Determination of Selenium in Human Milk
Department of Environmental Medicine, Faculty of Medicine, Komenský University, Bratislava, Slovak Republic
A method of Se determination in human milk by AAS using electrothermal atomization and a Zeeman background correction is described. The matrix modifier (Pd(NO3)2) concentration, sample dilution, ashing and atomization temperatures were optimised. For calculation of the results, the calibration curve method was used. Se concentrations in human milk were measured in eight Slovak localities. The mean Se level (14.27 μg kg-1) was considerably lower compared with neighbouring countries.
