海水表面的重油（HO）渗透到鱼卵中，阻碍了鱼卵的正常形态发生。为了确定HO在鸡蛋类型下的毒理学效应，我们使用浮动鸡蛋和下沉鸡蛋进行了暴露实验。在发育过程中，暴露于ho的浮卵胚胎形态出现异常，而下沉卵的早期幼虫形态基本正常。然而，下沉卵发育中的周围神经系统出现异常突出。这些发现表明，暴露于HO的鱼类在发育神经元方面存在问题，尽管它们没有形态畸形。通过这些观察，我们得出结论，HO对漂浮卵的形态发生具有强烈的毒性，并且影响漂浮卵和下沉卵的神经元发育。(C) 2011 Elsevier Ltd.版权所有。
Heavy oil (HO) on the sea surface penetrates into fish eggs and prevents the normal morphogenesis. To identify the toxicological effects of HO in the context of the egg types, we performed exposure experiments using floating eggs and sinking eggs. In the course of development, HO-exposed embryos of floating eggs showed abnormal morphology, whereas early larva of the sinking eggs had almost normal morphology. However, the developing peripheral nervous system of sinking eggs showed abnormal projections. These findings suggest that HO exposed fishes have problems in the developing neurons, although they have no morphological malformations. Through these observations, we conclude that HO is strongly toxic to floating eggs in the morphogenesis, and also affect the neuron development in both floating and sinking eggs.
