Congeners

PCB congeners
(m = 0, 1, 2, 3, 4 or 5;
n = 0, 1, 2, 3, 4 or 5)

Example: BDE-99 , a congener of the PBDE

Congeners (also known as congeners ) are chemical compounds that are related by their origin or structure. Often they have the same tribe; H. the same basic structure. The sum formulas of two compounds that are congeners can differ; they are not necessarily isomers .

More congeneric compounds can have different chemical, physical, and toxicological properties. They often appear as a mixture .

Examples:

• Chlorinated paraffins
• Polychlorinated biphenyls (PCB) [mixture of up to 209 substances]
• Polychlorinated dibenzo- p- dioxins (PCDD)
• Polychlorinated Dibenzofurans (PCDF)
• Polychlorinated Carbazoles (PCCZ)
• Polychlorinated naphthalenes (PCN)
• Polybrominated dibenzo- p- dioxins (PBDD)
• Polybrominated Dibenzofurans (PBDF)
• Mixed halogenated dibenzo- p- dioxins (PHDD)
• Mixed halogenated dibenzofurans (PHDF)
• Polybrominated Diphenyl Ethers (PBDE)
• Polybrominated biphenyls (PBB)
• Polycyclic Aromatic Hydrocarbons (PAH)
