The disposition of methyl [2,3-14C]-acrylate (MA) and 2-ethylhexyl [2,3-14C]-acrylate (EHA) following intraperitoneal and oral administration to rats has been studied. The 14C found in the tissues was mainly associated with liver, kidneys and lungs. Loss of 14C from these tissues occurred fairly rapidly, excluding the rats given EHA intraperitoneally. Most of the administered acrylates underwent rapid metabolism and excretion with expired air (more than 50% of the dose and urine (10-50% of the dose). Significant differences in the rates of 14C loss from tissues and excretion occurred after intrapritoneal administration of MA and EHA. A possible cumulation of EHA in the organism was suggested.
对大鼠腹腔注射和口服[2,3 - 14C] - 丙烯酸甲酯（MA）和[2,3 - 14C] - 2 - 乙基己酯（EHA）后的处置情况进行了研究。组织中发现的14C主要与肝脏、肾脏和肺有关。除腹腔注射EHA的大鼠外，这些组织中14C的损失相当迅速。大部分给药的丙烯酸酯经历了快速代谢并通过呼出气体（超过剂量的50%）和尿液（剂量的10 - 50%）排泄。腹腔注射MA和EHA后，组织中14C损失率和排泄率存在显著差异。提示EHA可能在生物体内蓄积。
