Abstract |
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 were made from chalk and petroleum pitch and molded at 190°C. No respiratory protective mask was worn. Atmospheric concentrations of pyrene and benzo(a)pyrene (BaP) ranged from 0.66 to 5.05µg/m3 and 0.037 to 0.270µg/m3 respectively, with a mean pyrene/BaP ratio of approximately 20 and a correlation r = 0.51. Maximum PyOH urinary excretion ranged from 1.84 to 10.9µmol/mol creatinine. The correlation between atmospheric pyrene and urinary PyOH concentrations was poor (r = 0.37). It improved considerably (r = 0.74) if the amount of pyrene inhaled over the shift and the corresponding amount of PyOH excreted were considered. The ratio of urinary excreted PyOH to the pyrene inhaled dose (with assumed retention of 100%), ranged from 0.18 to 0.70 (arithmetic mean =0.34). Although dermal absorption is significant, these results suggests that the respiratory tract is the main absorption route for pyrene. |
