Modulation of flyash-induced genotoxicity in Vicia faba by vermicomposting

Reduction of bioavailability of heavy metals during vermicomposting of phumdi biomass of Loktak Lake (India) using Eisenia fetida

“…Reduction of the leachable concentration of metals during vermicomposting of phumdi biomass might be due to accumulation of metals in the earthworms. Similar results were reported by Jain et al (2004). The present study exposed that the leachability of metals decreases with vermicomposting time and that might be due to increase in pH and complexity of metal humic substances.…”

“…The DTPA extractable concentration of Ni and Cd was not detected during the vermicomposting of phumdi biomass. The highly toxic form Cr (VI) is converted to nontoxic form Cr (III) through metabolic process in mitochondrial and cytoplasmic fractions has also been demonstrated in E. fetida (Jain et al, 2004). The reduction of DTPA extractable metals during vermicomposting is also reported by other researchers (Suthar, 2009, Singh andKalamdhad, 2013d).…”

Feasibility of Eudrilus eugeniae and Perionyx excavatus in vermicomposting of water hyacinth

“…Earthworms may accumulate non-essential toxic heavy metals when they are exposed to heavy metal contaminated soils (Li et al, 2010). They can reduce possible toxic effects of heavy metals through mitochondrial and cytoplasmic fractions (Jain et al, 2004). Vermicomposting is a decomposition process involving interactions between earthworms and microorganisms and it is an economical, viable and sustainable option for water hyacinth management.…”

Treatment technologies for urban solid biowaste to create value products: a review with focus on low- and middle-income settings

“…Recent research has further studied the potential of using vermicomposting for different waste types, such as food industry waste (Garg et al 2012), and also for treatment of industrial and polluted waste. Vermicomposting has shown to reduce toxic metal content and break down of chemicals to non-toxic forms (Jain et al 2004). Used in sludge management, Shahmansouri et al (2005) show that heavy metals in organic matter are taken up by the skin and intestine of earthworms during ingestion resulting in lower concentrations in the sludge.…”
