title: [Evaluation of cadmium, mercury and lead intake with reproduced weekly food rations].
abstract: In Lublin, Olsztyn, Poznań, Warszawa and Wrocław, weekly food rations characteristic of families other than those of manual workers, with medium incomes, were reproduced. Food rations comprised ca. 90 food products whose average weekly intakes were established consistently with the results of questionnaires of the Chief Census Bureau. Namely, from these results we calculated and prepared the average weekly food rations (from 11 470 g to 14 732 g), in which cadmium, mercury and lead were assayed by the ASA method. These average food rations afforded weekly intakes of 105-147 micrograms Cd, 441-931 micrograms Pb and 50.5-119.0 micrograms Hg. According to these results, the average food rations from the above-mentioned cities are moderately contaminated with the heavy metals tested, because in no case 50% of the provisional tolerable weekly intake (PTWI) were exceeded. The present results are lower than those obtained in the same year for families of manual workers; this is probably due to the fact that in the families of manual workers, as compared with other families, the weight of meals is usually higher. It is noteworthy that in the cities with greater numbers of industrial plants the contents of the metals tested, particularly of mercury and lead, in food are higher.
