Polycyclic Aromatic Hydrocarbon Exposure in an Artificial Shooting Target Factory; Assessment of 1- Hydroxypyrene Urinary Excretion as a Biological Indicator of Exposure

摘要

Five representative workers and two external observers were monitored by personal air and urinary 1-hydroxypyrene (PyOH) sampling for a four-shift working week in an artificial shooting target factory. The targets (clay pigeons), are made from petroleum pitch and molded at 190℃. No respiratory protective mask was worn. Atmospheric concentrations of pyrene and benzo (a) pyrene (BaP) ranged from 0.66 to 5.05 μg/m~3 and 0.037 to 0.270 μg/m~3 respectively with a mean pyrene/BaP ratio of about 20 and a correlation r=0.51.
