Radioactive isotopes, both natural and artificial, present in the environment, may be convenient indicators that can be used to study many physical and chemical processes as well as the transport of pollutants in the ecosystem. The studies have shown that in identification of particulate matter emission sources a radioactive lead isotope (Pb-210) can be used. The Pb-210 increased activity concentration in the top soil layers suggests its current atmospheric deposition. This conclusion is confirmed by the results of the Principal Components Analysis, conducted using the measured radionuclide content in 0-30 cm deep soil layer samples.

Passive biomonitoring using 210Pb was used in the paper to evaluate pollutant deposition. Well-developed epiphytic foliose lichens Hypogymnia physodes growing on spruce branches were used in the studies. The samples of mosses Pleurozium schreberi and soil (raw humus) were collected from the area around the tree from which the samples of lichens were collected. The studies have shown that it is possible to identify dust emission sources using a radioactive lead isotope (210Pb). The highest activity of 210Pb was observed in areas with increased deposition of other pollutants, such as Ni, Cd, Cu and Pb, which may indicate that 210Pb is one of the emission components

W pracy zastosowano biomonitoring pasywny, z wykorzystaniem 210Pb, do oceny depozycji zanieczyszczeń. Do badań wykorzystano dobrze wykształcone epifityczne porosty listkowate Hypogymnia physodes, porastające gałęzie świerka. Wokół drzewa, z którego pobrano próbki porostów, pobierano próbki mchów Pleurozium schreberi oraz gleby - próchnicy nadkładowej. W prowadzonych badaniach stwierdzono, że możliwa jest identyfikacja źródeł emisji pyłu przy wykorzystaniu radioaktywnego izotopu ołowiu - 210Pb. Największe aktywności 210Pb zaobserwowano na terenach o zwiększonej depozycji innych zanieczyszczeń, np. Ni, Cd, Cu i Pb, co może wskazywać, że 210Pb jest jednym z komponentów emisji
