AbstractBirds have enough conditions to be used as bioindicators for the presence of environmental contaminants. Notably, chlorpyrifos (CPF) remains extensively employed in Argentina, particularly in fruit plantations and livestock settings This studyaimed to assess the potential impacts of CPF on common quail (Coturnix coturnix) embryos through external eggshellapplication during key embryonic stages (days 1, 4, and 14). Concentrations equivalent to those used in fruit applications,5× and 10×(38.4, 192, and 384 µg/egg), were employed. A 48% commercial formulation of CPF (Pirfos - Icona®) wasutilized. An increase in embryonic deaths, as well as a statistical association between the degree of liver or kidney lesionsand CPF concentrations was observed. The results suggest that CPF can induce embryotoxic effects with a single exposureto quail embryos and compromise the viability of the organisms. The study suggests a potential exposure risk for embryosthrough contact with the insecticide on the eggshell’s exterior.
