Pyrolysis-GC/MS Analysis of contaminated Soils in Alaska

摘要

In Alaska, the procedures used to quantify petroleum in organic soil are complicated by the presence of natural organic matter (NOM). A percentage of what appears to be contamination in some soil samples is actually NOM. The "contamination" derived from NOM (i.e., biogenic interference) cannot be quan- tified separately from petroleum using currently available analytical methods unless a "background" sample that is known to be uncontaminated can be obtained. Prov- ing that a background sample is truly uncontaminated is often problematic, if not impossible.
