Neurotoxicity of 2,4-dichlorophenoxyacetic butyl ester in chick embryos

Fertilized hens' eggs were externally treated, before starting incubation, with a single dose of 2,4-Dichlorophenoxyacetic butyl ester (2,4-D b.e., 3.1 mg/egg). Chicks at different developmental stages were examined, extending from 10 day embryos to one day after hatching. Previously, we demonstrated that 2,4-D b.e. produces hypomyelination in chicks born… CONTINUE READING
