Impact of phosphine exposure on development in Caenorhabditis elegans: Involvement of oxidative stress and the role of glutathione

► Phosphine induced developmental toxicity in C. elegans. ► Phosphine increased glutathione content in worms exhibiting developmental delay. ► Diethyl maleate, a glutathione depletor, significantly augmented phosphine-induced developmental delay. ► GSH appeared to be crucial for survival and development in worms under PH3 exposure.
