Metal induced non-metallothionein protein in earthworm: A new pathway for cadmium detoxification in chloragogenous tissue

Ecological adaptation of earthworms for coping with plant polyphenols, heavy metals, and microplastics in the soil: A review

“…M. californica , A. hupeiensis , A. asacceus accumulated Zn (2.86–6.46 m mol kg −1 ), Cu (0.55–1.62 m mol-kg −1 ), and Cd (0.27–0.60 m mol kg −1 ), respectively [ 61 ]. Through the development of MTs and/or other induced-proteins in their stomach, earthworms can detoxify by reducing the bioavailability of HMs [ 62 , 63 ]. Earthworms are also known to alter the distribution of Sb fractions, which lowers Sb bioavailability [ 64 , 65 ].…”

Assessment of bioremediation potential of metal contaminated soils (Cu, Cd, Pb and Zn) by earthworms from their tolerance, accumulation and impact on metal activation and soil quality: A case study in South China

“…As Cd is highly mobile (Nannoni et al, 2011 ) and easily combines with metallothionein (MT) and non-metallothionein proteins (ie. MIP) in earthworm tissue (Morgan et al, 1989;Hussain et al, 2021), Cd accumulation in earthworm should not be overlooked. Metal BSAFs ranked as Cd > Zn > Cu and Pb (Tab.…”

Divergent Responses of Earthworms (Eisenia Foetida) in Sandy Loam and Clay Soils to Cerium Dioxide Nanoparticles

“…4a. MT is a metal-binding peptide with a molecular weight of 6-7 kDa that can chelate various metals ions, such as Zn 2+ , Cu 2+ , Cd 2+ , and Cr 3+ , through mercaptide linkages and transport the bound metals to chloragogenous tissues to complete the detoxi cation process (Blindauer &Leszczyszyn 2010, Homa et al 2016, Hussain et al 2021. The Ce ions that accumulate in the circular and longitudinal muscles of earthworms cause stress, which can trigger MT synthesis to reduce damage to the epidermal and midgut cells (A et al 2020).…”
