中文摘要:
      考虑到人类社会中大量使用化学物质,想要准确有效地评估这些化学物质对人类和生态受体的潜在风险,研发有效的手段和方法是至关重要的。鱼胚胎急性毒性试验是其中一种工具,已表现出与幼鱼急性毒性标准试验的预测结果高度吻合,而幼鱼试验对资源消耗更多。然而,也有证据表明,对于某些类型的化学物质,包括神经毒素,鱼类胚胎的敏感性低于幼鱼。本文利用已发表的斑马鱼胚胎毒性数据,与3种常用检测用鱼幼鱼(虹鳟鱼、蓝鳃太阳鱼、羊鲷)的半致死浓度50%(LC50)数据进行比较,研究了鱼类胚胎对农药危害评估的效用。在将农药视为单因素的情况下,斑马鱼胚胎和幼鱼毒性数据相关性较差,差异显著(r2=0.28;p2=0.64;p 精选自Glaberman, S., Padilla, S. and Barron, M.

英文摘要:
      Given the numerous chemicals used in society, it is critical to develop tools for accurate and efficient evaluation of potential risks to human and ecological receptors. Fish embryo acute toxicity tests are 1 tool that has been shown to be highly predictive of standard, more resource-intensive, juvenile fish acute toxicity tests. However, there is also evidence that fish embryos are less sensitive than juvenile fish for certain types of chemicals, including neurotoxicants. The utility of fish embryos for pesticide hazard assessment was investigated by comparing published zebrafish embryo toxicity data from pesticides with median lethal concentration 50% (LC50) data for juveniles of 3 commonly tested fish species: rainbow trout, bluegill sunfish, and sheepshead minnow. A poor, albeit significant, relationship (r2?=?0.28;?p?2?=?0.64;?p? View more in http://onlinelibrary.wiley.com/doi/10.1002/etc.3641/full
