Figure 3: Comparative genotoxicity and cytotoxicity effects induced by zineb (black) and the zineb-based fungicide formulation Azzurro® (dark grey) commonly used in Argentina on in vitro (cylinders) mammalian Chinese hamster ovary (CHO-K1) cells and human lymphocytes (HL) and in vivo (prisms) A. cepa meristematic root cells. Results are expressed as fold-time values over control data (white pyramid). Evaluation was performed using end-points for genotoxicity [SCEs (A), SCGE (B), MN (C), and CA (D)] and cytotoxicity [MI (E) and PRI (F)].
