biphenyl

 [bi-fen´il]
polybrominated biphenyl (PBB) any of various brominated derivatives of biphenyl; uses and toxic hazards are similar to those of polychlorinated biphenyls. They typically are deposited in body fat stores and are rarely mobilized except through lactation.
polychlorinated biphenyl (PCB) any of various chlorinated derivatives of biphenyl, toxic and carcinogenic nonbiodegradable compounds used as heat-transfer agents and electrical insulators; they are readily absorbed from the gastrointestinal tract, and those with a lower percentage of chlorine are associated with a higher toxicity but are more readily excreted.

di·phen·yl

(dī-fen'il),
Colorless liquid; used as heat transfer agent, frequently as polychlorinated biphenyls (PCBs); as fungistat for oranges (applied to inside of shipping container or wrappers); and in organic syntheses. Produces convulsions and central nervous system depression.
Synonym(s): biphenyl, phenylbenzene

biphenyl

/bi·phen·yl/ (-fen´il) diphenyl.
polychlorinated biphenyl  (PCB) any of a group of chlorinated derivatives of biphenyl, used as heat-transfer agents and electrical insulators; they are toxic, carcinogenic, and non-biodegradable.

di·phen·yl

(dī-fen'il)
Colorless liquid that is used as a heat transfer agent, frequently as a polychlorinated biphenyl (PCB); used as fungistat for oranges and in organic syntheses. Produces convulsions and central nervous system depression.
Synonym(s): biphenyl, phenylbenzene.

biphenyl

polybrominated and polychlorinated biphenyls are widely used industrial chemicals, as flame retardants, heat transfer agents and electrical insulators.

biphenyl poisoning
these chemicals are not known to produce illness in the average environment, but they accumulate in fat and have a very slow rate of excretion and biodegradability. Experimental poisoning causes diarrhea, poor weight gain, growth retardation and abortion.

Du Bousquier, furious against Bonaparte, relating stories against him of his meanness, of Josephine's improprieties, and all the other scandalous anecdotes of the last ten years, was well received.
In vain the officer represented to Bartolomeo that he could not see the First Consul without having previously requested an audience in writing; the Italian insisted that the soldier should go to Bonaparte.
Bonaparte then spoke to him sharply, and the aide-de-camp, with evident unwillingness, left the room.
cried Bartolomeo, with a darkling look at Bonaparte.
Without me, your mother would never have reached Marseille," he said, addressing himself to Bonaparte, who was silent and thoughtful, his elbow resting on a mantel-shelf.
