Chloranil (Tetrachloro-p-benzoquinone), an orally active metabolite of pentachlorophenol and hexachlorobenzene, is a widely used fungicide. Chloranil can induce ROS production. Chloranil induces neutrophil extracellular traps through the ROS-JNK-NOX2 pathway. Chloranil induces ferroptosis and neuroinflammation. Chloranil induces apoptosis of mouse embryonic stem cells[1][2][3][4][5] .
