Abstract

While developing a method to analyze human adipose tissue for 2,3,7,8‐tetrachloro‐dibenzo‐p‐dioxin (TCDD) at the 1 ppt level, we observed several peaks with all of the analytical characteristics of TCDDs in the analyses of wipe tests and blank, quality control, and human adipose samples at concentrations equal to the low part‐per‐trillion level in a 10 g sample. The source of these contaminants was established to be a cleaning solution used to wash the floors in the laboratory performing the analysis.
