The objective of the experiment was to evaluate the energy efficiency of the phytoremediation process, supported using energy crops. The scope of conducted work includes the preparation of a field experiment. During the evaluation, 2 factors were into consideration – total energy demand and total energy benefit. The case study, used as an origin of data, consists a 3-years field study, conducted with the use of 2 energy crops – Phalaris arundinacea L. and Brassica napus L. The area subjected to the experiment was polluted with polycyclic aromatic hydrocarbons (PAHs) and herbicides, classified as phenoxy acids (2, 4 D). The experimental design consisted of 4 groups of fields, divided according to the used plant species and type of treatment. For each energy crop, 2 types of fertilization strategies were used. Therefore the 1st and 3rd sets of fields were not treated with any soil amendment while the 2nd and 4th sets were fertilized with compost. The obtained data allowed to observe that the cultivation of P. arundinacea L. and B. napus L. allowed a positive energy balance of the process to be achieved. However, it should be noted, that the B. napus L. growth in the first vegetation season was not sufficient to fully compensate a total energy demand. Such a goal, in the mentioned case, was possible after the 2nd vegetation season. The collected results show also that the best energetic potential combined with the most effective soil remediation were obtained on the fields with the cultivation of P. arundinacea L. fertilized with compost. The number of biofuels, collected from the 1 ha of such fields, can reach a value equal even to12.76 Mg of coal equivalent.

W latach 2000-2002 badano niektóre naturalne i antropogenne właściwości wód powierzchniowych Kampinoskiego Parku Narodowego. Uzyskane wartości średnie omówiono w porównaniu do odpowiednich norm. Analizy większości próbek wykazały, że odpowiadają one I klasie czystości. Benzo(a)pirenu nie wykryto. Jednak w dwóch przypadkach zaobserwowano wysokie stężenie żelaza i manganu. Próbki pobrane w listopadzie zawierały więcej manganu. W jednym przypadku oznaczono wysokie stężenie azotanów. Większość próbek pobranych w Aleksandrowie odpowiadała li klasie czystości ze względu na zawartość fosforanów.

The aim of this work is purification of contaminated soil from manufactured gas plants MGP, which arc not used. Prepared chromatographic methodologies, which allow qualitative identification and quantitative determination of individual aliphatic and aromatic (TAH, PAH) hydrocarbons in the soil from the selected MGP, arc presented. The results of the research on remediation of the soil polluted with petroleum hydrocarbons (TAH, PAHs) in semi-field conditions arc discussed. Application of basic biorcmcdiation and bioaugmcntation with indigenous microorganisms, enriched with PAH biodegradable fungi, resulted in reduction in amount of 5- and 6-polycyclic aromatic hydrocarbons. The research enables control of remediation progress, selection of optimal doses of biogenie compounds and determines the time of the process. The entire cycle of soil remediation was monitored with the use of gas chromatography (GC). Estimation ofbiodcgradation degree of individual aliphatic hydrocarbons (alkancs) was based on changes in their concentration in the soil and determined by biodegradation indicators: C,/pristanc and C,/phytanc ratios. Attention was paid particularly to biodcgradation of polycyclic aromatic hydrocarbons (PAH), which were observed in substantial concentrations in the polluted soil. The elaborated chromatographic methodology of PAH determination in the soil enabled estimation of a biodcgradation rate referring to individual compounds. Moreover, attempts to create a TAH biodcgradation model with the use of C30-l 7a(H),2 l l3(H)-hopanc were undertaken.
