Table 2 Changes in the single-particle macropore network caused by the metals Fe and Ni.

Uncertainties have been determined as the SD of the changes (in percent) calculated using methods 1 and 2 for pore volume determination (see the Supplementary Materials). Nickel was not detected in the FRESH sample; therefore data on changes caused by Ni are not available (N/A).
