摘　　要：The research presents the first results of aluminium speciation analysis in aqueous extracts of individual plant parts of Betula pendula and soil samples, using High Performance Ion Chromatography with Diode Array Detection（HPIC-DAD）. The applied method allowed us to carry out a full speciation analysis of aluminium in the form of predominant aluminium–fluoride complexes： AlF（（x = 2,3,4））^（（3-x））（first analytical signal）, AlF^（2＋）（second analytical signal） and Al^（3＋）（third analytical signal） in samples of lateral roots, tap roots, twigs, stem, leaf and soil collected under roots of B. pendula. Concentrations of aluminium and its complexes were determined for two types of environment characterised by different degree of human impact：contaminated site of the Chemical Plant in Luboń and protected area of the Wielkopolski National Park. For all the analysed samples of B. pendula and soil, AlF（（x = 2,3,4））^（（3-x））had the largest contribution, followed by Al^（3＋）and AlF^（2＋）. Significant differences in concentration and contribution of Al–F complexes and Al^（3＋）form, depending on the place of sampling（different anthropogenic pressure） and plant part of B. pendula were observed. Based on the obtained results, it was found that transport of aluminium is ＂blocked＂ by lateral roots, and is closely related to Al content of soil.The research presents the first results of aluminium speciation analysis in aqueous extracts of individual plant parts of Betula pendula and soil samples, using High Performance Ion Chromatography with Diode Array Detection（HPIC-DAD）.
