The dispersants Corexit 9527 and Corexit 9500 were extensively used during the response to the Deepwater Horizon accident in 2010. In addition to the monitoring programs established by federal and state governments, local communities also conducted studies to determine if chemical constituents from these dispersants impacted nearshore and inland waters. One community (the City of Orange Beach, Alabama) collected water samples between September, 2010 and January, 2011, and found the dispersant-related chemicals propylene glycol, 2-butoxyethanol, and dioctyl sodium sulfosuccinate at nearshore and inland water sampling sites. In this paper, we examine their dataset in an attempt to discern the origin of these chemicals. Our assessment indicates that these compounds are unlikely to be present as a result of the use of Corexit dispersants; rather, they are likely related to point and non-point source stormwater discharge.
在 2010 年应对深海地平线事故期间,分散剂 Corexit 9527 和 Corexit 9500 被广泛使用。除了联邦和州政府建立的监测计划外,当地社区也进行了研究,以确定这些分散剂中的化学物质是否对近岸和内陆水域产生影响。一个社区(阿拉巴马州奥兰治海滩市)在 2010 年 9 月至 2011 年 1 月期间采集了水样,并在近岸和内陆水域采样点发现了与分散剂有关的化学物质丙二醇、2-丁氧基乙醇和二辛基琥珀酸磺酸钠。在本文中,我们检查了他们的数据组,试图辨别这些化学物质的来源。我们的评估表明,这些化合物不太可能是由于使用 Corexit 分散剂而存在的;相反,它们可能与点源和非点源雨水排放有关。
