“…In order to create a mathematical model of hydrocarbon pollutant biodegradation during wastewater biotreatment, a C 30 ‐17α(H),21β(H)‐hopane (biodegradation resistant compound) was used to normalize analytical data of TPH, ΣnC 6 –nC 22 and ΣnC 23 –nC 34 concentration . The use of hopane as a biomarker allowed the elimination of analytical errors in quantitative determination.…”

BACKGROUND Exploitation of oil‐fields always faces problems with management of petroleum‐contaminated wastewaters. Wastewater, severely contaminated with petroleum hydrocarbons: total petroleum hydrocarbons (TPH, 340.7 mg L−1), benzene, toluene, ethylbenzene, xylene (BTEX, 5.52 mg L−1), phenols (2.95 mg L−1), and polycyclic aromatic hydrocarbons (PAH, 29.2 µg L−1), were pretreated on a flow‐line installation. The following processes were applied: flotation, coagulation with flocculation, sedimentation and filtration of sediments. Then a biological module with an active biopreparation (microbial consortium, based on non‐pathogenic indigenous bacteria and fungi) was used to remove extant hydrocarbons. RESULTS After wastewater pretreatment, TPH content decreased to 49.7 mg L−1. During biological treatment, petroleum contaminants (TPH, phenols, BTEX and PAH) were decreased by 89%, 69%, 62%, and 46%, respectively. Biodegradation reached 83–96% for nC11–nC22 and 34–68% for nC23–nC36 alkanes (more resistant). Microtox, MARA, Daphtoxkit and Ames test indicated that changes in toxicity were not strictly connected with the decrease in TPH contents, possibly due to the formation of toxic indirect metabolites during biodegradation. After treatment, wastewater had no toxic properties. CONCLUSION As results show, toxicological tests are an effective tool to monitor changes in toxicity during wastewaters treatment. This field scale study proved that combining physico‐chemical processes and biological treatment has high effectiveness in petroleum hydrocarbons removal. © 2014 Society of Chemical Industry

“…Skutkiem tych zmian może być obniżenie żyzno-ści gleb czy też, w najbardziej skrajnych przypadkach, degradacja. Odporność gleby na degradację spowodowaną obecnością zanieczyszczeń zależy od wielu czynników, między innymi: właściwości fizykochemicznych gleby, stężenia i jakości chemicznych zanieczyszczeń, zawartości związków biogennych (azotu, fosforu), odczynu (pH) gleby, obecności związ-ków organicznych, składu ilościowego i jakościowego mikroorganizmów obecnych w glebie [12][13][14][15][16]. Czynniki te wpływa-ją również na proces samooczyszczania skażonych gleb, któ-ry na ogół zachodzi bardzo wolno, może trwać nawet setki lat.…”

Ocena zmian toksyczności gleby skażonej niklem i substancjami ropopochodnymi w procesach fitoremediacji W artykule omówiono zagadnienia związane z oczyszczaniem gleb skażonych niklem i substancjami ropopochodnymi. Do oczyszczania skażonej gleby wytypowano technologię opartą na fitoremediacji wykorzystującej aktywność roślin z grupy hiperakumulatorów i naftofitów (Lettuce iceberg, Melilotus officinalis, Festuca arundinacea) do pobierania zanieczyszczeń przez system korzeniowy. Na podstawie badań laboratoryjnych określono zarów-no wpływ rodzaju fitoremedianta na proces oczyszczania gleby, jak i oddziaływanie obecności substancji ropopochodnych na proces oczyszczania gleby zanieczyszczonej niklem. Podjęcie się realizacji tego zadania wymagało wykorzystania metod badawczych obejmujących analizy fizykochemiczne i badania toksykologiczne gleb, do przeprowadzenia których zastosowano mikrobiotesty typu ToxKit. Po zakończeniu 6-miesięcznego procesu fitoremediacji wykonano analizę chemiczną materiału roślinnego, celem określenia zawartości niklu w części naziemnej i korzeniu wytypowanych do badań fitoremediantów. Na podstawie uzyskanych wyników sformułowa-no wnioski dotyczące zagadnień związanych z zastosowaniem fitoremediacji w procesie oczyszczania skażonych gleb w zależności od stężenia i rodzaju substancji toksycznej. Ponadto określono, jakie rośliny spośród badanych są najlepiej przystosowane do wzrostu na skażonym terenie oraz jaki wymierny skutek obniżenia zanieczyszczeń przy ich wzroście można osiągnąć.Słowa kluczowe: fitoremediacja, gleba skażona, nikiel, substancje ropopochodne, testy toksykologiczne. Evaluation of toxicity changes in soil contaminated with nickel and petroleum-derived substances in phytoremediation processesThe article discusses issues related to cleaning of soils contaminated with nickel and petroleum-derived substances. Technology based on phytoremediation process that exploits activity of plants from the hyperaccumulator and petroleum-resistant plants group (Lettuce iceberg, Melilotus officinalis, Festuca arundinacea) was selected to clean the soil. Based on laboratory tests the impact of both the type of phytoremediation on the process of cleaning the soil, as well as the impact of the presence of oil on the process of cleaning soil contaminated with nickel was determined.This task requires the use of research methods such as physiochemical analysis and soil toxicological studies that utilize ToxKit microbiotests. Biomass chemical analysis in order to determine the nickel content in the aerial parts and roots was performed at the end of a 6-month process. Based on the obtained results conclusions related to the application of phytoremediation in soil remediation cleaning process depending on the concentration of toxic substance were edited. The types of plants that best adapt to growing in the contaminated area and reduction in the level of contamination due to their growth was also described in the article.

“…However, to a large extent they were dispersed and resulted in vast pollution of all ecosystems [5]. The most alarming adverse PCBs property is their tendency to bioaccumulate in lipid tissues and organic components of the soil and in fat tissues of animals and Biodegradation of petroleum pollutants in a historically polluted soil originating from waste pits with the use of a defined mixed culture based on non-pathogenic indigenous bacterial strains was studied by the authors, which is proven by numerous papers [39,[49][50][51].…”

Biodegradation is one of the most effective and profitable methods for the elimination of toxic polychlorinated biphenyls (PCBs) and total petroleum hydrocarbons (TPH) from the environment. In this study, aerobic degradation of the mentioned pollutants by bacterial strains Mycolicibacterium frederiksbergense IN53, Rhodococcus erythropolis IN129, and Rhodococcus sp. IN306 and mixed culture M1 developed based on those strains at 1:1:1 ratio was analyzed. The effectiveness of individual strains and of the mixed culture was assessed based on carried out respirometric tests and chromatographic analyses. The Rhodococcus sp. IN306 turned out most effective in terms of 18 PCB congeners biodegradation (54.4%). The biodegradation index was decreasing with an increasing number of chlorine atoms in a molecule. Instead, the Mycolicobacterium frederiksbergense IN53 was the best TPH degrader (37.2%). In a sterile soil, contaminated with PCBs and TPH, the highest biodegradation effectiveness was obtained using inoculation with mixed culture M1, which allowed to reduce both the PCBs (51.8%) and TPH (34.6%) content. The PCBs and TPH biodegradation capacity of the defined mixed culture M1 was verified ex-situ with prism method in a non-sterile soil polluted with aged petroleum hydrocarbons (TPH) and spent transformer oil (PCBs). After inoculation with mixed culture M1, the PCBs were reduced during 6 months by 84.5% and TPH by 70.8% as well as soil toxicity was decreased.
