“…T. aestivum was selected to represent sensitive test species, based on its use in previous phytotoxicological studies (Kukier and Chaney 2001;Maliszewska-Kordybach and Smreczak 2003). Deschampsia caespitosa was chosen as it is a grass native to the Athabasca oil sands region, with possible tolerances to some heavy metals, such as nickel, which may be present in coke (Kuja and Hutchinson 1979).…”

Over the past decades, the global production of petroleum coke, a by-product of the oil sand industry, has increased with the growing importance of oil sands as a source of fossil fuels. A greenhouse study using Triticum aestivum and Deschampsia caespitosa was conducted to assess the growth and physiological effects of coke on plants. The plants were grown in cokes with or without a cap of peatmineral mix and were compared to plants grown in a peat-mineral mix (control). Our results indicate that the selected plants can survive in coke; however, stress symptoms such as reductions in transpiration (45-91%) and stomatal conductance rates (44-92%) in T. aestivum, biomass in T. aestivum (5-83%) and D. caespitosa (43-90%), photosynthetic pigments in T. aestivum (32-68%) and D. caespitosa (33-44%) and proline concentrations in D. caespitosa (77-97%) were observed. Furthermore, potentially phytotoxic concentrations of nickel (47-69 μg g −1 in D. caespitosa) and vanadium (9.3-18.3 μg g −1 in T. aestivum and 4-27.8 μg g −1 in D. caespitosa) were found in some tissues while molybdenum accumulated in D. caespitosa shoots at concentrations reported, in other studies, to cause molybdenosis in ruminants. These results suggest that the plants growing in coke could experience multiple stresses including water stress, nutrient deficiencies and/or Ni and V toxicity. Capping coke with peat-mineral mix limited the stress symptoms and could improve revegetation success of coke impoundment sites. This study provides baseline data for future long-term field studies essential for developing coke management guidelines.

“…These elements exhibit various proprieties in soils including differences in mobility and bioavailability, although leaching losses and plant uptake are usually relatively small compared with the total quantities entering the soil from different sources. In the long term, this can lead to heavy metal accumulation that could affect the quality of the agricultural soils, leading to phytotoxicity at high concentrations, the maintenance of soil microbial processes and the transfer of toxic elements to the human diet as a result of increased crop uptake or soil ingestion by grazing livestock (Nicholson et al 2003;Wong et al 2002;Manz et al 1999;Maliszewska-Kordybach and Smreczak 2003;Kim and Kim 1999). Therefore, heavy metal reduction in the soils is a strategic aim in soils protection policies being implemented in Italy and in the European Union (EU 2008).…”

The aim of this paper is to evaluate total and bioavailable concentration of heavy metals in agricultural soils in order to estimate their distribution, to identify the possible correlations among toxic elements and the pollution sources, to distinguish the samples in relation to sampling site or to sampling depth, and to evaluate the available fraction providing information about the risky for plants. In particular, we reinvestigated total concentrations of As, Be, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sb, V, and Zn and available concentrations of As, Be, Cd, Cr, Cu, Hg, Ni, Pb, Sb, and Zn in soil from Apulia (Southern Italy). Analytical results showed that total concentrations, for all soils, are in the range permitted by regulations in force in Italy, but some soils evidence slight enrichment of Cd, Cr, Cu, Pb, and Zn. All the heavy metals in the available fraction were below the detection limits of the analytical techniques used except Cu, Ni, Pb, and Zn.

“…Maliszewska-Kordybach and Smreczak (2003) found that the deleterious influence on soil microorganism activity was more marked in the case of soils contaminated with both groups of these pollutants than in soil amended with heavy metals or PAH alone. However, the impact of the negative effects on the soil microbial community in the degradation of PAH has only recently been emphasized (Sokhn et al 2001;Wong et al 2005) and the influence on biological remediation of heavy metals has not been well documented.…”

“…These ubiquitous organic pollutants exhibit strong carcinogenic and toxic properties (Maliszewska-Kordybach and Smreczak 2003). It is estimated that more than 90% of the total burden of PAH resides are in the surface soils, where most of these compounds accumulate (Wild and Jones 1995).…”

“…The microbial degradation of PAH has received a great deal of attention as a possible strategy for the bioremediation of PAH-contaminated soils (Johnsen et al 2002). However, soils contaminated with PAH often contain high levels of other pollutants such as heavy metals, which are often derived from the same sources as PAH (Maliszewska-Kordybach and Smreczak 2003).…”

Dynamics of microbial community during bioremediation of phenanthrene and chromium(VI)-contaminated soil microcosms

et al. 2008

The combined effect of phenanthrene and Cr(VI) on soil microbial activity, community composition and on the efficiency of bioremediation processes has been studied. Biometer flask systems and soil microcosm systems contaminated with 2,000 mg of phenanthrene per kg of dry soil and different Cr(VI) concentrations were investigated. Temperature, soil moisture and oxygen availability were controlled to support bioremediation. Cr(VI) inhibited the phenanthrene mineralization (CO(2) production) and cultivable PAH degrading bacteria at levels of 500-2,600 mg kg(-1). In the bioremediation experiments in soil microcosms the degradation of phenanthrene, the dehydrogenase activity and the increase in PAH degrading bacteria counts were retarded by the presence of Cr(VI) at all studied concentrations (25, 50 and 100 mg kg(-1)). These negative effects did not show a correlation with Cr(VI) concentration. Whereas the presence of Cr(VI) had a negative effect on the phenanthrene elimination rate, co-contamination with phenanthrene reduced the residual Cr(VI) concentration in the water exchangeable Cr(VI) fraction (WEF) in comparison with the soil microcosm contaminated only with Cr(VI). Clear differences were found between the denaturing gradient gel electrophoresis (DGGE) patterns of each soil microcosm, showing that the presence of different Cr(VI) concentrations did modulate the community response to phenanthrene and caused perdurable changes in the structure of the microbial soil community.
