The profitable use of sewage sludge in agriculture as fertilization, depend upon the content of chemicals as well as the pathogenic microorganisms. In our investigation was shown, that energetic willow don't favour adaptation of pathogenic microorganisms in ryzosphere. The sanitary investigation of soil samples shown, that bacteria from genera Salmonella, Shigella, Staphylococcus and other from family of Enterobacteriaceae as well as the parasites eggs of Ascarius, Trichuris and Toxacaria introduced to soil environment with sewage sludge are very quickly eliminated from soil. The dangerous parasites and pathogenic bacteria gone in investigated soil in period about 3 mounts.

W pracy przedstawiono wyniki badań dotyczących występowania i rozprzestrzeniania się mikroorganizmów wokół składowisk odpadów komunalnych. W wyniku ponad dziesięcioletnich badań mikrobiologicznych wykazano, że obiekty komunalne są źródłem bioaerozolu, z którego wyizolowano ponad 50 saprofitycznych i chorobotwórczych bakterii i promieniowców oraz 58 gatunków grzybów głównie z klasy Deuteromycetes. Dominującymi rodzajami bakterii były Bacillus, Micrococcus, Pseudomonas, Mycobacterium, Streptococcus, Staphylococcus i Streptomyces. Natomiast wśród wyizolowanych grzybów dominowały rodzaje: Alternaria, Aspergillus, Cladosporium, Fusarium, Penicillium i Verticillium. Jako niebezpieczne okazało się występowanie w badanym powietrzu groźnych grzybów toksynotwórczych należących do gatunków: Aspergillus jlavus, Aspergillus ochraceus, Fusarium nivale, Fusarium oxysporum, Penicillium rubrum, Penicillium rugulosum i Scopulariopsis charta rum. Niektóre z wyizolowanych gatunków drobnoustrojów okazały się typowe dla odpadów, stąd można na podstawie składu mikrobioceno- tycznego powietrza atmosferycznego ocenić zasięg oddziaływania i rozprzestrzenianie się mikroorganizmów ze składowisk na okoliczne tereny.

Ten year investigations of various municipal waste dumps showed that both, the old and new dumps are an abundant source of microorganisms. Over 50 species of saprophytic and pathogenic bacteria and actinomycetes and 58 species of moulds mainly from the class of Deuteromycetes, were isolated. In the air samples dominating were bacteria from the genera: Bacillus, Micrococcus, Pseudomonas, Mycobacterium, Streptococcus, Staphylococcus and Streptomyces. Among isolated moulds the following genera of fungi: Alternaria, Aspergillus, Cladospo- rium, Fusarium, Penicillium and Verticillium were dominant. The toxin-producing fungi from the species of Aspergillus flavus, Aspergillus ochraceus, Fusarium nivale, Fusarium oxysporum, Penicillium rubrum, Penicillium rugulosum and Scopulariop- sis chartarum were found. Some species of microorganisms appeared to be specific to waste dump environment, so their expansion around the dumps and maximum range of occurrence and dispersal could be measured.

Aluminium is an element commonly occurring in nature, the third most abundant in the earth's crust after oxygen and silicon. It forms numerous mineral and organic complexes, characterised by different degrees of hydration. Its easy transition from solid to liquid phase and high solubility in acid environment are decisive factors for its important function in the environment. Until recently, aluminium was considered harmless for the human organism as it is readily excreted through urine. However, studies of environmental toxicology conducted in recent years indicated that aluminium could be a cause of many diseases in humans, animals and plants. Acid rains and increasing acidification of the environment induced water and soil pH changes which resulted in the mobilisation of toxic aluminium ions which in turn evoked many unfavourable alterations, such as plant poisoning, forest drying, crop reduction, vanishing of water fauna, and numerous disturbances in the function of human and animal organisms. Aluminium can be found in many food products and feed for animals. In this way it enters the organism and accumulates in various tissues. Although the mechanism of toxic aluminium actions on humans has not been elucidated yet, prophylactic action should be undertaken aimed at limiting the contact of humans with aluminium. Most of all, it should be eliminated from food, food additives and medicines. We should avoid tools, kitchen utensils and appliances made of aluminium as well as aluminium wrappings and containers.
