“…The representative nature of the Canadian TDS collection (Health Canada, 2009), which is designed to represent the majority of the foods commonly purchased in Canada, suggested to us that these samples should also be useful for monitoring Na and K in the Canadian food supply. TDS have been conducted in Canada since 1969, although the pattern of sampling and compositing of the food samples purchased has undergone some changes over the decades (Conacher et al, 1989). TDS samples from 1974TDS samples from -1975 from Halifax, Montreal, Winnipeg and Vancouver, had been composited into 10 food groups and assayed for Na and K, showing 2-5-fold higher than recommended intakes for Na (depending on age/sex group (Shah et al, 1982)).…”

“…Toronto was sampled in both the summer of 1992 and the winter of 1996. The foods were prepared for consumption (Conacher et al 1989) by the Department of Food Science, Kemptville College, Ontario Ministry of Agriculture and Food, and combined to constitute 138 composites which represent more than 99% of the Canadian diet. Fifty composites of fatty foods representing approximately 33% of the diet were selected for PCB determinations.…”

Market basket samples representative of food from six Canadian cities were surveyed from 1992 to 1996. Fifty composites of fatty foods, prepared for consumption were analysed for 40 PCB congeners by gas chromatography-mass spectrometry. Fish and butter contained the highest total PCB concentrations, while milk and infant foods contained the lowest. The dairy and meat composites were major contributors to the total PCB intake of 5.7 ng/kg/day, and to the TEQ (2,3,7,8-tetrachloro-p-dibenzodioxin equivalent) intake of 0.11 pg/kg/day. The pattern of congeners was similar for the different food groups with the exception of fish, which contained less tri- and tetra-chlorinated biphenyls and more of the hexachlorinated congener No. 153.

“…To mimimize human exposure, regulations on fish contamination in Canada have been set at 2mg/kg for polychlorinated biphenyls (PCBs) and 20 ng/kg for (2,3,7,. Of all foods for the general Canadian population, fish contains the highest levels of PCBs (1), and one of the highest for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (2).…”

Two remote maritime populations were evaluated for their biological exposure to orgnochlorines in [1989][1990] Because of their high intake ofseafood, these two populations have high biological levels. One hundred nine breast milk samples from Inuit women from Arctic Quebec were analyzed to determine levels of polychlorodibenzo-p-dioxins (PCDDs), polychlorinated dibenzofrans (PCDFs), and coplanar polychlorinated bipheuWls (PCBs) including non-ortho, mono-oriho, and di-outho congeners. Total 2,3,7,-tetrachlorodibenzo-p-dioxin equivalents (TEqs) for PCBs were 3.5 times higher in Inuit milk samples than in 96 Caucasian milk samples. Amongthe 185 fishermen from the Lower North Shore ofthe Gulf of the St. Lawrence River, we evaluated 10 highly exposed fishermen for theircoplanar PCB blood levels. Total TEqs were 900 ng/kg for highly exposed individuals with 36 ng/kg for controls. In these two nonoccupationally exposed populations, coplanar PCBs make a larger contribution to the TEq than PCDDs and PCDFs. However, the mono-ortho penta CB No. 118 is the major contributor for the total toxicity.
