Abstract	Abstract Selected parameters of sewage sludge from two different sewage treatment plants: a rural one (in Mrozy) and a municipal one (in Siedlce) were compared. Samples from a mechanical-biological sewage treatment plant (Mrozy) showed a higher content of nitrogen and lower content of phosphorus, potassium and magnesium than the samples from the sewage treatment plant with the tertiary enhanced nutrient removal (Siedlce). The C/N ratio was 7.5 and 11.7, respectively. No differences were noted in the content of zinc in analysed samples. From among analysed metals (Cu, Zn, Fe and Mg), magnesium occurred in the greatest amounts in easily available form. The presence of 137Cs was found in sewage sludge from both treatment plants. Streszczenie W pracy porównano skład chemiczny osadów ściekowych wytwarzanych w dwóch różnych oczyszczalniach ścieków: w oczyszczalni wiejskiej (Mrozy) i miejskiej (Siedlce). Ustalono, że próbki z oczyszczalni mechaniczno-biologicznej (Mrozy) charakteryzują się wyższą zawartością azotu, niższym poziomem fosforu, potasu i magnezu w porównaniu do próbek z oczyszczalni z podwyższonym usuwaniem biogenów (Siedlce). Stosunek C/N wynosił odpowiednio 7.5 do 11.7. Nie odnotowano różnic w zawartości cynku w badanych próbkach Spośród metali: Cu, Zn, Fe i Mg w największych ilościach w formach biodostępnych dla roślin występował magnez. W osadach z obu oczyszczalni odnotowano także obecność izotopu 137Cs.
