  1. Measured concentrations of Cs, Fe, and Mg were below a detection limit of 0.2, 0.0002 and 0.001 mM, respectively. Measured values for Zn ranged from 0.0003 to 0.001 mM and were in the range of the detection limit
  2. – Not determined
  3. aValues for OH refer to the free concentration as calculated from the measured pH values
