  1. Toxicokinetics and biological monitoring in experimental exposure of humans to gaseous hexahydrophthalic anhydride.

    Article - En anglais

    Six healthy volunteers were exposed to gaseous hexahydrophthalic anhydride (HHPA) concentrations of 10, 40, or 80 mug.m-3 (65, 260 or 520 nmol.m-3, respectively) for 8 h. The respiratory uptake of the inhaled HHPA was almost complete.

    Rapid increases in plasma and urinary levels of hexahydrophthalic acid (HHP acid) were seen.

    During the first 4 h after the end of exposure, the half-time of HHP acid in plasma was about 2 h. A corresponding decay was seen in urine.

    The correlations (r>0.90) between the air concentrations of HHPA and the levels of HHP acid in plasma and urine were close.
