Summary
A small group (n=12) of military white smok munition workers provided blood plasma during a production break (S I) and after five weeks' production (S II) of a hexachloroethane (HCE)/titanium dioxide formula. Plasma was also obtained from a sex and age matched control group (n=12) and a group (n=13) of previously HCE-exposed workers, respectively. HCE in plasma (P-HCE) was determined with gas chromatography and electron capture detection. No HCE was found in the plasma samples from the two control groups. In the HCE exposed group the mean (± SD) P-HCE level increased almost two orders of magnitude from S I (0.08 t 0.14 μg/l) to S 11(7.30 ± 6.04μg/l) despite efforts to minimize the internal dose. Biological monitoring of HCE could be useful in occupational hygiene.
