Caranx latus, Bagre marinus, Archosargus rhomboidalis, Lutjanus synagris, Scomberomorus cavalla and Sphyraena guachancho) from the Todos os Santos Bay (Bahia State, Brazil) were evaluated. The elements were determined by inductively coupled plasma mass spectrometry (ICP-MS) after wet digestion using reflux system with a cold finger. The detected concentration ranges were as follows (mg kg -1 dry weight): < 0.49-27.31 for As, < 0.013-1.12 for Cd, 0.38-6.05 for Cr, 0.17-28.12 for Cu, < 0.092-1.19 for Li, 0.16-55.9 for Mn, < 0.034-1.24 for Mo, < 0.067-15.57 for Ni, < 0.013-0.60 for Pb, < 0.144 for Sb and 0.57-14.6 for Se. Highest concentrations of trace elements were observed in kidney, liver and gill tissues.

“…The LIBS spectra offer fingerprint data of honey that contains the regional information. Because of the climate, temperature, and environmental factors, honey from different geographical origins might have different elemental constitutes [4]. The elemental difference could be visualized through LIBS spectra.…”

“…[2,3]. However, the constitutes of honey has regional features, and it is likely influenced by the climate, altitude, and other environmental factors [4,5]. Hence, the supplemental information concerning the geographical origin should be given according to Food Safety Law of the People's Republic of China.…”

Traceability of honey is highly required by consumers and food administration with the consideration of food safety and quality. In this study, a technique named laser-induced breakdown spectroscopy (LIBS) was used to fast trace geographical origins of acacia honey and multi-floral honey. LIBS emissions from elements of Mg, Ca, Na, and K had significant differences among different geographical origins. The clusters of honey from different geographical origins were visualized with principal component analysis. In addition, support vector machine (SVM) and linear discrimination analysis (LDA) were used to quantitively classify the origins. The results indicated that SVM performed better than LDA, and the discriminant results of multi-floral honey were better than acacia honey. The accuracy and mean average precision for multi-floral honey were 99.7% and 99.7%, respectively. This study provided a fast approach for geographical origin classification, and might be helpful for food traceability.

“…Frequently, heavy metal concentrations in honey are low, complicating the analysis of these elements. This complication is directly evidenced in the quality of obtained results, where any loss during the analytical processing of samples influences the concentration values determined for each metal [35].…”

Metals are pollutant residues detectable in honey and in fact account for most of the inorganic pollutants found in this food product. Metal pollutants can be accumulated through the food chain and, at levels exceeding safe thresholds, can be toxic to humans and even damage physiological functions. During the honey-making process, bees can transport pollutants to the beehive following contact with polluted botanic species or from drinking contaminated water. Detecting very low concentrations is a persisting challenge to accurately measure these elements in honey. Additionally, since honey is a complex organic matrix, treatments are needed prior to applying any classical chemical methods for metal determination, such as inductively coupled plasma and atomic absorption spectroscopy. Therefore, optimal results are dependent on adequate sample conditioning prior to heavy metal content analyses. Chemical pretreatments include calcination processes and/or acid digestion. Regarding execution, the last steps of any metal detection methodology are the primary determinants of result quality, where any loss of mass is reflected by unreliable values.
