[Individual dosimetry and biologic monitoring of workers exposed to low concentrations of aniline].
Low aniline vapours concentration exposure has been studied through either active or passive individual dosimeter, in a group of workmen employed in the production of an antioxidant for the rubber industry. We collected 28 samples, confirming the clear correlation existing between the two methods which was already demonstrated in a previous work. We newly suggest the usefulness of the individual passive dosimeter instead of the traditional vacuum pump system. Meanwhile we have determined bound and free aniline and total aromatic amines, with and without an extractive method on column, on urinary samples collected before and after the workshift. The values so obtained have been compared with the results of the active individual dosimetry. We could demonstrated a statistical significative correlation only between urinary aniline determination and the level of exposure, so confirming the value of this parameter as biological indicator of occupational exposure.
