“…It was not possible to participate in interlaboratory comparison with all elements of the method but nine elements (As, Al, Co, Cu, Mo, Cd, Sn, Hg, and Pb) have been monitored in several matrices. In 1998-2008, for Pb, Cd and Hg, 95.5% of results for Z-score were acceptable for FAPAS (n = 46) and 97.8% for ISS (n = 44) (Noë l et al, 2009). During the period 2007-2009, for six elements (As, Al, Co, Cu, Mo, Table 9 Results of trueness for Ga, Ge, Ag and Te spiked with 5 and 20 mg L À1 on veal, carrot or corn.…”

“…After cooling, sample solutions were quantitatively transferred into 50 ml polyethylene flasks with 100 ll of internal standard solution (1 mg/l) and the digested samples were then completed with ultrapure water to the final volume before analysis by ICP-MS. The ICP-MS methods have already been fully validated (including participation in proficiency tests) for the simultaneous analysis of cadmium, lead, mercury, arsenic (in standard mode), chromium, iron and selenium (in CCT mode) content in foodstuffs of animal origin (Dufailly, Noël, & Guérin, 2006;Noël et al, 2005Noël et al, , 2009. The performance criteria of the method for all other elements have also been estimated and all proficiency tests were satisfactory for fish and seafood samples (Millour et al, 2011;Noël et al, 2009 …”

“…The EQC results indicated that all Zscores obtained in these PTs were acceptable, except one out of three for Cr (Z = 4) in a milk powder sample for a concentration level near the LOQ. This test scheme has already been discussed in detail by Millour et al (2010) and Noël et al (2009).…”

Dietary exposure to trace elements (aluminium, antimony, barium, cadmium, lead, nickel, vanadium, copper, manganese, molybdenum, germanium, lithium, strontium and tellurium) was assessed by the total diet study (TDS) method. Sixty-four pooled samples representing 96.5% of the diet in Yaoundé, Cameroon, were prepared "as consumed" before analysis. Consumption data were sourced from a households' budget survey. Dietary exposures were compared with health-based guidance or nutritional values and to worldwide TDS results. The health-based guidance value was exceeded by ≤ 0.2% of the study population for aluminium, antimony, barium, cadmium, nickel and vanadium. For lead, the observed 95th percentile of exposure (3.05 µg kg(-1) body weight day(-1)) equals the critical value considered by JECFA for cardiovascular effects; therefore, risk to health cannot be excluded for certain consumer groups. The population at risk of excess intake for manganese, copper, molybdenum and nickel was considered to be low (≤ 0.3%). The prevalence of inadequate intake was estimated at 5.9% for copper and was nil for molybdenum. Due to the lack of toxicological and/or nutritional consistent data to perform a risk assessment, dietary exposures to germanium, lithium, strontium and tellurium were provided as supplementary data. The food groups highest contributors to exposure were "tubers and starches" for aluminium (27%), lead (39%) and copper (26%), "cereals and cereal products" for cadmium (54%) and manganese (35%), "fruits, vegetables and oilseeds" for barium (34%), molybdenum (49%) and nickel (31%), "beverages" for antimony (27%) and "fish" for vanadium (43% - lower bound). Measures should be recommended to maintain low levels of exposure before the problem could become an important health or trade issue.
