[Evolution and transformation in animal organism of some polychlorobiphenyls (author's transl)].

Intoxication by pure polychlorobiphenyls and a commercial product is studied, in rats, after intraperitoneal and oral administration. Their fixation and excretion of their metabolites is greater by intraperitoneal than by oral administration. The only hydroxy metabolites, identified by means of synthesis, gas chromatography and mass spectrometry are, all, derivatives from trichlorobiphenyl. It appears that administration of commercial product induces a more rapid degradation of these compounds in animal organism.

[Experimental toxocologic study of some trichlorobiphenyl isomers].

The authors, after having performed the preparation of a few pure trichlorobiphenyl isomers, proceeded with a preliminary toxicological study of the rat which should then facilitate study for a commerical product. The fixation level of these compounds is considerably higher in lipids and in the spleen than in the other organs. Urinary elimination is very low compared with faecal excretion; furthermore, chromatographic analysis makes it possible to shed light on phenolic products of transformation in the excreta, some of which it was possible to identify with hydroxylated trichlorobiphenyls synthesized in the laboratory.
