“…As a fuel spill ages, it changes the physicochemical and biological properties of soil, thereby altering the bioavailability and toxicity of contaminants [32]. Evaporation is responsible for the loss of the volatile components, typically the n-alkanes (n-C 9-14 ) and isoprenoids; leaching removes water soluble components (although with a limited effect on the bulk concentration of diesel due to the low solubility of bulk diesel compounds); and microbial degradation selectively transforms compounds based on their bioavailability.…”

“…For the purpose of the present study, aging refers to a change in the chemical composition and concentration of SAB in the soil from its original form through volatilization, biodegradation, and sorption and sequestration [32]. It is acknowledged that different degrees of aging exist, and the composition of the residuals will vary with time.…”

Abstract-Several fuel spills have occurred on subantarctic Macquarie Island (54830 0 S 158857 0 E) associated with storing fuel and generating power for the island's research station. The Australian Antarctic Division began full-scale, on-site remediation of these sites in 2009. To develop appropriate target concentrations for remediation, acute and chronic tests were developed with the endemic earthworm, Microscolex macquariensis, using avoidance, survival, and reproduction as endpoints. Uncontaminated low (3%), medium (11%), and high (38-48%) carbon content soils from Macquarie Island were used to examine the influence of soil carbon on toxicity. Soils were spiked with Special Antarctic Blend (SAB) diesel and used either immediately to simulate a fresh spill or after four weeks to simulate an aged spill. Earthworms were sensitive to fresh SAB, with significant avoidance at 181 mg/kg; acute 14-d survival median lethal concentration (LC50) of 103 mg/kg for low carbon soil; and juvenile production median effective concentration (EC50) of 317 mg/kg for high carbon soil. Earthworms were less sensitive to aged SAB than to fresh SAB in high carbon soil for juvenile production (EC50 of 1,753 and 317 mg/kg, respectively), but were more sensitive for adult survival (LC50 of 2,322 and 1,364 mg/kg, respectively). Using M. macquariensis as a surrogate for soil quality, approximately 50 to 200 mg SAB/kg soil would be a sufficiently protective remediation target.

“…Desorption in this case is the slow diffusion of large hydrocarbon molecules into the soil and/or entrapment of the slowly diffused molecules within small pores in the soil (Hatzinger & Alexander, 1995;Torres et al, 2005). Entrapment has been shown to be influenced by a number of factors, such as environmental conditions, contaminant properties, and soil properties, including organic content (Al-Zalzaleh & Shabbir 2004;Reeves et al, 2001;Scherr et al, 2007;Tang et al, 2012;Zhao et al, 2009).

Hydrocarbon oil-contaminated soil assessment using electrical resistivity topography

In Kuwait, oil wells exploded in 1991 have created numerous massive oil lakes, which have subsequently dried and contaminated the soil. A research project was initiated to delineate the type and extent of contaminated soil using an area survey method, namely Electrical Resistivity Topography (ERT), to examine dry oil lakes located in Bahra, Subiya. The specific objective was to assess the applicability of the environmentally friendly ERT to assist in the design of measures to remediate the contaminated land. ERT results were generated by testing a grid in both contaminated and non-contaminated areas. In addition, conventional soil boreholes were used to explore the sub-surface profile and depth of contamination in these areas for comparison with ERT results. In-situ and laboratory physical and chemical tests were performed on soil samples collected from the site to identify the contamination type and concentration as well as variation in the physical properties of the soil profile with depth. Results indicated the contamination depth to be 1.2 m from the ground surface. These results were also confirmed by borehole analyses (chemical and physical). Chemical tests indicated that the contamination consists of hydrocarbons. The findings demonstrate that ERT can be used to establish a baseline in the assessment of potential hydrocarbon-contaminated sites and is applicable for determining the type and depth of contamination without the need for expensive and tedious boreholes and in-situ and laboratory soil testing.
