PL Ze względu na rosnące zanieczyszczenie gleb metalami ciężkimi cenne są wszelkie czynniki powodujące zahamowanie translokacji tych pierwiastków. Wykazano, że naturalnym czynnikiem mogącym ograniczyć przemieszczanie się ksenobiotyków mogą być grzyby mikoryzowe. Badając korzenie z terenów zanieczyszczo[...]
EN Increasing contamination of soils by heavy metals causes increasing interest in factors that inhibit their translocation. It is known that mycorrhizal fungi may be a natural factor which inhibit trnslocation of xenobiotics. It has been shown that mycorrhizal roots accumulate strongly cadmium and lea[...]

PL Gleby na terenie gminy Dąbrowa Górnicza charakteryzują się podwyższoną zawartością metali ciężkich. Najwyższe zawartości ołowiu przekraczają 650 mg/kg, kadmu 15 mg/kg i cynku 1000 mg/kg gleby. Próbki gleby z wybranych punktów podano analizie specjacyjnej według Tessiera w modyfikacji Kerstena i Fors[...]
EN Elevated content of heavy metals in soils is characteristic of the Dąbrowa Górnicza region. The highest concentrations of lead, cadmium and zinc exceed here 650, 15, and 1000 mg/kg of soil, respectively. Samples of soil from selected sites underwent the speciation analysis with the use of the Tessie[...]
