^aCompounds that were also detected in technical DDT, Dicofol, or reported as a microbial transformation products of DDT are denoted by an “x”.

^bIdentification uncertainty categories are defined in the Materials and Methods section. Mass spectra and ancillary information associated with identification (i.e. GC×GC retention times, mass fragments, and corresponding standard mass spectrum) are available in SI Part B.
