Snails were collected in autumn and spring, when they are most active. RESULTS: In general, TE in the soft tissues(More)
We evaluate the mid-term effects of two amendments and the establishment of R. officinalis on chemical and biochemical properties in a trace element contaminated soil by a mine spill and the possible use of this plant for stabilization purposes. The experiment was carried out using containers filled with trace element polluted soil, where four treatments(More)
