    Opis:
    The presented study concerns on isolation and identification of indigenous bacteria in total petroleum hydrocarbon (TPH) polluted soil.. The composite TPH polluted soil was collected from Wonocolo public oilfields, Indonesia.. Pour plate and plate count techniques were used to bacterial population analysis and enumeration, respectively. Two dominant bacterial colonies were isolated from 4.06x107 CFU/g population in polluted soil, then morphologically and biochemically were characterized using Microbact Identification Kits (MicrobactTM GNB12A and 12B). The identification of isolated bacteria was performed using Bergey’s Manual of Determinative Bacteriology. The results showed that the strains of bacteria are Bacillus sp. and B. cereus with probability of 72.00 and 77.00%, respectively. These strains potentially acted as biosurfactant producers and hydrocarbon degraders. Thus, biostimulation could be implemented to reduce the TPH levels in polluted soil at Wonocolo public oilfields.

    Opis:
    Oily sludge is categorized as one of the hazardous wastes that needs to be remediated in order to convert it into a non-toxic compound. Bioremediation involves microorganisms, such as fungi. In the present study, the indigenous oily sludge fungi, Penicillium chermesinum was used to assess the bioremediation. The aim of this study was to obtain the growth profile of Penicillium chermesinum Biourge in reducing the Total Petroleum Hydrocarbon (TPH) and Polycyclic Aromatic Hydrocarbons (PAH) compounds in oily sludge. A descriptive method was applied in this study that consists of the preparation stage and the biodegradation stage of oily sludge. Biodegradation process was performed by using the Solid State Fermentation methods during 15 days with the addition of 10% of fungi inoculum from the total of fermentation medium (100 g). The observed parameters are the TPH, PAH content, and fungi growth profile that were measured using the Gravimetric, GC/MS and TPC analysis. Our results showed that the TPH content was reduced 29.16% from the control. We identified two degraded PAH compounds, namely Azulene (C10) and Fluoranthene (C16).

    Opis:
    The paper presents the results of field and laboratory studies aimed at studying the processes of oil transformation in the soil under the influence of natural biological processes during a two-year period on artificially created old spills. The soil of the study area was characterized as meadow. The high toxic effect of oil was confirmed, which was expressed in the complete extinction of soil flora and fauna. Despite the low oil content in the soil (less than 5%), soil self-purification processes were not observed. Moreover, the high sorption properties of the soil, the violation of the water regime and the lack of aeration led to the “conservation” of oil and significantly slowed down the natural processes of its biodegradation. This was confirmed by a slight change in the content of oil products a year after the start of the experiment, as well as the presence of free oil in the pore space of the studied soil.

    Opis:
    Hassi Messaoud oil field is one of the most important fields in Algeria and the world, because it covers an important quantity of total Crude Oil Production in Algeria. Furthermore, two-thirds of this oil field is underexplored or not explored. Therefore, the drilling process of petroleum wells in this field is a continuous process that results in significant drilling waste. This implies that enormous noxious quantities of drilling waste are produced daily that require treatment via solidification/stabilization (S/S) process before being landfilled. These types of wastes have pollution concentration that significantly exceeds the safety standards. In this study, we focus on the factors affecting the solidification/stabilization treatment of the drill cuttings obtained from Hassi Messaoud oil field and the process optimization. The solidification/stabilization is performed using the cement as binder, and sand, silicate, organophilic clay and activated carbon as additives. The study has been divided into two steps: (i) Determining the optimum ratio of each element used in the S/S process for the organic element (hydrocarbon) elimination, (ii) Combining the optimum ratios found in the previous step to determine the optimal mixture. The obtained results in the first step showed that the optimum ratio for the cement-to-drill cuttings mass ratio is 0.09:1. For the additives-to-drill cuttings mass ratios are 0.04:1, 0.006:1, 0.013:1 and 0.013:1 for the sand, sodium silicate, organophilic clay and activated carbon, respectively. An optimum formula is found whose main finding shows that the hydrocarbon content of our sample is dropped from 9.40 to 1.999%. Many tests’ results such as matrix permeability, resistance to free compression and heavy metals rate before and after S/S process were investigated before landfilling. Besides that, in the light of outcomes achieved by this assessment, these harmful cuttings can be converted into a useful product that helps in reducing the environmental foot prints.

    Opis:
    Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

    The paper presents studies results of total petroleum hydrocarbon (TPH) contaminations migration in sandy formations on the post-industrial area in Katowice in aspect their horizontal migration between aeration and saturation zones. In all investigated soil samples were determined mineral oils (>C12), gasoline (C6-C12) and polycyclic aromatic hydrocarbons (PAH) content and were also defined coefficient of filtration. Both mineral oils and gasoline belongs to organic liquids group lighter than water. Researches were supplemented with simulation of ground and underground water contamination state, round investigated area and also migration of petroleum hydrocarbon (TPH) contaminations model in examined grounds. The correlation between seasonal position of underground water level and total petroleum hydrocarbon (TPH) contaminations content in ground vertical profile was also showed. Besides variations of filtration rate in relation to petroleum hydrocarbon (TPH), light non-aqueous phase liquids (LNAPL) contaminations content was presented, as well.

    Opis:
    Do oznaczania ropopochodnych (TPH) w próbkach środowiskowych najczęściej wykorzystuje się metodę chromatografii gazowej (GC) oraz spektrometrię w podczerwieni (IR). Metoda GC-FID jest preferowaną w oznaczeniach węglowodorów ropopochodnych (TPH). W pracy wykorzystano metodę chromatografii gazowej z detektorem jonizacji płomieniowej (GC-FID) w celu określenia zakresu metody, granicy wykrywalności (LOD) i oznaczalności (LOQ), wyznaczenia krzywych kalibracyjnych oraz odzysku dla próbek wzbogaconych. Dodatkowo zbadano dwie metody ekstrakcji: na zimno (20°C) i na ciepło (40°C). Dla obu metod obliczono stopnie odzysku na dwóch poziomach stężeń (2 i 20 mg/ml). Wyniki uzyskane z analizy odzysku wskazują, że zależy on od temperatury ekstrakcji. Najwyższe stopnie odzysku uzyskano dla metody na ciepło (40°C). Opracowana metoda GC-FID nadaje się do oznaczania TPH (C10-C40) w próbkach wody.
    Two main methods are usually used to determined TPH in environmental samples: gas chromatography (GC) and infrared spectrometry (IR). However GC-FID is preferred method to TPH determination. In this work gas chromatography with flame ionization detection (GC-FID) was used to quantify of method range, to determine the limit of detection (LOD) and the limit of quantification (LOQ), to prepare a calibration curves, to determine the TPH in water samples and recovery test in contaminated samples. Two extraction methods were also researched in this paper: cold method (20°C) and warm method (40°C). The recovery range was calculated for these two types of extractions. The results indicate that the recovery of TPH is dependent on the temperature of the extraction. The highest recoveries of TPH were obtained with warm method (40°C). The GC-FID method, used in this work, is an useful technique for the determination of TPH (C10-C40) in water samples.

    Opis:
    Sediment samples were collected from the coastal area of the Petrochemical Special Economic Zone of Musa Bay. The samples were analyzed to determine the degree of hydrocarbon contamination and identify the sources of PAHs which were evaluated by employing the ratios of specific PAHs compounds and principal component analysis (PCA). The levels of TPH concentration in the studied area were relatively moderate compared to the world-wide chronically oil-contaminated locations. The concentration of total PAHs was lower than those in other parts of the Musa Bay but approached the NOAA sediment quality guideline value.
