note
en Note 2 to entry: Depending on the element and the soil matrix, the pseudo-total concentration is typically 70 % to 90 % of the true total concentration (3.537) (3.538).
en Note 1 to entry: Typically, a small insoluble proportion of the element under consideration is not removed from the matrix by the chosen extractants.
fr Note 2 à l’article: La concentration pseudo-totale est généralement comprise, selon l'élément et la matrice du sol, entre 70 % et 90 % de la valeur vraie de la concentration totale (3.537) (3.538).
fr Note 1 à l’article: En général, les solvants d'extraction choisis laissent dans la matrice une faible proportion insoluble de l'élément considéré.
