Di(2-ethylhexyl)phthalate(DEHP)is a widely used plasticizer known for its reproductive developmental and immune system toxicity,mainly through esophagal,dermal,and respiratory exposure^([1-3]).Maternal exposure to DEHP during pregnancy can lead to adverse birth outcomes in offspring,including impacts on the thyroid system of adolescent offspring^([2-4]).
