氨是一种广泛分布于地表沃茨的化学物质。其对水生生物的毒性主要是由于非电离（NH3）形式。美国环保局最近汇编了一份关于氨对水生生物毒性的广泛审查报告，其中大部分信息包括鱼类试验值和水生植物和无脊椎动物的有限数据。无脊椎动物被发现一般比鱼类更耐氨。这项实验室研究是一个更大的评估的一部分，在室外实验流氨氮的影响和以上得出的水质标准浓度进行评估。本实验室研究的主要目的是确定在环境季节性温度下河水中非电离氨对鱼类和无脊椎动物的相对敏感性。
Ammonia is a widely distributed chemical found in surface waters. Its toxicity to aquatic life is principally due to the un-ionized (NH3) form. An extensive review on ammonia toxicity to aquatic life has been recently compiled by the US EPA with most information consisting of fish test values and limited data available for aquatic plants and invertebrates. Invertebrates were found to be generally more tolerant to ammonia than were fishes. This laboratory study is part of a larger evaluation in assessing the impact of ammonia nitrogen in outdoor experimental streams at and above derived water quality criteria concentrations. Primary objective for this laboratory study was to determine the relative sensitivity of un-ionized ammonia to fish and invertebrates in river water at ambient seasonal temperatures.
