In this work we used field- and laboratory-grown S. palustre moss treated by EDTA and devitalized by oven drying, to elaborate a consistent procedure of metal and proton adsorption on moss surfaces and a biomonitoring protocol using cloned moss. Devitalization and EDTA treatments did not produce any measurable difference in terms of H and Pb adsorption capacities of moss surfaces. Therefore, in view of the use of S. palustre clone for biomonitoring purposes, we recommend devitalization as unique treatment to perform with the aim to preserve the biomaterial before and after its exposure in bags.
