| 摘 要： | 搜集筛选了我国海洋生物的25种氨氮急性毒性数据，采用美国水生生物基准技术对氨氮水生生物基准进行推算，得出保护我国海水生物的氨氮急性基准值为0.085 mg·L-1，慢性基准值为0.013 mg·L-1，并利用荷兰基准技术对该计算结果进行验证，结果表明与美国基准技术方法比较接近。应用获得的氨氮基准值对大辽河口进行氨氮暴露风险分析，结果表明，13个站位均存在一定的生态风险，季节对氨氮暴露浓度水平具有重要影响，枯水期氨氮暴露风险显著大于丰水期，呈现数量级差异。大辽河口水体氨氮暴露浓度对水生生物的胁迫风险顺序为腔肠动物＞甲壳动物＞鱼类＞软体动物＞环节动物。研究结论可为氨氮水质标准制定和河口水环境管理提供技术支持。
