The frequency of structural chromosome aberrations and sister-chromatid exchanges in peripheral blood lymphocytes of nurses handling cytostatic drugs without a safety cover is compared with that of individuals doing this work exclusively under a safety cover and with that of nurses working under similar conditions but not handling cytostatics. The mean yield of dicentric chromosomes, (4.3 +/- 0.7)/1000 cells, and acentric fragments, (15.4 +/- 1.4)/1000 cells, in the occupationally exposed group is significantly increased in comparison to individuals working with protection (dic: (1.1 +/- 0.4)/1000 cells, ace: (11.2 +/- 1.2)/1000 cells) and nurses not handling cytostatics (dic: (2.1 +/- 0.5)/1000 cells, ace: (9.9 +/- 1.1)/1000 cells). The frequency of chromatid breaks and SCE is not significantly different between these groups (p greater than 0.05).
