In situ burning (ISB) is an oil spill clean-up option used by oil spill responders to mitigate impacts on the marine environment. Despite advantages such as high efficiency and potential applicability for challenging areas such as the Arctic, the actual environmental side effects are still uncertain. Acute and sublethal effects of the water accommodated fractions (WAFs from 25 g oil/L seawater) of a pre-weathered North Sea crude (Oseberg Blend 200 °C+) and field generated ISB residue were evaluated on Northern shrimp (Pandalus borealis) larvae. The larvae were first exposed for 96 h to a serial dilution of seven concentrations, and then maintained for two weeks in clean seawater post-exposure. No acute (mortality) or sublethal effects (feeding, development, or growth) were detected in any of the ISB residue concentrations. Significant larvae mortality was found in the three highest concentrations of crude oil (96-h LC50:469 μg/L total petroleum hydrocarbon) but no sublethal effects were found in the surviving larvae post-exposure. This study indicates that applying ISB could mitigate acute impacts of spilled oil on shrimp larvae.

原位燃烧（ISB）是漏油应急响应者使用的溢油清理选项，可减轻对海洋环境的影响。尽管具有诸如在北极等具有挑战性的地区具有高效率和潜在适用性之类的优势，但实际的环境副作用仍然不确定。在北部虾（Pandalusborealis）上评估了预先风化的北海原油（Oseberg Blend 200°C +）的水份（WAS来自25 g油/ L海水）的急性和亚致死作用以及田间产生的ISB残留物）的幼虫。首先将幼虫暴露于7种浓度的系列稀释液中96小时，然后在暴露后的干净海水中保持2周。在任何ISB残留浓度下均未检测到急性（致命）或亚致死作用（进食，发育或生长）。在三个最高浓度的原油中发现了显着的幼虫死亡率（96-h LC50：469μg/ L总石油烃），但在暴露后的存活幼虫中未发现亚致死作用。这项研究表明，应用ISB可以减轻溢油对虾幼虫的急性影响。
