Wood, 2 months after the mines were buried. The relative percent differences are shown in parentheses
for replicate samples. (From Walsh and Ranney 1999.)*

*The PMA-1A mines were buried 2 cm to the top of the mine; the TMA-5 mines were buried 8.5 cm to the top. See Table 6.
†S--surface soil; T1--2-cm-long core just under surface soil; T2--core of soil between T1 and X; X--2-cm-long core of soil
just above the center of the mine's top surface.
**Below detection.
