“…As for the aged Red earth and Aquic-fluvo soil, up to 91.9 ± 8.5 and 45.5 ± 6.7% of the initial pyrene dissipated in the presence of earthworms, while only 36.5 ± 9.3 and 20.5 ± 5.3% of the initial pyrene was removed in the worm−free treatments. Similar results have been reported on the earthworm-assisted removal of PAHs in previous literature (Contreras-Ramos et al, 2008;Eijsackers et al, 2001;Alvarez-Bernal et al, 2006). However, the mechanism for the enhanced PAH removal is so far still unclear.…”

Microbial degradation of pyrene was studied in soils in the presence and absence of earthworms (Eisenia foetida) to demonstrate an integrated innovative strategy for bioremediation of sites lightly polluted by polycyclic aromatic hydrocarbons. Desorption of pyrene and soil microbial respiration were measured to elucidate the mechanism of enhanced microbial degradation. The results showed that both soil properties and contact time could influence pyrene biodegradation. The introduction of E. foetida enhanced pyrene removal significantly both in freshly spiked and aged soils. The percentage pyrene removal in the presence of E. foetida was 45.5-91.0% after 14 d of incubation, which were 2.1 to 2.8 times greater than those without the worms. The enhanced pyrene removal is attributed to both enhanced microbial degradation and uptake by the worms. Microbial degradation of pyrene increased by 1.2 to 1.6 times in the presence of the worms. Overall, the introduction of live worms could improve both pyrene bioavailability and microbial activity, which leads to enhanced microbial degradation of pyrene.

“…Song et al (2002) recovered 93% of anthracene, but only 74% of phenanthrene from soil with 98% sand using the same technique while Alvarez-Bernal et al (2006) reported a 96% recovery for anthracene and 95% for phenanthrene from the same Acolman soil. Differences in recovery are affected by the extraction method, the nature and concentration of the contaminant and the soil characteristics (Van Hamme et al, 2003;Stokes et al, 2006).…”

“…Diuron has an affinity to form hydrophilic groups of vermicompost, which restrict the efficient distribution of diuron in soils. Vermicompost application removed PAHs such as phenanthrene, anthracene, and benzo(a)pyrene from soils (Alvarez‐Bernal, Garcıa‐Diaz, Contreras‐Ramos, & Dendooven, ). However, vermicompost application removed PAHs in lesser amounts when compared with the results of the direct application of earthworms (e.g., Esinea fetida and biosolids) (Contreras‐Ramos, Alvarez‐ Bernal, & Dendooven, ).…”

Improperly managed organic waste constitutes a serious environment threat across the globe. This has led to a worldwide struggle to strike a balance between the rapid generation of such wastes and protection of the environment. With the unique advantages of lower operational and maintenance costs compared with other waste management technologies, the use of vermicomposting to manage organic wastes has been increasing rapidly in recent years. Still, some factors (e.g., characteristics of substrate composition before and after treatment) are in need of additional, specific studies so that researchers can better understand the metabolism involved in the process. Vermicomposting provides employment opportunities as it protects the environment, augmenting crop productivity when it is used as a fertilizer supplement and helping to maintain ecological balance. Thus, vermicompost plays an important role in the circular economy. This article provides an overview of the research activities that have been conducted on the use of vermicomposts to remove pollutants from the soil, in wastewater treatment, and in organic waste recycling throughout the world. Circular economic assessment has revealed that vermicomposting technology is usually feasible except in certain cases. Most other methods of waste disposal lead to soil deterioration, toxic effects, and increased pollution affecting land, air, water, and living beings, in addition to the sometimes considerable expense of their implementation. Thus, an eco‐friendly method that removes waste in one step is needed. Determining the long‐term performance and sustainable operation of vermicomposting systems still poses a challenge, however, as treatment performance is affected by design parameters, operational conditions, and environmental factors. This article summarizes the factors influencing pollutant removal through the vermicomposting process. Finally, this article highlights additional research that should be conducted on these issues to improve the performance of vermicomposting.
