Glyphosate is the active component of many commonly used herbicides; it can reach bodies of water through irrigated rice plantations. In the present study, we evaluated the effect of glyphosate and Roundup(a glyphosate-based herbicide) in established culture of the zebrafish hepatocyte cell line ZF-L after 24 and 48 h of exposure to concentrations of 650 and 3250 µg/L. We observed a reduction in metabolic activity and lysosomal integrity, and an increase in cell number after 24 h of Roundupexposure at the highest concentration. An increase in active mitochondria and apoptotic cells was observed following 24 h exposure to glyphosate and Roundup, while only exposure to Roundupinduced an increase in necrotic cells. Rhodamine B accumulation decreased after 48 h exposure to 650 µg/L of Roundup; this reduction is indicative of increased activity of ABC pumps. Overall, the present findings highlighted the hazard of glyphosate exposure not only in the commercial formulation but also glyphosate alone, since both can induce damage in the ZF-L cell line primarily through the induction of apoptosis.
