Clastogenicity and aberration kinetics of some alkylarylnitrosoureas in Chinese hamster V79-E cells.

Six alkylarylnitrosoureas were checked for induction of chromosome aberrations and SCEs in Chinese hamster V79-E cells and compared with MNU, ENU and nitrosocarbaryl. All agents show a DNA-damaging activity. Studies of the dependence of aberration frequency on recovery time revealed drastic differences within this group of closely related substances.
