Mieszkańcy strefy ochronnej Huty im. T. Sendzimira pobierali żelazo, cynk, miedź oraz nikiel w ilościach odpowiednio 12,54, 12,55 i 1,00 mg oraz 132 µg, przy współczynnikach zmienności 59% dla niklu i -32% dla pozostałych metali. Wymienione wartości pobrania metali pozwoliły na pokrycie zalecanego spożycia odpowiednio w 96, 110 i 43% oraz pokrycie przypuszczalnego zapotrzebowania na nikiel w 130%.

The object of the study was to assess the intake of iron, zinc, copper and nickel in the inhabitants of selected farms situated within the area affected by steel works emission. Of the 62 people taking part in the study, girls and boys aged 10-18 accounted for 14% and 10%, respectively (24%), while men and women aged 19-84 constituted 46% and 30%, respectively (76%) of the participants. A seven-day food record and personal questionnaire including information on age, sex, job, physiological condition were kept and filled in for each of the farm inhabitants. Weighted average mass of the food rations and weighted average recommended intake values were calculated from those data. Food rations (280 units) were collected during two successive years from autumn 1996 to spring 1998. The individual rations were weighed and the amount of waste was determined. The rations were then homogenized, frozen and lyophilized. The lyophilized food rations were dry-mineralized, and the ash was dissolved in HNO3 solution (1/2 HNO3/H2O volume ratio). Iron, copper and zinc contents in the resultant solution were determined on a Philips PU 9100 Absorption Spectrophotometer. An ICP-AES Jobin Ivon JY-238 Ultrac Emission Spectrometer was used to determine the amount of nickel in the solution as recommended by the manufacturer. Iron, zinc, copper and nickel intakes of the inhabitants of the buffer zone were 12.54 mg, 12.55 mg, 1.00 mg, 132 µg, respectively, and the values of the coefficient of variation were 59% for nickel and ca. 32% for the remaining metals. Those values correspond to 96%, 110% and 53% of the recommended intake of iron, zinc and copper, respectively, and to 130% of the probable recommended intake of nickel.
