“…3). Organically bound A1 is the major form of A1 in peat (Wieder et al 1986), and it seems likely that aqueous concentrations of A1 are controlled by partitioning between the solid-phase organically-bound A1 and solution (Cronan et al 1986;Clair & Freedman 1986;Turner et al 1985;Dawson et al 1978;Ugolini et al 1977). The model of Cronan et al (1986) assumes that aqueous Al+3 concentrations are in equilibrium with A1 on organic ion exchange sites.…”

“…Bogs (i.e., peatlands that receive no ground water or runoff from mineral soils) typically have acidic, nutrient-poor, highly organic soils. Bog waters and streams receiving bog drainage exhibit low pH (3-9, high concentrations of dissolved organic carbon ([DOC]'= 5-55 mg L-I ), and frequently high concentrations of A1 (3-74 pmol L-I ;Verry 1975;Schurr 1983;Urban et al 1987a;Clair & Freedman 1986). Understanding the controls on A1 in peatland waters is important for evaluating the effects of acidic precipitation on peatlands and surface waters (Gorham et al, 1984), the utility of peatlands for removal of metals derived from industrial and mining effluents or highways (Eger et al 1981;Coker & DiLabio 1979;Wieder et al 1988), the effects of natural organic ligands on metal ion reactivity and dissolution (e.g., Waite et al 1988), and the autecology of bog plant species (e.g., Sparling 1967).…”

“…Peat accumulates due to water-logging, anaerobic conditions and thus slow rates of decomposition. Hydrologie, thermal, and nutrient regimes are the controlling factors of decomposition in wetlands (Moore 1988 Day et al 1977;Mulholland and Kuenzler 1979;McKnight et al 1985;Clair and Freedman 1986;Collier et al 1989;Urban et al 1989: Eckhardt andMoore 1990 …”
