  1. Survey of lead, cadmium, fluoride, nickel, and cobalt in food composites and estimation of dietary intakes of these elements by Canadians in 1986-1988.

    Article - En anglais

    During the period 1986-1988, foods were purchased at the retail level in 5 Canadian cities and, for each city, prepared for consumption and combined into 113 composites and 39 composite subsets.

    Lead and cadmium were determined in all the samples ; fluoride, in samples from Winnipeg ; and cobalt and nickel, in samples from Montreal.

    Means and ranges of concentrations (ng/g) found in individual samples were lead, 23.2 (<0.4-523) ; cadmium, 9.96 (<0.02-167) ; fluoride, 325 (11-4970) ; nickel, 196 (<0.6-2521) ; and cobalt, 9.4 (<0.3-75.7).

    Estimated dietary intakes (mug/day) of the elements over all ages and sexes were lead, 24 ; cadmium, 13 ; fluoride, 1763 ; nickel, 286 ; and cobalt, 11.

    During the period 1985-1988, the average level of lead in canned foods decreased from 73.6 to 46 ng/g.
