mutagenic activity of studied compounds both in the presence (+S9) and in the absence (-S9) of an exogenous source of metabolic activation. The compounds were also tested in an in vitro chromosome aberration assay in which V-79 cells were exposed to the phenanthrene derivatives investigated both in the presence and in the absence of metabolic activation. The phenylphenanthrenes showed no mutagenic effect. These compounds occasionally induced significant decrease in the number of revertants in the Ames test. The greatest mutagenic effects were observed for 1-methylphenanthrene after metabolic activation (+S9). In the micronucleus test the greatest mutagenic effect was observed for 4-methylphenanthrene also in the presence of metabolic activation system. The results obtained are comparable to those reported earlier for the methylphenanthrenes. Assessment of mutagenic activity of methyland phenylphenanthrenes based on Salmonella test and micronucleus test

Currently in Poland the most widely used material for the production of electricity is fossil fuels. However, due to an increase in their prices and the tightening of European Union regulations on emissions of greenhouse gases, there are tendencies to transform the energy sector through the implementation of technologies based on alternative source of energy. The main focus is, therefore, on renewable energy source. In recent years, Poland has increased interest in the investments in renewable energy sources to fulfill the guidelines of the EU energy policy, which obliges Poland to obtain a 15% share of renewable energy sources in final energy consumption by 2020. One of the preferred state policy activities related to the production of energy from renewable sources is biogas production and cogeneration of electricity
