“…Recently, electrokinetic remediation, enzyme-mediated bioremediation, multi-process phytoremediation and vermiremediation have been employed in the treatment of PAHs contaminated soils (Kuppusamy et al, 2016d,e). Notably, existing research on the application of vermiremediation (Ekperusi and Aigbodion, 2015) to treat PAHs contaminated soils is very limited. There are wider avenues to investigate the use of these new remedial approaches in conjunction with the established physical, chemical and/or biological treatments to achieve maximum PAH removal efficiency.…”

For more than a decade, the primary focus of environmental experts has been to adopt riskbased management approaches to cleanup PAH polluted sites that pose potentially destructive ecological consequences. This focus had led to the development of several physical, chemical, thermal and biological technologies that are widely implementable. Established remedial options available for treating PAH contaminated soils are incineration, thermal conduction, solvent extraction/soil washing, chemical oxidation, bioaugmentation, biostimulation, phytoremediation, composting/biopiles and bioreactors. Integrating physico-chemical and biological technologies is also widely practiced for better cleanup of PAH contaminated soils. Electrokinetic remediation, vermiremediation and biocatalyst assisted remediation are still at the development stage. Though several treatment methods to remediate PAH polluted soils 3 currently exist, a comprehensive overview of all the available remediation technologies to date is necessary so that the right technology for field-level success is chosen. The objective of this review is to provide a critical overview in this respect, focusing only on the treatment options available for field soils and ignoring the spiked ones. The authors also propose the development of novel multifunctional green and sustainable systems like mixed cell culture system, biosurfactant flushing, transgenic approaches and nanoremediation in order to overcome the existing soil-contaminant-and microbial-associated technological limitations in tackling high molecular weight PAHs. The ultimate objective is to ensure the successful remediation of long-term PAH contaminated soils.

“…Electronic industrial sludge consists of metals, such as aluminum, nickel and lead. In this report, metal compounds elimination from electronic factory waste sludge, during the vermicompost process, was confirmed (8,29) 42. One research, titled "Heavy metals remediation from urban wastes using three species using of earthworms (Eudrilus eugeniae, Eisenia fetida and Perionyx excavates)", showed that elimination of cadmium, lead, zinc and copper during the vermicompost process by using Eudrilus eugeniae, Eisenia fetida and Perionyx excavates in three types of wastes (MSW, MW and FW) in 60 days in Eudrilus eugeniae was more than other species.…”

“…According to their health disorders, it is necessary to manage this hazardous compounds (30). The heavy metals accumulated in earthworms tissues are analyzed in terms of concentration factors, such as the bioconcentration factors (BCFs) and the bioaccumulation factors (BAFs) with the assumption that the organisms have achieved chemical equilibrium with respect to a particular media or route of exposure (8,30).…”

Background: During the paint spraying process in the automotive industry, a variety of wastes, including a large amount of paint sludge is produced, which contains a variety of hazardous substances, such as BTEX and heavy metals. The aim of the present study was vermicomposting of paint sludge with sewage sludge and Eisenia fetida as earthworm spices for reduction of heavy metals. Objectives: Vermicomposting process employing earthworms is increasingly being used for conversion of both sewage and some industrial wastes to reduced heavy metals and volatile solid content in bulk of solid wastes. Therefore, in this study, feasibility of chromium removal from paint sludge by using Eisenia fetida worms was investigated. Methods: In this study, the quantitative and qualitative characteristics of paint and biological sewage sludge waste were determined in terms of Cr +6 , moisture content, nitrogen and carbon, C/N ratio, pH and temperature. Then the paint sludge was mixed in various proportions with the thickening biological sewage sludge of Saipa's sewage treatment plant. The decomposition time for the vermicompost samples for each run was 90 days. In order to analyze various parameters, including Cr +6 and volatile solids reduction, sampling from each pilot was performed on 1, 15, 30, 50, 70 and 90 days. The Cr +6 measurements were performed using the AASM method. The paint sludge and sewage sludge were mixed in different ratios. After the mixing, 500 adult Eisenia fetida earthworms were introduced to each box. Results: The results showed that the optimum removal rate for Cr +6 was found in the mixing ratio of 6 kg of biological sludge with 600 g of paint sludge and in this ratio, the amount of Cr +6 concentration fell from 6 mg/kg to less than 0.2 mg/kg in 90 days. In addition, in the same ratio of sludge mixing, the C/N ratio ranged from about 27 on the first day to 14.3 on day 90 and the pH decreased from 7.8 on the first day to 7.3 on the 90 th day. Volatile solids decreased from 80.4% on the first day to 37% on the 90 th day. Conclusions: Vermicomposting is a good alternative for treating paint sludge with biological sludge, and is advantageous for reduction of pollutants purposes. Research was carried out on bioavailability of heavy metals such as Cr +6 during vermicomposting for 90 days using Eisenia fetida earthworms. Finally, the results showed that, Eisenia fetida could eliminate Cr +6 in low levels.

“…Earthworms play essential part in enhancing soil ecology by increasing the levels of available nutrients and microflora (Yadav et al, 2017b) because of their tunneling movement. Previous studies have stamped worms' utility in bioremediation as worms have the ability to uptake heavy metals from contaminated soil (Romero-Freire et al, 2015;Ekperusi and Aigbodion, 2015;Verma et al, 2016 andWang et al, 2016). Accordingly, the role of worms' as soil engineers can't be ignored.…”

The present study of 28 days was carried out to assess the effect of arsenic and chromium on biomass gain and reproduction parameters (cocoon and hatchling production) of E. eugeniae. The worms were cultured in substrate having different concentrations of arsenic and chromium alongwith control in triplicates. Dose and time dependent decreased in number of adults, cocoon production and hatchling emergence and reduction in growth was observed. In worms exposed to Cr (0.1 ppm), reduction in population (24.66%), body weight (2.44%), cocoon production (47.14%) and hatchling emergence (39.99%) was observed. While As (0.1 ppm) exposure resulted in reduction of adult population (10.66%), body weight (0.24%), cocoon production (37.05%) and hatchling emergence (28.53%) was observed. Cocoon production was observed to be the most sensitive parameter for heavy metal exposure in all treatments. Chromium was observed to be more detrimental to earthworms when compared with arsenic.
