Abstract
Vaccinium sp., Rhododendron ferrugineum and mosses are the dominant plant groups present on the moraine soils of Barme I, Barme II and Pierrier in the Arpette valley. The amount of o-diphenols (ODP) available in plants and susceptible to be released each year to the soil surface was determined by HPLC. The quantity of caffeic acid, catechol and protocatechuic acid present in the leaves ranged between 25 and 250 mg/m 2 . The impact caused by Cu pollution on this type of ecosystems was studied by a chemical speciation approach. Potentiometric alkaline titrations were carried out on synthetic phenol solutions containing increasing Cu concentrations. Cu complexation increased with an increasing pH, but in order to have all the Cu in the complexed form a minimum ratio of (4:1) ODP-Cu in the solution was necessary.
