A model has been developed that relates the cation denudation rate (CDR) of a watershed (the rate that cations derived from chemical weathering are carried off by runoff), the atmospheric load of excess SO4--, and the pH of the river. 2, record 1, English, - cation%20denudation%20rate

En étudiant les taux d’appauvrissement en cations et le régime hydrologique de ces rivières, Thompson et Bennett(1980) ont pu déduire que le pH moyen des précipitations atmosphériques en 1973 devait se situer vers 4. 1 ou 4. 2. Ou, en d’autres termes, la charge d’ions H+ dans le sud de la Nouvelle-Écosse devait se situer aux environs de 110 meq/m2 et, dans le bassin de la rivière Isle-aux-Morts, aux environs de 130 meq/m2. 7, record 1, French, - taux%20d%27appauvrissement%20en%20cations

The rate at which cations are leached from a drainage basin by chemical weathering can be called the cation denudation rate or, alternatively, the proton absorptive capacity (PAC). The Tusket and Medway Rivers in Nova Scotia have PACs of about 80 meq [per square meter by year]. ... The three rivers in Newfoundland have somewhat higher PACs than the Nova Scotia rivers - the Isle aux Morts River about 200 meq [per square meter by year], the Garnish and the Rocky Rivers about 150 meq [per square meter by year]. 2, record 2, English, - proton%20absorptive%20capacity

Les travaux de Thompson(1980) et d’autres du Canada mènent à des études comparatives d’épuisement des cations dans les bassins versants, en fonction de divers taux de retombées acides. Le taux d’appauvrissement en cations(TAC) peut aussi être considéré comme la capacité d’absorption des protons(CAP) du bassin. Thompson et al.(1980) signalent que les rivières Tusket et Medway de la Nouvelle-Écosse ont une CAP d’environ 80 meq [par mètre carré par an]. 4, record 2, French, - capacit%C3%A9%20d%27absorption%20des%20protons

Par "absorption" ou par "fixation", on entend la faculté qu’ont les protons d’être absorbés et non pas inversement leur faculté d’absorber. 5, record 2, French, - capacit%C3%A9%20d%27absorption%20des%20protons
