    Trace elements, natural antioxidants and contaminants. Technical workshop. Helsinki-Espoo (ISL), 1995/08/25.

    The purpose of this study was to monitor the intake of potentially toxic contaminants, heavy metals and nutrients.

    Lead, cadmium, mercury, nickel, molybdenum, copper, iron, zinc and manganese were studied.

    Intakes of four populations were estimated from their daily diets and compared with the Acceptable Daily Intakes (ADI) or the Provisional Tolerable Weekly Intakes (PTWE) as established by the FAO/WHO to estimate the risk of toxicity and recommended Spanish Intake (RI) or the US Recommended Daily Allowances (RDA) or the US Safe and Adequate Daily Dietary Intakes (ESADDI).

    Representative market basket diets (foods providing the 95% of the total energy intake) from four Spanish regions, Andalucia, Galicia, Madrid and Valencia, were collected and determined for trace element contents.

    Data on the contribution of food groups to the total daily intake of trace elements were also obtained.

    Daily lead intakes from the diets ranged from 37 and 521 mug/day, with the Madrid population having the highest average Pb intake and exceeding the PTWI.

    Average total dietary cadmium intakes were about 25-45% of the PTWI.

    The intake of mercury, which is mainly derived from the fish group (66-90%), was about 9-17% of the PTWI.

    Daily intakes of iron and zinc in the four areas were below the ADI.

    In Madrid the intake of copper was within the range of the maximum acceptable daily intake of this element.

    A database listing the contents of heavy metals in 234 food items was created. (...)
