Static exposure experiments were conducted to assess the toxicity of dispersed Prudhoe Bay Crude Oil (PBCO) to embryos of the topsmelt (Atherinops affinis). Treatment with the dispersant COREXIT 9500 resulted in greater hydrocarbon concentrations in chemically enhanced water-accommodated fractions (CEWAFs) of oil, relative to the untreated water-accommodated fractions (WAFs). Topsmelt embryo development and survival to hatching was significantly inhibited in CEWAF tests while minimal effects on embryo-larval survival were observed in WAF tests. Increased hydrocarbon concentrations in the CEWAF tests caused cardiovascular and other abnormalities in developing topsmelt embryos.
进行了静态暴露实验,以评估分散的普拉德霍湾原油(PBCO)对尖吻银汉鱼(Atherinops affinis)胚胎的毒性。与未处理的水相组分(WAFs)相比,使用分散剂COREXIT 9500处理后,油的化学增强水相组分(CEWAFs)中的碳氢化合物浓度更高。在CEWAF测试中,尖吻银汉鱼胚胎发育和孵化存活率受到显著抑制,而在WAF测试中观察到对胚胎-幼体存活率的影响最小。CEWAF测试中碳氢化合物浓度的增加导致发育中的尖吻银汉鱼胚胎出现心血管和其他异常。
