“…Intakes of lead in this study were lower than for other Canadian dietary intake studies (table 6), which reported 138//g/day (Kirkpatrick and Coffin 1974) and 106/zg/day (Meranger and Smith 1972) excluding drinking water; however, there are several possible reasons for this. Firstly, at the time the previous studies were done, there were insufficiently sensitive methods available and the detection limit of the analytical method used in those studies was about 20-70 ng/g, or a factor of 100-500 greater than that used in this study.…”

“…The latter value for males agrees well with our value of 3039 g/day for males. Our value of 2569 g/day is higher than estimates of 1784 g/day for Canada which does not include drinking water (Meranger and Smith 1972;Kirkpatrick and Coffin 1974), 1733 g/day for Sweden (Slorach et al 1983), and 1460 g/day for the UK (Steering Group on Food Surveillance 1982); however, it is significantly lower than an estimate of 3543 g/day for Holland (de Vos et al 1984). Thus, our mean food intake appears reasonable and does not border on the extremities of published food intake data.…”

Twenty-four hour duplicate diets, including drinking water and snacks, were collected from 24 adults living in five Canadian cities. Each diet was separated by the participants into 10 food categories, and each of the samples was analyzed in duplicate for lead, cadmium, arsenic and fluoride. Minimum detection limits for the respective elements in foods were about 0.1, 0.01, 0.3 and 5 ng/g. Mean dietary intakes were 53.8 micrograms/day or 0.80 micrograms/kg/day for lead, 13.8 micrograms/day or 0.21 micrograms/kg/day for cadmium, and 16.7 micrograms/day or 0.26 micrograms/kg/day for arsenic. The median intakes were 42.7 micrograms/day or 0.57 mu/kg/day for lead, 11.9 micrograms/day or 0.17 micrograms/kg/day for cadmium, and 9.79 micrograms/day or 0.139 micrograms/kg/day for arsenic. Half of the participants lived in communities with 1 microgram/g fluoride in the drinking water, and half lived in cities with less than 0.2 microgram/g fluoride in the water. The dietary intake of fluoride for the former was 2802 micrograms/day or 39.7 micrograms/kg/day; while that of the latter was 563 micrograms/day or 8.5 micrograms/kg/day. The respective median intakes of fluoride were 2090 micrograms/day or 30.3 micrograms/kg/day, and 414 micrograms/day or 7.0 micrograms/kg/day. Contribution of individual foods and food categories to the dietary intakes is discussed.

“…Chromium intakes from Canadian diets have been reported to be between 136 and 282/zg/day (Kirkpatrick andCoffin 1974, Meranger andSmith 1972). Dick et al (1978) reported values of 229 /ug/day for the mean dietary intake of chromium in New Zealand diets.…”

“…Among possible sources for such ingestion it is known that varying amounts of nickel occur in our food (Dencker et al 1971, Kirkpatrick & Coffin 1974. This contamination may originate from the native foodstuffs (Schroeder et al 1962) but a certain amount may also be added when cooking and storing (Thomas et al 1974).…”
