[edit] Explanation of "Descriptors"
Congener descriptors give a shorthand notation for geometry and substituent positions. The 12 "Dioxin-like" congeners are those that display all four of descriptors.
[edit] CP0 / CP1
These 68 "Co-Planar" congeners include 20 with chlorine substitution at none (CP0, non-ortho) and 48 with chlorine substitution at only one (CP1, mono-ortho) of the 2, 2', 6, or 6' positions.
[edit] 4CL
These 169 congeners have a total of four or more chlorine substituents (regardless of position).
[edit] PP
These 54 congeners have both para positions (4 and 4') chlorinated.
[edit] 2M
These 140 congeners have two or more of the meta positions (3, 3', 5, and 5') chlorinated.
