    Activity of soil enzymes is considered as a good indicator of natural and anthropogenic disturbances of the functioning of the soil. Heavy metals can inhibit the activity of enzymes in varying degree, depending on soil properties such as content of clay materials, organic matter and pH of soil solution. The aim of this study was to determine the effect of physicochemical and biological properties of soils on the condition of Norway spruce stands in Silesian Beskid. In the soil samples enzymatic activity of four enzymes (alkaline and acid phosphatase, dehydrogenase and urease) and concentration of three selected heavy metals (Cd, Pb, Zn) and sulfur were determined. The analyses showed no reduced activity of investigated enzymes. Presumably, despite of low pH values of the soil, organic matter contained in the soil is able to effectively bind heavy metal ions, limiting their cycling in the environment. It can be concluded that the condition of spruce stands in Silesian Beskid is not affected by the soil contamination

    The aim of this study was to determine the suitability of chosen organs of Robinia pseudoacacia as bioindicators. Content of selected elements in leaves, shoots, seeds, pods and bark of R. pseudoacacia from the area of three cities of Silesia province: Katowice, Chorzow and Siemianowice Slaskie was estimated. In each of the cities five sampling points were selected. Localizations were grouped in three categories differing in terms of the level of pollution (traffic, industrial plants). Statistically significant differences between pollution level of segregated groups in investigated localizations were found. On the basis of PCA and cluster analysis for individual organs sampling points were divided into groups depending on concentration of investigated elements in tissues of R. pseudoacacia. Conducted studies suggest that the organ best suitable for bioindication are leaves of R. pseudoacacia

    Ocena aktywno艣ci zanieczyszcze艅 glebowych jako wska藕nika wp艂ywu zanieczyszcze艅 antropogennych na funkcjonowanie ekosystem贸w las贸w 艣wierkowych Beskidu 艢l膮skiego

    Aktywno艣膰 enzym贸w glebowych uwa偶ana jest za dobry wska藕nik naturalnych i antropogennych zaburze艅 w funkcjonowaniu gleby. Metale ci臋偶kie w r贸偶nym stopniu mog膮 hamowa膰 dzia艂anie enzym贸w, w zale偶no艣ci od w艂a艣ciwo艣ci gleb, takich jak zawarto艣膰 materia艂贸w ilastych, gliny, materii organicznej czy warto艣ci pH roztworu glebowego. Celem pracy by艂o okre艣lenie wp艂ywu w艂a艣ciwo艣ci fizykochemicznych i biologicznych gleb na kondycj臋 drzewostan贸w 艣wierkowych w Beskidzie 艢l膮skim. Pr贸bki glebowe zbadano pod wzgl臋dem aktywno艣ci enzymatycznej (fosfataza kwa艣na i zasadowa, dehydrogenaza, ureaza) oraz koncentracji trzech wybranych metali ci臋偶kich (Cd, Pb, Zn) i siarki. Analizy nie wykaza艂y obni偶onej aktywno艣ci badanych enzym贸w. Prawdopodobnie mimo niskich warto艣ci pH gleby, zawarta w niej materia organiczna efektywnie wi膮偶e metale ci臋偶kie, ograniczaj膮c ich obieg w 艣rodowisku. Mo偶na stwierdzi膰, 偶e stan drzewostan贸w 艣wierkowych w Beskidzie 艢l膮skim nie ma zwi膮zku z zanieczyszczeniem gleb na tym terenie
