Przedstawiono rozkład przestrzenny i stopień zmienności zawartości Fe i Mn w igłach i korze sosny zwyczajnej (Pinus sylvestris L.) oraz plechach epifitycznego porostu Hypogymnia physodes (L.) Nyl. na obszarze trzech polskich parków narodowych o zróżnicowanym wpływie zanieczyszczeń: Magurskiego, Świętokrzyskiego i Wigierskiego.

In 2002, 78 samples of Scots pine (.Pinus sylvestris L.) needles, 22 samples of pine bark and 22 samples of epiphytic lichen Hypogymnia physodes (L.) Nyl. were collected in three Polish National Parks, i.e. Magurski, Świętokrzyski and Wigierski. Fe and Mn were determined using an ICP-AES method. The samples were digested with diluted HN03 (1:1). The concentrations of Fe and Mn in Scots pine needles have increased with their age. The highest mean concentrations of Fe were found in the pine needles of Magurski National Park, the lower ones in Świętokrzyski National Park, and the lowest in Wigierski National Park. The pine needles of Świętokrzyski National Park accumulated almost twice as much Mn compared to those of the remaining parks. The pine bark reveals the lowest concentration of Mn. The highest content of this element is recorded in the pine bark of Świętokrzyski, whereas the lowest in that of Magurski National Park. Compared to their host pine bark, the lichen thalii display distinctly raised levels of Fe and Mn.
