“…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.

“…For this reason it is important to control their concentrations (Busetti et al 2006). One way to control the pollutant concentration in these wastes is through chemical analysis but, regardless of their accuracy and sensitivity, chemical analyses do not provide direct information concerning the biological effects of toxic compounds (Hamdi et al 2006;Stasta et al 2006). Consequently, biological monitoring, or toxicological assessment has, in this case, a major advantage over chemical analysis (Cook et al 2002).…”

Phytotoxic effects of sewage sludge extracts on the germination of three plant species

et al. 2008

In order to evaluate the ability of three types of extracts to explain the ecotoxicological risk of treated municipal sewage sludges, the OECD 208A germination test was applied using three plants (Lolium perenne L., Brassica rapa L., and Trifolium pratense L.). Three equivalent batches of sludge, remained as dewatered sludge, composted with plant remains and thermally dried, from an anaerobic waste water treatment plant were separated. Samples from these three batches were extracted in water, methanol, and dichloromethane. Plant bioassays were performed and the Germination Index (GI) for the three plants was evaluated once after a period of 10 days. Germination in extracts was always lower than the respective controls. The germination in composted sludge (GI 40.9-86.2) was higher than the dewatered (GI 2.9-45.8), or thermally dried sludges (GI 24.6-64.4). A comparison of the germination between types of extracts showed differences for dewatered sludge with the three plants, where the water and methanol extracts had significantly lower germination than the dichloromethane extract. A higher half maximal effective concentration (EC50) in composted extracts was established, mainly in the water extract (EC50 431-490 g kg(-1)). On the contrary, the germination was strongly inhibited in the water extract of the dewatered sludge (EC50 14 g kg(-1)). The germination was positively correlated with the degree of organic matter stability of the parent sludge, and an inverse correlation was detected for total nitrogen, hydrolysable nitrogen and ammonium content. It is concluded that the phytotoxic effect of the water extract is more closely related to hydrophilic substances rather than lipophilic ones, and care must be taken with dewatered sludge application, especially with their aqueous eluates. Results obtained in this work show the suitability of the use of sludge extracts in ecotoxic assays and emphasize the relevance of sewage sludge stabilization by post-treatment processes.

“…The potential phytotoxicity of ionic liquids not only depends on the quantity and quality of soil colloids, but it can also be determined by the amount of a ionic liquid in the substrate and the genetic features of species or varieties [8,15,21,37,39]. At present, phytotoxicity tests are widely used in the biomonitoring of the quality of agriculturally utilized sewage sludges [46][47][48][49][50][51][52][53], residues of PAHs and pesticides [50,[56][57][58][59], or the heavy metal contents of soil [58].…”

Ionic liquids have attracted considerable interest in various areas as new, non-volatile and nonflammable organic solvents, catalysts, reaction additives, ligands, drugs and other dedicated materials etc. Their general use, sometimes in bulky quantities, requires determination of their potential ecotoxicity on selected organisms. In the present work, influence of triphenylmethylphosphonium iodide (1) and triphenylhexadecylphosphonium iodide (2), introduced to soil, on germination and early stages of growth and development of superior plants was investigated using the plant growth test based on the OECD/OCDE 208/2006. In this test, the seeds of selected species, i.e. land superior plants -spring barley (Hordeum vulgare) and common radish (Raphanus sativus L. subvar. radicula Pers.) were planted in pots containing soil to which a test chemical compound had been added and in pots with control soil. To evaluate the phytotoxicity of ionic liquids 1 and 2 germination and weight (dry and fresh) of control plant seedlings were determined and compared with the germination and weight (dry and fresh) of the seedlings of plants grown in the soil watered with appropriate amounts of the test chemicals. The visual assessment of any types of damage to the test species, such as growth inhibition, chlorosis and necrosis, was also carried out and documented by digital photographs. Based on the obtained results, magnitudes of the LOEC -the lowest concentration causing observable effects in the form of reduction in growth and germination compared with the control and the NOEC -the highest concentration not causing observable, toxic effects -were also determined.
