title: [Estimation of selected bioelements content in vegetables].
abstract: Concentrations of Ca, P, Fe, Zn and Cu were determined in 30 different kinds of fresh vegetables available in sale. The contents of chemical elements (except phosphorus) were analysed, after dry mineralization, by flame atomic absorption spectrometry--AAS with deuterium background correction. The phosphorus was determined in the form of phosphormolybdate blue by spectrophotometric method. Reliability of the procedure was checked by the analysis of certified reference materials. The average contents (mg/100 g) of minerals in vegetables were as follows: 2.57 - 165 for Ca; 22.1 - 95.4 for P; 0.07 - 0.82 for Zn; 0.01 - 0.16 for Cu and 0.27 - 3.31 for Fe. These measurements allowed to estimate the realisation of the recommended daily intake of bioelements with the analysed vegetables for an adult person.
