FAAS - Opis:
- This paper presents the result of the determination of the total content of Cu, Pb and Zn by the method of atomic absorption spectrometry with atomization in an air-acetylene flame in Polish honeys samples. The research material was a honeydew, monofloral honey and buckwheat honey. For the mineralization of samples, the following solutions were applied: 1) HNO3(conc), 2) HNO3(conc) and H2O2(conc) in the volume ratio equal to 4:1 and 3:1. On the basis of the results and recommended food standards the percentage of the recommended dietary allowances (RDA) in connection with the consumption of 100 g of product were estimated. To verify the results validation of analytical method used was carried out. It was included defining the following validation parameters values: the limit of detection and quantification; linearity and measurement range; repeatability and accuracy of the results. The contamination of the analyzed honeys by Pb is higher than the acceptable level of contamination of this element. The highest contents of Cu and Zn were characterized by monofloral honeys.
