title: Metaphase analysis of human lymphocytes treated with 4-chloromethylbiphenyl and benzyl chloride.
abstract: 4CMB and BC caused mitotic inhibition in human lymphocytes at low doses (greater than 20 and greater than 10 microgram/ml respectively). At non-inhibitory concentrations, neither substance produced increases in cells with breaks or breaks per cell, although 4CMB did induce a significant increase in gaps at dose. 4CMB and BC are not chromosome mutagens in this system.
