[Cytogenetic effects of synthetic resins in man]

The cytogenetic analysis of persons occupationally exposed to synthetic resins has revealed the reliable increase in the average frequency of cells with chromosome aberrations. The value obtained were 5,5% (146 persons) for epoxide resin, 6,1% (52 persons) for polyvinylchloride, 5,0% (31 persons) for phenolformaldehyde and 2,4% (74 persons) in the control. The average rate of aberrant chromosomes was 0,054 to 0,065 per cell for all synthetic resins, which differed significantly from the control. The average rate of chromosome breaks per chromosome did not reliably differ from that in the control.
