“…The presence of toxic elements in propolis is associated with environmental pollution of anthropic origin around the apiaries through various sources, such as air, water, plants and soil. Some probable sources for cadmium and lead emissions are industrial sources [ 14 , 15 , 16 , 17 ]. Actually, some plant species are known and well characterized regarding their capacity to accumulate high levels of heavy metals in their biomass.…”

The potential of near infrared spectroscopy (NIR) with remote reflectance fiber-optic probes for determining the mineral composition of propolis was evaluated. This technology allows direct measurements without prior sample treatment. Ninety one samples of propolis were collected in Chile (Bio-Bio region) and Spain (Castilla-León and Galicia regions). The minerals measured were aluminum, calcium, iron, potassium, magnesium, phosphorus, and some potentially toxic trace elements such as zinc, chromium, nickel, copper and lead. The modified partial least squares (MPLS) regression method was used to develop the NIR calibration model. The determination coefficient (R2) and root mean square error of prediction (RMSEP) obtained for aluminum (0.79, 53), calcium (0.83, 94), iron (0.69, 134) potassium (0.95, 117), magnesium (0.70, 99), phosphorus (0.94, 24) zinc (0.87, 10) chromium (0.48, 0.6) nickel (0.52, 0.7) copper (0.64, 0.9) and lead (0.70, 2) in ppm. The results demonstrated that the capacity for prediction can be considered good for wide ranges of potassium, phosphorus and zinc concentrations, and acceptable for aluminum, calcium, magnesium, iron and lead. This indicated that the NIR method is comparable to chemical methods. The method is of interest in the rapid prediction of potentially toxic elements in propolis before consumption.

“…Then, other mineral sources should be provides by the diet in order to satisfy the requirements of adult individuals (18-50 years old). Taking into account that the suggested daily intake (SDI) of commercial pollen is about 13.5 g/day [9], the studied pollen could provides the following percentages of the mineral RDI by FNB and AAC: 3% K; 1.6 -2 % Ca; 1.7 -3 % P; 97.5 -219 % Fe; 3 -3.9 % Mg; 1.5 % Na; 17.4 -22 % Mn; 1.5 -2.9 % Zn and 28.6 -36.4% Se. Pb was not detected.…”

The aim of this work is to evaluate the mineral and heavy metal contents of Acacia caven (Mol.) Molina pollen, a South American plant which grows in the Northwest of Argentina, for studying its behavior as bio-indicator of environmental pollution and their consequences as dietary supplement. Mineral and heavy metal contents were determined by flame atomic absorption / emission spectrometry (FAAS and FAES, respectively), inductively coupled plasma optical emission spectrometry (ICP-OES) and hydride generation atomic absorption spectrometry (HG-AAS). The obtained results demonstrated that some mineral contents (K, Ca, P, Fe, Mg, Na, Zn and Se) of Acacia caven pollen met the requirements of both, the Food and Nutritional Board (FNB) and the Argentinean Alimentarius Codex (AAC) to be used as a dietary supplement. Nevertheless, some heavy metals analyzed such as Al, Cu, Ni, V, Cr and Cd, exceeded the upper levels (UL) established by FNB and AAC, probably due to environmental contamination. Beyond the high level of some heavy metals found in the Acacia caven pollen, this could be an important dietary supplement by their high Fe and low Na contents. Considering that the suggested doses of commercial pollen by pharmacists and companies advice is 13.5 g/day, an only doses of Acacia caven pollen would satisfy the recommended daily intake (RDI) of Fe given by FNB for an adult individual. In spite of this promising date, further studies on the Fe bioavailability and heavy metal toxicity from Acacia caven pollen should be carried out for being used this pollen as dietary supplement.

“…The majority of studies on the dietary intake of metals are country specific and show no predominance for any particular element. [250][251][252][253] The Mo content in food consumed in Japan was assessed by ICP-MS. 254 The overall Mo intake of the Japanese population is estimated as 225 mg d À1 with the principal dietary source being rice followed by soy bean products. The authors showed that while the Mo content of most animal foods was less than 0.1 mg g À1 , that of cereals was greater than 0.5 mg g À1 .…”
