“…An important target for future research is the identification of polycyclic aromatic hydrocarbons (PAHs) because one potential for PAHs release is from oil fields where production pits contain a mixture of crude oil, corrosion inhibitors, de-emulsifying chemicals and salt water. Among hydrocarbons, (PAHs) have been recommended as priority pollutants by the United States Environmental Protection Agency (USEPA) and are target components for study in oil-contaminated sites due to their carcinogenic, mutagenic and toxic properties (BARTON & al [33]; DUGAY & al [34]; KE & al [35]; MAILA & CLOETE [36]; GAO & ZHU [25]; HUANG & al [26]; HE & al [37]; LIU & al [38]).…”

Oil spill represents the release of a liquid petroleum hydrocarbon (including its volatile fraction) into the environment, due to human activities like tankers, oil wells, off shore and terrestrial oil platforms. The goal of this paper was to identify potentially useful plant indicator species for ecological restoration and remediate of oil contaminated soils. The use of plant-based system to remediate contaminated soils has become an area of intense scientific study in recent years and it is apparent that plant which grow well in contaminated soils need to be identified and screened for use in phytoremediation technologies. Therefore, in this study the effect of crude oil on germination and seedling emergence of selected plant species was investigated.The objective was to determine if crude oil exerts detrimental effect to plants during early critical stages in their development. The detrimental effect growth was compared to the control after 14 days. Three grass species were tested: Festuca pratensis, Lolium perenne and Poa pratensis. We measured plant height, root length, and plant dry weight. Visual phyto-toxicity was also recorded in a laboratory experiment where seeds that germinated were photographed and morphological parts measured. In contaminated soil that was air-dried at 30°C and volatile compounds lost during the preparation of treatments, the inhibition effect was insignificant. The results indicate that the volatile compounds exert a significant inhibition effect on seed germination and seedling emergence compared tocrude oil. A concentration of 8 mg oil/g soil determined a decrease of about 50% of the biomass and a concentration of 32 mg oil/g soil a decrease of seed germination rate to about 50% for Poa pratensis. In this case the range 64-128 mg oil/g soil is critical to determine the EC50. The soil analyses indicated a content of sand (46%), silt (46%), clay (8%), TN (0.91± 0.12 mg/g dry soil), TP (0.26±0.08 mg/g dry soil), TK (6.81± 0.56 (mg/g dry soil); anda higher pollution with Total Petroleum Hydrocarbons TPH (C10-C40) (20 mg/g soil) at Ţintea site.

“…Una respuesta similar registró Zand, Bidhendi y Mehrdadi (2013) explican que una producción de materia vegetal continua, puede ser efectiva, no solo por la prospección de las raíces, sino por los exudados radicales que mejoran la actividad catabólica de los microorganismos de la rizósfera. Así mismo, las condiciones de anegamiento permiten el aumento de la materia vegetal por el transporte de material fotosintético a las raí-ces, esto favorece el crecimiento y desarrollo del tejido fotosintético (Liu, Jadeja, Zhou, & Liu, 2012;Ciotti, Castelán, Hack, Porta, & González, 2014). El crecimiento y desarrollo vegetal de L. hexandra estimuló la actividad metabólica de los microorganimos, que pudo generar el proceso de óxido-reducción de los hidrocarburos del PF y PI en la rizósfera (Khan, Afzal, Iqbal, & Khan, 2013).…”

Use of Leersia hexandra (Poaceae) for soil phytoremediation in soils contaminated with fresh and weathered oil. The oil industry has generated chronic oil spills and their accumulation in wetlands of the state of Tabasco, in Southeastern Mexico. Waterlogging is a factor that limits the use of remediation technologies because of its high cost and low levels of oil degradation. However, Leersia hexandra is a grass that grows in these contaminated areas with weathered oil. The aim of the study was to evaluate the bacteria density, plant biomass production and phytoremediation of L. hexandra in contaminated soil. For this, two experiments in plastic tunnel were performed with fresh (E1) and weathered petroleum (E2) under waterlogging experimental conditions. The E1 was based on eight doses: 6 000, 10 000, 30 000, 60 000, 90 000, 120 000, 150 000 and 180 000 mg.kg -1 dry basis (d. b.) of total petroleum hydrocarbons fresh (TPH-F), and the E2, that evaluated five doses: 14 173, 28 400, 50 598, 75 492 and 112 142 mg. kg -1 d. b. of total petroleum hydrocarbons weathered (TPH-W); a control treatment with 2 607 mg.kg -1 d. b. was used. Each experiment, with eight replicates per treatment, evaluated after three and six months: a) microbial density of total free-living nitrogen-fixing bacteria (NFB) of Azospirillum (AZP) and Azotobacter group (AZT), for viable count in serial plate; b) dry matter production (DMP), quantified gravimetrically as dry weight of L. hexandra; and c) the decontamination percentage of hydrocarbons (PDH) by Soxhlet extraction. In soil with TPH-F, the NFB, AZP y AZT populations were stimulated five times more than the control both at the three and six months; however, concentrations of 150 000 and 180 000 mg.kg -1 d. b. inhibited the bacterial density between 70 and 89 %. Likewise, in soil with TPH-W, the FNB, AZP and AZT inhibitions were 90 %, with the exception of the 14 173 mg.kg -1 d. b. treatment, which stimulated the NFB and AZT in 2 and 0.10 times more than the control, respectively. The DMP was continued at the six months in the experiments, with values of 63 and 89 g in fresh and weathered petroleum, respectively; had no significant differences with the control (p≤0.05). The PDH reached values of 66 to 87 % both TPH-F and TPH-W at six months, respectively. These results demonstrated the ability the L. hexandra rhizosphere to stimulate the high NFB density, vegetal biomass production and phytoremediation of contaminated soils (with fresh and weathered petroleum), in a tropical waterlogging environment.

“…Thus, the microorganisms associated with the plants have been found to increase the removal of petroleum hydrocarbons from contaminated soil (Qiu et al, 1997;Pradhan et al, 1998). Some studies (Liu et al, 2012;Cui et al, 2013) have examined the possibility of using ornamental plants for phytoremediation of petroleum-contaminated soils. This has an advantage of beautifying the neighbouring environment.…”

Existing information relating to the application of phytoremediation in arid regions, for mitigating the toxicity of organic and inorganic contaminants is summarized, emphasizing the comparative merits of different phytostrategies. Adverse climatic conditions in arid and semi-arid environments along with the intrinsic abiotic stresses need specific considerations, which are discussed here. The current "state of art" for petrochemical and metal phytoremediation, as well as phytodesalination is presented, making it possible to choose the very best decision, when the technology is applied for various contaminant scenarios. Information is also provided on contaminants in arid regions, remediation approaches and different phytoremediation strategies to be adopted, depending on the nature of contaminants and the site situations. Furthermore, phytodesalination may well occur in parallel with phytoremediation of heavy metal polluted soils in arid regions, enhancing the potential of this process. This has drawn a great deal of interest during recent years and is reviewed here. Finally, the lacunae in the current knowledge are identified, which has to be addressed to improve the effectiveness of phytoremediation under arid conditions.
