Abstract The effect of the herbicides paraquat and atrazine on erythroid differentiation has been studied in mouse erythroleukaemic cells.

Evaluation of cell viability under all the experimental conditions using either a trypan blue dye exclusion test or labelled chromium indicated that the effects observed were not related to a cytocidal action of atrazine or paraquat.
