    4 Pharmacology and Biochemistry
    4.1 Absorption, Distribution and Excretion

    ...POORLY ABSORBED & LARGELY EXCRETED UNCHANGED IN FECES.

    4.2 Metabolism/Metabolites

    Depending on the extent to which these compounds are absorbed, the various terphenyls were metabolized to glucuronic acid conjugates and phenol and excreted in the urine of treated rabbits. Following a single 1 gram oral dose of o-, m-, or p-terphenyl, 60% of the o-, 38% of the m-, and a trace of p-terphenyl were detected as their respective glucuronides in the urine. Zero, 15%, and 30% of the o-, m-, and p-terphenyls, respectively, were isolated unchanged in feces.
