In case of an oil spill, dispersant application represents a response option, which enhances the natural dispersion of oil and thus reduces coating of seabirds and coastal areas. However, as oil is transferred to the water phase, a trade-off of potential harmful effects shifted to other compartments must be performed. This paper summarizes the results of a workshop on the current knowledge on risks and benefits of the use of dispersants with respect to specific conditions encountered at the German sea areas. The German North Sea coast is a sensitive ecosystem characterised by tidal flats, barrier islands and salt marshes. Many prerequisites for a potential integration of dispersants as spill response option are available in Germany, including sensitivity maps and tools for drift modelling of dispersed and undispersed oil. However, open scientific questions remain concerning the persistence of dispersed oil trapped in the sediments and potential health effects.
如果发生石油泄漏，应用分散剂是一种应对措施，它可以增强石油的自然分散，从而减少海鸟和沿海地区的覆盖。然而，随着石油转移到水相，必须权衡潜在有害影响转移到其他隔室的问题。本文总结了一次研讨会的结果，该研讨会探讨了在德国海域遇到的特定条件下使用分散剂的风险和益处的现有知识。德国北海海岸是一个敏感的生态系统，其特点是潮滩、障壁岛和盐沼。德国有许多将分散剂作为应对溢油措施的潜在条件，包括敏感性图和用于分散和未分散石油漂移建模的工具。然而，仍有一些科学问题悬而未决，涉及被困在沉积物中的分散石油的持久性和潜在的健康影响。
