Abstract: Heavy metal contamination is an important environmental problem which couldaffect the durability and fertility of soils. For the enhancement of soil properties in mine soils, many technologies can be used. In this study, we have assessed the efficacity of vermeremdiation (The use of earthworms for remediation). In this context, this study investigate the effect of earthworms Eisneia andrei on physicochmical properties of soils. For this purpose, six polymetllaic contaminated soils from Jebel Ressass mine (ranged from the most contamianted one A to control one F) were incubated during 14, 28 & 60 days in presence and absence of earthworms Eisenia Andrei. Organic matter, available phosphorous, potassium and magnesium and active limestone were assessed in each incubation point. Our results schowed that earthworms increased organic matter content especially for soil A.
