When the congeners are grouped by chlorination level, each of these groups is referred to as a homolog. One of the challenges associated with PCBs is determining the type of analysis that may be required.Projects can require total PCBs, 7 or 9 PCB Aroclors, PCB Homologs, 209 individual PCB Congeners, co-planar PCB Congeners or other program specific lists of PCB Aroclors or Congeners.Treatment of croaker with -chlorophenylalanine, an irreversible TPH inhibitor, mimicked the effects of PCB on the Gn RH system and the LH response to Gn RHa.Bypassing the TPH-dependent hydroxylation step with the administration of 5-hydroxytryptophan restored 5-HT to control levels and prevented the deleterious effects of PCB on the neuroendocrine parameters.

Oftentimes, the regulatory framework can define the specification for the PCB analysis, or it can be defined based on the end use of the data or even the environmental matrices being analyzed.
