Evaluation of plant products from the Legnicko–Głogowski region for their contamination with arsenic

Traceability along the production chain of Italian tomato products on the basis of stable isotopes and mineral composition

“…The concentrations of RREs are in agreement with the values reported by Spalla et al, [47] confirming also that the content of light REEs (La, Ce, Pr, Nd and Sm) is significantly higher than that of the heavy REEs (Gd, Dy, Ho, Tm and Yb). The contents of K, P, Ca, Mg, Zn, Mn, Rb, Sr, Co, Se and Al are in the ranges previously reported, [8][9][10][11][14][15][16][17]48] except for those reported by Nakano and Uehara, [21] who measured values of P, K, Ca and Mg higher than ours in tomatoes grown with different fertilizers. The Na content in tomatoes agrees with that found by Thybo et al, [15] Kelly and Bateman, [13] LoIudice et al [11] and Guil-Guerrero with Rebolloso-Fuentes, [20] but it is higher than that measured by Incrocci et al [48] in tomatoes grown in soilless cultures and lower than those reported by Demirbas for Turkish tomatoes, [16] Hernandez-Suarez et al for tomatoes from Tenerife [12] and Gundersen et al for tomatoes grown in greenhouses.…”

“…[14] The Cu, Ni, Pb and Cd values are lower than those reported by Ekholm et al for tomatoes grown in Finland [9] and higher than those measured by Gundersen et al, [14] but are in agreement with the data reported by other authors. [16] The As and Cr values are far below those measured by Bronkowska et al in tomatoes grown in a region with copper works [10] and by Bratakos et al in Greek tomatoes. [8] The chloride and phosphate contents in tomatoes are similar to those previously reported, whereas the sulphate content is lower than that quoted in two previous studies.…”

“…Pb, Cd, As, Al) but also biologically essential (e.g. Ca, Mg, K, P, Cr) elements were determined in order to verify the mean intake through the human diet 8–10. Few authors have considered using the elemental composition of tomato products to differentiate them on the basis of their geographical origin or cultivars 11–13.…”
