Earthworms can 'biotransform' or 'biodegrade' chemical contaminants, rendering them harmless in their bodies, and can bioaccumulate them in their tissues. They 'absorb' the dissolved chemicals through their moist 'body wall' due to the interstitial water and also ingest by 'mouth' while soil passes through the gut. Since the advent of the nanotechnology era, the environmental sink has been cont...

This work sets out to investigate biological responses of Eisenia fetida to Cd, based on the bioavailable rather than total concentration of Cd, in soils. E. fetida was cultured for 14d in three selected Chinese soils amended with 0.1-40mgkg-1 Cd. Potentially bioavailable concentrations of Cd were measured in soil solution, in extractions using CaCl2 and HAc solutions, and using the technique o...

in this study, the earthworms of tehran province were investigated. specimens were collected from wet soil in 48 stations during 2011 and 2012. during the course of the study, eight earthworm species were identified, including: aporrectodea caliginosa (savigny, 1826), ap. rosea (savigny, 1826), dendrobaena veneta (rosa, 1886), dendrodrilus rubidus (savigny, 1826), eisenia fetida (savigny, 1826)...

in the process of vermicomposting, the earthworms eisenia fetida have been exposed to various metals with different concentrations to study the effects on worms’ bioaccumulation. the study was carried within 14 days of exposure. five different chemical compounds in various concentrations were added as mixture solutions to the experimental containers. metals concentrations were measured in earth...

This paper reports the vermicomposting of food industry sludges (FIS) mixed with different organic wastes employing Eisenia fetida. A total of 10 vermicomposting units containing different wastes combinations were established. After 15 weeks significant increase in total nitrogen (N(total)) (60-214%), total available phosphorous (P(avail)) (35.8-69.6%), total sodium (Na(total)) (39-95%), and to...
