Effects of field metal-contaminated soils submitted to phytostabilisation and fly ash-aided phytostabilisation on the avoidance behaviour of the earthworm Eisenia fetida

The impact of cow dung augmentation on soil restoration and bio-accumulation of metals (Lead and Cadmium) in Pheretima posthuma (Annelida: Clitellata)

“…The use of cow dung as an additional dose to observe its effect on bioaccumulations/ bioassimilations of available heavy metals (Zn, Pb and Cd) in earthworm tissues (L. violaceus) was generally low and time dependent (Dada et al, 2016). These variations in Cow dung augmentation impact on soil restoration and bio-accumulation of metals results might be due to different species (Nannoni et al, 2014), metal bioavailable concentrations in substrates (Liu et al, 2017) and metal physiological tolerance or ecological habitat (Demuynck et al, 2014). The positive effect of cow dung on bio-assimilation of heavy metals (Pb-Cd) from environment and aqueous solution was due to its absorbent property with metals ions (Ojedokun and Bello, 2016;Vijver et al, 2003).…”

Sustainability of an in situ aided phytostabilisation on highly contaminated soils using fly ashes: Effects on the vertical distribution of physicochemical parameters and trace elements

“…This experimentation has already been used to assess the effects of aided phytostabilisation using fly ashes (FA), woody plants and herbaceous plants on the soil's physicochemical parameters, the vegetation and the soil mesofauna (Demuynck et al, 2014;Grumiaux et al, 2010;Lopareva-Pohu et al, 2011a, 2011bPourrut et al, 2011). In 8 years, soil has undergone a structural and chemical transformation through the formation of organic layers, root system growth and mesofauna colonisation under variable climatic conditions.…”
