Abstract:Due to the fact that infants and children are especially sensitive to mercury and arsenic exposure, predominantly through diet, a strict control of the most widely consumed infant foods, especially infant cereals, is of paramount importance. Levels of both total mercury and arsenic in 91 different infant cereals from ten different manufacturers in Spain were determined by flow injection adapted to cold vapor and hydride generation atomic absorption spectrometry, respectively. Cereals were assessed in terms of the different types, the predominating cereal in the formulation, the added ingredients, and whether the cereal was organically or conventionally obtained. In general, the content of toxic elements (median (Q 1 ;Q 3 )) found in infant cereals based on conventionally obtained raw materials (n=74, Hg: 2.11 (0.42;4.58), As: 21.0 (9.4;50.9) µg·Kg ). Mercury content in infant cereals shows the higher values in those formulations with ingredients susceptible to particulate contamination such as gluten-free or cacao-based cereals. The highest arsenic content appears in the rice-based cereals. The mercury and the inorganic arsenic dietary intakes for infants fed on the infant cereals studied were assessed, taking into account the different stages of growth. Organic infant cereals based on cocoa showed the highest risk intakes of mercury, very close to exceeding the intake reference. Just the opposite, 95% of the organically produced infant cereals and 70% of the conventional gluten-free infant cereals showed an inadmissible risk of arsenic intake. Thus, it seems prudent to call for continued efforts in standardizing routine quality control and in reducing arsenic levels in infant cereals; in addition it is essential that relevant legislation be established and regulated by EC regarding these two toxic elements.

“…Potential health risks from Pb exposure, especially inducing neurobehavioral and cognitive effects to children, remain a public health priority (Healey 2009). Dietary exposure assessment to Pb has been a current concern in various countries during the last decade (Ikeda et al 2000;Llobet et al 2003;Wilhelm et al 2003;Leblanc et al 2005;Munoz et al 2005;Nasreddine et al 2006;Whyte et al 2009), where the Total Diet Study (TDS) and the duplicate diet study are the most frequently used methods. In China, Pb pollution is one of the most serious environmental problems because of rapidly expanding industrialisation and widespread use of coal combustion for cooking and room heating.…”

Deterministic and probabilistic estimates of the chronic exposure to lead (Pb) for the inhabitants in Jiangsu Province, China, were performed. Pb contamination data were obtained from the national food contamination monitoring programme during 2001-2006 and 2600 samples from 38 commodities in Jiangsu were included. Food consumption data were from the national diet and nutrition survey conducted in 2002, including 3879 subjects aged 2-80 years and 185 children aged 2-6 years in Jiangsu. Contributions from 38 commodities were included in the calculations. Using the provisional tolerable weekly intakes (PTWI) divided into daily intakes (PTWI(d)) of 3.57 microg kg(-1) bw day(-1) in the risk assessment, exposures calculated by the deterministic approach for children and the general population were 77% and 43% of the PTWI(d), respectively, which were nearly similar to the mean intake calculation in the probabilistic approach. The percentage of people whose exposure level exceeded the PTWI(d) for children, the general population, urban population and rural population were 16%, 0.4%, 0.1%, and 0.5%, respectively. The 50th, 95th and 99th percentiles of Pb exposure for children were 2.6, 4.4 and 5.5 microg kg(-1) bw day(-1), respectively. Rice followed by wheat flour and bean products contributed most to the total Pb intake for both children and the general population. This study indicated that the Pb dietary exposure in Jiangsu Province, especially for children, would be a public health concern.

“…TDSs are conducted according to a standardised method to assess the safety of the food supply (WHO 2005a; WHO/ICPS 2005; EFSA/FAO/WHO 2011). Many countries worldwide have conducted their own TDS to assess dietary exposure to trace elements, like Lebanon (Nasreddine et al 2006(Nasreddine et al , 2010, France (Leblanc et al 2005;ANSES 2011;Arnich et al 2012), Italy (Lombardi-Boccia et al 2003;Turconi et al 2009), Chile (Muñoz et al 2005), Korea (Lee et al 2006), Canada (Health Canada 2003, 2006, Australia-New Zealand (FSANZ 2003(FSANZ , 2008(FSANZ , 2011, New Zealand (NZFSA 2005), the United States (Egan et al 2002), and Cameroon (Gimou et al 2013).…”

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.
