This paper is the first analytical approach to the study of twenty heavy metals in the gluten-free foods for celiac people. Only the ICP-MS technique was used. One of the advantages about the use of ICP-MS for this characterization is the high sensitivity that improved the limits of quantification levels for some elements that are present at low quantities in some samples.The concentration values of As, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn, V and Zn in seventeen glutenfree food samples are reported. The highest arsenic and molybdenum levels were measured in Rice noodle from China (0.088 and 0.47 mg kg −1 , respectively). The highest concentrations of some metals (Cu, Ba, Cd, Pb, Hg, Sr and V) were found in bread and breadstick samples produced in different bakeries located at Palermo. To examine the overall heavy metal concentrations in all gluten-free samples analyzed, metal pollution index (MPI) was calculated. Gluten-free foods analyzed contain levels of trace elements under the limits tolerated by the law. Considering the average concentrations of some trace elements found in the present study, it can be concluded that they are inadequate if compared with the recommended daily intake by international organisms, providing from 1.1 to 53% of the RDI for the essential metals. These conclusions are in good agreement to some authors affirming that commercial gluten-free cereal foods, made of refined flours or starches, are of lower nutritional value compared to their wheat counterparts. The metal pollution index and health risk index of heavy metals also suggest that Cd, Pb and Ni contamination in most of the test gluten-free food had potential for human health risk due to consumption of food at contaminated not industrial laboratory. Considering our data, health risk index was lower than 1 for all the samples except nickel in a sample of pasta.

Plants are essential sources of bioactive substances that promote health. For economic reasons, farmers usually focus on obtaining higher yields rather than crop nutraceutical quality. The application of non-essential elements (NEEs) is a technique used to increase secondary metabolites (SMs) in plants. This technique includes variations of the essential elements ratios in a nutrient solution or the inclusion of elicitors, such as salicylic acid or methyl jasmonate. Elicitor use is controversial because plants grow differently in inert substrates, in vitro and soil. Soil contains essential elements (EEs) and NEEs that can enhance SM synthesis and increase nutraceutical plant quality. However, any technique that modifies plant metabolism can decrease yields. Thus, developing techniques to increase both agricultural product yield and quality is necessary. This review aims to demonstrate the necessity for a new recipe or "cocktail" of plant nutrients based on EEs and NEEs, and elicitors apply to achieve both a high yield and crops nutraceutical quality.

“…These values were considerably higher than the 100 μg/kg found in grain of white rice in Spain (Matos-Reyes et al 2010) or 140-170 μg/kg in Japan (Sun et al 2014). The usual total As concentration in the grain obtained from uncontaminated soils ranges from 80 and 200 μg/kg (Zavala and Duxbury 2008), while the upper level was allowed by WHO (2010) as non-toxic level.…”

“…Higher values (67 μg/kg) were found by Matos-Reyes et al (2010) in south-east Spain, or by Ventura et al (2007) in Portugal (40 μg/kg) in white rice grain. Therefore, a consumption of 150 g of white rice might provide an intake ranging from 5.6 to 12.6 μg Se per day, with a mean value of 10 μg Se per day.…”

“…Within Spain, the Vegas Altas region of Extremadura has the oldest and most important rice fields of Spain, with about 20 000 ha, with a grain production of about 140 000 t (MARM 2014). Total Se and As concentrations in rice grains range between 40 μg Se/kg (Ventura et al 2007) and 67 μg Se/kg (Matos-Reyes et al 2010) in Portugal and south-east of Spain, while the As concentrations found are about 105 μg As/kg (Matos-Reyes et al 2010). …”

Rodrigo S., Santamaria O., Perez-Izquierdo L., Poblaciones M.J. (2017): Arsenic and selenium levels in rice fields from south-west of Spain: influence of the years of monoculture. Plant Soil Environ., 63: 184-188.There is a lack of information regarding the arsenic (As) and selenium (Se) concentrations in Spanish rice (Oryza sativa L.) fields and how soil conditions affect such concentration, especially those derived from the typical monoculture practiced in the studied area. To clarify these aspects, 76 soil samples and 95 grain samples were collected from 19 rice fields along the Vegas Altas area, the most important rice growing area of south-west of Spain. The results suggested a significant increase in the soil total As and Se concentrations as the number of monoculture years increased. While As concentration reached toxic levels in 12 out of the 19 locations, Se concentration in all the analysed fields could be considered as deficient. An increase of the As and Se concentration in soil produced a subsequent increase of the concentration of both elements in the rice grain. Therefore, it might be extremely important to control both levels. It would be necessary to establish different actions, including rotations with other crops, in order to remediate As accumulation and to increase Se intake.
