Eisenia fetida is very easily identified by its striped appearance of alternating broad, dark red-brown bands and narrower, pale pink or yellowish bands.Its saddle (the clitellum) is generally the same dark red-brown as the rest of its body. Therefore, increasing efforts have been made to deal with environmental pollution issues in the PRD region. Guangdong Institute of Eco-environmental and Soil Sciences, Removal of persistent DDT residues from soils by earthworms: A mechanistic study, Enhancement effect of earthworm ( Eisenia fetida ) on acetochlor biodegradation in soil and possible mechanisms, Bioremediation of co-contaminated soil with heavy metals and pesticides: Influence factors, mechanisms and evaluation methods, Assessment of earthworm activity on Cu, Cd, Pb and Zn bioavailability in contaminated soils using biota to soil accumulation factor and DTPA extraction, Impacts of earthworm species on soil acidification, Al fractions, and base cation release in a subtropical soil from China, Insights into the mechanisms underlying the remediation potential of earthworms in contaminated soil: A critical review of research progress and prospects, Vermiremediation of Biomixtures from Biobed Systems Contaminated with Pesticides, How persistent are POPs in remote areas? The latter part of this review considers organic compounds in the following order: agrochemicals, petroleum and crude oil hydrocarbons, PAHs and PCBs. For pyrene, the results surprisingly showed peak-shape accumulation curves despite long aging. Spent lubricant oil-contaminated soil toxicity to Eisenia andrei before and after bioremediation. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The levels of PCBs found in the composts were 32 to 440 ng sum PCB/g dw and 23 to 290 ng/g ww in the worms. In the oil-contaminated soil, respiration and concentration of microbial biomass was significantly enhanced by earthworm amendment, and TPH concentrations decreased significantly. Ecotoxicol Environ Saf. *: P # 0.05, **: P # 0.01, and ***: P # 0.001. The concentrations of the chlordanes were 0.01 to 0.2 ng/g dry weight (dw) in compost and 0.03 to 0.06 ng/g wet weight (ww) in the worms. Results showed no decrease in condition in the shooting site earthworms with increasing exposure time or concentration. Therefore, our study focused on the uptake kinetics of four hydrophobic organic compounds (pyrene, lindane, p,p'-DDT and PCB 153) in two laboratory-contaminated natural soils with different soil properties (e.g. This study demonstrated the important role of DIRB and iron oxide on DDT and DDD transformation under anaerobic iron-reducing environments. In this study, earthworm (Eisenia fetida) alone or combined with EDTA or bean … In this study, the common composting earthworm Eisenia fetida was tested for utility to improve remediation of oil-impacted soil. 2013). A conceptual model for transformation of environmentally widespread persistent organic pollutants (DDT, HCH, PCBs and benz(a)pyrene) in the air-plant-soil system was developed. • Results: – earthworms will survive in bioremediated soil with high residual TPH concentrations; – … Specimens of the earthworms Lumbricus terrestris L. and L. rubellus Hoffmeister from an uncontaminated site rapidly deteriorated in condition when kept in spoil rich in metal contaminants and arsenic. POPs in the environment might decline rapidly due to a reduction in source input and significant degradation as indicated by our study. USA.gov. Earthworm cast was the degradation hotpot in drilosphere and exhibited better anaerobic degradation capacity in microcosm experiments.
