摘要

A total of 28 minerals and trace elements from 1319 food samples typically consumed by the French population were determined during the second French Total Diet Study (TDS). Among the main trace elements analysed by inductively coupled plasma-mass spectrometry (ICP-MS) after microwave-assisted digestion, strontium (Sr), silver (Ag), tin (Sn), barium (Ba), iron (Fe), tellurium (Te), gallium (Ga), germanium (Ge) and vanadium (V) were retained for this work and their occurrence data reported here. The contents were compared using data from worldwide total diet studies. Data for tin in canned food and beverages were compared with European guidelines. The food groups with the highest levels were 鈥淪weeteners, honey and confectionery鈥?with dark chocolate (for Sr, Ag, Sn, Te, Ba, Fe Ga, Ge and V), 鈥淔ish and fish products鈥?and particularly 鈥淪hellfish鈥?(for Sr (14.3 mg kg^鈭?), Ag (5.18 mg kg^鈭?), Ga (0.002 mg kg^鈭?), Ge (0.004 mg kg^鈭?), Te (0.003 mg kg^鈭?) and V (0.234 mg kg^鈭?)), 鈥淭ofu鈥?(for Sr (2.71 mg kg^鈭?), Fe (29.0 mg kg^鈭?) and Ba (0.824 mg kg^鈭?)), 鈥淚ce cream鈥?(Ba (0.621 mg kg^鈭?), Fe (45.5 mg kg^鈭?), Ag (0.193 mg kg^鈭?)) and 鈥淔at and oil鈥?(for Te, Ga and Ge). Moreover, the highest concentrations of Sn were found in 鈥淔ruits and vegetables鈥?(0.522 mg kg^鈭?).
