Abstract
Abstract
In a trial for a comprehensive total diet study, 105 food composites were prepared in the summer of 1985, and another 105 composites in the late fall of 1985. Lead and cadmium were determined In all composites. The mean, median, and range of lead concentrations in the samples were 29.9, 14.7, and 1.42-407 ng/g, respectively. The estimated dietary Ingestion of lead by the average adult Canadian was 36.4 μg/day. The mean, median, and range of cadmium concentrations were 13.7, 5.4, and <0.07- 297 ng/g. Dietary ingestion of cadmium by adults averaged 14.5 μg/day. Sample planning and contamination control for trace element determinations of the study are discussed.
