Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).

CAS Number. 608-93-5 ... PeCB was a component of a mixture of chlorobenzenes added to products containing polychlorinated biphenyls in order to reduce viscosity. [4]
In May 1999, there was a dioxin crisis in Belgium: quantities of polychlorinated biphenyls with dioxin-like toxicity had entered the food chain through contaminated animal feed. 7,000,000 chickens and 60,000 pigs had to be slaughtered. This scandal was followed by a landslide change in government in the elections one month later.
General chemical structure of polychlorinated triphenyls where 0≤x≤5 and 0≤y≤4 and 0≤z≤5. Polychlorinated terphenyls (PCTs) are a group of chlorine derivatives of terphenyls.
