La mesure de SO4-- en excès. Oden (1976), Henriksen (1979), Dickson (1975), Watt et coll. (1979) proposent l'utilisation des valeurs de SO4-- en excès dans les eaux de surface comme un bon indicateur de l'acidification des lacs. La contamination des eaux de surface par H2SO4 (pluies acides) amène un remplacement du HCO3- par les SO4-- et l'apparition de CaSO4 dans la décharge des eaux au lieu de CaCO3. Le SO4-- en excès n'est pas corrélé par le pH, en raison de la forte relation du SO4-- versus l'activité des microorganismes (cycle de SO4 - H2S) et l'oxygène. 3, record 1, French, - en%20exc%C3%A8s
