The mainly purposes this paper to compare the atmospheric air contamination in different localities depending on the winter and summer season of the year, with use of the enrichment factor and the Principal Component Analysis. The lack of a clear correlation between the enriching coefficients of Pb and Cd as well Cr and Ni may indicate that over the town area masses of the air from different directions can displace and as well, some close range sources of contamination can effect it. At present, the ecotoxicological estimations established for particular contaminated areas should include the information of the similarities of metal occurrence on the base of PCA analysis.

The planthopper and leafhopper communities inhabiting various plant assemblages covering coal-mine dumps in the vicinities of Ruda Śląska city and Mikołów city (Upper Silesia, Poland; UTM CA46) are described. Plots , are described in details, with plant species and phytosociological groupment given, if possible. Dynamics of planthoppers and leafhoppers populations, dominance structure and diversity indices, constancy index are described and analyzed. Chorological composition, as well as ecological content of communities are discussed. Species composition similarity indices are also analyzed. List of 109 species recorded in analyzed plots is given. Two species recorded are new to Polish fauna: Mocydiopsis parvicauda RIB. and Psammotettix dubius OSS., and 15 species are new to fauna of Upper Silesia region: Cixius distinguendus KMB, Tachycixius pilosus (Ol.), Delphacodes venosus (germ.), Javesella salina (hpt), Oncopsis carpini (j. shlb.), Tremulicerus tremulae (estl.), Zyginidia scutellaris (h.-S.), Macrosteles sordidipennis (StAl), Doratura impudica horv., Rbytistylus proceps (KMB), Rhopalopyx preyssleri (H.-S.), Ophiola russeola (FALL.), Arocephalus languidus (FL.), Psammotettix sabulicola (Curt.) and Mocuellus metrius (Fl.).
