  1. PCT9Rp was extracted at approximately the same location and depth as PCT9R; (*) as-excavated powder samples ignited in laboratory at 880 °C in air with a heating rate of 200 °C/h, and a dwell time of 1 h. Two categories of soils were defined: low depth soils (< 1.53 m) and high depth soils (2.5 and 3 m).
