Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks. The journal is indexed by Thomson Reuters services (Biological Abstract, BIOSIS Previews) and has an Impact Factor 2017 of 1.120


The aim of the work was to estimate the influence of plants mycorrhizas on the number of hydrocarbons degrading bacteria, saprophytic bacteria and molds fungi during the remediation of the soil samples contaminated with used engine oil. The investigation were carried out in laboratory conditions. Nine modifications of the soil substrate were prepared and divided into three groups: the first one - without used engine oil; the second one - with 10% (w/w) of used engine oil; the third one - with 25% (w/w) of used oil. In each group one sample was sown with ribwort, one was inoculated with living spores of mycorrhizal fungi and sown with ribwort, and the third one was left without plants and mycorrhizal fungi. The sample of the uncontaminated soil was the control. The investigation showed a significant effect of used engine oil, the presence of ribwort and mycorrhizal fungi on the number of soil microorganisms. The increase of the number of hydrocarbons degrading bacteria, in respect to the control sample was observed in the used engine oil contaminated samples. The seeding of soil samples with plants and additional inoculation with spores of mycorrhizal fungi stimulated the increase of the number of microorganisms in the all studied groups.
