“…This approach was used for evaluating the effect of compost amendment or soil fertilization with FYM on the PAH degradation, and thus, we did not enable aging of the pyrene or introduction of the compound within a tar oil matrix. The compost addition to soil facilitated complete pyrene degradation, and the results confirm the previous observation that compost addition enhances complete microbial degradation of PAH (Kästner and Mahro 1996;Loick et al 2009). Also, long-term organic fertilization resulted in almost complete pyrene degradation.…”

“…One historically developed and established remediation method is the addition of compost to contaminated soil or sediment. This method has been found to be cost-efficient and highly effective (Loick et al 2009;Semple et al 2001). Compost provides a wide variety of microorganisms, nutrients, extra carbon Electronic supplementary material The online version of this article (doi:10.1007/s00253-015-6822-8) contains supplementary material, which is available to authorized users.…”

“…Therefore, improving techniques with compost application for most efficient PAH bioremediation is still a field of research, since the mechanisms underlying the observed effect of compost addition, e.g., the introduction of microorganisms, nutrients, primary substrates, or all of them, are not yet clear. Supplementing contaminated soils with various types of compost material or other organic supplements, e.g., yard waste compost (Carlstrom and Tuovinen 2003;Kästner and Mahro 1996;Kästner et al 1995;Winquist et al 2014;Wu et al 2013), spent mushroom substrate (Cajthaml et al 2002;Lau et al 2003;Reid et al 2002;Šašek et al 2003), animal manure (Atagana 2004;Wong et al 2002;Yuan et al 2009), and sludges (Hamdi et al 2006(Hamdi et al , 2007Petersen et al 2003), has been successfully applied in order to remove PAH; a detailed summary is given elsewhere (Loick et al 2009). For optimal PAH removal, fully rotted compost has often been found to be much more effective than fresh compost (Haderlein et al 2006;Plaza et al 2009), and mature compost is considered to provide available nutrients with low sorption potential for high-molecular-weight PAH (AntizarLadislao et al 2005;Hafidi et al 2008).…”

Polycyclic aromatic hydrocarbons (PAH) are toxic pollutants widely distributed in the environment due to natural and anthropogenic processes. In order to mitigate tar oil contaminations with PAH, research on improving bioremediation approaches, which are sometimes inefficient, is needed. However, the knowledge on the fate of PAH-derived carbon and the microbial degraders in particular in compost-supplemented soils is still limited. Here we show the PAH carbon turnover mass balance in microcosms with soil-compost mixtures or in farmyard fertilized soil using [(13)C6]-pyrene as a model PAH. Complete pyrene degradation of 100 mg/kg of soil was observed in all supplemented microcosms within 3 to 5 months, and the residual (13)C was mainly found as carbon converted to microbial biomass. Long-term fertilization of soil with farmyard manure resulted in pyrene removal efficiency similar to compost addition, although with a much longer lag phase, higher mineralization, and lower carbon incorporation into the biomass. Organic amendments either as long-term manure fertilization or as compost amendment thus play a key role in increasing the PAH-degrading potential of the soil microbial community. Phospholipid fatty acid stable isotope probing (PLFA-SIP) was used to trace the carbon within the microbial population and the amount of biomass formed from pyrene degradation. The results demonstrate that complex microbial degrader consortia rather than the expected single key players are responsible for PAH degradation in organic-amended soil.

“…Among various remediation technologies, bioremediation using composting is considered one of the easiest and most cost-effective methods to treat PAHcontaminated soils (Antizar-Ladislao, Lopez-Real, and Beck 2004;Chen et al 2015;Loick et al 2009). Several studies showed significant degradation of PAHs using both conventional windrow composting systems (Amir et al 2005;Atagana 2004) and in-vessel composting systems (Antizar-Ladislao, Lopez-Real, and Beck 2006;Zhang et al 2011).…”

The present study was undertaken to investigate the removal of 16 polycyclic aromatic hydrocarbons (PAHs) listed as priority pollutants by the US Environmental Protection Agency (USEPA-PAHs) that are found in coal-contaminated soil during simulated in-vessel composting. Contaminated soil (S) was mixed with green waste (W) in the ratios of 3:1, 1:1, and 1:3 under neutral and acidic soil conditions in laboratory-scale composting reactors. The highest removal efficiency of total 16 USEPA-PAHs (71.88%) was observed in S:W ratio of 1:1 and neutral soil treatment with the removal rate constant of 0.0106 day ¡1 . Results found that the S:W ratio significantly influenced the removal of PAHs during composting but not the initial soil pH. The results of this research suggest that composting is a feasible and appropriate technology to remediate soil contaminated by coalnative PAH.

“…In general, HMW PAHs have very low aqueous solubilities, low vapor pressures, and high partition coefficients as compared to low molecular weight (LMW) PAHs (Olajire Abbas and Brack 2005). Information on the biodegradation of PAHs is well documented in the literature (Haritash and Kaushik 2009;Loick et al 2009). LMW PAHs containing two or three fused benzene rings are readily degraded under aerobic conditions in the presence of appropriate organisms (Silva et al 2009) while HMW PAHs degrade slowly and, in some situations, may be completely recalcitrant (Juhasz and Naidu 2000).…”

A solvent-water extraction method was proposed as an assessment tool to estimate the bioavailability of polycyclic aromatic hydrocarbons in coal-tar-contaminated soils. The approach taken was to measure the percent of polycyclic aromatic hydrocarbons extracted by a solvent-water mixture and comparing the results with the percent of polycyclic aromatic hydrocarbons degraded in a soil slurry reactor. Five soil samples from three former manufactured gas plant sites and a coal-tar disposal site which were operated between 1880 and 1947, and 1945 and 1950, respectively, in Iowa, USA were used in this study. Extraction experiments were conducted using acetone-water or ethanol-water mixtures with solvent volume fractions ranging from 1.0 to 0.4 (v/v). The percent of polycyclic aromatic hydrocarbons extracted from the various soils decreased as the volume fraction of the solvent in the solvent-water mixture was reduced. An acetone-water mixture of 0.6 was found to be appropriate in correlating the percent of polycyclic aromatic hydrocarbons degraded to the percent of polycyclic aromatic hydrocarbons extracted. For the first correlation, the percent extracted and the percent biodegraded were modified by using the molecular weights and log K ow of polycyclic aromatic hydrocarbons, respectively. For the second correlation, the equation relating the percent extracted and the percent biodegraded was modified using soil properties such as organic carbon content and percent of clay and silt. Although the experiments were conducted for a limited number of soils, the extraction method appeared to be a good starting point in estimating the bioavailability of polycyclic aromatic hydrocarbons in coal-tar-contaminated soils.
