  abstract = {{T}hallium concentration reached up to 534 mu g {L}-1 in the {R}eigous acid mine drainage downstream from the abandoned {P}b-{Z}n {C}arnoules mine ({S}outhern {F}rance). {I}t decreased to 5.44 mu g {L}-1 in the {A}mous {R}iver into which the {R}eigous creek flows. {TI}({I}) predominated (> 98% of total dissolved {T}l) over {T}l({III}), mainly in the form of {T}l+. {S}mall amounts of {T}l({III}) evidenced in {R}eigous {C}reek might be in the form of aqueous {T}l{C}l2+. {T}he range of dissolved to particulate distribution coefficients log {K}-d = 2.5 {L} kg(-1) to 4.6 {L} kg(-1) indicated low affinity of {T}l for particles, mainly ferrihydrite, formed in the {AMD}-impacted watershed. {T}he low retention of {T}l+ on ferrihydrite was demonstrated in sorption experiments, the best fit between experimental and modeled data being achieved for surface complexation constants log {K}-ads = -2.67 for strong sites and log {K}-ads = -3.76 for weak sites. {T}his new set of constants allowed reasonable prediction of the concentrations of aqueous and particulate {T}l resulting from the mixing of water from {R}eigous {C}reek and the {A}mous {R}iver water during laboratory experiments, together with those measured in the {A}mous {R}iver field study.},
