The neutron activation analysis procedure was used to determine the concentration of 42 elements: Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Ni, Co, Zn, As, Se, Br, Rb, Sr, Zr, Nb, Mo, I, Ag, Cd, Sb, Ba, Cs, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Au, Hg, Th, and U accumulated in mosses sampled for testing in September and October 2011 in the Opole Province (Southern Poland). Samples of different moss species were collected near the intersections of the grid lines marked on the map of the province. The distance between the points was approximately 20 km. The analysis of the results made it possible to identify the places of increased deposition of element-pollutants and to indicate the potential sources of emission. Factor analysis revealed four components, two of which are of definite anthropogenic origin. The possible sources of elements are local industry and farming, and distant heavy industry complexes. The results have demonstrated the increased content of Cr, Cd, Hg, and U in moss samples collected in agricultural areas located in the southern part of the province. It has been concluded that the industrial areas of Rybnik and Ostrava and Karvina Coal Basin may be the potential source of emission of these elements.

Metodą neutronowej analizy aktywacyjnej oznaczono stężenia 42 pierwiastków: Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Ni, Co, Zn, As, Se, Br, Rb, Sr, Zr, Nb, Mo, I, Ag, Cd, Sb, Ba, Cs, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Au, Hg, Th i U, zakumulowanych w mchach pobranych do badań we wrześniu i w październiku 2011 roku na terenie województwa opolskiego (południowa Polska). Próbki różnych gatunków mchów pobierano w bliskiej odległości od miejsc przecięcia linii siatki kartograficznej naniesionych na mapę województwa. Odległości pomiędzy punktami wynosiły ok. 20 km. Analiza wyników badań umożliwiła wskazanie miejsc zwiększonej depozycji zanieczyszczeń wraz ze wskazaniem potencjalnych źródeł ich emisji. Wykazano m.in. zwiększoną zawartość Cr, Cd, Hg i U zakumulowanych w próbkach mchów pobranych do badań na obszarach rolniczych położonych na południu województwa. Stwierdzono, że potencjalnym źródłem emisji mogą być uprzemysłowione tereny Rybnickiego i Ostrawsko-Karwińskiego Zagłębia Węglowego. Badania prowadzono w ramach projektu Environmental studies in the South of Poland using nuclear and related analytical techniques.

We have compared historical changes in concentrations of the heavy metals Mn, Ni, Cu, Zn, Cd and Pb accumulated in samples from the Polish woodlands of Beskidy and Karkonosze (S, SE Poland) and the north-east regions of the country, versus the relatively little polluted areas of Spitsbergen of the Svalbard Archipelago. We have combined the results from literature with new results from 2014. The regions of Beskidy and Karkonosze were the most exposed to heavy metals deposition. However, from 1975 to 2014 there was a considerable decrease of concentrations of Cu, Zn, Cd and Pb at all Polish sites, clearly signifying improvement of environmental quality. For example, the average Cd concentration in mosses samples collected in Karkonosze decreased from 0.002 mg/g in 1975 to 0.0006 mg/g in 2014. It is interesting to observe relatively large concentrations of nickel in moss samples collected in 2014 in the Svalbard archipelago, in the vicinity of Longyearbyen (average 0.018 mg/g) which most likely originate from local mine waste piles.
