A. Fucic et al., A 9-YEAR FOLLOW-UP-STUDY OF A POPULATION OCCUPATIONALLY EXPOSED TO VINYL-CHLORIDE MONOMER, Mutation research. Section on environmental mutagenesis and related subjects, 361(1), 1996, pp. 49-53
The presence of structural chromosome aberrations and sister chromatid
exchange frequencies (SCE) were studied in lymphocytes from 28 male s
ubjects occupationally exposed to vinyl chloride monomer for a period
of 9 years, A significant increase in chromosomal damages and elevated
SCE frequencies was detected during the third and fourth year of the
follow-up study. During the last 2 years, all examined parameters are
approaching control values, This is a result of decreasing vinyl chlor
ide monomer concentrations in the working environment without interrup
ting the working process.
