The level of pollution with petroleum compounds was evaluated in Suplacu de Barcău area based on the assessment of total petroleum hydrocarbons (TPH) concentrations in soil. As source of contamination, one active and another inactive petroleum extraction wells were chosen, and the concentrations were determined by fluorescence spectrometry. The results indicated alarming exceedances of the intervention thresholds, especially in the area where the activity is stopped, thus indicating long-term accumulation of pollutant and persistence in soil.

Heavy Duty Diesel

Total petroleum hydrocarbons pollution of soil samples randomly collected from three Nigeria Universities in Port Harcourt due to the use of heavy-duty diesel generators was studied to ascertains the level of concentration of the different hydrocarbons’ categories. The soil samples were collected at two different depths of 0.00-0.50m and 0.50-1.00m. The Universities were Ignatius Ajuru University of Education (IAUE), Rivers State University (RSU) and University of Port Harcourt (UNIPORT). The different total petroleum hydrocarbons categories were Gasoline Range Organics (GRO), Diesel Range Organics (DRO) and Lube Oil Range. Soxhlet extraction method was used in extracting the samples and due column clean-up was performed for chromatographic analysis. Gas Chromatography-Flame Ionization Detector was used to determine the level of concentrations of the different categories of total petroleum hydrocarbons. The results showed that at 0.00-0.50m depth, IAUE was 4.42145, 945.4784, and 525.66919 mg/Kg for GRO, DRO and lube oil range respectively, RSU was not detected, 494.44799 and 458.6715 mg/Kg for GRO, DRO and lube oil range respectively and UNIPORT was 4.40920, 501.2246 and 467.71426 mg/Kg for GRO, DRO and lube oil range respectively. At 0.50-1.00m depth IAUE was 2.75132, 596.35126, and 311.84451 mg/Kg for GRO, DRO and lube oil range respectively, RSU was not detected, 298.06899 and 270.61619 mg/Kg for GRO, DRO and lube oil range respectively and UNIPORT was 2.77780, 301.74701 and 276.88684 mg/Kg for GRO, DRO and lube oil range respectively. The level of soil contamination Showed that GRO > DRO > lube oil range. The observation showed that hydrocarbon pollution decreased with increase in depth. The level of DRO and lube oil range in the studied areas exceeded the limit acceptable and therefore adequate steps should be taken to remedy the situation so that it will not pose any health hazard to the workers operating the heavy-duty generators.

The Impact

The effect of compost on phytoremediation of diesel-contaminated soils was investigated using 130 small (200 g) containers in two screening tests. The experiments were conducted in a controlled environment using ryegrass from seed. Containers were destructively sampled at various times and analyzed for plant mass and total petroleum hydrocarbons. The results indicate that the presence of diesel reduces grass growth, and that compost helps reduced the impact of diesel on grass growth. The addition of compost helps increase diesel loss from the soils both with and without grass, though the addition of grass leads to lower diesel levels compared with controls. A second set of experiments indicates that the compost helps in phytoremediation of diesel-contaminated soil independent of the dilution effect that compost addition has. The results indicate that the compost addition allowed diesel loss down to 200 mg TPH/kg even though the compost would be expected to hold the diesel more tightly in the soil/compost mixture. The simplicity of the screening tests led to difficulties in controlling moisture content and germination rates. The conclusion of the research is that the tilling of compost into soils combined with grass seeding appears to be a valuable option for treating petroleum-contaminated soils.

<p>La electrobiorremediación es la técnica híbrida que suma los efectos de la electrorremediación a la degradación bacteriana de diferentes contaminantes. El objetivo de este estudio fue utilizar esta técnica para aumentar la biodisponibilidad de los hidrocarburos presentes en un suelo con contaminación antigua y su eliminación. El experimento duró 63 días y se realizó en una cuba de vidrio con tres compartimentos comunicados por puentes salinos de buffer fosfato que permitieron establecer la diferencia de voltaje y mantener el pH del suelo en valores óptimos para la vida bacteriana. Se determinaron: pH,  humedad, hidrocarburos totales del petróleo (TPH) y bacterias.

Environmental pollution is a global problem, while bioremediation technology removes pollutants from the environment using microorganisms. This study was aimed at investigating how a bioremediation process affected soil humification. In soil polluted with petroleum and its derivatives that was submitted to bioremediation, besides the total petroleum hydrocarbons and the number of microorganisms, quantitative and qualitative changes of isolated humic acids were determined during the process. The bioremediation of 150 m3 of polluted soil lasted 150 days. The level of total petroleum hydrocarbons decreased by 86.6 %, while the level of humic acids increased by 26.5 %. The elemental analysis showed the reduction of C and the H/C ratio and the increase of O and the O/C ratio of isolated humic acids during the process. The ratio of absorbencies at 465 and 665 nm also increased. Based on this and the Fourier-transform infrared spectra, it was shown that the humic acids isolated at the end of bioremediation were enriched with oxygen functional groups and aromatic structures. This study provides one of the first insights into the relationship between bioremediation and humification, as well as evidence of how hydrocarbon-degrading microorganisms have a significant influence on changes to humic acid structure during bioremediation.
