Abstract
|
|
|
For the purpose of obtaining reference data for the organic solvent poisoning, we analyzed the air trichloroethylene concentration and urinary total trichlorocompounds in workshop where trichoroethylene use wasging solvents.
Urine samples collected from 13 exposed workers (6 male, 7 female workers) and 10 nonexposed workers(7 male, 3 female workers) were analyzed for total tricholro-compounds and trichloroacetic acid.
Trichloroethylene concentration in working environments was conducted.
The resules were as follows;
1. Trichloroethylene concentration in washing tank and drying tank were 19.8-50.3 and 130.8-456.2 ppm, respectively.
2. Urinary total trichlorocompound levels and trichloroacetic acid level in 13 exposed workers were 577.0±240.9㎎/ℓ and 270.8±146.3㎎/ℓ,respectively. While non-exposed 10workers were 7.1±8.2㎎/ℓ and 0.5±1.0㎎/ℓ, respectirely The difference between two groups was statistically significant(P<0.001).
