“…It is therefore impossible to evaluate the toxicity of soil pollutants based solely on the oil and grease content. Ecotoxicity bioassays should therefore be used as supplementary tools for monitoring treatment effects [11]. In our study P. phosphoreum T3 was used to test the biotoxicity of the oily sludge before and after bioremediation.…”

a b s t r a c tField-scale bioremediation of oily sludge in prepared beds was studied at Shengli oilfield in northern China. The influence of manure, coarse sand, sawdust, a specialized microbial preparation and greenhouse conditions on the efficiency of removal of oil and grease was evaluated. After bioremediation for 230 d, oil and grease content fell by 32-42 g kg −1 dry sludge in treated plots, indicating removal of 27-46% compared with only 15% in the control plot. Addition of manure, coarse sand, sawdust and greenhouse conditions significantly (p < 0.05) increased the amount removed. Moreover, the physico-chemical properties of the sludge in all treated plots improved significantly after bioremediation. Microbial biomass in sludge and community-level physiological profiling examined using BIOLOG microplates was also studied. Total petroleum hydrocarbon degraders and polycyclic aromatic hydrocarbon degraders increased in all treated oily sludge. The activity of sludge microbial communities increased markedly in the treated plots compared with the control. Canonical correspondence analysis showed that differences in substrate utilization patterns were highly correlated (p < 0.05) with sludge hydrolyzable N and oil and grease content. The biological toxicity of the oily sludge was lower following bioremediation in most of the treated plots as evaluated using Photobacterium phosphoreum T3.

“…DCM and dimethylsulfoxide (DMSO) were used to extract the sludge according to the method of Płaza et al [11]. The biological toxicity of the DCM/DMSO extracts and DMSO (control) were tested based on the measurement of reduction in light emission by Photobacterium phosphoreum T3 under toxic stress.…”

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.

“…For successful implementation of such bioassays, reactions of the organisms towards toxic compounds and the type of toxic compounds causing the reactions have to be clearly defined and test conditions to be standardised. Following sufficient assessment of the standardised tests proving their practicability and reliability, their usage might be approved on national and international level (Keddy et al 1995, Cook et al 2002, Braunbeck et al 2005, Plaza et al 2005. It is important to note that no universal bioassay is available for detection of all types of pollution, neither, there is a biological test that works under all circumstances for a given pollutant.…”
