Chromosome aberrations in the lymphocytes of persons working with the use of polychloropinene in agriculture

A cytogenetic examination of persons exposed to the action of polychlorpinene under agriculture conditions was carried out. The frequency of aberrant cells in the group of persons under examination accounted for 5.8 %, which was much higher than that of aberrations in the control group (1.6%). The average frequency of aberrant cells and character of aberrations under repeated cytogenetic examination 11 months after were similar to those described above.
