“…With this purpose different analytical methods such as atomic spectrometry, electroanalytical techniques, mass spectrometry or nuclear activation analysis could be used (WHO/FAO/IAEA 1996). But electrothermal atomic absorption spectroscopy has been selected because of its high sensitivity and low detection limit, established as one of the most common methods to determine cadmium and lead in food after dry or wet ashing of organic matter (Nazari, 2008;Ajtony, Bencs, Haraszi, Szigeti, & Szoboszlai, 2007;Correia, Oliveira, & Oliveira, 2000).…”

Abstract:Lead and cadmium have become highly toxic metallic elements. There is an obvious toxicological impact of these elements on infants since their intestinal absorption is significantly higher than in adults, thus it is desirable to quantify lead and cadmium levels in commonly consumed infant foods. Zeeman background correction, transversely heated graphite furnace atomic absorption spectrometry, was used to determine both the lead and cadmium content of 91 Spanish infant cereals. Cereals were assessed in terms of different types, cereal predominant in formulation and whether it was obtained organically or conventionally. Preliminary analysis revealed a noticeably higher content of lead and cadmium (median, Q1-Q3) in organic cereals (n = 17, Pb: 26.07; Cd: 18.52;.50 µg kg -1 ) in relation to conventional ones (n =74, Pb: 10.78; Cd: 7.12;.77 µg kg -1 ). Three formulations exceeded European lead maximum levels. Added ingredients (milk, cocoa, fruit and honey) to the cereal base provide lead enrichment. For cadmium, this pattern was observed by cereal based on cocoa, but also the raw materials contributed with a dilution phenomenon, decreasing the final cadmium concentration in infant cereal. Apart from several organically produced cereals, lead content showed a narrow variation, where gluten-free cereals provide lower cadmium content than formulations containing gluten. Dietary intakes of both elements were assessed in comparison with the reference intake values proposed by the EFSA Panel on Contaminants in the Food Chain. Organic infant cereals based on honey and cocoa supplied the highest risk intakes of lead and cadmium, respectively. In accordance with the actual state of knowledge on lead and cadmium toxicity and attending to the upper limits calculated from risk intake values set by EFSA, it seems prudent to call for a revision of both heavy metals content regulated by EC to set a maximum guideline values for infant cereal at 55 and 45 µg kg -1 , respectively.

“…Krunić et al (1989) analyzed honey samples from an area close to a Cu refinery and found t-As concentrations that ranged from 28 to 67 µg kg -1 , similar to the concentrations found in honey samples from San Pedro de Atacama. In contrast, Ajtony et al (2007) analyzed honey from different regions in Hungary and found t-As concentrations from 0.0 to 7.2 µg kg -1 , similar to the t-As concentrations in the honey samples from Chiloé. A recent study on honey from Siena County (Italy), which is an area considered to be relatively free of industrial pollution because its main activity is agriculture, revealed that its t-As concentrations varied from 2.7 to 20.2 µg kg -1 (Pisani et al, 2008).…”

The content of heavy metals in honey is indicative of natural or anthropogenic pollution and has therefore been proposed as a feasible bioindicator for arsenic contamination in different regions of Chile. Total arsenic (t-As) and inorganic As (i-As) concentrations were determined in 227 samples of honey harvested during the years 2007, 2008, and 2009 in the areas of San Pedro de Atacama, Atacama, Chiloé, and Futaleufú, with the last town located 156 km from the Chaitén Volcano (latest eruption in 2008). These analyses were conducted using an atomic absorption spectrophotometer coupled with a hydride generator. In the honey samples, the concentrations of t-As ranged from 2.2 to 171.9 µg kg -1 , and the i-As concentrations ranged from none detected (ND) to 24.6 µg kg -1 , with the area of San Pedro de Atacama having the highest As concentrations. The samples of honey from Futaleufú showed higher As concentrations after the eruption of the Chaitén Volcano in 2008. This study demonstrates that As pollution in honey may originate from both natural and anthropogenic sources. The results indicate that it is appropriate to use honey as a bioindicator of environmental pollution. In addition, the consumption of the honey studied herein does not pose any health hazards to the consumer due to its As content.

“…Among commercially available CRM, one hardly finds an equivalent of the complex honey matrix, in particular with regard to high carbohydrate content. Hence, in many research areas, other CRM like apple leaves (SRM 1515) [3,[8][9][10][11][12], brown bread (BCR 191) [7], or corn (NBS 8413) [4,5] are commonly applied. Due to the lack of matching CRM, other procedures are used, for instance various preparations of samples [3,8] or applying different experimental techniques [13,14].…”

A method for simultaneous ICP-MS determination of 13 elements in three types of honey from Poland is described. The method was validated, and the uncertainty budget was set up. The results obtained for the relative expanded uncertainties U rel (k = 2) were 15.1% for Al, 18.6% for B, 18.8% for Ba, 7.9% for Ca, 24.4% for Cd, 7.24% for Cu, 7.9% for K, 4.8% for Mg, 8.3% for Mn, 12.7% for Na, 14.9% for Ni, 12.5% for Pb and 13.4% for Zn. Traceability of the measurement results was established based on the use of the corn flour CRM INCT-CF-3 and the apple leaves CRM SRM 1515 and by analyzing spiked samples. Recovery rates between 94% (Zn) and 107% (Na) were found. The detection limits of all elements studied showed the suitability of the procedure for routine analyses. Summarizing it can be concluded that the described analytical procedures to measure the mass fractions of 13 elements in honey samples with established traceability and evaluated uncertainty allow to obtain reliable and internationally comparable results.
