Induction of chromosomal aberrations and sister chromatid exchanges by propane sultone in human lymphocytes in vitro

Genotoxicological investigation of 1,3-propane sultone was undertaken using human lymphocyte cultures as the test system. Concentrations greater than 1 mM induced appreciable chromosomal aberrations, which increased proportionally to the dose or the duration of treatment. It was also observed that treatment administered at 45 degrees C produced almost 3 times more abnormal cells than at 37 degrees C. The chemical also produced a significantly higher frequency of SCEs.
