“…(Tables and 2). These values were higher than those reported by Barnier et al (2014) in their assessment of the desorption kinetics of PAHs from aged industrial soils using the Tenax extraction method, but even higher values for the rapidly desorbing fractions have been reported for the desorption kinetics of spiked phenanthrene and benzo(a)pyrene from soils (Rhodes et al, 2010;Spasojevic et al, 2015). Values of F rap for 5and 6-ring PAHs were significantly lower than those for the 3-and 4-ring PAHs.…”

“…Biological methods are traditionally regarded as the most appropriate methods for quantifying bioavailability, but their application may be time consuming and laborious, and the results are species dependent (Cui et al, 2013). With this in mind, a large number of efficient and cost-effective chemical methods have been developed to estimate the bioavailability of PAHs (Bergknut et al, 2007;Gomez-Eyles et al, 2011;Spasojevic et al, 2015). Two major processes, bioaccessibility and chemical activity, control the physicochemical component of bioavailability (Reichenberg and Mayer, 2006).…”

The aim of this study was to demonstrate the variations in bioavailability remaining in industrial and agricultural soils contaminated by polycyclic aromatic hydrocarbons (PAHs) after bioremediation. After inoculation of Mycobacterium sp. and Mucor sp., PAH biodegradation was tested on a manufactured gas plant (MGP) soil and an agricultural soil. PAH bioavailability was assessed before and after biodegradation using solid-phase extraction (Tenax-TA extraction) and solid-phase micro-extraction (SPME) to represent bioaccessibility and chemical activity of PAHs, respectively. Only 3- and 4-ring PAHs were noticeably biodegradable in the MGP soil. PAH biodegradation in the agricultural soil was different from that in the MGP soil. The rapidly desorbing fractions (F(rap)) extracted by Tenax-TA and the freely dissolved concentrations of 3- and 4-ring PAHs determined by SPME from the MGP soil decreased after 30 days biodegradation; those values of the 5- and 6-ring PAHs changed to a lesser degree. For the agricultural soil, the F(rap) values of the 3- and 4-ring PAHs also decreased after the biodegradation experiment. The Tenax-TA extraction and the SPME have the potential to assess variations in the bioavailability of PAHs and the degree of biodegradation in contaminated MGP soils. In addition, Tenax-TA extraction is more sensitive than SPME when used in the agricultural soil.

“…In response to the limitations of bioassays, in the past few years several efficient and cost-effective chemical methods have been developed to predict PAH bioavailability to bacteria, earthworms, and plants, including the use of semipermeable membrane devices (SPMDs) (Tao et al 2009, Wang et al 2015, solid-phase micro-extraction (SPME) (Jonker et al 2007, Van der Wal et al 2004), supercritical carbon dioxide extraction (Kreitinger et al 2007), and extraction with Tenax (Li et al 2015, You et al 2011) and cyclodextrin (Spasojevic et al 2015). Among these, the measurement of chemical activity (freely dissolved chemical concentrations) by SPME and the estimation of bioaccessibility (rapidly desorbing fraction) by Tenax-TA extraction have been successfully applied to predict the bioavailability of contaminants in organisms under laboratory conditions (Bielska et al 2014, Liu et al 2011, Yang et al 2013.…”

The aims of this study were to evaluate the bioavailability of polycyclic aromatic hydrocarbons (PAHs) in industrial and agricultural soils using chemical methods and a bioassay, and to study the relationships between the methods. This was conducted by comparing the quantities of PAHs extracted from two manufactured gas plant (MGP) soils and an agricultural soil with low level contamination by solid-phase micro-extraction (SPME) and Tenax-TA extraction with the quantities taken up by the earthworm (Eisenia fetida). In addition, a biodegradation experiment was conducted on one MGP soil (MGP-A) to clarify the relationship between PAH removal by biodegradation and the variation in PAH concentrations in soil pore water. Results demonstrated that the earthworm bioassay could not be used to examine PAH bioavailability in the tested MGP soils; which was the case even in the diluted MGP-A soils after biodegradation. However, the bioassay was successfully applied to the agricultural soil. These results suggest that earthworms can only be used for bioassays in soils with low toxicity. In general, rapidly desorbing concentrations extracted by Tenax-TA could predict PAH concentrations accumulated in earthworms (R=0.66), while SPME underestimated earthworm concentrations by a factor of 2.5. Both SPME and Tenax extraction can provide a useful tool to predict PAH bioavailability for earthworms, but Tenax-TA extraction was proven to be a more sensitive and precise method than SPME for the prediction of earthworm exposure in the agricultural soil.

“…For these reasons, chemical methods, e.g. non-exhaustive extractions and biomimetic methods, are increasingly being used as an alternative to bioassays [109,113,118,[121][122][123][124][125]. For example, chemical oxidation with persulphate [49,126] or hydrogen peroxide [56] has already been used to assess PAH availability in soils.…”
