“…Likewise Guerra et al [35] in São Paulo in Brazil found a total Cd content of 0.02 to 0.04 ppm. Another study reported by Radwan and Salama [36] in Egypt shown a value of 0.01 ppm for total Pb. By contrast, the results found are lower than those found by Parveen et al [37] in Pakistan with values of 1.33 ppm for total Cd and 1.56 ppm for total Pb; Kananke et al [38] with values from 0.18 to 1.59 for total Pb and Al-Chaarani et al [39] in Tripoli (Lebanon) with values of 0.17 to 0.82 ppm for total Cd.…”

Tomato (Lycopersicon esculentum Mill) is quantitatively the highest vegetable consumed in Burkina Faso. The objective of this study was to evaluate the physico-chemical, nutritional characteristics, and sanitary quality of the tomato variety Mongal F1 from different production sites. Twenty-eight (28) samples of Mongal F1 fresh tomatoes were collected from 28 producers at three different localities of Ouahigouya, Loumbila and Ouagadougou. The physico-chemical and nutritional characteristics were determined by standardized methods and the traces metallic elements by atomic absorption spectrophotometry. The results revealed a degree brix varying from 4.07˚ to 5.50˚ and a pH ranging from 3.71 to 4.08 corresponding to a total acidity of 0.39% to 0.55% citric acid equivalents. The moisture content, the ash content, the total carbohydrates content, the reducing carbohydrates content, the lipids content and the protein content were ranged from 95.09% to 96.17%, 9.25% to 10.60%, 47.00% to 53.43%, 30.03% to 41.21%, 3.04% to 7.71% and 17.09% to 25.03% respectively. The results of the trace metals showed a high accumulation of total cadmium from 0.11 to 0.22 ppm, of total lead of 1.15 to 1.27 ppm and arsenic total of 0.19 to 0.20 ppm. The results proved that environmental conditions influence the quality of the tomato Mongal F1. Detection of trace elements in the tomato fruits suggests that a better production practices are needed.

“…The value of HRI more than 1 indicates considerable risk of negative impact on human health. National and International regulations on food quality have lowered the maximum permissible levels of toxic metals in human food; hence, an increasingly important aspect of food quality should be to control the concentrations of trace metals in food (Radwan et al, 2006). The residues of the heavy metals still appear as pollutants in vegetables as well as in the environment.…”

Inductively Coupled Plasma -Optical Emission Spectrometry (ICP-OES) was used to estimate and evaluate the levels of heavy metals in vegetables collected from various sites of Ranchi city (tribal dominated population) followed by health risk assessment by determining Metal Pollution Index (MPI), Daily intake of metal (DIM) and Health Risk Index (HRI). The concentration levels of Pb, Cd and Ni in vegetables were found to contain beyond than the permissible PFA limit. All sites showed quite a few higher concentrations of Lead (Pb), than the permissible PFA limit.

“…Considering the high number of celiac, these information are urgently required so that the daily dietary element intakes in the celiac population can be estimated from available food consumption data. While element intake levels for non-celiac people are documented [12][13][14][15] there is as yet no information available for celiac ones. Also, this study wants to investigate if any toxic elements could be found in the gluten-free foods and the daily intake from diets composed according to reference intake levels.…”

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.
