The application of chemical dispersants is one option of oil spill response (OSR). Here, Northern shrimp (Pandalus borealis) larvae were experimentally exposed for short periods (6 h and 1 h) to a realistic concentration of chemically dispersed oil (CDO) (10 mg L THC), mechanically dispersed oil (MDO) (7 mg L THC), and dispersant only (D). A control (C) with seawater served as reference. Short-term effects on survival and feeding were examined right after exposure and longer-term consequences on survival, feeding, growth and development following 30 days of recovery. Both exposure durations provoked long lasting effects on larval fitness, with 1 h exposure leading to minor effects on most of the selected endpoints. The 6 h exposure affected all endpoints with more adverse impacts after exposure to CDO. This study provides important data for assessing the best OSR option relevant to NEBA (Net Environmental Benefit Analysis).
化学分散剂的应用是溢油应急响应（OSR）的一种选择。在这里，北方虾（Pandalus borealis）幼虫在短时间内（6 小时和 1 小时）暴露于实际浓度的化学分散油（CDO）（10mg/L THC）、机械分散油（MDO）（7mg/L THC）和仅分散剂（D）。用海水作为对照的控制组（C）。暴露后立即检查对存活和摄食的短期影响，并在 30 天恢复期后检查对存活、摄食、生长和发育的长期影响。这两种暴露时间都对幼虫的适应性产生了持久的影响，1 小时的暴露对大多数选定的终点只有轻微的影响。6 小时的暴露影响了所有的终点，在暴露于 CDO 后产生了更不利的影响。这项研究为评估与 NEBA（净环境效益分析）相关的最佳 OSR 选择提供了重要数据。
