“…Soil properties including texture, organic matter content, pH, particle size, cation exchange capacity and structure have been shown to affect not only plant growth and microbial colonization [19][20][21], but also the degradation of organic contaminants [22][23][24]. Moreover, the bioavailability of hydrocarbons may be influenced by soil properties [25][26][27].…”

“…The first type of soil sample (the Latomäki soil sample) was obtained from a depth of 40 cm at Lumijoki in the autumn of 2005. This soil was used recently also in our previous studies (Kaakinen et al 2007). The other soil type (the Peuraneva soil sample) was sampled at a few centimetre depth at Alavieska in the autumn of 2004.…”

“…Our observation of the biodegradability of light fuel oils as being clearly better in mineral-rich soil conditions are in accordance with our earlier study on biodegradation, in which the optimizing of mineral concentrations and the pH of soil improved the biodegradation of rapeseed oil-based chain oil and lubricating oil significantly, increasing biodegradation degrees from 7.4% to 75.8% and from 5.9% to 51.9%, respectively. (Kaakinen et al 2007.) Furthermore, it became apparent that biodegradation was still in progress when samples were incubated for 30 days.…”

“…It was also assumed that certain wear metals (such as zinc and nickel) in the oils can have an effect on the biodegradation. The BOD OxiTop® method has been intensively used in our biodegradability studies of oils, because it has proven to be a useful and accurate method of analysis (Vähäoja et al 2005a, b;Kaakinen et al 2007).…”

In this biological oxygen demand (BOD) study, the manometric respirometric BOD OxiTop® method was used to monitor the biodegradation of two summer grade (SFO 1 and 2) and two winter grade light fuel oils (WFO 1 and 2) in OECD 301 F conditions, in groundwater, and in two different Finnish forest soils (mineral-poor and mineral-rich). The biodegradation measurements in the OECD 301 F conditions were carried out in two nutrient solutions for 28 days. In both solutions WFO 1 reached the highest biodegradation degree, 32% in the solution OECD 301 F, and 70% in a solution containing additional ammonium chloride. In groundwater conditions all the biodegradation degrees of fuel oils remained below 2% within the 28-day period.SFO 1 reached the highest 30 day biodegradability (4%) in mineral-poor soil, 18% in mineral-rich soil. In a 189-day measurement in a mineral-rich soil, the biodegradation degree for the SFO 1 was 94%. The manometric respirometric method proved to be a very suitable and practicable measurement method for the purpose of biodegradation studies of highly volatile light fuel oils, because in this method samples are treated to a lesser degree than in conventional methods, and dilutions are not needed. Results also indicated a considerable effect of conditions on the biodegradability in both water and soil environments. The results of these biodegradation studies could be used when planning in situ treatment methods based on natural biodegradation. In situ treatment methods are eco-efficient, and are especially suitable for sparsely populated sites.

Effect of lead, cadmium, and mercury co‐contaminants on biodegradation in PAH‐polluted soils

Contamination of land by persistent organic pollutants has significant implications for human health and for future development potential. Bioremediation is an effective method for reducing the concentrations of such contaminants to below harmful levels, but the presence of co‐contaminants may hinder this process. Here, we present the results of a 40‐week microcosm study in which the biodegradation of 16 United States Environmental Protection Agency (USEPA) polycyclic aromatic hydrocarbons (PAHs; total: 2,166 mg kg−1) was followed in the presence of 3 different concentrations of cadmium (up to 620 mg kg−1) and lead (up to 782 mg kg−1) in a high organic matter soil. In the absence of metal treatment, 82% of PAHs were removed during the study period. Lead exerts a greater negative effect on total PAH removal than cadmium at low concentrations (approximately 100 mg kg−1) whilst cadmium exerts the greatest effect at higher concentrations (up to −27.7% reduction). Mercury, intended as the abiotic control (approximately 1,150 mg kg−1), exerts the greatest effect overall (−37%). Principal Component Analysis showed that PAH degradation was strongly associated with soil respiration rate, biomass content, and Ecoplate Average Well Colour Development. During the initial phase of the experiment, reduced microbial diversity was associated with increased PAH removal, consistent with literature observations for other organic contaminants, though this association was reversed after Week 12. Degradation of higher molecular weight PAHs showed the greatest sensitivity to the health of the microbial community. The effect of metal treatments on biotic parameters in microcosms without PAH amendment is also presented.
