Resumen |
Examination of 8 persons who were occupationally exposed to about 50ppm (260mg/m3) trichloroethylene (the TLV in the Fed.Rep. of Germany) in a printing shop is reported. The purpose of the psychological examinations was to clarify mental function changes correspnding to a "psycho-organic syndrome". In spite of proved incorporation of solvent, no signs of CNS changes were found. Biochemical analysis showed large interindividual variations of trichloroethylene, trichloroethanol and trichloroacetic acid levels in blood and urine and a fall in concentrations after exposure-free intervals. The level of 250mg trichloroethanol and trichloroacetic acid per gram of creatinine, under discussion as an acceptable biological TLV in occupational medicine, was exceeded in all cases. It is proposed to increase it to 300-350mg total metabolites per gram of creatinine. The results are compared with other reports. |
