Method

Ethical approval:
not applicable
Exposure assessment:
measured
Details on exposure:
Observations were done in chromosomes of workers exposed to ethyleneimine from some months to 23 years. Since 1966, regular analysis of the air always revealed a value of less than 0.5 ppm ethylenimine.

Results and discussion

Results:
Healthy control subjects presented a certain percentage of spontaneous chromosome aberrations.
The percentage of chromosome aberration for workers exposed to ethyleneimine was 1-4%, not higher than the spontaneous chromosome aberrations.

Any other information on results incl. tables

No more available data on the results.

Applicant's summary and conclusion

Conclusions:
The percentage of chromosome aberration for workers exposed to ethyleneimine was 1-4%, not higher than the spontaneous chromosome aberrations.
Executive summary:

This paper refers to the chromosome study carried out in chemical workers, exposed to different substances (ethyleneimine among them).

The investigations were recorded on chromosome damage of workers exposed to ethyleneimine from some months to 23 years. Since 1966, regular analysis of the air always revealed a value of less than 0.5 ppm ethylenimine. Healthy control subjects presented a certain percentage of spontaneous chromosome aberrations.

The percentage of chromosome aberration for workers exposed to ethyleneimine was 1-4%, not higher than the spontaneous chromosome aberrations.
